Shorter course of radiation therapy is safe for patients with early-stage breast cancer who have undergone mastectomy and reconstruction

Researchers found a shorter course of radiation therapy provides equivalent protection against breast cancer recurrence and physical side-effects, but reduces life disruption and financial burden. Patients reported less burden on their time and finances, with improved quality of life.

Metaphors for human fertilization are evolving, study shows

A new study by Yale sociologist Rene Almeling found that despite the shift in social and scientific views on gender, sex, and sexuality, a common metaphor of active sperm penetrating a passive egg remains widely used. However, another more egalitarian metaphor describing sperm and egg as two halves of a whole is also circulating.

Give abandoned croplands a second chance to boost climate mitigation and food security, urges new study

Researchers found that globally abandoned cropland could feed up to 476 million people per year if recultivated and help pull planet-warming carbon dioxide from the atmosphere through reforestation. The study highlights the potential of this often-neglected resource in supporting both food security and climate change mitigation.

Exposure to daylight rather than artificial light improves blood sugar control and nutrient use in individuals with type 2 diabetes, small Dutch study finds

A small Dutch study found that exposure to natural light improved blood sugar control and nutrient use in individuals with type 2 diabetes. The study showed that participants experienced better blood sugar levels, increased fat as an energy source, and improved clock gene expression when exposed to natural light.

Immune cell map reveals origin of subcellular response to microbes, researchers report

Researchers have created an 'immune cell map' that reveals the origin of neutrophils' subcellular response to microbes. The study found that a specific type of glycoprotein is responsible for the restricted subcellular origin, and this discovery may lead to refined personalized immune responses.
