Moffitt Cancer Center researchers study 'ACT TIL' approach to treating metastatic melanoma

Researchers at Moffitt Cancer Center have developed a promising treatment approach for metastatic melanoma using chemotherapy and adoptive cell transfer (ACT) with tumor-infiltrating lymphocytes (TIL). The therapy achieved an impressive response rate of 38% in patients. A second-generation ACT TIL trial is currently enrolling patients.

Men, women have different stress reactions to relationship conflict

Researchers found that pregnant men experience increased stress levels during conflict discussions, depending on the level of hostility expressed by their partner. Women, on the other hand, show varying responses to relationship conflict, with some experiencing prolonged stress and others finding discussing difficult topics reassuring.

Decreased gene activity is likely involved in childhood risk for anxiety and depression

A new study from the University of Wisconsin-Madison suggests that decreased gene activity may be involved in childhood risk for anxiety and depression. Researchers found that young children with highly anxious temperaments have lower levels of specific genes in the amygdala, which can lead to overactivity and impaired learning about f...

Weight loss does not improve fertility

Researchers found that ovulation rates and quality remained unchanged after bariatric surgery, with only a minor shortening of the menstrual cycle. Weight loss improved sexual function, particularly desire and arousal, in obese women seeking pregnancy.

The evolutionary origins of our pretty smile

Researchers used non-invasive X-ray technology to study the jaws and teeth of a primitive jawed fish called Compagopiscis. The discovery provides solid evidence that teeth evolved along with or soon after the development of jaws in early vertebrates, shedding light on our evolutionary ancestry.

Doctors who go digital provide higher quality healthcare

A study by Lisa Kern and her team found that electronic health records (EHRs) are associated with higher quality ambulatory care in primary care physicians. The researchers compared the performance of physicians using either EHRs or paper records, assessing nine specific quality measures for a total of 466 primary care physicians.

Steps in the right direction for conservation

A University of York-led study reveals that strategically placed habitat 'stepping stones' can accelerate species range expansion, even in fragmented landscapes. The research offers a new approach to conservation planning, prioritizing areas where gaps between habitats are most difficult to cross.

Study shows overeating impairs brain insulin function, can lead to diabetes and obesity

Overeating can cause a malfunction in brain insulin signaling, leading to increased fatty acid levels, inflammation, and worsened insulin resistance. The study suggests that the brain's response plays a crucial role in developing type 2 diabetes, making it a potential target for improving insulin function.

Does true love wait? Age of first sexual experience predicts romantic outcomes in adulthood

Research suggests that the timing of first sexual experience can predict the quality and stability of romantic relationships in young adulthood. A study found that individuals who had their first sexual encounter later were more likely to have higher educational attainment, live with a partner, and be satisfied with their relationship.

Cleaner fracking

New water treatment firms are developing chemical treatments and evaporators to remove contaminants from fracking wastewater, which can then be reused. The cost of disposal is spurring oil and gas companies to adopt these technologies, limiting the amount of contaminated water that reaches people, plants, and animals.

Impact of autism may be different in men and women

A new study published in PLOS ONE found that men and women with autism spectrum conditions exhibit different cognitive abilities. Women with autism performed comparably to non-autistic women in tasks involving attention to detail, while men struggled with similar challenges.

Why are coastal salt marshes falling apart?

A recent study by the U.S. National Science Foundation found that excessive nutrient enrichment can cause salt marsh loss, leading to habitat destruction for fish and shellfish. The research showed that nutrient-enriched marshes experienced extensive erosion, converting vegetated areas into mudflats with reduced productivity.

Planet found in nearest star system to Earth

Astronomers detect the lightest exoplanet ever found around a Sun-like star, orbiting about six million kilometers away from the star. The newly discovered planet has a mass similar to Earth and orbits Alpha Centauri B every 3.2 days.
