Genes for Africa: tailoring treatments to match diversity

CSIR and UCT researcher Dr Janine Scholefield has been making waves with her research into the genetic origin of adverse reactions to antiretroviral medication. Lab Management & Science spoke to her about the exciting world of stem cells, how genome engineering could create immunity to HIV and how new drugs don’t take Africa’s genetic diversity into account. When explaining why stem cell research is important,

“What we need to understand about Layla’s case,” Dr Scholefield said, “is that the combination of genome engineering and cellular therapy is going to start curing things that were completely resistant to any kind of therapy before.” As a geneticist, Dr Scholefield studies the way genes control cells and particularly how they can adversely affect cells and cause disease. Increased knowledge of these processes helps scientists to develop novel treatments based on a deep understanding of cell processes no one imagined possible a mere decade ago.

Genome engineering in a nutshell The modern science of genome engineering is based on the understanding that sequences within your DNA dictate the proteins your body makes. Any changes to the coding sequences of your DNA changes what your proteins do, or in a worst-case scenario knock that sequence out of your DNA and not form any proteins at all. Genome engineering works by introducing nucleases that act like molecular scissors, prompting a massive double strand break in your DNA helix. “Cells can repair the damage caused by nucleases in one of two ways,” Dr Scholefield said, “either by simply grafting the two ends of the helix together, which is not always optimal, or by guiding a new piece of DNA into the gap created by the nuclease, perhaps by using Cas9, the basis of CRISPR technology.” The second approach has delivered the best results so far, potentially providing cures for monogenic diseases such as cystic fibrosis and sickle cell anaemia. Dr Scholefield, who completed a PhD on a degenerative disease called spinocerebellar ataxia, works for the CSIR and UCT as a lecturer and specialist in stem cell biology. “Understanding how mistakes in our DNA cause disease is a big part of a geneticist’s Dr Janine Scholefield, CSIR senior researcher w w w.lm s m a g a z i n e .c o. z a

apparent that some people, especially in the African population, are more susceptible to disease than others,” she said. Moreover, our genetics dictate how different people react to drugs. She believes the key to understanding why this happens relates to mutations in our liver genes, especially the ones that metabolise drugs. “In a Finnish population one of these mutations, called the T allele, is present in only 16% of the population, while in a Kenyan population it is present in 36%,” she pointed out. “If you have the T mutation you can’t metabolise your antiretrovirals.” For years, people who don’t possess the

Brown’s cure appears to have come about when he was given a bonemarrow transfusion from an individual with the CCR5 mutation. “The incredible thing about the CCR5 mutation is that we just need to knock it out in the lab to

Beer, grub and machines at fdt Africa 2018 This year’s Food and Drink Technology Africa (fdt Africa) event, organised by Messe München, brought together 111 exhibitors and 1 600 participants from 81 countries. Cue furious networking between the packaging, quality control and manufacturing industries and lots, lots, lots of beer. The team from EcoLab presented advanced testing and hygiene technologies.

Gallagher Convention Centre in Midrand was abuzz with the cream of the food and beverage industry from 4-6 September. Representatives from the entire process chain of the industry were present. There was also plenty of beer. The event played host to the annual Institute of Brewing and Distilling (IBD) African Beer Awards, where Joburg’s own Mad Giant Brewery took home the overall prize for their excellent Killer Hop Pale Ale. Microbreweries and the craft beer market seemed to be a focus for many of the exhibitors at the event, many of whom displayed scaled-down distilling and brewing machines specifically designed for the craft beer market. “SA’s craft beer market hasn’t reached the size of the ones in Europe or the United States, where some craft brewers are competing with major beverage companies,” said Apiwe NxusaniMawela, owner of Brewsters Craft, “but the potential for growth is

definitely here.” There are currently over 200 craft microbreweries in SA and the local scene has even started attracting tourists of late. The global craft brewing industry is expected to reach a market value of R7.4tn by 2025, but the SA market is as yet underdeveloped. This is doubly unfortunate because SA is one of the largest markets for beverages in the Southern hemisphere. A whopping 11 billion litres are sold in SA annually. Not only does this represent an opportunity for South African craft brewers, it also means there is a huge gap in the market for locally produced manufacturing, processing and packaging technology. SA is currently forced to import most of the machinery it needs, as witnessed by the Chinese, German, Swiss and Italian machinery suppliers present at the expo. According to data from Euromonitor International, the value of these imports amounted to R31bn over five years, with 80% of this money going to Germany and Italy. As SAP Italia sales representative Guido Ricci pointed out, the craft brewing market in the developing world is potentially larger than the

he said, “Probably because there is still a lot of ignorance about the potential size of the industry.” In a social media age, beverage sales are being driven as much by good local marketing as they are by brand recognition.

