P2P traffic control

Researchers propose a wireless peer-to-peer network to exchange timely information about traffic conditions, incidents, and accidents. The Autonet system uses local-area wireless technology to form an ad hoc network that can handle measurements for approximately 3,500 traffic incidents.

Absence of CLP protein can be indicative of oral cancer

A new study published in the Journal of Prosthodontics found that the absence of Human calmodulin-like protein (CLP) in oral epithelial cells may indicate oral cancer. The researchers used staining to compare CLP expression in normal and cancerous tissues, revealing a significant decrease or complete lack of CLP in malignant regions.

Spookfish uses mirrors for eyes

The four-eyed spookfish uses mirrors to focus light in its eyes, producing bright and high-contrast images. This unique adaptation gives the fish an edge in the deep sea, where spotting brief flashes of bioluminescent light can mean the difference between eating and being eaten.

Physical activity may not be key to obesity epidemic

Researchers from Loyola University Health System found no significant difference between African American women in metropolitan Chicago and Nigerian women in terms of calories burned during physical activity. The study suggests that dietary intake may be more important than energy expenditure level in the rising rates of obesity.

On a high-fat diet, protective gene variant becomes bad actor

A gene variant that protects against weight gain and insulin resistance becomes a bad actor on high-fat diets, new research suggests. Mice with the Ala12 variant show improved insulin sensitivity and better plasma lipid profiles on balanced diets but worsen these outcomes when fed a diet high in fat.

Big, old mice spread hantavirus

A recent study by University of Utah researchers identified bigger, older mice as the culprits behind hantavirus transmission. The study used fluorescent powders and radio transmitters to track contacts between mice, revealing that larger-bodied individuals were responsible for maintaining the disease in deer mouse populations.
