Scientists have figured out how to stop the common cold in its tracks

We’re still a long way off developing new drugs to combat them, but scientists have finally cracked the code used by a major group of virus to spread infections such as the common cold, Ebola, hepatitis C, HIV, and polio around the body. This newly discovered code has been hiding inside the sequence of ribonucleic acid (RNA) – a nucleic acid involved in the coding, decoding, regulation, and expression of genes – that makes up the genome of the single-stranded … Continue reading

What happened to the low-carb diet fad?

Dr-Robert-Atkins

For many people, the low-carb diet went the same way as its principal advocate, Dr Robert Atkins, who died in 2003. At the time, the popularity of the diet prompted warnings from, among others, the American Medical Association that the low-carb regime was ‘potentially dangerous’. Most controversy surrounded the effectiveness of the diet and the long-term health effects, which became the focus of scientific studies. The results now emerging suggest the original concerns were largely misplaced. The low-carb diet appears … Continue reading

Researchers have found a DNA “clock” that predicts how long you’ll live

And they can measure how quickly it’s running down. An international team of scientists has found a way to predict how much time you have left – by comparing your actual age to your biological age, a number worked out by measuring chemical changes to your DNA. The difference between these two numbers can be used as a DNA “clock” to estimate someone’s lifespan, the researchers have discovered. And, we’re sorry to tell you this, but if your biological age … Continue reading

Penta-graphene, a new structural variant of carbon, discovered

Researchers at Virginia Commonwealth University and universities in China and Japan have discovered a new structural variant of carbon called “penta-graphene” – a very thin sheet of pure carbon that has a unique structure inspired by a pentagonal pattern of tiles found paving the streets of Cairo. The newly discovered material, called penta-graphene, is a single layer of carbon pentagons that resembles the Cairo tiling, and that appears to be dynamically, thermally and mechanically stable. “The three last important forms … Continue reading

Breakthrough pill can CURE diabetes

diabetes

Diabetes could be cured by simply taking a pill that “rewires” the body, researchers have claimed. Handing hope to the millions of sufferers in the UK, the new study suggests that a “probiotic pill” – one containing live bacteria – can radically reduce blood glucose levels. In experiments researchers discovered that using a pill containing common bacteria found in the human gut can shift the control of glucose levels from the pancreas to the upper intestine. It is believed that … Continue reading

New mathematical theory may explain patterns in fingerprints, raisins, and microlenses

As a grape slowly dries and shrivels, its surface creases, ultimately taking on the wrinkled form of a raisin. Similar patterns can be found on the surfaces of other dried materials, as well as in human fingerprints. While these patterns have long been observed in nature, and more recently in experiments, scientists have not been able to come up with a way to predict how such patterns arise in curved systems, such as microlenses. Now a team of MIT mathematicians … Continue reading

World-first evidence suggests that meditation alters cancer survivors’ cells

For the first time, scientists have found clear biological evidence that meditation and support groups can affect us on a cellular level. We’re often told that being happy, meditating and mindfulness can benefit our health. We all have that one friend of a friend who says they cured their terminal illness by quitting their job and taking up surfing – but until now there’s been very little scientific evidence to back up these claims. Now researchers in Canada have found … Continue reading

About That Huge Discovery Last Year About the Young Universe…

Well, this is disappointing. A team of astronomers announced last year that they thought they had strong and direct evidence for cosmic inflation in the extremely early Universe. But, after follow-up analysis, it turns out the evidence is far weaker, and it appears inconclusive one way or the other. Bummer. OK, so what’s the scoop? First, here’s the announcement from last year when it was thought that the evidence was really good. The details are there. But here’s a summary: … Continue reading

Sweden Invents a Revolutionary Anti Bullet Wall

Saab’s Soft Armour system offers protection against ballistic penetration up to NATO 7.62 mm AP ammunition (STANAG level III). The system is a box concept filled with hard ceramic balls. The system is especially designed to enhance survivability and can be fitted to any structure prior to missions, or even retrofitted to existing structures in operational theatre. A unique ceramic material protects against ballistic penetration. Soft Armour is a patented ballistic protection technology that provides security for people in vulnerable … Continue reading

Black holes do not exist where space and time do not exist, says new theory

The quintessential feature of a black hole is its “point of no return,” or what is more technically called its event horizon. When anything—a star, a particle, or wayward human—crosses this horizon, the black hole’s massive gravity pulls it in with such force that it is impossible to escape. At least, this is what happens in traditional black hole models based on general relativity. In general, the existence of the event horizon is responsible for most of the strange phenomena … Continue reading

New Technique Reverses Aging By Decades In Cultured Human Cells

Scientists from Stanford Medical Center have devised a technique for extending the length of human telomeres. It’s a breakthrough that could eventually result in therapies to treat a host of age-related diseases, including heart disease and diabetes. It could also result in longer, healthier lives. Telomeres are those critical protective caps located on the tips of chromosomes. Think of them as those protective pieces of plastic on the ends of your shoelaces. Without them, the tips basically fall apart, which … Continue reading

Why wormholes (probably) don’t exist

worm hole

Sometimes you’ll hear wormholes referred to as “Einstein-Rosen bridges”, referring to a 1935 paper by Billy Bob Albert Einstein and Nathan Rosen. John Archibald Wheeler and his colleagues did a lot of work on wormholes in the 1950s and ’60s, but their real entrance into the popular imagination came through Carl Sagan’s novel Contact. Through correspondence with gravitational physicist Kip Thorne, Sagan worked out a science fiction device: alien technology enabled the opening of a temporary wormhole between Earth and … Continue reading

Newly discovered ‘Super Saturn’ has colossal ring system

This is the first planetary ring system discovered outside the Solar System, and it’s got a diameter roughly 200 times larger than Saturn’s. Astronomers have found a planetary ring system with such enormous proportions, it makes Saturn’s rings look puny. The rings have formed around a young, giant exoplanet called J1407b, and they’re the first of their kind to be found outside our Solar System. The rings were first discovered in 2012, thanks to a team led by Eric Mamajek … Continue reading

Harnessing data from Nature’s great evolutionary experiment

deskarati dna

There are 3 billion letters in the human genome, and scientists have endlessly debated how many of them serve a functional purpose. There are those letters that encode genes, our hereditary information, and those that provide instructions about how cells can use the genes. But those sequences are written with a comparative few of the vast number of DNA letters. Scientists have long debated how much of, or even if, the rest of our genome does anything, some going so … Continue reading

The unique geology of Macquarie Island

macquarie island

Macquarie Island is located in the south-west Pacific Ocean, between Australia and New Zealand, and officially belongs to the Australian state of Tasmania. The island is tiny, only 5 km (3.1 mi) wide and 35 km (21.7 mi) long, covering a total area of 128 km2 (49 sq mi). It is a unique place: it is the only sub-Antarctic island to be fully oceanic in origin, and it is the only known site on Earth where an ophiolite complex is … Continue reading
