Follow the pollen. Records from past plant life tell the real story of global temperatures, according to research from a climate scientist at Washington University in St. Louis.

The ability to visually represent artifacts, whether inorganics like stone, ceramic and metal, or organics such as bone and plant material, has always been of great importance to the field of anthropology and archaeology. For researchers, educators, students and the public, the ability to see the past, not only read about it, offers invaluable insights into the production of cultural materials and the populations who made and used them.

Scientists want to increase their understanding of circadian rhythms, those internal 24-hour biological clock cycles of sleeping and waking that occur in organisms, ranging from humans to plants to fungi to bacteria. A research team has examined the complex workings of cyanobacteria and can now better comprehend what drives its circadian clock.

The number of people leaving California for other states appears to have slowed during the last quarter of 2021, while the number of people moving into the state appears to be rebounding, according to new estimates released today by the nonpartisan California Policy Lab (CPL) using credit-bureau data through the end of 2021. These trends are especially pronounced in the Bay Area counties that originally saw the largest pandemic-era shifts in domestic migration, like San Francisco. CPL also released... Читать дальше...

In support of the Biden-Harris Administration's efforts to advance racial equity in the federal government, NASA has released its first-ever Equity Action Plan. The plan establishes key focus areas that will allow the agency to track progress toward improved diversity, equity, inclusion, and accessibility both internally and externally to NASA.

A celestial event mentioned in an ancient Chinese text turns out to be the oldest known reference to a candidate aurora, predating the next oldest one by some three centuries, according to a recent study by Marinus Anthony van der Sluijs, an independent researcher based in Canada, and Hisashi Hayakawa from Nagoya University. This finding was recently published in the journal Advances in Space Research.

A study led by Prof. Qiuyu Zhang (Northwestern Polytechnical University), Prof. Ki-Bum Lee (Rutgers University), and Prof. Liang Kong (School of Stomatology, The Fourth Military Medical University) has established an injectable hybrid inorganic (IHI) nanoscaffold-templated stem cell assembly and applied it to the regeneration of critically-sized cartilage defects.

Hainan has a unique tropical environment with abundant biodiversity and is home to over 400 species of birds. The island in southern China has experienced fast economic development changes over the past 20 years, and although efforts have been taken to protect Hainan's biodiversity, the full impact of the changes is not clear.

A University of Illinois at Urbana-Champaign research team has discovered a way to produce a special class of molecule that could open the door for new drugs to treat currently untreatable diseases.

Each year, humans across the globe produce billions of tons of solid waste. Roughly 70% of this refuse ends up deposited in landfills, where it slowly decays. Yet, what may seem an inert accumulation of useless debris, is in reality, a complex ecosystem, teeming with microbial activity. Vast communities of microorganisms feed on the waste, converting it into byproducts—primarily carbon dioxide (CO2) and methane.

As cities grow, the area of impervious surfaces they cover grows. In cities across the US, roads, rooftops, parking lots, sidewalks and driveways increased by an average of 326,000 hectares per year between 2012 and 2017.

Highly pathogenic avian influenza was confirmed in three bald eagles in Georgia Thursday. This is the first time the virus has been confirmed in the species in the state.

Assistant professor Michael Maseda was one of many who contributed to development of the James Webb Space Telescope.

Nearly all of Earth's organisms communicate with each other in one way or another, from the nods and dances and squeaks and bellows of animals, through to the invisible chemical signals emitted by plant leaves and roots. But what about fungi? Are mushrooms as inanimate as they seem—or is something more exciting going on beneath the surface?

Europe's Spaceport in French Guiana is preparing for the arrival of Ariane 6, ESA's new heavy-lift rocket. The latest round of testing aims to validate the system of fuel lines and mechanical supporting arms that will keep Ariane 6 topped up with liquid hydrogen and liquid oxygen in the critical moments before liftoff. This work is part of the final preparations of the new Ariane 6 launch complex and all the systems necessary for a launch.

A satisfying, audible "pop" marked a successful piercing of the sealed Apollo 17 sample container using the ESA designed and built piercing tool. The tool forms part of a gas sampling system with a gas extraction manifold, designed and built by Washington University St Louis, U.S..

A special form of light made using an ancient Namibian gemstone could be the key to new light-based quantum computers, which could solve long-held scientific mysteries, according to new research led by the University of St Andrews.

The Australian Nuclear Science and Technology Organisation's National Deuteration Facility has provided deuterated cholesterol for international research to gain a better understanding of how the Spike protein of the COVID virus, SARS-Co-V-2, infects human cells through a membrane fusion mechanism.

Now that spring is in the air, the U.K. is starting to see its summer visitors arriving. Ospreys are already back in their nests, chiffchaffs are singing their song to re-establish their territories, and puffins have arrived at their breeding sites around the British Isles.

Recently, PhD student Li Fuxing, Prof. Qian Shengbang and their colleagues from Yunnan Observatories of the Chinese Academy of Sciences discovered 12 semidetached mass-transfer massive binaries from a total of 437 eclipsing binaries in Andromeda galaxy (M31). The secondary (less massive) components filled their Roche lobes, while the more massive ones were detached from the lobes.

New, highly detailed and rigorous maps of bird biodiversity could help protect rare or threatened species.

Even many successful people harbor what is commonly called impostor syndrome, a sense of being secretly unworthy and not as capable as others think. First posited by psychologists in 1978, it is often assumed to be a debilitating problem.

In a busy start to April 2022 for the British chancellor, Rishi Sunak announced his intention to make the U.K. a "global hub for cryptoassets technology." Put simply, this means he wants the country to be an attractive place for cryptocurrency companies to operate.

In the waning days of 2021, a grass fire broke out in Boulder County, Colorado. Fueled by extreme drought and high winds, the fire swept through the communities of Superior and Louisville. Within hours, it had destroyed more than a thousand structures—making the Marshall fire the most destructive in the state's history.

For the first time, researchers have visually monitored, in high resolution, the timing and location of fat storage within the intact cells of fruit flies. The new optical imaging tool from the lab of bioengineering professor Lingyan Shi at the University of California San Diego is already being used to untangle often discussed, yet mysterious, links between diet and things like obesity, diabetes and aging. The work from bioengineers at the UC San Diego Jacobs School of Engineering is published in the journal Aging Cell.
