Gene that guides earliest social behaviors could be key to understanding autism

A new animal study points to a gene that controls early social behaviors and may be linked to autism. Exposure to certain drugs during embryonic development can alter this gene, leading to social behavior changes similar to those found in individuals with autism. Researchers were able to reverse some effects using an experimental drug.

Gully erosion prediction tools can lead to better land management

Researchers developed a modeling framework using remote sensing data to predict gully erosion susceptibility. They found that spatiotemporal changes in land cover and precipitation were crucial in predicting gully formation in agricultural areas, with 7.4% of the study area having an elevated risk of developing gullies.

Witchcraft beliefs are widespread, highly variable around the world

A global dataset reveals widespread witchcraft beliefs varying substantially between countries and world regions. Higher education and economic security are associated with lower belief in witchcraft. Weak institutions, low social trust, and conformist culture also correlate with higher witchcraft prevalence.

Do skin moisturizers help prevent eczema in infants?

Early application of skin moisturizers is an effective strategy for preventing atopic dermatitis (AD) in high-risk infants. A systematic review and network meta-analysis found that three types of emollients, including cream, emulsion, and mixed types, are comparable in preventing AD; however, emollient emulsion may be the optimal option.

Fewer patients with PTSD survive COVID

Researchers from UCSF and the San Francisco VA Health Care System found that veterans with PTSD had an 8% increased risk of death and a 9% increased risk of hospitalization compared to those without psychiatric diagnoses. Patients with psychosis had a 58% increased risk of death and a 66% increased risk of hospitalization.

Unexpected cognitive deteriorations in epilepsy

A study published in Annals of Neurology found that patients with severe epilepsy who undergo surgical tissue analysis are at risk for rare secondary diseases, including inflammation and incipient Alzheimer's dementia-like. These conditions can lead to unexpected cognitive decline months or years after surgery.

COVID-19 vaccine gives substantial protection against reinfection

A new study published in PLOS Medicine found that COVID-19 vaccination provides significant protection against reinfection, with varying levels of effectiveness (60-94%) across different variants. The study analyzed data from over 200,000 people in Denmark and showed that vaccination offered up to 71% protection during the Alpha period...

Cultural differences affect how we support close friends and family

A study by Osaka Metropolitan University found that Japanese university students are hesitant to provide social support without explicit request. In contrast, American students are more willing to offer assistance when they recognize someone is in need. The research aims to encourage Japanese people to provide help when it's needed.

Low to moderate stress is good for you

A new study found that low to moderate levels of stress improve working memory and brain function, allowing individuals to optimize cognitive performance. In contrast, chronic high-stress levels can lead to changes in brain structure and increased susceptibility to illnesses like heart disease and high blood pressure.

Gene-delivering viruses reach the brain in step toward gene therapy for neurological diseases

Researchers have engineered a family of adeno-associated viral vectors that can deliver cargo to the primate brain, offering a safer and more efficient way to treat genetic diseases. The PAL family of AAVs has been shown to be three times better at delivering their cargo into the brain than current leading AAV delivery vehicle AAV9.
