From Cosmos:

BRISBANE: Instead of simply focussing on human infections, infectious disease researchers can now track the complex interactions, movement and evolution of the pathogens themselves using supercomputers.

The researchers are using a new program called Supramap, which operates on the computing systems at Ohio State University and the Ohio Supercomputer Center.

The Coming Tide of Global Climate Lawsuits


From Wired Science:

The Prunerov power station is the Czech Republic’s biggest polluter: Its Its 900-foot-high smokestack pushes a plume of white smoke high above the flat, featureless fields of northern Bohemia. Prunerov reliably wins a place on lists of Europe’s dirtiest power plants, emitting 11.1 million tons of carbon dioxide each year. So when CEZ Group, the state-controlled utility, proposed an overhaul to extend the facility’s life for another quarter of a century, protests flared — including one from a place about as far from the sooty industrial region as you can get, a place of tropical temperatures and turquoise seas with not a smokestack in sight. This January, the Federated States of Micronesia, some 8,000 miles away in the Pacific Ocean, lodged a legal challenge to the Prunerov plant on the grounds that its chronic pollution threatens the island nation’s existence.

Study: Brain Exercises Don't Improve Cognition

Brain-training tasks improve performance in the trained tasks alone, rather than improving cognitive performance overall. artpartner-images / Photographer's Choice RF / Getty Images

From Time Magazine:

You've probably heard it before: the brain is a muscle that can be strengthened. It's an assumption that has spawned a multimillion-dollar computer game industry of electronic brain-teasers and memory games. But in the largest study of such brain games to date, a team of British researchers has found that healthy adults who undertake computer-based "brain-training" do not improve their mental fitness in any significant way.

Revealed: The Hapless Apple Engineer Who Lost Top-Secret 4G iPhone Prototype After A Beer-Fuelled Night Out

Already a T-shirt marking Gray Powell's error is on sale

From The Daily Mail:

It has happened to most of us at some point: you arrive home after a night out and can’t remember what on earth you did with your phone.

But - unluckily for this man - a mobile left behind on a bar stool at a German beer garden in Redwood City, California, has set alarm bells ringing with an intrigue worthy of the Cold War.

For a website is claiming that the forgotten phone wasn’t just any old mobile. Gadget blog Gizmodo says it was a secret prototype of the next generation of the iPhone.

And if so, Apple employee Gray Powell has just made his 27th birthday unforgettable.

Climate Science Skepticism: 5 Controversial Claims


From ABC News:

Is Earth Really Warming? Are Humans Responsible? Why Climate Skeptics Doubt

As Earth Day approaches, climate change is climbing back into the public consciousness. But though most climatologists agree that humans are driving global warming, surveys suggest that public concern about climate change is waning.

A Gallup poll in March found that 48 percent of Americans believe the global warming issue is "exaggerated," which is up from 41 percent in 2009 and 31 percent in 1997.

Maxed Out: What's The Human Speed Limit?

Not quite as fast as the speed of light (Image: Seiko Press Service / Getty)

From New Scientist:

Last year, Usain Bolt stunned athletics fans when he hacked 0.11 seconds off his previous world record for the 100-metre sprint. But what's the ultimate human speed limit?

Intrigued by this question, Mark Denny at Stanford University, California, decided to work out how fast a human could possibly sprint 100 metres. He examined previous records for various athletics competitions - and greyhound and horse races for good measure - since the 1920s, and found that performances in many events followed a similar pattern, improving steadily until they reached a plateau. Horses in the Kentucky Derby, for example, appeared to approach their speed limit in 1949. Since then any improvements have become minimal and increasingly rare.

From CNET:

The fastest are getting faster.

Eight of the top 10 countries or regions in terms of Internet speed saw a boost in the final quarter of 2009, according to Akamai's "State of the Internet Report" released Tuesday.

Among those top areas, South Korea, Hong Kong, and Japan grabbed the best Internet performance globally, averaging connection speeds higher than 7.5 megabits per second (Mbps) in the fourth quarter. Although South Korea actually was hit by a 29 percent decline in performance year over year, it still snagged the No. 1 spot at 11.7 Mbps.

Another Iceland Volcano Under Watch

Visible (left) and infrared (right) images of Iceland's Eyjafjallajökull volcano, acquired April 17, 2010, from the Hyperion instrument onboard NASA's Earth Observing-1 (EO-1) spacecraft. Image credit: NASA/JPL/EO-1 Mission/GSFC/Ashley Davies

From Live Science:

News reports earlier today that another volcano on Iceland had erupted just as Eyjafjallajokull was beginning to calm down turned out to be false. But scientists are warily keeping their eye on one of Eyjafjallajokull's neighbors, which has been known to erupt following its sister.

An MSNBC Twitter feed and one other news service ran reports that a volcano called Hekla had erupted on Iceland today. Those rumors turned out to be false, but even if Hekla had blown its top today, it would have been "purely coincidental," said Jay Miller, a volcano researcher at Texas A&M University.

Maxed Out: How Long Can We Concentrate For?

Surgeons have to concentrate for hours on end (Image: OJO Images / Rex Features)

From New Scientist:

It's a challenge that most of us have faced when up against an essay deadline, a late-night crisis in the office or perhaps a long car drive. Just how long can we push ourselves mentally before our brain needs a break?

For people in jobs where concentration is critical, like truck drivers, power-plant operators or airline pilots, a 12-hour shift is the limit for most. But pity doctors: complex surgery can go on for hours longer than that, although the lengthiest operations tend to be shared by more than one team.

