| Clever biomolecular labelling enables identification of immune cells Posted: 07 Jun 2021 05:22 PM PDT Biomolecules regulate the biological functions inside every living cell. If scientists can understand the molecular mechanisms, then it is possible to detect severe dysfunction. At a molecular level, this can be achieved with fluorescent markers that are incorporated into the respective biomolecules. Researchers are now able to show that a complex of manganese makes it possible to conveniently label certain biomolecules. |
| Massive plankton blooms with very different ecosystem impacts Posted: 07 Jun 2021 05:22 PM PDT "The big mystery about plankton is what controls its distribution and abundance, and what conditions lead to big plankton blooms," according to the author of a new study. Researchers explore this question and provide examples of conditions that lead to massive plankton blooms with vastly different potential impacts on the ecosystem. |
| Climate change a bigger threat to landscape biodiversity than emerald ash borer Posted: 07 Jun 2021 05:22 PM PDT Despite the devastating impact the emerald ashborer beetle has had on forests in the eastern and midwestern parts of the U.S., climate change will have a much larger and widespread impact on these landscapes through the end of the century, according to researchers. |
| Monoclonal antibody prevents HIV infection in monkeys, study finds Posted: 07 Jun 2021 05:22 PM PDT The experimental, lab-made antibody leronlimab can completely prevent nonhuman primates from being infected with the monkey form of HIV, new research shows. The results will inform a future human clinical trial evaluating leronlimab as a potential pre-exposure prophylaxis, or PrEP, therapy to prevent human infection from the virus that causes AIDS. |
| Plants get a faster start to their day than we think Posted: 07 Jun 2021 05:22 PM PDT To describe something as slow and boring we might say it's 'like watching grass grow', but scientists studying the early morning activity of plants have found they make a rapid start to their day - within minutes of dawn. |
| This forest has stayed wild for 5,000 years -- the soil shows it Posted: 07 Jun 2021 01:12 PM PDT Parts of the Amazon have been cultivated by Indigenous peoples for thousands of years, and mere centuries ago were the sites of cities and farmland, but other parts are 'untouched.' By examining microscopic bits of plant remains and charcoal in the soil, scientists learned that the Putumayo region of Peru's plant life hasn't changed much in 5,000 years, meaning that the people who have lived there found a long-term way to co-exist with nature. |
| Arctic rotifer lives after 24,000 years in a frozen state Posted: 07 Jun 2021 01:11 PM PDT Bdelloid rotifers are multicellular animals so small you need a microscope to see them. Despite their size, they're known for being tough, capable of surviving through drying, freezing, starvation, and low oxygen. Now, researchers have found that not only can they withstand being frozen, but they can also persist for at least 24,000 years in the Siberian permafrost and survive. |
| Physicists report definitive evidence how auroras are created Posted: 07 Jun 2021 01:11 PM PDT Physicistsreport definitive evidence of how auroras are created. In experiments, the physicists demonstrated the physical mechanisms for the acceleration of electrons by Alfven waves under conditions corresponding to Earth's auroral magnetosphere. |
| Conserving coastal seaweed: A must have for migrating sea birds Posted: 07 Jun 2021 01:11 PM PDT Ecologists are urging coastal communities to embrace all that the season brings, including the sometimes-unwelcome deposits of brown seaweed that can accumulate on the southern shores. |
| Antarctica: How have temperatures varied since the last glacial period? Posted: 07 Jun 2021 01:11 PM PDT Antarctica has experienced significant temperature changes, especially since the last glacial period. An international collaboration has now challenged previously accepted estimates of these variations, using new measurements. Their study highlights differences in behavior between East and West Antarctica, connected in particular to differing variations in their altitude. |
| Researchers find toxin from maple tree in cow's milk Posted: 07 Jun 2021 01:11 PM PDT Cows can pass on the hypoglycin A toxin through their milk, a study shows. The substance can cause severe symptoms in humans and animals. Small amounts of the toxin were detected in the raw milk of cows that grazed in a pasture exposed to sycamore maple. The team calls for further investigations to realistically assess the potential dangers. |
| Posted: 07 Jun 2021 01:10 PM PDT Ancient chickens lived significantly longer than their modern equivalents because they were seen as sacred -- not food -- archaeologists have found. |
| Climate warming to increase carbon loss in Canadian peatland by 103 per cent Posted: 07 Jun 2021 01:10 PM PDT Carbon loss in Canadian peatland is projected to increase by 103 per cent under a high emission scenario, according to new research. |
| Carbon dioxide sensors in two urban areas registered big drop in emissions during COVID-19 pandemic Posted: 07 Jun 2021 01:10 PM PDT Carbon dioxide emissions in Los Angeles and the Washington DC/Baltimore regions fell roughly 33 percent in April of 2020 compared with previous years, as roads emptied and economic activity slowed due to the COVID-19 pandemic, according to a new study. But while the emissions reductions are significant, the method that scientists used to measure them may have the greater long-term impact. |
| School lesson gone wrong leads to new, bigger megalodon size estimate Posted: 07 Jun 2021 01:10 PM PDT A more reliable way of estimating the size of megalodon shows the extinct shark may have been bigger than previously thought, measuring up to 65 feet, nearly the length of two school buses. |
| Lead halide perovskites -- a horse of a different color Posted: 07 Jun 2021 01:10 PM PDT Researchers have developed a novel spectroscopic technique for the study of charge carrier dynamics in lead halide perovskites. |
| Infrared imaging leaves invasive pythons nowhere to hide Posted: 07 Jun 2021 01:10 PM PDT Researchers report that a near infrared camera helped people detect Burmese pythons at distances up to 1.3 times farther away than was possible using a traditional visible-wavelength camera. |
| Puerto Rico is prone to more flooding than the island is prepared to handle Posted: 07 Jun 2021 01:10 PM PDT Puerto Rico is not ready for another hurricane season, let alone the effects of climate change, according to a new study that shows the island's outstanding capacity to produce record-breaking floods and trigger a large number of landslides. |
| African great apes to suffer massive range loss in next 30 years Posted: 07 Jun 2021 01:10 PM PDT A new study predicts massive range declines of Africa's great apes -- gorillas, chimpanzees and bonobos -- due to the impacts of climate change, land-use changes and human population growth. |
| Trained viruses prove more effective at fighting antibiotic resistance Posted: 07 Jun 2021 01:09 PM PDT Research reveals that viruses known as bacteriophages that undergo special evolutionary training increase their capacity to subdue bacteria.
