Mtb produces specific protein that allows it to defuse and bypass body's security system

Tuberculosis, which kills over 2 million people each year, is caused primarily by infectious bacteria known as Mycobacterium tuberculosis - or Mtb. Mtb targets human immune cells as part of its strategy to avoid detection, effectively neutralizing the body's immune response.

New animal research finds life experiences influence brain development, behavior

Scientists presented new research today demonstrating the impact life experiences can have on genes and behavior. The studies examine how such environmental information can be transmitted from one generation to the next - a phenomenon known as epigenetics.

New human research shows benefits and challenges for aging brain

New human research released today shows the benefits and challenges for the aging brain. The studies probe common characteristics of normal aging - including memory loss, reduced sleep quality, and decision-making problems - and suggest the benefits of exercise, hormone treatment, and social interaction.

New clues about connections among fat, inflammation and insulin resistance

In a new study, scientists report that they substantially curbed weight gain, improved metabolism, and improved the efficacy of insulin in mice by engineering them to express a specific human enzyme in their fat tissue. Although the obesity prevention came at the significant cost of widespread inflammation, the research offers new clues about the connections among obesity, insulin resistance and type 2 diabetes, and inflammation.

New project to identify what gives biosonar the edge over human-made technologies

Sonar and ultrasound, which use sound as a navigational device and to paint accurate pictures of an environment, are the basis of countless technologies, including medical ultrasound machines and submarine navigation systems. But when it comes to more accurate sonar and ultrasound, animals' "biosonar" capabilities still have the human race beat.
