Lake Superior Is Freezing Over

From Watts Up With That?

Lake Superior last froze over in 2003. It has now, again, frozen over. The frequency of freeze overs has historically been around once every 20 years. Now, in the last decade, we have seen two freeze overs.

The picture below is a beautiful satellite photo of Lake Superior from yesterday. With the well below freezing temperatures seen over the region Thursday night (-20 F), any isolated open water could have frozen.

From The L.A. Times:

The $590-million mission, jointly managed by JPL and NASA, will examine a star-rich stretch of sky for a planet where water could exist in liquid form.

NASA's Kepler spacecraft blasted off from Kennedy Space Center in Florida on Friday on a three-year mission to find Earth's twin, a Goldilocks planet where it's neither too hot nor too cold, but just right for life to take hold.

The Delta II rocket, carrying the widest-field telescope ever put in space, lifted off the launch pad at Cape Canaveral at 10:49 p.m. Eastern time.

The launch vehicle headed downrange, gathering speed as its three stages ignited, one after the other, passing over the Caribbean island of Antigua and tracking stations in Australia before climbing into orbit.

From Science Daily:

ScienceDaily (Mar. 6, 2009) — Naked mole rats resemble pink, wrinkly, saber-toothed sausages and would never win a beauty contest, even among other rodents. But these natives of East Africa are the champs for longevity among rodents, living nine times longer than similar-sized mice. Not only do they have an extraordinarily long lifespan, but they maintain good health for most of it and show remarkable resistance to cancer.

Researchers at The University of Texas Health Science Center at San Antonio are studying mechanisms that enable the prolonged good health and slowed aging of naked mole rats in their large colony at the university’s Barshop Institute for Longevity and Aging Studies. In the March 3 print edition of Proceedings of the National Academy of Sciences, the scientists report on another unusual feature of the animals — tissues of the naked mole rat are remarkably efficient at discarding damaged proteins and thereby maintaining stable, high-quality proteins.

Wine and Beer May be Good for Your Bones

From Live Science:

A glass of wine or a bottle or two of beer a day may strengthen the bones of older men and women, but drinking more than that could actually weaken bones, according to new research from the Human Nutrition Research Center on Aging at Tufts University in Boston.

The research, on men and post-menopausal women over 60 years of age, found that regular moderate alcohol intake was associated with greater bone mineral density (BMD).

From The Independent:

British scientists search for life forms hidden more than 400,000 years ago beneath Antarctic ice.

British scientists are about to mount one of the boldest-ever missions, to search for life forms that have survived for possibly millions of years in a frozen "lost world" beneath an ancient ice sheet.

This week, a team of Antarctic scientists has been given the go-ahead to drill through a two-mile-thick sheet of ice that has sealed a sub-glacial lake from the rest of the biosphere for at least as long as Homo sapiens has walked the Earth.

Q&A: Mitchell Baker On The Future Of Firefox

Browsing The Future -- Newsweek

Mozilla's Firefox gave Microsoft a run for its money. What's next?

At least 18 percent of you already know what Firefox is, because you're using it to read this interview. (Or so says the statistics engine behind Newsweek.com, which tracks things like that.) For the unfamiliar, Firefox is a free Web browser that is built by coders around the world whose open-source work is organized by the Mozilla Corp. and its nonprofit parent, the Mozilla Foundation. Introduced in 2004 as an alternative to Microsoft's ubiquitous, but buggy, Internet Explorer, Firefox has been a force for innovation in the browser category, with improvements such as tabbed browsing and plug-ins that work on any operating system. Commissions from search engines appear to keep Mozilla awash in revenue for now ($75 million in 2007; the foundation has not released 2008 data), although the vast majority of that comes from a company, Google, that now has its own competing browser, Chrome. Mozilla's plans for 2009 include a new version of Firefox, which will focus on user-interface polish; an overhaul of Thunderbird, its e-mail client; and taking Firefox mobile. Mitchell Baker, the Mozilla Foundation's chairwoman, spoke to NEWSWEEK's Nick Summers and Barrett Sheridan about the challenges of making a browser for mobile phones, adapting to a socially networked universe and what she really thinks of Chrome and Internet Explorer.

Bionic Eye Lets The Blind See

Ron who has a bionic eye as featured on BBC's Inside Out.

From The Telegraph:

A bionic eye has allowed a blind patient to see well enough to sort his socks and work the washing machine after one of the first operations of its kind in the UK.

Ron, 73, is one of just three patients in the UK to be fitted with a bionic eye and after 30 years of being completely blind he can now see well enough to do the laundry.

