Oldest Known Paralyzed Human Discovered

The remains of the world's oldest known paralyzed human are excavated in Vietnam. Researchers have found that the man suffered from a rare disorder called Klippel-Feil Syndrome, a condition involving congenital fusion of the spine.

From Discovery:

The remains of a man who could be the world's oldest known paralysis victim have been unearthed by Australian bio-archaeologists in northern Vietnam.

Found at the Neolithic cemetery site of Man Bac, some 100 kilometers (62 miles) south of Hanoi, the remains are between 3,500 and 4,000 years old and belong to an adult male who died around age 25.

Called Man Bac Burial 9, or simply M9, the young man suffered from paraplegia or possibly quadriplegia due to a rare disorder called Klippel-Feil Syndrome, a condition involving congenital fusion of the spine.

Why Exercise Won't Make You Thin

Whether because exercise makes us hungry or because we want to reward ourselves, many people eat more — and eat more junk food, like doughnuts — after going to the gym. Ben Bloom / Getty

From Time Magazine:

As I write this, tomorrow is Tuesday, which is a cardio day. I'll spend five minutes warming up on the VersaClimber, a towering machine that requires you to move your arms and legs simultaneously. Then I'll do 30 minutes on a stair mill. On Wednesday a personal trainer will work me like a farm animal for an hour, sometimes to the point that I am dizzy — an abuse for which I pay as much as I spend on groceries in a week. Thursday is "body wedge" class, which involves another exercise contraption, this one a large foam wedge from which I will push myself up in various hateful ways for an hour. Friday will bring a 5.5-mile run, the extra half-mile my grueling expiation of any gastronomical indulgences during the week.

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.

From San Francisco Chronicle:

From behind their bedroom doors, more than 1 out of every 10 teenagers has posted a nude or seminude picture of themselves or others online - a "digital tattoo" that could haunt them for the rest of their lives, according to a poll being released today.

Aside from the nudity, the survey also found that at least a quarter of the young people polled had posted something they later regretted, made fun of others or created a false identity online.

While teens are spending more and more time on social networking sites like Facebook and MySpace - with 22 percent saying they check their sites more than 10 times a day - they don't seem to be aware of the long-term personal havoc they could create with a click of a button.

From Geekdad/Wired:

We’ve all heard the rumors: Apple is going to be releasing some kind of touchscreen tablet computer, either in September or 1st quarter 2010 (depending upon the source). It could be a fully functioning computer, like a MacBook with a touchscreen, or an extra-large iPod Touch/iPhone. What I do know is that for a geek like me, another little piece of sci-fi futurism from my youth is about to hit the market, and I couldn’t be more excited.

An Operating System For The Cloud

Credit: Brian Stauffer

From Technology Review:

Google is developing a new computing platform equal to the Internet era. Should Microsoft be worried?

From early in their company's history, Google's founders, Larry Page and Sergey Brin, wanted to develop a computer operating system and browser.

They believed it would help make personal computing less expensive, because Google would give away the software free of charge. They wanted to shrug off 20 years of accumulated software history (what the information technology industry calls the "legacy") by building an OS and browser from scratch. Finally, they hoped the combined technology would be an alternative to Microsoft Windows and Internet Explorer, providing a new platform for developers to write Web applications and unleashing the creativity of programmers for the benefit of the masses.

A meteorite that rocked the Sahara

A meteorite that rocked the Sahara desert over 300 million years ago left behind quite a scar that's been photographed before.

New satellite images released by NASA this week provide a closer view of the Aorounga Impact Crater in north-central Chad, one of the best preserved impact structures in the world.

The crater measures 10 miles (17 kilometers) across with a peak that is surrounded by a small sand-filled trough. This feature is surrounded by an even larger circular trough. Winds at the site blow from the northeast and sand dunes formed between the ridges are actively migrating to the southwest. Measuring 10 miles (17 kilometers) across,

Machismo Cuts Men's Lives Short

FROM: LIVE SCIENCE

Why they don't go


Tough guys who buy into ideals of masculinity are much less likely to seek preventive healthcare services, such as a prostate exam, compared with other men.

