Despite efforts, Creationism Creeps into U.S. Classrooms

    If we were to state the obvious, there are 2 sides: creationists and evolutionists. Creationists are mostly religious people, and they believe humanity, life, the Earth, and the universe were created in their original form by a deity. Of course, evolutionists accept the scientific theory of biological evolution by natural selection or genetic […]

Sleep deprivation makes it hard to make sense of what we see

    It’s still unclear how sleep deprivation affects us, as there are still so many things scientists have failed to understand about sleep itself. But now, neuroscientists at the Duke-NUS Graduate Medical School in Singapore have shown for the first time what happens to the visual perceptions of healthy but sleep-deprived people who struggle […]

Technique Images Brain Activity When We Think Of Others

Just like when you lie certain things happen in your brain, the same thing happens when you think something about somebody. But what happens in our brain when we judge people or at least when we make an idea about someone? Those (and many other) questions have been tackled by MIT neuroscientist Rebecca Saxe. Her […]

Science ABC: why are emotional memories of traumatic events so strong?

  Photo by ±‡ U a € ï ¥ a H ‡± Life has ups and downs, reminding more or less of an emotional rollercoaster; but some memories stay in your memory way longer than the others. Emotional memories of traumatic life events (physical or mental), especially cases of accidents or serious illnesses are stored […]

6 record holding animals you'll never be as good as

Photo by bocavermelha Sometimes, animals are better than humans. Quite a lot of times actually, but that’s not the point here. We’re going to take a look at some record holding animals that are (or do things that are) just unbelievable! The biggest – the blue whale. Photo by Dan Shapiro. Credit: NOAA via pingnews […]

Special K for depression

    Well this sure sounds like a good plan to me… Scientists found out that Ketamine (also called Special K if you hang out with the right people), which is used as a horse tranquilizer but also as a club drug could ease depression. Who would have guessed ? Ketamine, which can also cause […]

Meet the "oldest" Praying Mantis

    Well this is a bit of a stretch; the thing is an 87-million-year-old praying mantis was found encased in amber in Japan. Scientists believe it may prove to be very useful in establishing a connection between mantises from the Cretaceous period and modern-day insects.Researchers have been searching for this “missing link” for many […]

Life Expectancy Worsening Or Stagnating For Large Segment Of U.S. Population

How can this be? Medicine has progressed… we have drugs for everything, surgery, etc. So how come people live less and less in a country that claims to be the most civilized in the world ? In fact, it decreased with more than six years for women between 1960 and 2000. Now, a new, long-term […]

Bloodless Worm Sheds Light on Human Blood

University of Maryland researchers have managed to shed some light in an important matter which puzzled medical scientists and not only for ages: how iron carried in human blood is absorbed and transported into the body. Among the benefits of this discovery I’ll just name a better understanding of iron deficiency, the world’s number one […]

Bikini corals are recovering from atomic blast

Bikini Atoll (also known as Pikinni Atoll) is an uninhabited 2.3-square-mile (6.0 km²) atoll in one of the Micronesian Islands in the Pacific Ocean. Its historical importance lies in the fact that along with more than 20 nuclear weapons tests between 1946 and 1958, the world’s first test of a practical dry fuel hydrogen bomb […]

Decision-making could be unconscious

What makes us different is not who we are, not what we think, but the decisions we make. That defines us, it’s what makes us different from others. But aside what you’d want to think, it turns out decision-making may be a process handled to a large extent by unconscious mental activity. A team of […]

Lungless frog found

The first lungless frog has been discovered lurking in the jungles of Borneo. This amphibian is totally enigmatic, at least until now, for scientists who haven’t been able to figure out how come it gets all its oxygen through its skin. Scientists first discovered these frogs about 30 years ago but because they’re so rare, […]

Global warming posts new threats - Australian wildlife

The threat that global warming is has definetly been underestimated, and if something doesn’t develop quite fast that could handle this problem or at least diminuate its effects (could it be iron fertilization?), the perspectives are quite dire. Everything and everybody is affected, and the effects include the melting of glaciers and the destruction of […]

Crawling, not swimming fish discovered

A University of Washington fish expert claims to have discovered a whole new species of fish, that would rather crawl into crevices than swim, and that may be able to see in the same way that humans do. Well this is certainly something unexpected, and there is no species that does the same kind of […]

Evolution slows down as number of competitors increases

According to a new research, published in PLoS, as the total number of different species in a certain group grows, the chance of the rate of new species apprearing decreases greatly. The research team believes these findings suggest that new species appear less and less as the number of species in a region approaches the […]

Prions picked up by tuning fork detector

    Prions (or proteinaceous infectious particle; on comes from analogy to virion) are the nasty little buggers responsible for disorders such as mad cow disease and other neurodegenerative diseases. They’re dangerous especially as they’re really hard to detect before symptoms appear. Now, according to Nature, scientists are trying to develop sensors that can detect […]

Evolution - 2 billion years late ?!

