One of the most famous chemistry experiments of the last century was the ‘primordial soup’ project initiated by Stanley Miller. The chemist wanted to see what would happen if you mixed methane, ammonia and hydrogen – all substances readily available on Earth before life began – and zapped them with electricity, to create a phenomenon analogous to […]
I’m not sure what’s on with Stephen Hawking and his pessimistic view of the world. He’s been known for audacious, panic-inflicting claims like the world is going to be destroyed either by aliens or artificial intelligence, all if we don’t destroy ourselves in the meantime since humans only have 1,000 years left on this planet […]
Occasionally we’re hit by fever. Nobody likes it, most sane people actually hate it, but it’s important to note that it’s an important part of the healing process. Fever is a result of the immune response by your body to foreign invaders like viruses, bacteria, fungi, drugs, or other toxins. Research showed that it is triggered […]
Patients with hemophilia are often forced to live in a bubble. Even the smallest cut can cause significant blood loss, and often times these minor accidents can also cause internal bleeding that affects organs and threatens life. Some treatments have proven effective at keeping hemophilia at bay, at least to a degree, yet some groups […]
In an attempt to further out understanding of cell deformation and mechanics, researchers at the Technische Universität München (TUM) have built an artificial cellular model that can change its shape and move on its own. Cells are complex biological objects that exhibit sophisticated metabolic functions. Primordial cells, however, were much simpler in design: just a […]
There aren’t that many people who imagined that in only a couple of years we’d see smartphones with 40MGpx cameras. Amazingly as that may sound, manufacturers are nearing a stand-still as far as optics miniaturization is concerned and even so, high end camera phones don’t come near the quality of a dedicated optical hardware. A […]
Like most developing nations, India is burning a lot of coal to catch ground. As always the case with compromises such as these, economic growth comes at the expense of the environment. Pollution in Delhi, the capital, has reached levels comparable to Beijing, which is when you know you’ve hit a new low. A new study […]
Some atoms are more stable than others, and the same goes for their isotopes – elements that have the same number of protons in the nucleus, but different number of neutrons. For instance, some decay in a trillionth of a second, while others can live on for billions of years. Actually, using isotopes (thorium and […]
We often report how many species around the world are becoming extinct, but it’s heart warming to report from time to time that some conservation efforts really do work. For instance, a new report found that Blue whales (Balaenoptera musculus), the largest animals on Earth, have steadily increased in population around the Californian waters to the […]
Swiss scientists from the University of Bern demonstrated a new device that essentially generates electrical power from the mechanical energy of heartbeats.
A group of neuroscientists have achieved what some might believe strictly belongs to the realm of science fiction – they’ve successfully transmitted a message relayed by the brain of a person to another directly; no voice, no video, no sound, no text. The information was fed directly to the brain. If that wasn’t enough, the […]
A newly found superdinosaur Dreadnoughtus schrani, is the largest known land animal for which mass can be accurately calculated, a recent study concluded. The giant speciment, which isn’t even fully grown, probably measured 85 feet long and weighed about 65 tons. The name literally means “fear nothing”, and the dinosaur has already been nicknamed Dread. It is named […]
Our sun is but a tiny speck of light among billions, part of the spiral galaxy we familiarly call the Milky Way. That in itself makes us puny humans feel extremely humble, but things get really out of proportion when you zoom out. Galaxies on their own turn congregate in the hundreds or even thousands, […]
A new study analyzed the data from nearly 50 trials including about 7,300 individuals. Significant weight loss was reported with every low-carb or low-fat diet, with very small differences between them. This indicates that obese patients should be recommended any healthy diet they are most likely to keep up. Weight loss programs are a multi-billion industry, […]
A team of scietists from the University of Copenhagen have found a mushroom shaped animal which they believe doesn’t fit in any known subdivision of the animal kingdom. Such a situation has happened only a few times in the past 100 years. Researchers aren’t exactly sure where to fit it, but they have a pretty […]
A new study concluded that there’s about a 1 in 100,000 chance that the global warming in the past 60 years is not caused by human-released greenhouse gas emissions. It’s much more a debate between TV shows and regular Joes than it is between scientists – you could basically call it a consensus by now, […]