Labs involved in food, beverage diagnostics Many of the companies represented at the expo focused on quality control and diagnostics for the food and beverage industry. Often, this involves using high-tech equipment in a controlled lab setting to ensure that foods and beverages meet the requisite specifications for export or domestic use. According to Dr Phiyani Lebea, CEO of local agricultural diagnostics firm Ralejelete Holdings, it is extremely important for producers to meet quality criteria if they want to be taken seriously internationally. “Food exports come with a host of stringent regulations, depending on which country you export to,” Dr Lebea said. “Sorting through this information and ensuring that clients conform to all specifications is a growing industry among lab technicians such as ourselves.” In 2016, agricultural exports alone contributed 12% to total exports for a total of R135 billion. Thanks to the BRICS arrangement, new export opportunities in Russia and China could see those numbers increase substantially, which will create more opportunities for local testing labs.

One of the most encouraging takeaways from the expo was the amount of food companies who are opting to produce products. There has been growing consumer demand for healthy and additive-free food products, following years of negative publicity about the adverse effects of substances like MSG, aspartame and sodium nitrite. Suppliers such as Cape Town-based Sphere Foods are providing products that are 100% naturally derived and are having trouble keeping up with demand. Even some firms in the packaging industry are displaying a commitment to green processes. Bloemfontein-based Sheet Plastic, which specialises in extruded plastic sheeting, is trying to produce plastic products that can be reused by industry and using recycled materials to do so, thereby lowering the local plastics footprint considerably. “It is very important that local companies start looking at environmentally friendly packaging solutions,” said Sheet Plastic’s managing director, Van Chen. “The importance of trying to maximise green processes early on cannot be overemphasised.” Next year’s event will be a joint expo with Lab Africa, fdt Africa and IFAT Africa exhibiting together for the first time. Whether there will be triple the amount of beer remains to be seen. M

Mysterious deep space light flashes could be neutron stars or aliens

Largest ever brain-aging study points finger at schizophrenia, weed The largest study into brain aging ever conducted has raised concerns about the aging effects of psychiatric disorders and substance abuse. The study evaluated 62 454 single photon emission computed tomography (SPECT) scans from more than 30 000 individuals ranging in age from nine months to 105 years old. SPECT is a nuclear medicine technique that measures blood flow to tissues and organs, in this case the brain. It is hoped that better understanding of factors that lead to premature aging in the brain can be used to create treatments that prevent or reverse brain aging. The top cause of brain aging was found to be schizophrenia, which accelerated the aging process by as much as four years. Surprisingly, the second most severe accelerant was regular marijuana use, which aged the brain 2.8 years on average. ADHD, bipolar disorder, anxiety and alcohol abuse were key factors in brain aging, as was being male.

A mysterious burst of light flashes in deep space puzzled astronomers last year, and now researchers with the Breakthrough Listen programme are suggesting it might be a sign of alien life. While emissions from neutron stars were suggested as a possibility for these flashes, known as fast radio bursts (FRBs), there is as yet no indication that this is the case. Breakthrough Listen, the world’s largest and most wellfunded organisation searching for extraterrestrial life, believes the anomalous nature of the flashes indicates an intelligent origin. For one thing, light flashes in deep space do not tend to be once-off events. These, which emanated from FRB 121102, a galaxy three billion light years away, occurred 93 times within the course of a single day. Researchers believe this may indicate concerted activity by an advanced civilization, but with the very nature of FRBs still a matter of debate, the truth remains out there.

Solar panels could turn the Sahara green and power the globe

A proposal to cover the Sahara desert with solar panels and windmills could potentially generate enough power to provide for the entire planet’s energy needs several times over. A welcome side effect will be reversing desertification and increasing the amount of greenery in the Sahara. The process of desertification has increased the size of the Sahara by 10% in the last 100 years, but scientists believe that solar panels and wind farms will lower air pressure in the Sahara, causing winds from surrounding regions to flow there and rise due to the increased heat of the soil. This increased concentration of air will lead to higher concentrations of moisture in the air when it rises and eventually lead to rainfall and the return of vegetation to the region. Critics of the proposal have pointed to political instability in the Sahara as the major factor preventing its implementation.

