Yellow gets greener in summer

Guardian Science - Mon, 2015-08-24 21:30

Remember winter, when everything was cold and grey? Right now, when all around is lush and green, the contrast couldn’t be greater. But is everything really as it seems? New research shows that we see things differently in winter compared with summer.

Our eyes perceive four pure, unmixed colours – blue, green, red and yellow. People often find it hard to agree exactly what shade pure blue, green and red are, but curiously we tend to see pure yellow the same way, despite having different eyes. Lauren Welbourne, a psychologist at the University of York, wondered if that was because yellow is influenced more by the world around us than the biology of our eyes.

Great Barrier Reef species more at risk from climate change, says study

Guardian Science - Mon, 2015-08-24 21:23

Tropical species with smaller geographical ranges are more likely to die out in a warming climate than those that can adapt by ‘invading’ new regions

Species native to the Great Barrier Reef are more likely to face extinction through climate change than marine life elsewhere that can adapt by “invading” new regions, according to new research.

The largest study to date on the impacts of climate change on marine biodiversity found that many species would cope by finding new waters.

Gladstone collars, Anthony Eden hats, Wilson’s raincoats – now it’s Jeremy Corbyn vests. Why are male politicians judged by their clothing rather than their policies and principles?

Going Viral: scientific storytelling with contagious ideas

Guardian Science - Mon, 2015-08-24 18:13

Talking to Daniel Bye about his Fringe First-winning performance lecture throws up some interesting ideas about the interaction between science and society

“I’d say it’s quite funny for about the first 5 mins then rapidly downhill “, says Daniel Bye of his Fringe First-winning Edinburgh show, Going Viral. “There are more laughs in it later on, but it is quite a bleak view of the world, or rather, a view which is bleak. Well. That’s really going to make people want to see it.”

It might sound less attractive than a hazmat suit, but if you’re at all interested in science and ideas you should catch it.

Universal flu vaccine a step closer as scientists create experimental jabs

Guardian Science - Mon, 2015-08-24 16:53

Annual vaccinations could be a thing of the past as scientists have successfully tested vaccines on animals infected with different strains of influenza

A universal flu vaccine that protects against multiple strains of the virus is a step closer after scientists created experimental jabs that work in animals.

The vaccines prevented deaths or reduced symptoms in mice, ferrets and monkeys infected with different types of flu, raising hopes for a reliable alternative to the seasonal vaccine.

Look into my eyes: can 10 minutes of staring make you hallucinate?

Guardian Science - Mon, 2015-08-24 16:39

Gaze adoringly at your loved one, and they will soon look deformed, monstrous or like your mother, according to a study. One writer puts it to the test

The first two minutes are the trickiest. My partner, C, and I are seated opposite one another in our bedroom, staring into each other’s eyes. As she does every single morning after finishing her breakfast, our dog saunters in and burps resonantly, as close to our faces as she can aim. We burst into laughter but do not break eye contact. Only another eight minutes to go …

We’re doing something we’ve never done in our 11 years together: looking into each other’s eyes without pausing, smiling or talking for 10 minutes. No, this is not some Relate-endorsed attempt to save our relationship, though I wouldn’t put it past C, who has just qualified as a Gestalt therapist and does this sort of thing for larks, to suggest it. “Ten minutes?” she splutters when I instruct her to come home immediately and look into my eyes. “Last time I did it, it was only four and I was in love with the man by the end!”

Want to read this article later? Maybe you should just print it out | Oliver Burkeman

Guardian Science - Mon, 2015-08-24 16:17

It’s becoming increasingly difficult to keep track of online reading material. That’s why physical print-outs sometimes trump a digital copies

I’ve spent many, many hours – I’m sure most people would say too many hours – devising geeky personal systems for managing information in the digital era. For example, I’ve reached certain conclusions about how to deal with email overload; how to manage your to-do list; or how to resist the distractions of social media. And fortunately, because I’m a journalist, I have an excuse to tell you about them, whereas otherwise I’d just be that appallingly tedious guy at social events who won’t stop telling you about his favorite lifehacks. (To be clear, I am also that guy, but this needn’t concern us here.)

