Biased reporting found in cancer prognostic studies

... patient with head and neck cancer. As researchers attempt to make sense of the growing mountains of information, some are beginning to question the validity and possible biases in many of the studies. To examine the question of selective reporting bias, Panayiotis A. Kyzas and colleagues from the Universit...

Plankton can run, but can't hide from basking sharks

However, this study shows that basking sharks seem to have rumbled them. As well as shedding new light on behavioural strategies of pl...

Scientists track stealth DNA elements in primate evolution

...ate over time to influence human evolution. In an attempt to understand these mechanisms, Dr. Batzer and his colleagues examined a subfamily of Alu elements in the human genome known as the AluYb lineage, and compared these elements to those in the genomes of other primate species, including chimpanzees, bo...

A protein in the eye may prevent immune response and protect eyes from disease

..., but its function has not been understood. In an attempt to understand F4/80, Stein-Streilein and her team have been following the immune cells (also known as antigen presenting cells) containing the protein. In previous studies, the team found that when these F4/80 containing cells bring antigens (foreign...

How exactly does the brain control breathing?

...se the journal as a forum to discuss the issue and attempt to resolve their differences in opinion. Both authors agree that the respiratory rhythm requires specialised nerve cells (central chemoreceptors) to power the rhythm, but the issue highly debated by Guyenet and Richerson is the precise location and ...

Atmosphere may cleanse itself better than previously thought

...tored into models that describe the atmosphere and attempt to predict how it will react to increasing quantities of hydrocarbon pollutants, which generate smog. But these models do not always function well, Francisco said, in part because OH radicals are in some ways an unknown quantity. "One of the biggest...

Research shows smoking adds a decade to reproductive age of IVF patients
