A study published in Advances in Atmospheric Sciences has revealed the unprecedented nature of an anticyclonic anomaly that occurred over Northeast Asia in July 2021. It not only played a pivotal role in the catastrophic extreme precipitation experienced in Henan Province in central China, but also caused a prolonged and intense marine heat wave in the Japan Sea—the strongest event of its kind in the western North Pacific in the past four decades.

An international team, including Western astrophysicists Els Peeters and Jan Cami, has found the destruction and re-formation of a large quantity of water in a planet-forming disk located at the heart of the Orion Nebula.

A material coating, whose light refraction properties can be precisely switched between different states, has been developed by an interdisciplinary research team from the Chemistry and Physics departments at the University of Jena. The team, led by Felix Schacher, Sarah Walden, Purushottam Poudel, and Isabelle Staude, combined polymers that react to light with so-called metasurfaces.

A new technique for electrospinning sponges has allowed scientists from the University of Surrey to directly produce 3D scaffolds—on which skin grafts could be grown from the patient's own skin.

Undersea anchors of ice that help prevent Antarctica's land ice from slipping into the ocean are shrinking at more than twice the rate compared with 50 years ago, research shows.

An international team of scientists from China, the U.S. and Europe has studied new fossils of the marine reptile Dinocephalosaurus orientalis. This research has made it possible to fully describe the bizarre, very impressive animal for the first time.

Researchers from Goethe University Frankfurt and the Senckenberg Biodiversity and Climate Research Center have modeled the spatial distributional patterns of black flies in Hesse, North Rhine-Westphalia, Rhineland-Palatinate and Saxony for the first time.

The evolutionary success of the first large predators on land was driven by their need to improve as killers, researchers at the University of Bristol and the Open University suggest.

In recent news, there has been a case where a patient experienced pain due to a surgical procedure involving sutures, resulting in the unintended presence of gauze within the patient's body. Gauze is typically employed to control bleeding during medical interventions, aiding in hemostasis. However, when inadvertently left in the body, it can lead to inflammation and infection.

Among the fastest-declining birds in the world, African vultures battle many of the problems commonly plaguing wildlife today, such as habitat loss, hunting, and poisoning, but they also face a more unique set of obstacles.

According to new research from Rice University and the University of Nebraska at Omaha, conservative-leaning job applicants indicate being less likely to pursue positions that require personal statements on diversity, equity and inclusion (DEI), and those negative reactions are not independent of anti-Black racism.

The federal Environmental Protection Agency has notified counterparts at the Georgia Environmental Protection Division that they believe the state may be allowing Georgia Power to store toxic coal ash in ways that are "less protective" than federal standards require.

The synthesis of proteins in the cell is a key process of life. By this means, the genetic code of the genome is translated into the amino acid sequence of proteins. The process is complex—and has been studied in detail for decades.

How long it takes for cells to close a fruit fly's wound can tell us a lot about the healing process in the early developmental stages of humans, and potentially treatments that prevent long-term damage.

Human cells contain ribosomes, a complex machine that produces proteins for the rest of the body. Now the researchers have come closer to understanding how the ribosome works.

In living cells, a vast number of transient events occur simultaneously, each of them important for a given cell in carrying out its function. The faithful recording of these transient activities is a prerequisite for a molecular understanding of life, yet obtaining such recordings is extremely challenging.

A multi-institutional team of archaeologists and paleontologists has unearthed and identified a new species of mammal from the Maastrichtian age. In their paper published in the journal Scientific Reports, the researchers note that the mammal was much larger than any other known examples of its kind.

Networks can represent changing systems, like the spread of an epidemic or the growth of groups in a population of people. But the structure of these networks can change, too, as links appear or vanish over time. To better understand these changes, researchers often study a series of static "snapshots" that capture the structure of the network during a short duration.

Student enrollment in districts that provided in-person schooling in fall 2020 during the COVID-19 pandemic showed a greater decline among nonwhite students than white students.

The use of pesticides, while beneficial for global food security, wreaks havoc on natural ecosystems and human health. To address this issue, Penn State researchers have turned to an unlikely enforcer to protect crops: the ladybug. The team, led by Sara Hermann in the Penn State College of Agricultural Sciences, developed a novel pest management tool by leveraging the chemical ecology of predator-prey interactions between ladybugs and aphids.

Streams with ample connections to shallow groundwater flowpaths have greater microbial diversity and are more effective at preventing toxic forms of metals—often products of upstream mining—from entering and being transported downstream. These streams are also better at detoxifying those metals already present.

A small international team of animal behavior researchers has found that species of glass frogs whose males help care for offspring tend to have smaller testes than species whose males do not help care for offspring. In their study, published in the journal Proceedings of the Royal Society B, the group went into the tropical rain forests in Ecuador and Brazil to study the behavior of glass frogs over the course of several months.

While analyzing the data from the Next Generation Transit Survey (NGTS), an international team of astronomers has discovered a new brown dwarf. The newfound object, designated NGTS-28Ab, orbits its host star in just about 30 hours. The finding was reported in a paper posted February 15 on the preprint server arXiv.

Whiteflies, particularly the African cassava whitefly (Bemisia tabaci, SSA1-SG1), pose a significant threat to agricultural productivity in sub-Saharan Africa by transmitting viruses that cause cassava brown streak disease and cassava mosaic virus disease. In a new study published in PeerJ, Dr. Tadeo Kaweesi and his team at the National Agricultural Research Organization identify potential gene targets that could revolutionize the management of this devastating pest and prove vital for food security in the region.

In its fight against invasive aquatic plants in the Sacramento-San Joaquin River Delta, the California State Parks' Division of Boating and Waterways says it will begin a regiment of herbicide treatments that will last through the end of 2024.
