Faster electronic device architectures are in the offing with the unveiling of the world’s first fully two-dimensional field-effect transistor (FET) by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab). Unlike conventional FETs made from silicon, these 2D FETs suffer no performance drop-off under high voltages and provide high electron mobility, even when scaled to a monolayer in thickness.
Astronomers studying two classes of black-hole-powered galaxies monitored by NASA's Fermi Gamma-ray Space Telescope have found evidence that they represent different sides of the same cosmic coin. By unraveling how these objects, called blazars, are distributed throughout the universe, the scientists suggest that apparently distinctive properties defining each class more...
Bigger smartphone screen size may be better for more than just practical reasons, according to researchers. Participants in a study on smartphones indicated that emotional reasons might influence their decision to buy smartphones with bigger screens even more than practical ones,
Researchers at Washington State University have used a super-cold cloud of atoms that behaves like a single atom to see a phenomenon predicted 60 years ago and witnessed only once since. The phenomenon takes place in the seemingly otherworldly realm of quantum physics and opens a new experimental path to potentially powerful quantum computing.
Computer scientists at Microsoft Research and the University of California, San Diego have developed a system that combines a mobile application and sensor to detect stress in parents and delivers research-based strategies to help decrease that stress during emotionally charged interactions with their children. The system was initially tested on a small group of parents of children with ADHD.
A German museum has put on display a copy of Vincent van Gogh's ear that was grown using genetic material provided by one of the 19th-century Dutch artist's living relatives. The Center for Art and Media in Karlsruhe said artist Diemut Strebe made the replica using living cells from Lieuwe van Gogh, the great-great-grandson of Vincent's brother Theo.
NEW YORK (AP) — A Virginia fossils dealer was sentenced Tuesday to three months in prison even after a prosecutor described his cooperation with law enforcement in heroic terms, saying he enabled more than 18 largely complete dinosaur fossils to be located, enough for Mongolia to open its first dinosaur museum.
Astronomers using the Hubble Space Telescope have captured the most comprehensive picture ever assembled of the evolving Universe – and one of the most colourful. The study is called the Ultraviolet Coverage of the Hubble Ultra Deep Field (UVUDF) project.
The photo sharing app Instagram is adding editing tools that go beyond the vintage-looking filters that made it popular. The Facebook-owned app said in a blog post Tuesday that users will be able to adjust the brightness, contrast, saturation and other features of photos they take with their smartphones.
In an attempt to curry favor with regulators, AT&T Inc. said Tuesday that if it's allowed to buy satellite broadcaster DirecTV, it will be able to afford an expansion of fiber connections into more homes to boost their Internet connection speeds.
A federal judge has dismissed a lawsuit an Idaho woman filed against President Barack Obama and other federal officials over the National Security Agency's collection of cellphone information. U.S. District Judge Lynn Winmill ruled Tuesday that under current U.S. Supreme Court precedents, the NSA's collection of cellphone data doesn't violate the Fourth Amendment's prohibition of unreasonable searches.
The volume of email cloaked in encryption technology is rapidly rising as Google, Yahoo, Facebook and other major Internet companies try to shield their users' online communications from government spies and other snoops. Google and other companies are now automatically encrypting all email, but that doesn't ensure confidentiality unless the recipients' email provider also adopts the technology.
The number of nerve cells in the human brain sounds impressive: 100 billion. And it is. But neurons may make up as little as 15 percent of cells in the brain. The other cells are called glial cells, or glia. Glia are the rising stars of the neuroscience universe. Once delegated to simply a...
Solar Impulse 2, a.k.a. the "Round-the-World" solar airplane, is a single-seater airplane made from carbon fiber with 17,000 solar cells that supple four electric 17.5 CV (each) with energy. Those solar cells recharge the lithium batteries that allow the plane to fly at night.
Not everyone gets to meet the President of the United States. For Hudson High (right blue shirt), a Texas A&M graduate with a degree in industrial engineering, the opportunity was exhilarating and exhausting. He went to work at his job at the Ford Plant in Kansas City like he did every day....
