This Person's Job Is To Build Robots


Roboticist: This Is My Job -- Popular Mechanics

As a 12-year-old, Matt Bunting built robots that chased his cat around the house. Now, here's professional roboticist making machines inspired by biology.

When Matt Bunting was 12, he began building robots—simple rovers driven by remote control. His parents were supportive of his hobby, but one member of the household wasn't so thrilled. "I'd make the rovers chase after my cat," Bunting says. "It would hide, so I had to make a robot to invade its privacy!" His robots became more sophisticated, and when he got to the University of Arizona, he built a hexapod with artificial intelligence. Bunting's professor offered him a job in the Robotics and Neural Systems Lab, where the 25-year-old now creates robots inspired by biology. "I knew that this was what I wanted to do, and now I'm doing it," he says. "It's incredible."

Why Drones Will Not Be Taking Over Our Wars (For Now)

Live Fighters Aboard the amphibious assault ship USS Kearsarge, pilots play a key role in shows of force and complex missions. Even as drones become integrated into the fleet, pilots will lead. U.S. Navy/Mass Communication Specialist 1st Class Tommy Lamkin

The Human Element -- Popular Science

Why drones won't be taking over our wars anytime soon.

Early in 2008 on the Black Sea coast, a Georgian drone flying over the separatist enclave of Abkhazia transmitted an instantaneous artifact from the age of human flight—the video record of its own destruction by an attacking fighter jet. What happened that day was born of incendiary post-Soviet politics. The Kremlin backed Abkhazia and was furious that Georgia had bought surveillance drones to watch over the disputed ground. Georgia’s young government flaunted its new fleet, bullhorning to diplomats and to journalists like me what the drones were documenting of Russia’s buildup to war. I remember the Georgian bravado. We have drones. Ha! We have arrived. Tensions led to action. Action came to this: A Russian MiG-29 intercepted one of Georgia’s unmanned aircraft, an Israeli-made Hermes 450, which streamed live video of the fighter swinging into position. The jet pilot fired a heat-seeking missile. Viewed on the drone operator’s screen down below, the missile grew larger and its exhaust plume grew longer as it rushed near. Then the screen went fuzzy. Georgia’s drone was dead.

White Killer Whale Spotted InTthe Wild

"Iceberg" is believed to be the first mature white orca observed

White Killer Whale Adult Spotted For First Time In Wild -- BBC

Scientists have made what they believe to be the first sighting of an adult white orca, or killer whale.

The adult male, which they have nicknamed Iceberg, was spotted off the coast of Kamchatka in eastern Russia.

It appears to be healthy and leading a normal life in its pod.

White whales of various species are occasionally seen; but the only known white orcas have been young, including one with a rare genetic condition that died in a Canadian aquarium in 1972.

Google’s Secret Switch To The Next Wave Of Networking


Going With the Flow: Google’s Secret Switch To The Next Wave Of Networking -- Wired Networking

In early 1999, an associate computer science professor at UC Santa Barbara climbed the steps to the second floor headquarters of a small startup in Palo Alto, and wound up surprising himself by accepting a job offer. Even so, Urs Hölzle hedged his bet by not resigning from his university post, but taking a year-long leave.

He would never return. Hölzle became a fixture in the company — called Google. As its czar of infrastructure, Hölzle oversaw the growth of its network operations from a few cages in a San Jose co-location center to a massive internet power; a 2010 study by Arbor Networks concluded that if Google was an ISP it would be the second largest in the world (the largest is Level 3, which services over 2,700 major corporations in 450 markets over 100,000 fiber miles.)

Daylight Fireball Streaks Over Nevada and California



Daylight Fireball Streaks Over Nevada and California -- Discovery News

When reports about a meteor make headline news in Los Angeles, it's time to pay attention. In fact, anything that isn't associated with a high-speed car chase or the latest celebrity DUI is usually worth paying attention to (take it from me, it doesn't happen very often). But tonight, local news stations are reporting excited eyewitness accounts of a daytime meteor that ripped through the skies above Nevada and California on Sunday morning.

Aspirin: New Evidence Is Helping Explain Additional Health Benefits And Open Potential For New Uses -- Science Daily

ScienceDaily (Apr. 19, 2012) — New evidence is helping explain additional health benefits of aspirin. Researchers in Canada, Scotland and Australia have discovered that salicylate, the active ingredient in aspirin, directly increases the activity of the protein AMPK (AMP-activated protein kinase), a key player in regulating cell growth and metabolism. AMPK which is considered a cellular fuel-gauge is switched on by exercise and the commonly used anti-diabetic medication metformin.

Adult Males Will Soon Have The Same Life Expectancy As Females


Men Will Soon Live Longer Than Women For The First Time As They Ditch Their Unhealthy Lifestyles -- Daily Mail

* Boys born in 2000 will live to 87 - the same as girls
* Younger boys forecast to then outlive their female counterparts
* All due to a decline in heavy industry, fewer smokers and improved healthcare

Men could be about to win the lifelong battle of the sexes – or at least draw even.

