Engineered virus is effective against triple negative breast cancer cells

Researchers have discovered a potential cure for triple negative breast cancer using a vaccinia virus engineered to make cancer cells produce radioiodine. The discovery, published in The FASEB Journal, has shown promising results in laboratory experiments and offers new hope for treating deadly and resistant forms of cancer.

A digital test for toxic genes

Tel Aviv University researchers developed a computer algorithm that predicts which genetic genes are lethal to cells when overexpressed. The new algorithm, called Expression Dependent Gene Effects (EDGE), helps guide metabolic engineering to produce new chemicals in more efficient ways.

Single gene separates queen from workers

Researchers have identified a single gene, Ultrabithorax (Ubx), that determines the distinct leg features of worker honey bees, enabling them to collect and transport pollen. The gene plays a critical role in the evolution of social behavior among honey bees, separating queens from workers.

ADHD medication saves lives on the road

A large registry study found that up to half of transport accidents involving adult men with ADHD could be avoided if they were taking medication. The results demonstrate a significant decrease in risk of serious transport accidents among men with ADHD who received medication, with a 45% increased risk compared to those without ADHD.

Connectedness, human use of buildings shape indoor bacterial communities

A study published in PLOS ONE found that architectural design characteristics, human use, and ventilation sources influence bacterial community structure in buildings. Dust samples revealed over 30,000 types of bacteria, with distinct communities found in high-traffic areas and restrooms containing organisms associated with the human gut.

Two stressed people equals less stress

A new study from the USC Marshall School of Business found that sharing feelings with someone having a similar emotional response to a threatening situation can help decrease stress. By discussing their emotions, individuals can experience reduced levels of stress-related hormones like cortisol.

Weapons tied to repeat domestic abuse

A new MSU study found that the use of knives, guns, or vehicles in initial abuse incidents is a key predictor of ongoing domestic violence. Women who experienced such incidents were more likely to make follow-up calls to police for physical and nonphysical abuse.

Penguin future uncertain in the face of climate change

A study published in PLOS ONE suggests that penguins' ability to respond to changes in sea ice concentrations is disrupted by extreme environmental events. Adélie penguins can cope with reduced summer sea ice, but extreme events like giant icebergs reduce their access to prey and overall efficiency.

UA researchers trace bat killer's path

Researchers at the University of Akron identify fungi closely related to WNS, predicting future of North American bats; a single bat can eat thousands of insects, critical to controlling agricultural pests. The fungus can survive in caves without bats, making reintroduction attempts doomed to failure.

China's reliance on lower-paid contract nurses may compromise patient care

A recent study from Columbia University School of Nursing found that hospitals with a high number of contract nurses had significantly higher levels of patient dissatisfaction and lower quality ratings. The study suggests that equal pay for equal work is essential for better patient outcomes, as low job satisfaction among contract nurs...
