| How an enriched environment fires up our synapses Posted: 20 Oct 2021 11:00 AM PDT Processing of sensory impressions and information depends very much on how the synapses in our brain work. A team has now shown how lipid and protein regulation impact brain's processing of a beautiful and stimulating environment. The lipids located in the membranes of the synapses are central to signal transmission, the researchers report. |
| Scientists enable a blind woman to see simple shapes Posted: 20 Oct 2021 11:00 AM PDT Newly published research details how a team of scientists successfully created a form of artificial vision for a blind woman using a brain implant. |
| Study of DNA repair boosts prospects for gene editing technology Posted: 20 Oct 2021 10:59 AM PDT Researchers have developed a new method to profile the activity of cellular genes involved in correcting DNA damage, and applied this method to pave the way for dramatic improvements to genome editing technologies. |
| Hit the sleep ‘sweet spot’ to keep brain sharp Posted: 20 Oct 2021 10:59 AM PDT Older adults who sleep short or long experienced greater cognitive decline than those who sleep a moderate amount, even when the effects of early Alzheimer's disease were taken into account, according to a new study. |
| Male-female differences in heart disease could start before birth Posted: 20 Oct 2021 10:58 AM PDT New research suggests that male-female differences in protein expression occur immediately after embryonic cells become heart cells called cardiomyocytes. This is the earliest stage of heart development, well before the embryo is exposed to sex hormones. |
| In your face: Children’s expressions tell the story of poor sleep Posted: 19 Oct 2021 07:32 PM PDT When children are overtired, their facial expressions can forecast social problems years later, according to a new report published by a psychologist. |
| Scientists develop sperm cells from primate stem cells Posted: 19 Oct 2021 07:32 PM PDT A new study shows that functional sperm cells can be made in a dish using primate embryonic stem cells. |
| Brain activation in sleeping toddlers shows memory for words Posted: 19 Oct 2021 07:32 PM PDT Very young children learn words at a tremendous rate. Now researchers have seen how specific brain regions activate as two-year-olds remember newly learned words -- while the children were sleeping. |
| Cat bacteria treats mouse skin infection, may help you and your pets as well Posted: 19 Oct 2021 09:35 AM PDT Researchers identify a strain of bacteria on healthy cats that produces antibiotics against severe skin infections. The findings may soon lead to new bacteriotherapies for humans and their pets, wherein cat bacteria is applied via topical cream or spray. |
| Viral infections could promote neurodegeneration Posted: 19 Oct 2021 09:01 AM PDT Some viral diseases could possibly contribute to neurodegeneration. Researchers found that certain viral molecules facilitated intercellular spreading of protein aggregates that are hallmarks of brain diseases like Alzheimer's. These findings may provide clues how acute or chronic viral infections could contribute to neurodegeneration. |
