A hyena's LOL contains important information about itself

by Laelaps in Laelaps

Spotted hyenas giggling over an antelope spine. Courtesy BMC Ecology.

For spotted hyenas, a laugh can speak volumes about an individual.

Despite being portrayed as stupid scavengers who rely on the leftovers of lion prides, hyenas are highly intelligent and social predators. They communicate with each other through an array of whoops, yowls, grunts, screams, and giggles, and by using these calls an individual can call in help to run lions off a carcass or signal that it's time to beat a ........

Be Mindful to Maintain Job Satisfaction

by Shaheen Lakhan in Brain Blogger

Physician burnout and job dissatisfaction are concerning as physicians in the United States have more patients to see in less time with fewer resources. Physician burnout is associated with job absenteeism, leaving the profession altogether, poor quality of care, and medical errors. Now, a recent study published in the Journal of the American Medical Association [...]... Read more »

Sparkling Water Saves Lives!

by Michael Ash in Nutri-Link Ltd - Clinical Education

Michael Ash BSc(Hons) DO, ND, Dip ION explores the idea that drinking sparkling water has a direct health benefit for the drinker, if not for the environment.
In this case fizzy drink consumers are directed towards a specific water drink rather than some of the more challenging sugar laden carbonated offerings. So if compelled to drink [...]... Read more »

Dopamine and Obesity: The Food Addiction?

by Evil Monkey in Neurotopia

Sci picked this paper today partially because it was handed to her on a platter by the fantastic Dr. Pal, and partially because today she is SO HUNGRY. She's had a TON of food already today, and is still entirely ravenous. Maybe it was looking at this paper too long.

As I'm sure most of y'all out there are aware, obesity is a problem in the US. No one is sure whether it's due to increased portion size, increased availability, decreased physical activity, changes in g........ Read more »

Climate change and philosophy of science: Does climate science aim at truth?

by Michael Slezak in Good, Bad, and Bogus

A couple of weeks ago there was an interesting exchange in The Guardian between George Monbiot and Nicholas Maxwell, a philosopher of science from University College London. In his piece, Monbiot presents an excellent, if overly pessimistic, analysis of the psychology behind climate change denial. In his response, Maxwell draws on some interesting results from the philosophy [...]... Read more »

What causes scientifc misconduct?

by Janet D. Stemwedel in Adventures in Ethics and Science (Sb)

In the last post, we looked at a piece of research on how easy it is to clean up the scientific literature in the wake of retractions or corrections prompted by researcher misconduct in published articles. Not surprisingly, in the comments on that post there was some speculation about what prompts researchers to commit scientific misconduct in the first place.

As it happens, I've been reading a paper by Mark S. Davis, Michelle Riske-Morris, and Sebastian R. Diaz, titled "Causal Factors ........ Read more »

Photosynthesis in frog foam

The worms go in, the worms go out: The habits of prehistoric, bone-eating worms

by Laelaps in Laelaps

The fail whale comes to rest; the decomposing body of a gray whale is host to a diverse array of scavengers and other deep sea organisms. From Goffredi et al., 2004.

In the deep sea, no carcass goes to waste. Platoons of crabs, fish, and other scavengers make short work of most of the bodies which come to rest on the sea bottom, but every now and then the carrion-eaters are presented with a rotting bonanza; a whale fall. Muscle, viscera, blubber, and bone; it all gets broken down, but it t........ Read more »
