They like freezing conditions, but the Emperor penguins struggled during the last Ice Age, a new study concluded. In fact, if they hadn't been able to change their breeding habits and even their genetic make-up, they might have not survived.
We all know how therapeutic and soothing (or on the contrary, motivating) music can be; and we all know that different people like different types of music... so it seems safe to say that different animals also like different types of music. Now, a joint team of scientists and musicians believe they found how to compose the purr-fect music for animals, including monkeys and cats.
Mars - our neighbor, the Red Planet... is not actually red. The first look at what’s under Mars’s dusty red surface has revealed a clearly greyish blue rocky layer.
The world's first grid-connected wave power station has just been activated off the coast of Australia. Taking energy directly from the waves and sending them to the grid is a remarkable achievement which will hopefully be replicated in Australia, as well as in other parts of the world.
If you've ever wondered what happens inside an egg, then science has you covered - researchers have developed transparent artificial eggshells; but they didn't do this just out of curiosity - they want to create a controlled environment for bird embryo growth and development to aid stem cell studies.
Scientists at the University of Sydney in Australia have achieved 5G speeds of 1Tbps, far exceeding existing the speeds of existing technologies. At 1 Terrabyte per second, you could download 10 movies per second.
After an exhaustive analysis conducted over a year and a half, NASA's Curiosity Rover has finally confirmed the existence of methane on Mars, somewthing which indicates that life may have existed (or still exist) on Mars.
This gentle and secluded creature is called a pangolin. Bet you've never heard of him. It looks sort of like a walking pinecone, a dragon or a dinosaur. It's tongue is as long as its body and can curl, then roll in a scaly ball. It's a pretty amazing animal and it's a shame so few people know of its existence. But more worrisome is that the pangolin might cease to existence entirely, with or without we knowing about it. Many believe it's the most trafficked animal in the world.
Memories aren't infallible - even for those with photographic memory - so, more often than not, they'll seem fuzzy. And the older these get, the fuzzier they're recalled. Mixing names, faces and events in your head can sometimes be embarrassing, but at least we're not alone. Seems like bees have false memories too, according to a study made by British researchers at Queen Mary University of London. Previously, false memories had been induced in other animals, like mice, but this is the first time natural false memories have been shown to happen. Research like this might help us, in time, understand how false memories are formed and, in a more general sense, how we recall events.
One of the prime arguments climate change skeptics throw about is how surface temperatures have remained more or less constant for the past 15 years, hence there is no man-made global warming – it’s all a sham, a conspiracy to keep scientists busy with gratuitous grants and fill Al Gore’s pockets. I’ve written previously about […]
Like most things in our modern day life style, we tend to take vaccines for granted. Some, in ever growing numbers, are on the contrary pushing and inciting against vaccination for all the wrong reasons. It’s easy to forget, however, that since their introduction hundreds of millions of lives have been spared. Vaccines given to […]
A complex artificial intelligence program developed by DeepMind, a London-based company which was acquired by Google last year for $400 million, mastered classic ATARI video games, like Breakout, Video Pinball, and Space Invaders. It was so effective that it outperformed professional game testers in 29 of the 49 games it tried out. As is the case with such demonstrations, there's more to it than just humiliating humans. The same algorithms could be used to develop and improve autonomous robots or self-driving cars.
Paleontologists have excavated and analyzed the remains of an ancient hypo ancestor in Kenya. The 28 million-year-old fossils paint a broader picture revealing the missing link between modern day hippos and the earliest ancestor who lived some 53 million years ago. As an interesting tidbit, the closest living relatives of the hippo are whales and […]
Building vertical farms is innovative and can have significant advantages, done properly; but building a vertical farm in the middle of a city... that's just awesome! In downtown Jackson, Wyoming, developers are working on a vertical veggie farm which just might revolutionize urban food growing.
A while ago I wrote that the applications for graphene are endless, and it seems like scientists just want to make prove me right - University of Manchester scientists have used graphene to target and neutralise cancer stem cells while leaving healthy cells unharmed.
A partial skull fragment found in Kenya seems to indicate that early humans were much more diverse than previously thought. The 22,000-year-old skull clearly belongs to a human species, but is unlike anything else previously discovered.
Rats remember acts of kindness done by other rats, and are more helpful to individuals who previously helped them. It's not clear if they do this because they are grateful or if they are trying to make sure that they will get helped in the future as well, but their behavior gives scientists a new understanding of animal social behavior.
It's pretty scary what modern medicine can do these days. Sergio Canavero of the Turin Advanced Neuromodulation Group in Italy announced his intention to perform a full head transplant by 2015. He will put forth a proposal at a conference in the US so interested parties can get onboard and make suggestions for the procedure.
