Educational game designers from Rice University's Center for Technology in Teaching and Learning (CTTL) are preparing to create their first online game series about clinical trials. The new series, called "Virtual Clinical Trials," will be the sixth in CTTL's popular Web Adventures series for young teens.
Recent research suggests that losing the ability to make a particular kind of sugar molecule boosted disease protection in early hominids, and may have directed the evolutionary emergence of our ancestors, the genus Homo .
Lawrence Livermore National Laboratory, working with Loyola University, has won a $3.5 million grant from the National Institutes of Health to help develop a new anthrax vaccine. The grant is the first major NIH-funded biodefense grant focused on LLNL's nanolipoprotein technology.
Using short snippets of RNA to turn off a specific gene in certain immune cells, scientists have shown that they can shut off the inflammation responsible for diseases such as atherosclerosis. This technique, known as RNA interference, offers a targeted way to stop inflammation and could be useful in treating not only atherosclerosis, but also other forms of heart disease as well as cancer.
A slight change in molecular structure introduced by genetic engineering gives crop-protecting proteins called Bt toxins a new edge in overcoming resistance of certain pests, a University of Arizona-led team of researchers reports.
Scientists at the University of Notre Dame have developed a special molecule that can out-compete allergens that attempt to attach to the type of white blood cell that is the source of allergic reactions.
New research from Northwestern University offers strong evidence that the brain uses predictive coding to generate “predictive templates” of specific smells—setting up a mental expectation of a scent before it hits your nostrils.
Plants may have the genetic flexibility to respond to climate change. In experiments with the common European plant Arabidopsis thaliana , a team of researchers led by Brown University scientists learned that climate is the agent that determines the suite of genes that gives the plant the best chance of surviving and reproducing throughout its natural range.
Data from a clinical trial involving University of California, Los Angeles researchers suggest that a new therapy may potentially serve as a "functional cure" for HIV/AIDS. The therapy, called SB-728-T, involves the modification of both copies of a patient's CCR5 gene, which encodes the major co-receptor used by HIV to infect immune system cells.
An University of Illinois research team has succeeded in overcoming one major obstacle to a promising technology that simultaneously reduces atmospheric carbon dioxide and produces fuel.
Purdue University is part of a national institute that received a grant of up to $35 million over the next five years from the U.S. Food and Drug Administration (FDA). The FDA awarded the grant to the National Institute for Pharmaceutical Technology and Education, or NIPTE, to improve manufacturing standards and ultimately cut health care costs, create jobs, and improve drug safety.
Researchers at Lawrence Livermore National Laboratory recently received $3 million from the National Institutes of Health to acquire a new biomedical accelerator mass spectrometry (bioAMS) instrument. The instrument will provide faster analysis for medical and other biological research.
Scientists call it LUCA, the Last Universal Common Ancestor, but they don't know much about this great grandparent of all living things. Many believe LUCA was little more than a crude assemblage of molecular parts, a chemical soup out of which evolution gradually constructed more complex forms. Some scientists still debate whether it was even a cell. However, new evidence suggests LUCA was a sophisticated organism after all.
Detailed in a paper published Wednesday, U.S. scientists have used a cloning technique to create the type of customized stem cells that show promise for treating disease. But the first-of-its-kind result comes with a big hitch: too much genetic material inhibits its function.
A putter made by scientists would normally be of interest to professional golfers, but not the one recently created in Japan. With a length of 240 ?m, a width of 30 ?m and a tip of just 2 ?m, golfers would not even be able to see the miniature club, which will be used to putt yeast cells rather than golf balls.
Picture this: You've brought your sick child to the doctor's office. After checking her pulse and blood pressure, he takes a nasal or throat swab and inserts it into a mysterious black box. Before the doctor finishes his examination, the black box beeps, indicating that the pathogen that's making your child sick has been identified. This scenario is now closer to becoming a reality.
Green tea may slow down weight gain and serve as another tool in the fight against obesity, according to Penn State University food scientists. In an animal study, obese mice that were fed a compound found in green tea along with a high-fat diet gained weight significantly more slowly than a control group of mice that did not receive the green tea supplement.
When a small bug landed on Dr. Igor Siwanowicz's hand and began "fiercely digging its mandibles" into his skin, he didn't swat it away. Instead, he captured and began taking photomicrographs. To his surprise, the image took first place in the 2011 Nikon Small World competition.
The Deepwater Horizon spill contained a large amount of natural gas, which immediately became food for bacteria. In a new study, scientists explain how they used DNA to identify the microbes present in the Gulf of Mexico during the spill, and how temperature played a role the microbes' ability to consume the gas.
Two heat-loving fungi, often found in composts that self-ignite without flame or spark, could soon have new vocations. The complete genetic makeup of Myceliophthora thermophila and Thielavia terrestris has been decoded by an international group of scientists. The findings may lead to the faster and greener development of biomass-based fuels, chemicals, and other industrial materials.
With new cutting-edge technology aimed at providing amputees with robotic limbs, a Tel Aviv University researcher has successfully implanted a robotic cerebellum into the skull of a rodent with brain damage, restoring its capacity for movement.
At the end of the last Ice Age, atmospheric carbon dioxide levels rose rapidly as the planet warmed; scientists have long hypothesized that the source was carbon dioxide released from the deep ocean. But a new study using detailed radiocarbon dating of foraminifera found in a sediment core from the Gorda Ridge off Oregon reveals that the Northeast Pacific was not an important reservoir of carbon during glacial times.
The Alexandrium catenella algae produces saxitoxin, one of the most toxic biologically produced chemicals in the world. In California, this toxin is increasingly finding its way into shellfish. A new type of quantitative assay has been developed to keep track of the algae.
Molecular motion in proteins comes in three distinct classes, according to a collaboration by researchers at Oak Ridge National Laboratory and the University of Tennessee. The research team combined high-performance computer simulation with neutron scattering experiments to understand atomic-level motions that underpin the operations of proteins.
Researchers at Rutgers University and UMDNJ-Robert Wood Johnson Medical School have determined the structure of a protein that is the first line of defense in fighting viral infections including influenza, hepatitis C, West Nile, rabies, and measles.
