New research suggests that a ring formed around the Earth about 466 million years ago, potentially explaining an unusually high number of meteor impacts and influencing the planet’s climate. Earth’s history with cosmic materials includes the wellknown Chicxulub impact that wiped out the dinosaurs, but there were earlier impacts, particularly during the Ordovician period.
Scientists have long been puzzled by the discovery of 21 impact craters near the equator, despite 70% of Earth’s land mass being outside this region. Typically, asteroid impacts occur randomly, as seen on the Moon and Mars, but this pattern of Ordovician impacts was concentrated in a small area.
Professor Andy Tomkins and his team at Monash University explored this phenomenon by studying stable land regions from that time. Using GIS technology, they pinpointed areas like Western Australia, Africa, and North America as regions likely to preserve impact craters. However, only 30% of these regions were near the equator, where all recorded impacts occurred, which is statistically improbable.
The team hypothesizes that a large asteroid approached Earth, broke up near the planet’s Roche limit, and formed a debris ring. Over time, this ring’s material fell to Earth, creating the spike in meteorite impacts seen in the geological record.
Evidence of this debris is found in sedimentary rocks from the period, containing unusually high amounts of meteorite material. This ring may also have cast a shadow over Earth, contributing to a cooling event known as the Hirnantian Icehouse near the end of the Ordovician period.
This finding highlights how celestial events may have played a significant role in Earth’s climate and evolutionary history, sparking questions about whether Earth had other rings in the past.
A study published in Neurology suggests that closely following the MIND diet may lower the risk of cognitive impairment, with a stronger effect observed in women and Black participants.

A study published in Neurology, the journal of the American Academy of Neurology, suggests that individuals whose diets closely follow the MIND diet may have a lower risk of cognitive decline. This association was observed in both Black and white participants. However, the findings show a correlation rather than proving that the MIND diet directly prevents cognitive impairment.
The MIND diet combines elements of the Mediterranean and DASH diets, emphasizing leafy green vegetables like spinach, kale, and collard greens, alongside other vegetables. It also
recommends whole grains, olive oil, poultry, fish, beans, nuts, and prioritizes berries over other fruits. The diet suggests consuming at least one serving of fish per week.
“With dementia rates rising as the population ages, it’s vital to identify changes that can delay or slow the onset of cognitive decline,” said study author Dr. Russell P. Sawyer of the University of Cincinnati in Ohio and a member of the American Academy of Neurology.
“We were particularly interested in whether diet influences the risk of cognitive impairment in both Black and white participants.”
The study followed 14,145 participants with an average age of 64, of which 70% were white and 30% were Black, over an average period of 10 years.
Participants completed a questionnaire about their diet over the past year, and researchers assessed how closely their food intake aligned with the MIND diet. Points were awarded for specific dietary habits, including: three or more daily servings of whole grains, six or more weekly servings of green leafy vegetables, one or more daily servings of other vegetables, two or more weekly servings of berries, one or more weekly servings of fish,
two or more weekly servings of poultry, three weekly servings of beans, five daily servings of nuts, four or fewer weekly servings of red meat, one or fewer weekly servings of fast or fried foods, one or more weekly servings of olive oil, one or fewer tablespoons of butter or margarine daily, five or fewer weekly servings of pastries and sweets, and one daily glass of wine. The maximum score was 12.
Researchers divided participants into three groups based on their diet scores: the low group had an average score of five, the middle group had an average score of seven, and the high group averaged nine.
Participants’ thinking and memory skills were assessed at the start and end of the study. Cognitive impairment occurred in 532 people, or 12%, out of 4,456 in the low diet group; 617 people, or 11%, out of 5,602 in the middle group; and 402 people, or 10%, out of 4,086 in the high group.
After adjusting for factors like age, high blood pressure, and diabetes, researchers found that individuals in the high group had a 4% lower risk of cognitive impairment compared to those in the low group.
When analyzing gender differences, researchers found a 6% reduced risk
for cognitive impairment in women who followed the diet closely, but no significant decrease for men.
They also examined the rate at which participants’ cognitive skills declined. Those who adhered more closely to the MIND diet experienced slower cognitive decline, with a stronger effect observed in Black participants compared to white participants.
“These findings call for further research, particularly to explore the differing impacts among men, women, and Black and white individuals. It’s promising to think that simple dietary changes could reduce or delay cognitive issues,” said Sawyer.
A limitation of the study was its focus on older Black and white participants, so the results may not apply to other populations.
Precisely detonating a nuclear bomb above an approaching asteroid could be our best chance of avoiding a catastrophic impact.Precisely detonating a nuclear bomb above an approaching asteroid could be our best chance of avoiding a catastrophic impact.
