The 2015 U.S. Tennis Open is in full swing and I ran into an interesting recent manuscript summarizing fatigue in tennis.Fatigue has multiple elements including changes in muscle performance, blood markers of lactic acid and other compounds as well as brain central perception factors.Long multi-set matches can last four or five hours. Obviously, at the end of this type of exertion, players have had to adjust to effects of significant fatigue.Reid and Duffield review the key elements of fatigue i........ Read more »

The ENCODE project began many years ago, with a pilot phase, that examined just 1% of the human genome. But this initial exploration helped the consortium participants to iron out some of the directions for later stages–including focusing on specific cell lines, techniques, and technologies in Phase 2. There have been a number of publications […]... Read more »

After the Great Earthquake in Japan, preparation was key to evacuating with pets - including training and socialization.When the magnitude 9 earthquake struck Japan in 2011, causing a tsunami and subsequent accident at the Fukushima nuclear plant, over 15,000 people were killed. Many people had to evacuate at short notice. In 2012, pet owners from two of the most badly affected areas, Iwate and Fukushima Prefectures, were asked about whether or not they took their pet and the types of planning t........ Read more »

Spies try to look boring, but in reality they are much more interesting than the average Joe. So it is with dizygotic twins; monozygotic twins (“identical”) get all the glory, but they’re just a split egg, any female can do it. But dizygotic twins – certain families have more, Nigerian women have more, older women have more, taller women and overweight women have more. Now there’s something that looks boring but must be interesting.... Read more »

I was intrigued by the results reported by Catherine Best and colleagues  recently and the suggestion that yet another sweeping generalisation attributed to autism (or at least autistic traits) might turn out to be not as accurate or universal as we might have all been led to believe.Based on the analysis of data from over 300 people who completed an on-line questionnaire (anonymously) measuring autistic traits, researchers reported that creative ideas as measured by a divergent thinking task........

Everyone dreams - even people who believe that they "never dream" and can't remember any of their dreams. That's according to a group of French researchers writing in the Journal of Sleep Research: Evidence that non-dreamers do dream.
In questionnaire surveys, up to 6.5% of people report that they 'never dream'. Although most of these people report having dreamed at some point in the past, roughly 1 in every 250 people say that they can't remember ever dreaming - not even once.

What makes someone better at switching between different tasks? Looking for the mechanisms behind cognitive flexibility, researchers have used brain scans to shed new light on this question. By studying networks of activity in the brain’s frontal cortex, a region associated with control over thoughts and actions, the researchers have shown that the degree to which these networks reconfigure themselves while switching from task to task predicts people’s cognitive flexibility....

Mary Poppins taught us that a spoonful of sugar makes the medicine go down. A bumblebee's favorite sugary drink may already be laced with medicine. And bees seem to dose themselves with medicinal nectar when they're suffering from a gut full of parasites.

The process of embryo implantation consists of multiple steps: blastocyst apposition, adhesion to uterine luminal epithelial (LE) cells, and removal of the epithelial cells encasing the blastocysts. How the blastocyst trophectoderm breaches the luminal epithelial barrier has been studied for decades, the mechanism of the abstraction of LE cells was not clearly understood. Since the[...]

Sodium formaldehyde sulfoxylate, a small sulfur-containing molecule with a propensity to give away its electrons (i.e. a strong reducing agent), has many names and many uses. One of its aliases, rongalite, comes from “rongeage", a French word meaning discharge. It refers to the industrial use of the molecule as a bleaching agent to remove colour from textiles (e.g. to create a white design on a dyed background) and other materials (e.g. to clear up discoloured sugar juice squeezed from plants)........
