In Galileo’s Footsteps

Galileo

From Newsweek:

For the first time in hundreds of years, the most powerful telescopes may soon come from Europe.
Galileo has been getting a lot of press lately, and no wonder. Four centuries ago this year, the Italian genius pointed his small, primitive telescope at the night sky and saw wonders nobody had imagined. His discoveries transformed our view of the heavens, but also infected astronomers with a permanent desire to peer just a bit deeper in the universe and find a few more cosmic secrets. Which is why, less than 20 years after they put the finishing touches on a generation of telescopes so big they would have made the Renaissance stargazer swoon, the astronomers are at it again. Three teams are racing to build telescopes four times wider and with up to 16 times the light gathering power than what exists now, and to have them trained on the stars by 2018.

Augmented Reality Reveals History to Tourists

From : Science News Service

Doing virtual reality one better, a consortium of technology companies and European Union countries have created a "visual time machine" that allows tourists equipped with a smart phone to take a picture of an ancient object and then instantly review its history and see what it originally looked like.

This new technology, dubbed the "Intelligent Tourism and Cultural Information through Ubiquitous Services" (iTacitus, after the Roman historian), brings augmented reality to museums, palaces, castles and other tourist attractions, according to its developers."[Tourists] can look at a historic site and, by taking a photo or viewing it through the camera on the mobile device, be able to access much more information about it," said Luke Speller, a scientist with the BMT engineering group based in the U.K. "They are even able to visualize, in real time, how it looked at different stages in history."

From Christian Science Monitor:

Today, winds help turn on the lights, run TVs and power washers, dryers and ovens in thousands of homes all over New England.

Silent surroundings almost tease the ears as clouds skitter across the top of this eastern corner of Maine. The wind, barely audible, swishes through beech and fir trees crowding the hills of an area so remote it’s part of the state’s Unorganized Territory.

Along the rounded ridge of Stetson Mountain, wisps of wind gain a whoosh-whoosh cadence as they push into motion mammoth blades at the tops of towers reaching hundreds of feet into the air.

Cosmos: Probably The Greatest Science Documentary In The Universe

Carl Sagan's Cosmos: A Personal Voyage provides a complete guide to life, the universe and everything.

From The Guardian:

Almost 30 years after it first aired, Carl Sagan's cosmic travel guide still educates, entertains and inspires awe.

I never got to watch Carl Sagan's epic science documentary Cosmos as a child. I was at boarding school in 1980 when it was released, so my TV watching was restricted. I've heard science journalist colleagues talk about the series almost with reverence, describing Sagan's commentary as "poetry". The 13 one-hour episodes of Cosmos: A Personal Voyage have just been re-released, digitally remastered and with updates on scientific progress in the quarter century that has passed since the series was created. Would it live up to such high expectations?

Send ET A Text Message From Earth

From Yahoo News/Space:

Here's a truly long-distance message...one aimed more than 20 light-years away.

A new Web site in Australia is gathering text messages from around the world, all to be beamed to a distant alien planet called Gliese 581d.

The clock is ticking to submit text messages of no longer than 160 characters – perhaps a signal that extraterrestrial life may have a case of attention deficit disorder. The project - called "Hello From Earth" - (http://www.HelloFromEarth.net) ends Aug. 24.

Once the communiques are amassed, they will be transmitted from NASA's Canberra Deep Space Communication Complex at Tidbinbilla.

From Time Magazine:

Even as a boy watching the first moon landing on TV, Brian Clegg remembers wondering, "How did it all begin?" In his latest book, Before the Big Bang, the Cambridge-educated writer examines the theories that physicists and philosophers alike have put forth to explain how we got here. TIME spoke with Clegg about science as a social network, thinking outside of the box without losing his mind, and using Buffy the Vampire Slayer to explain Einstein.

India Launches Bhuvan, Rival To Google Earth

From Times Online:

India has launched a rival to Google Earth, the search engine's hugely popular satellite imagery service.

The online tool, dubbed Bhuvan (Sanskrit for Earth), has been developed by the Indian Space Research Organisation (Isro). Its debut comes as India redoubles its efforts to reap profits from its 45-year-old state-sponsored space programme, criticised by some as a drain on a country where 700 million people live on $US2 a day or less.

