How does friendly fire happen in the pancreas?

Scientists at Helmholtz Zentrum München have discovered a mechanism used by the immune system to prepare for attacks on insulin-producing cells in the pancreas. The team identified a signaling pathway triggered by miRNA92a, which leads to an increase in immune cells that promote autoimmunity. Targeted intervention using antagomirs may ...

Study shows higher levels of Alzheimer's-related tau protein found in children aged 18 years and under with early onset psychosis

Researchers analyzed blood plasma levels of tau protein in patients with early onset psychosis (EOP) aged 18 and under, finding higher levels than controls. The study suggests altered tau protein metabolism in EOP, which may have implications for understanding the pathophysiology and developing new treatment strategies.

John Innes Centre scientists solve 60-year-old Septoria mystery

Plant breeders have struggled to combine high yield and resistance to Septoria in wheat varieties, but John Innes Centre researchers have found a genetic connection between the two traits. The study reveals that nearly 60 years ago, breeding decisions inadvertently linked increased susceptibility to Septoria with higher yields.

Understanding bacteria's slimy fortresses

Researchers tracked a single bacterial cell as it grew into a mature biofilm of 10,000 cells. They found that the bacteria secrete a glue-like substance to keep from getting washed away and protect themselves from competing bacteria. A key gene, RbmA, plays a crucial role in developing a denser, stronger biofilm.

Focusing on pleasure of eating makes people choose smaller portions

A study published in the Journal of Marketing Research found that people will choose smaller portions of food when they are enticed by the multisensory pleasure of taste, smell, and texture. This approach can lead to positive outcomes for consumer satisfaction and health, while also benefiting profits in the food industry.

Where does cisplatin bind?

Researchers develop universal assay to detect cisplatin cross-linking sites in the genome. They found that mitochondrial DNA is a major target of cisplatin's action, while nuclear DNA is less affected.

Male mice model human speech defect

Researchers at Duke University found that male mice carrying a genetic mutation known to affect human speech struggle with sequencing phonemes into words. The study used new statistical tools to analyze the structure of ultrasonic mouse songs, revealing a similar impact on sequence complexity as seen in humans.
