U-M researchers use nanoparticles to target brain cancer

...dical School and professor of environmental health sciences at the School of Public Health. Treating brain tumors is traditionally difficult because of the blood-brain barrier, which prevents harmful substances from traveling through the bloodstream into the brain. In order for chemotherapy to treat a tum...

Antibody extends life of mice with breast cancer

...D., associate professor of clinical and laboratory sciences in the UB School of Medicine and Biomedical Sciences, is senior author on the study. "This antibody binds with a carbohydrate on the tumor cell surface that is involved in adhesion of the cell during the metastatic process," said Rittenhouse-Olson....

From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea

Powerful genome ID method extended to humans

...her ways, said Philip Green, a professor of genome sciences at the University of Washington who edited the PNAS paper. Geneticists often say that humans have 99.9 percent of their DNA in common. But, Green said, "individuals occasionally have big differences in their chromosome structure. You sometimes fin...

Fast-freeze snapshot yields new picture of nerve-muscle junction

... Janet Richmond, associate professor of biological sciences at the University of Illinois at Chicago, is the corresponding author. Previously, Richmond developed a technique that allows a more precise understanding of how synaptic proteins affect release of neurotransmitter chemicals at the junctions -- the ...

Mysterious 'neural noise' actually primes brain for peak performance

...Pouget, associate professor of brain and cognitive sciences at the University of Rochester. Pouget's work for the first time connects two of the brain's biggest mysteries; why it's so noisy, and how it can perform such complex calculations. As counter-intuitive as it sounds, the noise seems integral to mak...

'Failed' experiment yields a biocontrol agent that doesn't trigger antibiotic resistance

...juGon is helping to ensure the future of microbial sciences at the UW-Madison. "We have one of the largest and most prominent communities of microbiologists in the country on the UW-Madison campus," he says. "It's important to provide jobs and opportunities in Madison for people who train here." And beyo...

Scientists crack rhino horn riddle