Programme makes fake footage indistinguishable from reality

A deep video portrait software programme has brought the concept of the Matrix one step closer to reality by altering existing footage in such a way it can’t be distinguished from reality. This was revealed in a presentation by researchers from the Max Planck Institute for Informatics during the annual SIGGRAPH conference in Vancouver. Essentially, the programme allows you to take any piece of footage and seamlessly model your own facial expressions onto the face of someone in the video. Coupled with audio manipulation software, this creates the potential for the production of fake videos in which users can make famous (or non-famous) folks say anything they would like them to. According to the researchers’ presentation notes, “Our novel deep video portrait approach enables full control over a target actor by transferring head pose, facial expressions and eye motion with a high level of photorealism.” So if you start seeing videos in which Donald Trump talks about his past life as a walrus, it’s either fake – or just 2018. w www.lm w w.lm s m sam g aazgianzei.c n eo..czo. a za

L AB SP OTL IGHT Research activities SANAE IV consists of three linked, double-story modules, each 44 metres long. A-block, the southern module, has a medical facility, two physics labs and a wet lab for the testing of fluid samples. Current research projects being undertaken include a study into biocomplexity and numerous cosmological projects, as well as a study on landscape and biosphere interactions in Antarctica. A-block is where most of the scientific activity takes place and B-block is mostly a recreation and accommodation facility. C-block, the northernmost part of the base, features a gym and hanger facility, as well as North West University’s (NWU) expensive neutron monitors. These are maintained by a team deployed from NWU and scan the skies to monitor the intensity of cosmic rays. A particular focus of the neutron monitors in C-block is the study of solar flares and their accompanying coronal mass ejections. The neutron monitors work in an interesting way. Firstly, a tube filled with an easily ionisable gas is kept at a high potential (2800V). When a high-energy neutron passes through the tube and collides with the gas molecules, the molecule is hit with enough energy to release electrons from its valence structure, leaving a positively charged ion and an electron. The electric field created by the large potential prevents the ion and electron from recombining and pulls each one to its opposite polarity. The electrons reaching the anode will generate a pulse proportional to the energy level of the particle it collided with. These pulses are then recorded as events. Another recurring research project at SANAE IV is the operation of high-tech ground-penetrating radar systems to look beneath the ice sheet. This is an important part of the ongoing monitoring of the continent’s response to climate change and provides insight into the changing patterns of ice accumulation on the continent and the

Hard work but rewarding According to NWU’s Cobus van der Merwe, the technician currently responsible for maintaining the neutron monitors, the workload at the base gets to be quite intense. “You would think that spending a year in the most remote place on Earth, with nothing to distract you but you, will leave you with countless hours to fill,” van der Merwe said. “However, this has not been the case.” Even when not engaged in scientific research, team members have to perform chores around the base, in van der Merwe’s case bulldozing ice out of the way to create a parking lot for SANAE IV’s vehicles. Everyone who spends an extended period of time at the base notes that, although circumstances are often difficult, the experience has a lasting positive effect. “This continent is hostile but beautiful,”

communications engineer Hloni Rakoteli said. “You see nothing for miles except the pure white and ridges here and there.” Electrical engineer Bo Orton, meanwhile, emphasised that one must respect the elements in Antarctica or risk being overwhelmed. “You quickly learn here that the weather is king and most things are related to how the weather is looking,” Orton said. “You have to appreciate how fast and powerful the wind can be and how low the temperature can drop. If you don’t respect the weather here, the wind will flick you off Antarctica’s shoulder as you would a fly and your ego will vanish with you.” Most of the SANAE IV scientists hope to go back home with plenty of stories to tell their loved ones. Nonetheless, the overwhelming nature of the experience often leaves Antarctic visitors at a loss for words. “I already know now that when I get home and people ask how it was, all I’ll be able to say is ‘you had to be there’,” Orton noted.

Caprids, corvids and cockroaches Goats prefer happy faces

Goats often get a bad rap, seen as stubborn, unidimensional sheep stand-ins. But those who spend time with the bearded quadrupeds testify to the unnerving emotional complexity they display. A new study appears to confirm this view by demonstrating how domestic goats prefer smiling human faces over angry ones. After being hand-fed a few times, the goats were led away while the researcher who fed them was replaced by two pictures, depicting that researcher either smiling or angry. The goats overwhelmingly headed straight for the smiling picture – but only if it was on the right, since goat brains process negative emotions in the left hemisphere. Evidence suggests that prolonged exposure to humans sensitises animals to our emotions, as demonstrated by previous studies of dogs and horses.

