Researchers at the National Institute of Standards and Technology (NIST) have developed a method to measure the toughness"”the resistance to fracture"”of the thin insulating films that play a critical role in high-performance integrated circuits.
An electromagnetic phantom"”a carbon and polymer mixture that simulates the human body"”is being readied by the National Institute of Standards and Technology (NIST) for its upcoming role as a standardized performance test for walk-through metal detectors such as those used at airports.
Research conducted at the National Science Foundation (NSF) Nanoscale Science and Engineering Center for High-rate Nanomanufacturing (CHN) by the University of Massachusetts Lowell and Northeastern University led to the development of rapid template-assisted assembly of polymer blends in the nanoscale. The research team created a highly effective process that takes only 30 seconds to complete and does not require annealing.
Artificial bone marrow that can continuously make red and white blood cells has been created in a University of Michigan lab.
Electronic technologies could be deployed immediately and reliably to augment slower postal mail for distributing ballots to U.S. citizens living abroad, but using telephone, e-mail, and the Web to transmit completed ballots still faces significant, unresolved issues, according to a new report* released today.
Given the sheer number of potential applications for carbon nanotubes, experts in the field of nanotechnology are developing effective ways to mass produce intricate nanoscale structures for electronics, sensing, energy and biomedical applications in a timely, cost-effective manner with a high level of accuracy.
The more an animal walks during the day, the less energy it has to reproduce. Makes sense right? Not so fast, say two researchers at Washington University in St. Louis. They claim, based on a study of 161 mammalian species, that on average, animals which travel the longest distance each day to find food have the most offspring. The study, the first of its kind aimed at disproving the long-standing theory that more walking equates to less reproduction, was conducted by Herman Pontzer, Ph.D., assistant professor, and Jason Kamilar, Ph.D., research associate, both in anthropology in Arts & Sciences.
A University of Saskatchewan (U of S)-led research team at the Canadian Light Source (CLS) synchrotron has received an early Christmas present. After several years of research, construction and testing, the unique-in-North-America BioMedical Imaging and Therapy facility (BMIT) captured its first X-ray images.
Uzi Landman, professor of physics at the Georgia Institute of Technology, is the recipient of a Humboldt Research Award for Senior U.S. Scientists. He will accept the award in June 2009 at the annual meeting of the Alexander von Humboldt Foundation, to be held in Berlin.
James Holden, chief scientist of the latest voyage of the deep-sea research sub, Alvin, and colleagues describe microbes that thrive in 200-degree water and give off methane and hydrogen, in a paper this week. The mission was basic science but Holden sees possible use of byproducts as biofuels.
Researchers have developed a new generation of microscopic particles for molecular imaging, constituting one of the first promising nanoparticle platforms that may be readily adapted for tumor targeting and treatment in the clinic.
Researchers identify mechanisms behind biofilm formations, with implications for developing new antibiotics.
While modern spiders make silk threads with appendages called spinnerets, the primitive spider wove broad sheets of silk from spigots on plates attached to the underside of their bodies. Unlike spiders, they had long tails too. Even more creepy.
Findings reported by two University of Illinois at Chicago biologists have reaffirmed a recently disparaged "law" that says a species trait, once lost through evolution, can never be regained.
Raymond Habas, PhD, associate professor of biochemistry at UMDNJ-Robert Wood Johnson Medical School is one of this year's recipients of the Presidential Early Career Award for Scientists and Engineers (PECASE), the U.S. government's most prestigious award for exceptional young researchers. The award was announced by the National Institutes of Health and presented at a ceremony at the White House with President George W. Bush on Friday, December 19.
Here's one more reason to say "shade grown, please" when you order your morning cup of coffee. Shade coffee farms, which grow coffee under a canopy of multiple tree species, not only harbor native birds, bats and other beneficial creatures, but also maintain genetic diversity of native tree species and can act as focal points for tropical forest regeneration.
Scientists in the United Kingdom are reporting evidence that humans can make their own salicylic acid (SA) "” the material formed when aspirin breaks down in the body. SA, which is responsible for aspirin's renowned effects in relieving pain and inflammation, may be the first in a new class of bioregulators, according to a study scheduled for the Dec. 24 issue of ACS' biweekly Journal of Agricultural and Food Chemistry.
Using only the computing power of 16 Sony Playstation 3 gaming consoles, scientists at The University of Alabama in Huntsville and the University of Massachusetts, Dartmouth, have solved a mystery about the speed at which vibrating black holes stop vibrating.
Environmental research at colleges and universities isn't just scientific anymore. Increasingly, scientists are taking an approach to their work that includes more than laboratory analysis. That is the concept behind CLEAR, or Collaborative Education and Research, the brainchild of three professors at Middle Tennessee State University in Murfreesboro.
Modern humans left Africa over 60,000 years ago in a migration that many believe was responsible for nearly all of the human population that exist outside Africa today.