Astronomers have discovered a humongous supermassive black hole that’s 12 billion times as massive as the Sun. What’s peculiar about it isn’t necessarily its mass – some even bigger black holes have been found – but rather its age. Observations suggest that the black hole 12.8 billion light-years away, which means what scientists are reading […]
A typical school cafeteria serving contains fried food stuff like nuggets, mashed potatoes or peas. Kids' nutritional uptake and diet could be a lot better, as proven elsewhere by schools all around the world. Sweetgreen, a restaurant the values local and organic produce, recently published on its Tumblr an amazing photo journal detailing what a typical cafeteria serving looks like in countries like South Korea, Brazil or Italy.
Norwegian rats know how to keep their friends close. A new study found they reward other rats for their help even though there's no immediate gain at hand as a result of this behavior. Called direct reciprocation, this is the first time something like this has been recorded by science outside human interactions.
Two new studies - both covering gay men, one in Britain and the other in France - were recently shared with the public boasting terrific results. In the trials, gay men were asked to take a drug called Truvada either daily or right before and after having sex. In an unlikely event of chance, both studies found a 86 percent reduction in new HIV infections among volunteers using Truvada. This suggests that the orally administered drug might be a lifeline in many HIV-ridden communities, considering 90% of all HIV cases could be prevented if those infected seek treatment.
The highlight of the award winning film, "The Imitation Game", is when Alan Turing and colleagues devise an ingenious statistical method that eventually helped decipher the Nazis' Enigma code. This breakthrough allowed Allied intelligence to read previously unavailable German military positions and actions, vastly shortening World War II. Interestingly, a team of neuroscientists at Columbia University found that more or less the same statistical method applied by Turing and co. is used by the brain to make any kind of decision, be it going left instead of right in an intersection or placing a higher bet during a high raise power game instead of folding.
Bionic hands - artificial limbs controlled through thought power - they're as awesome as they sound, and they're now a reality. Three Austrian men have become real-life cyborgs after having losing their hands to injury and then undergoing innovative surgery.
Humans have been fascinated by eyelashes for centuries, with long and luxuriant eyelashes being in fashion since the days of ancient Egypt. Now, researchers have found how eyelashes actually work, what their functions are, and revealed that longer is not necessarily better.
If you've ever walked with beverages in your hand, you probably know that coffee tens to spill easily, while beer doesn't. Emilie Dressaire, an assistant professor of mechanical and aerospace engineering at the New York University Polytechnic School of Engineering, believes the secret lies in the foam.
The Curiosity Rover, currently on Mars, took another selfie in the "Mojave" area, where it is preparing to have a second taste of Mount Sharp, the central peak within Gale crater. The selfie scene is assembled from dozens of images taken by the Mars Hand Lens Imager (MAHLI) camera on the rover's robotic arm.
The Sahara Desert and the Amazon area have few things in common - one is a dry, barren wasteland, while the other is the most fertile area on Earth. But according to a new NASA study, there may be more than meets the eye when it comes to the two - dust from the Saharan area makes the trans-Atlantic journey, fertilizing the Amazonian rainforest with phosphorus.
The love hormone, oxytocin, was found to neutralize the motor deficiency effects of alcohol in rats, sobering them up. The researchers involved believe that given enough oxytocin, similar sobering effects might be seen in humans as well.
Contrary to popular belief, much of the damage inflicted to the skin by harmful ultraviolet (UV) light occurs hours after exposure to the sun, even when you're sitting comfortably asleep in your dark bedroom. The Yale University research also made a startling find: melanin - the pigment that gives human skin and hair its colour - has both carcinogenic and protective effects. This double standard should be taken into consideration from now on when discussing UV exposure, but also when looking for new treatments to skin cancers like melanoma.
It's always the cute ones - a team of Norwegian researchers found that the Black Plague, which arrived in Europe in the 14th century and wiped out up to 200 million people was brought by gerbils, not by rats.
The carnivorous bladderwort (Utricularia gibba) a carnivorous plant which occurs fresh water and wet soil. Recently, they took biologists by surprise by having a huge number of genes, despite a fairly small genome. The plant is six times smaller than the grape for example, but has 28,500 genes, compared to the 26,300 of the grape.
A new study has concluded that marijuana is much safer than alcohol and tobacco combined. Alcohol is actually the most dangerous substance out of the ones studies - more dangerous than heroin, cocaine, ecstasy or meth.
Using CT-scans, researchers at the Netherlands-based Drents Museum imaged a mummified monk who lived 1,000 years ago inside a Buddha statue. Encased inside the golden cast, lie the the remains of Buddhist master Liuquan of the Chinese Meditation School. His organs were removed prior to becoming encased, which isn't a surprise being a standard mummification practice. What was surprising however were the rolls of paper scraps covered in Chinese writing which were placed where the organs used to sit.
In 2000, the American Academy of Pediatrics advised parents to keep children as far away from peanuts as possible, in order to avoid potential allergies - it seemed like a good idea at the time. But now, a new study has found that in the long run, that actually did more harm than good, and if we want to fight allergies, we should be feeding our children peanuts.
