| Alcohol consumption is affected by a protein linked to the circadian rhythm Posted: 11 Jan 2022 04:30 PM PST Researchers announce that the presence of the Bmal1 gene in the striatum affects alcohol consumption in both male and female mice in a sexually dimorphic manner. Male mice without the protein consumed more alcohol than those that had it, while female mice without the protein consumed less than females with it. |
| Using only 100 atoms, electric fields can be detected and changed Posted: 11 Jan 2022 04:30 PM PST The body is full of electrical signals. Researchers have now created a new nanomaterial that is capable of both detecting and modulating the electric field. This new material can be used in vitro studies for 'reading and writing' the electric field without damaging nearby cells and tissue. In addition, researchers can use this material to conduct in vitro studies to understand how neurons transmit signals but also to understand how to potentially shut off errant neurons. This may provide critical insights on neurodegeneration. |
| Brain-based method to determine impairment from cannabis intoxication Posted: 11 Jan 2022 12:36 PM PST A new study shows that imaging of brain activity with functional near-infrared spectroscopy might offer a more accurate and reliable way to distinguish impairment from cannabis intoxication. |
| Older adult opioid overdose death rates on the rise Posted: 11 Jan 2022 08:20 AM PST A new study that analyzed 20 years of fatal opioid overdose data in adults 55 and older found that between 1999 and 2019, opioid-related overdose deaths increased exponentially in U.S. adults ages 55 and older, from 518 deaths in 1999 to 10,292 deaths in 2019: a 1,886% increase. |
