Paleontologists can still hear the echo of the death knell that drove the dinosaurs and many other organisms to extinction following an asteroid collision at the end of the Cretaceous Period 65 million years ago. “The evolutionary legacy of the end-Cretaceous extinction is very much with us. In fact, it can be seen in virtually [...]

Animal research has shown that binge drinking — even just once — during early pregnancy can cause numerous problems for the fetus, including early postnatal death. Fetal zinc deficiency may explain some of the birth defects and neurodevelopmental abnormalities associated with alcohol exposure. New rodent findings are the first to show that dietary zinc supplements [...]
A new species of babbler has been described from Guangxi province in south-west China close to the border with Vietnam. Named Nonggang Babbler Stachyris nonggangensis, after the reserve at which it was discovered, this new species is closely related to Sooty Babbler S. herberti but is larger and has white crescent patches behind the ear [...]

Researchers have made a major breakthrough in the international fight against malaria, which claims the life of a child across the world every 30 seconds. Scientists have been able to deactivate the final stage of the malaria parasite’s digestive machinery, effectively starving the parasite of nutrients and disabling its survival mechanism. This process of starvation [...]
Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light, scientists have reported in Clinical Cancer Research.

A grid of small arteries at the surface of the brain redirects flow and widens at critical points to restore blood supply to tissue starved of nutrients and oxygen following a stroke, a study published this week has found.
A new study confirms that the use of estrogen plus progesterone increases the risk of both ductal and lobular breast cancer far more than estrogen only; suggests a two-year “safe” period for the use of estrogen and progesterone; and finds that the increased risk for ductal cancers observed in long-term past users of hormone replacement [...]
