With the most unpredictable U.K. general election looming in modern times, how can big data be used to understand how elections are covered by the media? New research has, for the first time, analyzed over 130,000 online news articles to find out how the 2012 U.S. presidential election played out in the media.
The concept of randomness appears across scientific disciplines, from materials science to...
Tiny parasitic hookworms infect nearly half a billion people worldwide, almost exclusively in...
Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists at EPFL have succeeded in capturing the first-ever snapshot of this dual behavior.
Researchers have long sought an efficient way to untangle DNA in order to study its structure under a microscope. Now, chemists and engineers at KU Leuven have devised a strikingly simple and effective solution: They inject genetic material into a droplet of water and use a pipet tip to drag it over a glass plate covered with a sticky polymer.
Everyday experience and psychological studies alike tell us there are two different types of extroverts: The gregarious “people-persons” and the ambitious “go-getters”. A new study shows that these overlapping yet distinct personalities have commensurately overlapping yet distinct signatures in the anatomy of the brain.
It started with a trip to the basement of the American Museum of Natural History in New York to inspect preserved animal hides. Later, Georgia Institute of Technology researchers built a wind tunnel about 2 ft tall, complete with a makeshift eye. By putting both steps together, the team discovered that 22 species of mammals are the same: their eyelash length is one-third the width of their eye.
Carrying a full cup of coffee from the kitchen to the dining room can be precarious for a sleepy-eyed caffeine addict who might accidentally send a wave of java sloshing over the rim. But add a bit of foam to the top and the trip becomes easier. Scientists have found that just a few layers of bubbles can significantly dampen the sloshing motion of liquid.
A chemical found in garlic can kill bacteria that cause life-threatening lung infections in people with cystic fibrosis, research suggests. The study is the first to show that the chemical, known as allicin, could be an effective treatment against a group of infectious bacteria that is highly resistant to most antibiotics.
Scientists have created a high-energy mid-infrared laser powerful enough to create shining filaments in the air. Such devices could be used to detect chemical substances in the atmosphere.
At least five mass extinction events have profoundly changed the history of life on Earth. But a new study led by researchers at the Univ. of Gothenburg shows that plants have been very resilient to those events. For over 400 million years, plants have played an essential role in almost all terrestrial environments and covered most of the world's surface.
A spark from a lightning bolt, interstellar dust or a subsea volcano could have triggered the very first life on Earth. But what happened next? Life can exist without oxygen; but without plentiful nitrogen to build genes, life on the early Earth would have been scarce. The ability to use atmospheric nitrogen to support more widespread life was thought to have appeared roughly 2 billion years ago.
Rivers and streams could be a major source of antibiotic resistance in the environment. The discovery comes following a study on the Thames river by scientists at the Univ. of Warwick and the Univ. of Exeter. The study found that greater numbers of resistant bacteria exist close to some waste water treatment works, and that these plants are likely to be responsible for at least half of the increase observed.
“Antiaromatic compounds” is what chemists call a class of ring molecules which are extremely instable. Because they exist for mere split seconds, they can only be detected by extremely demanding, ultra-fast methods. Researchers from the Cluster of Excellence RESOLV at Ruhr-Univ. Bochum have succeeded in isolating the antiaromatic fluorenyl cation at extremely low temperatures in water ice.
How do you make nickel look and behave like copper? A team of scientists at Yale Univ. has done just that by developing a novel technique to artificially alter a material’s atomic properties by substantially modifying the orbital properties of electrons. The electrons can also be tunably configured in orbital patterns with unique magnetic, superconductive and optical properties.
Mice genetically deficient in serotonin, a crucial brain chemical implicated in clinical depression, are more vulnerable than their normal littermates to social stressors, according to a Duke Univ. study. Following exposure to stress, the serotonin-deficient mice also did not respond to a standard antidepressant, fluoxetine (Prozac), which works by boosting serotonin transmission between neighboring neurons.
Brigham Young Univ. biologist Jonathan Alder has a startling secret he doesn’t freely share: he knows when most of us are going to die. Okay, he doesn’t know exactly the day or time, but he has a pretty good idea, thanks to his research on tiny biological clocks attached to our chromosomes. These DNA end caps, called telomeres, are the great predictors of life expectancy: the shorter your telomeres, the shorter your lifespan.
Planetary scientists have calculated that there are hundreds of billions of Earth-like planets in our galaxy which might support life. The new research, led by The Australian National Univ., made the finding by applying a 200 year old idea to the thousands of exoplanets discovered by the Kepler space telescope.
Firing off a string of action snapshots like a sports photographer at a NASCAR race, NASA's Hubble Space Telescope captured the rare occurrence of three of Jupiter's largest moons racing across the banded face of the gas-giant planet: Europa, Callisto and Io.
Nearly all studies used to promote biofuels as climate-friendly alternatives to petroleum fuels are flawed and need to be redone, according to a Univ. of Michigan researcher. Once the erroneous methodology is corrected, the results will likely show that policies used to promote biofuels actually make matters worse when it comes to limiting net emissions of climate-warming carbon dioxide gas.
A team of scientists has identified the complex process by which materials are shaped and ultimately dissolved by surrounding water currents. The study, conducted by researchers at New York Univ. (NYU)’s Courant Institute of Mathematical Sciences and Florida State Univ., appears in the Journal of Fluid Mechanics.
The more scientists study pigeons, the more they learn how their brains operate in ways not so different from our own. In a new study from the Univ. of Iowa, researchers found that pigeons can categorize and name both natural and manmade objects. These birds categorized 128 photographs into 16 categories, and they did so simultaneously.
While the mysterious, unseen forces magnets project are now (mostly) well understood, they can still occasionally surprise us. For instance, thin films of cobalt have been observed to spontaneously switch their poles: something that typically doesn’t happen in the absence of an external magnetic field. Physicists at NIST and the Univ. of Maryland have measured this phenomenon on the largest scale yet.
Birds are unwitting masters of fluid dynamics: They manipulate airflow each time they flap their wings, pushing air in one direction and moving themselves in another. Two New York Univ. researchers have taken inspiration from avian locomotion strategies and created a pump that moves fluid using vibration instead of a rotor.
Researchers at Virginia Commonwealth Univ. and universities in China and Japan have discovered a new structural variant of carbon called "penta-graphene", a very thin sheet of pure carbon that has a unique structure inspired by a pentagonal pattern of tiles found paving the streets of Cairo.
From manufacturing life-saving biopharmaceuticals to producing energy-efficient biofuels, the cost-effective production of proteins will be essential to revolutionizing the future of health care and energy. For years, scientists have turned to yeast as a quick and inexpensive way to mass-produce proteins for a variety of useful products. Now Northwestern Univ. has found a way to gather more protein without making the yeast produce more.
As a grape slowly dries and shrivels, its surface creases, ultimately taking on the wrinkled form of a raisin. Similar patterns can be found on the surfaces of other dried materials, as well as in human fingerprints. While these patterns have long been observed in nature, and more recently in experiments, scientists have not been able to come up with a way to predict how such patterns arise in curved systems, such as microlenses.
Moderate consumption of alcohol has been associated with health benefits in some, but not all, studies. Researchers at the Yale Univ. School of Medicine may have found an explanation, in part, for why non-smokers might benefit from a glass of wine.
