Marine scientists assessed the risk posed by small-scale fisheries to all 72 species of toothed whales found throughout the world's oceans. They found that this risk was highest in the Central Indo-Pacific, Temperate Northern Pacific, Temperate South America and the Western Indo-Pacific.

Researchers at the University of Cambridge have identified two subgroups of adolescents who self-harm and have shown that it is possible to predict those individuals at greatest risk almost a decade before they begin self-harming.

Although stimulated-emission depletion (STED) microscopy was a true breakthrough for observing the morphology of live neurons at higher resolution, there is still room for improvement. In a recent study published in Neurophotonics, a team of scientists led by Dr. U. Valentin Nägerl from Université de Bordeaux developed a simple yet effective calibration method that allows for more precise STED imaging at higher tissue depths.

Scientists developed layered double hydroxide (LDH) membrane with high hydroxide conductivity and ion selectivity for alkaline-zinc iron flow battery.

Solar activities, such as CME(Coronal Mass Ejection), cause geomagnetic storm that is a temporary disturbance of the Earth's magnetosphere. Geomagnetic storms can affect GPS positioning, radio communication, and power transmission system. Solar explosions also emit radiation, which can affect satellite failures, radiation exposure to aircraft crew, and space activity. Therefore, it is important to understand space weather phenomena and their impact on the Earth.

Researchers have succeeded for the first time in demonstrating the role of hypothalamic astrocytes in obesity-related hypertension. In addition, they showed that the hormone leptin is involved in the increase of blood vessels in the hypothalamus of obese mice, contributing of hypertension. Helmholtz Zentrum München led the study and collaborated with Ludwig-Maximilians-Universität München, the Technical University of Munich and the German Diabetes Center.

The biological and historical diversity in museum collections is staggering, with specimens collected across centuries by some of the most famous scientists in history. In a new study, researchers from the University of Copenhagen successfully revived museal fungal specimens that were more than 250 years old and used the live cultures for whole genome sequencing and physiological experiments.

New results allow the development of novel therapies for hereditary forms of intestinal cancer.

Researchers from Osaka University used innovative imaging techniques to demonstrate symmetric collective alignment of nuclei in the muscle cells of the anterior midgut of the Drosophila embryo. This 'collective nuclear behavior' further influences bilateral asymmetry in the development of internal organs. A clear understanding of the factors that influence the shape and location of viscera will help inform future research into experimental, and eventually therapeutic, organ regeneration technology.

Rising numbers of liver cancer in Aboriginal and Torres Strait Islander communities has led experts at Flinders University to call for more programs, including mobile liver clinics and ultrasound in rural and remote Australia. The Australian study just published in international Lancet journal EClinicalMedicine reveals the survival difference was largely accounted for by factors other than Indigenous status - including rurality, comorbidity burden and lack of curative therapy.

Conditions during Baltic herring spawning may have cascading effects on the whole Baltic ecosystem.

Researchers from The Australian National University (ANU) have developed new technology that allows people to see clearly in the dark, revolutionising night-vision.

In a new study, the researchers found that the common respiratory virus jump-starts the activity of interferon-stimulated genes, early-response molecules in the immune system which can halt replication of the SARS-CoV-2 virus within airway tissues infected with the cold.

New research shows pregnant women exposed to higher levels of air pollution have babies who grow unusually fast in the first months after birth, putting on excess fat that may put them at risk of obesity and related diseases later in life.

A new study from US Department of Veterans Affairs, Regenstrief Institute and IUPUI researchers reports that electronic health records (EHRs) are not rising to the challenges faced by primary care physicians because EHRs have not been designed or tailored to their specific needs. The study authors recommend implementing a human factors approach to the design or redesign of EHR user interfaces.

State-of-the-art video microscopy has enabled Australian researchers to see the molecular details of how malaria parasites invade red blood cells - a key step in the disease.

Adults who skip breakfast are likely to miss out on key nutrients that are most abundant in the foods that make up morning meals, a new study suggests.

Research by Oregon State University suggests a pair of compounds originating from hops can help thwart a dangerous buildup of fat in the liver known as hepatic steatosis.

Artificial intelligence (AI) may offer a way to accurately determine that a person is not infected with COVID-19. An international retrospective study finds that infection with SARS-CoV-2, the virus that causes COVID-19, creates subtle electrical changes in the heart. An AI-enhanced EKG can detect these changes and potentially be used as a rapid, reliable COVID-19 screening test to rule out COVID-19 infection.

Many cosmetics sold in the United States and Canada likely contain high levels of per- and polyfluoroalkyl substances (PFAS), a potentially toxic class of chemicals linked to a number of serious health conditions, according to new research from the University of Notre Dame.