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.

NOAA Lowers Hurricane Season Outlook

(Click Above Image to Enlarge)
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.

Earth's Most Prominent Rainfall Feature Creeping Northward

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.

Why 'Willy' Could Never Be Free

From Live Science:

In 1998, with much fanfare, a 20-year-old orca named Keiko took a one-way trip on an Air Force cargo plane from Oregon to Iceland. There, attended by dozens of biologists and trainers, and at a cost reportedly topping $20 million, the orca was gradually reintroduced to his native waters.

Keiko, of course, had starred in three "Free Willy" movies, which sparked a public campaign to free him after nineteen years in captivity.

But things didn’t quite turn out as planned.

A team of his former caretakers, led by Malene J. Simon of the Greenland Institute of Natural Resources in Nuuk, has analyzed logs of Keiko’s behavior and data from satellite tags recording his travels and dives. They point out that Keiko never managed to integrate with Icelandic orca pods and didn’t seem to do much diving or fishing. He spent two several-week-long stretches on his own at sea, but ultimately chose to return to human care.

Freak Wave 'Hot Spots' Identified

In 2008, a cargo ship was grounded off Blackpool after being hit by a freak wave.

From The BBC:

Scientists in the US have made a major advance in their understanding of so-called freak waves.

These monster waves present a major risk to ships and offshore platforms.

A computer simulation developed by oceanographers in the US could help locate where and when these "rogue" phenomena are most likely to occur.

The theoretical study shows that coastal areas with variations in water depth and strong currents are hot spots for freak waves.

The history of seafaring is littered with tales of rogue waves capable of rending ships asunder.

Twitter Attack Triggers Conspiracy Theories But Few Seem Plausible

From The Scientific American:

The same week that the Obama Administration lost its acting cyber security czar, cyber attacks torpedoed several of the Web's most popular social-networking sites, in particular Twitter and Facebook. Although the denial-of-service attacks (which overwhelm Web servers with phony requests) were the latest reminder of the difficulties of defending the Web against cyber threats, it appears that these crashed sites were collateral damage in the ongoing conflict between Russia and Georgia. Or were they?

Hurricane Season 2009: Where Are All the Storms?

El Niño conditions over the Pacific Ocean have so far kept a lid on the 2009 Atlantic hurricane season, experts said in August 2009. But there's still plenty of time for a "monster" to form by season's end. Hurricane Andrew, seen above barreling toward Florida on August 24, 1992, also formed during an El Niño year.

From National Geographic:

Before the 2009 Atlantic hurricane season kicked off on June 1, forecasters were calling for 12 named storms, with about half developing into hurricanes.

Now, about two months into the season, zero storms have formed in the Atlantic.

That's because El Niño conditions over the Pacific Ocean have so far kept a lid on the 2009 hurricane season, experts say.

Still, meteorologists warn that a monster hurricane could be spawned before the season ends on November 30.

"Oases of favorable conditions" could exist in the Atlantic Basin long enough to allow a powerful storm to form, said Keith Blackwell, a meteorologist at the University of South Alabama's Coastal Weather Research Center in Mobile.

"It's very plausible that we still could get one or two intense hurricanes this year," Blackwell said. "And it only takes one to make it a bad season."

Virtual Computer Army Takes On The Botnets

From New Scientist:

MORE than 1 million virtual computers are set to provide insight into how networks of infected computers called botnets wreak havoc on the internet, as the Conficker worm did recently.

Ron Minnich and Don Rudish of Sandia National Laboratories in Livermore, California, crammed 250 independent linux "kernels" - the core system of a computer - onto each of 4400 networked Thunderbird machines, creating a total of over 1.1 million individual virtual computers.

While this network cannot mimic the internet's estimated 600 million computers, the duo hope to use it to study how a small number of machines can attack and bring down larger networks. They can also study, for example, why some botnets prefer to be small and others large.