A laboratory experiment conducted by an international team of researchers showed that the X-rays generated by a suitably sized nuclear explosion could shift asteroids about 3 to 5 kilometers in diameter off their trajectory.
While scientists do not presently need such an anti-catastrophe device, they recognize that the threat of unexpectedly encountering a near-Earth asteroid is serious enough to warrant the creation of a robust disaster prevention plan.
Recently, NASA showed that a heavy space probe could deflect a small pile of rocks from Earth’s path with a strong collision. The smaller component of the Dimorphos and Didymos binary system, under 800 meters in diameter and made of loose gravel, was displaced from its orbit, boosting scientists’ confidence in using directed collisions to shift similarly sized objects away from Earth.
While these results are promising, researchers clearly need more data before they can attempt to deflect any asteroid by merely hurling probes at them. A larger, more solid asteroid could pose a completely different challenge.
Fortunately, there are other ways to move an asteroid. Attaching it to a powerful fusion engine or using focused lasers to evaporate part of its surface and create a rocket-like effect are some options.
However, one feasible method involves heating a small area of the asteroid’s surface with intense radiation, which could vaporize minerals and generate gases that push the asteroid off its course.
Researchers can test the basic principles of evaporating rock with electromagnetic radiation on Earth, making adjustments for different materials and mineral structures.
Moore, from Sandia National Laboratories in the U.S., used a high-frequency electromagnetic wave generator called the Z Pulsed Power Facility to release 1.5 megajoules of X-rays into a tank of argon gas.
This radiation “bubble” destroyed a thin metal foil holding a grain of fused silica (or quartz glass), suspending the sample just long enough to simulate a small asteroid drifting through space.
Moments later, the X-ray pulse hit the target, stripping micrometers from its surface and generating shock waves that provided crucial data.
These results could help predict the effects of a larger X-ray burst in the interplanetary vacuum. The momentum transfer suggests that asteroids up to 5 kilometers in diameter could theoretically be shifted using this method.
The team reported that researchers can test detailed models, such as the radiation-hydrodynamic model shown here and in other studies, against experimental data from this technique to refine predictions for asteroid intercept missions.
Of course, researchers know that asteroids consist of more than just fused silica; they often contain a mix of volatile materials arranged in various ways. By using this approach,
scientists can test different scenarios without needing to launch expensive missions and wait years for results.
Ideally, scientists will never need this knowledge. Although predictions indicate that some city-killer asteroids will pass dangerously close to Earth, none currently pose an immediate threat.
Still, no one likes surprises.If a real threat comes hurtling out of the darkness, we should know exactly how to blast it back into oblivion.
The most probable method for detecting life on a distant exoplanet is by identifying a biosignature. This involves analyzing the atmospheric spectra of the planet to find the distinctive spectral pattern of a molecule that can only be produced through biological activity.
Although it seems straightforward, detecting life on exoplanets is far from simple. The presence of basic molecules like water and oxygen doesn’t confirm the existence of life, as geological processes can also generate significant amounts of oxygen. While Earth’s oxygen-rich atmosphere is largely due to life, it’s not the only possible source.
Moreover, as a recent study reveals, some molecules we’ve long considered as biological markers might not be exclusive to life. Ideally, astronomers would prefer to find evidence of a complex molecule like chlorophyll. However, chlorophyll is unlikely to exist in large quantities in an atmosphere, making its spectral pattern faint and difficult to identify.
As a result, astronomers typically focus on simpler, yet distinctive, molecules. One such molecule is dimethyl sulfide (DMS), or (CH3)2S, which on Earth is produced only by phytoplankton, making it a strong candidate as a biosignature—or so it was thought.
In the new study, researchers successfully synthesized DMS and other sulfur-based molecules in the lab without any biological input. Although this doesn’t prove the process occurs naturally, the team further demon-
strated how DMS could potentially form on a planet with a dense organic haze.
We know planets like this exist because Saturn’s moon Titan is one such example. If Titan were closer to the Sun, ultraviolet radiation could be strong enough to initiate the chemical reactions needed to produce DMS.
If Titan were in Earth’s orbit, distant aliens would detect DMS in the atmosphere of a planet within the Sun’s habitable zone. It would seem like strong evidence for life, but Titan would still be inhospitable to life as we know it.
However, Titan could host some form of exotic life, which is another takeaway from this study. While the authors demonstrate that DMS or similar molecules alone don’t confirm the presence of life, they suggest it would indicate a high potential for it.
Essentially, a warm planet with a dense organic haze in its atmosphere would likely contain the complex organic molecules necessary for life to evolve. The existence of DMS on such a world, therefore, would at least imply the potential for life.
