New surgery may enable better control of prosthetic limbs Posted: 15 Feb 2021 01:04 PM PST Researchers and surgeons have devised a new type of amputation surgery that can help amputees better control their residual muscles and receive sensory feedback. This restored sense of proprioception should translate to better control of prosthetic limbs, as well as reduction of limb pain, the researchers say.

Light used to detect quantum information stored in 100,000 nuclear quantum bits Posted: 15 Feb 2021 10:12 AM PST Researchers have found a way to use light and a single electron to communicate with a cloud of quantum bits and sense their behavior, making it possible to detect a single quantum bit in a dense cloud.

New skin patch brings us closer to wearable, all-in-one health monitor Posted: 15 Feb 2021 10:12 AM PST Engineers have developed a soft, stretchy skin patch that can be worn on the neck to continuously track blood pressure and heart rate while measuring the wearer's levels of glucose as well as lactate, alcohol or caffeine. It is the first wearable device that monitors cardiovascular signals and multiple biochemical levels in the human body at the same time.

Tropical paper wasps babysit for neighbors Posted: 15 Feb 2021 10:12 AM PST Wasps provide crucial support to their extended families by babysitting at neighboring nests, according to new research.

New immunotherapy target discovered for malignant brain tumors Posted: 15 Feb 2021 08:03 AM PST Scientists say they have discovered a potential new target for immunotherapy of malignant brain tumors, which so far have resisted the ground-breaking cancer treatment based on harnessing the body's immune system. The discovery emerged from laboratory experiments and has no immediate implications for treating patients.

Cheap, potent pathway to pandemic therapeutics Posted: 15 Feb 2021 08:03 AM PST By capitalizing on a convergence of chemical, biological and artificial intelligence advances, scientists have developed an unusually fast and efficient method for discovering tiny antibody fragments with big potential for development into therapeutics against deadly diseases.

Aspirin preferred to prevent blood clots in kids after heart surgery, study suggests Posted: 15 Feb 2021 06:24 AM PST Aspirin should be favoured over warfarin to prevent blood clotting in children who undergo a surgery that replumbs their hearts, according to a new study.

Neanderthals and Homo sapiens used identical Nubian technology Posted: 15 Feb 2021 06:24 AM PST New analysis of a fossil tooth and stone tools from Shukbah Cave reveals Neanderthals used stone tool technologies thought to have been unique to modern humans.

Higher elevation birds sport thicker down Posted: 15 Feb 2021 06:24 AM PST A new study examines feathers across 249 species of Himalayan songbirds, finding that birds at higher elevations have more of fluffy down than lower elevation birds. Finding such a clear pattern across many species underscores how important feathers are to birds' ability to adapt to their environments. Furthermore, finding that birds from colder environments tend to have more down may one day help predict which birds are vulnerable to climate change simply by studying feathers.

Invasive flies prefer untouched territory when laying eggs Posted: 15 Feb 2021 06:24 AM PST A recent study finds that the invasive spotted wing drosophila (Drosophila suzukii) prefers to lay its eggs in places that no other spotted wing flies have visited. The finding raises questions about how the flies can tell whether a piece of fruit is virgin territory - and what that might mean for pest control.

The comet that killed the dinosaurs Posted: 15 Feb 2021 06:24 AM PST Scientists have put forth a new theory that could explain the origin and journey of the comet that killed the Chicxulub impactor and others like it.

Membrane building blocks play decisive role in controlling cell growth Posted: 15 Feb 2021 06:24 AM PST Lipids are the building blocks of a cell's envelope - the cell membrane. In addition to their structural function, some lipids also play a regulatory role and decisively influence cell growth. The impact of the lipids depends on how they are distributed over the plasma membrane.

Managing crab and lobster catches could offer long-term benefits Posted: 15 Feb 2021 06:24 AM PST A study has found that managing the density of crab and lobster pots at an optimum level increases the quality of catch, benefits the marine environment and makes the industry more sustainable in the long term.

Capuchin monkey genome reveals clues to its long life and large brain Posted: 15 Feb 2021 06:24 AM PST Scientists have sequenced the genome of a capuchin monkey for the first time, uncovering new genetic clues about the evolution of their long lifespan and large brains.

Commuters are inhaling unacceptably high levels of carcinogens Posted: 15 Feb 2021 06:24 AM PST New research shows the average commuter in California is breathing unsustainably high levels of benzene and formaldehyde, two Prop. 65-listed, carcinogenic chemicals.

More trees do not always create a cooler planet, study shows Posted: 12 Feb 2021 11:55 AM PST New research by an environmental scientist reveals that deforestation in the U.S. does not always cause planetary warming, as is commonly assumed; instead, in some places, it actually cools the planet.