Researchers at University of Texas at Arlington conducted tests on more than 100 water wells in Texas and found 30% of these contained ‘alarming’ amounts of arsenic, enough to be considered carcinogenic and seriously threatening human health. These contaminated wells were found in the vicinity of known fracking sites and prior to drilling these were found […]
Researchers at the Hong Kong University of Science and Technology have created a thin metamaterial surface that is capable of absorbing nearly all of the acoustic energy (sound). Unlike conventional sound absorbing material that is sometimes only effective when meters thick, the metasurface is deeply “subwavelength” and therefore much thinner. There’s a catch though: the system has been demonstrated […]
The Advertising Standards Authority banned an ad which promoted fracking in the UK – this ad is really something else. It starts: “Dear Citizens of the United Kingdom, do you know that your country is blessed with an incredible gift?” OK, that’s fine, the UK has been blessed with lots of amazing gifts – but […]
It’s the first period in human history when the rich are thing, and the poor are fat – and this has a lot to do with something called the food gap. The food gap is basically what you’d expect from it (much like the wealth gap): there’s a huge difference between what rich people and […]
Stonehenge is one of Britain’s greatest national treasure, but while magic, myth and mystery surrounding the monumental site has been time and time again dispelled by science, there is still much to learn. One major debate regarding Stonehenge is whether or not the site once formed a complete circle. Now, a short hosepipe and a […]
A group of researchers has shown that neurons in the human skin perform advanced calculations. It was previously believed that only neurons in the brain can do that. The first order neurons conduct impulses from the skin (touch) and take the information to the spine and the brain; one of their most fundamental characteristics is […]
Globalization certainly has its ups: new markets, free trade, travel or economic growth (especially for developing nations). It's this latter aspect of globalization that might be the dominant factor that's wiping out languages from the face of the world, according to a study by researchers at University of Cambridge.
A recent study that assessed coffee and tea consumption habits of a whooping 131 000 people from France found that tea reduces non-cardiovascular mortality (non-CV) by 24%. Far from it, the same can’t be said about drinking coffee: consumers had a higher CV risk profile than non-drinkers, particularly for smoking. Overall there’s a tendancy to have a higher risk […]
Feynman was at times called "The Great Explainer" because of his skill at making complex subjects accessible to students, and while still a professor at Caltech he released his now famous Feynman Lectures on Physics. The three-volume collection has since become the most popular physics text book. Now, the whole collection is available for free, online for your personal consideration.
DARPA just announced the launch of a new extremely exciting program: Atoms to Product (A2P). The aim is to develop a suit of technologies that will allow manufacturing of products from the nanoscale up to what we know as ‘life size’. The revolutionary miniaturization and assembly methods would work at scales 100,000 times smaller than current state-of-the-art technology. […]
A team of scientists from the Massachusetts Institute of Technology (MIT) has been working on a research consisting of the manipulation of neural circuits in the brain of mice in order to alter their emotional associations with specific memories. The research, published in the journal Nature on August 28th, was led by Howard Hughes and […]
Scientists were surprised when they unexpectedly stumbled upon a relatively simple vaccine which blocks infection with SIV – the monkey equivalent of HIV – and stops the spread of the virus in already infected monkeys. How it works All efficient vaccines against a viral infection elicit virus-specific neutralizing antibodies and sometimes also cytotoxic T-lymphocytes (CTL) […]
NASA reports significant quantities of ozone-depleting chemicals are still leaching into the atmosphere despite an international ban signed by all the world's governments thirty years ago.
Researchers at Swansea University, UK and Uppsala University in Sweden built a mathematical model that explains how one single sheepdog can round up herds made of up to 100 sheep. Their conclusion suggests that the dog needs only to follow two simple mathematical rules.
Either when someone’s late for a date or you need to queue in line, our patience becomes tested. Some people handle the waiting better than others, leading us to the idea that patience is a virtue that differs from person to person. But what is it exactly that helps us remain patient, and why do […]
From the tropics to the poles, bird populations all over the world are facing a sharp decline, cornered by climate change and exposure to man-made biochemicals, namely pesticides. According to to BirdLife International, one in eight species (more than 1,300 species) of birds are under serious threat of becoming extinct. The list includes iconic birds of pray and song like eagles, vultures, swifts or swallows, but also seabirds like sandpipers, pelicans or storks.
