Researchers have discovered a small molecule drug that can stop cancer cells from becoming resistant to chemotherapy. The new compound, which was tested in an animal model of melanoma, could serve as a powerful adjuvant to make current chemotherapies more effective. It works by thwarting cancer’s ability to survive, evolve, and adapt to the onslaught…

Animals first developed fever as a response to infections: the higher body temperatures primed their immune systems. At the time, 600 million years ago, virtually all animal species were cold-blooded. They had to spend long periods of time in warm areas of their habitat to achieve fever-range body temperatures. A researcher believes that pathogens may…

A new study demonstrates that the ears of bats come with a ‘built-in ambulance’ that creates the same physical effect as the sound of an ambulance passing by. Researchers think the study of ear-generated Doppler shifts in bat biosonar could give rise to new sensory principles that could enable small, yet powerful sensors. Press Release…

Methane is one of the most potent greenhouse gases. Hydroxyl radicals (OH) react with methane and break it down, but it’s been hard for scientists to get a handle on how much OH is present in the atmosphere at high-enough spatial and temporal resolution to be useful. New research got creative and correlated data from…
