A research team at the Salk Institute has successfully regenerated a wing in a chick embryo by activating Wnt signaling, a powerful system controlling vertebrate regeneration. The study opens up new areas of research into the ability of stem cells to build new human body tissues and parts.
A $525,000 NSF CAREER grant will help faculty and graduate students develop skills for interdisciplinary research, a growing necessity in complex technological challenges. The project will survey 1,000 faculty and 1,250 students across 20 disciplines to develop assessment tools and strategies.
A weeklong intervention in schools reduced adolescents' inclination to drink by teaching them critical thinking skills and strategies to question alcohol ads. The program, led by Penn State's Marvin E. Goldberg, equipped students with persuasion knowledge and processed advertising messages.
Researchers have found that the experimental drug ABT-737 can destroy AML blast, progenitor and stem cells, potentially providing a new way to treat cancer. Combining ABT-737 with another agent may overcome resistance and improve treatment outcomes.
Morgan argues that legislators should impose regulations to prevent the construction of long-lived conventional coal plants. The US electricity industry plans to build 154 new plants in the next 24 years, with 50 slated for construction within five years.
The authors argue that with collective pension and health insurance programs in place, individuals can avert poor health, finances, and employer age discrimination. Aging Nation offers a new aging policy framework based on the interconnectedness of lives across generations.
A new research tool developed by Susan Liebman may provide a means for treating the earliest stage of Alzheimer's disease. The yeast model system detects A-beta small aggregate formation, allowing for high-throughput screening of compounds to inhibit aggregation.
A UGA professor studied the origins of Calories, a unit measuring food energy. He found that there is controversy about who invented the Calorie, with different sources citing Frenchmen P.A. Favre and J.T. Silbermann, German physician Julius Mayer, and French chemist Nicholas Clement as contributors to its development.
A retrospective study of 33,000 women with osteoporosis found that Actonel significantly reduced the risk of hip fractures compared to alendronate. The results showed a 46% lower incidence of hip fractures at six months and a 43% reduction at 12 months.
Scientists from the University of Miami's Rosenstiel School have developed an approach to investigate ocean reefs, which are considered the core of most living organisms. The new study has shed light on how stromatolites form and offers a new way to explore the origins of these living records.
Long-term Fosrenol treatment improves bone formation and reduces phosphorus levels in CKD stage 5 patients, according to a two-year study. The reformulated tablets also demonstrate efficacy as monotherapy for controlling serum phosphorus levels.
Michael Hernandez, a junior at University of Miami, won Outstanding Student Poster in geosciences category at SACNAS national conference. His research compared CHAMP radio occultations with global model forecasts during the 2005 hurricane season.
A study published in Nature demonstrated TB4's ability to regenerate coronary vessels in mice, a finding that could lead to new treatments for human heart disease. TB4 may prevent loss of heart muscle cells and restore blood flow, providing a much-needed treatment modality.
Researchers propose that natural selection drives the evolution of cancer, with tumor cells constantly evolving through mutation and selection. This understanding could lead to new therapeutic strategies, such as targeting benign cells to outcompete malignant ones.
A multicenter pilot study found that structured physical activity improved physical functioning in sedentary elderly individuals. Participants who exercised regularly showed significant improvements in walking distance and reduced risk of major mobility disability.
Researchers found that diastolic heart failure patients have severely reduced exercise tolerance despite normal leg blood flow, suggesting other factors such as muscle oxygen use contribute to symptoms. The study suggests targeting these additional factors could help develop effective treatments for this common form of heart failure.
Researchers at Brookhaven National Laboratory have characterized a component of the SARS virus that will be the target of new anti-SARS drugs. By determining the concentration at which individual proteinase molecules form active dimers, scientists can search for compounds that bind to the active form of the enzyme.
Dr. Liana Talaue-McManus and Dr. John W. McManus, researchers at the University of Miami Rosenstiel School, were named Associates of the World Technology Network for their innovative work in marine science and technology.
Scientists discover that the structure of the bases, rather than the backbone, is critical in developing genetic material. They created molecules with alternative bases and found that only one pair was strong enough to form specific base pairs.
The Woodruff Foundation is contributing $261.5 million to support Emory University's modernization of outpatient care facilities and strategic priorities. The gift includes funds for a new Emory Clinic complex, renovation of administrative buildings, and investment in initiatives related to the university's vision.
Researchers at UCI found that cholinergic neuronal circuits rely on neurotrophin-3 to recognize and reach target nerve cells in the brain. This discovery may lead to potential treatments for Alzheimer's disease by inducing nerve fibers to regrow in the cerebral cortex.
A team of researchers, led by Lehigh University's Volkmar Dierolf, has received a $1.2-million grant to study the nanostructure of ferroelectric domains. They aim to image and control these domains at the nanoscale to engineer devices.
A new UCLA study found that pediatric patients undergoing tonsillectomies can be safely discharged after a short post-operative recovery period at an outpatient surgery center. The study, which reviewed nearly 800 patient records, showed no increased complications with average discharge times of 1 hour and 47 minutes.
A Mayo Clinic review found that gene expression profiling has limitations in predicting lung cancer prognosis, with conventional methods remaining more accurate. Despite promising results, the technology's accuracy varies greatly among studies, and its clinical relevance is unclear.
Rice University chemists have successfully created and grown carbon nanotube seeds, which can be used to produce large quantities of pure nanotubes. The breakthrough offers significant potential for various materials applications, including energy storage and electronics.
Two studies by Rhode Island Hospital confirm the safety and efficacy of drug-eluting stents in patients with heart disease. The studies found that DES are as safe as bare metal stents, with lower rates of repeat procedures and mortality rates comparable to BMS.