Stanford scientists proved that it's possible use DNA minirings that code the production of a specific protein that can't be found in healthy cells to diagnose any form of cancer. The mini-rings were injected in the bloodstream of mice and allowed for accurate diagnosis up to two days from the injection. In authors envision using the same solution to diagnose any cancer in humans, while also relaying how large is the extent of the tumour. Moreover, they hope they can achieve this with an orally administered pill, instead of an intravenous injection, thus making it the least invasive form of cancer diagnosis. The only pain you'll experience is when doctors will prick a needle in your finger to get a drop of blood. Take that, biopsy!
A company called nanoFlowcell has revealed a concept sports car which gets its energy from salt water and can run up to 621 miles on this electricity alone - wow!
Almost 70% of HIV-infected people in the US are either undiagnosed or not receiving care; this population is responsible for 91.5 percent of all infections, according to the CDC.
In the quest to understand what are the crucial differences between human and chimpanzee brains, scientists have isolated a stretch of DNA, once thought to be “junk”, near a gene that regulates brain development in mice. The engineered mouse embryos grew significantly larger brains. Those which received human brain DNA strands had 12% larger brains than those bred with chimp brain DNA. Research like this, though ethically controversial, might help identify which DNA sequences give a brain human characteristics, but also aid in findings treatment or cures for brain diseases like Alzheimer's.
Mollusks such as oysters, clams and scallops are highly vulnerable to the increasing acidification of the world's oceans. A new study concluded that the acidification is so intense that the mollusks aren't able to properly produce a hard shell, putting them in peril.
Paleontologists diving beneath the surface of a water-filled cave in Madagascar made a monumental find: a graveyard filled with the bones of a wide variety of species,some very rare, other extinct for hundreds, if not thousands of years. Some of the remains that dot the bottom of the Aven Cave in Tsimanampetsotse National Park include those of the extinct elephant bird, a flightless giant similar to an ostrich, but most bones belong to the long-lost giant lemurs.
Jupiter's satellite Europa is definitely one of the most interesting places in our solar system - despite being really far from the Sun and frozen on the surface, NASA researchers actually believe it is the best bet to search for extraterrestrial life. Now, scientists and engineers have actually planned a mission aimed to reveal whether life on Europa exists or not.
Here’s another reason for children to do their chores: washing dishes by hand boosts children’s immune system. The findings were reported by Swedish doctors who found that in households where dishes are washed by hand children have much fewer allergic incidents than in those where the dishes are washed by a machine. Yet again, the findings […]
“I am getting sick and tired of dinosaurs being forced on our children.” You just know something’s up when you hear that kind of phrase. Apparently a group of concerned Christians stood up against what they believe to be the grand conspiracy of scientists: shoving dinosaurs into the world so they can make money. I’ll […]
Wei-Hock Soon, an aerospace engineer and a part-time employee at the Harvard-Smithsonian Center for Astrophysics is one of the few respected scientists who spoke against the general consensus that human activity is a significant contributor to climate change. He has published 11 papers on climate change since 2008. However, it was recently shown that he received $1.2 million from oil companies in exchange for his "science". According to leaked documents, the papers were simply “deliverables” that he completed in exchange for their money. He used the same term to describe a testimony he prepared for Congress.
The mighty Aztec capital of Tenochtitlan wasn’t all that different from New York City today, or any major city for that matter, despite the former has been deserted for 500 years. You see, both cities grew under the same rules, independent of political or economic systems, according to a new model. Scott Ortman, an anthropologist at University of Colorado, Boulder, heard […]
Marine animals today are 150 times larger than they were 540 million years ago, according to a new study which seems to suggest evolution favors animals bigger in size.
A new report highlights the reprehensible state of women working in STEM fields—science, technology, engineering, and mathematics— where they’re not only under represented, but also under constant pressure to over perform. The report also stresses how sexism and racism is “still a thing” in labs, universities and technology companies. In fact, there’s seems to be […]
Here's a question: what's the difference between actor Sean Penn and the charitable Mother Theresa? Bear with me for a second. Here's a bit of context: following the onslaught left by Hurricane Katrina, Penn hurried to New Orleans to aid victims. Allegedly has has personally saved 40 people. Today, however, he's scorned and mocked of because he also brought a camera crew and publicist along for the ride to document his humanitarian effort. Both Mother Theresa and Sean Penn have engaged in what can be described as humanitarian aid, yet one's seen as a saint, while the other is made fun of. The key difference is motivation and now game theory may finally be able to account for it.
In an attempt to make programming more attractive, MIT has developed a stunning “robot garden”, dozens of fast-changing LED lights and more than 100 origami robots that can crawl, swim, and blossom like flowers. I’ll tell you, if this doesn’t make kids want to code… nothing will! The “garden” was created by a team from MIT’s Computer […]