Experts say that adult males will soon have the same life expectancy as females for the first time since records began.

By the time today’s 12-year-old boys reach 30, they can expect to live to a month or so over 87 – matching the lifespan of the girls they are in school with today.

New Smart Weapons Will Not Use GPS

DARPA Seeks To Wean Smart Weapons Off GPS With Hybrid Inertial Navigation System-On-A-Chip -- Military & Aerospace

ARLINGTON, Va., 18 April 2012. Navigation and guidance experts at the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., are trying to reduce the military's reliance on Global Positioning System (GPS) satellite guidance for advanced munitions, mid- and long-range missiles, and other weapons by creating a navigation-system-on-a-chip that combines traditional and atomic inertial guidance technology.

iPhone 5 Rumors


Apple iPhone 5 'To Be Cased In Liquidmetal' -- The Telegraph

Apple’s next iPhone will be cased in ‘Liquidmetal’, according to reports.

The iPhone 5, likely to be released later this year, is expected to be cased in a ‘metallic glass’, otherwise known as Liquidmetal, says a Korean news outlet citing ‘industry sources’.

The case is expected to be 20 times stronger than the current encasement. According to The Register, ‘metallic glass is a metal alloy, but one with the disordered structure of glass’. The material has been around since the 1990s, but since a new breakthrough in ‘superspeed pulse mould technology’, this type of glass, which is as tough as metal, can now be used for phone casings.

A Quixotic Quest to Mine Asteroids -- Wall Street Journal

A new company backed by two Google Inc. GOOG -0.54% billionaires, film director James Cameron and other space exploration proponents is aiming high in the hunt for natural resources—with mining asteroids the possible target.

The venture, called Planetary Resources Inc., revealed little in a press release this week except to say that it would "overlay two critical sectors—space exploration and natural resources—to add trillions of dollars to the global GDP" and "help ensure humanity's prosperity." The company is formally unveiling its plans at an event Tuesday in Seattle.

Swedish Stonehenge? Stone Structure Spurs Debate -- Discovery News

A series of 59 boulders placed at a seaside cliff in Sweden might represent Stonehenge's "sister" site.

* An ancient stone structure in Sweden may be 1,500 years older than previously thought.
* New analysis suggests the stones represent an ancient astronomical calendar.
* Some researchers argue the stones were placed with the same underlying geometry of Stonehenge.

Ancient Scandinavians dragged 59 boulders to a seaside cliff near what is now the Swedish fishing village of Kåseberga. They carefully arranged the massive stones -- each weighing up to 4,000 pounds (1,800 kilograms) -- in the outline of a 220-foot-long (67-meter) ship overlooking the Baltic Sea.

'Huge' Water Resource Exists Under Africa


'Huge' Water Resource Exists Under Africa -- BBC

Scientists say the notoriously dry continent of Africa is sitting on a vast reservoir of groundwater.

They argue that the total volume of water in aquifers underground is 100 times the amount found on the surface.

The team have produced the most detailed map yet of the scale and potential of this hidden resource.

Writing in the journal Environmental Research Letters, they stress that large scale drilling might not be the best way of increasing water supplies.

Pentagon And State Support Lifting Some Controls On U.S. Satellite Exports


The Star Fighters -- Washington Free Beacon

Administration report warns that loosening exports on space technology could boost China’s space warfare capabilities.

China is building space weapons designed to defeat U.S. and allied long-range missiles, and U.S. plans to loosen controls on satellite exports likely will boost Beijing’s space warfare programs, according to a Obama administration report made public on Wednesday.

The report warned that if the U.S. government relaxes controls on satellite exports and related items, “China would purchase and acquire more of these items, and in turn, further reduce the technological edge of the United States’ and its allies’ space assets,” the report said.

Engineering Better Hair Transplants -- Science News

Cell-based approach to new follicles takes hold in skin.

A hair-raising trick may lead to better hair transplants. Engineered hair follicles patched into skin can be coaxed to connect to surrounding tissue and to grow hair in an organized way, a study in mice finds.

Unlike current hair transplant methods, which simply move existing hair follicles from one area of the scalp to another to cover a bald region, the approach would spur the creation of new hair follicles from existing cells.

Where Do Brain Waves Come From?: Extract From Jonah Lehrer's Imagine -- The Telegraph

From surfing backwards to improvising a complex song, Jonah Lehrer explains why creativity lies within us all - and the fascinating science that can help us access it.

The search for emotion shapes the way the virtuoso classical cellist Yo-Yo Ma approaches every concert. He doesn’t begin by analysing his part or by glancing at what the violins are supposed to play. Instead, he reviews the complete score, searching for the larger story. “I always look at a piece of music like a detective novel,” Ma says. “Maybe the novel is about a murder. Well, who committed the murder? Why did he do it? My job is to retrace the story so that the audience feels the suspense. So that when the climax comes, they’re right there with me. It’s all about making people care about what happens next.”
