From CNET:

I was at Apple's iPad launch on Wednesday, and maybe it was just Steve Jobs' reality distortion field, but I don't quite understand why the haters are piling on. A lot of PC-centric commentators are dismissing the iPad as an overpriced gadget, wondering why it's lacking features that are standard on even the cheapest notebook computers, like Flash support, multitasking, USB inputs to connect peripherals, and video outputs (HDMI would be nice). These are legitimate complaints--for a notebook replacement. But the iPad isn't a notebook replacement, and I don't think users will carry it with them on business trips. (Apple's iWork demo confused matters, admittedly.)

The Tell Tail Clue To A Happy Dog... They Wag It To The Left

Photo: Welcome sign: A wag to the left is friendlier than one to the right

From The Daily Mail:

Everyone knows that if a dog's ears are up and its tail is wagging vigorously, it is definitely pleased to see you.

Now, scientists using a robot have found that the way dogs use their tails is more subtle than we thought and that dogs that wag them to the left may be more friendly.

The animal psychologists discovered that when real dogs approached a life-sized black Labrador with a mechanical tail, they were less wary of it when it was wagging its tail on the left side of its body.

Magnesium May Boost Brainpower

From Live Science:

Mice given extra doses of a new magnesium compound had better working memory, long-term memory and greater learning ability.

Before you go popping heavy doses of magnesium, however, know that much more testing is needed. Though rodent brains work similarly to ours, animal studies do not always predict what will happen in humans.

"If MgT is shown to be safe and effective in humans, these results may have a significant impact on public health," said Guosong Liu, director of the Center for Learning and Memory at Tsinghua University in Beijing, China.

NASA Budget For 2011 Eliminates Funds For Manned Lunar Missions

From The Washington Post:

NASA's grand plan to return to the moon, built on President George W. Bush's vision of an ambitious new chapter in space exploration, is about to vanish with hardly a whimper. With the release Monday of President Obama's budget request, NASA will finally get the new administration's marching orders, and there won't be anything in there about flying to the moon.

The budget numbers will show that the administration effectively plans to kill the Constellation program that called for a return to the moon by 2020. The budget, expected to increase slightly over the current $18.7 billion, is also a death knell for the Ares 1 rocket, NASA's planned successor to the space shuttle. The agency has spent billions developing the rocket, which is still years from its first scheduled crew flight.

I, Virus: Why You're Only Half Human

Part of our DNA (Image: Mehau Kulyk/SPL/Getty)

From New Scientist:

WHEN, in 2001, the human genome was sequenced for the first time, we were confronted by several surprises. One was the sheer lack of genes: where we had anticipated perhaps 100,000 there were actually as few as 20,000. A bigger surprise came from analysis of the genetic sequences, which revealed that these genes made up a mere 1.5 per cent of the genome. This is dwarfed by DNA deriving from viruses, which amounts to roughly 9 per cent.

On top of that, huge chunks of the genome are made up of mysterious virus-like entities called retrotransposons, pieces of selfish DNA that appear to serve no function other than to make copies of themselves. These account for no less than 34 per cent of our genome.

Scientists Set For Nuclear Fusion Fuel Switch-On

From The Independent:

A pivotal step in the march towards fusion power, the "Holy Grail" of sustainable clean energy, could be taken this year.

Scientists in the US are preparing for the dramatic moment when the world's most powerful laser unleashes the nuclear force that lights up the Sun and achieves "ignition".

At that moment, 192 laser beams housed in a building the size of three football pitches will focus on a target the size of a peppercorn to trigger a self-sustaining fusion reaction.

From Technology Review:

Engineers are developing a more flexible outfit--just the thing for a mission to the moon.

If NASA returns to the moon in 2020 as planned, astronauts will step out in a brand-new space suit. It will give them new mobility and flexibility on the lunar surface while still protecting them from its harsh environment. The suit will also be able to sustain life for up to 150 hours and will even be equipped with a computer that links directly back to Earth.

Archaeology In Jerusalem: Digging Up Trouble

From Time Magazine:

The Jerusalem syndrome is a psychological disorder in which a visit to the holy city triggers delusional and obsessive religious fantasies. In its extreme variety, people wander the lanes of the Old City believing they are biblical characters; John the Baptist, say, or a brawny Samson, sprung back to life.

Archaeologists in the Holy Land like to joke that their profession is vulnerable to a milder form of the syndrome. When scientists find a cracked, oversize skull in the Valley of Elah, it can be hard to resist the thought that it might have belonged to Goliath, or to imagine, while excavating the cellars of a Byzantine church, that the discovery of a few wooden splinters might be part of the cross on which Christ died. This milder malady is nothing new. In the mid-19th century, British explorers who came to Jerusalem with a shovel in one hand and a Bible in the other used the holy book as a sort of treasure map in the search for proof of Christianity's origins.

From Science Daily:

Science Daily (Jan. 30, 2010) — A new experiment that reproduces the magnetic fields of the Earth and other planets has yielded its first significant results. The findings confirm that its unique approach has some potential to be developed as a new way of creating a power-producing plant based on nuclear fusion -- the process that generates the sun's prodigious output of energy.

Fusion has been a cherished goal of physicists and energy researchers for more than 50 years. That's because it offers the possibility of nearly endless supplies of energy with no carbon emissions and far less radioactive waste than that produced by today's nuclear plants, which are based on fission, the splitting of atoms (the opposite of fusion, which involves fusing two atoms together). But developing a fusion reactor that produces a net output of energy has proved to be more challenging than initially thought.

How Much Sleep Do I Need?

From Live Science/Tech Media:

Scientists can't say exactly how much sleep each person needs, but there are some guidelines. And you should know that serious lack of sleep — less than six or seven hours a night — has been associated with increased risks of high blood pressure, hypertension, obesity, diabetes and cancer.

But much about sleep's role in health, and the how much sleep each person needs, remains a mystery. Some studies have suggested that older people need less sleep. Research reported in the journal Current Biology in 2008 found that when asked to stay in bed for 16 hours in the dark each day for several days, younger people participants slept 9 hours on average while older people got 7.5 hours of shut-eye.

From CBS News:

Amazon provided its most detailed figures on sales of its Kindle, putting the units in the marketplace in the millions. The big questions: How long can Amazon defend its turf vs. Apple's iPad? And will consumers consider the iPad and Kindle to be two completely different devices with different use cases?

The e-commerce giant on Thursday reported another strong quarter, but the highlight of the financials and the call may have been at least some detail on Kindle sales. Due to an accounting change where Amazon can recognize more Kindle revenue up-front, the company had to offer a little more detail than usual about sales. Granted, Amazon didn't offer much, but CEO Jeff Bezos said in a statement:

iPad's Big Target: E-Readers

From PC World:

The new Apple iPad's color multitouch display will clobber -- but not kill -- the blossoming e-reader market, which includes Amazon.com's Kindle, the Sony Reader and other devices that use gray-scale displays and slower interfaces, some analysts said.

"Apple 's full-color, full motion [iPad] device makes not only netbooks, but any product with an E Ink display look tired and dated," wrote Yankee Group analyst Carl Howe in a blog after spending a few minutes using the tablet device.
