| Babies can tell who has close relationships based on one clue: Saliva Posted: 20 Jan 2022 11:07 AM PST Neuroscientists have identified a specific signal that young children and even babies can use to determine whether two people have a strong relationship and a mutual obligation to help each other: whether those two people kiss, share food, or have other interactions that involve sharing saliva. |
| Posted: 20 Jan 2022 11:07 AM PST An artificial pancreas is helping protect very young children with type 1 diabetes at a particularly vulnerable time of their lives. A study published today found that it is both safe to use and more effective at managing their blood sugar levels than current technology. |
| COVID-19 vaccines do not cause infertility, study finds Posted: 20 Jan 2022 10:51 AM PST New findings indicate that COVID-19 vaccination does not impair fertility, but males who become infected by the coronavirus may experience short-term reduced fertility. |
| You can feel this acid when you work out. Now it may increase knowledge of cancer medicine Posted: 20 Jan 2022 10:51 AM PST New research shows that specific enzymes can remove lactic acid marks. This finding may increase our understanding of cancer medicine and how physical exercise, among other things, can affect human epigenetics. |
| An all-in-one approach to diabetes treatment Posted: 20 Jan 2022 10:51 AM PST A team of researchers has come up with a new approach to streamline the process that people with diabetes use to estimate the carbohydrate content of a meal, draw blood to measure current blood glucose levels, and calculate and deliver the correct insulin dose. |
| Mapping dementia-linked protein interactions yields potential new treatment targets Posted: 20 Jan 2022 10:51 AM PST By mapping all the protein interactions of a dementia-linked protein in the brain called Tau, a team of investigators has created a road map for identifying potential new treatment targets for Alzheimer's disease and related dementia. |
| The cellular response that protects pigs from COVID-19 Posted: 20 Jan 2022 09:54 AM PST Studies since the start of the pandemic have noted that pigs exposed to the coronavirus don't show clinical signs of disease nor do they transmit the virus to other animals. Scientists have uncovered important clues that shed light on why pigs don't get sick, and the discovery could lead to better treatments for COVID-19 in humans. |
| Cancer treatment may inhibit immune response to COVID-19 vaccination Posted: 20 Jan 2022 09:54 AM PST A study has found that patients with cancer who receive chemotherapy -- and some targeted therapies, such as CDK4/6 inhibitors and therapies targeted at B cells -- may mount an inadequate immune response to COVID-19 vaccination. |
| Social isolation among older adults linked to having fewer teeth Posted: 20 Jan 2022 09:54 AM PST Older adults who are socially isolated are more likely to have missing teeth--and to lose their teeth more quickly over time--than those with more social interaction, according to a new study of Chinese older adults. |
| Drug mimics beneficial effects of fasting in mice Posted: 20 Jan 2022 09:54 AM PST An investigational cancer drug that starves tumors of their energy supply also shows evidence of improving whole body metabolism, leading to improved weight control, according to a new study in mice. |
| Research in mice identifies neurons that control locomotion Posted: 20 Jan 2022 09:54 AM PST For more than a century, scientists have known that while the commands that initiate movement come from the brain, the neurons that control locomotion once movement is underway reside within the spinal cord. Researchers now report that, in mice, they have identified one particular type of neuron that is both necessary and sufficient for regulating this type of movement. These neurons are called ventral spinocerebellar tract neurons (VSCTs). |
| Old neurons can block neurogenesis in mice Posted: 20 Jan 2022 09:54 AM PST Destroying senescent cells in the aging stem cell niche enhances hippocampal neurogenesis and cognitive function in mice, researchers report. |
| Meta-analysis may help guide treatment planning for patients with high-risk prostate cancer Posted: 20 Jan 2022 09:53 AM PST Results of a large study could help guide treatment planning for patients with high-risk prostate cancer. |
| Supplement appears to boost muscle, mitochondria health Posted: 20 Jan 2022 09:53 AM PST An oral supplement intended to stimulate a natural body process appears to promote muscle endurance and mitochondrial health in humans. New research suggests that the supplement, urolithin A, may help improve or prolong muscle activity in people who are aging or who have diseases that make exercise difficult. |
| Posted: 20 Jan 2022 07:34 AM PST A team of researchers has identified a neural network which is responsible for generating tic disorders. Targeting of this network via deep brain stimulation delivered by a pacemaker-like device has resulted in the alleviation of symptoms in people with Tourette syndrome. The researchers' findings could serve as a basis for improving the treatment of people with severe tic disorders. |
| Posted: 20 Jan 2022 07:34 AM PST Faulty DNA damage repair can lead to many types of cancer, neurodegenerative diseases, and other serious disorders. Investigators have developed high-throughput microscopy and machine learning systems that can identify and classify DNA repair factors. The investigators have identified nine previously unknown factors involved in the process of cellular DNA repair. |
| Mediterranean diet associated with a lower risk of mortality in older adults Posted: 20 Jan 2022 07:34 AM PST A greater adherence to the Mediterranean diet which had been assessed through an index made with biomarkers during a 20-year scientific monitoring is associated with a lower mortality in adults over 65. |
| Researchers simulate SARS-COV-2 transmission and infection on airline flights Posted: 20 Jan 2022 06:09 AM PST A new study simulated the transmission of SARS-CoV-2, the virus that causes COVID-19, on a flight from London to Hanoi and on another flight from Singapore to Hangzhou. |
| COVID-19 vaccine booster provides good antibody protection against Omicron, researchers find Posted: 19 Jan 2022 04:42 PM PST A third 'booster' dose of COVID-19 vaccine successfully raises antibody levels that neutralize the Omicron variant, according to laboratory findings. |
| COVID-19: Small study found no evidence of transmitting virus through breastfeeding Posted: 18 Jan 2022 05:35 PM PST There is no evidence of recently infected mothers transmitting infectious SARS-CoV-2 through breastmilk to their baby, a new study reports. |