Clever crows and their mental blueprints

Long seen as the brainiacs of the bird kingdom, crows are renowned for their feats of memory, including the ability to remember human faces for up to five years. But it seems the clever corvids are capable of even greater craftiness: the ability to engineer tools from a mental image. Quite a lot of mental gymnastics is involved in such a feat. First a solution to a problem must be envisioned, in the shape of a tool, then the optimal way to build the tool must be determined. Crows are capable of all this, as demonstrated by a recent study in which a number of New Caledonian crows were trained to feed cards of a particular size into a slot to get birdy treats. When the cards were taken away and replaced with sheets of paper, the crows proceeded to tear the paper into strips matching the required card sizes and feed these into the slot instead. Essentially, they were creating tools without a reference point – the definition of invention.

Search-and-rescue cyborg roach

Credit: the Dutta Lab

Unless you’re an entomologist, you probably don’t have many fond words for the common cockroach – which is too bad, because they could save your life one day. A team from the University of Connecticut has created what is best described as a cyborg roach, strapping a neuro-controller microcircuit to the insect’s back and attaching wires from the circuit to its antennal lobes. Sending an electric signal to the right lobe will make the insect swerve left, and vice versa, allowing whoever controls the signal to steer the cockroach. The microcircuit also has a Bluetooth receiver, allowing smartphone app control of the cyberroach. It is hoped that cockroaches outfitted in this way can be used in search-and-rescue missions to find survivors under rubble and other hard-to-reach places.

Space: the final battlefield? Now that official US pronouncements point to China and Russia’s activity in space as a prime reason to secure its own space assets, are we in the midst of a new space race? One in which holes mysteriously appear in space stations and battles are fought not between armies of gun-slinging troops but between ground-based systems and the satellite imaging tech above. Lab Management & Science investigates… On Thursday 9 August, US Vice President Mike Pence took to a podium at the Pentagon and announced the creation of a Space Force, a new branch of the US military hat would deal with threats from outer space. According to Pence, this was necessary because of a space environment that was ‘crowded and adversarial’, adding that, “Our adversaries have transformed space into a warfighting domain already.” $8bn was to be allocated to space security systems over the next five years. While the announcement was met with puzzlement by pundits and the public alike – not least because the Space Force is rumoured to be one of President Donald Trump’s pet projects – many have pointed out the merit of the idea.

22 

LMS  Issue 4 | 2018

For one thing, the possibility of a space technology arms race between the US, Russia and China has been the talk of the town in Washington DC for some time. The militarisation of space is a constant feature of global defence strategy, and recent quantum leaps in weapons technology by the Russians and Chinese have placed the US on edge. This led General John Hyten, the general in charge of US space operations, to declare that the Chinese and Russians are, “Building those capabilities to challenge the United States of America, to challenge our allies, and to change the balance of power in the world.” The announcement of a Space Force came a few months after Russian president Vladimir Putin unveiled a series

of incredibly high-tech superweapons that he claimed are decades of advance of Russia’s adversaries. The Chinese, meanwhile, have been perfecting satellite-killing technologies such as ground based direct ascent missiles, signal jammers and laser weapons that can dazzle or blind satellites. This is a grave threat to high-tech modern militaries that have incorporated satellite imaging and intelligence as an essential part of their arsenals. Drones, air strikes and ship or ground-based artillery, three of the mainstays of Western military interventions in Afghanistan, Iraq and Syria, would be crippled by the sudden loss of imaging capability. Last year the US’ Worldwide Threat Assessment of the US Intelligence w w w.lm s m a g a z i n e .c o. z a


SPACE NE WS Community directly mentioned Russia and China’s space militarisation efforts. “Foreign countries – particularly China and Russia – will continue to expand their space-based reconnaissance, communications, and navigation systems in terms of the numbers of satellites, the breadth of their capability, and the applications for use.” The document also calculated that Russo-Chinese satellite-killing capabilities would reach ‘initial operational capability’ in the next few years.

