Tonnes of dead fish have washed up on the shore of a highly polluted lake in eastern Lebanon in the past few days, an official said Thursday.

Researchers in the materials department in UC Santa Barbara's College of Engineering have uncovered a major cause of limitations to efficiency in a new generation of solar cells.

An international team led by Xiangming Xiao, George Lynn Cross Research Professor in the Department of Microbiology and Plant Biology, University of Oklahoma College of Arts and Sciences, published a paper in the April issue of the journal Nature Climate Change that has major implications on forest policies, conservation and management practices in the Brazilian Amazon. Xiao also is director of OU's Center for Earth Observation and Modeling. Yuanwei Qin, a research scientist at the Center for Earth Observation and Modeling... Читать дальше...

Cambridge plant scientists say circadian clock genes, which enable plants to measure daily and seasonal rhythms, should be targeted in agriculture and crop breeding for higher yields and more sustainable farming.

Microalgae of the dinoflagellate group are known for their ability to survive in other animal cells. These tiny single-cell organisms have engaged in mutually beneficial relationships with corals since primeval times. By passing on critical nutrients to their hosts, dinoflagellates allow corals to thrive even in barren areas. A research team from the Centre for Organismal Studies (COS) of Heidelberg University recently discovered that such symbioses within the cell essentially depend on the ability... Читать дальше...

Individuals who self-identify as Republicans became more skeptical of a potential COVID-19 vaccine and other inoculations, such as the flu shot, over the course of the pandemic, reveals a new study by the University of California San Diego's Rady School of Management.

When heavy ions, accelerated to the speed of light, collide with each other in the depths of European or American accelerators, quark-gluon plasma is formed for fractions of a second, or even its 'cocktail' seasoned with other particles. According to scientists from the IFJ PAN, experimental data show that there are underestimated actors on the scene: photons. Their collisions lead to the emission of seemingly excess particles, the presence of which could not be explained.

If you stumble upon an unusual rock that could be a meteorite, do not place a magnet on it to see if it's magnetic—you'd end up erasing 4.5 billion years of magnetic history. Meteorites are remnants of our solar system's first protoplanets and, in some cases, retain a record of the magnetic fields they've experienced in the distant past.

Polish researchers examining an ancient Egyptian mummy that they expected to be a male priest were surprised when X-rays and computer tests revealed instead it was a mummy of a woman who had been seven months pregnant.

An analysis of Twitter activity between March 1 and Aug. 1, 2020, found strong support by U.S. users for wearing face coverings and that a media focus on anti-mask opinions fueled the rhetoric of those opposed, report University of Oregon researchers.

Dismissed a decade ago as far-fetched and dangerous, schemes to tame the effects of global warming by engineering the climate have migrated from the margins of policy debates towards centre stage.

Researchers at Imperial have been developing a novel method of detecting the presence of an elusive species, the hazel dormouse.

Technology that was first used to distinguish healthy tissues from cancerous ones in humans has been successfully used to identify insects.

Reservoirs are indispensable for global drinking water supply. To protect them from silting, overfertilization, and pollution, anticipating monitoring of water quality is required. A Brazilian-German consortium led by Karlsruhe Institute of Technology (KIT) has now developed user-friendly measurement and monitoring methods that are particularly suited for regions with limited data availability. Among others, project results confirm the big effect of reforestation in the reservoir catchment.

Technical progress has also found its way into the nature experience of recreational angling. Device innovations such as echo sounders, underwater cameras or drones make it easier to track and catch fish. An international team with Professor Robert Arlinghaus from the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) and the Humboldt Universität zu Berlin has summarized in a study how technical innovations can affect anglers, fisheries management and fish populations. The researchers... Читать дальше...

As part of a laboratory experiment, Rebecca Holmes examined water bottles that had been acquired from abroad expecting to find bisphenol A (BPA), a human-made component commonly found in polycarbonate plastics used to make consumer products.

A team of researchers from Universidade Estadual Paulista, Universidade Federal do Mato Grosso do Sul and Projeto Dacnis, São Francisco Xavier and Ubatuba has discovered a new species of pumpkin toadlet. In their paper published on the open-access site PLOS ONE, the group describes their study of pumpkin toadlets in Brazil, how they found the new species and what sets it apart from other pumpkin toadlets.

An animal scientist with Wageningen University & Research in the Netherlands has created an artificial-intelligence-based application that can gauge the emotional state of farm animals based on photographs taken with a smartphone. In his paper uploaded to the bioRxiv preprint server, Suresh Neethirajan describes his app and how well it worked when tested.

Germany's glaciers are melting at a faster pace than feared and the country could lose its last ice caps in 10 years, an alarming report said Thursday.

Adult mantis shrimp pack an explosive punch that can split water, but no crustacean emerges fully formed. Minute larvae can undergo six or seven transformations before emerging as fully developed adults and limbs and maneuvers develop over time. So, when do mantis shrimp larvae acquire the ability to pulverize their dinner and how powerful are the punches that these mini crustaceans pack? "We knew that larval mantis shrimp have these beautiful appendages; Megan Porter and Eve Robinson at the University... Читать дальше...

A team of researchers affiliated with several institutions in China and one in the U.S. has found evidence of multiple novel Asgard MAGs that expands the phylogenetic diversity of Asgard. In their paper published in the journal Nature, the group describes their analysis of multiple complete or mostly complete genomes of Asgard archaea.

Antibiotic resistance poses a serious threat to human health. Resistant infections now cause more than 750,000 deaths per year and are predicted to increase to 10 million deaths per year by 2050. It is known that treating patients with antibiotics is associated with the emergence of resistance—and worse outcomes for patients. But how resistance emerges during infections remains poorly understood.

The Sustainability Consortium released Wednesday, April 28, the report "Project WearEver: Demonstrating the Feasibility of Using Digital Tags to Measure Clothing Use," in collaboration with Arizona State University, North Carolina State University and the U of A. The report follows the 2019-2020 pilot project, called Project WearEver, that concluded the following findings:

With the global population predicted to reach 9.7 billion by 2050, one of the biggest challenges in our lifetimes will be securing enough food for everyone.

Researchers from Osaka University, Japan and the University of Adelaide, Australia have worked together to produce the new multiplexer made from pure silicon for terahertz-range communications in the 300-GHz band.
