Evolutionary biologist Robert Dudley of ucberkeley describes his new book, “The Drunken Monkey, Why we drink and abuse alcohol” in this Q&A.
Hey recent grads, take note (and good luck)!
Is that a muddied polar bear? Actually, it’s believed to be a pizzly bear (also known as a grolar bear) - a rare hybrid between a polar bear and a grizzly bear. We chatted with ucberkeley biologist Eline Lorenzen about her work studying the genome of the polar bear in the Arctic and while she has yet to see a pizzly bear in the wild, she hopes their work looking into the polar bear genome will one day offer more insight into the pizzly. We’ll be posting a full interview with Lorenzen soon. Stay tuned!
Psychologist Dacher Keltner of the UC Berkeley found that the feeling of caring for someone in need activates the vagus nerve (the longest bundle of nerves in the human nervous system.
Making Huge Strides for Mobility
This exoskeleton, developed by UC Berkeley professor Homayoon Kazerooni and his team, helps people suffering from spinal cord injuries to walk again.
“Many paraplegics are not in a situation to afford a $100,000 device, and insurance companies don’t pay for these devices,” Kazerooni said. “Our job as engineers is to make something people can use.”
To make his exoskeleton affordable, he used the simplest possible technology: a computer and batteries in a backpack, actuators at the hips, and a pair of crutches with buttons that activate an exoskeleton that fits around the legs. The crutches provide stability, an important consideration for paraplegics navigating streets and sidewalks.
“The key is independence for these people,” he said. “I want them to get up in the morning and go to work, go to the bathroom, stand at a bar and have a beer.”
Of course, we’re wishing Betsy at UC Berkeley a happy World Turtle Day!
Maybe this kind of cardio workout is why, despite a high fat diet, polar bears don’t suffer from heart attacks or cardiac arrest?
OK, maybe not…but we are going to interview a UC Berkeley researcher today about her part in a study of polar bears. Postdoc Eline Lorenzen worked with international collaborators to compare their genome to that of the brown bear. The resulting work reveals new insight into adaptations to high-fat diet.
For polar bears, profound obesity is a benign state. We wanted to understand how they are able to cope with that.”
