Did the early universe have one dimension?

April 21, 2011 5:25 am | News | Comments

Did the early universe have just one spatial dimension? That's the mind-boggling concept at the heart of a theory that Univ. at Buffalo physicist Dejan Stojkovic and colleagues proposed in 2010. Now, in a new paper in Physical Review Letters , Stojkovic and Loyola Marymount Univ. physicist Jonas Mureika describes a test that could prove or disprove the "vanishing dimensions" hypothesis.

Researchers find fat turns into soap in sewers

April 21, 2011 5:13 am | News | Comments

Researchers from North Carolina State Univ. have discovered how fat, oil and grease (FOG) can create hardened deposits in sewer lines: it turns into soap. The hardened deposits, which can look like stalactites, contribute to sewer overflows.


New tool for metabolic engineering and synthetic biology

April 21, 2011 5:03 am | News | Comments

JBEI and Berkeley Lab researchers have demonstrated a new technique for the metabolic engineering of microbes that speeds up and improves the identification and quantification of proteins within a cell or organism. The new technique is called "targeted proteomics."

Research team creates protein-patterned fibers

April 21, 2011 4:39 am | News | Comments

Researchers at Rice Univ. and Texas A&M have discovered a way to pattern active proteins into bio-friendly fibers. The "eureka" moment came about because somebody forgot to clean up the lab one night.

Solution for water scarcity: Fog harvesting?

April 21, 2011 4:27 am | by Peter Dizikes, MIT News Office | News | Comments

An MIT graduate student is working to make water available for the world’s poor by refining the tools and techniques of fog harvesting.

Seeing the light

Optogenetic technology restores visual behavior in mice, holds promise for treating human blindness.

LED efficiency puzzle solved

April 20, 2011 6:02 am | News | Comments

Researchers at the Univ. of California, Santa Barbara, say they've figured out the cause of a problem that's made light-emitting diodes (LEDs) impractical for general lighting purposes. Their work will help engineers develop a new generation of high-performance, energy-efficient lighting that could replace incandescent and fluorescent bulbs.


Researchers are one step closer to controlled engineering of nanocatalysts

April 20, 2011 5:54 am | News | Comments

A research team from the UCLA Henry Samueli School of Engineering and Applied Science has proposed and demonstrated a new approach to producing nanocrystals with predictable shapes by utilizing surfactants, biomolecules that can bind selectively to certain facets of the crystals' exposed surfaces.

Biosensor microchip could speed up drug development

April 20, 2011 5:45 am | News | Comments

Stanford researchers have developed a new biosensor microchip that could significantly speed up the process of drug development. The microchips, packed with highly sensitive "nanosensors," analyze how proteins bind to one another, a critical step for evaluating the effectiveness and possible side effects of a potential medication.

Study finds way to measure brand personality appeal

April 20, 2011 5:27 am | News | Comments

Companies spend millions to develop their brand's personality, in hopes that it can help sell products. But they've had no way of measuring whether that personality actually appeals to consumers. Now, research from North Carolina State Univ. lays out a system for measuring the appeal of a brand’s personality.

Nature sets standard for nanoscience revolution

April 19, 2011 5:12 am | News | Comments

By striving for control and perfection in everything from computer chips to commercial jets, scientists and engineers actually exclude a fundamental force that allows nature to outperform even their best efforts. Although it may appear to defy logic, imperfections, and the seemingly randomness among even the lowly bacteria help keep nature a couple of steps ahead, according to Oak Ridge National Laboratory researchers.

Berkeley Lab scientists discover dynamic double-strand break repair in heterochromatin

April 19, 2011 5:01 am | News | Comments

Once called "junk DNA" because it contains numerous repeated short sequences that don't code for proteins, heterochromatin is in fact vital for normal growth and function. Yet it poses special challenges to accurate DNA repair. Berkeley Lab life scientists have discovered an unsuspected and dramatic process by which double-strand breaks in heterochromatin are repaired in dynamic stages.

Hole poked in century-old astronomical theory

April 19, 2011 4:31 am | News | Comments

This month, thousands of middle-school students are going online to play an interactive video game. That might not sound surprising, by itself. But in this case, the game is a special science-mystery project, "Vanished," created by MIT researchers on behalf of the Smithsonian Institution, as a novel experiment in alternative science education.

Berkeley Lab researchers find plasmonic resonances in semiconductor nanocrystals

April 18, 2011 7:39 am | News | Comments

Berkeley Lab researchers have achieved plasmonic properties in the semiconductor nanocrystals known as quantum dots. Until now plasmonic properties have been limited to nanostructures that feature interfaces between noble metals and dielectrics. This new discovery should make the already hot field of plasmonic technology even hotter.
