People Are Still The Weakest Link In Computer And Internet Security, Study Finds


From Science Daily:

Science Daily (Oct. 14, 2009) — Two decades ago, studies showed that computer users were violating best practices for setting up hack-proof passwords, and not much has changed since then. What's clear, say researchers at the University of Wisconsin-Madison and IT University in Copenhagen, is that until human factors/ergonomics methods are applied to the problem, it isn't likely to go away.

Powerful Ideas: Navy Plans Robotic Barnacle Buster

The US Office of Naval Research recently conducted tests with a developmental ship hull grooming robot, called the Robotic Hull Bio-inspired Underwater Grooming (HULL BUG) tool. The HULL BUG is similar in concept to a autonomous robotic home vacuum cleaner or lawn mower and incorporates the use of a biofilm detector that utilizes modified fluorometer technology to enable the robot to detect the difference between the clean and unclean surfaces on the hull of a ship.

From Live Science:

To help save energy on warships, the navy might one day deploy underwater robots that help vessels conserve fuel by scrubbing their hulls clean to make them cut through the water better.

As harmless as barnacles on hulls might seem to landlubbers, these crustaceans generate "increased drag as these ships move from port to port across the world's oceans," explained Office of Naval Research program officer Steve McElvany.

From McClatchy News:

WASHINGTON -- No place seems safe from the prying eyes of inquisitive astronomers.

They've traced the evolution of the universe back to the "Big Bang," the theoretical birth of the cosmos 13.7 billion years ago, but there's still a long stretch of time -- about 800 million years -- that's been hidden from view.

Astronomers call it the Dark Ages, and now they're building huge new radio telescopes with thousands of detectors that they hope will let them peer back into the period, when the first stars and galaxies began turning on their lights.

From The New York Times:

The 1918 flu epidemic was probably the deadliest plague in human history, killing more than 50 million people worldwide. Now it appears that a small number of the deaths may have been caused not by the virus, but by a drug used to treat it: aspirin.

Dr. Karen M. Starko, author of one of the earliest papers connecting aspirin use with Reye’s syndrome, has published an article suggesting that overdoses of the relatively new “wonder drug” could have been deadly.

Dyson’s Blade-Free Wonder Fan



From Gadget Lab:

James Dyson has a fetish for making unusual products: everything from vacuums that suck (in a good way) to hand dryers that blow (also in a good way), each use a clever combo of eye-catching design along with innovative methods of compressing and dispensing air. But even we in the Lab weren’t prepared for the WTF moment when we pulled Dyson’s blade-less Air Multiplier fan from its packaging.

The US Lets Go Of The Internet – Will Anyone Notice?

ICANN relax control over the internet (Image: Stone/Getty)

From The New Scientist:

POLITICAL power is rarely ceded without good reason. So eyebrows were raised last week when the US Department of Commerce decided to relax its grip on the Internet Corporation for Assigned Names and Numbers (ICANN), the body responsible for the naming system that ensures that when you type a web address, your browser knows where to go.

In future, governments and other international organisations will be able to nominate staff to sit on one of ICANN's three newly created steering committees, something the DoC had resisted for years. "What it really means," says ICANN's chief executive Rod Beckstrom, "is that we're going global."

From Time Magazine:

Runny nose, persistent chill, fever, fatigue — these symptoms are all familiar evidence of influenza. But what about a heart attack, suffered 60 years later?

Researchers suggest that such distant health problems may be linked to early exposure to the flu — as early as in the womb — according to a new study that analyzed federal survey data collected from 1982 to 1996. Researchers found, for instance, that people who were born in the U.S. just after the 1918 flu pandemic (that is, people who were still in utero when the disease was at its peak) had a higher risk of a heart attack in their adulthood than those born before or long after the pandemic.

From Technology Review:

Qteros forms a partnership to use sewage as a feedstock for making ethanol.

These days, more and more companies are finding that sewage is a veritable "black gold." In recent years, sewage sludge has been mined for electricity, fertilizer, fish food, and gasoline. Now two companies have partnered up to turn sewage into ethanol. While others have worked to produce ethanol from municipal solid waste, sewage from wastewater has been a relatively unmined ethanol source.

From Live Science:

Although ships sail on the ocean, they can leave tracks in the sky. On Oct. 5, a NASA satellite snapped a shot of this phenomenon forming in a bank of clouds off North America’s west coast.

The white trails look vaguely like the condensation trails, or contrails, left behind by airplanes, but they actually result from ship exhaust.

The Coming E-Reader Wars


Investing In The e-Reader Battle? Bet On Barnes & Noble -- Wall Street Journal

Crazy? That's what Wall Street thinks—analysts love Amazon, but have little to say about its competitor. But that's why buying Barnes & Noble may be a smart move. Some of the best profits come from going against the crowd.

Everybody loves Amazon's booming stock, which has doubled so far this year. But that run-up in value has made it dangerously expensive. By contrast, few adore Barnes & Noble shares, so they've been left for dead. When you run the numbers, the stock looks remarkably cheap.

Building A Bridge Of (And To) The Future

HOLDING UP The Neal Bridge is taking the daily onslaught of traffic in Maine.
Craig Dilger for The New York Times


From The New York Times:

PITTSFIELD, Me. — The Neal Bridge is barely a bump in the road for motorists roaring down Route 100 south of this central Maine town. It’s a modest bit of the nation’s infrastructure — two lanes wide and 34 feet long, enough to span a small stream.

The bridge is newer than most, as suggested by the still-black asphalt and the fresh galvanized gleam of the guardrails. But it’s what is underneath that really makes the bridge stand out.

Peer-to-Peer Passé, Report Finds

From Epicenter/Wired:

Peer-to-peer file sharing has been the bogeyman of the internet, but a new report suggests it’s destined become a fear of the past — replaced by cheap streaming video.

Rising from the ashes in the early 2000s of banned services like Napster, P2P soon became demonized as an imminent threat to software industry, Hollywood and the internet’s backbone, prompting high-profile piracy trials, federal government hearings on traffic management and hand-wringing from ISPs who said torrents of illicit traffic would overwhelm the net.

Flu Vaccines Hit A Wall

From Technology Review:

As new influenza strains emerge, researchers struggle to speed vaccine development.

Making a vaccine against seasonal influenza is a constant catch-up game. Scientists must predict which of the constantly mutating virus strains will be most virulent six months in the future, the amount of time it takes to manufacture the vaccine. The system has worked well enough for the regular flu. But when new, virulent strains emerge--including the current, rapidly spreading swine flu (H1N1)--the traditional approach falls short. Even as consumers clamored for a vaccine, it took seven months and around 48,000 confirmed U.S. cases before the first H1N1 vaccines were shipped to hospitals around the country.
