| Researchers pinpoint how Zika virus evades cell's antiviral response Posted: 18 Jan 2022 12:48 PM PST In a new study of the Zika virus, scientists have discovered a key mechanism used by the virus to evade the antiviral response of the cell it is attacking. This finding contributes to a better understanding of how viruses infect cells, overcome immune barriers and replicate -- information that is essential for fighting them. |
| Research team identifies new mechanism for protecting DNA Posted: 18 Jan 2022 12:48 PM PST Researchers have identified a new mechanism by which a protein known for repairing damaged DNA also protects the integrity of DNA by preserving its structural shape. The discovery, involving the protein 53BP1, offers insight into understanding how cells maintain the integrity of DNA in the nucleus, which is critical for preventing diseases like premature aging and cancer. |
| How a contagious cancer spread among clams Posted: 18 Jan 2022 11:59 AM PST A contagious blood cancer jumped from one species of clam to another and spread among clams living in the Atlantic Ocean and Mediterranean Sea, shows a new study. |
| Study highlights connections between addictive drugs and brain function in mice Posted: 18 Jan 2022 11:43 AM PST Researchers used high-resolution technologies to see how dopamine circuitry in mice is affected by addictive drugs. The results answered older structural questions, while raising new ones about plasticity and recovery in the brain. |
| Why did ocean productivity decline abruptly 4.6 million years ago? Posted: 18 Jan 2022 09:51 AM PST By drilling deep down into sediments on the ocean floor researchers can travel back in time. A research team now presents new clues as to when and why a period often referred to as the 'biogenic bloom' came to an abrupt end. Changes in the shape of the Earth's orbit around the Sun may have played a part in the dramatic change. |
| Increase in marine heat waves threatens coastal habitats Posted: 18 Jan 2022 09:51 AM PST Heat waves -- like the one that blistered the Pacific Northwest last June -- also occur underwater. A new study paints a worrisome picture of recent and projected trends in marine heat waves within the nation's largest estuary, with dire implications for the marine life and coastal economy of the Chesapeake Bay and other similarly impacted shallow-water ecosystems. |
| Halting antibiotic resistance is a little less futile Posted: 18 Jan 2022 09:35 AM PST Bioscientists develop a microfluidic platform for high-throughput studies of how bacteria evolve antibiotic resistance. |
| Posted: 18 Jan 2022 08:14 AM PST Boxing up molecular machines. The construction of a molecular rotor inside a nanostructured cage allows for the development of a tunable molecular device. |
| Automating blood smears for easier malaria diagnosis Posted: 18 Jan 2022 08:13 AM PST Researchers have developed devices to automate blood smears. Their devices, called autohaem smear and smear+, can consistently create high-quality smears equivalent to those created by human experts, automating the smearing process so every smear is correct and consistent. A key goal of the project was to make the devices accessible to as many people as possible, so the researchers designed their devices to be easy to build, using readily available or 3D-printed components. |
| A giant panda’s gut bacteria help it remain chubby while on a bamboo diet Posted: 18 Jan 2022 08:13 AM PST The giant panda feeds exclusively on fibrous bamboo, yet they still manage to stay chubby and healthy. Researchers reveal that shifts in the bear's gut microbiota in the season when nutritious bamboo shoots become available helps the herbivorous bear gain more weight and store more fat, which may compensate for the lack of nutrients in seasons when there are only bamboo leaves to chew on. |
| Owl wing design reduces aircraft, wind turbine noise pollution Posted: 18 Jan 2022 08:13 AM PST Researchers used the characteristics of owl wings to inform airfoil design and significantly reduce trailing-edge noise. The team used noise calculation and analysis software to conduct a series of detailed theoretical studies of simplified airfoils with characteristics reminiscent of owl wings. They applied their findings to suppress the noise of rotating machinery. Improving the flow conditions around the trailing edge and optimizing the shape of the edge suppressed the noise. |
| Sunflowers’ invisible colors help them attract bees and adapt to drought Posted: 18 Jan 2022 07:41 AM PST It turns out sunflowers are more than just a pretty face: the ultraviolet colours of their flowers not only attract pollinators, but also help the plant regulate water loss. |
| Nutritional value of huhu grubs assessed Posted: 18 Jan 2022 07:41 AM PST Huhu grubs have long been prized as a traditional food source and their nutritional value has just been analysed. |
| Scientists identify therapeutic target for Epstein-Barr virus Posted: 18 Jan 2022 07:41 AM PST A new study has identified a new potential pathway for developing therapeutics that target Epstein-Barr virus (EBV). |
| Saving species through genomics in megadiverse Colombia Posted: 18 Jan 2022 07:41 AM PST Colombia stands to benefit ecologically, economically and socially through membership in the Earth Biogenome Project. |
| Smart soil bugs offer farmers an ecofriendly route to controlling crop diseases Posted: 18 Jan 2022 07:41 AM PST An innovative method of controlling a range of damaging crop diseases using native, beneficial soil bacteria has emerged from a research-industry collaboration. |
| Researchers explore ways to make hatchery steelhead more like wild fish Posted: 18 Jan 2022 07:41 AM PST Hatchery-raised steelhead trout have offspring that are good at gaining size under hatchery conditions but don't survive as well in streams as steelhead whose parents are wild fish, new research shows. |
| Posted: 18 Jan 2022 06:41 AM PST Climate change will force 45 per cent of the fish stocks that cross through two or more exclusive economic zones to shift significantly from their historical habitats and migration paths by 2100, a challenge that may lead to international conflict, according to a new study. |
| Celebrated malting barley came from a single plant Posted: 18 Jan 2022 05:54 AM PST The 200-year-old malting barley variety 'Chevalier' was for a long time world-leading in beer brewing and is thought to have originated from a single plant. In a new study, researchers have investigated this claim. They have analyzed seed samples that are older than 150 years using molecular genetic methods. The results give a revealing insight into the plant breeding of times gone by. |
| Earth BioGenome Project begins genome sequencing in earnest Posted: 17 Jan 2022 01:55 PM PST The Earth BioGenome Project is a global effort to map the genomes of all plants, animals, fungi and other microbial life on Earth. The EBP is entering a new phase as it moves from pilot projects to full-scale production sequencing. |
| In the Atlantic Forest, the lowland tapir is at risk of extinction Posted: 17 Jan 2022 05:58 AM PST Lowland tapir populations in the Atlantic Forest in South America are at risk of almost complete disappearance, scientists have estimated. The main long-term threat to their well-being is population isolation, as hunting and highways keep populations away from each other. Urgent measures need to be taken to connect isolated populations and ensure the long-term conservation of tapirs, warn the authors of a new study. |
