Hewlett Packard Outlines Computer Memory Of The Future

Image: 17 memristors captured by an atomic force microscope

From The BBC:

The fundamental building blocks of all computing devices could be about to undergo a dramatic change that would allow faster, more efficient machines.

Researchers at computer firm Hewlett Packard (HP) have shown off working devices built using memristors - often described as electronics' missing link.

These tiny devices were proposed 40 years ago but only fabricated in 2008.

HP says it has now shown that they can be used to crunch data, meaning they could be used to build advanced chips.

That means they could begin to replace transistors - the tiny switches used to build today's chips.

Periodic Discussions: It's Going To Take A Long Time For Element 117 To Make It Onto The Periodic Table. Why?

From Slate:

A team of Russian and American scientists announced today the creation of several atoms of the previously unknown element 117. The discovery of "ununseptium" will eventually fill a longtime gap on the periodic table, although that formal change may not happen for years. In June 2009, element 112 was designated as an official element, more than a decade after it was first created. Sam Kean explained why changing the periodic table requires the scientific equivalent of a Supreme Court decision. His column is reprinted below.

From The Guardian:

Alex Bellos selects the maths geniuses whose revolutionary discoveries changed our world.

Pythagoras (circa 570-495BC)

Vegetarian mystical leader and number-obsessive, he owes his standing as the most famous name in maths due to a theorem about right-angled triangles, although it now appears it probably predated him. He lived in a community where numbers were venerated as much for their spiritual qualities as for their mathematical ones. His elevation of numbers as the essence of the world made him the towering primogenitor of Greek mathematics, essentially the beginning of mathematics as we know it now. And, famously, he didn't eat beans.

Fifty years ago today, on April 8th, 1960, a Cornell astronomy professor named Frank Drake pointed a radio telescope at the star Tau Ceti in the hope of hearing broadcasts from extraterrestrial intelligence. Naturally, he didn't hear anything out of the ordinary. But with this experiment, Drake began the decades-long search for aliens, known as the Search for Extraterrestrial Intelligence (SETI), that celebrates its 50th anniversary today. Over the last half century, SETI has failed at its initial goal of contacting aliens, but succeeded mightily in bringing new attention to astronomy, helping to develop cloud computing, and inspiring generations of new scientists.

Better Military Technology Does Not Lead to Shorter Wars, Analysis Reveals

From Science Daily:

ScienceDaily (Mar. 31, 2010) — It is generally assumed that military technology that is offensive rather than defensive in nature leads to shorter wars. Yet, a new doctoral thesis from the University of Gothenburg, Sweden, shows that this assumption is not correct.

For long, researchers have thought that offensive military technology, such as armoured cars and attack jets, makes it easier to shorten the duration of a war. It is also generally perceived that when the offensive technology is more effective than the defensive technology, it is more advantageous to start a war.

From Live Science:

Everyone grumbles when prices at the pump rise, but some drivers pay more depending on where they live. A new study shows how gas price spikes hurt the wallets of drivers in some states more than in others.

On average, Mississippi drivers spent more than 6 percent of their annual income on gas in 2009, compared to drivers in Connecticut and New York who spent just 2.5 percent of their income on gas. But a price spike similar to the one in July 2008 would have worsened the imbalance — Mississippi drivers would have seen driving costs shoot up to 11 percent as opposed to just 4.3 percent for Connecticut and New York.

Oceanology: Tethered Antenna Keeps Subs In Touch

There's a sub below (Image: Brooke Ocean Technology)

From New Scientist:

ROBOTIC submarines have always had trouble when it comes to picking up GPS signals and communicating with their operators. That's because radio signals do not travel far underwater. If the submarines do not surface regularly in order to check their position, they run the risk of drifting off-course.

This problem could now be solved, thanks to a wing-like antenna that piggybacks on small submarines. The antenna ascends to the surface on a tether as and when needed, enabling satellite communications, including GPS readings. It can even carry a camera to serve as a kind of periscope for the sub's controller.

Moral Judgments Can Be Altered

In a new study, researchers disrupted activity in the right temporo-parietal junction by inducing a current in the brain using a magnetic field applied to the scalp. They found that the subjects' ability to make moral judgments that require an understanding of other people's intentions -- for example, a failed murder attempt -- was impaired.

ScienceDaily (Mar. 30, 2010) — MIT neuroscientists have shown they can influence people's moral judgments by disrupting a specific brain region -- a finding that helps reveal how the brain constructs morality.

To make moral judgments about other people, we often need to infer their intentions -- an ability known as "theory of mind." For example, if a hunter shoots his friend while on a hunting trip, we need to know what the hunter was thinking: Was he secretly jealous, or did he mistake his friend for a duck?

Climate change might have helped bring about the fall of the ancient Khmer civilization in Angkor, Cambodia, nearly 600 years ago, new research suggests.

Historians have given various explanations for the fall of the empire that stretched across much of Southeast Asia between the ninth and 14th centuries (801 to 1400), from land overexploitation to conflict with rival kingdoms. But the new study offers strong evidence that two severe droughts, punctuated by bouts of heavy monsoon rain, could have weakened the empire by shrinking water supplies for drinking and agriculture, and damaging Angkor's vast irrigation system, which was central to its economy.

Marine corps engineers in Afghanistan have a new beast of a vehicle to help them defeat explosive booby traps.

The civilian mechanics at Anniston Army Depot in Alabama usually only fix vehicles for the Army, not design them for the Marine Corps. But as Marines push into contested areas of Afghanistan, their engineers face a persistent threat from roadside bombs. The mechanics at Anniston saw they could build a safe ride for these military engineers by adding off-the-shelf equipment to an M1A1 Abrams battle tank. The result, called the Assault Breacher Vehicle (ABV), maximizes the depot staff’s experience at fixing the M1A1 and their ability to mount heavy engineering equipment, including a 12-foot plough, onto its hull. The Army donated excess tank parts from its inventory to create the ABV.
