The U.S. Fish and Wildlife Service has rejected a proposal to list North American wild horses as threatened or endangered, arguing that a horse is a horse, wild or tame, and proponents have failed to show how the behaviour of wild horses differs from that of domestic ones. The number of North American wild stallions has […]
MIT engineers demonstrated a working spectrometer that took a huge leap in scale from a huge, bulky lab gear to a portable piece of equipment that's small enough to fit in a smartphone. Spectrometer are essential to research nowadays, employed in everything from physics, to biology, to chemistry. To design the spectrometer, the MIT team made use of tiny semiconductor nanoparticles called quantum dots. Having a portable spectrometer could prove to be extremely practical .You can use it to remotely diagnose diseases, detect pollution or food poisoning.
In 2000, the CDC declared measles as eradicated in the US, meaning there was no more endemic transmission. That doesn't mean though, that it can't creep out from time to time, especially in communities where heard immunity is poor because of low rates of vaccination. This is attested by a woman who unfortunately died of the virus, making it a first in twelve years. The woman was taking medications that suppressed her immune system due to other conditions, and this made it very difficult for her body to fight another infection.
Seemingly small and delicate, seahorses are actually much more resilient than they look. Engineers have demonstrated that the seahorses’ prism-like tails are mechanically superior to the cylindrical ones; the discovery could lead to the development of more resilient robots. There are 54 species of seahorses, and while they may be significantly different one from the other, […]
A team led by scientists at University of British Columbia highlights the impacts of climate change on the world's oceans and marine life. Two scenarios were analyzed. One followed the changes that would arise if the world banded together to significantly curb greenhouse gas emissions; the other summarized impacts 100 years from now if we'd go on with business as usual. The report outlines the consequences under each scenario and found immediate action is required if we're to avert at a catastrophic outcome, particularly regarding the planet's oceans.
A team at University of Chicago made the most comprehensive woolly mammoth genome sequencing ever. By comparing its genome with that of its distant cousins, the Asian and African elephants, the researchers were able to determine which are the mammoth's specific genes. These were ran with libraries and repositories to identify what these do. We now know which of mammoth's gene shaped its uncanny skull and small ears, how it got hair to cover all its body or how the mammoth adapted a special fat metabolism and cold coping mechanism. To test their findings, the researchers transplanted a mammoth gene into a human cell. The kidney cell produced new proteins which were tolerant to heat or cold, as suspected showing their other genetic determinations are also likely correct.
Rising temperatures are fundamentally changing the way Australia's bearded lizards get their gender. Basically, the lizard's sex is not dependent on their genes as before, but on temperature. In time, the male chromosome could disappear, as more and more females are bred - the preferred sex. What this means is that if temperatures reach a critical level, then the lizards could become extinct due to lack of males. This has never happened before and it's as scary, as it is interesting.
Rosetta is a robotic space probe built and launched by the European Space Agency. Along with Philae, its lander module, the craft is performing a detailed study of comet 67P/Churyumov–Gerasimenko. The probe usually orbits 67P at a distance of a few hundred kilometers. Footage received from Rosetta over the last year showed a number of dust […]
As the US starts to thaw its relationship with Cuba, important economy, touristic and cultural prospects start to emerge; but as these prospects emerge, so to do environmental concerns. Cuban scientists are worried that as American tourists and money start flowing into their country, the environment will be the one to suffer. “We don’t have […]
In the lab, a team UC Santa Barbara demonstrated that an artificial pancreas that can automatically deliver insulin shots at a regular basis to diabetes patients. The biocompatible pancreas constantly monitors glucose levels and administers the insulin when its needed. This way there would be no need for cumbersome daily insulin injections. The researchers will soon start trials on animal models and if all goes well, clinical trials will follow shortly.
