New research published in the Journal of Anatomy has used dental evidence to challenge the origin time of mammals.
Southern right whales come to Australian shores to breed and calve during the cooler months but their whereabouts during the summer has remained a long-standing mystery, until now.
Researchers have spent 30 years searching the rugged Kimberley region of Western Australia for orchids, with their work finally culminating in a paper published in Telopea.
In an Australian first, scientists from Edith Cowan University (ECU) have determined how long it takes for seagrass to recover after grazing by swans.
Portal origin URL: Artificial Gravity Provides Partial Protection for Biology in SpacePortal origin nid: 482569Published: Tuesday, September 6, 2022 - 12:56Featured (stick to top of list): noPortal text teaser: New findings from a study using fruit flies on the International Space Station suggest that space travel has an impact on the central nervous system, but that...
Exploring novel topological materials and related phase transitions has been a central research theme in condensed matter physics and materials science. Topological materials with nontrivial anti-band crossings have attracted much attention. Hourglass fermion surface state, located at the vertex in the neck of an hourglass-like dispersion, enables exploration of remarkable topological phases, such...
When two metal surfaces slide against each other, a variety of complicated phenomena occur that lead to friction and wear: Small crystalline regions, of which metals are typically composed, can be deformed, twisted or broken, or even fuse together. It is important for industry to understand such effects. After all, wear can destroy machinery and cost a lot of money.
Key studies in the last decade have shown that the gut microbiome, the collection of hundreds of bacterial species that live in the human digestive system, influences neural development, response to cancer immunotherapies, and other aspects of health. But these communities are complex and without systematic ways to study the constituents, the exact cells and molecules linked with certain diseases...
During heavy rains, Hawaii's streams, rivers, and nearshore waters change on microscopic levels. Bacteria in these aquatic systems increase, and some of these bacteria can be harmful to human health. They can cause problems like gastroenteritis—also known as the stomach flu—as well as skin and respiratory diseases.
Risk management has reduced the vulnerability to floods and droughts around the world, but their impact is still increasing worldwide, according to a study published in the journal Nature, which includes the participation of the researcher María del Carmen Llasat, professor of Atmospheric Physics at the Faculty of Physics and member of the Water Research Institute (IdRA) of the University of...
A team of researchers led by Anca Dorhoi at the Friedrich-Loeffler-Institut (FLI) and Emmanuel Saliba at the Helmholtz Institute for RNA-based Infection Research (HIRI), has elucidated age-dependent variations in cellular immunity in Rousettus aegyptiacus, known as the Egyptian fruit bat, a natural reservoir for filoviruses such as Marburg Virus.
The changing seasons tell us much about the workings of nature. Now, a research group from Japan has discovered that the seasonal changes of tree leaf growth and shedding can have a big influence on climate even on small, local scales.
Unprecedented and societally disruptive extreme weather events, including heat waves, droughts, dust storms and torrential rains, will soon become a reality unless immediate, ambitious, and transboundary climate action is taken, warns the latest scientific assessment of state-of-climate in the region.
The drummers puff out their chests, let out a guttural yell, then step up to their kits and furiously pound out their signature beat so that everyone within earshot can tell who is playing.
Switzerland's biggest retailer launched a new coffee machine invention on Tuesday—fully compostable coffee balls which it hopes will shake up the global market and take on Nespresso's global dominance.
A team of scientists, led by the University of Bristol, has uncovered intriguing new insights into the diet of people living in Neolithic Britain and found evidence that cereals, including wheat, were cooked in pots.
In a first, scientists have captured on video all the steps a virus follows as it enters and infects a living cell in real time and in three dimensions.
Alpine ecosystems are under intense pressure from pest species, but University of Otago research has highlighted how the mountains themselves can be used to help eradicate them.
Some species of tardigrades, or water bears as the tiny aquatic creatures are also known, can survive in different environments often hostile or even fatal to most forms of life. For the first time, researchers describe a new mechanism that explains how some tardigrades can endure extreme dehydration without dying. They explored proteins that form a gel during cellular dehydration. This gel...
A study published in the journal PLOS ONE could one day help health workers determine whether bacteria of the species Streptococcus pneumoniae, which cause meningitis—an inflammation of the membranes that envelop the brain and spinal cord—are resistant to antibiotics.
Old-growth forests and managed forests with old-growth characteristics can provide relief from climate change for some bird species, research by the Oregon State University College of Forestry suggests.
