Gold nanorods shed light on new approach to fighting cancer
Researchers have shown how tiny "nanorods" of gold can be triggered by a laser beam to blast holes in the membranes of tumor cells, setting in motion a complex biochemical mechanism that leads to a tumor cell's self-destruction. view more (2007-10-17)
UCR scientists manipulate ripples in graphene, enabling strain-based graphene electronics
Graphene is nature's thinnest elastic material and displays exceptional mechanical and electronic properties. view more (2009-07-27)
MSU scientists find new gene that helps plants beat the heat
Michigan State University plant scientists have discovered another piece of the genetic puzzle that controls how plants respond to high temperatures. That may allow plant breeders to create new varieties of crops that flourish in warmer, drier climates. view more (2008-10-07)
Elevated testosterone kills nerve cells
A Yale School of Medicine study shows for the first time that a high level of testosterone, such as that caused by the use of steroids to increase muscle mass or for replacement therapy, can lead to a catastrophic loss of brain cells. view more (2006-09-27)
Detecting anthrax proteins at ultralow concentrations
A new laboratory method for quickly detecting active anthrax proteins within an infected blood sample at extremely low levels has been developed. view more (2005-08-29)
Portuguese distinguished in article about stomach cancer
Three Portuguese researchers are co-authors of a scientific article about hereditary stomach cancer, published in the medical journal "New England Journal of Medicine" and recently awarded the Benjamin Castleman 2002 Award. Attributed by the International Academy of Pathology, the prize distinguishes the best scientific work in human pathology... view more... (2002-06-18)
University of Pittsburgh researchers crack code of 3-D structure in key metabolic protein
Using X-ray crystallography, researchers at the University of Pittsburgh School of Medicine led by structural biologist Joanne I. Yeh, Ph.D., have become the first to decipher the three-dimensional structure of a membrane-bound enzyme that plays a crucial role in glycerol metabolism - a discovery that could lead to important advances against... view more...

Self-digestion as a means of survival
In times of starvation, cells tighten their belts: they start to digest their own proteins and cellular organs. The process - known as autophagy - takes place in special organelles called autophagosomes. view more (2009-02-27)
Researchers identify mechanism that helps bacteria avoid destruction in cells
Infectious diseases currently cause about one-third of all human deaths worldwide, more than all forms of cancer combined. Advances in cell biology and microbial genetics have greatly enhanced understanding of the cause and mechanisms of infectious diseases. view more (2009-10-12)
Common bacteria pirate natural mechanism to get inside cells
Bacteria and viruses utilize a natural mechanism to get inside cells and grow, researchers say. view more (2006-01-26)
Rockefeller researchers show evidence of asymmetric cell division in mammalian skin
It took almost 10 years for Elaine Fuchs, Ph.D., a Howard Hughes Medical Institute investigator at Rockefeller University, to find a postdoctoral fellow who shared her curiosity for the direction of cell divisions in the skin. view more (2005-08-17)
Researchers collaborate to understand phenomena controlling PEM fuel cell performance, durability
Two researchers at Sandia National Laboratories are working to understand several key phenomena that control hydrogen-fueled PEM (proton exchange membrane or polymer electrolyte membrane) fuel cells. One, Ken S. Chen, is developing computational models to describe the phenomena while the other, Mike Hickner, is performing physical experimentation. view more (2006-01-27)
Figuring out function from bacteria's bewildering forms
The constellation of shapes and sizes among bacteria is as remarkable as it is mysterious. Why should Spirochaeta halophila resemble a bedspring coil, Stella a star and Clostridium cocleatum a partly eaten donut? No one really knows. view more (2006-07-19)
Penn researchers discover key to how SARS virus infects cells
Researchers from the University of Pennsylvania School of Medicine have found that inhibitors of an enzyme called cathepsin L prevent the SARS (severe acute respiratory syndrome) virus from entering target cells. SARS is caused by an emergent coronavirus. view more (2005-08-02)
Researchers study role of natural organic matter in environment
The decomposition of plant, animal and microbial material in soil and water produces a variety of complex organic molecules, collectively called natural organic matter. These compounds play many important roles in the environment. view more (2006-12-12)
Solution to bacterial mystery promises new drugs
A 25-year quest to identify the first biochemical step that many disease-causing bacteria use to build their membranes has led to a discovery that holds promise for effective, new antibiotics against these bacteria. view more (2006-09-01)
High-res view of zinc transport protein
How much difference can a tenth of a nanometer make? When it comes to figuring out how proteins work, an improvement in resolution of that miniscule amount can mean the difference between seeing where atoms are and understanding how they interact. view more (2009-09-14)
New studies on the Mediterranean diet confirm its effectiveness for chronic disease prevention
Scientists of the Instituto de Nutrición y Tecnología de los Alimentos (Institute of Nutrition and Food Technology) of the University of Granada (UGR, Spain) have been doing research into the positive effects of Mediterranean diet's ingredients on health. view more (2008-09-08)
The Nobel Prize in Chemistry 2003
The two American scientists Peter Agre, 54, and Roderick MacKinnon, 47, will receive this years Nobel Prize in Chemistry "for discoveries concerning channels in cell membranes". view more (2003-10-09)
New windows opened on cell-to-cell interactions
Applying biological molecules from cell membranes to the surfaces of artificial materials is opening peepholes on the very basics of cell-to-cell interaction. view more (2009-07-23)
