Here's why. (Rudmer Zwerver/Tanja Ivanova) Scientists recently discovered something about male mice that's utterly bananas: The distinctive scent of a banana stresses them out. Researchers from McGill University in Montreal, Quebec, learned about this unusual fruit aversion while analyzing spiking stress hormones in male mice when the males were close to pregnant or lactating females. The scientists reported in a new study that the males' hormonal shifts were triggered by the presence of a compound called n-pentyl acetate in the females' urine. It also happens to be the compound that gives bananas their distinctive smell.

(JGI/Jamie Grill via Getty Images) If you've ever had an imaginary argument in your head, you may have "heard" two voices at once. Your own inner voice and that of the other person in the quarrel. You may even "hear" the other person's accent, or the timbre of their voice. So what's happening in the brain when that inner monologue is running? How is it that you can "hear" your thoughts? As it turns out, the brain undergoes similar processes when you're thinking words as when you're speaking out loud. Full Story: Live Science (5/28)      Is climate change making the weather worse? (Roberto Machado Noa via Getty Images) United Nations climate scientists say it's "now or never" to stop catastrophic temperature rises and a breakdown of the climate systems on which our way of life depends. Reports of bomb-like blizzards and searing droughts paint a terrifying picture of the possible reality of climate change. But are we actually witnessing the weather getting worse? Unfortunately, the answer is yes.

By sampling sips of each other's urine, dolphins demonstrated a type of social recognition that begins with an exchange of whistles that are unique to specific individuals — much like human names. Scientists have long known that dolphins identify themselves using so-called signature whistles that are different for each dolphin and that they address one another by imitating such whistles. But researchers were uncertain if this copying showed that dolphins associate signature whistles with individual identity or with a more general concept such as "friend." Recently, scientists learned that not only do bottlenose dolphins demonstrate name recognition, they also replicate this recognition with another sense: taste.

(Learn the answer here) Dolphins lack olfactory bulbs, a brain structure needed to process smells They strongly dislike the smell of pee but can tolerate the taste They actually both smell and taste the pee, to be as accurate as possible in identifying friends   Sign Up  |    Update Profile  |    Unsubscribe Privacy Policy  |    Cookies Policy  |    Terms and Conditions CONTACT US: FEEDBACK  |    ADVERTISE Future US LLC © 1100 13th St. NW, Suite 1000, Washington, DC 20005
