It seems rather obvious to me, but there was a lot of debate regarding how a country’s politics affect its emissions – for better or for worse. A new study published in the journal Proceedings of the National Academy of Sciences found that environmental policies in the US have had a significant impact on emissions from 1990 […]
Sampling impact glass from the ancient craters that litter the surface for Mars might prove key to settling a long debate: did Mars ever harbor life? Researchers at NASA believe this is a great lead after the Mars Reconnaissance Orbiter (MRO) currently hovering above the red planet found deposits of glass. These were formed by impacts with large asteroids, whose blast trapped and preserved any matter it came across: dust, soil or any plants or bacteria (if there ever were such things). Cracking open these glass time capsules and peering inside could, thus, be one of the best places to look for.
The U.S. Fish and Wildlife Service reports it has classed all chimpanzees, whether captive or wild, under the Endangered Species Act. Previously, chimpanzees kept captive in labs for biomedical research, entertainment or as pets were classed as "threatened".The USFWS director Dan Ashe agrees that this has transmitted an erroneous mixed message to the public. Whether captive (and hopefully cared for) or living in the wild, all chimps belong the same species, and this species is definitely endangered and in dire need of help.
A new project started by Green Energy Africa in September 2014 has brought solar energy to 2,000 homes in Naiputa county alone, and put new power into the hands of women who sell affordable solar installations.
Known to feed mainly on seals, the images Jon Aars at the Norwegian Polar Institute captured of a polar bear dining on dolphins is a "culinary" first for the species. The photographs were taken in the Norwegian High Arctic, mid-April 2014. The bear was seen feeding on the carcass of one white-beaked dolphin, and covering another with snow.
Since the time of the ancient Egyptians, people have using the grounded seeds of the Moringa oleifera tree to clean water. Scientists found that some of the proteins contained in the seeds interact with the bacteria in the water, killing and clustering them. Eventually, the bacteria lump falls down to the bottom of the watery solution, and makes the water safe to drink. Now, a team at Penn State reports it's uncovered the mechanism that allows the "miracle tree" seeds, as they've been called before, to purify water. In those places of the world where there isn't any access to clean water (850 million people), the moringa might hold true to its name and provide a cheap, sustainable solution to the problem. Just grow your own water filter and decontamination "device".
In a breakthrough moment, researchers at MIT successfully cooled sodium potassium gas molecules (NaK) near absolute zero. At this temperature, matter behaves significantly different and starts exhibiting quantum effects. This is the coldest any molecule has been recorded ever.
Later last year, ZME Science revealed that one of Elon Musk's top priorities in the future is deploying a massive fleet of micro-satellites into Earth's low orbit to provide internet and mobile data. The plan is to serve internet to billions in the developing world, but to do so the service needs to be very, very cheap. At the same time, while launching thousands of satellites into space doesn't sound particularly cheap, but if there's any company good at launching cargo into space affordably that's SpaceX. This isn't exactly a pipe dream, and Musk seems very serious about it considering he just filled an official request to the FCC to gain permission for a test of the satellite internet, according to the Washington Post.
The development of a method that would allow for metals to be used in 3D printing would open up a huge range of new possibilities, as the robustness and good thermal and electrical conductivity of metals lend well to a number of fields, such as microelectronics. A team from the University of Twente has developed a way to print 3D structures out of copper and gold, by using a pulsed laser to melt a thin film of metal and stacking the small droplets.
A recent study involving a Papua New Guinea tribe that practiced cannibalistic funeral customs sheds new light on prion-related conditions such as mad cow disease.
Around 80,000 people around the world answered a questionnaire that gauged what they valued most in life. Their responses were centralized and normalized by the OECD Better Life Index, and used to design an infographic. Labeled over each of the 180 countries, you can see what’s the dominant life priority of the population.
Daimler, the giant auto maker from Germany, is releasing its own version of a large-storage battery on the heel's of Tesla's heralded Powerwall. Branded under Mercedes-Benz, the battery pack is destined for both automobiles and home use. So far, a 2.5 kWh each version has been made public, with Deimler claiming it can be packaged in up to eight modules bringing the total capacity to 20kWh worth of energy - more than enough to power a typical home or even a small business.
It's nothing new to hear about chimps or monkeys drinking alcohol, most often stolen from unsuspecting tourists, but a new research which documented the chimpanzees of Bossou, south-eastern Guinea, for the past 17 years found some engage in habitual drinking. It's the first evidence of habitual drinking outside humans. Like humans, some enjoy the brew more often than others, while some totally abstain from the habit.