History of space militarisation Space has been a realm of wonder in the popular imagination for a long time, but it has always been a military frontier from a policy perspective. The first steps towards space militarisation were taken by the Germans before and during the Second World War, with much of the scientific groundwork for space technology originating from the Nazi V1 and V2 rocket programmes. The V2, in fact, became the first man-made object in space during its test flight in 1942. After the war, the US and the Soviets competed to smuggle as many Nazi scientists out of Germany as possible under secret programmes such as Operation Paperclip and the Soviet Operation Osoaviakhim. One of the scientists ‘appropriated’ in such a way was former SS man Werner von Braun, who became a bigshot at a newlyformed US agency called NASA. The race to place the first man on the moon was merely one of the more public events in the Space Race. Satellite technology meant that countries no longer needed to funnel valuable intelligence capabilities to scouting or other charting activities, since the ‘eye in the sky’ could now relay exact information about troop movements and other ground activities at the touch of a button. Ronald Reagan’s infamous Star Wars programme (officially called the Strategic Defence Initiative) was not a success, but historians now believe it contributed to the fall of the Soviet Union by forcing the Soviets to allocate more spending to counter the potential threat of such a programme. The creation of dedicated space commands by the major players in the current space race preceded the end of the Cold War. Currently, space defence technologies focus on aerial reconnaissance, the collection of image intelligence (IMINT) via super high resolution photography, and implementation channels for high w w w.lm s m a g a z i n e .c o. z a

speed communications systems that would allow for a real-time view of the battlefield. Using this technology, a soldier could theoretically access satellite imagery to view troop positions a few blocks away.

 The US calculates

that Russo-Chinese satellite-killing capabilities will reach initial operational capability in the next few years.  Putin on the pressure While the US is the acknowledged global leader in space, the Russians have eagerly set to work undermining that position. The recent spate of superweapons announced by the Kremlin is purported to have Washington insiders on edge. They include an intercontinental ballistic missile system that Russia says is invulnerable to defensive measures. Whether this is hype or not remains to be seen, but the establishment was again up in arms in mid-August when high-ranking State Department members spoke publicly about the ‘abnormal’ behaviour of a particular Russian satellite, which might indicate that it is a weapons platform. Publicly, both Russia and China have declared that space should be a peaceful domain, although evidence clearly suggests that even technologies with peacetime applications such as satellites are being designed with the potential for conflict in mind. While this may just appear to be prudence to some, the US is taking it as an unspoken declaration of war. Perhaps this has something to do with rumours rife on Russian media that the hole that recently appeared in the Soyuz spacecraft was drilled by an American astronaut.

People’s liberation space cadets The People’s Liberation Army of the Republic of China is one of the most formidable militaries in the world, numbering over 2.3 million souls and 7 700 tanks, for a start. But the major Western powers are less concerned about China’s tanks than the occasional blip it sends into space, as witnessed by the Washington panic when Beijing

blew up one of its own satellites in 2007. As Mike Pence has it, it was, “A highly provocative demonstration of China’s growing capability to militarise space.” Their direct ascent missile capabilities have the Americans worried. A 2013 test of the Dong Neng 3, China’s premier high altitude missile, reached a height of 30 000 kilometres, geosynchronous with most Western satellite orbits. The problem with recognising China’s increasing space militarisation for what it is becomes labyrinthine when one has to sort civilian programmes from military initiatives posing as civilian ones. Take their recent space laser announcement. When scientists from China Air Force Engineering University proposed a space-based laser system, it was as a means of clearing the 18 000 objects that orbit Earth and endanger space assets. But Western media was noticeably sceptical about the claim, and perhaps rightly so, since Chinese officials have admitted to preferring dual-use space technology that could be useful during both war and peace.

Space destiny Things seem to be heating up as we approach 2019, with Russia and China collaborating to present a gigantic military exercise at the Vostok 2018 event in September. The prospect of collaboration between the number two and number three largest militaries in the world will only spur the US on to produce newer and better defence measures at a more rapid rate. At least, as the Russians noted, the soldiers who played opponents during the event weren’t wearing NATO or US uniforms. When the US stages wargames, they typically dress the opposing side in PLO uniforms. The Pentagon very recently released a memo outlining plans to get the Space Force up and running by 2020. The effort, which will be overseen by Deputy Defence Secretary Patrick Shanahan, will see the creation of a US Space Command, a branch of the military exclusively dedicated to space warfare, before the end of 2018. The stakes are extremely high and not helped by pronouncements implying that the US concept of manifest destiny applies to the stars. “Our destiny, beyond Earth, is not only a national identity but a matter of national security,” Trump said in June. “When it comes to defending America, it is not enough to merely have an American presence in space.

Laboratory Technology and Diagnostics

Sophisticated and precise analyses require precisely adjusted, certified volumetric solutions. Whether you’re titrating reducing or oxidizing substances, acids, bases or complexing reagents in either aqueous or non-aqueous solutions: Merck Millipore offers the right solutions for every application.

