A colorful wheel developed by Rice University bioengineers to visualize protein interactions has won an international competition for novel strategies to study the roots of breast cancer.
Every year, October 4 is all about the protection of animals. On World Animal Day, animal welfare organisations around the globe advocate the respectful treatment and welfare of animals. One of the central demands of the animal activists is to abolish animal testing and to use alternative testing methods instead. In this context, the European Union has taken a huge step forward ...
The Pittcon Organizing Committee has announces the course listing for the 2014 Short Course program which runs March 1 through March 6, 2014. Short Courses are taught by industry experts; range from half-day up to two-day classes; and include beginner, intermediate, and advanced level curricula.
Pacemakers, insulin pumps, defibrillators and other implantable medical devices often have wireless capabilities that allow emergency workers to monitor patients. But these devices have a potential downside: They can be hacked. Researchers at Rice University have come up with a secure way to dramatically cut the risk that an implanted medical device (IMD) could be altered remotely without authorization.
Researchers at the Medical College of Wisconsin (MCW) have developed a new bioinformatics software tool designed to more easily identify genetic mutations responsible for cancers. The tool, called DrGaP, is the subject of a new paper published in the American Journal of Human Genetics.
In the process of metastasis, the movement of cancer cells to different parts of the body, a specific master regulator gene plays a central role: a transcription factor named Sox4 activates a sequence of genes and triggers the formidable process. Inhibition of Sox4 and subsequent processes may prevent metastasis in cancer patients.
Every cell of our body is separated from its environment by a lipid bilayer. In order to maintain their biological function and to transduce signals, special proteins, so called ion channels, are embedded in the membrane. Anna Stary-Weinzinger and Tobias Linder from the University of Vienna and Bert de Groot from the Max Planck Institute of Biophysical Chemistry in Göttingen identified a key...
When it officially came online at the San Diego Supercomputer Center (SDSC) in early January 2012, Gordon was instantly impressive. In one demonstration, it sustained more than 35 million input/output operations per second--then, a world record.
Donald Rowley, a pioneer in discovering how the immune system functions and the inventor of the gel electrode, a crucial tool that monitors cardiac activity, died at his home February 24, 2013,after a long battle with congestive heart failure. He was 90 years old.
The flip of a single molecular switch helps create the mature neuronal connections that allow the brain to bridge the gap between adolescent impressionability and adult stability. Now Yale School of Medicine researchers have reversed the process, recreating a youthful brain that facilitated both learning and healing in the adult mouse.
Dr. C. Everett Koop has long been regarded as the nation's doctor — even though it has been nearly a quarter-century since he was surgeon general. Koop, who died February 25, 2013, at his home in Hanover, NH, at age 96, was by far the best-known and most influential person to carry that title
Performing sensitive biological experiments is always a delicate affair. Few researchers, however, contend with the challenges faced by Cheryl Nickerson, whose working laboratory aboard the International Space Station (ISS) is located hundreds of miles above the Earth, traveling at some 17,000 miles per hour
What patterns exist in the evolutionary design of living things? What particular processes produced these patterns? And how might this information be used to untangle the complexities of health and disease, coded in human genes? These are among the central questions examined by Sudhir Kumar in his path-breaking research.
Vector NTI software is an integrated suite of sequence analysis and design tools that helps users manage, view, analyze, transform, share and publicize diverse types of molecular biology data, all within one graphically rich analysis environment
A new kind of pterosaur, a flying reptile from the time of the dinosaurs, has been identified by scientists from the University of Southampton, the Transylvanian Museum Society in Romania and the Museau Nacional in Rio de Janiero, Brazil
A team of researchers from Scotland has used a novel 3-D printing technique to arrange human embryonic stem cells (hESCs) for the very first time. It is hoped that this breakthrough will allow three-dimensional tissues and structures to be created using hESCs, which could, amongst other things, speed up and improve the process of drug testing
A cluster of tapeworm eggs discovered in 270-million-year-old fossilized shark feces suggests that intestinal parasites in vertebrates are much older than previously known, according to research published January 30, 2013, in the open access journal PLOS ONE by Paula Dentzien-Dias and colleagues from the Federal University of Rio Grande, Brazil.
A new study led by researchers at the University of California, Berkeley, represents a major advance in the understanding of the molecular mechanisms behind aging while providing new hope for the development of targeted treatments for age-related degenerative diseases
Vanderbilt University researchers have combined small-angle X-ray and neutron scattering with dynamic molecular modeling to determine how the structure of RPA responds as it engages DNA
It appeared Bono and arachnids didn't mix when his Spider-Man musical had a rough Broadway run, but that didn't keep a biologist from naming an actual spider species after the U2 singer
Day after day, legions of microorganisms work to produce energy from waste in biogas plants. Researchers are taking a close look to find out which microbes do the best job, analyzing the entire genetic information of the microbial communities in selected biogas plants
Because modern computers have to depict the real world with digital representations of numbers instead of physical analogues, to simulate the continuous passage of time they have to digitize time into small slices. The fact that it inevitably introduces errors is an ongoing problem for scientists. However, scientists have now identified and characterized the source of tenacious errors and come up with a way to separate the realistic aspects of a simulation from the artifacts of the computer method
For many years, scientists thought that mosquitoes provided the disease organisms that they spread with a relatively free ride, because the insects didn’t have much in the way of natural defenses to fight off these microscopic stowaways. Recent research, however, has revealed that mosquitoes have surprisingly sophisticated immune systems
Doctors have known for many years that patients with fragile X syndrome, the most common form of inherited intellectual disability, are often also diagnosed with autism. But little has been known about how the two diagnoses are related
