Milky Way 'Clone' Captured By European Astronomers -- The Telegraph

A striking image of a giant Milky Way ''clone'' has been captured by astronomers.

The bird's eye view of NGC 6744 gives a good idea of what our own galaxy would look like to a passing space traveller.

The spiral galaxy is around 30 million light years away in the southern constellation of Pavo, the Peacock.

In the new image from European Southern Observatory astronomers it is seen almost face on, so that the striking spiral arms are clearly visible.

NGC 6744 would almost be an identical twin of the Milky Way were it not for its size.

A Leap Forward For DNA-Based Computers

A wiring diagram illustration depicts a system of 74 DNA strands that constitute the largest synthetic circuit of its type ever made. The circuit can compute the square root of numbers up to 15, though very slowly. (Lulu Qian / Caltech / June 2, 2011)

Research Marks A Leap Forward For DNA-Based Computers -- L.A. Times

A system involving 74 DNA strands can calculate square roots of numbers up to 15, though very slowly. Scientists say the goal is to devise computers that can interact directly with living cells — and perhaps fight disease.

Caltech researchers have produced the most sophisticated DNA-based computer yet, a wet chemistry system that can calculate the square roots of numbers as high as 15.

The system is composed of 74 strands of DNA that make up 12 logic gates comparable to those in a silicon-based computer, the researchers reported Thursday in the journal Science. But the system operates a little more slowly than a conventional computer: It takes as much as 10 hours to obtain each result.

Quantum Entanglement Means Computers Could Cool Themselves By Deleting Information -- Popular Science

But don't wipe your hard drives just yet.

It’s common empirical knowledge that computing generates heat--go ahead, touch the bottom of your MacBook--but a new paper in the journal Nature claims that it doesn’t have to. In fact, under the right conditions, theoretical physicists say that deleting data can actually produce negative heat--that is, it can have a cooling effect. That’s right, this is a quantum mechanics post. Exit now if you don’t want a headache to start the weekend.

Why We Need A Good Night’s Sleep


A Good Night’s Sleep Isn’t a Luxury; It’s a Necessity -- New York Times

In my younger years, I regarded sleep as a necessary evil, nature’s way of thwarting my desire to cram as many activities into a 24-hour day as possible. I frequently flew the red-eye from California, for instance, sailing (or so I thought) through the next day on less than four hours of uncomfortable sleep.

But my neglect was costing me in ways that I did not fully appreciate. My husband called our nights at the ballet and theater “Jane’s most expensive naps.” Eventually we relinquished our subscriptions. Driving, too, was dicey: twice I fell asleep at the wheel, narrowly avoiding disaster. I realize now that I was living in a state of chronic sleep deprivation.

How the Brain Processes Faces: Neural System Responsible for Face Recognition Discovered -- Science Daily

ScienceDaily (June 1, 2011) — Each time you see a person that you know, your brain rapidly and seemingly effortlessly recognizes that person by his or her face.

Until now, scientists believed that only a couple of brain areas mediate facial recognition. However, Carnegie Mellon University's Marlene Behrmann, David Plaut and Adrian Nestor have discovered that an entire network of cortical areas work together to identify faces. Published in the current issue of the Proceedings of the National Academy of Sciences (PNAS), their findings will change the future of neural visual perception research and allow scientists to use this discovery to develop targeted remedies for disorders such as face blindness.

In Search of Habitable Worlds: The Older the Planet, the Greater Chance There's Life -- Time

To date, the Kepler space telescope has found more than 1,200 likely planets orbiting stars beyond the sun — quite a haul for a satellite that's been flying for just over two years. The true prize Kepler is hunting for, of course, is not just any planet, but one that's a twin of Earth — about the size of our world, orbiting in a zone where the temperature range is like ours. All that would make it a prime place to look for life. Finding such a not-too-hot, not-too-cold world is probably just a matter of time, but even then, there will be one more factor to consider: how old the planet is.

The escalator was patented in 1892, and the design hasn’t changed much since then. The landing platforms make entry and exit dicey endeavors—particularly when the moving stairs disappear beneath them, and all manner of clothing and body parts can get stuck. In recent years, escalators have torn the big toe from a Croc-wearing child in Singapore, bucked dozens of riders in Washington, D.C., and strangled a tipsy sushi chef when the hood of his sweatshirt got caught in the gap between the stairs and the landing platform.

800-Mile-Wide Hot Anomaly Found Under Seafloor Off Hawaii -- National Geographic

Findings contradict long-held theory that a plume directly fuels Hawaii.

Hawaii's traditional birth story—that the volcanic islands were, and are, fueled by a hot-rock plume running directly to Earth's scorching core—could be toast, a new study hints.