• Certified and consistently high level of quality • Innovative and optimum packaging systems • Reliable and precise analyses

Precision and quality Like all Merck Millipore products, Titripur® volumetric solutions are subject to stringent manufacturing and testing requirements. From the selection of the raw materials and packaging on up to quality control, the highest demands are placed on purity and quality.

BE PART OF THE NO.1!

Volumetric solutions Under the brand name Titripur®, Merck Millipore offers you first-rate volumetric solutions. Volumetric solution described in the European and the US Pharmacopeia are in accordance with the reagents chapter of the Pharmacopeia. For each solution, titer determination is performed under optimum and standardized conditions. All volumetric solutions are traceable to certified secondary reference materials, which in turn are directly traceable to standard reference materials from the NIST. Consequently, all volumetric solutions from Merck Millipore are directly traceable to NIST standard reference material.

Volumetric standard [V.S.] Volumetric standards are used for the standardization – titer determination – of volumetric solutions and for the qualification of the titration system. Influencing factors such as temperature, instrument variances, different methods of handling, weighing errors etc. and the volumetric solution itself can impact the titration result. To compensate for these factors, titer determination under working conditions is necessary in the respective laboratory. Secondary standard reference materials for titration are traceable to standard reference material from NIST.

Far-out news from the edges of science Soldiers now pilot drones with their minds

Our sci-fi future is approaching far quicker than predicted, and few organisations seem as hell-bent on hastening it as DARPA, the US Defense Department’s completely not-scary research division. Building on research from three years ago that allowed a paralysed woman to steer an F-35 fighter jet in a flight simulation, DARPA has developed a neuralcomputer interface which allowed a paralysed volunteer to control multiple drone craft in a simulator simultaneously. The volunteer, known as Nathan, controls both the flight paths and actions that the drones take while receiving detailed feedback signals from them. The drones can notify Nathan of threats in the vicinity and recommend courses of action based on real-time intelligence appraisals. DARPA claims to have spent a number of years refining the technology and hopes to achieve a roll-out soon. Brain-computer interfaces are becoming increasingly high-tech and are appearing more often in the private domain. Elon Musk, the SA-born tech pioneer, has announced that his company, Neuralink, will have developed a commercially available interface within the span of a year.

Digital teacher educates Kiwi kids about renewable energy

Learners at a primary school in Wellington, New Zealand, have been treated to the first ever lesson by an AI teacher. Will, a software programme that appears to students as a face on a screen, interacted with learners and answered their questions about renewable energy such as wind and solar power or geothermal heat. Created by New Zealand AI company Soul Machines, Will can be run on any number of devices such as laptops or smartphones, allowing students to be taught in small groups of two or three. Will is capable of responding to questions posed by learners and quizzes them on topics covered. Common questions include how long sunlight takes to reach Earth and how tall a wind turbine is. Students were positive about their experiences with Will, lending weight to futurist predictions that AI could replace teachers entirely as early as 2027.

Scientist claims Earth made of blueberries would turn into jam Sometimes thought experiments are worth engaging in simply for the joy of thinking involved. At least, that’s what we think motivated computational neuroscientist Anders Sandberg, a research fellow with Oxford’s Future of Humanity Institute, when he published a paper outlining what would happen if Earth turned into a giant ball of blueberries. Sandberg begins by assuming that the blueberries that replace Earth are of the big, thick-skinned variety, not the wild, thin-skinned type. It is unlikely that the blueberries will fit perfectly into each other, so the space between them would fill with air, which would reduce gravity on the surface significantly and cause humans to experience an 87 percent drop in body weight. Meanwhile, the air between the blueberries would be forced outward as gravity squishes the berries towards the planetary core. Everything would heat up to the point where the planet’s surface becomes boiling blueberry jam and steam, which would form a quasi-atmosphere. Lastly, the moon would hurtle off into space, released from our gravity.

Anti-ageing pill could extend lifespan to 150 years

A breakthrough by researchers from Harvard and the University of New South Wales has demonstrated how the human lifespan could be extended to 150 years and could allow people to regenerate their own organs as early as 2020. The technique is based on reprogramming cells and utilising the anti-ageing activity of nicotinamide adenine dinucleotide (NAD), a coenzyme found in all living cells. NAD plays a significant role in generating energy within the body. The study’s lead researcher, Harvard’s Professor David Sinclair, believes that the treatment, which will be available in a pill form, could even reverse paralysis and hair loss. He claims to have selfmedicated with the treatment and experienced a 24-year drop in biological age, reversed his sister’s menopause and turned his 79-year-old father into an avid white-water rafter. Clinical trials have yet to start but it is hoped the treatment could reach the market within five years.
