A list of recent Nobel Prize in chemistry winnersOctober 6th, 2009 List of recent Nobel Prize in chemistry winnersRecent winners of the Nobel Prize in chemistry, and their research, according to the Nobel Foundation:
— 2009: Americans Venkatraman Ramakrishnan and Thomas A. Steitz and Israel's Ada E.
Catalyst simulations for fuel cells may make clean cars a realitySeptember 18th, 2009 WASHINGTON - University of Wisconsin-Madison researchers are working towards developing better catalyst for fuel cells in a bid to make clean cars a reality. If successful, the researchers could make a car that runs on hydrogen from solar power, and produces water instead of carbon emissions.
Cell isolated from bio-clock can still keep timeSeptember 10th, 2009 WASHINGTON - Alexis Webb enters a small room painted dark green, turns off the lights and bends over a microscope over a black box to see a single nerve cell on a glass cover slip glowing dimly - indicating the isolated cell is busy keeping time. Researchers at Washington University in St.
Now, acoustic tweezers to position tiny objectsAugust 29th, 2009 WASHINGTON - While it gets quite difficult to manipulate tiny objects like single cells or nanosized beads via relatively large, unwieldy equipment, Penn State engineers have now designed a new system that uses sound as a pair of tiny tweezers that are small enough to place infinitesimal objects on a chip. While optical tweezers are large and expensive, acoustic tweezers are smaller than a dime, small enough to fabricate on a chip using standard chip manufacturing techniques.
Breakthrough opens way to developing tiny bio-fuel cellsJuly 1st, 2009 WASHINGTON - A breakthrough in making miniscule brushes potentially opens the way to bio-fuel cells that can power pace-makers, cochlear implants and prosthetic limbs. University of Georgia (UGA) chemist Jason Locklin and graduate students Nicholas Marshall and Kyle Sontag grew polymer brushes, made up of chains of aromatic molecules sometimes used as solvents, attached to metal surfaces as ultra-thin films.
"Glow or no glow" technique maybe used to defend against biological terror attackJune 18th, 2009 WASHINGTON - A new evaluation of a "glow or no glow" technique may soon help the US Department of Homeland Security (DHS) defend the nation against a spectrum of biological weapons that could be used in a terrorist attack. The National Institute of Standards and Technology (NIST) have done the evaluation.
Lasers can make cheaper, better solar cellsMay 30th, 2009 LONDON - Using lasers to make solar photovoltaic cells that produce electricity from sunshine makes these cells cheaper and better, researchers say. Arnold Gillner, microtechnology head at the Fraunhofer Institute for Laser Technology in Germany, said: "Lasers work quickly, precisely, and without contact.
Scientists power artificial cells with non-stop mobilityMay 5th, 2009 WASHINGTON - Scientists are developing artificial cells with the ability to tap an energy source and use it for sustained mobility. A Japanese study described the first 'self-propelled' oil droplets (used as a model for research on artificial cells) that can run on a chemical 'fuel'.
Now, nanoneedle to help examine biological processes of living cellsApril 29th, 2009 WASHINGTON - Researchers from University of Illinois have developed a nanoneedle that will help in examining biological processes occurring within living cells. "Nanoneedle-based delivery is a powerful new tool for studying biological processes and biophysical properties at the molecular level inside living cells," said Min-Feng Yu, a professor of mechanical science and engineering and corresponding author.
Revolutionary nano-needle can peer into a cellApril 29th, 2009 WASHINGTON - A revolutionary nano-needle, developed by researchers, not only peers into individual cells, but also acts as electro-chemical probe and optical biosensor. 'Nano-needle-based delivery is a powerful new tool for studying biological processes and biophysical properties at the molecular level inside living cells,' said Min-Feng Yu, professor of mechanical science and study coauthor, University of Illinois (U of I).
Microbes can produce abundant source of methane as fuelMarch 31st, 2009 WASHINGTON - A tiny microbe that converts carbon dioxide and water to methane with a bit of solar or wind power, can be a new energy source, according to a team of Penn State engineers. Methane is preferred over hydrogen because a large portion of the US infrastructure is already set up to easily transport and deliver methane.
Pentagon planning to regrow human limbsMarch 27th, 2009 WASHINGTON - Scientists at the Pentagon have completed the first phase of their plan to regrow soldiers' limbs, by turning human skin into the equivalent of a blastema - a mass of undifferentiated cells that can develop into new body parts. Now, researchers are on to phase two: turning that cellular glop into a square inch of honest-to-goodness muscle tissue.
New RNA treatment can shrink cancersMarch 20th, 2009 WASHINGTON - A newly-identified type of microRNA could tackle aggressive cancers by helping to kill off their cells. 'MicroRNAs are very small, newly-identified RNA elements of the cell, and we've shown that one in particular - microRNA-7 or miR-7, can play a profound role in reversing cancer cell growth,' said Peter Leedman, a professor who led the research team.
Platinum nanowires may pave way for more efficient fuel cellsMarch 12th, 2009 WASHINGTON - Researchers at the University of Rochester have created long platinum nanowires that may lead to the development of commercially viable fuel cells. It is believed that the new wires could provide significant increases in both the longevity and efficiency of fuel cells, which have until now been used largely for such exotic purposes as powering spacecraft.
New imaging tool helps scientists 'see' cell molecules more clearlyJanuary 19th, 2009 WASHINGTON - A powerful new tool can image single molecules in a cell, with much greater clarity and speed, compared to existing methods. The new tool, dubbed liquid scanning transmission electron microscope or liquid STEM, uses a micro-fluidic device with electron transparent windows to enable the imaging of cells in liquid.