Saber-tooth cats, the bane of early humans (and pretty much every creature that co-existed with them), roamed the Earth for 42 million years before going extinct at the end of the ice age. Now, a new study has found that their trademark teeth may have evolved later in their evolutionary stage, but when they grew, they grew […]
This little iron fish may look like a two bit souvenir, but what it can do is far more spectacular, not to mention useful. When added in boiling water, the fish-shaped object leaches just enough iron to offer up to 75 percent of daily iron needs of a person. Tests so far have proven that this simple, yet innovative the solution helped halve the cases of iron-deficiency anemia in Cambodian communities.
Women's faces are more attractive to men when they hit peak ovulation, past research showed. It's not clear what the amplifying signals are. One suggestion was that women's cheeks turn slightly red during ovulation, providing a subtle cue that enhance attractiveness. Using cameras specially designed to distinguish between subtle colour variations, researchers at University of Cambridge found that women's faces show an increased redness. Peculiarly, this difference is so small that it's not visually perceptible. Is the cue that subtle or can the enhanced attractiveness be attributed to some other factor or signal?
It's the kind of error you never want to pop up in your code: Google’s automatic image recognition software has apparently classified two black friends as 'gorillas'.
The Great Barrier Reef, which stretches 2,000km (1,200 miles) along the coast, is the world’s largest living ecosystem. Environmental groups are pushing to get the reef listed as “in danger” by the UNESCO, so that the Australian government would have to work harder to protect it from various dangers such as pollution, dredging, fishing and […]
Samantha Cristoforetti, an astronaut currently on board the International Space Station was allowed to take some extra food with her (astronauts are allowed to take “comfort food” with them for psychological reasons – a little something that reminds them of home). Today, she’ll be telling us how to make some space tortillas. Cooking in microgravity […]
A breakthrough research found that male and female mice use different cells to signal pain. This could explain why both more women suffer from chronic pain than men, and pain relief medication seems to respond differently in women.
In March, we were telling you about Tesla Motors' new development, a new battery that could take your home off the grid and eliminate one of the major problems associated with renewable energy - storing it. Now, Tesla is already rolling out the new generation with some remarkable feature. The coolest one? Liquid cooling!
A report issued by the World Health Organization and UNICEF states 2.4 billion people lack access to proper toilets. Defecating outdoors bears a significant risk to the fresh water supply and is associated with the death of 700,000 children each year which contact diseases like diarrhoeal.
Low and middle-income countries bear the most deaths associated with sugary drink consumption. About 3 out of 4 deaths related to drinking sugary drinks happen in developing countries. These drinks greatly contribute to obesity, which in turn is associated with Type 2 diabetes, cardiovascular disease and cancers of the breast, colon, esophagus, gall bladder, kidney, pancreas and ovaries.
Despite a huge gap in public acceptance, the theory of evolution and natural selection is not a controversial theory. It is widely accepted by the scientific community and is, in fact, one of the most successful scientific idea in history. Yet, billions of people around the world discard evolution and uphold a creationist view of how humans, other creatures or the whole cosmos came to being. Ironically, it may be the way that our own brains evolved and supported the adaption of our species that supports a natural predisposition towards creationism. This idea is supported by a paper published in Cognition which found persons who rely more on intuition than analytical thinking are more likely to discard evolution and vice-versa.
Last night, Jupiter and Venus nearly converged on the night sky, being so close that you actually don’t need a telescope to see their celestial dance. “Throughout the month of June 2015, the two brightest planets in the night sky, Venus and Jupiter, are going to converge for a close jaw-dropping encounter,”said NASA in […]
Joining sounds together to create a meaningful language was thought to be a human characteristic, but a new study published in PLoS Biology found that blabber birds also developed their own phonetic language, just like we did! Researchers also believe that studying these birds could give us hints of why and how our language evolved to what […]
Deep below ground level, 3,500 feet (1000 meters) down a Croatian cave, scientists have discovered a new species of centipede. They named this incredibly resilient creature Geophilus hadesi – earth loving Hades – in honor of Hades, the Greek God of the underworld and ruler of Hell. Centipedes are elongated arthropods with one pair of legs per body […]
The Great Wall of China, one of the most marvelous constructions on Earth is slowly fading away due to the reckless behavior of humans. The effects of travel and recycling of the stones for other constructions is taking a monumental toll on the Great Wall, and almost 30 percent of the structure is now gone.
