Earth's orbital rhythms link timing of giant eruptions and climate change

An international team of scientists has synchronized key climate records from the Atlantic and Pacific Oceans to unravel the sequence of events during the last million years before the extinction of the dinosaurs at the Cretaceous/Paleogene boundary. New high resolution geochemical records for the first time reveal when and how two major eruption phases of gigantic flood basalt volcanism had an impact on climate and biota in the late Maastrichtian era 66 to 67 million years ago.

Adaptability of some coral reef fish to rising temperatures

Researchers have found that reef fish from the Arabian Gulf, the world's hottest sea, exhibit a higher tolerance to temperature fluctuations compared to those from more thermally stable coral reefs. However, the Arabian Gulf hosts fewer fish species overall, indicating that only certain fishes can withstand rising global temperatures.

Insect populations are declining -- and that is not a good thing

Using two species of flies from different climates -- one from the cool, high-altitude forests of Northern California, the other hailing from the hot, dry deserts of the Southwest -- scientists discovered remarkable differences in the way each processes external temperature.

New biosensor can detect airborne bird flu in under 5 minutes

As highly pathogenic H5N1 avian influenza continues to spread in the U.S., posing serious threats to dairy and poultry farms, both farmers and public health experts need better ways to monitor for infections, in real time, to mitigate and respond to outbreaks. Newly devised virus trackers can monitor for airborne particles of H5N1.

New 4D Brain Map reveals potential early warning signs of multiple sclerosis

Using an animal model of multiple sclerosis (MS), researchers have created a four-dimensional brain map that reveals how lesions similar to those seen in human MS form. These findings provide a window into the early disease state and could help identify potential targets for MS treatments and brain tissue repair.
