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.

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.
