Laser polishes components to a high-gloss finish

Millimeter by millimeter, the polisher uses grinding stones and polishing pastes to polish the surface of a metal mold, working at a rate of some ten minutes per square centimeter. This activity is time-consuming and hence incurs a significant cost. What is more, many companies are struggling to find new recruits for such a challenging yet monotonous task.

Hundreds of undiscovered artifacts found at Gallipoli

More than 100 artefacts from the First World War have been uncovered in an archaeological fieldwork survey on the Gallipoli battlefield, leading to some interesting theories about life on the frontline according to University of Melbourne survey archaeologist Professor Antonio Sagona.

The discoveries were made as part of a second season of fieldwork undertaken as part of the Joint Historical and Archaeological Survey – the only systematic survey of the battlefields of Gallipoli since the First World War.

Golf clubs help prove long-standing theory of cell stickiness

State-of-the-art, highly-sensitive golf clubs, developed by scientists, regularly catch the eye of golf's elite; however before the likes of Rory McIlroy get excited this time, this new golf putter is being put to use in microbiology laboratories.

The 'micro putter', developed for a study published in Measurement Science and Technology, has been designed to test the "stickiness" of single cells.

Does MRI pose more than minimal risk in pediatric research?

(Garrison, NY) Shedding light on a question that has baffled research ethics review boards, a new analysis of the use of magnetic resonance imaging (MRI) in pediatric clinical trials finds that the risks of physical and psychological harm associated with this procedure are no greater than the risks that healthy children face from everyday activities, such as playing soccer or riding in motor vehicles. However, adding an intravenous contrast dye or sedation to an MRI increases the odds of harm and makes them unacceptably high.

Certain biofuel mandates unlikely to be met by 2022; unless new technologies, policies developed

WASHINGTON — It is unlikely the United States will meet some specific biofuel mandates under the current Renewable Fuel Standard by 2022 unless innovative technologies are developed or policies change, says a new congressionally requested report from the National Research Council, which adds that the standard may be an ineffective policy for reducing global greenhouse gas emissions. Achieving this standard would likely increase federal budget outlays as well as have mixed economic and environmental effects.

Caltech engineers build smart petri dish

PASADENA, Calif. -- The cameras in our cell phones have dramatically changed the way we share the special moments in our lives, making photographs instantly available to friends and family. Now, the imaging sensor chips that form the heart of these built-in cameras are helping engineers at the California Institute of Technology (Caltech) transform the way cell cultures are imaged by serving as the platform for a "smart" petri dish.

Breakthrough: A robot brain implanted in a rodent

With new cutting-edge technology aimed at providing amputees with robotic limbs, a Tel Aviv University researcher has successfully implanted a robotic cerebellum into the skull of a rodent with brain damage, restoring its capacity for movement.

Oil shale energy without releasing carbon dioxide in a greenhouse world

WASHINGTON, Sept. 28, 2011 — New technology that combines production of electricity with capture of carbon dioxide could make billions of barrels of oil shale — now regarded as off-limits because of the huge amounts of carbon dioxide released in its production — available as an energy source, outlined in the Global Challenges/Chemistry Solutions podcast.

nQuire software brings science to life for young people

The use of new technology is helping students to become real 'science investigators'. Researchers funded by the Economic and Social Research Council (ESRC) and the Engineering and Physical Sciences Research Council (EPSRC) have developed a software toolkit that shows how such an approach sparks and sustains students' interest in science.

Toxic red tides: Tracking neurotoxin-producing algae

With toxic algal blooms — which can increase the amount of harmful toxins in the shellfish that California residents consume — ramping up in frequency and severity locally, scientists at USC have developed a new algae monitoring method in hopes of one day being able to predict when and where toxic "red tides" will occur.

"We have, what we fear, is a hotspot here for some types of toxic algal blooms," said David Caron, professor of biological sciences at the USC Dornsife College.

Carbon composite cars coming in 2013

The revolutionary material used to build the Boeing 787 Dreamliner, the Airbus A350 super-jumbo jet, and the military's stealth jet fighter planes is coming down to Earth in a new generation of energy-saving automobiles expected to hit the roads during the next few years. That ultra-strong carbon fiber composite material — 50% lighter than steel and 30% lighter than aluminum — is the topic of the cover story in Chemical & Engineering News,.

Adorable: Researchers think they can use Twitter to track world's mood swings

Using Twitter to monitor the attitudes of 2.4 million people in 84 countries, Cornell University researchers found that people all over the world awaken in a good mood – but globally that cheer soon deteriorates once the workday progresses. A commonly real magazine was happy to post this fad finding and pretend it is data.

By tracking Twitter tweets over two-years, sociologists determined that work, sleep and the amount of daylight all play a role in shaping cyclical emotions such as enthusiasm, delight, alertness, distress, fear and anger.

Early to bed and early to rise -- study suggests it's keeping kids leaner

DARIEN, IL – Ben Franklin was right, at least on the healthy part. "Early to bed and early to rise" appears to have helped a cross-section of early-bird Australian youths keep slimmer and more physically active than their night-owl peers, even though both groups got the same amount of sleep.

Women in science? Universities don't make the grade

Atlanta, GA—Despite years of trying to improve the number of women undergraduates in science and engineering, a new study shows most universities are failing. Not only are women lagging behind their male classmates, efforts to close the gap too often focus on students instead of faculty and institutional structures.

This is first study that looks at the full range of programs for undergraduate women in science and engineering in the U.S. It gathered information from nearly 50 difference programs.

National University of Singapore researchers have devised the world's first energy-storage membrane

A team from the National University of Singapore's Nanoscience and Nanotechnology Initiative (NUSNNI), led by principle investigator Dr Xie Xian Ning, has developed the world's first energy-storage membrane.
