When stem cells are used to regenerate bone tissue, many wind up migrating away from the repair site, which disrupts the healing process. But a technique employed by a University of Rochester research team keeps the stem cells in place, resulting in faster and better tissue regeneration. The key, as explained in a paper published in Acta Biomaterialia, is encasing the stem cells in polymers that attract water and disappear when their work is done.

Experts analyzed samples from three sites located in the birthplace of Neolithic agricultural practices.

ANN ARBOR – With precarious particles called polaritons that straddle the worlds of light and matter, University of Michigan researchers have demonstrated a new, practical and potentially more efficient way to make a coherent laser-like beam.

They have made what's believed to be the first polariton laser that is fueled by electrical current as opposed to light, and also works at room temperature, rather than way below zero.

Imagine a technology that could allow us to see through opaque surfaces without exposure to harmful x-rays, that could give us the ability to detect harmful chemicals and bio-agents from a safe distance, and that could enable us to peer so deeply into space that scientists could better understand the formation of the universe.

YOUNG people from disadvantaged communities in Northern Ireland should be provided with "safe spaces" in which to protest and make their views known. This would help prevent them falling under the sway of extremists, argue researchers at the University of Huddersfield who played a major role in organising a conference in Belfast that investigated the "culture wars" of Ulster.

African-Americans such as Brown University President Ruth Simmons, Nobel Laureate Toni Morrison, and of course President Barack Obama have reached the pinnacle of success in historically white domains. But a new study finds there is a downside to African-American success stories: these positive examples prompt white Americans to think less successful African-Americans simply need to apply more effort to achieve their own success.

BONN, Germany (June 05, 2014) – Programs and policies to reduce tropical deforestation, and the global warming emissions resulting from deforestation, are seeing broad success in 17 countries across four continents, according to a new report from the Union of Concerned Scientists (UCS).

"You can create any shape, using any number of fingers, and in any size or location on the screen," Lindqvist said. "We saw that this security protection option was clearly missing in the scientific literature and also in practice, so we decided to test its potential."

CHAMPAIGN, Ill. — This growing season, crop researchers at the University of Illinois are experimenting with the use of drones – unmanned aerial vehicles – on the university's South Farms.

Dennis Bowman, a crop sciences educator with U. of I. Extension, is using two drones to take aerial pictures of crops growing in research plots on the farms. He presented his findings to farmers and other researchers at the 2014 Ford / Iroquois County Agronomy Day meeting.

Long-lost paintings have been discovered on the walls of Cambodia's ancient Angkor Wat temple, thanks to the keen observations of an Australian National University (ANU) researcher.

The ancient paintings date back almost 500 years and depict deities, animals, boats and the temple itself, giving historians a new understanding of life in a relatively unknown period of Cambodia's history.

Rock art researcher Noel Hidalgo Tan discovered the hidden images while working as a volunteer at an archaeological excavation in Angkor Wat during a university break in 2010.

Essential oils have boomed in popularity as more people seek out alternatives to replace their synthetic cleaning products, anti-mosquito sprays and medicines. Now scientists are tapping them as candidates to preserve food in a more consumer-friendly way. A study from ACS' Journal of Agricultural and Food Chemistry reports the development of new edible films containing oils from clove and oregano that preserve bread longer than commercial additives.

Cybercrime comes in all forms these days. One recent headline told of the creepware or silent computer snooping that resulted in the arrest of some 90 people in 19 countries. Miss Teen USA was among the victims. Her computer had been turned into a camera and used to spy on her in her own bedroom.

On the commercial front, Target suffered the largest retail hack in U.S. history during the Christmas shopping season of 2013, and now the Fortune 500 company's outlook is bleak with steep drops in profits.

Deep sea fishes remove and store more than one million tonnes of CO2 from UK and Irish surface waters every year, according to a new study led by the University of Southampton.

This natural carbon capture and storage scheme could store carbon equivalent to £10 million per year in carbon credits.

Fish living in deep waters on the continental slope around the UK play an important role carrying carbon from the surface to the seafloor.

Faster electronic device architectures are in the offing with the unveiling of the world's first fully two-dimensional field-effect transistor (FET) by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab). Unlike conventional FETs made from silicon, these 2D FETs suffer no performance drop-off under high voltages and provide high electron mobility, even when scaled to a monolayer in thickness.
