No Surprise: Coed Dorms Fuel Sex and Drinking


From Live Science:

It's no secret to students that coed dorms are more fun than same-sex dorms. But they can also fuel very unhealthy behavior that might otherwise be moderated.

A new study finds university students in coed housing are 2.5 times more likely to binge drink every week. And no surprise, they're also likely to have more sexual partners, the study found. Also, pornography use was higher among students in coed dorms.

Some 90 percent of U.S. college dorms are now coed.

From The Guardian:

X-rays of mummies reveal atherosclerosis, suggesting there may be more to heart disease than bad diet and smoking.

Heart disease plagued human society long before fry-ups and cigarettes came along, researchers say. The upper classes of ancient Egypt were riddled with cardiovascular disease that dramatically raised their risk of heart attacks and strokes.

Doctors made the discovery after taking hospital X-ray scans of 20 Egyptian mummies that date back more than 3,500 years.

From Time Magazine:

There was a time when Wendy and her husband had sex three times a week. But for the past six years, the purple negligee that Wendy used to entice her husband has been stuffed in the back of a drawer. And now, instead of getting hot and bothered by her husband's advances, Wendy is simply bothered. "All of a sudden I didn't have any desire. There's just nothing there anymore," says Wendy, who requested that her last name not be published.

From The Christian Science Monitor:

Web widgets bring Internet perks to the biggest screen in most people’s homes.

The Internet revolution may finally be televised.

Innocuous little software applications, popularly known as “widgets,” may turn out to be the back door to your TV screen that Internet companies have been waiting for.

For more than a decade, businesses have been trying to make the Internet available on the largest screen in most homes. In 1996, Time Warner offered WebTV, which failed to find an audience and folded. Even today, projects like Hewlett Packard’s MediaSmart (2006) and Apple TV (2007) have yet to win over large numbers of viewers, hampered by complicated setups or limited programming choices.

Innovation: The Dizzying Ambition Of Wolfram Alpha

From New Scientist:

When the search engine Wolfram Alpha launched earlier this year, the interest was huge. Enticed by a well-oiled publicity machine, web users swamped the site and its servers were overwhelmed. Then everything went quiet – so quiet that it was easy to imagine that Alpha would follow countless Google wannabes to the great search engine directory in the sky.

That was to reckon without Stephen Wolfram, a physicist famous for creating and selling the mathematics software Mathematica and for his pioneering but controversial work on cellular automata.

The Top 8 Dinosaur Discoveries of 2009

(Torsten Blackwood/AFP/Getty Images)

From Popular Mechanics:

Paleontologists have had a good year, bringing a slew of new dinosaurs to the books. We pored through the many finds to bring you the best horned, bird-footed, feathered and, of course, ferocious new dinosaurs unveiled this year.

In science, it's exceedingly rare when the naked eye usurps modern technology—powerful telescopes offer humans unprecedented views of celestial phenomena, surgeons can send tiny cameras inside your intestinal tract and even iPhone apps can spot public restrooms before you can. However, for the paleontologists who routinely discover new dinosaurs, a good set of eyes, geological know-how and a little luck remain the best tools.

Spanish Scientists Mod Optical Mouse Into Counterfeit Coin Detector

Counterfeit Coin Detector Tresanchez et al., via EurekAlert

From Popular Science:

Counterfeiting is as old as money itself, with the history of currency including a millennia-long arms race between mints and the forgers that copy them. While governments have finally crafted paper money so intricate that counterfeiting isn't a major problem, detecting counterfeit coins remains a challenge. Now, Spanish scientists have modified a regular optical computer mouse to create a cheap and easy device for sniffing out phony Euro coins.

Ancient Weapons Dug Up by Archaeologists in England

Over 5000 worked flints came from one small area, including flint cores used for tool creation, blades, flakes and 'debitage' (small chips from tool-working), and scrapers, piercers and microlith tools with the latter being used in composite arrowheads.

From Science Daily:

Science Daily (Nov. 17, 2009) — Staff at the University of Leicester Archaeological Services (ULAS) have been excited by the results from a recently excavated major Prehistoric site at Asfordby, near Melton Mowbray, Leicestershire. The Mesolithic site may date from as early as 9000 BC, by which time hunter-gatherers had reoccupied the region after the last ice age. These hunters crossed the land bridge from the continental mainland -- 'Britain' was only to become an island several thousand years later.

The Future of Evolution: What Will We Become?

Could humans split into two species? Perhaps, if we engineer one or if a colony is isolated in outer space. Image credit: stockxpert

From Live Science:

Editor's Note: This is the last in a 10-part LiveScience series on the origin, evolution and future of the human species and the mysteries that remain to be solved.

The past of human evolution is more and more coming to light as scientists uncover a trove of fossils and genetic knowledge. But where might the future of human evolution go?

There are plenty of signs that humans are still evolving. However, whether humans develop along the lines portrayed by hackneyed science fiction is doubtful.

Vaccines On Horizon For AIDS, Alzheimer's

From Time Magazine:

(MARIETTA, Pa.) — Malaria. Tuberculosis. Alzheimer's disease. AIDS. Pandemic flu. Genital herpes. Urinary tract infections. Grass allergies. Traveler's diarrhea. You name it, the pharmaceutical industry is working on a vaccine to prevent it.

Many could be on the market in five years or less.

Contrast that with five years ago, when so many companies had abandoned the vaccine business that half the U.S. supply of flu shots was lost because of contamination at one of the two manufacturers left.

Interview: The Man Who Makes Killer Robots For The US Military


From CNET:

It sounds like the opening scene of a Terminator movie: a team of intelligent air, land and sea robots working together to hunt down a group of human soldiers. Detected by infrared sensors mounted on a cyber-jetski, the platoon is forced to take shelter in a beach bunker. Stealthy flying drones then co-ordinate an attack, flushing the panicked warriors right into the arms of a pair of tracked and armed ground robots. Game over, man.

Don't Pack Your Parachute: Totally Free Fall



From New Scientist:

ON A bright day in 1912, an Austrian tailor named Franz Reichelt jumped off the Eiffel Tower in Paris, France. This was no suicide attempt. Reichelt was wearing a special overcoat of his own design that was supposed to let him glide gently to the ground. Sadly, it didn't work. As the crowd watched and movie cameras whirred, the "flying tailor" plunged 60 metres to his death.

Top 10 Languages On The Internet

From Discovery News:

f the Internet is the new public square, it's crowded and noisy. More than 1.4 billion people gather and talk on its cyber sidewalks.

Despite all those tongues, it's not a very linguistically diverse place.

More than half are in three languages: English, Chinese and Spanish.

Compare that to the number of known languages, 6,912 according to Ethnologue.com, and residency in the online neighborhood seems wildly exclusive.

A Case In Antiquities For ‘Finders Keepers’

Viktor Koen

From New York Times:

Zahi Hawass regards the Rosetta Stone, like so much else, as stolen property languishing in exile. “We own that stone,” he told Al Jazeera, speaking as the secretary general of Egypt’s Supreme Council of Antiquities.

The British Museum does not agree — at least not yet. But never underestimate Dr. Hawass when it comes to this sort of custody dispute. He has prevailed so often in getting pieces returned to what he calls their “motherland” that museum curators are scrambling to appease him.
