Does Pumping Groundwater Raise Sea Levels?

For many crops around the world, farmers must supplement rainfall with irrigation — and much of this added water comes from underground reservoirs. Globally, extraction rates now greatly exceed that of groundwater recharge, and have begun raising sea levels.Cinoby/Istockphoto

Pumping Groundwater Raises Sea Level -- Science News

Two new studies flag an underreported factor in global ocean change.

Pumping groundwater, some 70 percent of it to irrigate crops, has recently become a potent force in global sea-level rise, two new studies conclude.

It sounds obvious: Once brought to the surface, water will eventually run into the seas, says hydrologist Yoshihide Wada of Utrecht University in the Netherlands. But until now, most major assessments of factors affecting sea-level rise — such as those reported by the Intergovernmental Panel on Climate Change — ignored the role of groundwater extraction, he says. For instance, the IPCC has assumed that groundwater extraction would be largely balanced by river water impounded by dams.

My Comment:
If true .... this is a serious problem. Especially since much of our food is produced using irrigated water.

How Apple and Microsoft Armed 4,000 Patent Warheads -- Wired Enterprise

In many ways, Scott Widdowson is your typical electrical engineer. Most days, when the weather’s good, he bikes the 15 miles along the Ottawa River to his company’s offices in the west end of the Canadian capital. Once there, he settles in for a day of reading technical specifications, poring over computer textbooks, or prying apart consumer electronics — logic probe in one hand and a soldering iron in the other.

Why Does Everyone Climb Everest In May? -- Popular Mechanics

This past weekend, scores of adventurers tried to ascend the world's tallest peak—and not all of them made it alive. We asked a geographer who's climbed Everest why this is about the only time of the year to try it and whether he saw any bodies on his trip to the top.

The AP reported this morning that three climbers who attempted to scale Mount Everest this weekend died and that two more were still missing. But about 150 climbers managed to summit the world's highest peak on either day—including a 73-year-old who became the oldest woman to reach the zenith.

Why is everyone ascending Everest in May? To find out, and to get other answers to our questions about Everest, we talked to John All, a geographer at Western Kentucky University. All climbed Everest in 2010 via the Northeast ridge and has spent a year collecting data on climate change at Nepal's base camp.

Doomed Mercury-Sized Exoplanet May Be Turning to Dust -- Universe Today

The old saying of the universe being stranger than we can imagine definitely applies to a newfound exoplanet orbiting a star about 1,500 light years from Earth. Researchers using the Kepler space observatory have detected what appears to be a planet about the size of Mercury literally turning to dust. A long tail of debris — almost like a comet’s tail — is following the planet as it whirls around the star, KIC 12557548. Scientists think the planet could be evaporating under the blistering heat of the star, and that by analyzing the dust, they could decipher the history of the planet. But they better hurry. According to the team’s calculations, the planet will completely disintegrate within 100 million years.

With Telerobotics, Astronauts Orbit Mars While Robots Explore the Surface -- Popular Science

Humans could avoid the dangers of landing on Mars.

Getting humans to Mars is a challenge in several steps, with the most difficult and dangerous likely to be the descent. Landing safely on another world is hard for a rover, let alone a spacecraft carrying people. But telerobotics could offer a unique alternative — send the people to the planet, but keep them in orbit, and deploy robots to the surface to do the difficult stuff.

My Comment: You probably can use robots to explore the surface of Mars .... but lets face it .... having a living person is far more "exciting and attention grabbing" than having a machine do it.

Disputed Dinosaur Fossil Auctioned For $1M In NYC -- CBS

NEW YORK — A dinosaur dispute is brewing between the Mongolian government and an American auction house, which sold a fossil of a fearsome T. Rex relative despite a court order not to.

The 8-foot-tall, 24-foot-long skeleton of a Tyannosaurus bataar — or tarbosaurus, a name that means "alarming lizard" — went for $1,052,500 Sunday at a New York auction, says Heritage Auctions, which hasn't identified the buyer or seller. But the sale is contingent on the outcome of the Dallas-based auction house's court fight with Mongolian President Elbegdorj Tsakhia, the auction house said.

'Ring Of Fire' Solar Eclipse Wows Millions



Spectacular 'Ring of Fire' Solar Eclipse Wows Millions -- Space.com

Skywatchers by the millions looked up Sunday (May 20) when the moon hid most of the sun in a rare solar eclipse that created a dazzling "ring of fire" that was visible from Asia to the United States.

An estimated 6.6 million Americans, alone, lived along the U.S. path of the solar eclipse, with millions more soaking in the sight from across southern China and Japan. While spectators along a narrow track saw the moon block out up to 94 percent of the sun, leaving a bright ring round the edges, many other viewers across a wider region reveled in partial solar eclipse views.

Google Chrome Beats Internet Explorer To Become World's Most Popular Web Browser -- The Telegraph

The latest figures reveal that Google Chrome has now overtaken Internet Explorer to become the most widely used web browser in the world.

Google Chrome briefly became the world's most popular web browser for one weekend in March, but according to figures from Statcounter it has now overtaken Microsoft's Internet Explorer for the foreseeable future.

Chrome has beaten a trend that indicated it was going to surge past IE later this summer. The March figures were dismissed as inaccurate by Microsoft, but even so there is a longer-term trend of users choosing Chrome when they can decide for themselves, while business IT departments favour IE.

