Rice students work on weighty problem for doctors

A team of Rice engineering seniors designed a prototype device that uses suction cups attached to a vacuum pump to gently lift the abdomens of obese patients who are on their backs and under light sedation. The device, called R-Aides, could be invaluable to surgeons performing operations involving the upper or lower body.

Discovery of a new family of key mitochondrial proteins for the function and viability of the brain

A team of scientists has discovered a new family of six genes that regulate mitochondrial transport in neurons, which is crucial for brain activity and viability. The proteins are highly expressed in the nervous system and may be involved in neurological conditions such as Parkinson's disease and Charcot-Marie-Tooth disease.

Culturally sensitive research in United Arab Emirates pinpoints indoor air quality risks

A recent study from the University of North Carolina at Chapel Hill has pinpointed indoor air quality risks in the United Arab Emirates as a significant health concern. The research found that residents are exposed to high levels of pollutants such as sulfur dioxide, nitrogen dioxide, and formaldehyde, which can lead to respiratory iss...

WSU researchers say genes and vascular risk modify effects of aging on brain and cognition

Researchers found that older APOE ε4 carriers experience smaller brain volumes and poorer cognitive performance with even minor increases in systolic blood pressure. The study suggests an interaction between genetic and vascular risk factors contributes to age-related decline in brain and cognition.

Safer sex work spaces reduce violence and HIV risks for street-involved women

A study by BC-CfE and UBC found that safer indoor sex work spaces promote health and safety among street-based sex workers, reducing exposure to violence and HIV. These programs provide supportive housing, security measures, and health resources, increasing control over sex work transactions and improving relations with police.

Hot sauce ingredient reduces 'beer belly' fat as a weight-loss surgery alternative

Researchers at Brigham and Women's Hospital have discovered a potential new weight loss surgery alternative using capsaicin, which significantly reduced visceral abdominal fat and total body fat in lab tests. The procedure, vagotomy or vagal de-afferentation, may offer fewer side effects than traditional bariatric surgeries.

Whale population size, dynamics determined based on ancient DNA

A study using ancient DNA from archaeological sites found that gray whales had a substantially larger population before whaling and experienced a sharp recent decrease, consistent with whaling as the cause. The research suggests a pre-whaling decrease in population size of about 78,000 to 116,000 individuals.
