Q&A: When is screen time healthy and when is it not?

Researchers highlight five contexts – duration, time of day, purpose of use, interactivity, and content structure – to determine whether screen time is healthy or harmful. By examining these factors, individuals can protect themselves and their children from unhealthy screen behavior and create healthier digital environments.

Worker bumble bees help determine which baby bee will become queen

A new study reveals that worker bumble bees play a crucial role in determining the sex of baby bees, with juvenile hormone being the key trigger. The researchers found that when workers were treated with the hormone, they passed it to larvae through food, making them more likely to become queens.

DNA repair protein gene gone rogue may unlock new cancer treatments

Researchers discovered that overproduction of a DNA repair protein creates DNA damage mimicking BRCA mutations, which may respond to targeted treatments. Tumors with high levels of EXO1 protein exhibit characteristics similar to BRCA-mutant cells, suggesting personalized therapies could be effective.

Nicotine e-cigarettes reduce harmful chemical exposure, help smokers quit

A new study found that switching to a nicotine e-cigarette reduces toxicant exposure and improves quitting rates, with the nicotine group having a higher chance of quitting entirely. The study's results suggest that nicotine e-cigarettes could serve as an effective off-ramp for smokers seeking to reduce their tobacco use.

Stretchy implants could stick to arteries to treat high blood pressure

Researchers developed a new class of stretchy bioelectronics that can stick to biological tissue and relieve hypertension while causing less damage to surrounding tissue. The CaroFlex device uses gentle electrical frequencies to modulate the baroreceptor reflex, providing effective treatment for drug-resistant hypertension.

New reactor design produces renewable methane from carbon dioxide

A new reactor design efficiently converts carbon dioxide into methane using microbial electrosynthesis systems, achieving high energy efficiency and scalability. The system produces nearly two gallons of methane per liter of reactor volume per day, making it a potential pathway for converting CO2 into a storable fuel.

Child abuse may be connected to changes in development, body regulation

A new study published in Molecular Psychiatry found that child abuse is associated with disrupted development and decreased ability to maintain stable bodily functions. The research suggests that different types of maltreatment affect children differently, with boys being more susceptible to negative effects than girls.

Ultrahigh-energy cosmic messengers may carry ultraheavy secrets

Research suggests that some ultrahigh-energy cosmic rays could consist of atomic nuclei heavier than iron, losing energy more slowly as they travel through intergalactic space. This finding could help narrow down the possible sources of these particles and impact how we search for their origins.

Hydraulic brain: Body motion linked to fluid movement in the brain

A study using mice and simulations found that abdominal contractions compress blood vessels connected to the spinal cord and brain, enabling gentle brain movement that facilitates cerebrospinal fluid flow and potentially removes neural waste. This mechanism may explain why exercise is thought to benefit brain health.

Q&A: What do teenagers need from their parents?

Penn State professor Greg Fosco emphasizes the importance of parental monitoring, autonomy-supportive parenting, and fostering a sense of purpose in teenagers' lives. Research suggests that when adolescents perceive a stable relationship with their parents, their well-being suffers, while having a sense of purpose is linked to lower su...