This study underscores the need for
caution when interpreting certain molecules as biosignatures, but it also reinforces what exo-biologists have suspected for a while.
Discovering life on another planet probably won’t come from a single dramatic moment. Instead, several planets may show chemical markers hinting at the possibility of life. As we identify more of these potential biomarkers in their atmospheres, our confidence in the existence of extraterrestrial life will grow steadily.
The most probable method for detecting life on a distant exoplanet is by identifying a biosignature. This involves analyzing the atmospheric spectra of the planet to find the distinctive spectral pattern of a molecule that can only be produced through biological activity.
Fortunately, NASA is advancing plans to implement a standardized time zone on the Moon. The proposed Coordinated Lunar Time (LTC) would help schedule missions and explorations, making future efforts to establish a permanent base on the lunar surface somewhat easier.
While the concept has been previously discussed, NASA has announced plans to collaborate with the U.S. government, commercial partners, and international standards organizations to ensure we always know the time on the Moon.
“As the commercial space industry expands and more countries engage in lunar activities, the need for time standardization increases,” explains aerospace engineer Ben Ashman from NASA’s Space Communications and Navigation (SCaN) team.
“A shared definition of time is essential for safe, resilient, and sustainable operations.”
NASA researchers aim to utilize atomic clocks on the Moon, similar to those used on Earth. These clocks operate based on the energy frequency required for electrons to transition between states in specific atoms, allowing for extremely precise timekeeping.
However, there is a challenge: gravitational differences between Earth and the Moon result in variations in the length of each second. Consequently, timepieces on the lunar surface will gain approximately 56 microseconds per day compared to those on Earth.
“As something travels at the speed of light, 56 microseconds is sufficient time to cover about 168 football fields,” says Cheryl Gramling, a senior navigation systems engineer at NASA.
“If someone is orbiting the Moon, an observer on Earth who doesn’t account for the effects of relativity over a day would perceive the orbiting astronaut as being about 168 football fields away from their actual position.”
Scientists are diligently working on the mathematical models needed to address this complex issue and ensure better synchronization between the watches of astronauts and ground control operators.
Once these obstacles are resolved, NASA scientists believe the system will be effective enough to be applied throughout the Solar System, not just on the Moon, which will be beneficial for scheduling video calls to Mars in the future.
To conclude, the development of Coordinated Lunar Time is a crucial component of the Artemis project, NASA’s initiative to establish a longterm human presence on the Moon. However, the next astronaut mission to the lunar surface, which will include the first woman and the first person of color to walk on the Moon, is planned for 2026.
In “Towards Human-Level Artificial Intelligence,” Eitan Michael Azoff suggests that deciphering the neural code and replicating visual thinking are essential steps for AI to surpass human intelligence.
According to an AI expert, grasping how ‘visual thinking’ functions is crucial for developing human-level AI. He suggests that computers might be capable of mimicking a form of consciousness but also cautions that
society must regulate AI technology and maintain exclusive control over the ‘off switch.’
According to AI technology analyst Eitan Michael Azoff, humans will create AI that surpasses our abilities once we decipher the ‘neural code.’ Azoff explains that this breakthrough will enable us to engineer intelligence with greater speed and capacity than the human brain.
The key to this advancement lies in understanding how the brain encodes sensory information and processes it for cognitive functions like thinking, learning, problem-solving, internal visualization, and internal dialogue.
In his book Towards Human-Level Artificial Intelligence: How Neuroscience can Inform the Pursuit of Artificial General Intelligence, Eitan Michael Azoff argues that a key step in creating ‘human-level AI’ is replicating consciousness in computers.
Azoff points out that there are various forms of consciousness, with scientists recognizing that even simpler creatures like bees possess some level of consciousness, though without
self-awareness. Humans experience something similar when fully immersed in a task, often referred to as being “in the flow.”
He suggests that a virtual brain could be created through computer simulation, which could initially mimic consciousness without self-awareness. This type of consciousness allows animals to plan actions, anticipate events, and recall past experiences, and it could serve the same purpose for AI.
Visual thinking may hold the key to understanding the nature of consciousness. While current AI relies on large language models (LLMs) and doesn’t “think” visually, Eitan Michael Azoff notes that visual thinking came before language in human evolution. He suggests that unraveling visual thinking and modeling visual processing will be a vital step in developing human-level AI.
Azoff explains, Once we crack the neural code, we will create faster and more advanced brains with greater capacity, speed, and enhanced technology that will surpass the human brain.
“We will begin by modeling visual processing, which will allow us to replicate visual thinking. I believe that from this, a form of ‘in-the-flow’ consciousness will emerge. I do not think a system needs to be alive to possess consciousness.”
