How scientifically accurate is The Martian?

Guardian Science - Tue, 2015-10-06 12:27

The release of Ridley Scott’s space hit coincided with the discovery of water on the red planet, which leads us to ask – how realistic is it, technically? A leading aerospace engineer offers his opinion

Overall it’s a very good movie, and while there are mistakes in it, it is the first genuine Mars movie. It is the first movie that attempts to be realistic and that is actually about human beings grappling with the problems of exploring Mars, as opposed to various movies set on Mars that are essentially either shoot ’em ups or horror films. It does not engage in fantasy: no monsters, no magic, no Nazis. However, there are a number of technical mistakes.

Dementia scientists are leaving the field in droves – we need to keep them

Guardian Science - Tue, 2015-10-06 12:00

Dementia is now a government priority but 70% of researchers leave four years after their PhD. We need to improve the career path before its too late

Dementia is in the public and political spotlight like never before, as society wakes up to the fact that it poses one of the greatest threats to the health and wealth of our country.

The numbers are stark: 850,000 people in the UK are currently living with dementia, at an estimated cost of more than £26bn a year. By 2021, one million people will have the condition.

Nobel prize for physics won by Takaaki Kajita and Arthur McDonald - as it happened

Guardian Science - Tue, 2015-10-06 11:56

Results and reaction as it happened for second of this week’s three top science prizes. It went to the Japanese and Canadian scientists for their work to reveal how neutrinos – elusive subatomic particles – change identities or ‘flavours’, and expand our understanding of the innermost workings of matter and the universe

Which are the best world university rankings in the world?

Guardian Science - Tue, 2015-10-06 11:00

Last week saw the publication of the latest world university rankings. But until the purveyors of these league tables address the uncertainties in their data, no-one knows where they really stand

The Times Higher Education World University Rankings were announced last week to much fanfare, at least in certain corners of academia. They were “bigger, better and more comprehensive”, according to their editor, Phil Baty.

Such ranking exercises are a big and growing industry. This year the Times Higher has assessed 800 institutions, double the number considered last year. And their ranking is now one only one of at least ten different schemes for grading the world’s universities. No institution wishing to compete globally – or even nationally – can afford to ignore them.

UN delay could open door to robot wars, say experts

Guardian Science - Tue, 2015-10-06 06:00

Observers say UK and US are seeking to water down agreement so that any autonomous weapons deployed before talks conclude will be beyond reach of ban

The United Nations has been warned that its protracted negotiations over the future of lethal autonomous weapons – or “killer robots” – are moving too slowly to stop robot wars becoming a reality.

Lobbying for a pre-emptive ban on the weapons is intensifying at the UN general assembly in New York, but a deal may not emerge quickly enough to prevent devices from being deployed, experts say.

What happened to wildlife when Chernobyl drove humans out? It thrived | @GrrlScientist

Guardian Science - Mon, 2015-10-05 18:08

People were evacuated after the Chernobyl accident, but what happened to the local wildlife? A new study shows that wildlife in the Chernobyl disaster zone is thriving, indicating that the presence of humans is more damaging to wildlife than is radiation poisoning

After a fire and explosion destroyed the Chernobyl Nuclear Power Plant in 1986, more than 100,000 people were permanently evacuated from the area to avoid radiation levels that were twenty times greater than the Hiroshima and Nagasaki bombings. But what happened to the local wildlife? According to a letter published today in the journal, Current Biology, scientists report that the Chernobyl disaster area is home to a rich and varied wildlife community, indicating that the mere presence of people is more damaging to wildlife than is radiation poisoning.

Illegal trade is causing shocking decline in plants that are vital to desert ecosystems, most comprehensive global assessment yet reveals

Nearly a third of the world’s cacti are facing the threat of extinction, according to a shocking global assessment of the effects that illegal trade and other human activities are having on the species.

Cacti are a critical provider of food and water to desert wildlife ranging from coyotes and deer to lizards, tortoises, bats and hummingbirds, and these fauna spread the plants’ seeds in return.
