New evidence our neighborhood in space is stuffed with hydrogen
Only the two Voyager spacecraft have ever been there, and it took than more than 30 years of supersonic travel. It lies well past the orbit of Pluto, through the rocky Kuiper belt, and on for four times that distance. This realm, marked only by an invisible magnetic boundary, is where Sun-dominated space ends: the closest reaches of interstellar space.
Philippines evacuates nearly 1 million as Typhoon Goni nears
Nearly a million people in the Philippines were evacuated from their homes Saturday as the most powerful typhoon of the year so far barrelled towards the country, with authorities warning of "destructive" winds and flooding.
Sri Lanka returns illegal waste to Britain after court order
Sri Lanka has started shipping 242 containers of hazardous waste, including body parts from mortuaries, back to Britain after a two year court battle by an environment watchdog, officials said Saturday.
Experts see substantial danger to democratic stability around 2020 election
On the eve of the November 3 election, Bright Line Watch—the political science research project of faculty at the University of Rochester, the University of Chicago, and Dartmouth College—finds that experts are concerned about substantial risks to the legitimacy of the election, including potential problems in the casting and counting of votes, the Electoral College, and in the resolution of...

Quake strikes Turkish coast and Greek island, killing 14
A strong earthquake struck Friday in the Aegean Sea between the Turkish coast and the Greek island of Samos, killing at least 14 people and injuring over 500 amid collapsed buildings and flooding, officials said.
Asteroid's scars tell stories of its past
By studying impact marks on the surface of asteroid Bennu—the target of NASA's OSIRIS-REx mission—a team of researchers led by the University of Arizona has uncovered the asteroid's past and revealed that despite forming hundreds of millions of years ago, Bennu wandered into Earth's neighborhood only very recently.
China's most important trees are hiding in plain sight
In ecosystems around the globe, the danger of being a common or widespread species is the tendency to be overlooked by conservation efforts that prioritize rarity.
First Australian night bees recorded foraging in darkness
Australian bees are known for pollinating plants on beautiful sunny days, but a new study has identified two species that have adapted their vision for night-time conditions for the first time.
New study reveals United States a top source of plastic pollution in coastal environments
A study published today in the journal Science Advances has revealed that the United States ranks as high as third among countries contributing to coastal plastic pollution when taking into account its scrap plastic exports as well as the latest figures on illegal dumping and littering in the country. The new research challenges the once-held assumption that the United States is adequately...
To survive asteroid impact, algae learned to hunt
Tiny, seemingly harmless ocean plants survived the darkness of the asteroid strike that killed the dinosaurs by learning a ghoulish behavior—eating other living creatures.
New drone technology improves ability to forecast volcanic eruptions
Specially-adapted drones developed by a UCL-led international team have been gathering data from never-before-explored volcanoes that will enable local communities to better forecast future eruptions.
A new spin on atoms gives scientists a closer look at quantum weirdness
When atoms get extremely close, they develop intriguing interactions that could be harnessed to create new generations of computing and other technologies. These interactions in the realm of quantum physics have proven difficult to study experimentally due the basic limitations of optical microscopes.
Pebble Mine developer promised riches, but expects $1.5 billion subsidy from Alaskans
The company seeking to develop Pebble Mine in the headwaters of Bristol Bay has long promised that the controversial project would bring Alaska jobs, economic growth and tax revenue.
COVID-19 a 'golden opportunity' for terror organisations to intensify their propaganda
The uncertainty and confusion caused by the COVID-19 pandemic is being "widely exploited by terror groups for spinning a plethora of sinister schemes", which could lead to a new tide of violence against people and governments.
Future lake food webs in subarctic have more biomass and contain more omega-3 fatty acids
Subarctic regions are facing rapid changes in climate and land-use intensity. An international research team recently completed an investigation to see how these changes are affecting the food webs and fish communities of lakes in northern Finland. Biomasses and omega-3 fatty acids, EPA and DHA, were determined from the algal producers at the base of food web to large carnivorous fish from 20...
Dynamic photonic barcodes record energy transfer at the biointerface
Optical barcodes enable detection and tracking via unique spectral fingerprints. They've been widely applied in areas ranging from multiplexed bioassays and cell tagging to anticounterfeiting and security. Yu-Cheng Chen of the Bio+Intelligent Photonics Laboratory at Nanyang Technological University notes that the concept of optical barcodes typically refers to a fixed spectral pattern...
In a hurry to develop drugs? Here's your cHAT
Let's call it the Texas two-step, but for molecules.
How the waters off Catalina became a DDT dumping ground
Not far from Santa Catalina Island, in an ocean shared by divers and fishermen, kelp forests and whales, David Valentine decoded unusual signals underwater that gave him chills.
Assessing the habitability of planets around old red dwarfs
A new study using data from NASA's Chandra X-ray Observatory and Hubble Space Telescope gives new insight into an important question: how habitable are planets that orbit the most common type of stars in the Galaxy? The target of the new study, as reported in our press release, is Barnard's Star, which is one of the closest stars to Earth at a distance of just 6 light years. Barnard's Star is a...
A Subterranean ecosystem in the Chicxulub crater
A new study reveals that the Chicxulub impact crater and its hydrothermal system hosted a subterranean ecosystem that could provide a glimpse of Earth's primordial life.
Scary insects for Halloween: the bloodthirsty calyptra
Sometimes insects show signs of monster behavior.
The scariest things in the universe are black holes—and here are three reasons
Halloween is a time to be haunted by ghosts, goblins and ghouls, but nothing in the universe is scarier than a black hole.
Copernicus captures image of the Republic of Maldives
All 1200 islands that make up the Republic of Maldives are featured in this spectacular image captured by the Copernicus Sentinel-3 mission.
Copernicus Sentinel-6 measuring sea-levels using radar altimetry
This November the newest member of the EU's Copernicus program, Sentinel-6 Michael Freilich, will take to the heavens from Vandenberg Air Force Base in California. The satellite is named after NASA's former Director of Earth Observation and is a radar altimetry mission to monitor sea-level rise, wave-height and windspeed.
The traits of Florisbad skull reinforce the mosaic hypothesis of human evolution
Emiliano Bruner, a paleoneurologist at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), in collaboration with Marlize Lombard, of the University of Johannesburg, has just published a study in the Journal of Anthropological Sciences which describes the braincase traits of Florisbad, a fossil found in South Africa in 1932, and its similarities with other species like Homo...
