Pure carbon nanotubes pass first in vivo test

...t easier to see where the nanotubes end up, and it opens the door to some exciting diagnostic and therapeutic applications." In a ground-breaking 2002 study, Weisman and colleagues at Rice, including the late Professor Richard Smalley, discovered that nanotubes fluoresce, or emit near infrared light. Be...

Bacterial 'switch gene' regulates how oceans emit sulfur into atmosphere

...ugh in the microbial physiology of DMSP metabolism opens the door to understanding the biology and ecology of this globally important process," said William Whitman, a microbiologist at the University of Georgia and co-author of the Science paper. The discovery of a bacterial gene switch in these two group...

Analysis of breast-cancer gene role offers promising target

... HER-2 and urokinase given together." The study opens a promising avenue to increase the effectiveness of the drug trastuzumab (Herceptin) by adding a second drug seeking to neutralize the uPAR gene. "One major avenue of investigation would be to develop an antibody that prevents uPAR from binding to...

Worm links cancer risk to ageing

.... The fact that they appear to have dual functions opens a new way to study the connection between ageing and cancer." Scientists have long known that, statistically, ageing is a huge factor for cancer but have so far struggled to understand why that is. Professor Lithgow said: "If we look at checkpoint ...

Patients to benefit from novel technology revolutionizing high-speed molecular imaging

...quisition times, provides better image quality and opens the door to new diagnostic procedures using simultaneous multi-isotope imaging--providing the potential to revolutionize functional imaging, according to results released at SNM's 53rd Annual Meeting June 3? in San Diego. "The potential of using mo...

Origen publishes in Nature a robust and versatile method for creating transgenic chickens

...olyclonal antibodies. Moreover, the new technology opens up the possibility of producing chickens with enhanced agronomic traits, including resistance to avian flu. "This research breakthrough came when we turned our attention to primordial germ cells, the precursor cells to sperm and eggs," said Marie-Ce...

K-Staters design and build a low-cost remote sensing tool for environmental studies

...sing the sensing tool for nonmilitary applications opens up many possibilities for collecting reliable data in tricky or dangerous settings, such as studying dispersal of a smoke plume during a prairie fire; checking smokestack emissions; counting livestock in the pens at a feedlot; or checking crop fields...

Joslin discovers signs of residual islet cell function in people with long-term type 1 diabetes

...ications, reported Dr. Keenan. Overall, the study opens new avenues for research and treatment of type 1 diabetes. "The findings suggest that many patients, even after many years of diabetes, may still have some residual islet function. If a way can be found to stimulate islet growth, we could improve the...

Scientists tie several cancers to common 'oncogene engine'

...y suppress MITF, the identification of MITF's role opens a door to potential therapies because the researchers have identified some of the genes and proteins that MITF regulates that new drugs could be used to block. One of the targets is Bcl-2, which enables cancer cells to survive when the body has order...

Sperm created in the laboratory from embryonic stem cells produce viable progeny

...published in the July issue of Developmental Cell, opens many exciting avenues for future studies, including investigation of mechanisms involved in sperm production and development of new treatment strategies for infertility. Previous studies have shown that ES cells grown in the laboratory can different...

Finding paves way for better treatment of autoimmune disease

...bility to easily make large numbers of these cells opens the door to improved treatment and a better understanding of autoimmune diseases such as type 1 diabetes and arthritis, Medical College of Georgia researchers say. T cells are components of the immune system designed to attack invaders such as bact...

Flick of whiskers helps tease out brain's 'shadow' signaling system

... an organism during everyday circumstances. "This opens the door to whether these cells are part of everyday higher cognitive functioning that defines who we are as humans," she said. For years astrocytes have been related to the status of helper to the neurons, which rely on astrocytes to bring nutrient...
