Climate change and habitat destruction may have already caused the loss of more than one-tenth of the world's terrestrial genetic diversity, according to new research. This means that it may already be too late to meet the United Nations' proposed target, announced last year, of protecting 90 percent of genetic...
Clarifying the chaos of narwhal behavior
Chaos theory improves understanding of Arctic narwhal behavior, with the aim of helping efforts to protect this vulnerable species.
Monkeypox outbreaks associated with human-to-human transmission outside endemic areas
Since May 2022, cases of monkeypox have increased globally, stirring fears of a new pandemic. A new study presents synthesized descriptions of its clinical characteristics, risk factors, infection control and prevention measures, as well as potential treatments.
Anthropogenic air pollution more significant than desert dust
At the beginning of the year, the World Health Organization (WHO) announced that the Middle East ranks among the regions with the worst air quality. There is a common misconception that desert dust is the most significant cause of air pollution from particulate matter in this region, but a new...
An integrated modeling framework to assess surface and ground water resources
In a new study, researchers applied a large-scale model linking surface water to groundwater, which can be used for estimating water resources at a high spatial resolution.
RNA-editing tool a fast, sensitive test for COVID-19
Researchers have modified a gene editing tool to serve as a highly sensitive diagnostic test for the presence of the SARS-CoV-2 virus.
Shaking the dinosaur family tree: How did ‘bird-hipped’ dinosaurs evolve?
Researchers have conducted a new analysis of the origins of 'bird-hipped' dinosaurs -- the group which includes iconic species such as Triceratops -- and found that they likely evolved from a group of animals known as silesaurs, which were first identified two decades ago.
Food for our guts: Human microbes feed on plant sugars
A carbohydrate commonly found attached to plant proteins is a food source for the bacteria in our gut, new research suggests.
Gut microbiomes help bears with very different diets reach the same size
A recent study of the gut microbiome of Alaskan brown bears (Ursus arctos) shows that the microbial life in bears' guts allows them to achieve comparable size and fat stores while eating widely different diets. The work sheds light on the role of the gut microbiome in supporting health in...
Sifting through cellular recycling centers
A new method allows scientists to determine all the molecules present in the lysosomes -- the cell's recycling centers -- of mice. This could bring new understanding and treatment of neurodegenerative disorders.