The operation was carried out at Moorfields Eye Hospital in London seven months ago and Ron's sight has steadily improved since then.

He lost his sight in his 40s after suffering from a disease called retinitis pigmentosa but now thanks to the operations he is regaining some of his independence.

Telescope 'Cousins' Meet At Last

Scheduled to launch in April 2009, the Herschel and Planck space telescopes bring capabilities never before available to study the origins of stars, galaxies and the universe. The expected data might revolutionize both astrophysics and philosophy. Image from Environmental Graffitti.

From The BBC:

Europe's Herschel and Planck space telescopes have finally come together.

The satellites now share a common cleanroom at the Kourou spaceport in French Guiana, from where they will be despatched into orbit on 16 April.

The observatories have been produced as part of a joint programme that has taken more than 10 years to develop and which is worth some 1.9bn euros.

Their arrival in the S1 preparation hall at Kourou marks the first time the pair have come face to face.

From Nevada Appeal:

WASHINGTON — For two decades, a ridge of volcanic rock 90 miles northwest of Las Vegas known as Yucca Mountain has been the sole focus of government plans to store highly radioactive nuclear waste.

Not anymore.

Despite the $13.5 billion that has been spent on the project, the Obama administration says it’s going in a different direction.

It slashed funding for Yucca Mountain in its recently announced budget.

And on Thursday, Energy Secretary Steven Chu told a Senate hearing that the Yucca Mountain site no longer was viewed as an option for storing reactor waste, brushing aside criticism from several Republican lawmakers.

The Kepler Telescope: Taking A Census Of The Galaxy

At the Astrotech payload processing facility in Titusville, Florida, workers from Ball Aerospace check the star trackers on NASA's Kepler spacecraft before testing. NASA

From Time Magazine:

Think you could stare at a single spot without blinking for three and a half years? Then be glad you're not NASA's Kepler telescope, which is set to blast into space from Cape Canaveral this Friday night. Kepler's job may sound boring to you, but what the spacecraft accomplishes could be extraordinary: the discovery of the first Earth-like planets orbiting sun-like stars. Those kinds of places might well be brewing Earth-like forms of life.

From Science Daily:

ScienceDaily (Mar. 5, 2009) — Schizophrenia could be caused by faulty signalling in the brain, according to new research published in the journal Molecular Psychiatry. In the biggest study of its kind, scientists looking in detail at brain samples donated by people with the condition have identified 49 genes that work differently in the brains of schizophrenia patients compared to controls.

Many of these genes are involved in controlling cell-to-cell signalling in the brain. The study, which was carried out by researchers at Imperial College London and GlaxoSmithKline, supports the theory that abnormalities in the way in which cells 'talk' to each other are involved in the disease.

Exercise: The Best Medicine

New studies find exercise makes for better eye health, less chronic pain, stronger bones and can even help prevent some cancer. Image credit: Dreamstime

From Live Science:

It just seems too good to be true. Study after research study consistently promoting the endless benefits of exercise. Couch potatoes everywhere are waiting for the other shoe to drop, telling us that all of those scientists were wrong and we should remain as sedentary as possible.

Yet four additional studies released recently each give the same prescription for improving some aspect of your health: exercise.

They add to recent evidence that regular workouts can improve old brains, raise kids' academic performance and give a brain boost to everyone in between.

from Earth, March 3, 2009. (AP / CBS)

From CBS News:

(AP) An asteroid about the size of one that blasted Siberia a century ago just buzzed the Earth.

The asteroid named 2009 DD45 was about 48,800 miles from Earth when it zipped past early Monday, NASA's Jet Propulsion Laboratory reported.

That is just twice as high as the orbits of some telecommunications satellites and about a fifth of the distance to the Moon.

"This was pretty darn close," astronomer Timothy Spahr of the Harvard-Smithsonian Center for Astrophysics said Wednesday.

But not as close as the tiny meteoroid 2004 FU162, which came within 4,000 miles in 2004.

From Technology Review:

The first bendable, touch-screen display will be used by the military.

Researchers have developed the first computer display that is both flexible and touch sensitive. They say that the breakthrough could lead to more practical and easier-to-use portable devices.

Over the past few years, there has been a drive to develop displays that more closely mimic the properties of paper.

E Ink, based in Cambridge, MA, already supplies displays that are easy to read in direct sunlight and require little power for both the Amazon Kindle and the Sony Reader, compared to LCDs and plasma screens. E Ink's technology uses a layer of microcapsules filled with submicrometer black and white particles to create a low-power, reflective screen.
