The FuA- Men

Robot Chefs Run a Restaurant

The FuA-Men - Fully Automated raMen restaruant in Nagoya, Japan features a chef and assistant - both fully autonomous robots. The robots perform all of the cooking tasks needed to make eighty bowls per day, serving the customers who come to their small shop.
When asked, customers seem to feel that there is little difference between noodle dishes prepared by real, human chefs, and meals prepared by autonomous robots. For those who appreciate precision in food preparation, you can't beat robot chefs.
"The benefits of using robots as ramen chefs include the accuracy of timing in boiling noodles, precise movements in adding toppings and consistency in the taste and temperature of the soup," said Kenji Nagaya, president of local robot manufacturer Aisei.
The two chefs also work very well together; their movements are perfectly choreographed (see video).

From Yahoo News/AFP:

LONDON, (AFP) – Mosquitoes brought into the Galapagos on tourist planes and boats threaten to wreak "ecological disaster" in the islands, central to Darwin's theory of evolution, a study said Wednesday.

The insects can spread potentially lethal diseases in the archipelago off Ecuador's Pacific coast, used by Charles Darwin as the basis of his seminal work "On the Origin of Species by Means of Natural Selection".

"Few tourists realise the irony that their trip to Galapagos may actually increase the risk of an ecological disaster," said Simon Goodman of Leeds University, one of the study's co-authors.

From New Scientist:

AS THE swine flu pandemic continues to sweep the world, what do public health officials, epidemiologists and flu researchers think will happen in the coming months? When New Scientist asked 60 of them, it turned out that half are concerned enough about the possibility of a virulent swine flu outbreak to take precautions such as acquiring a supply of Tamiflu for their families. Though most do not think it likely that a nastier strain will emerge, many are worried that if it did, their local hospitals and other parts of the health infrastructure could not cope.

NASA Falling Short of Asteroid Detection Goals

The team says it is almost certain that a large Baptistina fragment created the 180km Chicxulub crater off the coast of the Yucatan 65 million years ago. The impact that produced this crater has been strongly linked to the mass extinction event that eliminated the dinosaurs. Image from The BBC.

From Wired Science:

Without more funding, NASA will not meet its goal of tracking 90 percent of all deadly asteroids by 2020, according to a report released today by the National Academy of Sciences.

The agency is on track to soon be able to spot 90 percent of the potentially dangerous objects that are at least a kilometer (.6 miles) wide, a goal previously mandated by Congress.

Asteroids of this size are estimated to strike Earth once every 500,000 years on average and could be capable of causing a global catastrophe if they hit Earth. In 2008, NASA’s Near Earth Object Program spotted a total of 11,323 objects of all sizes.

Mars, Methane And Mysteries

From Scientific American:

Mars may not be as dormant as scientists once thought. The 2004 discovery of methane means that either there is life on Mars, or that volcanic activity continues to generate heat below the martian surface. ESA plans to find out which it is. Either outcome is big news for a planet once thought to be biologically and geologically inactive.

The methane mystery started soon after December 2003, when ESA's Mars Express arrived in orbit around the red planet. As the Planetary Fourier Spectrometer (PFS) began taking data, Vittorio Formisano, Istituto di Fisica dello Spazio Interplanetario CNR, Rome, and the rest of the instrument team saw a puzzling signal. As well as the atmospheric gases they were anticipating, such as carbon monoxide and water vapour, they also saw methane. "Methane was a surprise, we were not expecting that," says Agustin Chicarro, ESA Mars Lead Scientist. The reason is that on Earth much of the methane in our atmosphere is released by evolved life forms, such as cattle digesting food. While there are ways to produce methane without life, such as by volcanic activity, it is the possible biological route that has focused attention on the discovery.

What's Luck Got To Do With It? The Math Of Gambling

From New Scientist:

FIVE years ago, Londoner Ashley Revell sold his house, all his possessions and cashed in his life savings. It raised £76,840. He flew to Las Vegas, headed to the roulette table and put it all on red.

The wheel was spun. The crowd held its breath as the ball slowed, bounced four or five times, and finally settled on number seven. Red seven.

Revell's bet was a straight gamble: double or nothing. But when Edward Thorp, a mathematics student at the Massachussetts Institute of Technology, went to the same casino some 40 years previously, he knew pretty well where the ball was going to land. He walked away with a profit, took it to the racecourse, the basketball court and the stock market, and became a multimillionaire. He wasn't on a lucky streak, he was using his knowledge of mathematics to understand, and beat, the odds.

