| When the brain switches from hearing to listening Posted: 14 Dec 2021 10:51 AM PST What happens in the brain when simply hearing becomes listening? To answer this question, researchers have traced the neuronal fingerprint of the two types of sound processing in the mouse brain. |
| For children, young adults with recurrent AML, immunotherapy shows promise Posted: 14 Dec 2021 07:42 AM PST Researchers have shown, in a small clinical trial, that an immunotherapy harnessing pre-activated natural killer cells can help some children and young adults with recurrent AML and few other treatment options. |
| Personality traits predict performance differently across different jobs Posted: 13 Dec 2021 03:15 PM PST Researchers combined multiple meta-analyses of the five big personality traits and examined their effect on job performance. Researchers examined the effect of personality traits — conscientiousness, openness, extraversion, agreeableness, neuroticism — on performance in different occupations. |
| Learning and protecting itself: How the brain adapts Posted: 13 Dec 2021 03:15 PM PST If there is an injury to the central nervous system such as after a stroke, the brain needs to compensate for this by reorganising itself. To do this, a dense network of molecules between the nerve cells -- known as the extracellular matrix -- must loosen. This is the job of a wide variety of enzymes that ultimately regulate how plastic or how stable the brain is. Researchers studied what happens when certain enzymes are blocked in mice. Depending on whether the brain is healthy or diseased, the inhibition had opposite effects. |
| Common sleep disorder combo could be deadly Posted: 13 Dec 2021 09:18 AM PST People who suffer from both insomnia and obstructive sleep apnea are more likely to suffer from heart problems and are almost 50% more likely to die than those without either condition, say researchers, who advise people being tested for one of the disorders be tested for the other. |
| New hope for people living with a genetic cause of autism Posted: 13 Dec 2021 09:17 AM PST Researchers report they were able to ameliorate Fragile X syndrome symptoms after inserting the Fmr1 gene into the brains of very young transgenic mice that had been genetically engineered to lack this gene. When the researchers measured brain activity for signs of anxiety and hyperactivity in response to stimuli such as stresses and sounds, they found that the reactivation of the gene in these mice had led them to no longer show Fragile X syndrome symptoms. |
| Cannabis use could cause harmful drug interactions Posted: 13 Dec 2021 06:50 AM PST Using cannabis alongside other drugs may come with a significant risk of harmful drug-drug interactions, new research suggests. The researchers looked at cannabinoids--a group of substances found in the cannabis plant -- and their major metabolites found in cannabis users' blood and found that they interfere with two families of enzymes that help metabolize a wide range of drugs prescribed for a variety of conditions. As a result, either the drugs' positive effects might decrease or their negative effects might increase with too much building up in the body, causing unintended side effects such as toxicity or accidental overdose. While more research needs to be done, the authors said one early takeaway from these studies is that it's important to be careful when using cannabis with other prescription drugs. |
| Computer-, smartphone-based treatments effective at reducing symptoms of depression Posted: 13 Dec 2021 06:48 AM PST Computer- and smartphone-based treatments appear to be effective in reducing symptoms of depression, and while it remains unclear whether they are as effective as face-to-face psychotherapy, they offer a promising alternative to address the growing mental health needs spawned by the COVID-19 pandemic, according to new research. |
