Rising heat linked to faster telomere loss in wild Australian birds
Extreme heat can have a profound impact on wild animals, causing their death in the most extreme cases and leaving less visible marks in others. Understanding the effects of temperature changes on specific species could inform ...
What a locust can teach us about how neuromodulators alter odor processing
When you walk into a bakery and smell fresh cookies, the enticing smell draws you in. After you eat a handful of cookies, though, the same smell likely doesn't send you back for more. Researchers in the McKelvey School of ...
