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 […]
An international team of scientists believe they have across the “microbial Pompeii” after they found preserved bacteria and microscopic particles of food on the surface of teeth more than 1,000 years old. The findings were made after the dental calculus or plaque that covered the ancient teeth was analyzed. Some very important discoveries were made in the process: ancient […]
During the Mesozoic, dinosaurs weren’t just roaming the land – giant reptiles, such as mosasaurs and ichthyosaurs, ruled the seas. But while scientists have a fairly good idea about how they looked like, until now, they had no idea what colors they featured. Paleontologists conducted new analysis at the SP Technical Research Institute of Sweden […]
Imagine salmon in reverse: long-snouted Bandringa sharks migrated downstream from freshwater swamps to a tropical coastline to spawn 310 million years ago – leaving behind a fossil nursery, which researchers found. The bandringa sharks The surprising conclusion was drawn by University of Michigan paleontologist Lauren Sallan and a University of Chicago colleague; they analyzed every […]
When you think about mongooses, cruel, despotic females probably don’t come to mind – but according to a new study, that’s exactly the case. To ensure groups remain ‘productive’, some social animals ‘police’ selfish reproduction by subordinate animals by killing any offspring they produce. In order to adapt to this behavior, some mammals may have […]
Cats, dogs, as well as many well known and loved wild animals such as seals, lions, tigers and bears trace their ancestry to primitive carnivorous mammals dating back to 55 million years ago, at the beginning of a time period called the Eocene. A study, published in the most recent issue of the Journal of […]
A while ago, we were telling you about the mysterious “fenced” white cocoons – of which researchers knew nothing about. The strange structures were photographed by graduate student Troy Alexander in the Peruvian Amazon. Now, we finally know what built them. Finding such a peculiar and unknown structure quickly went viral on the internet and […]
A cluster of 18 flowering plants from the Cretaceous (100 million years ago) has been found preserved in amber Among the flowers, one shows the earliest reproduction of flowering plants Based on microscopic imaging, paleontologists conclude that the pollination mechanism has remained virtually unchanged Amber is fossilized tree resin, valued as a gem since prehistoric […]
In nature, organisms communicate in various ways, be it through acoustic or biological signals. Insects, for instance, communicate and relay important information, such as a threat to a hive, using pheromones – an excreted chemical with a particular signature. Scientists at the University of Warwick in the UK and the York University in Canada have […]
With their eerie, translucent and soft bodies, their translucent and intricate shapes and bizarre bioluminescent displays, comb jellies are among the biggest beauties and mysteries in the oceans. Now, according to a biologist from Vanderbilt University, these delicate marine predators have another important story to tell about the origin of animals; a 550 million year […]
Researchers at MIT found that individual cells in a bacterial colony will grow in a manner that is beneficial to the whole culture, even if this comes at a personal expense for the cell. With this in mind, it appears seemingly complex colony structures can be explained by an essentially simple behaviour. The findings could […]
For most creatures, mortality increases sharply with age – and we typically consider this to be natural. However, other animals, such as the hermit crab, the red abalone and the hydra, a microscopic freshwater animal experience very different trends enjoying almost constant levels of fertility and mortality. For the desert tortoise, the mortality even decreases […]
We’ve written extensively about the impending global disaster triggered by the crippling of bee populations worldwide at the hand of Colony Collapse Disorder (CCD). Just recently, I wrote an article discussing the findings of a new paper that suggests the leading factors that cause CCD are most complex than previously thought – namely, a whole brew […]
Fractals are non-regular geometric shapes that have the same degree of non-regularity on all scales. Fractals are the kind of shapes we see in nature, basically, and even though the term was first coined only a coupled of decades ago or if this is the first time you’ve heard about fractals, chances have it that you […]
The pitch of male koalas’ mating calls is about 20 times lower than it should be, judging by their size and anatomical features. Now, researchers found that a unique sound producing organ, unlike anything found in other mammals, is responsible for this strange pitch. “We have discovered that koalas possess an extra pair of vocal […]
Two distinct groups of crocodilians have been reported to use tools for hunting They balance sticks on their snouts, baiting birds who want to use the sticks for nests Crocodiles actively search for the sticks (which are usually rare) and do this more often during the birds’ mating season It’s been known for quite a […]
Biotechnology is growing fast and the findings researchers are making the field are nothing short of breathtaking. Previously, ZME Science reported in the past few years alone a series of milestone premiers: the first bioengineered kidney and 3-D human kidney cells, the first functioning blood vessels, the first teeth-like structures, a bioengineered heart that beats on its […]
