Only in very few life phases do individuals face as many life transitions in such a short time as young adults at the age of 19-30. The transition from adolescence to adulthood is characterised by frequent changes in status or social roles, such as leaving the parental home, starting a career, entering into working life, forming a partnership and becoming a parent. Assuming civic and social responsibility is also an integral part of the lives of young adults at this particular life phase.

Researchers at the Georgia Tech Research Institute (GTRI) are developing a solid composite material to help cool small, powerful microelectronics used in defense systems. The material, composed of silver and diamond, promises an exceptional degree of thermal conductivity compared to materials currently used for this application.

LA JOLLA, Calif., March 1, 2011 – When patients receive a bone marrow transplant, they are getting a new population of hematopoietic stem cells. Fresh stem cells are needed when a patient is low on red blood cells, as in anemia, or white blood cells, which can be caused by cancer or even cancer treatments such as irradiation or chemotherapy. The problem is that a bone marrow transplant might not succeed because the transplanted stem cells don't live long enough or because they proliferate too well, leading to leukemia.

Computational scientists have a new weapon at their disposal.

On February 1, the Electronic Simulation Monitoring (eSiMon) Dashboard version 1.0 was released to the public, allowing scientists to monitor and analyze their simulations in real-time.

Using underwater speakers to play noise at levels similar to those produced by recreational speedboats, the researchers found that three-spined sticklebacks exposed to even brief noise playback made more foraging mistakes and were less efficient at consuming the available food compared to those in quiet conditions.

TEMPE, Ariz. – A team of researchers from Arizona State University, Stanford University and Carnegie Institution for Science has found that converting large swaths of land to bioenergy crops could have a wide range of effects on regional climate.

Troy, N.Y. – Benjamin Clough has developed a novel method for eavesdropping on terahertz information hidden in invisible plasma acoustic bursts. The doctoral student at Rensselaer Polytechnic Institute has demonstrated a promising technique that employs sound waves to boost the distance from which researchers can use powerful terahertz technology to remotely detect hidden explosives, chemicals, and other dangerous materials.

CHAMPAIGN, lll. — A farmer in Niger learns how to protect his crops from insects. A resident of Port-au-Prince or a rural Haitian village learns how to avoid exposure to cholera. An entrepreneur in Mali gets step-by-step instructions on extracting the oil from shea seeds to make shea butter she can sell at a local market.

The bones of people who died up to a hundred years ago are being used in the development of new treatments for chronic back pain. It is the first time old bones have been used in this way.

The research is bringing together the unusual combination of latest computer modelling techniques developed at the University of Leeds, and archaeology and anthropology expertise at the University of Bristol.

Students' social skills and behaviour in social situations during their university studies contribute to their success in the transition to work. The social strategies adopted during university studies also have an impact on work commitment and early-career coping with working life. These results have been uncovered in a research project investigating the relationship between the social strategies students show at university and how well they cope with work-related challenges. The research has been carried out with funding from the Academy of Finland.

Researchers at North Carolina State University have developed a cheap and easy method for assembling nanowires, controlling their alignment and density. The researchers hope the findings will foster additional research into a range of device applications using nanowires, from nanoelectronics to nanosensors, especially on unconventional substrates such as rubber, plastic and paper.

Indonesia has promised to become a world leader in reducing greenhouse gas emissions. In 2009, the president committed to a 26% reduction in greenhouse gas emissions by 2020 to below 'business-as-usual' levels. Of this total, 14% would have to come from reducing emissions from deforestation or forest degradation. Investments by foreign governments and other bodies are expected to raise total emission reduction from 26% to 41%.

BOSTON, Feb. 28, 2011 – In the first study to make head-to-head comparisons between tenofovir gel and oral tenofovir – two promising approaches for preventing HIV in women – researchers found that daily use of the vaginal gel achieved a more than 100-times higher concentration of active drug in vaginal tissue than did the oral tablet, while, compared to the gel, the tablet used daily was associated with a 20-times higher active drug concentration in blood.
