| California's trees are dying, and might not be coming back Posted: 14 Jul 2022 02:55 PM PDT The State of California is banking on its forests to help reduce planet-warming carbon dioxide in the atmosphere. But that element of the state's climate-change solution arsenal may be in jeopardy, as new research reports that trees in California's mountain ranges and open spaces are dying from wildfires and other pressures -- and fewer new trees are filling the void. |
| Geological activity can rapidly change deep microbial communities Posted: 14 Jul 2022 11:51 AM PDT New research reveals that, rather than being influenced only by environmental conditions, deep subsurface microbial communities can transform because of geological movements. The findings advance our understanding of subsurface microorganisms, which comprise up to half of all living material on the planet. |
| Scientists find primitive blueprint for embryo cell creation Posted: 14 Jul 2022 11:51 AM PDT A groundbreaking study has uncovered 14,000 unique sites in DNA that together form the most elementary blueprint for embryogenesis -- the creation of embryos. |
| Women already live longer. They can live better with an improved diet Posted: 14 Jul 2022 11:51 AM PDT Women tend to live longer than men but typically have higher rates of illness. Now, new research suggests these higher rates of illness can be improved by a better diet, one that is high in pigmented carotenoids such as yams, kale, spinach, watermelon, bell peppers, tomatoes, oranges and carrots. |
| Posted: 14 Jul 2022 11:51 AM PDT Theoretical physicists put Google's artificial intelligence AlphaFold to the test and find the most complex protein knots so far. |
| Trade deals and changing diets key influencers in securing nutrient rich food Posted: 14 Jul 2022 11:50 AM PDT Research shows future choices about trade, diet and climate change will be crucial in securing micronutrient food supplies for the UK. |
| Eco-friendly sound absorbers from seaweed Posted: 14 Jul 2022 11:50 AM PDT From airplanes to apartments, most spaces are now designed with sound-absorbing materials that help dampen the droning, echoing and murmuring sounds of everyday life. But most of the acoustic materials that can cancel out human voices, traffic and music are made from plastic foams that aren't easily recycled or degraded. Now, researchers have created a biodegradable seaweed-derived film that effectively absorbs sounds in this range. |
| Woodpeckers' heads act more like stiff hammers than safety helmets Posted: 14 Jul 2022 11:50 AM PDT Scientists had long wondered how woodpeckers can repeatedly pound their beaks against tree trunks without doing damage to their brains. This led to the notion that their skulls must act like shock-absorbing helmets. Now, researchers have refuted this notion, saying that their heads act more like stiff hammers. In fact, their calculations show that any shock absorbance would hinder the woodpeckers' pecking abilities. |
| North American birds not fully adjusting to changing climate Posted: 14 Jul 2022 11:50 AM PDT Some species of birds in North America have not fully adjusted their distributions in response to ongoing climate change. The places these birds live have become more decoupled from their optimal climate conditions, while other features of the environment become more constraining. This trend of climate decoupling is more pronounced for habitat specialists and for species declining in abundance. |
| Could eating fruit more often keep depression at bay? Posted: 14 Jul 2022 11:50 AM PDT A study surveyed 428 adults and looked at the relationship between their consumption of fruit, vegetables, sweet and savoury food snacks and their psychological health. The more often people ate fruit, the lower they scored for depression and the higher for mental wellbeing. |
| As globe warms, infected pines starve and disease-causing fungi thrive Posted: 14 Jul 2022 11:50 AM PDT The high heat and low water conditions produced by global warming weaken pine trees' resistance to disease by hindering their ability to mount an effective defense at the same time that pathogenic fungi in their tissues become more aggressive, new research suggests. |
| Individualized eating program helps dieters lose weight, keep it off Posted: 14 Jul 2022 11:49 AM PDT iDip, an individualized diet program, uses a unique visual tool that helps dieters choose foods that limit their daily calories while consuming adequate amounts of protein and fiber. Now in its third clinical trial, the program shows promise at helping people lose weight and keep it off. |
| A new peptide system for the targeted transport of molecules into living mammalian cells Posted: 14 Jul 2022 11:43 AM PDT Scientists have developed a novel peptide suitable for the targeted transport of molecules -- for example, active substances and dyes -- into the cells of mammals. |
| A brain network for social attraction Posted: 14 Jul 2022 07:30 AM PDT How does an animal's brain recognize other animals of its own kind? Scientists studying this process in young zebrafish have now discovered a neuronal circuit that mediates social attraction. This specialized pathway, which runs from the retina deep into the brain, enables zebrafish to detect and approach nearby conspecifics. |
| Action of drug compounds in tissue revealed by new technique Posted: 14 Jul 2022 06:51 AM PDT A new technique that can analyze how drug molecules bind to proteins in tissue samples could offer an improved route to drug discovery and development. |
| C. difficile drives some colorectal cancers, study suggests Posted: 14 Jul 2022 06:11 AM PDT Data suggest that Clostridioides difficile, or C. diff, a bacterial species well known for causing serious diarrheal infections, may also drive colorectal cancer. |
