Here’s What Happens When You Put Camera Traps in Trees

by Elizabeth Preston in Inkfish

The world holds very few unexplored places between zero and six feet off the ground. If humans can walk right up to it and take a picture, we probably already have. But the tops of the trees, like the bottom of the ocean, are a different story. “We know so much less about arboreal mammal […]The post Here’s What Happens When You Put Camera Traps in Trees appeared first on Inkfish....

Breaking Up is Hard to Do: Photosynthesis, Water-Splitting, and the OEC

by Melissa Chernick in Science Storiented

A very very cool paper was recently published online. The paper details a study that shows the first images of water splitting apart during photosynthesis. So pick you jaw up off the table and we’ll get into the nitty-gritty details. Let’s start by accessing your long-term memory, dragging out some of that basic biology information you buried after high school and grabbing on to that dusty file about photosynthesis. If you remember, plants have little green, bean-shaped energy factories in t........ Read more »

The Pressure of the World Cup Penalty Kick

by THE 'SCOPE in The 'Scope

Tim Howard was brilliant in goal for the United States at the 2014 World Cup. Flying all over the place, catching, punching, kicking – he looked like he was protecting his family home from post-apocalyptic cannibals. It was very impressive, but the US went out against Belgium 2-1 in extra time, despite Howard’s 17 saves, the most in a single World Cup game in 50 years. Tim Howard had a great game for the US, heck, a great tournament. So great in fact, that Wikipedia temporarily&nbs........ Read more »

It's possible to "forget" unwanted habits

by Christian Jarrett in BPS Research Digest

New research shows that we can weaken and even undo practised habits by deliberately deciding to forget them.Gesine Dreisbach and Karl-Heinz Bäuml from Regensburg University first instilled new habits in their participants by presenting them with German words and training them over many trials to make the same response to each word - a left-handed key-press for half of them, a right-hand response for the remainder.Later, participants had to categorise the same words by gender, with key-presses ........

History of neuroscience: Hodgkin and Huxley

by neurosci in Neuroscientifically Challenged







Hodgkin and Huxley used the large axons of the giant squid to measure voltage changes during an action potential.






By the late 1930s, researchers had come to understand several important things about the conduction of signals within neurons. For example, they knew that signaling within neurons is electrical in nature (as opposed to signaling between neurons, which is usually chemical), and that it occurs in bursts of activity called action potentials. And th........ Read more »

16 Ancient Clovis Elephant-Hunting Camp Discovered in Mexico

by Blake de Pastino in Western Digs

Archaeologists in Mexico have discovered an ancient camp where members of the Clovis culture hunted an elephant-like animal never before seen in North America's archaeological record. What’s more, the site dates to 13,400 years ago, making it one of the oldest known Clovis sites, and the southernmost evidence yet found of the culture's reach. Read on to find out more!...

Cognitive Reserve Boosts Traumatic Brain Injury Recovery

by William Yates, M.D. in Brain Posts

Cognitive reserve (high educational attainment, high IQ) is known to reduce or delay the risk for Alzheimer's disease.However, the effect of cognitive reserve on recovery from traumatic brain injury (TBI) is less well studied.Two recent research studies support the beneficial effects of cognitive reserve on TBI.Schneider and colleagues examined a series of 769 adult TBI subjects using the TBI Model Systems Database.This cohort was followed during rehabilitation for a period of at least one year.........

Young men and women have very different attitudes towards touch in cross-sex friendships

by Christian Jarrett in BPS Research Digest

Friendships between heterosexual men and women can be tricky to navigate, especially when it comes to tactile contact. Is that touch on the arm a gesture of platonic care and affection? Or an unwanted signal of sexual interest? A new survey by US researchers shows the situation is complicated by the contrasting attitudes of young men and women towards touch in cross-sex friendships.Michael Miller and his team quizzed 276 undergrads at an Eastern US University, including 128 women*. The participa........ Read more »

Meditation may not be for epileptics

by Katharine Blackwell in Contemplating Cognition

In epilepsy, a seizure begins with just a few neurons that – for reasons that still elude medical professionals – get overstimulated. That excess stimulation then gets passed through the synapses to other neurons, which become overstimulated in turn, and the spread of that intense chaotic activity produces the behavioral features of a seizure. These disruptive bursts of activity also damage the brain, and can lead to cognitive deficits, so anyone with epilepsy will take great pains ........ Read more »

Kidney Donors and Kidney Failure – Once More, With Feeling

Here’s a recap: (emphasis mine)   Compared with controls, kidney donors had a significant 11.4 times increased risk of ESRD, 1.4 times increased risk of cardiovascular death, and 1.3 times increased risk of death from any cause, after adjusting for potential …

Would you rather be harassed or ostracized at work?

by Rita Handrich in The Jury Room

What a choice. We have written before about incivility in the workplace and that sounds a lot like what these researchers are calling ostracism. To begin, let’s look at how the researchers define both harassment and ostracism. In brief, say the researchers, harassment is the presence of an unwanted behavior and ostracism is the absence […]
