A new study traces the origins of Piscine orthoreovirus to Atlantic salmon farms in Norway and finds that the virus is now almost ubiquitous in salmon farms in British Columbia, Canada.

Scientists summarize, compare and contrast research in learned robot manipulation through the lens of adaptability and outline promising research directions for the future.
Inhalable nanobodies targeting the spike protein of SARS-CoV-2 can prevent and treat severe COVID-19 in hamsters, according to new research.
Solitary river otters in Brazil use a rich repertoire of vocalizations during play and conflict, according to a new study.
Researchers have gained new insight into the workings of perovskites, a semiconductor material that shows great promise for making high-efficiency, low-cost solar cells and a range of other optical and electronic devices.
Bacteria called methylotrophs can use methane and methanol as fuel; in doing so, they produce large amounts of formaldehyde during growth, but until recently no one knew how they detected and responded to this toxic compound. Researchers describe their discovery of a novel formaldehyde sensor in the bacterium Methylorubrum extorquens, and other methylotrophs.
Researchers studied the evolution of Tasmanian devils in response to a unique transmissible cancer. The team found that historic and ongoing evolution are widespread across the devils' genome, but there is little overlap of genes between those two timescales. These findings suggest that if transmissible cancers occurred historically in devils, they imposed natural selection on different sets of...
The immune system's attempt to eliminate Salmonella bacteria from the gastrointestinal (GI) tract instead facilitates colonization of the intestinal tract and fecal shedding, according to scientists.
Scientists have got up close and personal with human sewage to determine how best to measure hidden and potentially dangerous plastics.
In cities, heavy rains wash away the gunk collecting on sidewalks and roads, picking up all kinds of debris. However, the amount of microplastic pollution swept away by this runoff is currently unknown. Now, researchers report that stormwater can be a large source of microplastics and rubber fragments to water bodies and, with a proof-of-concept experiment, show that a rain garden could keep these...
There has long been controversy about whether the world's highest region, Tibet, has grown taller during the recent geological past. New results indicate that the 'Roof of the World' appears to have risen by up to 600 meters and the answer was found in underwater lava. The knowledge sheds new light on Earth's evolution.
A new study found that specific types of gut bacteria can protect other good bacteria from cancer treatments -- mitigating harmful, drug-induced changes to the gut microbiome. By metabolizing chemotherapy drugs, the protective bacteria could temper short- and long-term side effects of treatment.
People who eat too many refined carbs and fatty meats for dinner have a higher risk of heart disease than those who eat a similar diet for breakfast, according to a nationwide study.
Travelling elephants pay close attention to scent trails of dung and urine left by other elephants, new research shows.
Researchers have found that normal exposure to light can drive the formation and growth of optic nerve tumors in mice -- and maybe people -- with a genetic predisposition. Such tumors can lead to vision loss.
Electric fish pause before sharing something particularly meaningful. Pauses also prime the sensory systems to receive new and important information. The study reveals an underlying mechanism for how pauses allow neurons in the midbrain to recover from stimulation.
It's well known that reptiles depend on temperature cues while in the egg to determine a hatchling's sex. Now, researchers say that embryos of many different animal species also rely on acoustic signals in important ways. They call this phenomenon 'acoustic developmental programming.'
Researchers have used 'swarm learning' - a novel, artificial intelligence technology - to detect blood cancer, lung diseases and COVID-19 in data stored in a decentralized fashion.
Researchers developed a 'Digger Finger' robot that digs through granular material, like sand and gravel, and senses the shapes of buried objects. The technology could aid in disarming buried bombs or inspecting underground cables.
When enjoying a chocolate bar, most people don't think about how the molecules within it are organized. But different arrangements of the fats in chocolate can influence its taste and texture. Now, researchers have found that the side of a chocolate bar facing the mold has a more orderly crystalline structure than the side facing air, knowledge that might help chocolatiers produce tastier...
New research confirms people visit places more frequently when they have to travel shorter distances to get there. The study establishes a 'visitation law' and could help in urban planning.
Researchers have conducted two of the first studies in New England to collectively show that toxic human-made chemicals called PFAS (per-and polyfluoroalkyl substances), found in everything from rugs to product packaging, end up in the environment differently after being processed through wastewater treatment facilities -- making it more challenging to set acceptable screening levels.
Sleep scientists assessed how effective caffeine was in counteracting the negative effects of sleep deprivation on cognition.
Fishery and aquaculture have given rise to an enormous uniformity in the diversity of bivalves along the more than 18,000 kilometer long Chinese coast, biologists report.
Inspired by insects that suck nutrients directly from plant veins, physicists have studied whether valuable chemical substances can be harvested directly from the cells of plants. Using a harvester measuring only a few microns, they have now achieved a technological breakthrough.