Azoff also offers a caution, urging society to regulate AI technology to prevent potential misuse. He emphasizes, Until we can fully trust the machines we create, two key measures must always be in place.
“First, humans must retain sole control over the off switch. Second, AI systems should be built with embedded behavior safety rules.”
The plan is to transfer these traits to current animals by engineering their genes. Since the Asian elephant is 99.6% genetically similar to the woolly mammoth, it serves as the primary model for this research.
Eriona Hysolli, Head of Biological Sciences at Colossal Biosciences, explained that generating induced pluripotent stem cells from elephants was a major goal. These cells could help study Arctic adaptation and aid conservation efforts through advanced reproductive technologies.
The environmental impact of reintroducing woolly mammoths could be significant. Elephants’ role in tree management could help restore ecosystems degraded by human activity. As trees trap more heat and snow, they contribute to warming and carbon release, which could be mitigated by reintroducing megafauna to maintain grasslands.
Colossal Biosciences has announced a world-first achievement: their goal is to create a woolly mammoth by 2028. Their approach involves reprogramming elephant cells into stem cell-like cells capable of differentiating into all necessary cell types. This breakthrough centers on identifying genes linked to key mammoth traits such as cold tolerance and curved tusks.
Woolly mammoths, by knocking down trees, could help maintain these ecosystems. Their presence could have a substantial environmental benefit, comparable to the estimated $70,000 annual value of elephants’ carbon sequestration.
This breakthrough, detailed in a preprint on bioRxiv, marks a significant step, though there’s still progress to be made. Colossal Biosciences is exploring various methods to accel-
erate and refine the process, aiming to make significant strides in both de-extinction and conservation.
While many of us take the ground beneath our feet for granted, it holds Earth’s complex history within its layers, like pages of a book. Research suggests there are lesser-known chapters in that history, buried deep in Earth’s past. In fact, Earth’s inner core seems to have another, even more internal core within it.
Traditionally, we have learned that Earth has four main layers: the crust, the mantle, the outer core, and the inner core, explained geophysicist Joanne Stephenson from the Australian National University in 2021.
Our understanding of what lies beneath Earth’s crust comes largely from what volcanoes reveal and what seismic waves suggest. Based on these indirect observations, scientists have estimated that the extremely hot inner core, with temperatures exceeding 5,000 degrees Celsius (9,000 Fahrenheit), accounts for only 1% of Earth’s total volume
However, a few years ago, Stephenson and her colleagues found evidence that Earth’s inner core may actually consist of two distinct layers.
This is very exciting and could mean we have to rewrite the textbooks! Stephenson said at the time.
So, what’s down there? The team examined models of inner core anisotropy—how variations in its material affect the properties of seismic waves—and found that some models were more likely than others.
While some suggest that the inner core’s material channels seismic waves faster along the equator, others indicate that the mix of materials allows for faster waves along Earth’s rotational axis. Even then, there is debate over the exact degree of difference at certain angles.
The study did not show much variation with depth in the inner core, but it did find a shift in the slower direction at a 54-degree angle, with the faster direction of waves aligned with the axis.
“We found evidence that may indicate a change in iron’s structure, suggesting perhaps two separate cooling events in Earth’s history,” Stephenson explained.
The details of this major event are still somewhat mysterious, but we’ve added another piece to the puzzle when it comes to our understanding of Earth’s inner core.
These findings might explain why some experimental evidence has been inconsistent with our current models of Earth’s structure.
The presence of an innermost layer has been suspected before, with hints that the iron crystals making up the inner core have different structural alignments.
“We are limited by the distribution of global earthquakes and receivers, especially at polar antipodes,” the team
wrote in their paper, explaining that the lack of data decreases the certainty of their conclusions.
Still, their conclusions align with other studies on the anisotropy of the innermost core.
Future research may fill in some of these data gaps, allowing scientists to confirm or refute their findings and hopefully uncover more stories written in this early layer of Earth’s history.
Robot-to-Drone Food Deliveries Launch in Dallas
The Serve delivery robot will pick up the food order at the restaurant, drop it off at a Wing Auroloader collection point, and then Wing’s drone will take to the air for the final leg of the delivery to the customer Serve Robotics
While still not entirely common, rolling robots have been delivering goods to local customers for some
time, and drones have been transporting packages overhead. Now, Serve Robotics and Wing Aviation are set to combine these two delivery methods.
Wing, a subsidiary of Google’s parent company Alphabet, has been transporting small packages by air since at least 2018, with earlier development under Alphabet’s Project X.