Scientists say they've found solid evidence of a giant mass of hot rock under the seafloor in the region. But it's not a plume running straight from the core to the surface—and it's hundreds of miles west of the nearest Hawaiian island.

One day last February, a Twitter user in California named Billy received a tweet from @JamesMTitus, identified in his profile as a “24 year old dude” from Christchurch, New Zealand, who had the avatar of a tabby cat. “If you could bring one character to life from your favorite book, who would it be?,” @JamesMTitus asked. Billy tweeted back, “Jesus,” to which @JamesMTitus replied: “honestly? no fracking way. ahahahhaa.” Their exchange continued, and Billy began following @JamesMTitus. It probably never occurred to him that the Kiwi dude with an apparent love of cats was, in fact, a robot.

Massive Storm Erupts On Saturn -- Cosmos

MARYLAND: A giant early-spring storm in Saturn's northern hemisphere - so powerful that it stretches around the entire planet - has been detected.

The rare storm has been wreaking havoc for months and shooting plumes of gas high into the planet's atmosphere, according to data from NASA's Cassini spacecraft and a European Southern Observatory ground-based telescope, that have been tracking its progress

'Dark Energy' Confirmed

The Anglo-Australian telescope was used in the galaxy survey

New Method 'Confirms Dark Energy' -- BBC

First results from a major astronomical survey using a cutting-edge technique appear to have confirmed the existence of mysterious dark energy.

Dark energy makes up some 74% of the Universe and its existence would explain why the Universe appears to be expanding at an accelerating rate.

The finding was based on studies of more than 200,000 galaxies.

How Piano Wires Changed Through Centuries -- Discovery

Since Mozart's time, piano wires have changed in content -- but very little in quality, research shows.

* The wire inside pianos has undergone significant changes between the piano's origins in the early 1700s until the late 1880s.
* Research suggests that piano designers used music wire to reach similar harmonic levels despite working with different metals.
* Piano designers balance tension and stiffness of music wire, but many other factors are considered as well.

Atmosphere Above Epicentre Of Deadly Japan Earthquake Heated Up 'Rapidly' In Days Before Disaster

Satellite images showing changes in the heat of the atmosphere above the epicentre of the March 11 earthquake between March 1 and March 12. The total electron content in the ionosphere increased dramatically before the quake

A Warning Sign? Atmosphere Above Epicentre Of Deadly Japan Earthquake Heated Up 'Rapidly' In Days Before Disaster -- The Daily Mail

* Scientists hope they will one day be able to predict quakes uses air ionisation data.

The atmosphere directly above the fault zone which produced Japan's recent devastating earthquake heated up significantly in the days before the disaster, a study has shown.

Before the March 11 earthquake, the total electron content in a part of the upper atmosphere, called the ionosphere, increased dramatically over the earthquake's epicentre, reaching a maximum three days before the quake struck.

It is believed that in the days before an earthquake, the stresses on geological faults in the Earth's crust causes the release of large amounts of radon gas.

U.S. Special Ops Building Satellites To Track Terrorists Everywhere -- Popular Mechanics

The raid on Osama bin Laden's compound this month highlighted special forces' focus on finding high-value targets. Their hunt extends into space, too. An official with U.S. Special Operations Command has confirmed that his organization is testing tiny satellites that could keep tabs on targets from above.

An official with Special Ops revealed Wednesday that the U.S. recently launched mini-satellites that could clandestinely track high-value targets, like al-Qaida terrorists. "We sent up four satellites to demonstrate passing TTL [tagging, tracking, locating] data," Doug Richardson, a civilian official at U.S. Special Operations Command, told an audience on Wednesday, referring to a December launch of a SpaceX rocket carrying the CubeSats—inexpensive satellites so small they can fit in the palm of your hand, and which have been used for scientific missions for a number of years.

Robots Learning Their Own Language

The 'Lingodroids' Learning Language via IEEE Spectrum

Robots Learn To CreateTheir Own Spoken Language -- Popular Science

Having a computer for a brain has its perks, but it has its drawbacks as well. Language is a tough concept for robots, as words can convey the abstract as well as the concrete and robots have trouble knowing the difference (and grasping the abstract). That makes human-machine interaction less than intuitive for humans and confusing to ‘bots. But Australian researchers are hoping to change that by teaching robots to communicate verbally in a language of their own creation, the same way humans did.

Beware Of The Coming Zombie Apocalypse



Will Budget Cuts Leave Us Unprepared For Zombie Apocalypse? -- ABC News

If zombies ever start taking over the planet, the U.S. Centers for Disease Control and Prevention (CDC) says we'd better be prepared for it.

If the undead really start roaming the earth looking for fresh brains to eat, we can't rely on our ability to shoot 'em dead the way people do in video games or in horror flicks. Instead, the agency says, we need to treat it like any other disaster.
