| Risky driving behaviors increase as common sleep disorder worsens Posted: 20 Apr 2022 02:05 PM PDT Up to half of older adults may have sleep apnea, a condition in which breathing and sleep are briefly interrupted many times a night. A new study shows that this chronic tiredness can have serious implications for road safety. |

| Widespread brain receptor hides surprising mechanism of action Posted: 20 Apr 2022 02:05 PM PDT One of the most important molecules in the brain doesn't work quite the way scientists thought it did, according to new work. |
| Women's earnings drop after childbirth, study finds Posted: 20 Apr 2022 12:16 PM PDT When U.S. couples have their first child, mothers' earnings still drop substantially relative to fathers', and new research demonstrates the stubborn, decades-old pattern isn't changing despite broad increases in other aspects of gender equality. |
| Opioid-related deaths affecting more younger adults, study finds Posted: 20 Apr 2022 12:16 PM PDT From 2003 through 2020, as opioid-related mortality in Ontario, Canada increased five-fold, the age distribution also shifted downward -- with rates now peaking for people in their mid-30s -- according to a new study. |
| Antidepressants are not associated with improved quality of life in the long run, study finds Posted: 20 Apr 2022 12:15 PM PDT Over time, using antidepressants is not associated with significantly better health-related quality of life, compared to people with depression who do not take the drugs, according to a new study. |
| Got food cravings? What's living in your gut may be responsible Posted: 20 Apr 2022 12:15 PM PDT New research on mice shows for the first time that the microbes in animals' guts influence what they choose to eat, making substances that prompt cravings for different kinds of foods. |
| Portable MRIs almost as effective as standard MRIs in detecting strokes Posted: 20 Apr 2022 12:13 PM PDT Portable MRI machines, an emerging technology that makes medical imaging accessible even in remote locations, detected ischemic strokes, or strokes caused by clotting, in 90% of patients scanned, according to a new study. |
| Fewer smartphones, more well-being Posted: 20 Apr 2022 10:35 AM PDT How much digital detox is necessary to live a better life? The good news is that we don't have to waive them completely. |
| In the race to solve Alzheimer's disease, scientists find more needles in the haystack Posted: 20 Apr 2022 09:49 AM PDT The International Genomics of Alzheimer's Project (IGAP) analyzed millions of genetic variants to come up with the latest listing of 75 variations associated with Alzheimer's disease. |
| Whole-brain preclinical study illuminates how epileptic seizures originate Posted: 20 Apr 2022 09:20 AM PDT New evidence from a zebrafish model of epilepsy may help resolve a debate into how seizures originate, according to investigators. The findings may also be useful in the discovery and development of future epilepsy drugs. |
| How do our eyes stay focused on what we reach for? Posted: 20 Apr 2022 08:30 AM PDT Keeping our eyes focused on what we reach for, whether it be an item at the grocery store or a ground ball on the baseball field, may appear seamless, but, in fact, is due to a complex neurological process involving intricate timing and coordination. Researchers now shed additional light on the machinations that ensure we don't look away from where we are reaching. |
| Genetic changes differed, increased in people with Alzheimer's disease Posted: 20 Apr 2022 08:29 AM PDT Researchers found that changes accumulated in the brain cells of patients with Alzheimer's disease at a faster rate, potentially explaining why brain cells die and revealing new pathways to target for treatment. |
| Fetal exposure to meds may affect infants' brain development Posted: 20 Apr 2022 06:22 AM PDT A new study demonstrates that in utero exposure to mother's antiepileptic or antidepressant medication may affect development of the newborn brain networks. In the study, novel mathematical methods were developed to allow future research on how commonly used drugs or other environmental conditions affect the newborn brain. |
| Unexpected protein could play role in common brain disorder Posted: 20 Apr 2022 06:21 AM PDT Scientists report that amyloid fibrils found in people with frontotemporal degeneration contain the little-known protein TMEM106B. |
| Posted: 20 Apr 2022 06:21 AM PDT Scientists used pharmacogenetic techniques to identify a dedicated neural circuit comprising the central nucleus of the amygdala and the bed nucleus of the stria terminalis. The activation of this circuit in the first few hours of sepsis induces anxious behavior two weeks after the infection has cleared. This behavior observed in mice mimics the post-traumatic stress disorder observed in patients recovering from sepsis. |
| Windows to the soul: Pupils reveal 'aphantasia' -- the absence of visual imagination Posted: 20 Apr 2022 06:21 AM PDT Picture this, if you will: Aphantasia can be detected with an eye-opening look into our pupils. |
| Enzyme prevents brain activity from getting out of control Posted: 20 Apr 2022 06:21 AM PDT The brain has the ability to modify the contacts between neurons. Among other things, that is how it prevents brain activity from getting out of control. Researchers have now identified a mechanism that plays an important role in this. |
| Impact of family background on children's education unchanged in a century, research reveals Posted: 20 Apr 2022 06:21 AM PDT A study which looked at data from 92,000 individuals born between 1921 and 2011, has revealed the achievement gap between children from impoverished family backgrounds and their more privileged peers has remained stagnant in the UK. |
| Disasters could disrupt care for opioid use disorder in most vulnerable communities Posted: 19 Apr 2022 11:07 AM PDT The COVID-19 pandemic has spiked the overdose death rate from opioid use. For people who rely on medications (buprenorphine, methadone, and extended-release naltrexone) to treat opioid use disorders, the pandemic and such natural disasters as tornados, hurricanes, and wildfires can disrupt access to medications. And new research finds that the location of medication treatment services makes treatment interruption likely where those disruptions exist. |
| COVID-19 pneumonia increases dementia risk Posted: 19 Apr 2022 09:41 AM PDT A new study shows patients hospitalized with COVID-19 pneumonia have a higher risk of developing dementia than those with other types of pneumonia. |
| Posted: 18 Apr 2022 06:40 AM PDT Researchers developed a biomaterial using stem cells aiming to reverse a condition called intervertebral disk (IVD) degeneration, which is associated with back pain and certain spinal issues. The stem cells were induced into chondrocytes -- cells producing collagen that supports cartilage tissue. Implanting this biomaterial into a rat model of IVD degeneration brought the spinal mechanical properties back to control levels. This could be crucial for regenerative medicine to reverse this painful back problem. |
