Weather Supercomputer Used To Predict Climate Change Is One Of Britain's Worst Polluters

The computer used 1.2 megawatts to run - enough to power 1,000 homes

From The Daily Mail:

The Met Office has caused a storm of controversy after it was revealed their £30million supercomputer designed to predict climate change is one of Britain's worst polluters.

The massive machine - the UK's most powerful computer with a whopping 15 million megabytes of memory - was installed in the Met Office's headquarters in Exeter, Devon.

It is capable of 1,000 billion calculations every second to feed data to 400 scientists and uses 1.2 megawatts of energy to run - enough to power more than 1,000 homes.

Climate Change 'To Cost More Than £300 Billion'

Oxfam staged an underwater family to highlight the risk of sea rises due to climate change.

From The Telegraph:

The world will have to spend £300 billion, three times as much as previously thought, adapting to the effects of climate change, scientists have said.

The UN originally said it would cost just £25 to £105 billion ($40-170 billion), or the cost of about three Olympic Games per year, from 2030 to pay for the sea defences, increase in deaths and damage to infrastructure caused by global warming.

However a new study by leading scientific body the International Institute for Environment and Development and the Grantham Institute for Climate Change at Imperial College London estimated it will cost more than triple that amount per annum.

Laughing Gas Is Biggest Threat To Ozone

From The Telegraph:

It's no joke - laughing gas is now the biggest threat to the Earth's ozone layer, scientists have said.

Nitrous oxide, better known as the dental anaesthetic "laughing gas", has replaced CFCs as the most potent destroyer of ozone in the upper atmosphere, a study has shown.

Unlike CFCs (chlorofluorocarbons), once extensively used in refrigerators, emissions of the gas are not limited by any international agreement.

From New Scientist:

The sight of eight long black legs scuttling over the floor makes some people scream and run – and women are four times more likely to take fright than men. Now a study suggests that females are genetically predisposed to develop fears for potentially dangerous animals.

David Rakison, a developmental psychologist at Carnegie Mellon University in Pittsburgh, Pennsylvania, found that baby girls only 11 months old rapidly start to associate pictures of spiders with fear. Baby boys remain blithely indifferent to this connection.

From Science Daily:

ScienceDaily (Aug. 27, 2009) — Shell beads newly unearthed from four sites in Morocco confirm early humans were consistently wearing and potentially trading symbolic jewelry as early as 80,000 years ago. These beads add significantly to similar finds dating back as far as 110,000 in Algeria, Morocco, Israel and South Africa, confirming these as the oldest form of personal ornaments. This crucial step towards modern culture is reported this week in the Proceedings of the National Academy of Sciences (PNAS).

A team of researchers recovered 25 marine shell beads dating back to around 70,000 to 85,000 years ago from sites in Morocco, as part of the European Science Foundation EUROCORES programme 'Origin of Man, Language and Languages'. The shells have man-made holes through the centre and some show signs of pigment and prolonged wear, suggesting they were worn as jewelry.

A similar observatory in Washington State is also on the case. LIGO Scientific Collaboration

From Scientific American:

The ripples in spacetime predicted by general relativity remain one of the most sought-after prizes in physics, and new research narrows estimates of their prevalence.

Gravity waves spread through space and time like ripples on a pond, warping the fabric of the universe as they pass. The largest waves emanate from the most cataclysmic events in the universe: stellar explosions, mergers of black holes, and the violent first moments of cosmological history. Or so the venerable theory of general relativity goes—although many predictions of Albert Einstein's theory of gravity have been proved, only indirect evidence for gravity waves has been found.

From The Telegraph:

Competitors who wear red win more than those that are dressed in any other colour, according to a study in Germany.

Researchers found that those who wear red tops, jackets or clothing score 10 per cent more in any competition than if they were in another colour.

Experts believe that red could make individuals and teams feel more confident as well as being perceived by others as more aggressive and dominant.

The findings could explain why Manchester United, Liverpool and Arsenal, have been so successful,. On the other hand, the results could suggest that the success of those teams has given those that wear the red colour more confidence.

Behind the Scenes With the World's Most Ambitious Rocket Makers

SpaceX propulsion chief Tom Mueller examines a spacecraft control thruster.

From Popular Mechanics:

An improbable partnership between an Internet mogul and an engineer could revolutionize the way NASA conducts missions—and, if these iconoclasts are successful, send paying customers into space

In late 2001, Tom Mueller was sacrificing his nights and weekends to build a liquid-fuel rocket engine in his garage.

Mueller, a propulsion engineer at Redondo Beach, Calif.–based aerospace firm TRW, felt like an “unwanted necessity” at his day job. His prolific ideas about engine design were lost at such a large, diverse company. To satisfy his creative impulses, he built his own engines, attached them to airframes and launched them in the Mojave Desert with fellow enthusiasts in the Reaction Research Society, America’s oldest amateur rocketry club. RRS members, many of them employees at aerospace firms, meet regularly in the Los Angeles area to build and launch the biggest and highest flying rockets they can—just as the group has done since it was founded in the early 1940s.

The Equilibrium Concept: A Car That Acts Like A Person

The Equilibrium Concept Car: Automotive designer Bob Romkes's vision for the Equilibrium concept is a car that uses artifical intelligence and other technologies to adapt to a driver's needs, and mimics the responses of a living being. Bob Romkes

From Popular Science:

You love your car, but would you want it to be more human? One designer thinks so.

Ask anyone who's ever talked back to their GPS navigation system: Product developers are pretty good at using technology to humanize inanimate objects. But how would you like it if your car responded to your presence -- lighting up with delight or panting like a pet dog? What if, more helpfully, it recognized your touch on the steering wheel, and queued up your favorite MP3s and set your seating position just the way you liked it? Creepy or no? Either way, that's the future envisioned in the Equilibrium (EQ), a concept car by Dutch designer Bob Romkes that uses artificial intelligence to simulate life and the personality of an individual. Imagine rows of faceless sedans parked at the mall suddenly springing to virtual life, each becoming a sort of Tamagotchi with a purpose.

From Time Magazine:

Farms vs. forests — that's the usual dynamic in tropical countries, where the growth of agriculture often comes at the expense of trees. In nations like Brazil and Indonesia — where deforestation is behind the vast majority of carbon emissions — rain forests are not just cut down for logging but also burned to make room for new farms and pastureland. As more people need more food — and biofuels as well — there's a risk that we could see many of our remaining virgin rain forests wiped out completely.

The Enduring Mystery of Saturn's Rings

From Space.com:

Saturn's rings have fascinated scientists ever since Italian astronomer Galileo Galilei first spotted them through one of his telescopes in the 17th century. But just how the icy rings came into being remains a mystery that has only deepened with each new scientific finding.

Astronomers now know that the planet hosts multiple rings that consist of roughly 35 trillion-trillion tons of ice, dust and rock. The Cassini spacecraft and its Voyager predecessors have also spotted changing ring patterns, partially formed ring arcs and even a moon spewing out icy particles to form a new ring. All of this suggests that the rings have constantly evolved over time.
