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 […]

- A coal-export terminal proposed in Washington state would increase cancer risks for some residents, make rail accidents more likely and add millions of metric tons of climate-changing greenhouse gas globally every year, according to an environmental study released Friday.
- A second petroleum company said it would shut down and inspect wells after a fatal house explosion near a gas well in Colorado, although investigators have not said whether the well was the cause.
- It's the time of year to reward graduates, many of whom will hit the real world. Here are some tech gift suggestions of useful gadgets for everyday life and even to have a good night's sleep.
- "We mortals do not understand you." That's the heartfelt cry from former UN climate chief Christiana Figueres, pleading with scientists to use everyday language to help counter growing public mistrust.
- A powerful earthquake with a magnitude of 7.2 struck off a southern Philippine province Saturday and prompted a local tsunami warning, but there were no immediate reports of damage or injuries.
- Cooling off: Analysis shows declining engagement with Trump's tweets
- A hacker claims to have stolen the upcoming season of Netflix's hit series "Orange Is The New Black," and is asking for an unspecified ransom to not release the entire fifth season online.
- The National Security Agency announced Friday it would end its controversial practice of sweeping up any email or text message an American exchanges with someone overseas that makes reference to a real target of NSA surveillance.
- SpaceX on Sunday is scheduled to make its first military launch, with a classified payload for the National Reconnaissance Office, which makes and operates spy satellites for the United States.
- Two NASA satellites provided forecasters in Australia with visible and rainfall data as Tropical Cyclone Frances strengthened in the western Timor Sea. NASA's Aqua satellite captured a visible image of the storm that showed a cloud-filled eye, while the Global Precipitation Measurement Mission or GPM core satellite found heaving rainfall occurring.
- The United States is considering a $1 trillion budget proposal to update infrastructure, including its crumbling bridges. An obstacle to spending the money wisely is that the current means of assessing bridges may underestimate their vulnerability, according to a new study published in the Journal of Infrastructure Systems.
Study finds bonobos may be better representation of the last common ancestor with humans than common chimpanzeesA new study examining the muscular system of bonobos provides firsthand evidence that the rare great ape species may be more closely linked, anatomically, to human ancestors than common chimpanzees. Previous research suggested this theory at the molecular level, but this is the first study to compare in detail the anatomy of the three species.
- NASA has selected an instrument developed by Mark Robinson of ASU's School of Earth and Space Exploration (SESE) and Malin Space Science Systems (MSSS) to map the terrain and search for evidence of frost or ice deposits in the Moon's permanently shadowed regions (PSRs).
- New, creative but more high-tech methods may finally be turning the tide in the fight against invasive species
- Tropical rainforests are often described as the "lungs of the earth," able to inhale carbon dioxide from the atmosphere and exhale oxygen in return. The faster they grow, the more they mitigate climate change by absorbing CO2.
With unique data, researchers track the effect of Brazil's 'Soy Moratorium' on an advancing agricultural frontierThe Brazilian state of Mato Grosso produces enough soybeans to be the equivalent of Iowa and Illinois put together. But it also plays home to lush Amazon rain forest, one of the richest, and most vulnerable, ecological treasures on our planet.
- New research from North Carolina State University has found that combining digital and analog components in nonlinear, chaos-based integrated circuits can improve their computational power by enabling processing of a larger number of inputs. This "best of both worlds" approach could lead to circuits that can perform more computations without increasing their physical size.
- Researchers at the Georgia Institute of Technology and Peking University have found a new use for the ubiquitous PowerPoint slide: Producing self-folding three-dimensional origami structures from photocurable liquid polymers.
- New research could make lasers emitting a wide range of colors more accessible and open new applications from communications and sensing to displays.
- Hydrogen (H2) has attracted considerable attention as a clean energy source because the only by-product of its reaction with oxygen is water, and high efficiency for energy conversion is achieved when it is combined with fuel cell technologies.
- US President Donald Trump signed an executive order aimed at lifting bans on drilling for oil and gas in offshore Arctic and Atlantic areas, saying it would pull in "billions of dollars" for America and create jobs.
- Yersinia pestis, the bacterium that causes bubonic plague, can survive within the ubiquitous soil protozoan, the amoeba, by producing proteins that protect against the latter microbe's digestion. The research is published April 28th in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

- Astronomers have used data from NASA's Chandra X-ray Observatory to study the properties of dark matter, the mysterious, invisible substance that makes up a majority of matter in the universe. The study, which involves 13 galaxy clusters, explores the possibility that dark matter may be more "fuzzy" than "cold," perhaps even adding to the complexity surrounding this cosmic conundrum.
- Leiden physicists exploit self-assembly of small particles to someday create functional structures such as micro-robots from the bottom up. Now they took an important step forward by experimentally realizing joints on the micrometer scale. The study is published in Nanoscale journal.