Converting the power infrastructure to rely on clean, renewable energy seems like a daunting, expensive and some would say, unachievable task. But Mark Z. Jacobson, professor of civil and environmental engineering at Stanford, and his colleagues, including U.C. Berkeley researcher Mark Delucchi, are the first to outline how each of the 50 states can achieve such a transition by 2050.
The SpaceX Dragon crew capsule's milestone safety state which took place the other day passed NASA's approval board. Back then, the capsule was launched atop a trunk powered by eight SuperDraco engines to a height of 1,187 meters (3,900 feet) at 345mph. The capsule then separated from the trunk and deployed three parachutes that touched it down for a splash in the Atlantic, very close to shore.
Computers and water don't mix well, but that didn't stop Manu Prakash, a bioengineering assistant professor at Stanford, to think outside the box. Using magnetic fields and droplets of water infused with magnetic nanoparticles, Prakash demonstrated a computing system that performs logic and control functions by manipulating H2O instead of electrons. Because of its general nature, the water clock can perform any operations a conventional CPU clock can. But don't expect this water-based computer to replace the CPU in your smartphone or notebook (electrons speed vs water droplet - not a chance). Instead, it might prove extremely useful in situations where logic operations and manipulation of matter need to be performed at the same time.
Engineering microorganisms may be the key to solving major environmental problems, particularly the accumulation of greenhouse gases and fossil fuel overconsumption.
Traces of soft tissue and red blood cells were discovered by accident by a team of paleontologists and biologists while they were playing around in the lab with so-called "crap" fossils dug up more than 100 years ago in Canada. Usually, museum curators are very proud and picky about the works they display or hold in storage, and any analysis that involves breaking or sectioning a fossil is most often than not strictly forbidden. But these fossils - like a claw from a meat-eating therapod, the limb from a duck-billed dinosaur and even the toe of a triceratops-like animal - were fragments in poor conditions that nobody really cared about. One man's trash, another man's treasure.
A group at the Cornell Lab of Ornithology developed a sophisticated facial recognition software specially designed to identify birds for photos. Called the Merlin Bird Photo ID, the software works its magic by employing a combination of image recognition algorithms, deep learning techniques (so it learns from its mistakes and gets better in time) and human collaborators who upload photos and help the software by first identifying the key features that makes a species distinct. The team is now working at turning the software into an app, so that anyone with a smartphone can take photos of a lingering avian wonder then instantly come to know which species it is.
There are some important issues nowadays in which scientists and laymen seem to disagree on. For instance, there's climate change. While the world's leading climate scientists agree with 95% confidence (very very very likely) that the world's climate is changing in an accelerated manner due to greenhouse emissions as a result of human activities. But only 50% of Americans agree that global warming is happening and is caused by humans. Then there's the age old Darwinism vs creationism schism. A major survey found that 31% of the US public believed that humans had existed in their present form since the beginning, with a further 24% stating that humans had evolved under the guiding hand of a supreme being. In contrast, only 2% of AAAS scientists said humans had not evolved in their time on Earth. Of course, then there's the case of doctors vs so-called anti-vaxxers - people who refuse to vaccinate themselves or their children because they think these cause illness, not ail or prevent it. But maybe one of the most heated debate in which scientists and the public is mostly opposed concerns genetically modified organisms (GMOs).
Canadian paleontologists discovered a new dinosaur which looks strikingly similar to the famous Triceratops. While the two are very similar in many respects, the new species stands out due to the size and shape of its facial horns and the shield-like frill at the back of the skull. It also had a longer nose horn than Triceratops, and two small horns above its eyes. The radiating frill and pentagon-shaped plates must have made the dinosaur look like a crowned Triceratops. Once you consider this, it's not surprising how the team named the new dinosaur Regaliceratops peterhewsi (regal is latin for royal, and Peter Hews is the paleontologist who first discovered the fossils).
Seven miniature species of frogs living on seven different mountain tops sounds like the premise for the next Kung Fu Panda sequel. But as researcher Marcio Pie of the Federal University of Parana and his colleagues show in a paper published in PeerJ., it is what they have found in the Atlantic Rainforest of Brazil.
The nature of bright swirl patterns, some extending for hundreds of kilometers, on the moon's surface has eluded researchers for years. Now, the mystery seems to have been solved after a computer simulation suggests these were made following comet impacts. The tails of the comet, through made up of light-weight ice particles, likely blew off the upper, dark layer of the moon's surface, leaving behind a bright trail.
