Professor uses diamond to produce graphene quantum dots and nano-ribbons of controlled structure

MANHATTAN, KAN. -- Kansas State University researchers have come closer to solving an old challenge of producing graphene quantum dots of controlled shape and size at large densities, which could revolutionize electronics and optoelectronics.

Vikas Berry, William H. Honstead professor of chemical engineering, has developed a novel process that uses a diamond knife to cleave graphite into graphite nanoblocks, which are precursors for graphene quantum dots. These nanoblocks are then exfoliated to produce ultrasmall sheets of carbon atoms of controlled shape and size.

Herschel Space Observatory study reveals galaxy-packed filament

A McGill-led research team using the Herschel Space Observatory has discovered a giant, galaxy-packed filament ablaze with billions of new stars. The filament connects two clusters of galaxies that, along with a third cluster, will smash together and give rise to one of the largest galaxy superclusters in the universe.

Could cap and trade for water solve problems facing the United States' largest rivers?

Lake Mead, on the Colorado River, is the largest reservoir in the United States, but users are consuming more water than flows down the river in an average year, which threatens the water supply for agriculture and households. To solve this imbalance scientists are proposing a Cap and Trade system of interstate water trading. The proposal, published in Journal of the American Water Resources Association (JAWRA), builds on the success of such an initiative in Australia.

Bluetooth baby

Checking the heart of the unborn baby usually involves a stethoscope. However, an inexpensive and accurate Bluetooth fetal heart rate monitoring system has now been developed by researchers in India for long-term home care. Details are reported in a forthcoming issue of the International Journal of Computers in Healthcare.

Research boom on ingredients for 'enhanced cosmetics'

Growing demand among baby boomers and others for "enhanced cosmetics" that marry cosmetics and active ingredients to smooth wrinkled skin and otherwise improve appearance is fostering research on micro-capsules and other technology to package those ingredients in creams, lotions and other products. That boom in research on encapsulation and other delivery technology is the topic of the cover story in the current edition of Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society (ACS), the world's largest scientific society.

3-telescope interferometry allows astrophysicists to observe how black holes are fueled

(Santa Barbara, Calif.) –– By combining the light of three powerful infrared telescopes, an international research team has observed the active accretion phase of a supermassive black hole in the center of a galaxy tens of millions of light years away, a method that has yielded an unprecedented amount of data for such observations. The resolution at which they were able to observe this highly luminescent active galactic nucleus (AGN) has given them direct confirmation of how mass accretes onto black holes in centers of galaxies.

Baby galaxies grew up quickly

Up until now, researchers thought that it had taken billions of years for stars to form and with that, galaxies with a high content of elements heavier than hydrogen and helium. But new research from the Niels Bohr Institute shows that this process went surprisingly quickly in some galaxies.

Astronomers discovered ancient Egyptian observations of a variable star

The study of the "Demon star", Algol, made by a research group of the University of Helsinki, Finland, has received both scientific and public attention. The period of the brightness variation of this eclipsing binary star has been connected to good prognoses three millennia ago. This result has raised a lot of discussion and the news has spread widely in the Internet.

Bright future for solar power in space

Solar power gathered in space could be set to provide the renewable energy of the future thanks to innovative research being carried out by engineers at the University of Strathclyde, Glasgow.

Researchers at the University have already tested equipment in space that would provide a platform for solar panels to collect the energy and allow it to be transferred back to earth through microwaves or lasers.

Geolocating soccer players

GPS isn't just for guiding confused drivers, it can also be used by soccer managers who are a little lost when it comes to assessing their players' performance. Acceleration, average and maximum speed, distance covered, etc. "It allows us to know the displacements of the players in a valid, reliable and effective way," says David Casamichana.

A deeper look at Centaurus A

Centaurus A, also known as NGC 5128 [1], is a peculiar massive elliptical galaxy with a supermassive black hole at its heart. It lies about 12 million light-years away in the southern constellation of Centaurus (The Centaur) and has the distinction of being the most prominent radio galaxy in the sky. Astronomers think that the bright nucleus, strong radio emission and jet features of Centaurus A are produced by a central black hole with a mass of about 100 million times that of the Sun.

To get the full flavor, you need the right temperature

Can the temperature of the food we eat affect the intensity of its taste? It depends on the taste, according to a new study by Dr. Gary Pickering and colleagues from Brock University in Canada. Their work shows that changes in the temperature of foods and drinks have an effect on the intensity of sour, bitter and astringent (e.g. cranberry juice) tastes but not sweetness. Their work is published online in Springer's Chemosensory Perception journal.

To avoid pain during an injection, look away

Philadelphia, PA, May 14, 2012 – Health professionals commonly say, "Don't look and it won't hurt" before administering an injection, but is there any scientific basis for the advice? A group of German investigators has found that, in fact, your past experience with needle pricks, along with information you receive before an injection, shape your pain experience. Their research is published in the May issue of Pain®.

Pay-to-play sports keeping lower-income kids out of the game

ANN ARBOR, Mich. – In an era of tight funding, school districts across the country are cutting their athletic budgets. Many schools are implementing athletic participation fees to cover the cost of school sports. But those fees have forced kids in lower-income families to the sidelines, according to a new poll that found nearly one in five lower-income parents report their children are participating less in school sports.

Real smart: Protective clothing with built-in A/C

Functional sportswear is taken for granted nowadays. It is quite unexceptional for a sports jacket, for instance, to be both waterproof and breathable. In the case of working clothes, the functionality is mostly restricted to personal protection against fire, sharp objects, chemicals and so on, with wearer comfort (mostly) not being significance top priority. Bullet-proof vests made of Kevlar, as their name suggests, hold off bullets but they are also impenetrable for water vapor. Thus police personnel who must wear such gear under their uniforms sweat profusely when the weather is warm.
