Numerous electronic, optical and structural uses demonstrated; Advance reported in Aug. 19 issue of prestigious journal Science
University of Texas at Dallas (UTD) nanotechnologists and an Australian colleague have produced transparent carbon nanotube sheets that are stronger than the same-weight steel sheets and have demonstrated applicability for organic light-emitting displays, low-noise electronic sensors, artificial muscles, conducting appliqués and broad-band polarized light
Despite gains in the training of women scientists and the implementation of programs to help women overcome ingrained barriers, the career path of most women scientists at universities remains a difficult trek, fraught with roadblocks of bias, a sometimes chilly campus climate and the challenge of balancing family and work.
That, in short, is the conclusion of a group of prominent women scientists and administrators, including chancellors and provosts, in an analysis of the issue
Children who survive brain cancer struggle for years with the malevolent echo of the disease and its treatment, according to a new study from the Stanford University School of Medicine and Lucile Packard Children’s Hospital. Nearly one-third of former brain tumor patients require special education services, and many suffer from chronic headaches, nausea and seizures. Only about half of those old enough to drive do so.
Those who received radiation to cure their cancers fare
U-M-led study finds fear of recurrence and radiation treatment drives women – not their surgeons – to opt for mastectomy
When a woman is diagnosed with breast cancer, her top priority is to get the cancer out and reduce the odds that it will ever return. But for some women just getting the cancer out doesn’t feel like enough.
According to a new study led by researchers at the University of Michigan Comprehensive Cancer Center, when women, not their surgeons, have contro
Nur wenigen WM-Sponsoren gelingt es tatsächlich, einen hohen Bekanntheitsgrad im Umfeld des Sport-Ereignisses zu erreichen. Gleichzeitig bietet die Fußball-WM selbst Kleinunternehmen bestimmter Branchen die Chance, auch ohne Sponsoring-Engagement von dem Event zu profitieren. Speziell in der Tourismusbranche profitieren die WM-Städte vor allem von Tagesbesuchern, wenn auch in stark unterschiedlichem Maße. Zu diesem Ergebnis kommt die aktuelle Auswertung der Fußball-Langzeit-Studie von Prof. Dr.
New molecules help make stable catalysts that work at room temperature
Chemists at the University of California, Riverside have synthesized a new class of carbenes – molecules that have unusual carbon atoms – that is expected to have wide applications in the pharmaceutical industry, ultimately resulting in a reduction in the price of drugs.
Called cyclic alkyl amino carbenes or CAACs, the molecules attach themselves to metals, such as palladium, to form highly effici
The number of living Florida panthers has grown from a previously estimated 30 to a recently counted 87 as a result of a controversial breeding effort to improve the genetic health of the endangered and inbred animals, according to a new assessment.
Hybrid kittens born to panthers brought into the area from Texas have “about a three times higher chance of becoming adults as do purebred ones,” reports a paper planned for publication in January 2006 in the British journal Ani
Integrated European research project develops low-cost, modular and interactive automation solutions for SMEs
Automation makes you competitive ndustrial robots which, while being quick to install and easy to operate, are intended, thanks to their low-cost design, to make the competitive potential of automation technology available to European SMEs. “SMErobot” brings together leading European robot manufacturers, research institutes, scientists, software engineers and consultant
Recent Chandra observations have revealed new details about the fiery ring surrounding the stellar explosion that produced Supernova 1987A. The data give insight into the behavior of the doomed star in the years before it exploded, and indicate that the predicted spectacular brightening of the circumstellar ring has begun.
The supernova occurred in the Large Magellanic Cloud, a galaxy only 160,000 light years from Earth. The outburst was visible to the naked eye, and is the bright
Researchers at the University of California, Riverside have discovered that a simple worm, called C. elegans, makes an excellent experimental host for studying some of the most virulent viruses that infect humans.
The researchers published their findings in the Aug. 18 issue of the journal Nature in a paper titled, Animal virus replication and RNAi-mediated antiviral silencing in C. elegans.
UCR Professor of Plant Pathology Shou-Wei Ding co-authored the paper with Morr
Baby-boomers have spent more years living with more obesity than the previous generation, researchers at Beth Israel Deaconess Medical Center (BIDMC) have found. Although it may be too early to tell whether this will lead to a rise in arthritis rates, the study shows more obesity-related arthritis among baby boomers compared to the previous generation.
The study, published in the September issue of the American Journal of Public Health, concluded that obesity rates grew substantially fo
Researchers at UT Southwestern Medical Center have identified a biochemical switch that affects how neurons fire in a part of the brain associated with learning, findings that may aid in understanding schizophrenia and Alzheimer’s disease.
The research sheds new light on the action of reelin, a protein known to be important in the nervous system. During development, reelin sends cues to migrating neurons, telling them where they’re supposed to go. In adult mice, reelin h
Researchers studying zebrafish that die from anemia have discovered a new pathway for the synthesis of heme, the deep red, iron-containing molecule that is a component of hemoglobin and myoglobin. The research suggests that defects in this pathway may be an overlooked cause of anemia in humans.
A research team led by Leonard I. Zon, a Howard Hughes Medical Institute investigator at Children’s Hospital Boston and Harvard Medical School, published its findings in the August 18,
Data from the NASA/ESA/ASI Cassini spacecraft indicate that Saturn’s majestic ring system has its own atmosphere – separate from that of the planet itself.
During its close fly-bys of the ring system, instruments on Cassini have been able to determine that the environment around the rings is like an atmosphere, composed principally of molecular oxygen. This atmosphere is very similar to that of Jupiter’s moons Europa and Ganymede.
The finding was made by two
Opening the possibility of new therapies for type 2 diabetes, researchers at Washington University School of Medicine in St. Louis have found that a protein called Sirt1 enhances the secretion of insulin in mice and allows them to better control blood glucose levels. Their study will appear in the August 17 issue of Cell Metabolism.
According to senior author Shin-ichiro Imai, M.D., the finding suggests that therapies that increase the activity of Sirt1 could be of benefit in t
A paper published in the recent issue of Psychophysiology describes differences in the brain’s response (event-related potentials, or “ERPs”) to pictures and words that describe the same object. In two studies, the authors evaluated how the brain reacts differently to a picture of an object or its name when people were looking for either the picture or the name in a visual display.
University students saw pictures of five simple objects and words corresponding to their names.
