| Social media use linked with depression, secondary trauma during COVID-19 Posted: 29 Sep 2020 12:21 PM PDT Can't stop checking social media for the latest COVID-19 health information? You might want to take a break, according to researchers who discovered that excessive use of social media for COVID-19 health information is related to both depression and secondary trauma.      |
| Many ventilation systems may increase risk of COVID-19 exposure, study suggests Posted: 29 Sep 2020 10:03 AM PDT Ventilation systems in many modern office buildings, which are designed to keep temperatures comfortable and increase energy efficiency, may increase the risk of exposure to the coronavirus, particularly during the coming winter, according to new research. |
| Wearable exosuit that lessens muscle fatigue could redesign the future of work Posted: 29 Sep 2020 09:35 AM PDT A new clothing-like exoskeleton can reduce back muscle fatigue and providing needed physical relief to material handlers, medical professionals and frontline workers. |
| Discovery enables adult skin to regenerate like a newborn's Posted: 29 Sep 2020 09:35 AM PDT A newly identified genetic factor allows adult skin to repair itself like the skin of a newborn. The discovery has implications for wound treatment and preventing some of the aging process in skin. Researchers identified a factor in the skin of baby mice controlling hair follicle formation. When it was activated in adult mice, their skin was able to heal wounds without scarring. The reformed skin even included fur and could make goose bumps. |
| Genetic risk of developing obesity is driven by variants that affect the brain Posted: 29 Sep 2020 09:34 AM PDT Some people are at higher risk of developing obesity because they possess genetic variants that affect how the brain processes sensory information and regulates feeding and behavior. The findings support a growing body of evidence that obesity is a disease whose roots are in the brain. |
| Study suggests link between unexplained miscarriages and how women perceive men's body odor Posted: 29 Sep 2020 09:34 AM PDT Women who have suffered unexplained repeated pregnancy loss (uRPL) have altered perceptions and brain responses to male body odors, in comparison to those with no history of uRPL, suggests a new study. |
| Complex interplay among cells guides them to where they need to go Posted: 28 Sep 2020 09:51 AM PDT Many cells in our bodies are on the move and somehow seem to "know" where to go. But how do they learn the location of their destination? This question is key to understanding phenomena such as the renewal of cells in our body, the migration of cancer cells, and especially how wounds heal. |
| Memory training for the immune system Posted: 28 Sep 2020 09:50 AM PDT The immune system will memorize the pathogen after an infection and can therefore react promptly after reinfection with the same pathogen. Now, scientists have deciphered new details of this process. |
| Fine-tuning stem cell metabolism prevents hair loss Posted: 28 Sep 2020 09:50 AM PDT An international research team has shown in mice that Rictor, a protein that helps to regulate the growth, energy, and oxygen consumption of cells, plays a key role in the cellular metabolism and longevity of hair follicle stem cells. |
| Identical signs of brain damage in sleep apnea and Alzheimer's Posted: 28 Sep 2020 07:34 AM PDT New research shows damage in the brain starts in the same place and spreads in the same way in sleep apnea, as in Alzheimer's disease. The study is the first to find Alzheimer's-like amyloid plaques in the brains of people with clinically-verified obstructive sleep apnea, a condition that affects more than 936 million people worldwide. |
| Patients' breathing test comes up short on accuracy, study finds Posted: 27 Sep 2020 06:40 PM PDT A routine test used to monitor patients' breathing may be unreliable and putting them at risk, a study suggests. Incorrect results can mean clinical staff fail to spot how unwell a patient with respiratory problems is becoming, researchers say. |
| Nerve cells let others 'listen in' Posted: 25 Sep 2020 08:36 AM PDT How many 'listeners' a nerve cell has in the brain is strictly regulated. In the environment of learning neurons, certain processes are set in motion that make signal transmission less exclusive. |
| COVID-19 shapes political approval ratings Posted: 25 Sep 2020 08:36 AM PDT During the early days of the pandemic, COVID-19 created a rally effect around political leaders, according to new study. The rise of COVID-19 cases was associated with a 15- to 20-point boost in approval for United States governors and an average 14-point gain for world leaders. It's unclear how long the effect lasts, but the health crisis might be a catalyst to help incumbent governments win re-election. |
| Novel neuroimaging study on dissociative symptoms reveals wounds of childhood trauma Posted: 25 Sep 2020 08:34 AM PDT Brain imaging analyses can uncover changes in functional connections between brain regions linked to dissociative symptoms. |
| New vulnerability found in lung squamous cancer may facilitate drug targeting Posted: 25 Sep 2020 08:34 AM PDT New cancer research shows the potential for targeting a specific circular RNA, known as CDR1as, to attack lung squamous cell cancer. |
| Potential drug target for dangerous E. coli infections identified Posted: 25 Sep 2020 08:34 AM PDT Treatment for a deadly E. coli strain may be possible in the future, after researchers identify a new molecular pathway that controls the potent Shiga toxin. |
| Secure nano-carrier delivers medications directly to cells Posted: 25 Sep 2020 08:33 AM PDT Researchers have developed a stable nano-carrier for medications. A special mechanism makes sure the drugs are only released in diseased cells. |
| Women could conceive after ovarian tumors, study shows Posted: 25 Sep 2020 08:33 AM PDT Women receiving fertility-sparing surgery for treatment of borderline ovarian tumors were able to have children, a new study shows. |
| Posted: 25 Sep 2020 08:33 AM PDT A novel mobile health program has proven to be an effective model for bringing opioid addiction treatment services directly to marginalized individuals, particularly the homeless. |
