Posted on September 27, 2019 by Lynne Peeples

Every day, people make countless decisions, big and small: Should I buy that new house? Do I want chocolate or vanilla ice cream? A recent study suggests that when faced with uncertainty regarding a choice, how a person evaluates their … Continue reading →

Posted on June 14, 2019 by Natasha Gilbert

Rich biodiversity depends on the ability of species to coexist. And yet, ecologists are still grappling with the requisite mechanisms. Recent findings published in Nature suggest that predators might not be as helpful a driver of species coexistence as … Continue reading →

Journal Club: Researchers catch the mouse brain in the act of learning something new

Posted on November 5, 2018 by Amber Dance

Neurobiologists have captured, for the first time, the moment in a mouse’s brain when it first learns something new: in this case, that a beep signals a delicious droplet of sugar water. The results, recently reported in Nature Neuroscience, support a famous … Continue reading →

Journal Club: Tracing light’s effect on mood and learning in mice from the eye to deep within the brain

Posted on October 11, 2018 by Carolyn Beans

To the mammalian eye, light offers more than just sight. “Light is so important for many innate functions,” says neuroscientist Samer Hattar of the National Institute of Mental Health (NIMH). “We really don’t appreciate the importance of light in our … Continue reading →

Journal Club: Butterflies get diversity boost from associations with ants, plants

Posted on October 5, 2018 by Charlotte Schubert

Harvard University evolutionary biologist Naomi Pierce began studying Lycaenidae butterflies as a graduate student in the 1980s. But only recently has she accumulated enough data, from her team’s work and others’, to begin to address the question that has long … Continue reading →

Journal Club: Proprioceptive neurons offer new insights into a “sixth sense”

Posted on June 25, 2018 by Jessica P. Johnson

Proprioception allows people to know the position of parts of the body without seeing them, enabling us to touch type, walk in the dark without falling over, or drive a car while looking at the road. Defects in this sensory … Continue reading →

Journal Club: Damaged reefs get quieter, causing fewer fish to hear their way home

Posted on April 30, 2018 by Carolyn Beans

A healthy coral reef creates quite the underwater racket. Reef croakers croak, damselfish woop-woop-woop, and clown fish sound thuds like a woodpecker at a tree. But a new study reports that climate-change related disturbances can turn down the volume … Continue reading →

Journal Club: Canines remember who cooperates, suggesting principles similar to those seen in human interaction

Posted on March 15, 2018 by Carolyn Beans

Human cooperation often comes down to one key understanding: You help me, I’ll help you. Social animals, including dogs, also help others, even nonrelatives. But many scientists assume that animal cooperation is a different breed. They see animals as less … Continue reading →

Journal Club: Cooler temperatures might make some mosquitoes better dengue spreaders

Posted on October 20, 2017 by Amber Dance

Migrating mosquitoes that carry diseases from the tropics to cooler climes might be better at spreading disease in their new, cooler home, according to a recent study in the Proceedings of the Royal Society B. Researchers from Yale University in … Continue reading →

Journal Club: Illuminating the neurons that help fruit fly larvae escape danger

Posted on September 5, 2017 by Carolyn Beans

Disturb fruit fly larvae with sharp jabs or intense heat and they’ll respond the same way every time. “They always roll two or three times, and then stop rolling and land away from the noxious thing,” says neuroscientist Kazuo Emoto … Continue reading →
