Ravens and Empathy: The Role of Bystanders After Conflict

by Darcy Cowan in Skepticon

At the same time as we were learning that Vegetarians and Vegans might be more empathic than Omnivores we were also discovering the nature of empathy in Ravens. Published in PLoS One recently was a paper called “Do Ravens Show Consolation? Responses to Distressed Others” looking at the behaviour of Ravens and the implications for [...]... Read more »

Pouring Oil on ‘Troubled Waters’

by Kevin Zelnio in Deep Sea News

We love getting interesting emails from our readers. Some are complaints about our (mostly mine) colorful language, many are emails telling us how they appreciate what we do, several even come from our colleagues who would like us to know about some recent research or a new expedition, and we get many readers asking us specific . . . → Read More: Pouring Oil on ‘Troubled Waters’...

Cocaine, Cannabis and Sleep Architecture

by William Yates, M.D. in Brain Posts

By Hannah Dunbar(Brain Post Note: Hannah Dunbar is a summer research student who attends Oral Roberts University. She is providing some guest posts on her topic of interest--sleep in bipolar disorder). Bipolar disorder commonly is complicated by concurrent illicit substance abuse. Since drugs of abuse have their own effects on sleep it is important to understand these effects. We will review the effects of cocaine and cannabis on sleep. Sleep effects of drugs may be quite different during a........ Read more »

Will Nano-Publications & Triplets Replace The Classic Journal Articles?

by Laika in Laika's Medliblog

“Libraries and journals articles as we know them will cease to exists” said Barend Mons at the symposium in honor of our Library 25th Anniversary (June 3rd). “Possibly we will have another kind of party in another 25 years”…. he continued, grinning. What he had to say the next half hour intrigued me. And although [...]... Read more »

Neurogenesis: Learning & Memory

by neurobites in Neurobites

Hi everyone! Rim here, so sorry for the late update guys! World Cup fever! Priorities priorities. We were introduced to neurogenesis a couple of blogs ago. The birth of neurons in the adult brain has opened the floodgates to a broad range of topics for researchers. One of the most dominant types, are those who [...]... Read more »

Razor-sharp teeth and venom: The bacteria love it

by Zen Faulkes in NeuroDojo

A bite from a Komodo dragon would take you down. They have large teeth that are very sharp. And their salivary glands secrete venom.

For a long time, people sort of overlooked those two factors. The teeth were obvious, but the venom wasn’t. Instead, people suggested that one of the ways that the slow moving monitor lizards were able to take down large prey was because their mouths contained so many bacteria, that the bitten prey animal got infected, quite quickly, and went down from the bacte........

Inevitability and Oil, Pt. 1: the inherent risk for accidents in complex technology

by Hannah Waters in Culturing Science – biology as relevant to us earthly beings

When I read updates on blogs or the news about the BP oil spill, my expression is generally very serious: furrowed brow, pursed lips which I’m probably chewing in alternation with gnawing a nail.  But last week I laughed out loud, a true LOL, a brash guffaw.  (“What?!” my labmates inquired.) I had read this [...]... Read more »

Vampire bats care little for sweet blood

by Lucas in thoughtomics

This is the first blogpost in a continuing series on “sensible evolution‘: how our senses evolved and shape the way we see the world. We perceive everything that we can see and feel as ‘real’, but we know that our human senses only capture a tiny part of the natural world. There are [...]... Read more »

Watching Individual Atoms Make a Phase Transition

by Chad Orzel in Uncertain Principles

A press release from Harvard caught my eye last week, announcing results from Markus Greiner's group that were, according to the release, published in Science. The press release seems to have gotten the date wrong, though-- the article didn't appear in Science last week. It is, however, available on the arxiv, so you get the ResearchBlogging for the free version a few days before you can pay an exorbitant amount to read it in the journal.

The title of the paper is "Probing the Superfluid to Mot........ Read more »

Horns, Clubs, Plates and Spikes: How Did They Evolve?

by Brian Switek in Dinosaur Tracking

As a group, dinosaurs were certainly well-ornamented animals. Horns, spikes, crests, plates, sails, clubs and other strange structures marked the bodies of many dinosaurs, but figuring out why these dinosaurs had these structures in the first place has often been difficult to figure out. Numerous hypotheses for different structures have been proposed over the years. [...]... Read more »

Homo sapiens can bite hard, after all

by Laelaps in Laelaps

Three-dimensional models of hominoid skulls used in the study - (a) Hylobates lar; (b) Pongo pygmaeus; (c) Pan troglodytes; (d) Gorilla gorilla; (e) Australopithecus africanus; (f ) Paranthropus boisei; (g) Homo sapiens. They have been scaled to the same surface area, and the colors denote areas of stress (blue = minimal stress, pink = high stress). From Wroe et al, 2010.

It is all too easy to think of human evolution in linear terms. From our 21st century vantage point we can look back thro........ Read more »

Modeling the Body’s Micro Machines

by Rob Mitchum in ScienceLife

Inside the human body are millions of miniature machines, the gatekeepers of the electrical impulses that keep our hearts beating and our minds thinking. They’re called ion channels; portals that allow small ions such as sodium, potassium, calcium, and chloride, to pass in or out of cells. A simple responsibility, with a complex and crucial [...]...

Standardized Time and Power Relations

by Krystal D'Costa in Anthropology in Practice

Whose Time do we live in? Time zones have set standards in keeping with longitudinal boundaries so that we share a clock experience that is often managed by an urban center. I am not the first to note, however, that these standards of Time overlook local, social definitions of Time. Though these local definitions persist, they are not generally the norm adhered to when individuals interact both

Goal Setting – Pitfalls and Benefits

by Shaheen Lakhan in Brain Blogger

Goal setting is a funny thing. Like many of you, I’m sure, I’ve had a long and checkered relationship with it. I’ve gone back and forth, was a big fan, hated it, went back to goal setting again. What is it that fascinates and repels about goal setting? I set out to look at some [...]... Read more »

Palaeolithic and Mesolithic archaeology in Switzerland – where we stand now

by M. Cornelissen in hazelnut relations

As usual, the 2010 Jahrbuch Archäologie Schweiz vol. 93 includes a list of newly discovered and excavated sites. It is no surprise that the number of Palaeolithic and Mesolithic sites discovered or investigated in 2009 is relatively low in comparison to the number of sites from most later prehistoric, roman and medieval periods. The figure [...]... Read more »

Does Melatonin Have a Role in Energy Regulation?

by Arya M. Sharma in Dr. Sharma's Obesity Notes

Regular readers of these pages will recall previous articles on the discoveryof brown adipose tissue in adult humans.
Brown adipose tissue or BAT is specifically designed to turn calories into heat, thereby significantly affecting metabolic rate.
The current theory is that people who have more BAT, are more obesity resistant and can better handle excess calories. It [...]... Read more »
