Study Details How General Anesthetics And ‘Benzos’ Act on Receptors in The Brain
As you drift into unconsciousness before a surgery, general anesthetic drugs flowing through your blood are putting you to sleep by binding mainly to a protein in the brain called the ɣ-aminobutyric acid type A (GABAA) receptor. Now UT Southwestern scientists have shown exactly how anesthetics attach to the GABAA receptor and alter its three-dimensional structure, and how the brain can tell the difference between anesthetics and the psychoactive drugs known as benzodiazepines – which also bind to the GABAA receptor. The findings were published online today in the journal Nature.
New connections reveal how cancer evades the immune system

Adjusting Jailed Women’s Beliefs about Their Friends’ Substance Use May Help Reduce Their Drinking and Risk of Reoffending
Brief interventions can potentially reduce incarcerated women’s alcohol use when they leave jail, according to a new study. Researchers explored jailed women’s impressions of how their friends and acquaintances drank and used drugs (“social norms”). Research shows that people who perceive their friends drinking heavily are more likely to drink heavily themselves, while individuals who realize that their friends in fact drink moderately tend to reduce their own alcohol use. Often, perceptions of substance use in a social network are skewed. Past research on this phenomenon has focused on college students, with slight attention to people involved in the criminal justice system. Two in three incarcerated adults have a substance use disorder — compared to one in ten of the general population — and consequently may regard their own alcohol and drug use as typical. Substance use is strongly implicated in criminal justice involvement and reoffending, especially for women. This study in Alcoho

Guilt by Dissociation: Study Sheds Light on Serotonin in Autism
A study on serotonin, a mood-regulating molecule in the brain that regulates many brain synapses, is helping to unravel the puzzle surrounding its role in autism. The activity and regulation of the serotonin transporter (SERT), protein is critically dependent on a number of other proteins that tell the protein where to locate on nerve cells and how to act. Shifts in the transporter’s activity can significantly impact the ability of serotonin to act in the brain.

Food insecurity and schools during the pandemic
The coronavirus pandemic has brought a number of challenges to schools, which were forced to close in the spring to help slow the spread of infection. One major challenge for schools was ensuring that students’ nutritional supplementation needs were met when they were not attending school in person.As schools across the country begin to welcome students back in person or for virtual learning, equity must be at the forefront of decisions pertaining to school emergency food services, finds a new study from the Brown School at Washington University in St. Louis.
Face Shield or Face Mask to Stop the Spread of COVID-19?
If CDC guidelines aren’t enough to convince you that face shields alone shouldn’t be used to stop the spread of COVID-19, then maybe a new visualization study will. Researchers simulated coughing and sneezing from a mannequin’s mouth using a laser light to visualize droplets expelled. They tested a plastic face shield and found that they block the initial forward motion of the exhaled jet, however, aerosolized droplets are able to move around the visor with relative ease.
Decorating Windows for Optimal Sound Transmission
Glass windows typically offer some amount of sound proofing, sometimes unintentionally. In general, ventilation is required to achieve large sound transmission. But some applications — like gas explosion studies — require a transparent partition that allows for acoustic propagation without the presence of airflow. In those cases, ventilation is not allowed. In Applied Physics Letters, researchers discuss a layered glass material they developed that allows for efficient sound transmission with no air ventilation.
Detecting Small Amounts of Virus in Early Infections
Diagnostic devices that are used at home or in doctors’ offices are often not sensitive enough to detect small amounts of a virus that might be present in samples from asymptomatic patients, which can occur in early stage COVID-19. In Biomicrofluidics, scientists report a membrane-based invention that can concentrate the virus content of a sample of urine or saliva, allowing it to be detected.
