Porn May 'Shut Down' Part of Your Brain -- Live Science

Watching pornography would seem to be a vision-intensive task. But new research finds that looking at erotic movies can actually quiet the part of the brain that processes visual stimuli.

Most of the time, watching movies or conducting any other visual task sends extra blood flow to this brain region. Not so when the movies are explicit, the researchers found. Instead, the brain seems to shunt blood — and therefore energy — elsewhere, perhaps to regions of the brain responsible for sexual arousal.

Six Out Of Ten Children Download Adult Material

MPs Call For Automatic Block On All Online Porn To Stop The Surge In Children Watching Adult Material -- Daily Mail

* Six out of ten children download adult material

Internet users should automatically be blocked from accessing pornography at home to stop the surge in children seeing adult material, MPs will demand today.

Anyone wanting to view hardcore images online should have to ‘opt out’ of a special filter, according to the panel of MPs and peers looking into child protection.

Their report said that six out of ten children download adult material because their parents have not installed filters. The use of protective filters in homes has fallen from 49 per cent to 39 per cent in the last three years.

A Digital Pearl Harbor Is A Real Possibility

Ex-FBI Cyberexpert: Potential For Digital Pearl Harbor Is Real -- CNET

Shawn Henry talks to CNET about why he left public service and joined a private-sector firm, and he predicts that we will see an attack on critical infrastructure that has physical consequences.

After 24 years with the FBI, Shawn Henry retired late last month from his post as executive assistant director of the Criminal, Cyber, Response, and Service Branch of the agency. Today, he announced that he will be working for security startup CrowdStrike.

In a phone interview with CNET today, Henry discusses what he thinks are the biggest cybersecurity threats facing the country and why the bad guys always seem to be one step ahead.

Hot To Beat A Heart Attack

The Guide To Beating A Heart Attack -- Wall Street Journal

First Line of Defense Is Lowering Risk, Even When Genetics Isn't on Your Side.

Here's the good news: Heart disease and its consequences are largely preventable. The bad news is that nearly one million Americans will suffer a heart attack this year.

Deaths from coronary heart disease in the U.S. have been cut by 75% during the past 40 years. Hospital admissions for heart attack among the elderly fell by nearly 25% in a five-year period during the last decade, a remarkable feat when many experts had expected the aging population to cause an increase in the problem.

How Green Is Your Cloud?

Greenpeace Gives Apple, Amazon Low Marks for 'Dirty' Clouds -- PC Magazine

A Tuesday Greenpeace report that studied the environmental impact of the cloud criticized firms like Apple, Microsoft, Twitter, and Amazon for lagging behind their Web counterparts.

The firms, however, took issue with that characterization.

Amazon, Apple, and Microsoft "are all rapidly expanding without adequate regard to source of electricity, and rely heavily on dirty energy to power their clouds," Greenpeace said in its report, dubbed "How Clean Is Your Cloud?"

Space Shuttle Discovery Over Washington (D.C. Photos)

Space Shuttle Discovery Takes a Tour of Washington, D.C. -- Popular Science

This morning, the space shuttle Discovery, riding atop a 747 shuttle-carrier, flew from Kennedy Space Center in Florida up to Washington, D.C. to its final resting place at the Smithsonian. Along the way it took a tour of the capital, where it was photographed by everyone with a camera, because how often do you see a space shuttle flying around? There aren't any pictures of the shuttle stopping to see the cherry blossoms, but there are plenty of it zooming past Washington landmarks. Check some out in our gallery below.

Spine Tuning: Finding Physical Evidence of How Practice Rewires the Brain -- Scientific American

In kindergarten, several of my friends and I were very serious about learning to tie our shoes. I remember sitting on the edge of the playground, looping laces into bunny ears and twisting them into a knot over and over again until I had it just right. A few years later, whistling became my new challenge. On the car ride to school or walking between classes, I puckered my lips and blew, shifting my tongue like rudder to direct the air. Finally, after weeks of nothing but tuneless wooshing, I whistled my first note.

10 Extreme Alternative Motorcycles

Ryno
This electric unicycle incorporates motorcycle-like steering geometry that uses accelerometers and gyros to accelerate, brake, and help you stay balanced. Anticipated to reach market in early 2013 at $4500, the Ryno offers a 20-mph top speed and an estimated cruising range of 20 miles from its lithium iron phosphate battery. Christopher Hoffman, who heads the Portland, Oreg.–based outfit, says that unlike the Segway, his creation is "very gentle and responsive, and feels like a part of your body. It's weird." We'll say.

10 Extreme Alternative Motorcycles... and One That Flies -- Popular Mechanics

When you think "motorcycle," the image that jumps to mind is probably a Universal Japanese Motorcycle—the silhouette pioneered by these bikes of the '60s came to define what a motorbike looks like. But there's another world of bikes that veers from the norm and embraces the unusual. These offshoots—some open-air, others enclosed—explore everything from backwards trike layouts to V-8 and alternative fuel powerplants.

US Space Shuttle: The End Of An Era

Space Shuttle Discovery Takes Off On Final Voyage To New Museum Home -- The Telegraph

Aboard a modified jumbo jet, Nasa's oldest shuttle takes off from Florida's Kennedy Space Centre bound for its new home at the Smithsonian Institution.

