Researchers from UCLA have developed a terahertz modulator that performs across a wide range of the terahertz band with very high efficiency and signal clarity, which could eventually lead to more advanced medical and security imaging systems. A UCLA Henry Samueli School of Engineering and Applied Science research team has developed a breakthrough broadband modulator […]

- Scientists are getting closer to finding worlds that resemble our own "blue marble" of a planet. NASA's Kepler mission alone has confirmed more than 1,000 planets outside our solar system—a handful of which are a bit bigger than Earth and orbit in the habitable zones of their stars, where liquid water might exist. Some astronomers think the discovery of Earth's true analogs may be around the corner. What are the next steps to search for life on these potentially habitable worlds?
- We humans might not be the only ones to ponder our place in the universe. If intelligent aliens do roam the cosmos, they too might ask a question that has gripped humans for centuries: Are we alone? These aliens might even have giant space telescopes dedicated to studying distant planets and searching for life. Should one of those telescopes capture an image of our blue marble of a planet, evidence of forests and plentiful creatures would jump out as simple chemicals: oxygen, ozone, water and me
- More tigers have been killed in India already this year than in the whole of 2015, a census showed Friday, raising doubts about the country's anti-poaching efforts.
- Chinese search engine giant Baidu is planning to produce driverless cars by 2020, its chief executive said, as the company reported revenue climbed sharply in the first quarter.
- The world's rarest parrot has enjoyed a bumper breeding season in New Zealand, raising hopes it can eventually be reintroduced to its native Fiordland, conservationists said Friday.
- Large parts of Australia's Great Barrier Reef could be dead within 20 years as climate change drives mass coral bleaching, scientists warned Friday.
- Withering drought and sizzling temperatures from El Nino have caused food and water shortages and ravaged farming across Asia, and experts warn of a double-whammy of possible flooding from its sibling, La Nina.
- Japan's space agency has abandoned its efforts to restore the operations of a multimillion-dollar satellite that was to probe the mysteries of black holes using X-ray telescopes.
- Studying the way that solitary hunters such as tigers, bears or sea turtles chase down their prey turns out to be very useful in understanding the interaction between individual white blood cells and colonies of bacteria. Reporting their results in the Journal of Physics A: Mathematical and Theoretical, researchers in Europe have created a numerical model that explores this behaviour in more detail.
- Amazon is clearly entering its Prime. Meaning, of course, its $100 annual membership program, now a decade old, which has accomplished the remarkable feat of convincing millions of people to pay an annual fee for the privilege of, well, shopping.
- Shares in Baidu jumped on Thursday after the company often referred to as China's version of Google reported that revenue climbed as ads flowed into its search engine.
- Two-dimensional phosphane, a material known as phosphorene, has potential application as a material for semiconducting transistors in ever faster and more powerful computers. But there's a hitch. Many of the useful properties of this material, like its ability to conduct electrons, are anisotropic, meaning they vary depending on the orientation of the crystal. Now, a team including researchers at Rensselaer Polytechnic Institute (RPI) has developed a new method to quickly and accurately determin
- Billionaire investor Carl Icahn has sold his stake in Apple, citing concerns about the giant tech company's prospects in China.
- Amazon on Thursday reported a fourth consecutive quarterly profit, sending shares surging for the online giant known better for its customer connections than its profit margins.
Probing dark energy with clusters: "Russian doll" galaxy clusters reveal information about dark energyThese four galaxy clusters were part of a large survey of over 300 clusters used to investigate dark energy, the mysterious energy that is currently driving the accelerating expansion of the Universe, as described in our latest press release. In these composite images, X-rays from NASA's Chandra X-ray Observatory (purple) have been combined with optical light from the Hubble Space Telescope and Sloan Digital Sky Survey (red, green, and blue).
- Nearly 10 billion years ago, the black hole at the center of a galaxy known as PKS B1424-418 produced a powerful outburst. Light from this blast began arriving at Earth in 2012. Now astronomers using data from NASA's Fermi Gamma-ray Space Telescope and other space- and ground-based observatories have shown that a record-breaking neutrino seen around the same time likely was born in the same event.
- Can a cell sense its own shape? Working in the Marine Biological Laboratory's Whitman Center, scientists from Dartmouth College developed an ingenious experiment to ask this question. Their conclusion - Yes - is detailed in a recent paper in the Journal of Cell Biology.
- Amazon's revenue topped analysts' expectations by a wide margin as the Prime loyalty program helped the online retail giant attract more customers.
- Firefighters entering burning buildings, athletes competing in the broiling sun and workers in foundries may eventually be able to carry their own, lightweight cooling units with them, thanks to a nanowire array that cools, according to Penn State materials researchers.
- The discovery of long non-coding RNA (lncRNA) has dramatically changed the understanding of the biology of diseases such as cancer. The human genome contains about 20,000 protein-coding genes - less than 2 percent of the total - but 70 percent of the genome is made into non-gene-encoding RNA.
- South Korean consumer electronics giant Samsung on Thursday wooed app makers as it pursued a vision of being at the heart of life in a hyper-connected world.
- Centuries before modern countries such as Dubai and China started building islands, native peoples in southwest Florida known as the Calusa were piling shells into massive heaps to construct their own water-bound towns.
- Fiat Chrysler and Google's self-driving car project are in advanced talks to form a technical partnership.
- Comcast is buying DreamWorks Animation, the film company behind the "Shrek," ''Madagascar" and "Kung Fu Panda" franchises, for approximately $3.55 billion, strengthening its presence in the important and growing business of children's entertainment.
- Facebook said Thursday it had received 13 percent more government requests for user data in the second half of 2015, with more than 46,000 requests worldwide.
- The EU's top court on Thursday overturned free quotas for the bloc's carbon market up to 2030, a key part of strategies to curb global warming emissions.
- Online commerce colossuseBay on Thursday opened a virtual wine shop.
- Climate change is exposing millions of workers to excessive heat, risking their health and income and threatening to erase more than $2.0 trillion in annual productivity by 2030, a UN report warned Thursday.
- New research suggests that the very oldest pieces of rock on Earth—zircon crystals—are likely to have formed in the craters left by violent asteroid impacts that peppered our nascent planet, rather than via plate tectonics as was previously believed.
