By genetically altering fruit flies so that the heads of their sperm were fluorescent green or red, biologists were able to observe in striking detail what happens to live sperm inside the female. The findings may have huge implications for the fields of reproductive biology, sexual selection and speciation.

Cryotherapy, an interventional radiology treatment to freeze cancer tumors, may become the treatment of the future for cancer that has metastasized in soft tissues (such as ovarian cancer) and in bone tumors. Such patients are often not candidates for surgery and would benefit from minimally invasive treatment, say researchers.

In the first study ever done on the local health effects of the domes of carbon dioxide that develop above cities, researchers found that the domes increase the local death rate. The result provides a scientific basis for regulating CO2 emissions at the local level and points out a significant oversight in the carbon dioxide [...]

Butterflies are emerging in spring over 10 days earlier than they did 65 years ago, a shift that has been linked to regional human-induced climate change in an Australian-led study. The work reveals a causal link between increasing greenhouse gases, regional warming and the change in timing of a natural event.

Treating virulent influenza, sepsis, and other potentially deadly infections long has focused on looking for ways to kill viruses and bacteria. But new research shows that modulating the body’s own overeager inflammatory response to infection may help save more lives.