First Black Holes Born Starving

FROM SCIENCE DAILY

The first black holes in the universe

The simulations were carried out by astrophysicists Marcelo Alvarez and Tom Abel of the Kavli Institute for Particle Astrophysics and Cosmology, jointly located at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University, and John Wise, formerly of KIPAC and now of NASA Goddard Space Flight Center.
Several popular theories posit that the first black holes gorged themselves on gas clouds and dust in the early universe, growing into the supersized black holes that lurk in the centers of galaxies today. However, the new results, published in The Astrophysical Journal Letters, point to a much more complex role for the first black holes.
"I'm thrilled that we now can do calculations that start to capture the most relevant physics, and we can show which ideas work and which don't," said Abel. "In the next decade, using calculations like this one, we will settle some of the most important issues related to the role of black holes in the universe."

The Flu Hunters: Racing To Outsmart A Pandemic

Research student Nick Cattle, working in the flu lab at the World Influenza Centre
Philip Hollis for TIME

From Time Magazine:

On April 25, Rod Daniels, the deputy director of the World Influenza Centre in London, was at a meeting in Germany when he received a call from a co-worker: an influenza outbreak had been reported in Mexico and the first samples of the virus were on their way to London for examination. A virologist who has studied flu for more than 30 years, Daniels knew exactly what he was looking for. Influenza A viruses — the type that can cause pandemics — use a protein called hemagglutinin to bind to the cells of their animal hosts. When a virus jumps from animals to humans, its contagiousness is largely determined by what is called the "binding specificity" of this protein. An alpha-2,3 binding specificity means the virus is well suited to the cells in an animal respiratory tract but probably not human cells. An alpha-2,6 binding specificity, on the other hand, means the virus can easily bind to human cells.

Perseid Meteors To Shower Down Late Tuesday, Early Wednesday

From Salt Lake Tribune:

The most-watched meteor shower of the year is coming back late Tuesday and into Wednesday morning, and this year, stargazers may be treated to even more fiery streaks of light zooming across the night sky.

Under the right conditions, observers away from city light pollution are sometimes able to see an average of one and sometimes two Perseid meteors per minute, said Patrick Wiggins, NASA solar system ambassador to Utah.

"But this year," he said, "NASA is predicting the possibility of an enhanced shower Wednesday morning between 2 and 3 a.m."

The more frequent meteor sightings could happen if the Earth passes through what astronomers suspect to be a particularly rich pocket of meteor-producing particles cast off by the shower's parent comet nearly 400 years ago in 1610.

Earth Rotational Periods Cause Ice Ages And Warmings

From Future Pundit:

Changes in how large planets such as Jupiter and Saturn pull at the Earth's rotation cause the Earth to go into periodic cooling and warming periods.

CORVALLIS, Ore. – Researchers have largely put to rest a long debate on the underlying mechanism that has caused periodic ice ages on Earth for the past 2.5 million years – they are ultimately linked to slight shifts in solar radiation caused by predictable changes in Earth's rotation and axis.

In a publication to be released Friday in the journal Science, researchers from Oregon State University and other institutions conclude that the known wobbles in Earth's rotation caused global ice levels to reach their peak about 26,000 years ago, stabilize for 7,000 years and then begin melting 19,000 years ago, eventually bringing to an end the last ice age.

The new finding, based on survey data, reveals that such manly beliefs could help to explain the lower life expectancy of men compared with women.

In the United States in 2005, life expectancy for women averaged about 80 years, while for men it was about 75 years, according to the Centers for Disease Control and Prevention.

While NOAA is lowering forecasts, the Accumulated Cyclone Energy (ACE) from FSU COAPS is also quite low. Ryan Maue’s Tropical web page at Florida State University has this graph that shows accumulated cyclone energy (ACE)

From Watts Up With That?

According to its August Atlantic hurricane season outlook, NOAA now expects a near- to below-normal Atlantic hurricane season, as the calming effects of El Niño continue to develop. But scientists say the season’s quiet start does not guarantee quiet times ahead. The season, which began June 1, is entering its historical peak period of August through October, when most storms form.

1 Million MPH Stars Move Through Galaxy

From FOX News/Space:

Stars in a distant galaxy move at stunning speeds — greater than 1 million mph, astronomers have revealed.

These hyperactive stars move at about twice the speed of our sun through the Milky Way, because their host galaxy is very massive, yet strangely compact. The scene, which has theorists baffled, is 11 billion light-years away. It is the first time motions of individual stars have been measured in a galaxy so distant.

While the stars' swiftness is notable, stars in other galaxies have been observed to travel at similarly high speeds. In those situations, it was usually because they were interlopers from outside, or circling close to a black hole.

From Science Daily:

ScienceDaily (Aug. 9, 2009) — The rain band near the equator that determines the supply of freshwater to nearly a billion people throughout the tropics and subtropics has been creeping north for more than 300 years, probably because of a warmer world, according to research published in the July issue of Nature Geoscience.

If the band continues to migrate at just less than a mile (1.4 kilometers) a year, which is the average for all the years it has been moving north, then some Pacific islands near the equator – even those that currently enjoy abundant rainfall – may be drier within decades and starved of freshwater by midcentury or sooner. The prospect of additional warming because of greenhouse gases means that situation could happen even sooner.