The company’s “highly automated” battery-powered drones have delivered a variety of items, including medicine, library books, hot coffee, and fresh cookies, to hundreds of thousands of customers in Australia, the US, Finland, and Ireland.
Serve Robotics, backed by Uber, hasn’t been operating its delivery robots on US sidewalks as long, but the company has completed tens of thousands of deliveries for partners like Uber Eats and 7-Eleven. Now, Serve Robotics and Wing are joining forces to expand the reach of these rolling delivery robots in Dallas, TX.
Serve’s Robots and Wing’s Drones for Seamless Delivery
In the pilot project, Serve’s robots will collect food orders from restaurants and transport them to an Autoloader within a few blocks. From there, a Wing drone will take over, flying the items up to 6 miles to customers using its hybrid multi-rotor/fixed-wing design.
“We’re excited to partner with Wing to provide a multi-modal delivery service, expanding from handling deliveries within 2 miles to offering 30-minute autonomous delivery citywide,” said Serve CEO and co-founder, Dr. Ali Kashani.
Wing CEO, Adam Woodworth, added, “This partnership allows us to reach more merchants in congested areas while helping Serve expand its delivery range.”
To conclude, the partnership claims that the robot-to-drone delivery model eliminates the need for businesses to invest in extra infrastructure for long-range deliveries. It also suggests that this approach could reduce costs for both service operators and customers. The duration of the pilot has not yet been disclosed.
Tesla’s Optimus robot is a game-changer, blending advanced AI with sleek design to handle everyday tasks. Set to transform homes and workplaces, it’s the future of robotics made accessible today.

Climate change is increasing the susceptibility of Florida’s Big Bend region to tropical hazards
Helene hit Florida’s Big Bend as a Category 4 hurricane, bringing life-threatening storm surges and flooding. Its size, combined with the region’s vulnerable geography, creates severe storm conditions. The Gulf’s shallow waters and loss of natural seagrass are worsening flooding risks. Climate change is fueling stronger hurricanes by raising sea levels and warming ocean temperatures.
https://bit.ly/3TRuWEu
How climate change worsens storms like Hurricane Helene
Climate change is intensifying hurricanes like Helene, which recently struck Florida as a Category 4 storm. Warmer oceans transfer more energy to the atmosphere, making hurricanes stronger and causing faster intensification, as seen with Helene’s rapid growth. Additionally, rising temperatures are leading to heavier rainfall and higher sea levels, worsening the impact of these storms.
Experts like Claudia Benitez-Nelson and Jennifer Collins emphasize that reducing emissions is key to preventing further climate-related damage, as these more intense storms continue to threaten vulnerable regions.

Climate change is a pollution threat, like DDT and acid rain
Climate change may feel daunting, but history shows we’ve overcome similar challenges. Public pressure led to regulations on pollutants like DDT, lead, and sulfur dioxide, saving ecosystems and public health. Today, we face similar industry resistance, but climate action is growing. Countries are investing in renewable energy, and international agreements are supporting the shift away from fossil fuels.

A type of quark matter thought to be incredibly dense and found in the core of neutron stars.
Solution to the previous brainteaser:
In this puzzle, 3 equals 4 because in the equation 3 + 5 = 9, 3 is being inflated by 1 to make it work, so 3 must really be 4.
MIT’s Clio runs in real-time to map task-relevant objects in a robot’s surroundings, allowing the bot (Boston Dynamic’s quadruped robot Spot, pictured) carry out a natural language task (“pick up orange backpack”). Credit: Massachusetts Institute of Technology
Picture tidying up a cluttered kitchen, beginning with a counter scattered with sauce packets. If your aim is to clean the counter, you might gather all the packets at once. But if you want to separate the mustard packets first, you’d sort them by type. And if you were specifically looking for Grey Poupon mustard, you’d need to search even more carefully to find that exact brand.
MIT engineers have developed a method that enables robots to make intuitive, task-specific decisions. Their new system, called Clio, allows a robot to identify the important parts of a scene based on its assigned tasks. Clio processes a list of tasks in natural
language, determining the necessary level of detail to interpret its surroundings and “remember” only the relevant aspects.
In tests, Clio was used in environments like a cluttered cubicle and a five-story building, where the robot segmented scenes based on tasks such as “move rack of magazines” and “get first aid kit.” The system was also tested on a quadruped robot in real-time as it explored an office building, recognizing only objects related to its task, such as retrieving a dog toy while ignoring office supplies.
A Versatile Tool for Task-Specific Robotics
Named after the Greek muse of history for its ability to remember key elements, Clio is designed for use in various environments, including search and rescue, domestic tasks, and factory work. According to Luca Carlone, associate professor in MIT’s Department of Aeronautics and Astronautics, Clio helps robots understand their surroundings and focus on what’s necessary to complete their mission.
