Transparent Memory Chips – The Next Step in Memory Storage -- Sci-Tech Daily

As technology moves forward, things get smaller, faster and now possibly transparent. A team of scientists have developed transparent, flexible memory chips that may one day replace flash drives and other personal data storage devices.

New memory chips that are transparent, flexible enough to be folded like a sheet of paper, shrug off 1,000-degree Fahrenheit temperatures — twice as hot as the max in a kitchen oven — and survive other hostile conditions could usher in the development of next-generation flash-competitive memory for tomorrow’s keychain drives, cell phones and computers, a scientist reported today.

Dolphins 'Resort To Rape' -- The Telegraph

Dolphins appear to have a darker side, according to scientists who suggest they can resort to 'rape' to assert authority.

Researchers found the marine mammals lead complex social lives, living in an "open society" where regular homosexual and bisexual relationships are found.

The conclusions from the international team of scientists came after they spent the past six years studying the behaviour of 120 bluenose dolphins in Shark Bay, Western Australia.

Future Wars Will Be Fought By Hackers

Clarke has seen the future of war and says it will be fought by hackers. Khue Bui

Richard Clarke On Who Was Behind the Stuxnet Attack -- Smithsonian

America's longtime counterterrorism czar warns that the cyberwars have already begun—and that we might be losing.


The story Richard Clarke spins has all the suspense of a postmodern geopolitical thriller. The tale involves a ghostly cyberworm created to attack the nuclear centrifuges of a rogue nation—which then escapes from the target country, replicating itself in thousands of computers throughout the world. It may be lurking in yours right now. Harmlessly inactive...or awaiting further orders.

A great story, right? In fact, the world-changing “weaponized malware” computer worm called Stuxnet is very real. It seems to have been launched in mid-2009, done terrific damage to Iran’s nuclear program in 2010 and then spread to computers all over the world.

My Comment:
This is a long read .... but it is comprehensive and thoughtful. As to what is my take on the future of war .... in a way I do agree with Mr. Clark's assessment. Future wars will be fought (in some capacity) by hackers who will also have their own "army of ninjas" to use when needed.

Dolphin's Social Lives More Complicated Than First Thought

Dolphins Lead ‘Complicated’ Social Lives -- ABC News

In what can only be described as “West Side Story” meets “Flipper,” scientists say they’ve discovered that male bottlenose dolphins break out into gangs to protect their females.

The researchers from the University of Massachusetts, Dartmouth, studied more than 120 adult dolphins, with a focus on the males, during a five-year period in Shark Bay, western Australia.

Their findings were published in the Royal Society journal Proceedings B.

Amazon CEO Finds Apollo 11 Engines In Ocean -- CBS

LOS ANGELES - For more than four decades, the powerful engines that helped boost the Apollo 11 mission to the moon have rested in the Atlantic. Now Internet billionaire and space enthusiast Jeff Bezos wants to raise at least one of them to the surface.

An undersea expedition spearheaded by Bezos used sonar to find what he said were the F-1 engines located 14,000 feet deep. In an online announcement Wednesday, the Amazon.com CEO and founder said he is drawing up plans to recover the sunken engines, part of the mighty Saturn V rocket that launched Neil Armstrong, Buzz Aldrin and Michael Collins on their moon mission.

Telepresence Robots Will Soon Join Doctors On Their Rounds

CtrlWorks' Telepresence Puppet CtrlWorks

Telepresence Robots Will Join Doctors on Their Rounds in Singapore Next Month -- Popular Science

Deploying telepresence robots in a medical setting isn’t exactly a new notion, but a Singapore-based startup is easing the technology into the clinical setting in a clever way. While other telepresence platforms have largely focused on allowing doctors to examine patients and oversee care remotely, CtrlWorks envisions its Puppet as more of a remotely piloted assistant that will reduce doctor workloads, dutifully taking down case notes and filing them in the proper places as a doctor makes his rounds. And next month at Khoo Teck Puat Hospital in Singapore it will get a chance to prove its value.

Who Screens The Pilots?

Are Airline Pilots Screened For Mental Health? -- Air & Space Smithsonian

The case of the ranting JetBlue captain—who went berserk when his co-pilot locked him out of the cockpit after noticing erratic behavior—got us wondering: how are airline pilots tested for soundness of mind?

Although the Federal Aviation Administration requires physicals every year for commercial pilots under 40 and every six months for those older, the FAA does not require psychological checks. The FAA-approved doctors order testing only if they think a pilot needs it.

My Comment: After what happened with a JetBlue captain this week .... psychological screenings will probably soon become the norm.

Life Brought To Earth By Comets -- The Telegraph

Life on Earth may have been sparked by comets carrying with them the key ingredients for our existence, scientists claim.


NASA scientists have replicated the impact of a comet and demonstrated that amino acids, a building block of life, could have survived the intense heat and shock waves given off in the collision.

The combination of water, energy and amino acids – which bind together to form proteins – could have caused the first chemical reactions and created proteins, the researchers said.

Drone Aircraft Are No Longer Restricted To Military Use


Unblinking Eyes In The Sky -- The Economist

Technology and society: Drone aircraft are no longer restricted to military use. They are being built and used by hobbyists, activists and estate agents, among others. What are the implications for safety and privacy?

WHEN environmental activists start using drones to track down Japanese whaling vessels, as they did in December, it is a sure sign that UAVs (unmanned aerial vehicles) are no longer the sole prerogative of the armed forces. Police around the world are keen to use small pilotless aircraft to help them nab fleeing criminals and monitor crime scenes from above. With price tags of a little more (and, in some cases, a good deal less) than the $40,000 of a patrol car, a new generation of micro-UAVs is being recruited to replace police helicopters costing $1.7m and up.

U.S. Heavily Dependent On Military Space Technology

Hearings Show Our Dependence On Military Space Technology -- Washington Post

The United States may be falling behind in transportation, education and health care down here on Earth, but its military infrastructure is certainly way ahead when it comes to imagery and communications satellites armed with defensive and offensive capabilities out there in space.

That the United States leads in the militarization of space is apparent from House and Senate Armed Services subcommittee hearings this month on the fiscal 2013 budget of $9.7 billion for military space programs.

Jupiter Helps Halley’s Comet Give Us More Spectacular Meteor Displays -- Science Daily

ScienceDaily (Mar. 27, 2012) — The dramatic appearance of Halley's comet in the night sky has been observed and recorded by astronomers since 240 BC. Now a study shows that the orbital influences of Jupiter on the comet and the debris it leaves in its wake are responsible for periodic outbursts of activity in the Orionid meteor showers. The results will be presented by Aswin Sekhar at the National Astronomy Meeting in Manchester on the 27th of March.

Halley's comet orbits the Sun every 75-76 years on average. As its nucleus approaches the Sun, it heats up and releases gas and dust that form the spectacular tail. This outgassing leaves a trail of debris around the orbit.