The new site also follows in the slipstream of the country's first moon probe, Chandrayaan-1, which successfully reached the lunar surface last November.

Night-Time Photos Shed Light On Growing Economies

Bright lights, big GDP (Image: NOAA/SPL)

From New Scientist:

NIGHT-TIME images taken from kilometres above the Earth could help us better understand the economies of some of the planet's least developed countries. So say the US economists behind a method for measuring changes GDP using the intensity of street lights and other night-time lighting.

A better way of estimating GDP is badly needed, especially for poorer nations. Data collected by national governments is weak when it comes to informal sectors of the economy, such as street markets. In some countries, such as Liberia, economic information systems are so poor that meaningful data is sometimes non-existent.

Why Flamingoes Stand On One Leg

From The BBC:

It is one of the simplest, but most enigmatic mysteries of nature: just why do flamingoes like to stand on one leg?

The question is asked by zoo visitors and biologists alike, but while numerous theories abound, no-one has yet provided a definitive explanation.

Now after conducting an exhaustive study of captive Caribbean flamingoes, two scientists believe they finally have the answer.

Flamingoes stand on one leg to regulate their body temperature, they say.

Pollution Reduces Rain Vital To Crops

From Live Science:

Air pollution in China has cut the amount of light rainfall by 23 percent over the past 50 years, a new study finds.

The cause: Particles in air pollution cause smaller drops of water to form, and smaller drops have a harder time making rain clouds.

The result: Bad air could hamper the country's ability to grow food.

It is the first such study to link pollution to altered climate that can directly affect agriculture.

New Data: Mega-Quake Could Strike Near Seattle

Seattle Skyline

From McClatchy News:

WASHINGTON — Using sophisticated seismometers and GPS devices, scientists have been able to track minute movements along two massive tectonic plates colliding 25 miles or so underneath Washington state's Puget Sound basin. Their early findings suggest that a mega-earthquake could strike closer to the Seattle-Tacoma area, home to some 3.6 million people, than was thought earlier.

The deep tremors, which humans can't feel, occur routinely every 15 months or so and can continue for more than two weeks before they die back to undetectable levels.

Hubble's Deepest Look Into Space, Now Rendered In 3D

From Popular Science:

Over a period of four months in late 2003, the Hubble telescope assembled an image that represents the deepest look into space every composed. The Ultra Deep Field image captures an estimated 10,000 galaxies, some as old as 13 billion years (just a few hundred million years after the Big Bang, going by most estimates), all squeezed into a sliver of sky no bigger than what you'd see behind a 1-millimeter square postage stamp held one meter away.

Here's what it looks like in 3D.

Defense Last In WH Science Goals

From DoD Buzz:

The Obama administration’s budget guidance for 2011 makes clear that basic research spending will stay flat in most areas or decline, including at the Pentagon.

Money will first go to research that can “drive economic recovery, job creation, and economic growth,” says the guidance issued in an Aug. 4 memo by White House Office of Management and Budget Director Peter Orszag. The administration also makes clear that since they expect little new money for science and technology funding then government agencies must move dollars to what it calls four “practical challenges.”

My Comment: Many of our greatest technological and engineering accomplishments have come from the labs of Darpa and other defense related laboratories. So much for the campaign rhetoric that the sciences will benefit from an Obama administration. In fact .... it is the science that conforms to the political agenda of the White House that will now get the funding.

Robotic Systems Help People with Disabilities

With the help of a remote human assistant, a person with disability pilots a robotic mobility and manipulation system and opens a refrigerator door to retrieve a pre-prepared meal from home. Cooperative control leaves the person with disability in command, and the ability to use the capabilities of both the local pilot and remote human assistant enable safe, effective, and efficient operation of the robotic system in natural environments.

From Live Science:

People might be surprised to learn that about 50 million people in the world use, or could benefit from the use of, a wheelchair.

Wheelchairs are one of the most commonly used assistive devices for mobility, and they provide people with mobility within their homes and communities. While wheelchairs were once a symbol of inability and stigmatizing, they have evolved to be highly mobile forms of self-expression that are often fitted to each individual user.
