SETI 2060, Do We Make Contact By Then?

From Discovery News:

This month the National Radio Astronomy Observatory’s Green Bank Science Center is celebrating the 50th anniversary of the modern day search for extraterrestrial intelligence (SETI).

In 1960 a young radio astronomer, Frank Drake, undertook a bold and visionary experiment: He used the 85-foot dish antenna at Green Bank, W.V. to listen for radio signals from extraterrestrial civilizations.

Drake recently retired from the SETI Institute in Palo Alto, Calif., without finding his aliens. He’s not alone. As early as the turn of the last century Nicola Tesla and the father of radio, Guglielmo Marconi, were independently listening for signals from Martians.

Nasa Tests Robot Hardware For Planet Missions

A suit port allows astronauts to be on the surface within a few minutes

From The BBC:

Nasa is testing the next generation of human spaceflight technology in the deserts of Arizona, US.

The Desert RATS (Research and Technology Studies) programme is designed to give advanced equipment a trial run, and to expose any issues before it is used in space.

The dry, dusty, rocky land near the lip of the Grand Canyon provides a good simulation of other planets.

"The terrain is very varied, and is very volcanic in nature, which more or less represents what you would see on the Moon" says Joe Kosmo, Mission Manager for the Desert RATS programme.

Airbus Engineers' Plan For The Future Of Flying

From Der Spiegel:

What will air travel look like in the year 2050? A special team of engineers from European aircraft manufacturer Airbus have drafted plans for the future of flight. These include a completely transparent fuselage that will allow passengers to the see the stars above and city lights below.

The airplane dissolves into thin air, as if erased by an invisible hand. First the cabin roof disappears, then the floor, and from one moment to the next, the passengers feel like they have lost their grip on anything solid.

The Ultimate Field Guide to Subatomic Particles

From io9:

Muons, neutrinos, supersymmetric partners, the infamous Higgs boson - with so many different subatomic particles flying about, it's no wonder theoretical physics can be so confusing. That's why we made this (reasonably) simple guide to all the different elementary particles.

This is, as you might imagine, a pretty big topic, so we're splitting it into (at least) two posts. Today we're going to deal with just the particles that physicists are certain (or, at least, reasonably certain) exist, and then tomorrow we'll get into the even stranger world of particles that have been hypothesized but may or may not actually exist. I've also made a handy cheat sheet listing all the elementary particles and their vital statistics, which you can find here. But to understand what all of that means, you'll really want to read on.

A New Generation Of Helicopters Are Smashing Speed Records

Faster Helicopters More Rotors, More Speed -- The Economist

A new type of helicopter breaks speed records.

THE ability of a helicopter to hover and land almost anywhere makes it an enormously useful machine. But helicopters have their limitations, particularly when it comes to flying fast. In a recent series of test flights, a new type of chopper has begun smashing speed records.

From Science Daily:

ScienceDaily (Sep. 19, 2010) — Deleting a certain gene in mice can make them smarter by unlocking a mysterious region of the brain considered to be relatively inflexible, scientists at Emory University School of Medicine have found.

Mice with a disabled RGS14 gene are able to remember objects they'd explored and learn to navigate mazes better than regular mice, suggesting that RGS14's presence limits some forms of learning and memory.

From Tech News Daily:

Boeing has signed a deal to deploy remote sensing technology to map out U.S. deposits of rare earth elements.

The rare earth family of minerals is the real-life version of the precious element "unobtanium" in James Cameron's movie "Avatar." They are used to make everything from military hardware to humble cell phones, but could soon be in short supply as worldwide demand outstrips mining production in China.

From Cosmos:

GENEVA: The protective ozone layer in the Earth's upper atmosphere has stopped thinning and should largely be restored by mid century thanks to a ban on harmful chemicals, U.N. scientists said.

The "Scientific Assessment of Ozone Depletion 2010" report said a 1987 international treaty that phased out chlorofluorocarbons (CFC) - substances used in refrigerators, aerosol sprays and some packing foams - had been successful.

From Environmental Graffiti:

We all know that there are sights on earth regarded as the Wonders of the World – whether ancient or modern – sights such as the Great Pyramids of Giza, the Taj Mahal, or the Grand Canyon in Colorado with its awesome grandeur. These are not, however, necessarily the sights you have to see, because the word 'wonder' can apply to so many other locations around the globe. Here are a selection of stunning places to see, if you ever get the chance.

The New Twitter Isn't Nearly New Enough

From Daily Finance:

As a Twitter user, I was interested in seeing just how different Twitter.com's new incarnation actually is, especially because it's been billed as the most significant product release for the micro-messaging service in a long time.

Would it finally give me a reason to ditch my Twitter client and go back to Twitter.com? Would it finally produce a revenue model commensurate with the company's stiff venture capital valuation and immense promise? Would it leap tall buildings in a single bound? Alas, none of the above. The new Twitter is fairly tame -- and fairly indicative of the troubles that have beset the popular but not easily monetizable company.

Samsung Galaxy Tab Coming to All Four Major U.S. Carriers

From The Daily Tech:

AT&T, Sprint, T-Mobile, and Verizon will all get version of the Galaxy Tab

Following in the footsteps of the Galaxy S which has made its way to Sprint (Epic 4G), Verizon (Fascinate), T-Mobile (Vibrant), and AT&T (Captivate), Samsung announced today that its 7" Galaxy Tab will also find a home on all four of the major U.S. wireless carriers.

Samsung's all or nothing approach with the Galaxy S smartphone chassis has paid off greatly as the company announced sales of one million phones within the first 45 days of ability. This figure didn't even take into consideration the Verizon Fascinate which hadn't yet been launched at the time of that announcement.

From Physorg.com:

(PhysOrg.com) -- Sunspot formation is triggered by a magnetic field, which scientists say is steadily declining. They predict that by 2016 there may be no remaining sunspots, and the sun may stay spotless for several decades. The last time the sunspots disappeared altogether was in the 17th and 18th century, and coincided with a lengthy cool period on the planet known as the Little Ice Age.

US Assessment Of Terrorist Threats Poor, Says Panel

From New Scientist:

Only "low confidence" should be placed in most of the risk analyses of terrorist threats conducted by the US Department of Homeland Security, concludes a review by a National Research Council panel.

Created after the 9/11 attacks to cover national perils ranging from terrorism to natural disasters, the DHS got off to a rough start. Critics blasted its lack of attention to natural disasters after its bungled response to hurricane Katrina.

Yet the panel finds that DHS models for natural disaster risks are "near the state of the art" and well suited to assess the effects of earthquakes, floods and hurricanes.

From New Science:

Volcanic rocks may record an unusually sudden magnetic field reversal.

Rocks may not talk, but they do tell tales. You just have to know how to read them.

A large rock formation near Battle Mountain, Nev., tells a dramatic story in the history of the Earth. You’d never guess if you saw the rocks because they look ordinary. But after studying minerals in those rocks, geologists report that 15 million years ago, the Earth’s magnetic field flipped: The north magnetic pole headed south, and it did so surprisingly quickly.

‘Batman’ Prepares To Join The Air Force

From the Danger Room:

Grappling hooks attached to siphon electricity from low-hanging power lines. Computers mounted onto a commando’s chest plate. Communications gadgets small enough to fit into gear pouches worn around the waist. The Air Force is actually preparing its special operators to act (and outfit themselves) more like the Batman.
