Not every encounter between predator and prey results in death. A new study co-authored by a University of Tennessee, Knoxville, professor suggests that prey emit warning cues that can ultimately lead to both their survival and that of their predators. The hypothesis addresses a 150-year-old mystery of evolution on how warning signals of animals and plants arise and explains animals' instinctive avoidances of dangerous prey.
A longhorned beetle's sexy scent might make a female perk up her antennae. But when the males of several species all smell the same, a female cannot choose by cologne alone. For these beetles to find a mate of the right species, timing is everything, according to research from a University of Arizona-led team.
Phase I/II clinical trial results reported at the American Society for Clinical Oncology Annual Meeting 2015 show promising results for investigational drug brigatinib against ALK+ non-small cell lung cancer, with 58 of 78 ALK+ patients responding to treatment, including 50 of 70 patients who had progressed after previous treatment with crizotinib, the first licensed ALK inhibitor. Progression-free survival in patients previously treated with crizotinib was 13.4 months.
Obesity is a risk factor for breast cancer. A multi-institutional study presented at the American Society for Clinical Oncology Annual Meeting 2015 shows that female breast cancer survivors are able to lose weight through modest lifestyle changes.
A team of scientists based largely at the University of Kansas and the Burke Museum of Natural History and Culture in Washington has developed methods of using commercial-grade laser equipment to find and analyze fossils of dinosaurs. Their techniques are introduced via a paper in the journal PLOS ONE today.
This week from AGU: NASA Earth science, Climate change music and Tibetan Plateau evolution.
Do microbes grow differently on the International Space Station than they do on Earth? Results from the growth of microbes collected by citizen scientists in Project MERCCURI indicate that most behave similarly in both places.
Our environment can have a major impact on how we develop, and it turns out it's no different for cancer cells. In work published today in Neoplasia, a team of researchers reports that two different mouse models of breast cancer progressed differently based on characteristics of the tumor microenvironment -- the area of tissue in which the tumor is embedded.
Tell your child or spouse what they can eat and not what they can't. Telling your child to eat an apple so they stay healthy will work better than telling them not to eat the cookie because it will make them fat. A new Cornell discovery shows that 'Don't' messages don't work for most of us.
Latest generation genomic testing offers a chance for improvements in patient care, disease prevention and healthcare cost-effectiveness. A New England Journal of Medicine Special Report recommends that Congress incentivize development of massive data systems that doctors and regulators will need to make these tests safe and effective for patients. Existing regulatory oversight should be bolstered with ongoing postmarket data collection to study tests after they are in use and resolve lingering questions about health impacts of as-yet-poorly-understood genetic variants.
