Scientists have unanimously agreed […]
A team of researchers at MIT have successfully manage to fabric a fuel cell capable of running on glucose, which scientists envision will power highly efficient medical implants in the brain that can help paralyzed patients express motor functions again. The outputted power is in the microwatt range, but despite its low range, scientists claim it’s just enough to […]
Carnivorous plants may soon have to give up their meaty habits and turn veggie, as a recent study found that carnivours plants in Swedish bogs have significantly reduced their preying behavior, due to nitrogen pollution. The sundew drosera rotundifolia is one of the most common carnivours plant species, growing across much of Northern Europe in rain-fed bogs. […]
Be it a bacteria or a fully complex being, say a human, all living, biological organisms undergo lighting fast protein structure reassembly in response to environmnetal stimuli. For instance, receptor proteins in the sinus are stimulated by various odor molecules, basically telling the organism that there’s food nearby or it’s in the vicinity of danger (sulphur, methane, […]
Using the Subaru and Keck optical/infrared telescopes on Hawaii’s Mauna Kea, a 4,200 metre-high summit which houses the world’s largest observatory for optical, infrared and submillimeter astronomy, a team of Japanese astronomers claim in a recently published paper that they’ve discovered the earliest galaxy found thus far in the known Universe – it is 12.91 billion years […]
This time last year, the whole scientific community was faced with one of the most controversial findings in recent history – namely, that neutrinos could travel at a speed greater than the speed of light, fact which would directly contravene with Einstein’s Theory of Special Relativity and, in consequence, force scientists to rethink the fundamental laws that […]
First discovered in 2005, and then studied in more depth since 2007, NASA scientists have finally isolated the ethereal glow thought to originate from the very first objects in the Universe with the highest precision yet. As seen in the image above, depicted in orange and red, the ‘lumpy’ infrared glow was observed using the […]
This month, the 20th anniversary of the 1992 Earth Summit in Rio, an United Nations conference where various issues where addressed like the systematic scrutiny of patterns of production, alternative sources of energy to replace the use of fossil fuels, new reliance on public transportation systems in order to reduce vehicle emissions or the growing […]
Fed by ignorance, hypocrisy and frustration, members of an international group of eco-anarchist have, during the past few years, plotted and attacked various scientific facilities and scientists alike, injuring many in their attempts and seeding fear, in an anti-technology and science ploy. The violent attacks were self-attributed by the various organisations working in close tandem, […]
A team of international scientists from Britain and the United States have devised a new mathematical formula, considered more accurate than previous methods, which measures the body weight of dinosaurs – they found that dinosaurs weighed much less than previous estimates had considered. For instance, the giant Berlin Brachiosaur, which lived in the late Jurassic period (from about 200 […]
Atom = at·om, noun \ˈa-təm\, from the greek ἄτομος (atomos) meaning “indivisible”. Apparently the atom isn’t that indivisible after all. Scientists at the University of Bonn have managed to split an atom into two with a special laser, in special conditions, before merging it back together. Just like in the case of light, quantum mechanics allowed an atom to be split […]
A new study from anthropologists at University of Tennessee analyzed the skulls of caucasian American men and women from between the mid-1800s to the mid-1900s. Their findings showed that the average American’s skull today is larger and narrower than it used to be seven generations ago. In total, over 1,500 skulls have been analyzed, and though […]
Now this is something that doesn’t happen everyday, especially from behalf of one of the most paranoid and money-gobbling organizations in the world, an US intelligence agency. According to a recent press release from NRO, the secretive government agency that flies spy satellites, two such functional and high-capable spy satellites were handed over to NASA as […]
Many efforts and funding have been put into countering vibrations, such as the ones produced by an internal combustion engine, to dampen shocks and reduce noise. Much progress has been made; you only need to compare two vehicles, one twenty years old, the other brand new, and you’ll instantly notice the differences. One, noisy and […]

Genetic diversity is what keeps species evolving, helps them tackle diseases and is a prime pre-requisite for natural selection. Understanding genetic diversity is imperitive for scientists in the field, whether it’s about identifying associations between genetic variants and diseases or highlighting interesting aspects of human population history. One of these aspects is geographical location. Remarkably, an international […]
Besides ever thinning ice, permafrost melting, soot deposits, habitat loss, you might as well add another significant factor threatening the arctic ecosystem – mercury. For some time, the alarmingly high mercury concentrations in the regions were rather unaccounted for, in part, however a new research by scientists at Harvard’s Atmospheric Chemistry Modeling Group suggests that […]
A group of researchers at University of British Columbia and the Smithsonian Institution have discovered a new sensory organ in rorqual whales, a subspecies of baleen whales, which also includes the largest animal that has ever lived, the blue whale, capable of reaching 150 tonnes. The scientists involved in the study claim that this organ plays a vital role in […]
Last Saturday, after many meticulous preparatory stages and a couple of exasperating postponements, SpaceX was set to launch its Falcon 9 rocket, along with its Dragon capsule filled with food, supplies and science experiments destined for the International Space Station. A faulty valve, however, signaled officials to abort the launch with just ONE second to go. Years and […]
In an absolutely remarkable discovery, Professor Yun Hang Hu, along with associates at Michigan Technological University, have discovered a chemical reaction which can turn the alarmingly ever increasing greenhouse gas carbon dioxide into a solid-state semiconductor (Li2CN2), while also releasing energy in the process. You couldn’t ask for something better. CO2 is an extremely pesky compound for […]
A new study published by the Department of Energy’s Pacific Northwest National Laboratory found that pollution leads thunderstorm clouds to capture more heat than in normal, clean air conditions, thus becoming a contributing factor to global warming. Thunderclouds or deep convective clouds, by the scientific term, generally form and develop in any geographic location and […]