For its last ride, Discovery took off not from its usual seaside launch pad but atop a modified Boeing 747 carrier jet that taxied down the Kennedy Centre's runway at dawn.

The shuttle, which completed its final spaceflight in March 2011, piggybacked on the jumbo jet in order to make its way to the Smithsonian National Air and Space Museum in Virginia.

A Look At The Future Of Books

People looking at an e-book reader app on the Apple iPad.

A Dark Day For The Future Of Books -- CNN

(CNN) -- Wednesday was a dark day for the future of books.

The Department of Justice charged Apple and five large book publishers with conspiring to raise e-book prices. Three of the five publishers quickly capitulated rather than face the risk and expense of a protracted legal battle.

Much of the case revolves around the decision of five of the largest six publishers to simultaneously adopt the agency pricing model immediately before Apple launched the iPad and iBookstore in April 2010. At that time, Amazon commanded about 90% of the e-book market. Amazon priced many books at $9.99 -- which was below the cost at which Amazon was paying the publisher -- in an effort to drive e-book adoption among consumers and capture market share.

Stopping Text Scams On Cell Phones

Hell Phone: Is There Any Way To Stop The Scourge Of Text Message Spam? -- Slate

Two years ago, I got a text message from a number with a Las Vegas area code. “Thanks for visiting our site!” it read. “Claim your $100 Gift card at www.topgiftsnow.com. Gift Code: 13Z76F. To end reply STOP.” Annoyed, I typed “STOP” and hit send. The next day I got another one. “STOP,” I typed again. Then came the deluge. “Clearance pricing on new cars!” my phone buzzed. “Start a career in law enforcement!” “You have 1 unread message from your secret crush!” At first they were all from Las Vegas. Then they were from Oregon, Idaho, and Nebraska. Every buzz meant another text message charge on my bill.

New Treatment For Prostate Cancer Gives 'Perfect Results' For Nine In Ten Men: Research -- The Telegraph

A new treatment for prostate cancer can rid the disease from nine in ten men without debilitating side effects, a study has found, leading to new hope for tens of thousands of men.

It is hoped the new treatment, which involves heating only the tumours with a highly focused ultrasound, will mean men can be treated without an overnight stay in hospital and avoiding the distressing side effects associated with current therapies.

A study has found that focal HIFU, high-intensity focused ultrasound, provides the 'perfect' outcome of no major side effects and free of cancer 12 months after treatment, in nine out of ten cases.

How Did Japan Come To Prefer Wheat Over Rice?

Waves Of Grain: How Did Japan Come To Prefer Wheat Over Rice? -- Slate

Unlike other popular Japanese gadgetry, the Gopan bread maker isn’t sleek, nor does it fit in a trouser pocket. But Panasonic's $600 kitchen aid does boast a trump card: It produces freshly baked loaves from raw, whole grains of rice.* Since its launch in November 2010, the appliance—whose name is an inspired play on gohan, meaning “cooked rice,” and pan, meaning “bread”—has been selling like hotcakes in Japan (the only country where it’s currently available).

The Rapid Rise Of China As A Space Power

China Now Tops U.S. in Space Launches -- Danger Room

For the first time ever, China has launched more rockets into orbit in a year than the U.S. In 2011, the Chinese sent 19 rockets into space. The U.S. sent just 18. Russia, the Walmart of space launches, fired off no fewer than 31 rockets.

The numbers, parsed in recent reports from the U.S. Federal Aviation Administration and the nonprofit Space Foundation, might seem to herald America’s orbital decline relative to its most bitter rival. In terms of sheer numbers of rocket launches, China has been steadily catching up to America for several years. In 2010, China fired off 15 rockets, matching the U.S. for the first time.

My Comment: The trend is for China to surpass even Russia within the next 5-10 years.

Here Comes The Robot Subs

Navy Will Give Nearsighted Minehunter Robotic Glasses -- Danger Room

The Navy is building a fleet of mine-hunting ships that investigators say aren’t all that hot at finding mines. So in the coming years, those ships are going to get drone supplements to dive deep below the sea to spot the underwater weapons. Think of ‘em as pairs of robotic glasses.

This is a scale model of the Navy’s newest drone sub, called the Knifefish. Manufactured by General Dynamics, the Navy unveiled it for the first time on Monday at its annual Sea Air Space convention just outside Washington, D.C.

My Comment: The US Navy is bit late in the drone revolution ... but it appears that they are catching up very quickly.

The Cost Of Britain's Bee Decline

Under threat: Numbers of honeybees in managed hives have fallen by half since the 1980s and wild honeybees are nearly extinct

The Honey Trap: How The Demise Of Britain's Bees Could Cost Us £1.8billion A Year -- Daily Mail

Losing bees would cost Britain £1.8bn to foot the costs of hand-pollinating plants, a study has found.

Researchers at the University of Reading say the decline in their numbers would be disastrous for crops and drive up food prices.

Simon Potts, professor of biodiversity, and his team tested teams hand-pollinating all Britain’s major crops.