Researchers from Stanford have found a way to split water into oxygen and hydrogen using very little energy; the hydrogen they obtain could be used to power fuel cells in zero-emissions vehicles. I’m quite excited for cars that run on hydrogen, which are set to hit the market in 2015; but while they are always presented as […]
Researchers have pinpointed the source of a huge environmental threat for AIDS patients – the source of a fungal infection which has been plaguing Southern California for years; it literally grows on trees. The finding was based on the research project of a 13 year old. Cryptococcus gattii, formerly known as Cryptococcus neoformans var gattii, […]
A while ago, we were telling you about the infamous “zombie ant fungus” – a parasitic fungus that reproduces by manipulating the behavior of ants. It’s one of the most gruesome acts in nature – the parasite fungi infect tropical ants, literally taking control of their actions, ultimately leading the infected ant to march to its death […]
A team of researchers from the Aarhus University in Denmark and CalTech has developed an origami-inspired method of organizing molecules on the nanoscale. The team has modeled RNA, DNA’s close cousin into complicated shapes using the technique. Together with DNA, RNA comprises the nucleic acids, which, along with proteins, constitute the three major macromolecules essential for […]
Bacteria living in obscure environments use an extremely rare process to harvest energy and produce oxygen from sunlight – but they don’t use visible light, they use far-red light. “We have shown that some cyanobacteria, also called blue-green algae, can grow in far-red wavelengths of light, a range not seen well by most humans,” said Donald […]
Seismic activity is continuing at the Bárðarbunga volcano and an eruption may still take place, scientists said on Sunday, but the emergency level has been downgraded from red to orange. “There are no indications that the activity is slowing down, and therefore an eruption can not be excluded,” the Icelandic Met Office said. Over 700 earthquakes […]
A whole functional organ has been successfully grown in animals for the first time; a group of Scottish researchers created a group of cells which, when transplanted into a mouse, developed into a fully functional thymus – a critical part of the immune system. The findings could lead to a revolution in organ transplant. The […]
A worrying report states that over 500 bubbling methane vents were found on the seafloor off the US east coast. The unexpected finding suggests that there are large volumes of the gas contained in a type of sludgy ice called methane hydrate and as global waters continue to heat up, the methane will be released in large […]
A new study of over 10,000 women has shown that women who breastfeed after giving birth have significantly lower chances of post-natal depression than their counterparts who didn’t. There are still many things we don’t yet understand about breastfeeding, as this study highlights – mothers who planned to breastfeed and were actually able to do […]
The physical properties of the ultra-white scales on certain species of beetle could inspire researchers to make better, whiter paper, plastics or paint, using far less material. The Cyphochilus beetle, native to South-East Asia, is whiter than paper or even milk teeth. The whiteness of its body is caused by a thin layer of a highly […]
Depending on where you live, bike stealing can be a distant threat or a constant worry, but in most parts of the world, people would rather be safe than sorry, tying their bikes to trees or fences or whatever they could find. But that may very well change in the near future: three engineers from […]
A medicine administered even up to 3 days after infection can save monkeys from the Marburg virus – an incredibly dangerous pathogen closely related to Ebola. “This clearly starts to move into the realm of being a therapy, rather than a post-exposure treatment,” says virologist Gene Olinger, principal science adviser for contract-research organization MRIGlobal in […]
If you thought research in airplanes only applies to the military, you’re wrong. While most of the money spent for airplane research does go to the military, a smaller chunk of it goes to space research, and another part goes to private air travel. Now, a company from the UK has almost developed an engine […]
It’s one of the most remarkable adaptations in the animal world – growing a tail or a limb. Some lizards do it, salamanders do it, and by learning how they do it, we may soon be able to do it as well; with technology, that is. A team of researchers have discovered the genetic “recipe” for […]
A new study shows that last an incredible 63 trillion gallons of groundwater were lost in the Western US alone – so much that it’s actually causing the ground level to rise. The Earth has lifted up about 0.16 inches over the last 18 months in the area, and up to 0.6 inches in the Californian […]
Observations of climate change often report a “missing heat” – a hiatus in the global warming, which went unaccounted for; but now, a new study concludes that the heat absent from the Earth’s surface for more than a decade is plunging deep in the north and south Atlantic Ocean, and this is part of a naturally […]
Between 5,000 and 8,000 gallons of diesel were spilled into the Ohio River on Monday, but officials say drinking water in the area is safe. Duke Energy is responsible for the spill, which happened during a “routine transfer”. While the company is still investigating, Duke spokeswoman Sally Thelen told the Inquirer that the spill may […]
Eating less meat could protect the driest areas of the world, saving much needed water. Reducing the use of animal products is very significant in all parts of the world, as meat production requires more water than other agricultural products, they say. In case you don’t know, every food we eat (and every product we use) has […]