Nothing short of extraordinary, two people paralyzed from the neck down controlled a robotic arm to perform actions of various complexity, like manipulating objects, simply by using their minds. One of the participants involved in the demonstration of the brain to robotic arm set-up actually controlled the arm to retrieve a coffee recipient and eventually drank from […]
Scientists have uncovered pieces of fossilized amber containing tiny female insects called thrips, which upon closer inspections were found to have particles of pollen dusted over them. The insects found are around 100 million years old, officially making them the oldest pollination record ever found. During the lower Cretaceous Period, which corresponds to the recently discovered […]
According to the World Wildlife Fund‘s annual Living Planet report, humans are using Earth’s resources at a rate 1.5 times greater than the rate of replenishment. “During the 1970s, humanity as a whole passed the point at which the annual Ecological Footprint matched the Earth’s annual biocapacity. This situation is called “ecological overshoot”, and has continued since […]
The Cross River gorilla is a critically endangered gorilla species, native to the border region of Nigeria-Cameroon. Today, only about 250 to 300 individuals are alive, due to habitat loss and poaching, making it the rarest of all four gorilla species. It’s so rare and elusive, that no one has ever been able to record […]
Since the space shuttle program was cancelled last year, NASA has been looking for various alternatives to sending manned crews in space, particularly the International Space Station. A number of private space companies have jumped on the bandwagon since then, spearheaded by SpaceX, which is slated to make its first flight to the International Space […]
Astronomers have observed a huge sunspot group on the surface of the sun, sized at more than 60,000 miles across, which might outbreak in a potentially hazardous solar storm. From time to time, the sun spews huge energy releases called solar flares, which depending on their magnitude (the weakest are “C” class and the most powerful are […]
Horses are arguably one of the most helpful animals man has ever managed to domesticate. At first they were used as source of meat and milk, but it was soon evident that horses were a lot more suited as labor animals than as a direct food medium. Important agricultural advancements were made possible thanks to horses, and […]
Last year, we reported on one of the most gruesome and horrific acts that goes on in nature; it seems so unreal, like if some sort of SciFi monstrous scenario transcended into the realm of reality, that one has a hard time wrapping his head around it. Yes, as some of you might have read previously, I’m […]
Skin and hair color are most inherited from parents, and usually hint pretty accurately to a person’s ethnicity. Dark skin and hair are most common in the regions around the Equator, however natives of the Solomon Islands, an archipelago east of Papua New Guinea, seem to defy common expectations, as around 10% of the population […]
An interesting conversation can instantly make a turn for the worst when bad breath hops into the scene. We’ve all had our share of bad experiences whether we were more or less forced to tolerate the repulsive stench of bad breath or we had a case of bad breath ourselves. Scientists at Nippon Dental University, […]
During the tumultuous Cretaceous and Jurassic periods if you could only choose one word to describe the world, it would’ve certainly be ‘big’. Big dinosaurs, big plants, big trees, big fish and big insects, of course. Chinese scientists have found almost perfectly preserved fossils of two previously unknown extinct flea species in Inner Mongolia, which are roughly […]
Most digital devices today, like displays or blue-ray disks, use lasers which emit the colors red, green and blue, which when combined can render any color in the visible spectrum of light. However, current technology requires a separate laser for each color, since they produce monochromatic light. A team of researchers at Brown University has […]
Evolution, in very loose lines, is defined as the process which allows a species to survive by passing on the differentiating traits most likely to help offspring adapt to the world through means of natural and sexual selection. Considering the world around us has been shaped so much by human hand, a lot of people […]
Summer is set to kick-off with a series of beautiful Venus related events, from an astronomical point of view at least. This week, the planet will appear at its brightest in the night sky, as it nears almost ideal observational circumstances – close distance to Earth and sun phase. Also, at the beginning of June, […]
A team of researchers at Penn State University has identified 24 new species of skinks, a subspecies of lizards, native to the Caribbean Islands, turning the region’s fauna from one of the smallest lizard groups in the world to one of the largest. However, half of these new species are considered already extinct or very […]
Astronomers classify galaxies into three basic types: elliptical (flat, elongated shape), spiral (most easily recognizable and common – described by their disk shape and outward spiraling arms) and irregular (usually described by a irregular shape, typical to very young galaxies). One of the most fascinating galaxies known to man is the Sombrero galaxy, shaped like a hat […]
The Amur leopard is a beautiful leopard subspecies native to the region of the Russian far east, which since 1996 has been classified as critically endangered.

“Would you make the same decisions in a foreign language as you would in your native tongue?” asks Boaz Keysar, a psychologist at the University of Chicago, who recently published a study that discusses this highly interesting question. The scientists involved in the study found that, indeed, counter to popular belief thinking in a foreign […]
A team of international scientists claim that they’ve found evidence of the first non-human species that cultivates planets for non-food purposes. The extremely fine feathered bowerbirds, native to Australia and Papua New Guinea, display an unique courtship behaviour, where males build a home-like structure, called bower, and decorate it with sticks, little stones, and brightly coloured […]
Scientists have described and proven how many of the world’s phenomenae function, from the very fundamental laws of Newtonian mechanics, to the discrete behaviors of quantum physics, eventually peering through some of the Universe’s most well kept secrets. It’s remarkable then, how little we know about how heat is conducted through and between materials. A better […]
The age-old question of who came first – the chicken or the egg – has been pondered countless times, and put great thinkers throughout history in a predicament. An oddity of nature which recently occurred on a Sri Lankan farm may offer clues towards answering the riddle. There a hen gave birth to a chick without […]
One of the cutting edge technologies currently used today in manufacturing allows for printing materials directly onto a surface to create electrically functioning devices which are very thin and flexible.
