The animal kingdom is full of cons – shapeshifter who have learned that to survive, they need look different or mask their appearance altogether. Everyone’s heard of the chameleon, a distinct species of lizard with the ability to change colours and easily blend to his environment. He’s not alone, though, and frankly he’s not even […]
No matter how much some would like to avoid this prospect, death is inevitable for all living beings (or is it?). Yet, some people at least live longer than others. A great deal of attention has been drawn to longevity for obvious reasons, but any effort to prolong life needs to start with the very […]
As the night covers the tropics, odd clicky sounds run about much to the annoyance of sailors stationed in harbors. These sounds are made by the punching mantis shrimp, a very small crustacean which doesn’t seem that much threatening but who definitely lives up to its name. Its claws are so powerful that it can […]
After analyzing samples from eight different carbon-rich meteorites, researchers at Pennsylvania State Universities found these contained niacin, also known as vitamin B3 and the more pristine the meteorite, the higher the concentration. What this means is that the ancient Earth had a steady supply of vitamin B3 during its early years when it was frequently […]
A cochlear implant that can be wirelessly recharged using the natural microphone of the middle ear rather than a skull-mounted sensor was developed by a joint team from MIT and Harvard. The cochlea is the auditory part of the inner ear – t’s where the hearing takes place. Cochlear implants are not really a new thing […]
A female insect has developed a spiky penis which it uses to get in charge . It’s a role reversal, basically: not only do the females have a penis, but the males have a vagina. The males still have sperm, but the female extracts it from the male vagina using its penis. Sounds strange, doesn’t it? […]
You could be sitting alone and still be completely outnumbered for your body is home to trillions upon trillions of tiny passengers – bacteria. In fact, there as ten times more bacteria living inside you then cells in the body. Don’t get scared, though. The vast majority of these co-redident organisms are our friends. They […]
Humans are great social beings because we have an extraordinary ability to distinguish between our fellow bretheren. If you don’t suffer from prosopagnosia, also known as “face blidness”, chances are you’ll be able to easily recognize a friend’s face or voice out of a myrriad of other humans. This kind of mental ability is extraordinary […]
We’re currently experiencing the worst spate of species die-offs since the loss of the dinosaurs 65 million years ago. Although extinction is a natural phenomenon, it occurs at a natural “background” rate of about one to five species per year. Scientists estimate we’re now losing species at 1,000 to 10,000 times the background rate, with […]
Last week, the story of a German fisherman made front news after he found a message in bottle floating in the Baltic Sea for nearly 101 years. What’s more, despite most of the text written was undecipherable, researchers at the Hamburg Museum were able to find the sender’s name and deliver the message to his […]
Researchers at the National Research Foundation of Korea report on Sunday that they have identified a new microRNA molecule that suppresses a gene, which previous research had identified as playing a crucial role in lung cancer development. If the present findings are refined, it may be possible to diagnose lung cancer in the future based […]
For the nearly six million Americans living with paralysis, 1.3 million of which with spinal cord injuries, life is often a struggle. Few are independent, and this causes severe psychological strain. Physiotherapy has proved it can do wonder in some cases, but what if you could push it a bit further? Building up on previous […]
Many parasites affect their hosts’ behavior, up to the point where the host can sacrifice itself for the wellbeing of the parasite; it’s an extremely cruel fate for the host, but a really good evolutionary adaptation for the parasite. Good examples are horsehair worms that reach water by forcing their cricket hosts to drown themselves, […]
At the turn of the new year, we marveled how Swedish doctors transplanted no less than nine wombs in patients who suffered from Mayer-Rokitansky-Kuster-Hauser syndrome or MRKH. Now a team of researchers from Mexico and the US have gone a whole step further – they engineered vaginal tissue in the lab and transplanted it in […]
Without oxygen, your brain would shutdown within five minutes or so and you, as a person, along with it. Deprived of this fundamental element, brain cells can’t produce energy anymore and wither and die. Breathing is important, that’s pretty settled but what happens if you can’t rely on your lungs anymore. A team of researchers led […]
The popular myth of the fountain of youth tells the story of a magical spring that restores youth to anyone who drinks from it. Scientists working with longevity research have made important strides forward in recent years, however all of these efforts concentrate on prolonging life and slowing the effects old age has on the […]
Researchers in South Korea may have come across a novel and effective idea to tackle foods tainted with Salmonella bacteria. What looks like a disk actually contains six separate microfluidic slices that work together to provide DNA extraction, amplification, and detection in less than 30 minutes instead of days and a full-blown lab typically required for Salmonella detection. Salmonella causes […]