Paleontologists have discovered the wonderfully preserved fossil of a prehistoric bird which flew through the forests of the ancient supercontinent Gondwana, some 115 million years ago. The humming bird-sized bird had a spotted, ribbon shaped tail. The remains were discovered in a sedimentary hotspot in nowadays Brazil. It's the first of its kind discovered in South America and one of the oldest birds discovered from Gondwana, a supercontinent that once encompassed Africa, Antarctica, Australia, India and South America.
Geoscientists have finally unraveled one of Greenland's long-standing mysteries: how billions of gallons of water can drain in a matter of hours. They believe that this might also help us better understand how sea levels will rise in the future.
With NASA's New Horizons shuttle basically knocking on Pluto's door, Mark Showalter and Douglas Hamilton present new theories on Pluto's moons and make predictions about what New Horizons will observe. They propose complex interactions and an intricate "dance" of Pluto's moons - a miniature version of our solar system.
Microscopic swirls from gold might be the key to protect your cash and credit cards in the future, making identity theft virtually impossible. Researchers at Vanderbilt University developed the "Archimedes spirals" and report that they produce four times more blue light per unit volume than currently existing frequency amplifiers; they could be printed on currency, ID cards and pretty much everything that's important to prevent counterfeiting.
The Center for Science in the Public Interest, a nonprofit health advocacy group based in Washington, DC, just released its Xtreme Eating Awards. Hint: it's not that kind of award you want to win or even get mentioned. CSPI officials ranked the highest calorie, fat-rich meals served in restaurants across the country. This year, they say, they've been completely blown away by what they found on the table served to Americans.
Researchers at the University of Wisconsin-Madison designed an innovate and sustainable solution to the global electronic waste problem: make the substrate of computer chips out of cellulose nanofibril (CNF), a biodegradable material from wood. The team collaborated with the the Madison-based U.S. Department of Agriculture Forest Products Laboratory (FPL) to build their device.
After the Large Hadron Collider (LHC) took a 2 year hiatus to up its power, it's finally back, and it's stronger than ever - strong enough to uncover some of physics best kept secrets. Today, June 3, the LhC started delivering physics data for the first time in 27 months.
The island country is preparing to launch a new energy policy, seeking to curb costs and promote the use of environmentally friendly sources of power.
In its “Energy Security and Sustainability Strategy” (ES2 Strategy) report, the US army outlines the steps it should take to increase resilience and adapt to an ever changing world. Energy makes the go world round, and for an army it's literally a matter of life and death. Not surprisingly, the authors note given the current climate of affairs the "army will prioritize solutions that reduce multiple resources. The Army can use energy more efficiently by purchasing energy efficient products, modernizing buildings and utility systems, purchasing energy efficient vehicles, and using more renewable/alternative energy sources." Basically, being dependent on a finite resource (oil) is a security vulnerability, which isn't something new. Military strategists have been aware of this for a long time - maybe the most during WWII when many lives were claimed in battles over oil rigs in North Africa and the Middle East, and oil refineries were being bombed on the clock. What's changed today is the feasibility of renewable energy sources. Drawing the line, in those situations were oil is a liability (and we can only expect these to become ever numerous in the future), it'll be scrapped in favor of renewable energy systems, both for generating and storing energy.
It almost looks too futuristic to be true, but the prototype was already developed. London-based ecoLogicStudio has taken this innovative concept and made it a reality at the Milan 2015 Expo. Using only the Sun's energy, the Algae Folly is the perfect intersection of technology, design... and food.
Rooftop solar is now cheaper than grid electricity for 30 million people living in 6 cities, a new report writes - even without government subsidies. This includes the cost of installing the solar panels. In other words, the future is here - solar energy is cheaper than the alternative.
A simple, cheap device could extend disposable battery life eight-fold; it suits all batteries from AAA to D and it works by keeping its voltage boosted to just above what most appliances consider ‘dead’. The technology was developed by US-based start-up, Batteroo and it’s called a ‘Batteriser’. It basically comprises of a very thin stainless steel sleeve (0.1 mm) that […]
The rate of melanoma, the most dangerous form of skin cancer, has more than doubled in the past three decades - and is on track to increase even more. With the Summer closing in, CDC researchers urge people to take more protection from ultraviolet rays.
The Houston Museum of Natural Science is one of the most impressive in the world, curating rare and indigenous wildlife from Texas, a huge sundial and one of the biggest paleontology halls. As expected in a city with some of the richest geologists in the world, we can also find here a large exhibit of over 750 crystallized mineral specimens and rare gemstones. Among these sits the "crown jewel", a 1,869-carat natural emerald crystal, the largest ever discovered in North America.
