Nature’s GPS:  It’s Not As Batty As You Think!

Nature’s GPS: It’s Not As Batty As You Think!

Researchers at the Weizmann Institute of Science used an Epyptian-fruit-bat model to study the brain’s representation of navigation from Point A to Point B. Their work on how the bat brain handles goal-focused navigation could affect how we will one day treat Alzheimer’s.

Q&A: Why Do Killer Whales Go Through Menopause?

Q&A: Why Do Killer Whales Go Through Menopause?

Why do some species, including humans and killer whales, stop reproducing long before the end of their lives? A new study from Exeter University suggests that older females may gain adaptive advantages by helping to raise their daughters’ calves instead of raising their own.

The Powerpuff Sponges: Sea sponges solve problems in structural engineering

The Powerpuff Sponges: Sea sponges solve problems in structural engineering

Deceptively flimsy, sea sponges may just be the key to stronger and more effective material design. Michael Monn and Haneesh Kesari investigated the structure properties of the rod-like spicules that give the sponges their shape and found that their tapered shape makes them 33% less likely to buckle under pressure.

Modern Animals with Ancient Genes: Testing the causes of evolution

Modern Animals with Ancient Genes: Testing the causes of evolution

It was once thought fruit flies can process more alcohol than their sister species because of a difference in their genome. Now, a collaboration between evolutionary and molecular biologists is challenging this hypothesis by putting ancient genes in modern fruit flies

A Rocky Road to the Past: Scientists Discover Trends in Long-Term Climate Change

A Rocky Road to the Past: Scientists Discover Trends in Long-Term Climate Change

Using new analytics to understand tiny mineral crystals, a Yale G&G team has discovered evidence for the effect of volcanic activities on global climate. Because the zircon crystals that were investigated have a particularly long lifetime, this innovative technique carries potential for the future of climate change research.