Five Biggest Volcano Eruptions In Recent History

This picture is of a June 12, 1991, eruption of Mt. Pinatubo in the Philippines – one of the smaller eruptions that preceded the main eruption on June 15. That eruption was the biggest since 1912 – a 6 on the Volcanic Explosivity Index. The eruption of Iceland's Eyjafjallajökull volcano rates a 2 or 3. Newscom

From Christian Science Monitor:

The eruption at Eyafjallajökull volcano in Iceland has been hugely disruptive to world travel. But as a volcanic event, it's barely worth mentioning.


By the measure of the Volcanic Explosivity Index (VEI) – a sort-of Richter scale for eruptions – the current outburst is probably a 2 or a 3, experts say. In other words, eruptions like Eyjafjallajökull happen virtually every year somewhere in the world.

From CNET:

Gizmodo said Monday evening it is making arrangements to return an errant device that is believed to be a prototype of the next iPhone, following a request from Apple's legal department, which Gizmodo calls verification of the device's authenticity.

The tech blog site had revealed early Monday that it was in possession of a device it concluded to be a prototype of the unreleased and as-yet-unannounced iPhone 4G. The next-generation device was reportedly found last month on the floor of a San Francisco Bay Area bar after it was apparently left by a customer identified as an Apple employee.

A Saturn Spectacular, With Gravity’s Help

SEVEN MORE YEARS Brent Buffington, from left, David Seal and John C. Smith arranged models of Jupiter and Saturn in a viewing room at the Jet Propulsion Laboratory, in Pasadena, Calif. Robert Benson for The New York Times

From The New York Times:

When it comes to voyages of discovery, NASA’s venerable Cassini mission is about as good as it gets.

In six years of cruising around the planet Saturn and its neighborhood, the Cassini spacecraft has discovered two new Saturn rings, a bunch of new moons and a whole new class of moonlets. It encountered liquid lakes on the moon Titan, water ice and a particle plume on the moon Enceladus, ridges and ripples on the rings, and cyclones at Saturn’s poles. Cassini also released a European space probe that landed on Titan. And Cassini has sent back enough data to produce more than 1,400 scientific papers — at last count.

Bureaucracy Linked To A Nation's Growth

Two of the conquest inscriptions on Building J (ca. 100 BC). Each inscription shows an upside down head with closed eyes signifying conquest on the bottom, a "hill" glyph signifying generalized place in the middle, and a third element on top that varies among inscriptions signifying specific place name.

From Science Daily:

ScienceDaily (Apr. 20, 2010) — "Bureaucracy is the death of all sound work," said Albert Einstein, sharing a popular view about bureaucracy grinding progress to a halt.

But it now appears that the organizing functions of bureaucracy were essential to the progressive growth of the world's first states, and may have helped them conquer surrounding areas much earlier than originally thought. New research conducted in the Valley of Oaxaca near Monte Albán, a large pre-Columbian archaeological site in southern Mexico, also implies that the first bureaucratic systems may have a lasting influence on today's modern states.

From Live Science:

It may look like the special effects from a disaster movie, but the bolts of lightning photographed in the plume of the ash-spewing Icelandic volcano are real. Thing is, the process that creates volcano lightning remains a bit of a mystery.

Several photographers have taken pictures of the stunning light show shooting from the angry mouth of Eyjafjallajokull, which has been pumping a cloud of ash into the atmosphere for several days. In addition to the spectacular electric storm in its plume, the volcano has created colorful sunsets around the world with its ash, which has also hampered air travel over Europe.

A Trick Of The Light -- Mankind’s Ability To Look For Planets Like Earth Just Got Five Times Bette

First rock from the sun

From The Economist:

THREE centuries have passed since the polymath Sir Christopher Wren predicted that “a time will come when men will stretch out their eyes—they should see planets like our Earth.” By most astronomers’ accounts, that time is just about nigh. Indeed, detecting big planets orbiting other stars is no longer tricky—nearly 450 such exoplanets have been catalogued. Smaller, rocky planets orbiting at a comfortable distance from their stars—as the Earth does—remain more elusive.

Head-Ramming Dino Had 'Gears' in Skull

A reconstruction of Texacephale langstoni shows how the dinosaur may have used its head. Nicholas Longrich

From The Telegraph:

The new Texas dino featured a skull with a domed top and side bones that may have allowed its skull bones to mesh on impact.

A new species dinosaur found in Texas featured flanges on the side of its skull that may have allowed its skull bones to mesh like gears -- a useful feature when it likely rammed heads with other dinosaurs, say researchers.

"It's possible that this would prevent the skull bones from dislocating under stresses," speculated Nicholas Longrich, a postdoctoral associate in Yale University's Department of Geology and Geophysics who was project leader for a study about the find published in the latest issue of the journal Cretaceous Research.

The Image Microsoft Doesn't Want You To See

Worn out: Some of the workers making computer accessories for Microsoft at a Chinese factory

From The Daily Mail:

Showing Chinese sweatshop workers slumped over their desks with exhaustion, it is an image that Microsoft won't want the world to see.

Employed for gruelling 15-hour shifts, in appalling conditions and 86f heat, many fall asleep on their stations during their meagre ten-minute breaks.

For as little as 34p an hour, the men and women work six or seven days a week, making computer mice and web cams for the American multinational computer company.

Is God A Mathematician?

From afar, Richard Feynman seemed as dangerous as plutonium (Image: CERN/SPL)

From New Scientist:

THE physicist Richard Feynman said, "It doesn't seem to me that this fantastically marvellous universe, this tremendous range of time and space and different kinds of animals, and all the different planets, and all these atoms with all their motions, and so on, all this complicated thing can merely be a stage so that God can watch human beings struggle for good and evil - which is the view that religion has. The stage is too big for the drama."