Still, there’s one big challenge I’ve never been able to master: how to keep track of all the interesting reading-matter I encounter online, or in ebooks, and then how to store and usefully refer to the notes I make on it. If you’ve had 27 tabs open in Chrome for the last four months, or 322 bookmarks in Firefox, or if you habitually highlight passages on your Kindle then promptly forget all about them, you’ll know what I mean.

Ashley Madison hack: do victims deserve to be punished? | Girl on the Net

Guardian Science - Mon, 2015-08-24 12:15

A recent article stated that (male) victims of the Ashley Madison hack deserve their fate. Real life, however, is far from being so clear cut.

I’ve heard a lot of gloating in the light of the Ashley Madison hack - most of it along the lines that the cheaters on the site deserved to be outed because cheating on your partner is an awful thing to do. It was only today that I saw the first solid ground laid for the “well they shouldn’t have been so stupid” argument.

Yesterday, Barbara Ellen explained that she isn’t sorry for any of the men who were exposed in the Ashley Madison hack because they were just plain stupid:

Heroes, monsters and people: When it comes to moral choices, outstanding physicists are very ordinary

Guardian Science - Mon, 2015-08-24 08:26

Did German physicists have a plan in the 1930s? And if so, was their physics any help?

Last week, on the plane back from Chicago, I finished Philip Ball’s book about physics in Germany in the nineteen-thirties and -forties. I’m still thinking about it, and I’m trying to work out why it has left such a strong impression. I think it is because the compromises, recriminations and judgements formed have echoes, weak but clear, in so many other arguments going on today.

It is difficult to be nuanced about Nazis. There are obvious reasons for this, but it is nevertheless sometimes important to try. That genocidal ideology came from somewhere, and looking back on the period through a lens which colours everyone as hero or monster is not necessarily helpful for gaining understanding, and therefore not necessarily a good approach to the prevention of such abominations in future.

Why the secrecy, Mr Javid? Tell us more about the McKinsey review

Guardian Science - Mon, 2015-08-24 07:36

Despite a freedom of information request, the Department for Business, Innovation and Skills refuses to share details of the funding review it has commissioned from the consultancy McKinsey.

Openness and transparency can save money, strengthen people’s trust in government and encourage greater public participation in decision-making. Or so says the website. But that doesn’t seem to be the modus operandi in Sajid Javid’s Department for Business, Innovation and Skills (BIS).

Over the summer, rumours have been swirling (first published by the Guardian’s Political Science blog) that the consultants McKinsey & Company have been called in by BIS to advise where cuts could be made to the department’s budget, which includes £4.7 billion of annual investment in science, research and innovation. This is an internal review, and hasn’t been officially announced, but we understand it is due to report in early September, in time to inform spending review negotiations.

Why does going to the dentist feel like a trip back in time to the stone age?

Guardian Science - Sun, 2015-08-23 10:00
In this era of hi-tech surgery and medical innovation, dentistry can feel a little left behind. But is this fair, or just an image problem?

Who among us hasn’t had this thought, as a dentist industriously and cheerfully chisels and scrapes and drills away at your teeth: surely there is a better way?

When anthropologists last month discovered evidence of dental handiwork in a 14,000-year-old tooth, the surprising thing about it wasn’t the fact that people in the stone age had cavities and tried to do something about them. It was the fact that the procedure seemed so … familiar.

IVF availability ‘allows women to delay having babies and pursue careers’

Guardian Science - Sat, 2015-08-22 22:24

Access to fertility treatment encourages more education and career planning, says a study looking at Israel, where IVF has been free to all citizens since 1994

Women who live in countries where IVF is widely available are more likely to delay the key events in their personal lives so that they can focus on building their careers.

New research suggests that women with ready access to IVF are more likely to marry, to complete their university education and to pursue postgraduate qualifications later on in their lives.