Trying to understand the overall effect of climate change on our food supply can be difficult. Increases in temperature and carbon dioxide (CO2) can be beneficial for some crops in some places, but overall changing climate patterns lead to frequent droughts and floods that put a severe strain on yields. It’s not all about production, […]
In the future, your saliva might power key microelectronics. Researchers at Penn State have devised a micro-sized microbial fuel cells that is power by the organic materials and bacteria present in saliva. The power generated by the tiny fuel cell is very small, though, so don’t expect charging your phone by spitting in it any […]
The characteristic “chirp” a cricket makes is created when the insects rub their legs, in an attempt to draw the attention of any nearby female. If he is successful and finds an interested counterpart, the couple quickly gets down to business. Interestingly enough, it’s the female that mounts the male, but that’s less important here; […]
Heralded as one of the biggest advances in the field, scientists at Duke University have engineered muscle tissue that is up to ten times stronger than anything previously achieved. The muscle can contract similarly to native neonatal skeleton muscle and, most importantly, it demonstrates self-healing ability – again, just like the real thing. To demonstrate […]
Most people nowadays buy antibacterial soaps instead of normal ones, because they believe it keeps them safe and protects them for the oh-so dreaded bacterial infections. Apparently, there’s little evidence that antibacterial soaps provide any additional protection than the regular kind. The problem: most people don’t use them properly. For that matter, it may be […]
New Caledonian crows understand ow to displace water to receive a reward, with the causal understanding level of a 5-7 year-old child, according to results published March 26, 2014, in the open access journal PLOS ONE. Just a few days ago, we were presenting a study which showed that goats are smarter than previously believed, […]
For the half-dead arriving at hospitals, like the unfortunate who suffer gunshot wounds or lose a lot of blood some other way, there’s very little doctors can do. There are so little life saving procedures and surgeries that can be performed, and doctors need their patients at least a few more hours to be alive […]
Testing drugs on 3-D printed human tissue might significantly improve drug research.
Cambrian fossil is earliest example of large swimming filter-feeder. An evolutionary explosion Half a billion years ago, the world was extremely different. We’re in the Cambrian, the first geological period of the Paleozoic Era, which lasted from about 541 to 485 million years ago. Life is diversifying at an incredibly fast rate, into what we […]
In a huge breakthrough in synthetic biology, scientists at Johns Hopkins University have engineered from scratch a yeast chromosome. This is the first time scientists have been able to assemble a chromosome from a creature as complicated as a yeast, namely a prokaryrite. The implications of this research are far and wide. For one, the […]
Crops, like any plants, adapt to their surroundings and, depending on conditions, can offer more or less yield. In the biggest study of its kind, the results from 1,700 published simulations that evaluate yield impacts of climate change were compiled and analyzed together. The team of researchers involved in this massive aggregation found that even a 2 degrees […]
Scientists have used one of the brightest light sources in the Universe that we know of to expose the biochemical structure of a 50 million-year-old fossil plant to stunning visual effect. The mixed team of paleontologists, geochemists and physicists bombarded the fossils with extremely bright X-rays and showed that the chemical makeup of the plant […]
New research from Queen Mary University of London shows goats quickly learn how to solve complicated puzzles and can remember the solution for at least 10 months, which might explain their remarkable ability to adapt to harsh environments. Basically, scientists trained a group of goats to retrieve food from a box using a sequence of […]
According to a study published Monday, the Western Corn Rootworm (actually a beetle larvae) has already developed a resistance to not one but two strains of generically modified corn; this happened mostly thanks to the over-reliance and improper implementation of the crops by farmers. Genetically modified organisms (GMOs), for all the bad rep they get, […]
Some thirty years after Chernobyl’s nuclear plant meltdown that caused an international incident, scientists have yet to assess the full blown damage the radioactive disaster has caused. While the rest of the world has moved on, ever since the disaster the area surrounding the former nuclear plant has remained largely unchanged, even the plants and […]
There’s a common number thrown around for how many scents a human can smell – 10,000. Even scientific literature has cited this figure, though it is highly debatable. This makes a lot of people believe that they have an extremely poor sense of smell compared to most animals, like familiar canines. In reality, it seems […]
