Incarceration in the United States is frequently described as an epidemic, with per capita rates nearly quadrupling in the past 30 years. African-Americans appear to be particularly susceptible: In 2011, they were six times more likely than whites to be incarcerated, making up 38% of the 1.6 million Americans behind bars while accounting for only 13% of the U.S. population. Now, a computer simulation originally developed to track infectious disease suggests the longer prison sentences that blacks often receive may accelerate the rate of “infection.”
In the past years, invisibility cloaks were developed for various senses. Objects can be hidden from light, heat or sound. However, hiding of an object from being touched still remained to be accomplished. KIT scientists have now succeeded in creating a volume in which an object can be hidden from touching similar to a pea under the mattress of a princess. The results are now presented in the renowned Nature Communications journal.
Physicists have found more evidence that the "Higgs-like particle" they discovered two years ago behaves just as the fabled Higgs boson should — and they've begun ramping up for fresh discoveries from the Large Hadron Collider, the world's biggest particle-smasher.
Dark matter is one of the universe's most befuddling, and elusive, components. It could make up roughly a quarter of the universe's total mass and energy, yet no one knows for sure because no one has actually seen it. Well, it may be showing itself at last. nasa's Fermi Gamma-ray Space Telescope has recorded high-energy gamma-ray light emanating from the center of the Milky Way that fits well with dark matter predictions.
A distant galaxy containing three supermassive black holes, each millions to billions of times more massive than the Sun, has been discovered 4 billion light-years away.
Space may appear empty -- a soundless vacuum, but it's not an absolute void. It flows with electric activity that is not visible to our eyes. NASA is developing plans to send humans to an asteroid, and wants to know more about the electrical environment explorers will encounter there.
Surrounding the sun is a vast atmosphere of solar particles, through which magnetic fields swarm, solar flares erupt, and gigantic columns of material rise, fall and jostle each other around. Now, using NASA's Solar Terrestrial Relations Observatory, scientists have found that this atmosphere, called the corona, is even larger than thought.
A star in a neighboring galaxy might have swallowed another star. Sitting about 200,000 light-years away in the constellation Tucana, the star HV 2112 appears to be a red supergiant that has engulfed a neutron star. This strange pair, called a Thorne-Zytkow Object, or TZO, was largely theoretical until now.
A newfound alien world might be able to support life — and it's just a stone's throw from Earth in the cosmic scheme of things.
With its solar panels their cleanest in years, NASA's decade-old Mars Exploration Rover Opportunity is inspecting a section of crater-rim ridgeline chosen as a priority target due to evidence of a water-related mineral.
3,500 million years ago the Martian crater Gale, through which the NASA rover Curiosity is currently traversing, was covered with glaciers, mainly over its central mound. Very cold liquid water also flowed through its rivers and lakes on the lower-lying areas, forming landscapes similar to those which can be found in Iceland or Alaska. This is reflected in an analysis of the images taken by the spacecraft orbiting the red planet.
CORVALLIS, Ore. – A new study suggests that a warming period more than 400,000 years ago pushed the Greenland ice sheet past its stability threshold, resulting in a nearly complete deglaciation of southern Greenland and raising global sea levels some 4-6 meters.
Scientists excavating an archaeological site in southern Spain have finally gotten the real poop on Neandertals, finding that the Caveman Diet for these quintessential carnivores included substantial helpings of vegetables. Using the oldest published samples of human fecal matter, archaeologists have found the first direct evidence that Neandertals in Europe cooked and ate plants about 50,000 years ago.
Consuming a plant-based diet results in a more sustainable environment and reduces greenhouse gas emissions, while improving longevity, according to new research. Based on findings that identified food systems as a significant contributor to global warming, the study focuses on the dietary patterns of vegetarians, semi-vegetarians and non-vegetarians to quantify and compare greenhouse gas emissions, as well as assess total mortality.
We all feel lonely from time to time. It is one of the fundamental aspects of human nature for us to desire to share time and space with others of our own kind. When devoid of this contact, we can be pulled down into the dark depths of despair. But can you imagine the extreme loneliness of not only being being truly, soul crushingly alone, but forgotten as well? Can you imagine being the very last of your people?
2014 marks the 45th anniversary of the Skamania County Sasquatch Refuge. The closest thing to official government recognition the creature has ever had.
It’s no secret that wolves, foxes, and dogs are highly social animals. But beyond all the wagging, pawing and yipping we like to try to interpret, canids may have yet another way to communicate. New research hints at the possibility that dogs and their ilk could be sending each other signals with their eyes.
