Researchers develop hard X-ray laser to determine structure of biomolecules

Unraveling the molecular basis of life is an age-old quest of humanity. A breakthrough towards this goal was reported in a pair of studies published Feb. 3 in the scientific journal Nature, detailing a new method developed to determine structures of biomolecules based on diffraction from protein nanocrystals that are so small that they are not even visible under the microscope.

Small molecules may inhibit entry of Ebola into human cells

Ebola, a virus that causes deadly hemorrhagic fever in humans, has no known cure or vaccine. But a new study by University of Illinois at Chicago scientists has uncovered a family of small molecules which appear to bind to the virus's outer protein coat and may inhibit its entry into human cells.

Turns mortal heart attacks into non-mortal heart attacks -- NIH study

Three weeks of oral resveratrol or Longevinex- ingestion prior to an induced heart attack returned microRNA activity close to their pre-event levels in excised animal hearts. Among thousands of microRNA's studied, just six were attributed to exerting the majority of the gene-switching effects measured in the animal heart study - four microRNA optimally regulated by Longevinex- and two optimally by plain resveratrol.

Scientist discovers molecular switch controlling synthesis of ribosomes

A scientist from the Florida campus of The Scripps Research Institute has discovered a molecular switch that controls the synthesis of ribosomes. Ribosomes are the large machineries inside all living cells that produce proteins, the basic working units of any cell. These new findings offer a novel target for potential treatments for a range of diseases, including cancer.

Researchers develop new lung imaging technique that causes minimum tissue disruption

Fast-moving objects create blurry images in photography, and the same challenge exists when scientists observe cellular interactions within tissues constantly in motion, such as the breathing lung. In a recent UCSF-led study in mice, researchers developed a method to stabilize living lung tissue for imaging without disrupting the normal function of the organ.