NASA is preparing to send a drone to Mars by 2024 - they've already developed a small, lightweight craft that could conduct aerial surveys and identify potential landing areas and zones of interest.
The Apollo program returned 380.05 kg of lunar rocks and soil, and most of the samples are stored at the Lunar Sample Laboratory Facility. The samples of rocks, breccias, and regolith were polished into thin sections, allowing for optical geologic studies to be performed on them.
Whether it’s Meatless Monday, Weekday Vegetarianism or simply cutting down meat consumption – people from developed countries are eating less meat, and it’s already making a difference. Even though some argue that cutting-back-consumption campaigns don’t push enough of a paradigm-shift, we’re already seeing the changes: 400 million animals were spared in the US alone in 2014 because […]
Today, ray-finned fish make up 99% of all fish species, but it wasn't always like this. In an attempt to find out what triggered this spectacular multi-niche dominance, paleontologists traveled back in time sort of speak and analyzed ancient fossils to see what the fish diversity makeup looked like millions of years ago. Intriguing enough, the ray fish practically exploded in their diversity right after the last great mass extinction which occurred 65 million years ago. An asteroid impact wiped out thousands of species, including all dinosaurs. But there was now enough room for other creatures to take their place. On land, mammals started filling in the large-scale niches eventually reaching a dominant position. In the water, it was the ray-finned fish that seized the opportunity.
A study conducted by assistant professor Jessica Gall Myrick, surveyed almost 7,000 people about their viewing of cat videos and how it affects their moods, to try and find out why so many of us enjoy seeing the furry little pets on video.
Just as it seemed Ebola was gone for now, the disease starts to rear its ugly head again; a 17-year old was killed a month after Liberia was declared free of Ebola. Liberian authorities on Tuesday quarantined the Nedowein close to the capital of Monrovia, where the boy lived. The official announcement came quickly after. “Liberia […]
The effects of carbon dioxide (CO2) emissions are great and long reaching - a new study has found that pink salmon in the Pacific Ocean are threatened by increasing ocean acidification.
In a paper published this month in Proceedings of the National Academy of Sciences, a group of scientists explain the process through which plants like mustard came to be - as it turns out, an evolutionary arms race with a caterpillar played a key role.
Some 10% of the energy generated by a car's engine is lost due to friction between tires and the pavement. What if you could harness this lost energy somehow? A group at the University of Wisconsin-Madison in collaboration with researchers in China have found a ingenious way to collect and use this friction energy by effectively inserting nanogenerators into tires.
Just before sport camps and marathon training begins in the US, doctors report a new set of guidelines that should be reviewed to ensure athletes don't consume more water than they should. Drinking excessive amounts of water can result in potentially serious reductions in blood sodium a condition called hyponatremia. Last year, two high school football players died of exercise-associated hyponatremia (EAH). So, what do you need to do to be on the safe side? Just drink water when you're thirsty. If you have to drink in advance for various reasons - say, if you're a marathon runner - keep the excess water at sensible levels.
Paleontologists working in China have discovered fossils of an impressively armored worm that lived during the Cambrian, 500 million years ago. Called Hairy Collins’ Monster, this is one of the first creatures to develop a spiky armor. Today, the 180 species of velvet worms are pretty similar – they have tiny eyes, antennae, multiple pairs of […]
A few days ago, the US supreme court ruled that same-sex marriage was hence forth legal in all states. To mark the occasion, Facebook released the "Celebrate Pride" tool which overlays a low-opacity rainbow over your profile pic. More than a million people changed their profile photos just a couple of hours after the feature was integrated into the Facebook. While its intentions might seem noble, Cesar Hidalgo - an MIT network scientists - doesn't buy it. He says it's all in fact a huge social experiment whose end game is to see how long it takes for you to change your profile pic to something else.
