The leap second may live on for at least another three years. Once or twice a year, the leap second can be tacked on to synchronize atomic clocks — the world’s scientific timekeepers — with the Earth’s rotational cycle, which does not run quite like clockwork. Without the leap second, atomic clocks would diverge about…
The search for the perfect alliance between science and technology has married quantum computing to the future of IT – the cloud. Researchers have used quantum mechanics to encrypt heavy-duty number-crunching computing, thereby removing a major obstacle in the adoption of the cloud for many enterprises – how safe is my data when it’s hosted…
Scientists in a cluttered Berkeley laboratory are working a bit of biochemical wizardry to transform ordinary seaweed into biofuels that promise a new source of energy for this oil-dependent nation. The lab’s research has already fueled a start-up company whose workers at a coastal site in southern Chile are farming nearly 200 acres of kelp…
Why does our universe look the way it does? In particular, why do we only experience three spatial dimensions in our universe, when superstring theory, for instance, claims that there are ten dimensions — nine spatial dimensions and a tenth dimension of time? Japanese scientists think they may have an explanation for how a three-dimensional universe emerged…
What existed before the big bang? What is the nature of time? Is our universe one of many? On the big questions science cannot (yet?) answer, a new crop of philosophers are trying to provide answers. Stephen Hawking may have famously declared that “Philosophy is dead.” but philosopher of physics Tim Maudlin disagrees. Maudlin, whose…
At the end of the Cretaceous period some 65 million years ago, an asteroid slammed into Mexico’s Yucatan Peninsula, causing severe but selective extinction. While that is widely accepted, it has remained unclear exactly what the mechanisms were that caused extinction of ocean-dwelling organisms. Proposed explanations include global darkness due to blocking of sunlight with…
A team of astronomers has identified a new galaxy that may be made completely of dark matter, the second of its kind. In a discovery announced in January, an international team of researchers has found a dark dwarf galaxy about 10 billion light years from Earth. In the current issue of Nature, the team of…
The Amazon rainforest is in flux, thanks to agricultural expansion and climate change. In other words, humans have “become important agents of disturbance in the Amazon Basin,” as an international consortium of scientists wrote in a review of the state of the science on the world’s largest rainforest published in the journal Nature. The dry…
Like all of us, economist Tyler Cowen loves a good story. But in this intriguing talk from TEDxMidAtlantic, he asks us to step away from thinking of our lives—and our messy, complicated irrational world—in terms of a simple narrative.
The man behind the popular 2008 documentary Food, Inc. is out with a new project aimed at getting the U.S. Food and Drug Administration (FDA) to label genetically engineered or modified (GE or GMO) food products. Filmmaker Robert Kenner’s “Labels Matter” piece is part of his FixFood project, a social media platform to empower Americans…
