A new study follows dogs from neonates to adults to find out if puppy tests predict adult behaviour.Photo: Mikkel Bigandt / ShutterstockLots of people want to know if a puppy’s behaviour will tell you what it will be like as an adult dog. From people choosing a pet dog from a breeder’s litter, to organizations training service, police or military dogs, making the right choice of puppy could really help later on. But there have long been concerns that puppy personality tests don’t necessari........ Read more »

Sunflowers were named by Linnaeus for their round shape and bright color that reminded him of the sun, not because they follow the sun. But they do seem to turn to face the sun each day. A new review has looked at the molecular mechanisms that control the movement of the apex of the plant. But questions remain – how does the plant turn back to the east at night? Why is it that the flower turns but the leaves do not? Why does the movement stop when the flower matures?... Read more »

It’s always tough to measure something that seems very subjective. Like ostracism. Are you being ostracized (excluded, left out, or shunned) or are you just way too sensitive? Intrepid researchers have pushed forward though and brought us the Workplace Ostracism Scale. Ostracism is very much like incivility which is seen as very hard to objectively […]

Whilst I am always a little cautious about the use of the word 'biomarker' when applied to a heterogeneous condition like autism, even the autisms, I am nevertheless always intrigued at any reasonable prospect reported in the scientific literature.

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.

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.

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 ........

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 »
