Panasonic's Robotic Bed Transforms into a Mobile Chair, Makes Standing Up Obsolete

Robo-Bed: It will do everything but fix your bed hair. Panasonic

From Popular Science:

Mobility-impaired patients and layabouts alike can rejoice at the debut of Panasonic's robotic bed that transforms into a wheelchair. Human nurses and hospitals may also breathe a tiny sigh of relief.

The bed-shaped bot morphs upon command to sidestep the usual trouble of moving a bedridden person from bed to wheelchair, or vice versa. Yet unlike the Japanese bear bot nurse that carries patients, a self-controlled bed bot allows humans to regain some independence and dignity.

2009 Arctic Sea Ice Extent Exceeds 2005 For This Date

From Watts Up With That?:

While 2009 minimum on 09/13 of 5,249, 844 was just 65, 312 sq km below 2005 in minimum extent, which occurred on 9/22/2005 with 5,315,156 sq km, it has now rebounded quickly and is higher by 38,438 sq km, just 2 days before the 9/22/05 minimum. On 9/22/2009 it may very well be close to 60-80,000 sq km higher than the minimum on the same date in 2005.

From Science Daily:

ScienceDaily (Sep. 22, 2009) — Ninjas knew how to be stealthy: Be dark. Emit very little light. Move in the shadows between bright places.

In modern warfare, though, ninjas would be sitting ducks. Their black clothes may be hard to see at night with the naked eye, but their warm bodies would be clearly visible to a soldier wearing infrared goggles.

Why Autumn Begins Tuesday

From Live Science:

The first day of autumn — Sept. 22 this year — is no guarantee of fall-like weather, but officially the season's start comes around at the same time each year nonetheless.

Well, sort of.

The first day of autumn arrives on varying dates in different years for two reasons: Our year is not exactly an even number of days; and Earth's slightly noncircular orbit, plus the gravitational tug of the other planets, constantly changes our planet's orientation to the sun from year to year.

Discovery Threads Tricky Path Home

From Florida Today:

Navigating a web of clouds and showers, space shuttle Discovery returned home to Kennedy Space Center just after noon Monday atop a 747 jumbo jet, ending a two-day ferry flight from California.

"If it was any greater of a challenge, we wouldn't have landed here," said Charles Justiz, a pilot on the NASA C-9 aircraft that scouted safe routes ahead of the shuttle.

Up to the last minute, more than two hours after departing Barksdale Air Force Base near Shreveport, La., it was uncertain if Discovery might be diverted to MacDill Air Force Base in Tampa or Orlando International Airport to await calmer skies.

From New Scientist:

THEY might be bald and ugly, but naked mole rats never get cancer. If their trick can be copied it could help humans resist cancer too.

It's almost impossible to culture naked mole rat cells in the lab, which made Andrei Seluanov and Vera Gorbunova from Rochester University, New York, wonder if this might be linked to their ability to resist cancer.

They found that a dilute solution of naked mole rat skin cells did start to proliferate, but stopped once the cells reached a certain, relatively low density. Such "contact inhibition" is also used by human cells to inhibit growth, but cancer bypasses this mechanism so cells keep growing.

From The Globe And Mail:

Some experts believe the devices will change our reading habits and throw several industries into turmoil -- that is, just as soon as Apple gets into the game.

Will it or won't it?

The Internet is burning up with speculation about Apple Inc.'s plans for an “iPad,” a potential new entrant in the e-reader market of low-power digital devices whose displays approach paper quality.

Amazon's Kindle and the Sony Reader together cracked the million-unit mark last year, but everyone – especially those in troubled publishing industries – is looking to the iPod maker to potentially bring digital reading into the mainstream, and transform their businesses forever.

A Robot That Juggles Blind

Pendulum Juggler from Philipp Reist on Vimeo.

From Popular Science:

This machine uses no sensors, no feedback -- just the power of math -- to do its tricks.

In theory, designing a robot that continuously juggles a single ball should not be difficult. Calibrating the machine would be a pain but once you got the thing running, it should continue to juggle the ball until some variable intervenes. In a perfect world, this would occur elegantly, but here on Earth things just don't come off so beautifully. However, through some smart design and precise math, researchers at the Swiss Federal Institute of Technology in Zurich have created the Blind Juggler, so named because it juggles a ball continuously, even when variables are introduced, without the use of sensors.