High voltage power lines aren’t quite the safest places to be around, especially if you’re a large animal or bird and touch two different conductors, thus creating a voltage difference which kills on the spot. Apparently, though, not too many animals wonder near power lines. Roads are known animal traffic disruptors, but even power lines […]
Researchers have shown that after being frozen over 1,500 years in Antarctic ice, moss can come back to life and continue to grow. For the first time, this vital part of the polar ecosystem has demonstrated its ability to survive after being frozen for over such an incredibly long time. Well, to be perfectly fair, […]
Human stem cells can remember what surface researchers have grown them on. This mechanical memory in fact influences the fate of these stem cells, such as whether they start differentiating into bone or fat cells. Basically, they remember if they were on a hard or soft surface, and this influences their future. This remarkable fact […]
One of the 16 teams involved in a collaborative project funded by the Bill & Melinda Gates Foundation that aims to help some of the 2.5 billion people around the world lacking safe and sustainable sanitation recently unveiled their innovative design: a solar-powered toilet that treats solid waste by effectively carbonizing it. The concentrated solar […]
An international team of geologists captured a prehistoric portrait of parental care deep in the fossil record. The team led by Leicester geologist Professor David Siveter revealed a ‘sea nursery’ which features a species new to science. This new species was found with specimens preserved incubating their eggs together with probable hatched individuals. As a […]
Scientists believe they will be able to extract high quality DNA from remains which have undergone a unique autopsy in Yakutsk, capital of the Sakha Repblic, also called Yakutia, in Siberia – they also believe they will be able to clone a wooly mammoth based on those remains. There was a wave of excitement spreading […]
When you buy your spices, you might be getting more seasoning than you might expect. Why not get some free tiny fragments of insects, dirt or animal feces to go with your chilly? According to the Food and Drug Administration spices entering the U.S. are nearly twice as likely as the average FDA-regulated foodstuff to contain Salmonella pathogens […]
The human body is littered with free ions and salts, which goes to explain why so much of our physiology is controlled by electrical signals, from neural pathways to muscle articulation. Very related, researchers at UC Berkeley have shown for the first time that direct current can be used to deliberately guide migration of a sheet […]
The wild is often home to a game of hide or seek, and animals need to be well adapted to their part of the game. For those who are constantly juggling the role of prey, however, the game seems to always favor them less. We, as humans, have little direct contact with these underlying mechanics […]
Some 20.000 years ago, mammoths and other giant fauna roamed the Earth. So too did this giant virus – the only difference is that this virus, Pithovirus sibericum, is still around and doing fine. Large enough to be seen under a light microscope, Pithovirus sibericum is not the first megavirus to be found, but at […]
It may be the birth of a new supermaterial – not long ago, spider silk materials were considered science fiction. Despite being a bio-material and basically a protein, spider silk has some amazing properties: it is by weight five times stronger than steel and three times tougher than Kevlar. Just so we’re clear, strength is […]
After growing up to adulthood blinded from birth, a man now has taken a peculiar hobby: photography. Were it not for the efforts of a group of researchers who have devised a system that converts images into sequences of sound, this new found pastime had been impossible. Hobbies or not, the technology is particular impressive […]
A wonder pill that prolongs life and cuts the risks of developing deadly diseases. Scientists have been looking for such a drug for a long time. Research in this direction shows that enhancing the expression of a certain gene called SIRT1 (sirtuin 1) may fare good results in this respect. Recently, researchers at the National Institute […]
During the harvest last year, many farmers from Jordan and Mozambique reported that their plants looked nothing like what they’ve been harvesting for decades, instead turning into something like this: Scientists first discovered that this fungus was wreaking havoc in Southeast Asia in the early 1990s. Since then, the pathogen, known as the Tropical Race 4 […]
You may not find many interesting things to see when glaring into a chicken’s eye, but after closely studying its retina researchers at Washington University have come across a most fascinating discovery. It seems chicken eyes bear a never before seen state of matter in biology, an arrangement of particles that is both ordered and […]
For the first time, researchers have taken a look at the life that thrives in one of the deepest spots in the ocean. They investigated the New Hebrides trench, located just West of Vanuatu, and revealed that cusk eels and crustaceans teem more than 7,000m (23,000ft) down. They used cameras fitted on an unmanned lander […]
Even the most untrained, layperson neuroscientist has the correct sense to recognize memories are realized by the brain, that the brain resides in the head, and so it follows removing the head displaces the memories ostensibly to wherever the head now resides. Now introducing the planarian (c. Elegans), a standard organismic model in behavioral and […]