The team presents their findings in a study published today in the journal IEEE Robotics and Automation Letters. Carlone’s co-authors include SPARK Lab members Dominic Maggio, Yun Chang, Nathan Hughes, and Lukas Schmid, as well as MIT Lincoln Laboratory researchers Matthew
Trang, Dan Griffith, Carlyn Dougherty, and Eric Cristofalo.
Transitioning from Closed-Set to Open-Set Object Recognition
Advances in computer vision and natural language processing have enabled robots to identify objects, but this was previously limited to controlled “closed-set” environments with predefined objects. Recently, researchers have adopted an “open-set” approach, using deep learning to train neural networks on billions of images and text. These networks can now recognize new objects in unfamiliar scenes. However, a challenge remains in determining how to segment a scene in a task-relevant way. As Maggio notes, the level of detail should vary depending on the robot’s task to create a useful map.
With Clio, the MIT team designed robots to interpret their surroundings with detail that adjusts automatically to the task. For instance, if the task is to move a stack of books, the robot should recognize the entire stack, while it should identify just a green book when that’s the focus.
Integrating Computer Vision and Language Models for Enhanced Object Recognition
The approach combines advanced computer vision and large language models, using neural networks trained on millions of images and text. They also employ mapping tools that
segment images, which the neural network analyzes for relevance.
By applying the “information bottleneck” concept, they compress image data to keep only the segments relevant to the task, allowing the robot to focus on the necessary items.
Clio was tested in real-world environments, such as Maggio’s cluttered apartment, where it quickly identified relevant segments for tasks like “move pile of clothes.” The system was also used in real-time on Boston Dynamics’ Spot robot, which mapped and identified objects in an office.
This method generated maps highlighting only the target objects, enabling the robot to complete tasks efficiently. Running Clio in real-time was a major advancement, as prior methods required hours for processing.
Looking ahead, the team plans to enhance Clio to handle more complex tasks, like “find survivors” or “restore power,” moving closer to a human-like understanding of tasks.
eVinci
Westinghouse Electric Company is pushing forward with its groundbreaking eVinci nuclear microreactor. Drawing on space nuclear technolo-
measuring less than 10 ft (3 m) in diameter and capable of generating up to 5 megawatts electrical (MWe) with a core design that produces 15 megawatts thermal (MWth).
gy, this compact reactor has no moving parts and can be easily replaced for refueling, similar to swapping out a used gas cylinder.
As concerns about climate change grow, nuclear energy is making a comeback. Its zero-emission nature and capacity to produce substantial power make it well-suited to tackle many energy challenges.
However, the industry must address safety concerns—whether real or perceived—while also improving availability and reducing costs. Additionally, it needs to accelerate the typically lengthy construction timelines that have historically spanned several years.
Westinghouse’s answer to these challenges is the eVinci microreactor,
This compact unit can be produced in a factory instead of being built onsite and operates for more than eight years on a single fuel load. Once the fuel is exhausted, the entire reactor is deactivated, loaded onto a truck, and transported back to the factory for refueling or to be replaced with a new unit.
What distinguishes the eVinci from other small reactors is its lack of moving parts during normal operation and its independence from water or other coolant circulation.
It utilizes highly resilient TRISO (TRi-structural ISOtropic) fuel, which is composed of uranium enriched to 19.75% and sealed into pellets the size of millet seeds made from uranium, carbon, and ceramic materials.
These pellets are formed into small spheres, which are then packed into rods and placed in the core. This results in a fuel assembly that is exceptionally durable, resistant to heat and corrosion, and capable of producing a self-limiting nuclear reaction that cannot become uncontrolled.
In addition to the fuel rods, shutdown rods are included during transport to completely halt the nuclear reaction. A rotating drum must also be moved aside for the core to activate, and in an emergency, this drum automatically rolls back into position to safely shut everything down.
In summary, once operational, the reactor requires no moving parts to function, including for cooling. Rather than circulating water, it employs a solid-steel monolith to encase the core and absorb heat. Heat is then passively conducted away via alkali heat pipes, which utilize phase changes in the alkali metal to cool the reactor and convert the heat into electricity.
This design results in a compact and inherently safe reactor. Westinghouse asserts that the eVinci can be installed above ground in a relatively lightweight facility that occupies only about two acres (8,090 m²) and requires just a small staff for operations and security. The core’s size allows it to be shipped in standard containers by rail, barge, or truck.
