Are Works Of Art Relics?

"Untitled" by Mark Rothko, on display before auction at Sotheby's, New York, in May. Does its value stem from its pedigree? Or is it valuable because of its contribution to the ongoing dialog that is human expression through the ages?

In an essay just published in The Brooklyn Rail, NYU art historian Alexander Nagel argues that it's time to move beyond the relic-cult model of artworks that, he believes, has influenced our attitudes to art since about 1700.

When It Comes To Thinking, 2 Fish Heads Are Better Than 1

Originally published on Fri July 18, 2014 11:52 am

Maybe we can learn from fish — they don't call a group of them a school for nothing. Researchers found that when 2 fish swim together, they make better decisions than when 2 fish are swimming alone.

Sizing Down Food Waste: What's The Worst Thing To Toss?

Originally published on Thu July 17, 2014 7:11 pm

Throwing out a pound of boneless beef effectively wastes 24 times more calories than throwing out a pound of vegetables or grains. Egg and dairy products fall somewhere between the two extremes.
Morgan Walker NPR

Sometimes I feel like a broken record at home: "Let's eat the leftovers for dinner, so they don't go to waste,"

But inevitably, Sunday night's pasta and meatballs get tossed out of the refrigerator to make way for Friday night's pizza.

Now scientists at the University of Minnesota offer up another reason to put those leftover meatballs in the tummy instead of the garbage: There are hidden calories in the beef that go to waste when you toss it.

To Make A Spacecraft That Folds And Unfolds, Try Origami

Originally published on Thu July 17, 2014 8:40 pm

Scientists and engineers at NASA are using origami techniques to help solve a fundamental dilemma facing spacecraft designers: How do you take a big object, pack it into a small container for rocket launch, and then unpack it again once it arrives in space — making sure nothing breaks in the process.

Young Scientists Say They're Sexually Abused In The Field

Originally published on Tue July 22, 2014 3:44 pm

Many young scientists dream of their first trip to a remote research site — who wouldn't want to hang out with chimps like Jane Goodall, or sail to the Galapagos like Charles Darwin, exploring the world and advancing science?

But for many scientists, field research can endanger their health and safety.

In a survey of scientists engaged in field research, the majority — 64 percent — said they had personally experienced sexual harassment while at a field site, and 22 percent reported being the victim of sexual assault.

Australia became the first country in the world to repeal a carbon tax on the nation's worst greenhouse gas polluters, as Prime Minister Tony Abbott made good on a campaign promise to get rid of the unpopular law.

The Senate voted 39 to 32 to eliminate the tax enacted by the previous center-left government two years ago. The law imposed the equivalent of a $22.60 tax per metric ton of carbon dioxide emissions on about 350 of the nation's worst polluters.

Physicists have used the world's most powerful laser to zap diamonds. The results, they say, could tell us more about the cores of giant planets.

"Diamonds have very special properties, besides being very expensive and used for jewelrey etc.," says Raymond Smith, a researcher at Lawrence Livermore National Laboratory in California. "It's the hardest substance known to man."
