One-of-a-kind spectrometer reads vibrations between atoms to find structures of molecules A Rice University laboratory has improved upon its ability to determine molecular structures in three dimensions in ways that challenge long-used standards. By measuring the vibrations between atoms using femtosecond-long laser pulses, the Rice lab of chemist Junrong Zheng is able to discern the positions of atoms within molecules without the restrictions imposed by X-ray diffraction (XRD) and...

Biophysicists Zoom In On Pore-forming Toxin
2013-08-15 09:08:14

Rice University Study of melittin-based pore formation also applies to anticancer drugs A new study by Rice University biophysicists offers the most comprehensive picture yet of the molecular-level action of melittin, the principal toxin in bee venom. The research could aid in the development of new drugs that use a similar mechanism as melittin's to attack cancer and bacteria. The study appears this week in the Proceedings of the National Academy of Sciences. Melittin does its...

Embedded Diodes Boost Rice University Invention's Potential As Robust, Roomy Memory
2013-07-09 14:58:25

Rice University A Rice University laboratory pioneering memory devices that use cheap, plentiful silicon oxide to store data has pushed them a step further with chips that show the technology's practicality. The team led by Rice chemist James Tour has built a 1-kilobit rewritable silicon oxide device with diodes that eliminate data-corrupting crosstalk. A paper on the new work appears this week in the journal Advanced Materials. With gigabytes of flash memory becoming steadily...

New Material Created At Rice University With Graphene Oxide Flakes
2013-07-08 11:37:26

Rice University Large flakes of graphene oxide are the essential ingredient in a new recipe for robust carbon fiber created at Rice University. The fiber spun at Rice is unique for the strength of its knots. Most fibers are most likely to snap under tension at the knot, but Rice's fiber demonstrates what the researchers refer to as "100 percent knot efficiency," where the fiber is as likely to break anywhere along its length as at the knot. The new work from the Rice lab of chemist...

Drug-design Lessons Applied To Production Of Industrial Minerals
2013-06-18 08:46:22

Rice University Taking a page from computer-aided drug designers, Rice University researchers have developed a computational method that chemists can use to tailor the properties of zeolites, one of the world's most-used industrial minerals. The research is available online and will be featured on the June 21 cover of the Royal Society of Chemistry's Journal of Materials Chemistry A. The method allows chemists to work backward by first considering the type of zeolite they want to make...

Rice University lab combines graphene nanoribbons with tin oxide for improved anodes Researchers at Rice University have come up with a new way to boost the efficiency of the ubiquitous lithium ion (LI) battery by employing ribbons of graphene that start as carbon nanotubes. Proof-of-concept anodes – the part of the battery that stores lithium ions – built with graphene nanoribbons (GNRs) and tin oxide showed an initial capacity better than the theoretical capacity of tin...

Rice computational study tracks E. coli cells´ regulatory mechanisms Environment is not the only factor in shaping regulatory patterns – and it might not even be the primary factor, according to a new Rice University study that looks at how cells´ protein networks relate to a bacteria´s genome. The Rice lab of computer scientist Luay Nakhleh reported in the Proceedings of the National Academy of Sciences that when environmental factors are eliminated from an...

Method For Tailoring Optical Processors Unveiled
2013-05-21 14:34:15

Rice University Rice University scientists have unveiled a robust new method for arranging metal nanoparticles in geometric patterns that can act as optical processors that transform incoming light signals into output of a different color. The breakthrough by a team of theoretical and applied physicists and engineers at Rice's Laboratory for Nanophotonics (LANP) is described this week in the Proceedings of the National Academy of Sciences. Rice's team used the method to create an...

Combining Synthetic And Natural Toxins Could Disarm Cancer And Drug-resistant Bacteria
2013-02-12 08:22:35

Rice University Cancer researchers from Rice University suggest that a new man-made drug that's already proven effective at killing cancer and drug-resistant bacteria could best deliver its knockout blow when used in combination with drugs made from naturally occurring toxins. "One of the oldest tricks in fighting is the one-two punch -- you distract your opponent with one attack and deliver a knockout blow with another," said José Onuchic of Rice's Center for Theoretical...

How Blood Vessels Regroup After Stroke
2013-02-11 10:53:18

Rice University [ Watch The Video ] By thinking of cells as programmable robots, researchers at Rice University hope to someday direct how they grow into the tiny blood vessels that feed the brain and help people regain functions lost to stroke and disease. Rice bioengineer Amina Qutub and her colleagues simulate patterns of microvasculature cell growth and compare the results with real networks grown in their lab. Eventually, they want to develop the ability to control the way...

Word of the Day
  • A 'bachelor seal'; a young male seal which is prevented from mating by its herd's older males (mated bulls defending their territory).
This comes from the Russian word for 'bachelors.'
