Scientists ID molecular 'switch' in liver that triggers harmful effects of saturated and trans fats

Dana-Farber Cancer Institute researchers have identified a molecular mechanism in the liver that explains, for the first time, how consuming foods rich in saturated fats and trans-fatty acids causes elevated blood levels of cholesterol and triglycerides and increases one's risk of heart disease and certain cancers. In the Jan. 28 issue of Cell, scientists led by Bruce Spiegelman, PhD, rep...

Successful Test Of Single Molecule Switch Opens The Door To Biomolecular Electronics

A team of scientists led by biophysicist Stuart Lindsay from the Biodesign Institute at Arizona State University has created the first reproducible single molecule negative differential resistor ?and in the process has developed a groundbreaking experimental technique that provides a “roadmap?for designing single-molecule devices based on biochemistry. The findings were presented Feb. 18...

Bad aftertaste? New sensory on/off switch may 'cure' bane of artificial sweetener search

Chemistry and biology researchers at Virginia Tech have enhanced the abilities of the molecules they are creating to deliver killing blows to cancer cells. The man-made molecular complexes enter cancer cells and, when signaled, deliver killing medicine or cause the cell to change. The new supermolecules have more units that will absorb light - providing more control over the range of light freque...

'Exercise pill' switches on gene that tells cells to burn fat

By giving ordinary adult mice a drug - a synthetic designed to mimic fat - Salk Institute scientist Dr. Ronald M. Evans is now able to chemically switch on PPAR-d, the master regulator that controls the ability of cells to burn fat. Even when the mice are not active, turning on the chemical switch activates the same fat-burning process that occurs during exercise. The resulting shift in energy b...

Beetle-inspired switch uses water for bonding

Imagine this: A tiny, fast switch that uses water droplets to create adhesive bonds almost as strong as aluminum by borrowing a mechanism found in palm beetles. The new beetle-inspired switch, designed by Cornell University engineers, can work by itself on the scale of a micron -- a millionth of a meter. The switches can be combined in arrays for larger applications like powerful adhesive...