Fifty years ago today, on June 3rd, 1965, 19:46, astronaut Edward White pushed away from the Gemini 4 capsule and into history as the first American to walk in space. Although a Russian had been the first to float in space, Ed White was determined to be the first to use jet propulsion to actually maneuver himself […]
They call it "Tree 76", because it stands 76 meters tall (249 feet) above the Muir Woods floor in California. Researchers wanted to see how old Tree 76 is, and they were surprised to see how young it is - at only 777 years old, it's much younger than the oldest known trees of its kind.
Chimps not only have the brain power to understand the concept of cooked food, but they are willing to delay eating raw food if they know they can cook it. This highlights impressive cognitive abilities, such as the foresight and patience to resist their urge of eating food.
Swiping your phone’s touchscreen might disappear just as quickly as it emerged, if Google have their way. When their new technology hits the shelves, you won’t even have to touch a screen ever again. Here’s why. It’s called Project Soli, and it uses radar waves to detect precise finger movements – or as they call […]
We've all seen them - the food pics are everywhere. Instagram has basically become a food porn haven, with everyone sharing their delicious lunch or snack. But those pics could actually yield valuable information, and tell you how many calories you're eating.
Tired of cooking your own food, hiring help or eating out? Tired of eating, for that matter? Just kidding. The last one might be for another cyberpunk story. Today, however, I present to you the first robotic chef in the world. For an one time (most likely very hefty) fee, you too could have your very own gourmet chef, at your disposal 24/7. Using its fine mechanical arms, the chef bot from London’s Moley Robotics could potentially cook any kind of food. For instance, at the Consumer Electronics Show (CES) in Shanghai this past weekend the robot chef cooked and served crab bisque (soup). Right now this is the dish it knows how to make, but once it'll start shipping it should come complete with 2,000 recipes, according to the developers.
A pair of anthropologists compared the anatomical features o bonobos to those of homo sapiens and other apes to infer any clues that might help us understand how we evolved to look the way we do.
In the beginning, the Earth's surface was a lifeless, hot, but chemically rich place. In these harsh conditions, the first amino acids synthesized from inorganic compounds, and from them, proteins formed. They built the first single cells, which went on to form plants and animals. Recent research helped us understand the process that created amino acids, and there is a widespread consensus in the scientific community as to the path cells took to evolve to complex life as we know it today.
A team of biologists from Queensland discovered two new species belonging to a marsupial genus known for mating until it literally dies. The antechinus marsupials look like pouched mice or shrews, but as cute as they may look, they're real beasts in the sack. Typically, once the breeding season starts, males embark in vicious sexual orgies 14 hours at a time, and it doesn't stop for two or so weeks. At the very end, the males suffers from diseases, internal bleeding, their fur falls off and some get ulcer. Ultimately, all that whole lotta love kills them, and rather painful too. Though they've just been discovered, the new antechinus species are considered endangered by the researchers.
Speaking at the event that celebrated his 50th year as a fellow at the University of Cambridge’s Gonville and Caius college, Stephen Hawking expressed his doubts whether a young student of similar talents, as well as disabilities, would receive the kinda of support he had. The renowned physicist, now 73 years old, has been living for the past decades with a devastating motor neurone disease that doctors believed would kill him while he was still in his early 20s. His determination to live on despite being confined to a wheel chair all his life is inspiring, but it's unlikely he could have survived to live this day were it not for his fellows and support at Caius College; nevermind his outstanding achievements in physics.
The entire world is expecting the results of the Paris Climate Conference - will a global treaty finally be reach, or will it be another round of discussions and promises with no pro-active solutions? The French Foreign minister believes that if we are to reach a climate deal, it has to be phrased in such a way that it doesn't require approval from the US Congress. Laurent Fabius said:
A couple of simple gadgets, like a smartphone or low-res camera, along with a couple of sensors were powered wirelessly using a simple Wi-Fi router you can find in any home. Moreover, not only were the gadgets remotely powered, the router also continued to transmit Wi-Fi signals unobstructed. This simple, but powerful demonstration gives to show how the so-called "Internet of Things" might grow to turn your home into an over-sized smart gadget.
If we want to defeat cancer, we have to treat every patient uniquely, a team from the National Cancer Institute (NCI) concluded. They announced the trial of a new type of cancer test – one that is designed for the patient, not for a specific condition. “This is really the first time in a very large way […]
