These cells produce 10-50 watts of power per m2, and could be used to laminate the windows of skyscrapers, giving them an additional source of power. Or they could be printed onto materials such as steel, meaning they could be embedded into roofs of buildings.
Over 10 days in November 1983, the U.S. and the Soviet Union nearly started a nuclear war. Now newly declassified documents reveal just how close we reached a mutual destruction -- because of an exercise.
Scientists have made an embryonic clone of a person, using DNA from that person's skin cells. In the future, such a clone could be a source of stem cells, for super-personalized therapies made from people's own DNA.
The rush to embrace and console every gay man who comes out is infantilizing and condescending — but it's a script written and promoted by GLAAD and reinforced by a sanctimonious establishment of gay men that rewards those who play by the rules — and punishes those who don't. Novelist Bret Easton Ellis on why he refuses to take his bitch-slapping lying down.
The alpha wolf is a figure that looms large in our imagination. The notion of a supreme pack leader who fought his way to dominance and reigns superior to the other wolves in his pack informs both our fiction and is how many people understand wolf behavior. But the alpha wolf doesn't exist — at least not in the wild.
In a 1968 plane crash, the US military lost an atom bomb in Greenland's Arctic ice. But this was no isolated case. Up to 50 nuclear warheads are believed to have gone missing during the Cold War, and not all of them are in unpopulated areas.
In normal times, an arithmetic mistake in an economics paper would be a complete nonevent as far as the wider world was concerned. But in April 2013, the discovery of such a mistake—actually, a coding error in a spreadsheet, coupled with several other flaws in the analysis—not only became the talk of the economics profession, but made headlines. Looking back, we might even conclude that it changed the course of policy.
The news that famous physicist Stephen Hawking has decided to join the academic boycott of Israel has attracted some heated commentary. But to better understand this controversy, it is useful to look at boycotts as a form of nonviolent action and the role of academics as activists.
Although the act of publishing seems to entail sharing your research with the world, most published papers sit behind paywalls. The journals that publish them charge thousands of dollars per subscription, putting access out of reach to all but the most minted universities.
Benoit Mandelbrot, the brilliant Polish-French-American mathematician who died in 2010, had a poet’s taste for complexity and strangeness. His genius for noticing deep links among far-flung phenomena led him to create a new branch of geometry, one that has deepened our understanding of both natural forms and patterns of human behavior. The key to it is a simple yet elusive idea, that of self-similarity.
