| Long-term pain after knee surgery reduced, new treatment has shown Posted: 29 Jan 2022 05:42 AM PST With one in five people experiencing ongoing pain long after knee replacement surgery, new research has shown a way to help reduce people's continuing pain that could also save time and money too. |
| Peruvian gold rush turns pristine rainforests into heavily polluted mercury sinks Posted: 28 Jan 2022 05:57 AM PST Illegal gold mining in the Peruvian Amazon is causing exceptionally high levels of atmospheric mercury pollution in a nearby patch of pristine rainforest. One stand of old-growth pristine forest had the highest levels of mercury ever recorded, rivaling industrial areas where mercury is mined. Birds from this area have up to twelve times more mercury in their system than birds from less polluted areas, a level of poisoning that should harm their reproduction. |
| Infant deaths from RSV are much higher than previously known Posted: 27 Jan 2022 02:26 PM PST A new study has found that the true burden of RSV infant mortality is substantially higher than what was previously believed. The study used systematic surveillance to measure the presence of RSV among infants who died in medical facilities or in the community and found that the virus was present in 7 to 9 percent of infants under 6 months old and was primarily concentrated in infants under 3 months old. Two-thirds of these deaths occurred in the community -- i.e., among infants who never received medical care in a hospital and were overlooked in previous facility-based surveillance. |
| Crowding, climate change, and the case for distancing among trees Posted: 27 Jan 2022 02:26 PM PST In the age of large-scale fires, forest-wide beetle invasions, and frequent drought, maintaining 'ideal' historical conditions is becoming increasingly unrealistic. Novel conditions require different strategies; lower crowding for trees can increase chances of survival after fire. Results from two long-term studies show that chances for long-term tree survival increased when trees had more space, by reducing competition and helping trees recover from fire more quickly. |
| Gene regulation: How long do proteins bind? Posted: 27 Jan 2022 11:15 AM PST Researchers show how a DNA-binding protein can search the entire genome for its target sequence without getting held up on the way. The result contradicts our current understanding of gene regulation - the genetic code affects how often the proteins bind, but not for how long. |