Recently, the University of California, Riverside provided some materials that shocked me, to say the least. According to that research, scientists from all around the world have reconstructed changes in Earth’s ancient ocean chemistry during a broad sweep of geological time, from about 2.5 to 0.5 billion years ago. What they found was that the lack of […]

Language Feature Unique To Human Brain Identified

There’s always been a lot of effort put into understanding what (if something) makes humans superior to other man-like mammals. The science world seems to be split into two camps, which can’t agree with each other. Now, researchers at the Yerkes National Primate Research Center, Emory University, have identified a language feature unique to the […]

'Living dinosaur' is fastest evolving animal

Professor David Lambert and his team from the Allan Wilson Centre for Molecular Ecology and Evolution performeda study of New Zealand’s “living dinosaur” the tuatara. They recovered DNA sequences from the bones of ancient tuatara which are up to 8000 years old. The conclusions they drew were amazing: despite all the ods, the tuatara has […]

Major advance in computational chemistry: Designer Enzymes

In what is a great leap for science, scientists from UCLA and the University of Washington have succeeded in creating “designer enzymes,” a major milestone in computational chemistry and protein engineering. The two groups were led by UCLA’s chemistry professor Kendall Houk and Washington’s biochemist David Baker. Designer enzymes will have applications for defense against […]

First ‘rule’ of evolution suggests life will become more and more complex

Scientists from the University of Bath have revealed what may very well be the first law of evolution, which has a huge importance. The study was published in Proceedings of the National Academy of Sciences and it shows the fact that evolution drives animals to become increasingly more complex. They analyzed fossils from the crustacean […]

Healthy Rivers Needed To Remove Nitrogen

Nature has its own way of protecting itself, and we should have already learned this (the hard way), because so many catastrophes have happened as a result of man’s destructive work. Look at the damage caused by the recent tsunamis; they would have been almost neglectable if we hadn’t destroyed the plankton, which has a […]

Tiny Pacific skeletons lead to hobbit debate

[digg-me] [reddit-me]After it was proved that Homo floresiensis (”Man of Flores”, nicknamed Hobbit) is a different species than humans, the tiny skeletons found in the caves of the Pacific islands of Palau let to the theory that similar remains found in Indonesia are a very unique species. The Palau skeletons which are from 900 and […]

Major advanced in biofuels: trash today = ethanol tomorrow

Researchers from the University of Maryland started researching some characteristics of bacteriae from Chesapeake Bay that could lead to a process of converting large quantities of all kinds of plant products (including leftovers and trash) into ethanol and other biofuels. This sounds pretty dreamy but it’s quite possible as the technology is not at all […]

Can a butterfly (or moth) remember life as a catterpillar?

As you know (or at least should know), butterflies and moths are known for their metamorphosis from catterpillars to their adult form. This radical change involves not just a change of look, but it also includes changes in lifestyle, diet, sensorial impulses and many many other differences. So it would seem very probable that the […]

Frog Could Offer Diabetes Treatment Hope

About 2.3 million diagnosed with diabetes just in the UK, and it’s estimated that some 750.000 people have it but don’t know yet. Most of them have diabetes type 2, which is caused mostly by obesity and usually develops in middle age. Type 1, or insulin-dependent diabetes, is a less common autoimmune disease that results […]

Enormous Jurassic Sea Predator, Pliosaur, Discovered In Norway

About a year and a half ago, the Natural History Museum in Oslo, Norway had announced the discovery of one of the largest dinosaur-era marine reptiles ever found; we’re talking here about a 15 meters (50 feet) feet long sea predator known as a pliosaur. This fossil (of over 150 million years of age) was […]

Life Encyclopedia; too popular for its own good?

The idea of a comprehensive encyclopedia has been launched a long time ago, and the internet was the perfect way to make it possible and to promote it and make it popular. The internet has done its job too well, because the computers which hosted the encyclopedia were overwhelmed and couldn’t keep it alive when […]

Mysterious compound could in fact be the key to ocean life

To understand this, you need just a very basic knowledge of chemistry, nothing fancy. When small parts of organic matter break down, they could go into rivers or ponds where they could cause a buildup of yellow-brown organic matter that amasses as the tiny plants die. Of course, this matter decomposes into something which is […]

Sharks in peril: the world's fiercest predators cornered, almost extinct

A long time ago, sharks had no natural enemy; they were on top of the trophic chain. All this has changed when man entered the chain, and suddenly (in geological terms) there was no animal safe; some were forced into extinction, many more were threatened, and all feared dire days. Although this may sound a […]

Rare red squirrels halt industrial project

This could be the plot for a Dr. Doolittle movie, without the talking to animals. Things were as follows: The villagers (from Carrbridge, Scotland) were upset because Tulloch Homes, a developer, had an industrial plan to build houses and destroy a part of the forest and wildlife, and which would increase the population by a […]

Tiny Pterodactyl Fossil Found

The pterodactyl derives from the word Pterosaurs, which means “winged lizard”. Pterodactyl means in fact “winged finger”. When you hear about them, you think about some huge, majestic creature, gliding and searching for its next victim. Don’t think that way any more! A fossil suggests that about 120 million years ago, a pterodactyl so small […]

Origin of birds still debated

Birds evolved from lizards, (nearly) all scientists agree about that, but strangely enough there is still a debate around when the first bird showed up in the Mesozoic scene. While paleontologists who have studied fossils think that birds evolved from dinosaurs about 60 million to 65 million years ago, right when the dinosaurs went extinct, […]

Nanostructures give butterflies wonderful colours

Butterflies have fascinated people for as long as we can remember; the beauty of their wings is known to just about everybody and well just about everybody loves them. But behind their naive beauty lies a mistery which has baffled scientists as they couldn’t understand how these colours are created. Marco Giraldo has been examining […]

The tree of life just lost a branch

The tree of life is a metaphor scientists use to describe all life on Earth in an evolutionary context. Charles Darwin talks about envisioning evolution and ecosystems as a “tangled bank” in The Origin of Species; however, the book’s sole illustration is of a branched diagram that is very tree-like. This “design” has been used […]

How to recover from a mass extinction

About 250 million years ago, at the end of the Permian, and event caused a mass extinction which killed over 90 percent of the life on Earth. Ecosystems were destroyed and organisms were left to recover; it was the closest life came to being wiped out ever. The full recovery of those ecosystems took at […]
