Dream A Little Dream Of Recall

From Science News:

Nap-time reveries may show that sleeping brain is making memories.

People who have nap-time dreams about a task that they’ve just practiced get a big memory boost on the task upon awakening, Harvard researchers report.

Those who dream about anything else have no such enhanced recall, the team reports in a paper published online April 22 in Current Biology. Neither do those who stay awake, even if they think about the task.

Toilet Paper Problem: Good Raw Material Being Wiped Out

From Live Science:

A shortage of high-quality paper for recycling could mean scratchy toilet tissue. To keep consumers happy and avoid any chafed rear ends, companies are now on a quest to find new paper supplies, according to an article in the current issue of Chemical & Engineering News (C&EN).

The problem: Consumers once could fill up large bins with their recycled newspapers, magazines and print paper. But as electronic communication surges, these sources of recycled paper are becoming scarce.

From Epicenter:

Apple appears to have been right in betting that people would embrace a big version of the iPod Touch; the increased sense of intimacy with no keyboard or mouse chaperons is palpable. But even larger touchscreens, like the one the Finnish company MultiTouch let us play around with last week, can track each fingertip of a large group of people — a key distinction that enables a more social set of behaviors, because multiple people can use them at the same time.

Accidents Don’t Slow Gulf Of Mexico Drilling

From New York Times:

As the Coast Guard was trying to assess the potential environmental effect of the oil rig explosion near Louisiana, industry officials said Thursday that they did not expect drilling in the Gulf of Mexico’s deep waters to be curtailed.

“It’s a tragedy, but at the end of the day we are not going to stop doing things that need to be done,” said Larry Goldstein, a director of the Energy Policy Research Foundation. Eleven workers remained missing Thursday, and several others were injured seriously.

From New Scientist:

Zi Ye and Hammad Khalid of the Human Media Lab at Queen's University in Kingston, Ontario, Canada, have devised a way of using a shoulder-mounted projector system to display - and play - a game on a bendy A4-sized sliver of plastic. Sensors in the screen allow gameplay to be controlled by bending, shaking or tapping it.

A prototype of the system, called Cobra, was shown last week at the Computer-Human Interaction meeting in Atlanta, Georgia. It runs games on a computer housed in a shoulder pouch, while the pouch's straps hold a small projector that shines images onto the flexible screen, held by the gamer.

From Popular Science:

What if you could go to sleep with a vision problem and wake up with a crystal-clear view of the world? A Spanish optometrist not only says this is possible, but he actually wants you to sleep in your contacts. His patented contact lenses, designed to achieve the same effect of corneal reshaping surgery, can correct vision defects like myopia (nearsightedness) and stigmatism – and now hyperopia (farsightedness) – without taking sharp instruments or lasers to your eyes.

Red Wine Bolsters Brain Against Strokes

From The Telegraph:

Red wine protects the brain from damage after a stroke, new research suggests.

Researchers discovered that a compound found in red grape skins and seeds lessens the effect of a blood clot on the brain and aids recovery.

It could be so effective that the substance, known as resveratrol, reduces the long-term brain damage by as much as 40 per cent.

Millions Of Computers Shut Down As Faulty Anti-Virus Program Causes Havoc Around The Globe

Big freeze: A faulty software update from McAfee led to thousands of PCs repeatedly rebooting in offices, hospitals and schools around the world

From The Daily Mail:

Computers in companies, hospitals and schools around the world slowed down or froze after an antivirus program identified a normal Windows file as a threat.

While the problem has now been identified, IT technicians are today having to deal with extra workloads to ensure their systems are protected.

Antivirus vendor McAfee Inc confirmed that yesterday a software update had caused its antivirus program for corporate customers to target a harmless file, leading PCs to repeadedly reboot themselves.

Diving Deep Into A Solar Prominence (SDO First Light)

April 21, 2010 -- What you're seeing here is the highest resolution photograph of the sun available to date, part of a brand new series of NASA Solar Dynamics Observatory (SDO) observations. The SDO mission promises "10 times better clarity than a high-definition television," NASA says, and this first SDO image doesn't disappoint.

From Discovery News:

Taken from a series of movies of bubbling plasma erupting to the solar surface, this is a close-up shot of what's called an expanding solar prominence, seen in extreme ultraviolet light. We are basically looking deep into the throat of the fine structure of an eruption on our nearest star.

The light we are seeing in this observation is generated by plasma heated to around 50,000 Kelvin (twice as hot as a bolt of lightning). A solar prominence is a looped structure of hot plasma, wrapped in magnetic fields from the sun's "surface" (or the photosphere), projecting high into the solar atmosphere (the sun's corona). But this is only one of the many eyes of SDO; it is already revolutionizing our understanding of the sun.

Maxed Out: How Cold Can You Get And Live?

Chill out, this won't hurt a bit (Image: Ty Milford / Getty)

From New Scientist:

Humans hate being cold, and for good reason: our long-limbed bodies are exquisitely adapted to lose heat, not to retain it. This makes perfect sense in the intense heat of the African savannah, where humans evolved. Without our technological adaptations to cold - clothing, heating, shelter - that's where we'd all still be living, says Mike Tipton of the University of Portsmouth, UK, who studies human thermoregulation.

Stargazers are preparing for a sky show as the annual Lyrids meteor shower gets underway on Wednesday.

The shower is named after the constellation Lyra, from which the meteors appear to originate.

The meteor shower peaks early on Thursday 22 April (GMT), when 10-20 meteors per hour are expected to be visible under favourable conditions.

Scientists say the best time to observe the meteor shower is during the dark hours before dawn.

Magnesium Power: White-Hot Energy

From The Economist:

New power sources could be made using magnesium.

STORING energy is one of the biggest obstacles to the widespread adoption of alternative sources of power. Batteries can be bulky and slow to charge. Hydrogen, which can be made electrolytically from water and used to power fuel cells, is difficult to handle. But there may be an alternative: magnesium. As school chemistry lessons show, metallic magnesium is highly reactive and stores a lot of energy. Even a small amount of magnesium ribbon burns in a flame with a satisfying white heat. Researchers are now devising ways to extract energy from magnesium in a more controlled fashion.
