When Hurricane Irma hit southern Florida in September of 2017, the storm buffeted coastal mangrove forests with winds over 116 mph—strong enough to rip off leaves, break branches, and snap tree trunks in half. Of the mangrove forest damaged by Hurricane Irma, about 83% recovered after the first year. But the rest didn't, leaving scientists wondering why some trees didn't bounce back.

Agglutination assays are widely used immunological sensors based on antigen-antibody interactions that result in clumping of antibody-coated microscopic particles. Once the sample—for example, a patient's serum—is introduced, the corresponding target antigens in the sample rapidly attach to the antibody binding sites and the particles start to form clusters due to the target antigen's capability of binding to different sites simultaneously. The level of clustering among the particles is indicative of the amount of antigen present in a sample. Читать дальше...

To take advantage of the growing abundance and cheaper costs of renewable energy, Lawrence Livermore National Laboratory (LLNL) scientists and engineers are 3D printing flow-through electrodes (FTEs), core components of electrochemical reactors used for converting CO2 and other molecules to useful products.

When we fixate an object, its image does not appear at the place where photoreceptors are packed most densely. Instead, its position is shifted slightly nasally and upwards from the cellular peak. This is shown in a recent study conducted at the University of Bonn (Germany), published in the journal Current Biology. The researchers observed such offsets in both eyes of 20 healthy subjects, and speculate that the underlying fixation behavior improves overall vision.

Carbon is everywhere. It's in the atmosphere, in the oceans, in the soil, in our food, in our bodies. As the backbone of all organic molecules that make up life, carbon is a very accurate predictor of crop yields. And soil is the largest carbon pool on earth, playing an important role in keeping our climate stable.

Researchers from the Neuroimaging Center at NYU Abu Dhabi (NYUAD) and Wisconsin Institute for the Discovery at University Wisconsin-Madison have developed the UW Virtual Brain Project, producing unique, interactive, 3D narrated diagrams to help students learn about the structure and function of perceptual systems in the human brain. A new study exploring how students responded to these lessons on desktop PCs and in virtual reality (VR) offers new insights into the benefits of VR as an educational tool.

A new study by Tel Aviv University reveals significant ecological damage to many MPAs around the world. The study findings point to a strong "edge effect" in MPAs, i.e. a sharp 60% reduction in the fish population living at the edges of the MPA (up to a distance of 1-1.5 km within the MPA) compared to core areas. The "edge effect" significantly diminishes the effective size of the MPA, and largely stems from human pressures, first and foremost overfishing at the borders of the MPA.

Adolescence can be an emotionally turbulent time, but new research at Penn State found that close, supportive relationships with parents—especially dads—at key points during adolescence can help stave off certain adjustment problems.

Chemical catalysts are the change agents behind the production of just about everything we use in our daily lives, from plastics to prescription drugs. When the right catalysts are mixed with the right chemical compounds, molecules that would otherwise take years to interact do so in mere seconds.

Removal of an offender's hand, tongue or ear: punishments described in Babylon's Hammurabi Code, depended on the nature of the crime. Published in 1771 B.C., the code set the first formal standards for business interactions. But scientists disagree about whether punishment is necessary to maintain mutually-beneficial interactions between animals and plants in nature. In a new study in Proceedings of the National Academy of Sciences, researchers at the Smithsonian Tropical Research Institute (STRI)... Читать дальше...

A team of researchers headquartered at the University of Massachusetts Amherst has recently discovered that fear plays an important, unrecognized role in the underdevelopment, and increased vulnerability, of backyard songbirds.

The pandemic has turned many of us to technology as a way to connect with not just other people, but also nature.

The shadows cast by the roughness of the Moon's surface create small cold spots for water ice to accumulate even during the harsh lunar daytime.

More than two weeks after a flood of raw sewage inundated the Hyperion Water Reclamation Plant and triggered a massive discharge into Santa Monica Bay, the damaged facility has continued to release millions of gallons of partially treated wastewater into the Pacific Ocean, in violation of its environmental permit, the Los Angeles Times has learned.

Nearly a month into bloom season, a harmful algal bloom has been detected along Lake Erie's shores by the National Centers for Coastal Ocean Science.

A few months before the COP26 global climate conference in Glasgow, Scotland, the United Nations climate chief has called on the international community to make more ambitious plans to reduce greenhouse gas emission.

Researchers working with Oak Ridge National Laboratory developed a new method to observe how proteins, at the single-molecule level, bind with other molecules and more accurately pinpoint certain molecular behavior in complex physiological environments.

Scientists at Oak Ridge National Laboratory added new plant data to a computer model that simulates Arctic ecosystems, enabling it to better predict how vegetation in rapidly warming northern environments may respond to climate change.

Oak Ridge National Laboratory researchers have developed a new catalyst for converting ethanol into C3+ olefins—the chemical building blocks for renewable jet fuel and diesel—that pushes the amount produced to a record-high 88%, a more than 10% gain over their previously developed catalyst.

A research team at Oak Ridge National Laboratory have 3D printed a thermal protection shield, or TPS, for a capsule that will launch with the Cygnus cargo spacecraft as part of the supply mission to the International Space Station. The launch will mark the first time an additively manufactured TPS has been sent to space.

The adsorption of ions from the electrolyte at an electrode surface is a ubiquitous process, of use for both existing and emerging electrochemical energy technologies. But what happens when these ions penetrate very small spaces? To address this question, researchers at NC State re-examined the behavior of a "classic" material, birnessite.

Two hundred fifty-two million years ago, much of life on planet Earth was dying.

The rise and fall of sea levels influence the likelihood of volcanic eruptions on the Greek island of Santorini, new research led by Oxford Brookes University has discovered. Analyzing the timings of eruptions over hundreds of thousands of years, the researchers found that a 40 meter fall in sea level is a crucial point beyond which eruptions are more likely to occur. The findings could have implications for millions of people living on volcanic islands around the world.

By analyzing the data from various surveys, a British amateur astronomer has found that a recently discovered star, designated WISEA J052305.94-015356.1, may be a representative of a rare class of subdwarfs—an extreme subdwarf of the T spectral class (esdT). The finding is reported in a paper published July 23 on arXiv.org.

Huan Huan, a giant panda on loan to France, gave birth to twin cubs very early Monday, according to the Beauval zoo.