Beyond civilian power generation, Westinghouse indicates that the eVinci is also ideal for powering remote areas, mining and drilling activ-
ities, industrial plants, district heating, hydrogen production, research facilities, military bases, and data centers. It can be configured for on-demand loads, enabling integration with wind and solar energy grids.
The company has submitted a Preliminary Safety Design Report (PSDR) for the eVinci microreactor to the Department of Energy’s (DOE) National Reactor Innovation Center (NRIC), marking a significant milestone for the reactor.
“This PSDR submission is a crucial step toward bringing the Westinghouse eVinci Microreactor into commercial operation,” stated Jon Ball, President of eVinci Technologies at Westinghouse. “We aim to deploy multiple eVinci microreactors globally by the end of the decade, and our strong ongoing partnership with INL and the Department of Energy is vital to our progress.”

A new study by physicists explores a common frustration: scheduling meetings. The central question is how challenging it is to find a time when everyone is available. As expected, the results weren’t encouraging.
“We wanted to understand the odds,” said Harsh Mathur, a physics professor at Case Western Reserve University. “Probability theory, which started with gambling, is just as relevant to scheduling.” The team used mathematical modeling to determine how the likelihood of scheduling a meeting decreases as the number of participants increases.
Their findings revealed that the number of potential meeting times to consider grows exponentially with more participants. “Initially, the project seemed like a joke, but this exponential growth highlighted how complex planning is, akin to major computer science problems,” Mathur noted.
The study also uncovered a tipping point where scheduling becomes nearly impossible with just four or five participants, depending on available timeslots. This sudden shift is similar to physical phase transitions, like ice melting into water. “It’s remarkable how scheduling complexity parallels phase transitions,” Mathur remarked.
Beyond scheduling, the study’s models have broader implications.
“Our sophisticated models could have wider applications,” Mathur said. Katherine Brown, co-author and Associate Professor at Hamilton College, suggests that these models could benefit any consensus-driven problem, such as international climate agreements. Ultimately, the study confirms what many already know: scheduling meetings can be a significant challenge. “Consensus-building is hard,” Mathur concluded.

HHSC Promotes Preventive Care for Breast Cancer Awareness Month
Georgia’s Six-Week Abortion Ban Violates Women’s Rights
The Texas Health and Human Services Commission is promoting breast cancer screenings for women during Breast Cancer Awareness Month. Women aged 40 to 74 should have a mammogram every two years, as recommended by the U.S.
Preventive Services Task Force.
The HHSC Breast and Cervical Cancer Services program offers free screening and diagnostic services for eligible uninsured and underinsured women, helping over 32,000 women last year. Women with incomes at or below 200% of the federal poverty level may qualify for these services.
Judge Robert C.I. McBurney ruled that Georgia’s LIFE Act violates women’s rights to make healthcare decisions and carry an unwanted fetus to term. He emphasized that until a fetus can survive outside the womb, the balance of rights favors the woman, reinforcing that her choices regarding her body and health are private.
The law’s six-week ban fails to serve a compelling state interest and infringes on equal protection rights by treating mental and emotional health risks differently. This ruling is a critical win for reproductive rights amid increasing state-level restrictions following the Supreme Court’s decision in Dobbs v. Jackson Women’s Health Organization.

Welcome back to Curiosity, where today we’re falling into one of the most fascinating and downright mysterious topics in all of physics—Black Holes. And as if black holes weren’t strange enough, we’ll also throw in Hawking Radiation, a mind-bending idea from the brilliant Stephen Hawking that suggests black holes might not be as “all-consuming” as we thought. Buckle up, because this trip through spacetime is going to be wild!
Picture a black hole as the ultimate gravitational trap—a region in space where gravity is so strong that nothing, not even light, can escape. This happens when a massive star collapses under its own weight at the end of its life cycle, creating a singularity, a point of infinite density. Surrounding this singularity is the event horizon, a boundary where escape becomes impossible. Cross that line, and you’re saying goodbye to the universe forever. Fun, right?
But here’s the kicker: while black holes sound like space vacuum cleaners, they don’t exactly suck in everything
around them. Objects have to get fairly close to the event horizon to feel its deadly gravitational pull. Farther away, black holes just act like any other massive object in space. So, no need to worry about the Milky Way getting gobbled up any time soon!
1. The Event Horizon: The Point of No Return
Imagine stepping into a black hole (not recommended), and once you cross the event horizon, you’re done for. Time and space distort beyond recognition, and in a process poetically named spaghettification, you’d be stretched into a long, thin noodle due to the immense gravitational gradient. It sounds like a cosmic horror show, but hey, at least you’d be part of an elite club—humans who’ve been spaghettified.
