Plants can communicate with each other, signaling a potential incoming attack through an underground network of fungi, researchers found. Instances of plants communicating with each other have already been picked up through the air – with chemicals emitted by one plant being picked up by another plant. But below ground? They rely on fungi called mycorrhizae. A […]
Rising temperatures could provide a short term boost in the numbers of turtle populations (as hotter water stimulates the growth of female offspring), but if the current trends continue for a long time, the entire population might go extinct soon. ”There’ll be a bit of a breathing space … but down the track it’ll be […]
Most cancer diagnosis tools and procedures today involve detecting the disease on the microscopic level. There is no single test that can accurately diagnose cancer. The complete evaluation of a patient usually requires a thorough history and physical examination along with diagnostic testing – a lot and a lot of tests. If that wasn’t enough, […]
Roboticists and mechanical engineers hold octopuses to great respect and admiration because of their many skills, like great water propulsion, camouflage and independent limbs. Each octopus tentacle is equipped with numerous suckers that allows it to easily cling to most surfaces, no matter how smooth they may be. Whether the octopus needs to attach itself […]
Inspired by the healing properties of the human liver, researchers at University of California, San Diego created a 3D-printed biodevice which mimics the liver and removes dangerous toxins from the blood. Used outside the body, like a dialysis machine, the device employs nanoparticles to trap pore-forming toxins that can damage cellular membranes. These toxins often result from […]
For the casual nature enthusiasts, snails are a infinite source of joy whenever people come across them. People like to study them and revere how beautiful they are in their own microcosmos – for a while at least, until they get bored that is; it’s a slow paced microcosmos after all. For others, snails are […]
In a feat that surprised even the scientists who made the experiment, mice disabled by a condition similar to multiple sclerosis (MS) began to walk and even run again after human stem cells had been transplanted. The findings could potentially offer new means of treating MS, a terribly disease which plagues some 2.3 million people worldwide. Growing […]
The humongous grey whale and the skipjack tuna, though of contradicting sizes, both employ similar propelling mechanisms through water. Pound per pound, however, which of the two animals is most energy efficient? Engineers at Northwestern University have developed a new metric for analyzing such problems and found that the two marine animals are almost just as […]
This is one of those science stories where it gives to show that even scientists can be biased and, most of all, that it’s only when you stand-up and become willing to contradict yourself that you come closer to the truth. Peter Gibson, a professor of gastroenterology at Monash University and director of the GI […]
In the animal kingdom, especially among those that are social, you’ll see a number of strategies employed to help the group’s chances of surviving. To each his own. For instance most ant colonies employ a social hierarchy where most members, like the worker ants, are rendered functionally sterile and only the absolute top of the […]
Scientists from the Philippines have discovered a new plant with an unusual lifestyle – it eats nickel for a living. The new species is called Rinorea niccolifera, and it’s a part of the same genus as violets and pansies – but it has few things in common with those plants. Rinorea niccolifera‘s preferred food is nickel, accumulating up to […]
The entire living world is “written” with just four DNA bases: A = adenine C = cytosine G = guanine T = thymine However, for the first time, researchers have now created a living cell with an added pair of DNA “letters,” or bases, not found in nature – the DNA alphabet just got some new letters! “Life on Earth […]
It’s so cold even penguins get the flu in the Antarctic. Seriously, researchers report in a paper published in the journal mBio how they identified a new strain of influenza that infects Adelie penguins which breed in huge colonies on the rocky Antarctic Peninsula. The virus itself seems to be dormant as the penguins don’t exhibit any visible flu […]
Dogs and puppies are really good at interpreting human vocal and visual cues, with previous studies already showing they can pick up even subtle hints, finding hidden food with just a slight look from a human. Researchers of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, have now studied for the first time whether dogs […]
Negative emotions like fear, sadness and anger evolved serving a purpose – enabling people to adapt to the changing conditions in the environment, reacting flexibly and efficiently to stress and strain. However, in modern society, in certain situations, we’d really like to avoid experiencing those feelings, as well as many others, like depression or anxiety. Researchers […]
This Sunday a trio of landmark studies were published each discussing an aspect of a wider picture: reversing aging in the muscles and brains of old mice simply by transfusing blood coming from younger mice. The effect is credited to a key protein found in much higher concentration in the blood of younger mice. So far, the findings […]
Cheetahs are the world’s fastest land animals in the world, able to run as fast as 75 mph. It’s their acute agility that allows them to survive, however, catching prey by making huge leaps at four times the acceleration human leg muscles are capable of producing. No doubt about it, this is one of the […]
One of the most threatening modern pandemics, HIV/AIDS, has been thoroughly studied in the past few decades, with billions awarded to research seeking out a cure. Progress has been slow, but today doctors have a number of tools at their disposal to curve HIV development, spreading and ail patients, despite a cure has yet to […]
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 […]