WHO To Declare Global Polio Emergency


World Health Organisation To Declare Global Polio Emergency -- The Telegraph

The World Health Organisation is expected this week to declare polio a global health emergency as it battles complacency in an attempt to eradicate the deadly virus forever.

This year has seen a decline in cases but health officials say they have only half the funding they need to wipe out the disease in its last three remaining havens — Pakistan, Afghanistan and Nigeria.

Sona Bari, spokeswoman for the polio eradication programme at the World Health Organisation, said the world faced a “now or never” moment.

Can We Trust Killer Robots?

Could We Trust Killer Robots? -- Wall Street Journal

A drone may never have a sense of morality, but it might perform better than a human soldier in sparing the innocent.

In the year 2015, somewhere over the tribal territories of Pakistan, an American MQ-9 Reaper drone patrols a complex "kill zone"—an area of terrorist activity in which large numbers of civilians are also present. But on this mission, the drone isn't piloted from afar. It's on its own.

The aircraft moves closer to gather information about a potential target. Infrared cameras, heat sensors and other tools of surveillance determine whether the target is indeed a militant, examining, for instance, whether he seems ready to attack. The drone's computer system ranks the suspect on a scale from -1 (a noncombatant) to +1 (a confirmed combatant). Having determined that no children or other civilians are in the vicinity, and that everything else is in order, it chooses a weapon and fires. It then assesses the damage and either fires again or, if the enemy is dead, continues its patrol.

My Comment: Such weapon systems will perform according to what their designers plan .... so yes .... we can trust them .... but to a point .... more specifically .... those who program such systems are the ones who will be held accountable if things go wrong.

SpaceX Rocket Launch Aborted In Last Half-Second



ABORT! Embarrassment As Historic Launch Of First Private Mission Into Space Is Cancelled Just A SECOND Before Lift-Off -- Daily Mail

* Launch delayed after 'computer problems' on board commercial rocket
* Trip is first time private firm have sent flight to International Space Station
* Launch of $133m flight now delayed until Tuesday

A private space cargo firm's historic launch to the International Space Station descended into chaos this morning when the mission was abandoned just one second before lift-off.

The unmanned SpaceX Falcon 9 rocket was set to blast off from Cape Canaveral just before 10am this morning (GMT) along with its Dragon capsule loaded with 1,000lbs of space station provisions.

But with just seconds before the rocket took to the skies, apparent technical problems left it rooted to the launch pad, with lift-off subsequently abandoned for another three days.

US At Risk Of 'Catastrophic Cyber-Attack'

US At Risk Of 'Catastrophic Cyber-Attack' Says Intelligence Panel Chairman -- The Hill

The United States is woefully unprepared to counter a “catastrophic cyber-attack” that's expected within 12 to 24 months, House Intelligence Committee Chairman Mike Rogers (R-Mich.) said Thursday.

The House has been doing its part, Rogers said, easily passing his cybersecurity bill last month while his own committee on Thursday adopted its spending bill for fiscal 2013 by a unanimous 19-0 vote. But the White House, citing privacy concerns, has issued a veto threat against the legislation that would allow the government to inform private companies about impending cyber-attacks.

Memristors: A Different Kind Of Computer Memory Chip

Memristors employing more "exotic" materials will probably make it into devices first

Memristors In Silicon Promising For Dense, Fast Memory -- BBC

Researchers have revealed details of a promising way to make a fundamentally different kind of computer memory chip.

The device is a "memristor", a long-hypothesised but only recently demonstrated electronic component.

A memristor's electronic properties make it suitable for both for computing and for far faster, denser memory.

Researchers at the European Materials Research Society meeting now say it can be made much more cheaply, using current semiconductor techniques.

How Exercise Affects The Brain

How Exercise Affects The Brain: Age And Genetics Play A Role -- Science Daily

ScienceDaily (May 18, 2012) — Exercise clears the mind. It gets the blood pumping and more oxygen is delivered to the brain. This is familiar territory, but Dartmouth's David Bucci thinks there is much more going on.

"In the last several years there have been data suggesting that neurobiological changes are happening -- [there are] very brain-specific mechanisms at work here," says Bucci, an associate professor in the Department of Psychological and Brain Sciences.

From his studies, Bucci and his collaborators have revealed important new findings:

Did North Korea's GPS Jamming Cause A Drone Crash?


GPS Loss Kicked Off Fatal Drone Crash -- New Scientist

Hopes that a new breed of commercial drones can be easily integrated into civilian airspace have been dashed after it was revealed that the loss of the technology likely to make it all possible - automatic GPS navigation between waypoints - led to a fatal accident last week.

The news comes after the maker of a surveillance drone that crashed into its control truck in Incheon, South Korea on 10 May, killing one of the company's engineers and injuring the two remote pilots, has confirmed that loss of the aircraft's GPS signal was an initiating event in the accident.

Solar Eclipse Visible From California To Texas This Sunday


Solar Eclipse Visible From California to Texas Sunday Afternoon -- ABC News

If you live in a band across the southwestern United States, twilight will seem to come early on Sunday afternoon, well before the sun actually sets.

The cause: a rare annular solar eclipse -- a ring of sunlight as the new moon, passing between Earth and the sun, blocks most, but not all, of the sun's disc.

This is not the kind of total eclipse of which you usually see pictures -- the moon blocking the sun completely, creating a few moments of near-night in the middle of the day, with only the sun's ethereal corona visible around the moon's edges. The sky will darken a bit, but there will still be a blindingly bright ring (an "annulus" in Latin) of sun, and it's dangerous to look directly at it.
