Managers have bigger brains. The study found a clear relationship between the number of employees a person may have supervised or been responsible for and the size of the hippocampus.

UNSW researchers have, for the first time, identified a clear link between managerial experience throughout a person’s working life and the integrity and larger size of an individual’s hippocampus – the area of the brain responsible for learning and memory – at the age of 80. The findings refine our understanding of how staying mentally active promotes brain health, potentially warding off neurodegenerative diseases such as Alzheimer’s. The study was presented at the Brain Sciences UNSW symposium Brain Plasticity –The Adaptable Brain today. Editor's Note: Original news release can be found here.

This post is syndicated from Open Parachute » SciBlogs – Original Post Creationists have far less influence in New Zealand than they do in the US.
Still, quite a large proportion of Christians here do not accept evolutionary science. So, I imagine, their wish to undermine the teaching of evolutionary science sometimes becomes an issue, for some teachers. Here’s a couple of videos prepared by the US National Center for Science Education (NCSE) which does a great job in the US. They are of a talk given by NCSE programs and policy director Steve Newton to an audience of high school teachers from across the US. Steve covers questions like: What challenges do biology teachers face from creationists? Teaching evolution in a climate of science denial, Part 1. Part 2: Teaching evolution in a climate of science denial, Part 2. See also: NCSE YouTube Channel Similar articles. Computer modelling of aircraft boarding.
I love this article I came across on the BBC website this weekend.
As someone who’s travelled on a lot of planes, I can fully understand the motivation to study methods of boarding a plane. Traditionally, boarding is done in this sequence: 1. Those needing special assistance (e.g. those for whom walking is difficult) Carl Sagan – Science Communicator Extraordinaire. I’ve just been reading a biography about Carl Sagan by Ray Spangenburg and Kit Moser.
It is a fascinating story and gives some insight into his fantastic ability to communicate science. In my opinion, Dr Sagan was the most powerful science communicator of the 20th century (though David Attenborough would be a close second). What is Your Favourite Sagan Quote?

Kiwis out to revolutionise research with online science marketplace. By Esther Goh, Two Kiwis are behind what has been dubbed an 'eBay for science', a website that connects scientists to other institutions with the equipment and means to carry out experiments that their own universities do not have.
Science Exchange, which launched last month, was founded by Elizabeth Iorns, Dan Knox and Ryan Abbott in April. Ten researchers awarded Rutherford Discovery Fellowships « Media Releases « News. Ten top researchers have been awarded highly sought after fellowships to help them develop their research careers in New Zealand.
The Rutherford Discovery Fellowships will provide financial support of $160,000 to $200,000 per year to these researchers over a five-year period. This funding goes towards both their salary and programme of work. The scheme was set up by the Government last year and this is the second year fellowships have been awarded. These researchers will receive funding totalling more than $8 million over the next five years.
Scientists Perceive NASA Bias Against Venus. By Eric Hand and Nature magazine Venus would seem to be a tempting destination for planetary probes: conveniently close, and an extreme laboratory for atmospheric processes familiar on Earth.
So why won't NASA send a mission there? That was the frustrated question coming from scientists at the annual meeting of NASA's Venus Exploration Analysis Group (VEXAG) near Washington, D.C., on August 30-31. Wanted: astronauts for missions unknown - space - 07 September 2011. What should NASA do with its astronaut corps now that the shuttle has been retired?
Expand it, says a new report. Even though NASA's long-term plans are uncertain, the report says adding astronauts would aid the development of new spaceships and minimise health problems arising from long and repeated stays on the International Space Station.

World's smallest electric motor made from a single molecule. Chemists at Tufts University's School of Arts and Sciences have developed the world's first single molecule electric motor, a development that may potentially create a new class of devices that could be used in applications ranging from medicine to engineering. In research published online September 4 in Nature Nanotechnology, the Tufts team reports an electric motor that measures a mere 1 nanometer across, groundbreaking work considering that the current world record is a 200 nanometer motor. A single strand of human hair is about 60,000 nanometers wide.
According to E. Charles H. Sykes, Ph.D., associate professor of chemistry at Tufts and senior author on the paper, the team plans to submit the Tufts-built electric motor to Guinness World Records. Domino's plans pizza on the Moon.
