| New muscle layer discovered on the jaw Posted: 20 Dec 2021 09:07 AM PST Human anatomy still has a few surprises in store for us: researchers have discovered a previously overlooked section of our jaw muscles and described this layer in detail for the first time. |
| Consciousness in humans, animals and artificial intelligence Posted: 20 Dec 2021 09:07 AM PST A new theory of consciousness provides experimental access to the study of this phenomenon. Not just in humans. |
| School uniforms don't improve child behavior, study finds Posted: 20 Dec 2021 09:07 AM PST Despite the belief of many parents and teachers, school uniforms don't seem to have any effect on young students' behavior or attendance overall, a new U.S. national study found. |
| People with high-risk prediabetes benefit from intensive lifestyle intervention Posted: 20 Dec 2021 09:06 AM PST Intensive lifestyle intervention with plenty of exercise helps people with prediabetes improve their blood glucose levels over a period of years and thus delay or even prevent type 2 diabetes. In particular, individuals with prediabetes at highest risk benefited from intensive lifestyle intervention. |
| Scientists create mind-blowing tool to 'see' millions of brain cell connections in mice Posted: 20 Dec 2021 09:06 AM PST To solve the mysteries of how learning and memory occur, scientists have created a system to track millions of connections among brain cells in mice -- all at the same time -- when the animals' whiskers are tweaked, an indicator for learning. |
| How regular exercise can protect against fatty liver associated diseases Posted: 20 Dec 2021 09:06 AM PST Exercise not only trains the muscles but can also prevent the development of fatty liver. A new study shows which molecular adaptations, in particular of the liver mitochondria, can be observed in this process. |
| Shark antibody-like proteins neutralize COVID-19 virus, help prepare for future coronaviruses Posted: 17 Dec 2021 07:29 AM PST Small, unique antibody-like proteins known as VNARs -- derived from the immune systems of sharks -- can prevent the virus that causes COVID-19, its variants, and related coronaviruses from infecting human cells, according to a new study. |
| Posted: 17 Dec 2021 07:28 AM PST A proof-of-concept trial has identified a drug that may offer benefit some patients hospitalized with COVID-19 pneumonia. |
| Breakthrough infections generate 'super immunity' to COVID-19, study suggests Posted: 17 Dec 2021 07:25 AM PST Breakthrough infections greatly enhance immune response to variants of the virus that causes COVID-19, according to new research. The study is the first to use live SARS-CoV-2 variants to measure cross-neutralization of blood serum from breakthrough cases, portending an eventual 'end game' to the pandemic. |
| Mind-controlled robots now one step closer Posted: 16 Dec 2021 12:02 PM PST Researchers teamed up to develop a machine-learning program that can be connected to a human brain and used to command a robot. The program adjusts the robot's movements based on electrical signals from the brain. The hope is that with this invention, tetraplegic patients will be able to carry out more day-to-day activities on their own. |
| Posted: 16 Dec 2021 12:01 PM PST A study has found an association between air pollution and higher levels of deposition of beta-amyloid protein in the brain and of neurofilament light (NfL) in cerebrospinal fluid. |
| NIH scientists urge pursuit of universal coronavirus vaccine Posted: 16 Dec 2021 12:00 PM PST To counter future coronavirus outbreaks, the global scientific and medical research community should focus a major effort now on three goals: characterize the range of coronavirus genetic diversity in multiple animal species; better understand coronavirus disease pathogenesis in laboratory animal models and people; and apply this knowledge to the development of long-lasting, broadly protective coronavirus vaccines, experts argue in a new commentary. |
| Exploring genetics of SARS-CoV-2 and related viruses in animals around the world Posted: 16 Dec 2021 11:59 AM PST A genetic and geographic analysis of variants of SARS-CoV-2 -- the virus that causes COVID-19 -- and related viruses in humans and animals may provide evidence of interspecies transmission worldwide. |
| Choline transporter in the brain is necessary for tuning out unneeded information Posted: 16 Dec 2021 11:50 AM PST In habituation, an organism gets so used to a ubiquitous sight, smell, sensation or sound that it virtually disappears. Researchers have identified a transporter protein in the brain that plays a vital role in habituation. |
| Parkinson's disease mutation misdirects iron in the brain Posted: 16 Dec 2021 11:50 AM PST A common gene mutation for Parkinson's disease drives mislocalization of iron in activated microglia, according to a new study. The results may help explain the accumulation of toxic iron in affected brain areas in the disease and provide a basis for the development of therapies designed to correct the iron trafficking defect. |
