Two designer drugs hit same lung cancer target, but only one is effective

...ten respond to both drugs, though only Tarceva has helped patients live slightly longer in clinical trials. Erbitux is a monoclonal antibody drug that binds to a portion of the EGFR receptor that extends outside the cell. This difference in action is the apparent explanation for why they performed different...

Of the roughly 900 total accessions, about 400 of unknown, but probable, sexual origin were studied. The others were either known to be crosses f...

World-first technology enables study of ancient bacteria

...ngineering Centre in the School of Engineering has helped design and produce a high-pressure system, which is the first of its kind in the world. Using titanium and stainless steel alloys, and sapphire windows, the Centre's experts have built an isolation system, as well as a special cutting chamber to ena...

DNA from feathers tells tale of eagle fidelity

...ral thesis. "Collecting feathers at the nest site helped us determine population parameters we wouldn't have been able to otherwise," she said. Those parameters, such as yearly survival rates and ratios of males to females, help conservation biologists monitor populations of rare or endangered species. No...

Environmental lessons from tsunami as world's coastal population doubles

...face of the tumor cell. In addition, the Penn team helped the immune system along by fusing the tumor antigen to a bacterial protein that seems to activate antigen-presenting cells. They have found that by doing this the immune system now recognizes regions of the HER-2/neu molecule that are not immunogenic...

Women feel more pain than men, research shows

... whilst the sensory-focused strategies used by men helped increase their pain threshold and tolerance of pain, it was unlikely to have any benefit for women," said Dr Keogh. "Women who concentrate on the emotional aspects of their pain may actually experience more pain as a result, possibly because the emo...

Survey Uncovers Surprising Attitudes Towards HIV Vaccine Research

... The results of the survey, says Mr. Murguía, have helped identify which populations researchers need to target for better understanding of HIV vaccine research, as well as which messages need to be tailored to specific populations. The NIAID team will work to lower the barriers that inhibit potential volun...

DDT-resistant insects have additional genetic advantage that helps resistance spread