Not all black holes are the same. We have stellar black holes (a few times the mass of the sun), supermassive black holes (millions or billions of times more massive), and even mini black holes (hypothetically). The supermassive variety sits at the center of galaxies, including our very own Milky Way, where Sagittarius A*, a black
hole roughly 4 million times the mass of the Sun, holds everything together like the ultimate cosmic glue.
Thanks to Einstein’s theory of general relativity, we know that black holes can warp time. The closer you get to the event horizon, the slower time moves compared to the outside world. So, in theory, you could watch the universe evolve in fast forward while you’re near a black hole, but good luck getting out to tell the tale.
Stephen Hawking, one of the greatest minds in physics, made a groundbreaking proposal in the 1970s that black holes aren’t entirely black. In fact, they emit radiation—what’s now called Hawking Radiation. This idea turned everything we thought about black holes upside down.
Hawking Radiation arises from the strange world of quantum mechanics near the event horizon. In a nutshell, empty space isn’t truly empty—it’s buzzing with “virtual particles” that pop in and out of existence. Normally, these particle pairs annihilate each other almost instantly. But near a black hole’s event horizon, one of these particles might fall into the black hole
while the other escapes into space. The escaping particle becomes real radiation, and it appears as though the black hole is slowly leaking energy.
The kicker? Over incredibly long periods of time, Hawking Radiation can cause black holes to evaporate completely! This means that black holes are not eternal cosmic prisons—they have a shelf life. Mind officially blown.
Surprising and Fun Aspects of Hawking Radiation
1. Black Holes Can Shrink
Before Hawking’s theory, it was thought that black holes could only grow by consuming matter and energy. But Hawking Radiation suggests they can slowly lose mass and shrink. In theory, this means a black hole can “evaporate” over billions and trillions of years, leaving nothing behind—just a tiny pop at the end of its cosmic life.
2. Quantum vs. Gravity: The Ultimate Cosmic Smackdown
Hawking Radiation sits at the intersection of quantum mechanics (the study of the very small) and general relativity (the study of the very large). These two theories usually don’t play well together, and black holes are the arena where they clash most dramatically. It’s like a cosmic cage match be-
tween two heavyweight champions— Einstein’s gravity and the quantum world.
3. Information Paradox: A Black Hole’s Secret Keeper
Here’s the real brain-twister: If black holes evaporate, what happens to the information about everything they’ve consumed? Physics says information can’t just disappear, but black holes seem to break that rule. This is known as the black hole information paradox, and solving it could unlock the deepest secrets of the universe. It’s like the ultimate detective mystery— but on a cosmic scale.
Black holes might seem like distant, mind-bending phenomena, but they’re key to understanding the universe itself. They challenge our understanding of space, time, and the fundamental laws of physics. Plus, studying black holes and Hawking Radiation could one day help us develop new technologies, perhaps even allowing us to manipulate energy on unimaginable scales.
Black holes are the universe’s way
of keeping things exciting. Whether you’re fascinated by the mind-boggling concept of the event horizon or enthralled by Hawking Radiation’s ability to slowly “erase” these cosmic giants, there’s no doubt that black holes offer a never-ending supply of curiosity.
In a universe full of mystery, black holes are the ultimate puzzle, and with each discovery, they show us just how much we still have to learn about the fabric of reality itself. So, next time you look up at the night sky, remember— somewhere out there, a black hole is shrinking, ever-so-slowly radiating away, proving that even the darkest corners of the universe have more going on than meets the eye!
Do Relationships with Narcissists Work? Study Suggests Maybe
Despite common perceptions, not all relationships with narcissists lead to mental health issues. The study indicates that non-pathological narcissism doesn’t automatically harm partners’ well-being.
It’s crucial to differentiate between benign narcissistic traits and Narcissistic Personality Disorder. While navigating relationships with narcissists can be complex, establishing boundaries is vital to maintain personal health and happiness.
You deserve a life filled with safety, happiness, and healthier relationships. While preparing daughters for marriage, it’s essential to balance resilience with the courage to leave when necessary, as toxic relationships can lead to serious health issues.
Recognizing warning signs like extreme reactions or controlling behavior is crucial. Ignoring threats of harm can have tragic consequences, and it’s vital to prioritize safety and emotional health over fear of judgment or financial instability. Sometimes, the bravest choice is to leave a harmful situation behind.
“Roommate syndrome” occurs when a relationship shifts from partnership to cohabitation, leading to emotional disconnection. Partners may lead separate lives, lack intimacy, and avoid meaningful communication, which fosters feelings of isolation. It’s essential to recognize these signs and consider whether the emotional bond has weakened, indicating a need for reflection and potential change.
