Eternal sunshine of the unconscious mind

Thu, 12 Nov 2009 00:00:00 -0800

New Scientist - By Amanda Gefter - Nov. 12 (News Report) - On Saturday, at New York City's Rubin Museum, Academy Award-winning screenwriter Charlie Kaufman (who wrote Being John Malkovich, Eternal Sunshine of the Spotless Mind and Adaptation) and Jungian psychoanalyst John Beebe took the stage and were handed an image that neither had seen before. It depicted a figure of a man with a ray of light flowing into (or out of) his chest, and a snake, its head reared, coiled around his feet.

Expanding waistlines may cause shrinking brains

Sun, 23 Aug 2009 00:00:00 -0700

New Scientist - By Nora Schultz - Aug. 23 (Special Report) - Brain regions important for cognition are smaller in obese older people, making their brains look up to 16 years older than they are. As brain shrinkage is linked to dementia, this adds weight to the suspicion that piling on the pounds may up a person's risk of the brain condition.

Fast-spinning black holes might reveal all

Sun, 09 Aug 2009 00:00:00 -0700

New Scientist - By Marcus Chown - Aug. 09 (News Report) - It is the ultimate cosmic villain: space and time come to an abrupt end in its presence and the laws of physics break down. Now it seems a "naked" black hole may yet emerge in our universe, after spinning away its event horizon. In 1969, physicist Roger Penrose postulated that every singularity, or black hole, must be shrouded by an event horizon from which nothing, including light, can escape. His Cosmic Censorship Conjecture has it that singularities are always hidden.

Space storm alert: 90 seconds from catastrophe

Mon, 23 Mar 2009 00:00:00 -0700

New Scientist - By Michael Brooks - Mar. 23 (Special Report) - IT IS midnight on 22 September 2012 and the skies above Manhattan are filled with a flickering curtain of colourful light. Few New Yorkers have seen the aurora this far south but their fascination is short-lived. Within a few seconds, electric bulbs dim and flicker, then become unusually bright for a fleeting moment. Then all the lights in the state go out. Within 90 seconds, the entire eastern half of the US is without power.

Neutron tracks revive hopes for cold fusion

Mon, 23 Mar 2009 00:00:00 -0700

New Scientist - By Colin Barras - Mar. 23 (News Report) - Twenty years to the day that two electrochemists ignited controversy by announcing signs of cold fusion at an infamous press conference in Utah (watch a video of the 1989 event), a separate team has made a similar claim in the same US state. But this time, the evidence is being taken more seriously. Back in 1989, Martin Fleischmann and Stanley Pons at the University of Utah announced the tantalising prospect of abundant, almost-free energy, but their claims of fusion reactions in a tabletop experiment were dismissed by nuclear physicists, not least because such reactions normally occur inside stars. The few watts of extra energy they found were widely considered a fluke. Now Pamela Mosier-Boss and colleagues at Space and Naval Warfare Systems Command (SPAWAR) in San Diego, California, are claiming to have made a "significant" discovery – clear evidence of the products of cold fusion. On 23 March, the team presented its work at the American Chemical Society's spring conference in Salt Lake City, Utah, a few months after the study was published in a peer-reviewed journal (Naturwissenschaft, DOI: 10.1007/s00114-008-0449-x).

Children come with a high carbon cost

Sun, 15 Mar 2009 00:00:00 -0700

New Scientist - Mar. 15 (Special Report) - With rising future emissions, each extra child in the US would eventually result in eight times the lifetime carbon footprint of the average US resident today. Even with constant per-capita emissions, it's nearly six times - or nearly 10,000 tonnes of CO2. In the shrinking-emissions scenario, the US legacy per child would only be about 500 tonnes, roughly one-third of current lifetime emissions.

From AC to DC: Going green with supergrids

Wed, 11 Mar 2009 00:00:00 -0700

New Scientist - By David Strahan - Mar. 11 (Special Report) - DC is far more efficient: at the same voltage, it suffers much lower transmission losses than AC. This is because in a DC line the direction of the current is constant, whereas in an AC line it reverses 100 or 120 times a second. This induces small currents in the transmission line insulation, and this energy is then lost as heat. Because of this, HVDC has long enjoyed a niche role transporting large amounts of power efficiently over unusually long distances.

Earth may be entering climate change danger zone - environment

Tue, 10 Mar 2009 00:00:00 -0700

New Scientist - Mar. 10 (Special Report) - Climate scientists are trying to define the level of risk associated with future climate change – although they leave it up to others to decide how much risk is too much. Defining dangerous climate change is tricky because it begs the question "dangerous to whom?", says Joel Smith of environmental research firm Stratus Consulting in Boulder, Colorado.

Born believers: How your brain creates God

Wed, 04 Mar 2009 00:00:00 -0800

New Scientist - By Michael Brooks - Mar. 04 (Special Report) - That's not to say that the human brain has a "god module" in the same way that it has a language module that evolved specifically for acquiring language. Rather, some of the unique cognitive capacities that have made us so successful as a species also work together to create a tendency for supernatural thinking. "There's now a lot of evidence that some of the foundations for our religious beliefs are hard-wired," says Bloom.

How to survive the coming century

Wed, 25 Feb 2009 00:00:00 -0800

New Scientist - By Gaia Vince - Feb. 25 (Special Report) - ALLIGATORS basking off the English coast; a vast Brazilian desert; the mythical lost cities of Saigon, New Orleans, Venice and Mumbai; and 90 per cent of humanity vanished. Welcome to the world warmed by 4 °C. Clearly this is a vision of the future that no one wants, but it might happen. Fearing that the best efforts to curb greenhouse gas emissions may fail, or that planetary climate feedback mechanisms will accelerate warming, some scientists and economists are considering not only what this world of the future might be like, but how it could sustain a growing human population. They argue that surviving in the kinds of numbers that exist today, or even more, will be possible, but only if we use our uniquely human ingenuity to cooperate as a species to radically reorganise our world.

Biggest sand dunes set to grow as Earth warms

Wed, 25 Feb 2009 00:00:00 -0800

New Scientist - Feb. 25 (Special Report) - Warmer air increases the thickness of the boundary layer, which explains why Earth's largest dunes are found inland, in the hottest part of the desert. It also suggests that if global warming heats the planet in the right place, then dunes could get bigger.

Sun-powered device converts CO2 into fuel

Wed, 18 Feb 2009 00:00:00 -0800

New Scientist - By Jon Evans - Feb. 18 (Special Report) - Powered only by natural sunlight, an array of nanotubes is able to convert a mixture of carbon dioxide and water vapour into natural gas at unprecedented rates. Such devices offer a new way to take carbon dioxide from the atmosphere and convert it into fuel or other chemicals to cut the effect of fossil fuel emissions on global climate, says Craig Grimes, from Pennsylvania State University, whose team came up with the device.
