New light has been shed on solar power generation using devices made with polymers. Researchers identified a new polymer -- a type of large molecule that forms plastics and other familiar materials -- which improved the efficiency of solar cells. The group also determined the method by which the polymer improved the cells' efficiency. The polymer allowed electrical charges to move more easily throughout the cell, boosting the production of electricity -- a mechanism never before demonstrated in such devices.
Rising temperatures and shifting precipitation patterns may get the lion’s share of our climate change attention, but predators may want to give some thought to wind, according to a zoologist’s study, which is among the first to demonstrate the way “global stilling” may alter predator-prey relationships.
The first human tests of using a perfluorocarbon (PFC) tracer in combination with non-invasive magnetic resonance imaging to track therapeutic immune cells injected into patients with colorectal cancer have been reported by scientists.
Domestic violence occurs at least as frequently, and likely even more so, between same-sex couples compared to opposite-sex couples, according to a new review of research. Abuse is underreported in same-sex couples due to the stigma of sexual orientation, researchers note.
A possible 6,800 new Ebola cases this are predicted this month, as suggested by researchers who used modelling analysis to come up with their figures. The rate of new cases significantly increased in August in Liberia and Guinea, around the time that a mass quarantine was put in place, indicating that the mass quarantine efforts may have made the outbreak worse than it would have been otherwise.
Rhinorex, a newly discovered dinosaur from the Late Cretaceous period, had an impressive nose. Call it the Jimmy Durante of dinosaurs – a newly discovered hadrosaur with a truly distinctive nasal profile. The new dinosaur, named Rhinorex condrupus by paleontologists from North Carolina State University and Brigham Young University, lived in what is now Utah approximately 75 million years ago during the Late Cretaceous period.
A leading Dartmouth researcher, working with The Melanoma Genetics Consortium, GenoMEL, an international research consortium, co-authored a paper published today in the Journal of the National Cancer Institute that proves longer telomeres increase the risk of melanoma.
Researchers in Biomedical Informatics at IMIM (Hospital del Mar Medical Research Institute) and at the Universitat Politècnica de Catalunya (UPC) have recently published a study in eLife showing that RNA called non-coding (IncRNA) plays an important role in the evolution of new proteins, some of which could have important cell functions yet to be discovered.
A team of Spanish researchers have obtained the first partial genome sequence of an ancient pig. Extracted from a sixteenth century pig found at the site of the Montsoriu Castle in Girona, the data obtained indicates that this ancient pig is closely related to today's Iberian pig. Researchers also discard the hypothesis that Asian pigs were crossed with modern Iberian pigs.
