Overexpression of Notch1 in temporal lobe epilepsy

The study found that overexpression of Notch1 in temporal lobe epilepsy rats reduced seizure frequency and brain discharges. Increased presence of Notch 1 and hairy and enhancer of split-1 was observed in intractable temporal lobe epilepsy patients, suggesting a potential role for Notch signaling in the disease.

Calcium supplements not associated with increased risk of cardiovascular disease in women

A new study by researchers at Brigham and Women's Hospital found that taking calcium supplements did not increase the risk of cardiovascular disease in women. The study, published in Osteoporosis International, examined 74,245 women over 24 years and found no association between calcium supplement intake and heart attack or stroke.

Molecular high-speed origami

The study reveals that chaperones, like GroEL and GroES, use a high-speed origami-like mechanism to accelerate protein folding. This process, which was previously thought to be energetically unfavorable, is now understood to be a favorable reaction, allowing proteins to fold faster than they are produced.

Love makes you strong

Researchers discovered that young adults in romantic relationships exhibit reduced neuroticism over time. The study found that partners support each other and positive experiences change thought structures, leading to increased stability. This effect is observed in both men and women, with long-term relationships having a stronger impact.

Research indicates coyote predation on deer in East manageable

Research indicates that coyote predation on fawns in the East may not be significant enough to cause deer population decline, especially with reduced doe harvests. In contrast, extremely low doe survival rates combined with high fawn mortality support stabilization of Eastern deer populations.

Teaching robots right from wrong

A team of scientists from Tufts University, Brown University, and Rensselaer Polytechnic Institute is working on a project to create robots capable of making moral decisions. The researchers aim to develop formal frameworks for modeling human-level moral reasoning that can be verified and implemented in computational architectures.

Life on cheese

Scientists investigate Vorarlberger Bergkäse, a regional Austrian cheese, to understand its unique microbiome. The study reveals the presence of halophilic microbe Halomonas on young rinds, which plays an unknown role in cheese-making.

How to increase the survival rate of motor neurons after spinal root avulsion

Researchers found that preconditioning crush can increase the survival rate of motor neurons after spinal root avulsion. The study, published in Neural Regeneration Research, discovered that induction of heat shock protein 27 inhibits neuronal nitric oxide synthase, attenuating cytotoxic effects and preventing ventral motor neuron loss.

Extinct kitten-sized hunter discovered

A Case Western Reserve University student and his mentor have discovered an ancient kitten-sized predator that lived in Bolivia about 13 million years ago. The animal would have been about the size of a marten and probably filled the same ecological niche as larger sparassodonts.

Few women at high-risk for hereditary breast and ovarian cancer receive genetic counseling

A recent study published in the Journal of Community Genetics found that only one in twenty-two high-risk women received BRCA genetic counseling. Despite having a diverse population, no significant differences were associated with factors like age, race, or family size. The researchers urge providers and patients to be more aware of th...

Study helps explain why MS is more common in women

Researchers found that females susceptible to MS produce higher levels of the blood vessel receptor protein S1PR2 than males, leading to the inflammation that causes MS. The study's findings have implications for developing new treatments, including a drug that disables S1PR2.
