| Researchers develop ultra-thin 'computer on the bone' Posted: 19 Nov 2021 02:12 PM PST Researchers have developed an ultra-thin wireless device that grows to the surface of bone. Dubbed 'osseosurface electronics,' they could someday help physicians monitor bone health and healing over long periods. |
| Understanding how pathogenic fungi build their carbohydrate armor Posted: 19 Nov 2021 12:55 PM PST A research team revealed the molecular architecture of fungal cell walls and the structural responses to stresses, aiding the development of antifungal drugs targeting cell wall components. |
| Posted: 19 Nov 2021 12:54 PM PST It sounds like a party trick: scientists can now look at the brain activity of a tiny worm and tell you which chemical the animal smelled a few seconds before. But the findings of a new study are more than just a novelty; they help the scientists better understand how the brain functions and integrates information. |
| Scientists develop promising vaccine method against recurrent UTI Posted: 19 Nov 2021 05:51 AM PST Researchers are investigating the use of whole-cell vaccines to fight urinary tract infection (UTI), part of an effort to tackle the increasingly serious issue of antibiotic-resistant bacteria. |
| Scientists create insights into perhaps the most extreme state of matter produced on Earth Posted: 19 Nov 2021 05:51 AM PST Exotic laser-produced high-energy-density (HED) plasmas akin to those found in stars and nuclear explosions could provide insight into events throughout the universe. Physicists have discovered a new way to measure and understand these plasmas, among the most extreme states of matter ever produced on Earth. Improved understanding could provide benefits ranging from fine-tuning the high-density plasmas in inertial confinement fusion experiments to better understanding of processes throughout the universe. |
| Scientists solve 50-year-old mystery behind plant growth Posted: 18 Nov 2021 05:38 PM PST A team of researchers has demonstrated for the first time one way that a small molecule turns a single cell into something as large as a tree. For half a century, scientists have known that all plants depend on this molecule, auxin, to grow. Until now, they didn't understand exactly how auxin sets growth in motion. |
| Insulin in the brain influences dopamins levels Posted: 18 Nov 2021 05:38 PM PST In the human brain, the hormone insulin also acts on the most important neurotransmitter for the reward system, dopamine. Insulin lowers the dopamine level in a specific region of the brain (striatum) that regulates reward processes and cognitive functions, among other things. This interaction can be an important driver of the brain's regulation of glucose metabolism and eating behavior. |
| Resilience of vertebrate animals in rapid decline due to humanmade threats Posted: 18 Nov 2021 05:37 PM PST Global change is eroding life on earth at an unprecedented rate and scale. Species extinctions have accelerated over the last decades, with the concomitant loss of the functions and services they provide to human societies. |
| Antarctic ice-sheet destabilized within a decade Posted: 18 Nov 2021 05:37 PM PST After the natural warming that followed the last Ice Age, there were repeated periods when masses of icebergs broke off from Antarctica into the Southern Ocean. A new data-model study now shows that it took only a decade to initiate this tipping point in the climate system, and that ice mass loss then continued for many centuries. |
| Rivers play key role in destructive coastal flooding, new research shows Posted: 18 Nov 2021 05:37 PM PST Rising oceans get more attention in climate change discussions, but rivers are rising, too, according to new research by a University of South Carolina postdoctoral fellow. The research shows that rivers need more attention in policy management and disaster preparation, both at the coast and farther inland. |
| Speeding up the energy transition reduces climate risks Posted: 18 Nov 2021 05:37 PM PST The World Climate Conference in Glasgow has just ended, and the question is whether the goal of maximum global heating of 1.5°C can still be achieved. In a model calculation, researchers show how the energy transition could lead to the lowest possible cumulative emissions: Instead of slowly cutting back emissions, we should quickly push ahead with the conversion to solar energy and use fossil power plants at full capacity for one last time to do so. |
| Venom of cone snail could lead to future diabetes treatments Posted: 18 Nov 2021 05:37 PM PST Researchers have found that variants of this cone snail venom could offer future possibilities for developing new fast-acting drugs to help treat diabetics. |
| Posted: 18 Nov 2021 05:37 PM PST The most comprehensive survey conducted of elephant numbers in the Central African nation of Gabon since the late 1980s has found elephants occurring in higher numbers than previously thought. |
| Live long and prosper: Study examines genetic gems in Galápagos giant tortoise genomes Posted: 18 Nov 2021 05:37 PM PST Galápagos giant tortoises can weigh well over 300 pounds and often live over 100 years. So what's the secret to their evolutionary success? A new study concludes that compared with other turtles, these animals evolved to have extra copies of genes -- called duplications -- that may protect against the ravages of aging, including cancer. Laboratory tests on Galápagos giant tortoise cells corroborate the idea that the animals have developed such defenses. |
| Macrogrid study: Big value in connecting America’s eastern and western power grids Posted: 18 Nov 2021 05:37 PM PST A 'macrogrid' that increases the electricity moving between America's Eastern and Western interconnections, two of the biggest power grids on the planet, would more than pay for itself, according to new research. |
| New cell database paints fuller picture of muscle repair Posted: 18 Nov 2021 05:37 PM PST Biologists have struggled to study rare and transient muscle cells involved in the process, but engineers have lifted the curtain on these elusive dynamics with the launch of scMuscle, one of the largest single-cell databases of its kind. |
| Bubbling up: Previously hidden environmental impact of bursting bubbles exposed in new study Posted: 18 Nov 2021 05:36 PM PST Bubbles are common in nature and can form when ocean waves break and when raindrops impact surfaces. When bubbles burst, they send tiny jets of water and other materials into the air. A new study examines how the interplay between bubble surfaces and water that contains organic materials contributes to the transport of aerosolized organic materials -- some of which are linked to the spread of disease or contamination -- into the atmosphere. |
| Promising treatment for Alexander disease moves from rat model to human clinical trials Posted: 18 Nov 2021 05:35 PM PST Alexander disease is a progressive and rare neurological disorder with no cure or standard course of treatment. But a new study involving a rat model of the disease offers a potential treatment for the typically fatal condition. |
| Shaping a sustainable future for a common plastic Posted: 18 Nov 2021 05:34 PM PST Broad-based scientific team from government, academia and industry joins forces to identify new opportunities to reduce the environmental impact of polyurethane -- one of the most widely used but little recycled plastic materials. |
| How ultracold, superdense atoms become invisible Posted: 18 Nov 2021 05:34 PM PST Physicists have confirmed that as atoms are chilled and squeezed to extremes, their ability to scatter light is suppressed, making them less visible. The findings show the Pauli exclusion principle, or Pauli blocking, applies not just to electrons but also to atoms. |
| Extreme heat events jeopardize cardiovascular health, experts warn Posted: 18 Nov 2021 03:16 AM PST A consequence of global warming is a greater frequency and intensity of extreme heat events. This extreme heat is associated with a greater risk of adverse cardiovascular incidents, especially for adults with pre-existing cardiovascular diseases. |
