Hundreds of firefighters, water-bombing planes and helicopters battled forest fires near Athens on Tuesday that saw villages evacuated and part of a major motorway closed, officials said.

A single molecule contains a wealth of information. It includes not only the number of each kind of constituent atom, but also how they're arranged and how they attach to each other. And during chemical reactions, that information determines the outcome and becomes transformed. Molecules collide, break apart, reassemble, and rebuild in predictable ways.

When the Human Genome Project reached its ambitious goal of mapping the entire human genome, it seemed the world was entering an era of personalized medicine, where evidence from our own specific genetic material would guide our care.

For more than 25 years, the Advanced Photon Source's intense X-rays have enabled important breakthroughs. With a massive upgrade in the works, scientists will be able to see things at scale never seen before.

For over a decade, researchers have known that the roundworm Caenorhabditis elegans can detect and avoid short-wavelength light, despite lacking eyes and the light-absorbing molecules required for sight. As a graduate student in the Horvitz lab, Nikhil Bhatla proposed an explanation for this ability. He observed that light exposure not only made the worms wriggle away, but it also prompted them to stop eating. This clue led him to a series of studies that suggested that his squirming subjects weren't... Читать дальше...

Millions of army ants occasionally stream out of their nest in a coordinated hunting swarm, seeking prey to devour. How this extraordinary mass raiding behavior evolved has long been a mystery, until now.

Roaring blazes encircled a Turkish thermal power plant Tuesday and forced farmers to herd panicked cattle toward the sea as wildfires that have killed eight people raged on for a seventh day.

Researchers from The Pennsylvania State University and the University of South Carolina published a new paper in the Journal of Marketing that examines a digital marketing campaign's impact on improving low consumer recall completion rates.

A new study published today in Global Change Biology provides valuable new data that highlights how species extinction risk is accelerating due to rapid climate change and an increase in extreme climate events, such as glacial calving and sea ice loss. The study, led by Stephanie Jenouvrier, associate scientist, and seabird ecologist at Woods Hole Oceanographic Institution, and co-authored by an international team of scientists, policy experts, ecologists, and climate scientists, provided pivotal...

A different kind of design for absorbing vibrations could help better soundproof walls and make vehicles more streamlined, a new study shows.

The study of the orogenic effects of the Tibetan Plateau uplift on global climate during the Cenozoic has focused almost exclusively on the India-Asia collision zone, the Himalayas. The strong erosion in the Himalayas was assumed to be a primary driver of Cenozoic atmospheric CO2 decline and global cooling predominantly through accelerating silicate chemical weathering in the India-Asia collision zone or through effective burial of organic carbon in the nearby Bengal Fan in South Asia.

Millimeter wave (mmWave) communications have attracted extensive interest from academia, industry, and government as they can make full use of abundant frequency resources at the high-frequency band to achieve ultra-high-speed data transmission. The mmWave communication systems are usually equipped with large antenna arrays, known as mmWave massive multiple-input multiple-output (MIMO), to generate highly directional beams and compensate for the severe path loss in the high frequency band. However... Читать дальше...

Boeing said Tuesday it was delaying an uncrewed flight of its Starliner capsule to the International Space Station (ISS), pushing back a key test it last attempted in 2019.

Users banned from social platforms go elsewhere with increased toxicity, according to a new study featuring researchers from Binghamton University, State University of New York.

Bent concrete beams, cracks on the undersides of bridges, risk of rust for the reinforcement: In Switzerland, many structures are getting on in years. Take national roads, for example: According to the 2019 report of the Federal Roads Office (FEDRO), a large proportion of bridges were built between the mid-1960s to the 1980s—with significantly lower traffic loads than today.

Illustrations depicting the dinosaur era—whether in books or movies—are often accompanied by lush greenery. During the Cretaceous period, the trees commonly dominating a wide range of Earth's terrestrial environments were conifers—similar to the pines, spruces, cypresses and cedars that populate the earth today. These conifers played a key role in ecosystems, providing nourishment, nutrients, and habitat for a range of prehistoric creatures.

Water authorities will be turning to Melburnians to help with a novel system of 'smart' rainwater tanks and urban lakes that can provide crucial water to support platypus habitat when it's most needed—just before the breeding season.

When putting a house on the market, who has the edge when it comes to selling for a profit?

Ovarian cancer devastates more than 20,000 women in the U.S. every year, due in part to its tendency to evade detection and present after metastatic spread. A key element to slowing metastasis is understanding the mechanisms of how tumor cells invade tissues.

In efforts to fight obesity and enhance drug absorption, scientists have extensively studied how gastric juices in the stomach break down ingested food and other substances. However, less is known about how the complex flow patterns and mechanical stresses produced in the stomach contribute to digestion.

Proteins—long chains of amino acids—each play a unique role in keeping our cells and bodies functioning, from carrying out chemical reactions, to delivering messages, and protecting us from potentially harmful foreign invaders. More recent research has shown that these proteins not only serve their individual purpose, but also interact with other proteins to carry out even more numerous and complex functions through these protein-protein interactions (PPI).

In 1842, Charles Darwin described the Belize Barrier Reef as "the most remarkable reef in the West Indies." Fast forward to 2021, only about 17 percent of live coral cover remains on fore-reefs in Belize. Overfishing, resulting in reduced grazing of algae, has long been blamed for adversely impacting this globally significant ecosystem along the Caribbean coast of Central America. Designated in part as a UNESCO World Heritage Site in 1996, the Mesoamerican reef is second in length only to the iconic Great Barrier Reef in Australia.

A team of researchers from the University of Hong Kong and one from Oxford University has found that people who live in the denser parts of U.K. cities tend to be lonelier than people living in more open areas. In their paper published in the journal Landscape and Urban Planning, the group describes their study of health data for people in the U.K. and what they found.

In a finding that will give theorists plenty to ponder, an all-RIKEN team has observed an unexpected response in an exotic material known as a Mott insulator when they injected electrons into it. This observation promises to give physicists new insights into such materials, which are closely related to high-temperature superconductors.

In the latest of ongoing efforts to expand technologies for modifying genes and their expression, researchers in the lab of Neville Sanjana at New York University (NYU) and the New York Genome Center (NYGC) have developed chemically modified guide RNAs for a CRISPR system that targets RNA instead of DNA. These chemically modified guide RNAs significantly enhance the ability to target—trace, edit, and/or knockdown—RNA in human cells.
