| Researchers uncover how the human brain separates, stores, and retrieves memories Posted: 07 Mar 2022 08:31 AM PST Researchers have identified two types of cells in our brains that are involved in organizing discrete memories based on when they occurred. This finding improves our understanding of how the human brain forms memories and could have implications in memory disorders such as Alzheimer's disease. |
| Novel antiviral drug combinations demonstrate COVID-19 therapeutic potential Posted: 07 Mar 2022 08:30 AM PST Researchers demonstrate that combinations of antiviral drugs inhibiting both polymerase and exonuclease reduce SARS-CoV-2 replication 10 times more than polymerase inhibitors alone. |
| How does the brain make memories? Posted: 07 Mar 2022 08:30 AM PST Researchers have discovered two types of brain cells that play a key role in dividing continuous human experience into distinct segments that can be recalled later. The discovery provides new promise as a path toward development of novel treatments for memory disorders such as dementia and Alzheimer's disease. |
| Cellular rejuvenation therapy safely reverses signs of aging in mice Posted: 07 Mar 2022 08:30 AM PST Age may be just a number, but it's a number that often carries unwanted side effects, from brittle bones and weaker muscles to increased risks of cardiovascular disease and cancer. Now, scientists have shown that they can safely and effectively reverse the aging process in middle-aged and elderly mice by partially resetting their cells to more youthful states. |
| New early signs of Parkinson’s uncovered in diverse study Posted: 07 Mar 2022 08:30 AM PST Hearing loss and epilepsy are early features of Parkinson's, according to pioneering new research. |
| Genetic study gives extensive insights into severe COVID-19 Posted: 07 Mar 2022 08:30 AM PST The world's largest study of the genetics of critical COVID-19, involving more than 57,000 people, has revealed fresh details about some of the biological mechanisms behind the severe form of the disease. |
| Lensless camera captures cellular-level, 3D details in living tissue Posted: 07 Mar 2022 08:29 AM PST The lensless Bio-FlatScope is a small, inexpensive camera to monitor biological activity that can't be captured by conventional instruments. The device could eventually be used to look for signs of cancer or sepsis or become a valuable endoscopy tool. |
| Is it working? Scientists say gene variant indicates effectiveness of immunotherapy for allergies Posted: 07 Mar 2022 06:17 AM PST Although sublingual immunotherapy (SLIT) has become an effective treatment option for many allergies, about 20-30 percent of patients don't respond to SLIT for Japanese cedar pollinosis -- a highly common disease. In a recent study, scientists reported that a specific variant of the HLA-DPB1 gene is associated with poor response to this treatment, highlighting the potential of this and similar genes as relevant biomarkers in clinical practice for predicting one's responsiveness to allergen immunotherapy. |
| People with heart defects may be at greater risk for severe COVID-19 illness Posted: 07 Mar 2022 05:23 AM PST People with congenital heart defects who were hospitalized with COVID-19 were up to twice as likely to suffer severe illness or death from the virus compared to people who were not born with a heart defect, according to a new study. People with a heart defect plus another underlying medical condition, including heart failure, pulmonary hypertension, Down syndrome, diabetes or obesity, were among those most at risk of having severe COVID-19 illness. |
| Pig grunts reveal their emotions Posted: 07 Mar 2022 05:23 AM PST We can now decode pigs' emotions. Using thousands of acoustic recordings gathered throughout the lives of pigs, from their births to deaths, an international team of researchers has translated pig grunts into the emotions they appear to express. |
| Higher risk of temperature-related death if global warming exceeds 2°C Posted: 07 Mar 2022 05:23 AM PST The death rate linked to extreme temperatures will increase significantly under global warming of 2°C, finds a new report. Temperature-related mortality -- where a death is directly linked to climate temperature -- in England and Wales during the hottest days of the year will increase by 42% under a warming scenario of 2°C from pre-industrial levels. This means an increase from present-day levels of around 117 deaths per day, averaged over the 10 hottest days of the year, to around 166 deaths per day. The findings underline the importance of keeping global warming levels to below 2°C. |