Paired with recent advances in graphene deposition and manufacturing, this sort of tech of could very well end up powering your notebook or phone a couple years from now.
By now, we've all hopefully at least heard of graphene, the new wonder material that promises to revolutionize a swarm of applications. But now, a team of researchers from Finland have predicted the existence of atomically thin, free-standing 2D liquid phase - a liquid analogue of graphene.
Mars has over 250,000 craters created by asteroid impacts, the Moon has millions - too many to count. But the Earth has an atmosphere, which means we're protected against most threats and we have much to be thankful for. But even the craters that we do have are constantly eroded by wind and water, so finding and identifying them is quite a challenge.
Despite what you might have seen or not seen, there are actually some fireflies living west of the Rocky Mountains, though they mostly keep to themselves and are rarely spotted by humans. Every once in a while, people spot some. This time, one undergrad who was busy insect hunting in the Los Angeles County hit the jackpot after he discovered a new firefly species.
A new study has found that monarch butterfly populations have went down at alarming rates in the past couple of decades, going down on average by 80%. In the forests of Mexico, they went down by as much as 90%.
It's not just us humans that dream of a better future - rats do too. When rats rest, their brains imagine a favorable future such as a tasty treat, a new study by UCL researchers found.
Tomorrow, something extraordinary will happen, even though you might not notice it: right before 8 p.m. Eastern time, we will be adding an extra second – a leap second. Aside for being an interesting quirk, this is another reminder that our time isn’t exactly synced with solar time, and every once in a while, we need […]
We seem to be losing the war on elephant poachers, but a new toolset that involves tracing slaughter hotspots in Africa based on DNA taken from ivory might be exactly what law enforcement needed all these years. This way, researchers at University of Washington, in collaboration with INTERPOL, found that most of the ivory seized since 2006 originates in just two areas.
In his book "Do Androids Dream of Electric Sheep", one of my favorite writers Philip K. Dick explores what sets apart humans from androids. The theme is more valid today than it ever was, considering the great leaps in artificial intelligence we're seeing coming off major tech labs around the world, like Google's. Take for instance how the company employs advanced artificial neural networks to zap through a gazillion images, interpret them and return the right one you're looking for when you make a query using the search engine. Though nothing like a human brain, the networks uses 10-30 stacked layers of artificial neurons with each layer doing its job in incremental order to come to an "answer" by the final output layer is finished. While not dead-on, the network seems to return results better than anything we've seen before and as a by-product, it can also "dream." These artificial dreams output some fascinating images to say the least, going from virtually nothing (white noise) to something's that out of a surrealist painting. Who says computers can't be creative?
Studying ants could help us reduce or even eliminate traffic jams, but only if we let go of our ego. Physicist Apoorva Nagar at the Indian Institute of Space Science and Technology found that ants don't have traffic jams, and we have much to learn from them when it comes to using a road.
Today was a bad day for science after SpaceX's Falcon 9 rocket exploded shortly after taking off from Cape Canaveral, Florida. This is the second successive botched mission whose goal was to re-supply the International Space Station, and the third in the past 8 eight months. The Dragon Capsule was supposed to reach the space station with 5,200 pounds of space station cargo, including the first docking port designed for future commercial crew capsules and the custom tailored Microsoft HoloLenses for virtual reality.
Rwanda's Akagera national park will soon be home to seven lions flown in from South Africa. This is the first time in 15 years that lions will set foot in the country after the entire population was wiped out by cattle herders in the chaos that followed the 1994 genocide. The predators will hopefully mate and steadily replenish lion numbers back to a historical level.
Studying the fossil remains of an ancient reptile-like creature, paleontologists gained valuable clues and insights that help explain how turtles got their most uncanny feature: the shell. The newly named species, Pappochelys, Greek for “grandfather turtle", lived some 240 million years ago and fills an evolutionary sweet spot sitting between earlier turtle ancestors and more recently established species.