Ever found yourself in a hazardous relationship in which your spouse makes your hair go white? Well, if the answer’s yes then you’re not alone. A new study provides new evidence that key aspects of the social environment of some animals significantly influence life span after researchers found that sexually frustrated fruit flies and “haunted” […]
The Bonobo, or Pygmy Chimpanzee as it was once called, is one of our closest relatives, yet one of the most poorly studied. This fascinating ape displays unique social order and other highly interesting traits, and unfortunately like all great apes it is also endangered. Very little is known, however, about how many specimens are […]
Previously, it’s been shown that obesity can cause changes in the brain, leading some people to over eat food high in saturated fat and refined sugar, as well as cause poorer memory. A new study published by researchers at University at Buffalo found a new physiological trait that can become altered as a result of obesity. […]
Seahorses are some of the most awful swimmers, but they’re still very efficient hunters. 90% of their hunt attempts are successful, compared to the lion’s 25% and the shark’s 50%. Their snouts are shaped to minimize water disturbances, allowing them to creep up on their prey. Seahorses may appear cute and slow, but […]
When herbivorous dinosaurs went to sleep, they had bad dreams about Tyrannosaurs. But what where Tyrannosaurs afraid of? If you’re thinking “Nothing”, then you’re really wrong. A new species of carnivorous dinosaur (one of the three largest ever discovered in North America) competed with them 98 million years ago – the newly discovered species, Siats […]
To say that finding evidence of how life on Earth was 3.5 billion years ago is hard would be an understatement. Reconstructing the rise of life in its early stages is a monumental challenge – the evidence is only preserved in Earth’s oldest sedimentary rocks, and sedimentary rocks of that age are very hard to […]
Music isn’t only restricted to humans – music skills evolved at least 30 million years ago in the common ancestor of humans and monkeys, claims a new study that tries to explain why for example chimps drum on tree roots and monkey calls sound like singing. It’s one of the big puzzles in biology and […]
A strange evolutionary alliance between trees and the ants that guard them has a sinister explanation, a new study suggests, after studying ants hooked on nectar. Bodyguard ants and addiction In Central America, ants act as bodyguards for acacia trees, defending them not only from weeds, but also from animals, in exchange for accomodation and […]
The human body is a complex biological entity in seemingly perfect harmony as thousands of components play their part in tandem. Discovering, describing and understanding how each of this body parts function and work together is the primary role of human anatomy. Some of you might be surprised to find that human anatomy is yet […]
Researchers have found that methane-decomposing bacteria from hot springs need rare earths to produce the energy they need to survive. Rare Earth Elemenets (REE), or rare earth metals as they are sometimes called are a group of 17 chemical elements in the periodic table, specifically the so-called lanthanides plus scandium and yttrium. They are among […]
A giant platypus fossil, measuring more than 1m long (3ft) was discovered in Queensland, Australia. The animal lived 5-15 million years ago, as paleontologists explain in the journal Vertebrate Paleontology. Until now, the oldest fossil was dated 100.000 years ago. As if the evolutionary status of the platypus wasn’t extraordinarily complicated as it is, this […]
Any dog lover will tell you if you see a dog wagging its tail it’s a sign that the dog is happy. Apparently, there are subtle signals given off by variations in tail wagging and these are used to communicate with other dogs what their stance is. Researchers at University of Trento, Italy found that happy dogs […]
After performing an exhaustive quantitative research across numerous plant species, scientists at UCLA’s College of Letters and Science have found that leaf design is governed by a set of fundamental mathematical expressions, underling once again the elegance of nature. The basis of their research was “allometric analysis”, that is to say the study of an object’s evolution […]
One of the greatest mysteries scientists have been trying to reveal is how inanimate chemicals joined to produce life. It’s definitely one of the biggest questions scientists are trying to answer, and the challenges are numerous since it’s very difficult to appreciate what the exact conditions necessary for this to happen were billions of years […]
Craig Venter may just be the most arrogant high-profile scientist today, but in his defense the man has a lot to show for. You might not remember the name, but you might remember his hallmark achievement – the creation of the world’s first synthetic life. Now, with the release of his second book, Life at the […]
Some of you might find it surprising to hear that a lot of animals engage in homosexual behavior. Close to 1,500 species, ranging from primates to gut worms, have been observed engaging in such behavior and this is well documented for 500 of them. No one comes close to insects and spiders, though, which have […]
