| Invasive species alters marine community, interferes in post-disaster recovery Posted: 10 May 2021 04:25 PM PDT Clavelina oblonga, an invasive marine fouling species, not only reduces diversity in communities it invades, it also interferes in their recovery following natural disasters - a process known as 'succession.' |
| Time running out to save coral reefs Posted: 10 May 2021 01:15 PM PDT New data on the growth rates of coral reefs shows there is still a window of opportunity to save them from eroding by mid-century -- but time is running out. |
| Ocean-bottom sediments tell a story about ancient Greenland summers Posted: 10 May 2021 01:15 PM PDT The study uses leaf wax chemicals in the deposits to learn about ancient climate in southern Greenland, focusing on summer temperature during periods of relative warmth on Earth, called interglacials, over the past 600,000 years. |
| Animal production responsible for vast majority of air quality-related health impacts from U.S. food Posted: 10 May 2021 01:15 PM PDT Poor air quality caused by food production in the U.S. is estimated to result in 16,000 deaths annually, 80% of which are related to animal production, according to a new study. The study also shows how improving animal and crop management practices, as well as how eating more plant-rich diets, can substantially reduce mortality from food-related air pollution. |
| The next generation of hunters could look different Posted: 10 May 2021 11:39 AM PDT A new survey found that the future of hunting in the United States might look different than it has in the past. |
| As global climate shifts, forests' futures may be caught in the wind Posted: 10 May 2021 10:32 AM PDT Forests' ability to adapt to the disruptions wrought by climate change may depend, in part, on the eddies and swirls of global wind currents, suggests a new study. The study compared global wind patterns with previously published genetic data of nearly 100 tree and shrub species collected from forests around the world, finding significant correlations between wind speed and direction and genetic diversity throughout our planet's forests. |
| Scientists develop better way to block viruses that cause childhood respiratory infections Posted: 10 May 2021 10:31 AM PDT By engineering a short chunk of protein, or peptide, that can prevent the attachment of human parainfluenza viruses to cells, researchers have improved a method in rodent models intended to help keep children healthy. |
| Esophageal cancers resurrect ancient retroviruses hidden in our genome Posted: 10 May 2021 08:36 AM PDT Scientists have found that many esophageal cancers turn on ancient viral DNA embedded in our genome, a finding that could lead to improvements in immunotherapy. |
| Implanted wireless device triggers mice to form instant bond Posted: 10 May 2021 08:35 AM PDT Researchers have wirelessly programmed -- and then deprogrammed -- mice to socially interact with one another in real time. The advancement is thanks to an ultraminiature, wireless, battery-free and fully implantable device that uses light to activate neurons. |
| Long-term stress in dogs linked to the owner-dog relationship Posted: 10 May 2021 08:35 AM PDT The relationship a dog has with its owner is related to its stress level. This is the conclusion of a newly published study. The results also suggest that the link between stress and the owner's personality traits differs between dog breeds. |
| New vaccine blocks COVID-19 and variants, plus other coronaviruses Posted: 10 May 2021 08:35 AM PDT A potential new vaccine has proven effective in protecting monkeys and mice from a variety of coronavirus infections -- including SARS-CoV-2 as well as the original SARS-CoV-1 and related bat coronaviruses that could potentially cause the next pandemic. |
| Friendly pelicans breed better Posted: 10 May 2021 08:35 AM PDT Captive pelicans that are free to choose their own friendships are more likely to breed successfully on repeated occasions, new research suggests. |
| Microneedle patch delivers antibiotics locally in the skin Posted: 10 May 2021 08:35 AM PDT MRSA skin infections are often treated with intravenous injection of antibiotics, which can cause significant side effects and promote the development of resistant bacterial strains. To solve these problems, researchers are developing a microneedle patch that delivers antibiotics directly into the affected skin area. New results show that the microneedle patch effectively reduces MRSA bacteria in the skin. |
| How Legionella makes itself at home Posted: 10 May 2021 08:35 AM PDT Scientists have discovered a key protein that helps the bacteria that causes Legionnaires' disease to set up house in the cells of humans and other hosts. The findings could offer insights into how other bacteria are able to survive inside cells, knowledge that could lead to new treatments for a wide variety of infections. |
| Posted: 10 May 2021 07:44 AM PDT The process of combining maternal and paternal genetic information is surprisingly error-prone. |
| São Tomé island has two species of caecilians found nowhere else on Earth Posted: 10 May 2021 07:43 AM PDT A new study indicates São Tomé island has two species of caecilians found nowhere else on Earth. The research adds evidence to a century-long scientific debate and reveals how volcanic activity may have driven the divergence of the limbless amphibians. |
| In soil, high microbial fluctuation leads to more carbon emissions Posted: 10 May 2021 07:43 AM PDT Modeling shows fluctuating soil microbial populations impact how much carbon is released from soil. |
| Firefighting chemical found in sea lion and fur seal pups Posted: 10 May 2021 07:43 AM PDT A chemical that the New South Wales government has recently partially banned in firefighting has been found in the pups of endangered Australian sea lions and in Australian fur seals. The finding represents another possible blow to Australian sea lions' survival. Hookworm and tuberculosis already threaten their small and diminishing population, which has fallen by more than 60 percent over four decades. |
| Reaching your life goals as a single-celled organism Posted: 10 May 2021 07:43 AM PDT How is it possible to move in the desired direction without a brain or nervous system? Single-celled organisms apparently manage this feat without any problems: for example, they can swim towards food with the help of small flagellar tails. A research team has now been able to simulate this process on the computer. |
| TB immune response discovery could significantly reduce disease harm Posted: 10 May 2021 07:43 AM PDT A pioneering study has discovered the presence of a harmful inflammatory protein in patients with symptomatic tuberculosis (TB). Researchers say, by targeting the IL-17 cytokine, a component produced naturally by the immune system in response to infection, excessive and damaging lung inflammation caused by TB may be significantly reduced to help speed up patient recovery. |
| Could wider use of gene reserves protect rare species? Posted: 10 May 2021 05:59 AM PDT UK landowners and conservationists welcome wider-spread use of Gene Conservation Units (GCUs) to help protect some of the rarest plants and insects, research has shown. |
| Sharks in protected area attract illegal fishers Posted: 10 May 2021 05:58 AM PDT Thousands of sharks have been illegally caught in a Marine Protected Area (MPA) in the Indian Ocean, new research shows. |
| Research results challenge a decades-old mechanism of how we hear sounds Posted: 10 May 2021 05:58 AM PDT Researchers have made several discoveries on the functioning mechanisms of the inner hair cells of the ear, which convert sounds into nerve signals that are processed in the brain. The results challenge the current picture of the anatomical organization and workings of the hearing organ, which has prevailed for decades. |
| Vegetarians have healthier levels of disease markers than meat-eaters Posted: 09 May 2021 12:38 PM PDT Vegetarians appear to have a healthier biomarker profile than meat-eaters, and this applies to adults of any age and weight, and is also unaffected by smoking and alcohol consumption, according to a new study in over 166,000 UK adults. |
| How proteins control information processing in the brain Posted: 09 May 2021 12:38 PM PDT A complicated interaction between different proteins is needed for information to pass from one nerve cell to the next. Researchers have now managed to study this process in the synaptic vesicles, which play an important role in this process. |
