Researchers at Virginia Tech are developing a more reliable and durable wood adhesive, polymeric isocyanate, to enhance the strength and stiffness of wood composites. The new adhesive reduces undesirable swelling caused by moisture and eliminates formaldehyde emissions.
University of Rhode Island researchers, Thomas Mather and David Nelson, are developing a new Lyme disease vaccine using tick saliva genes. They have received $2.3 million NIH grant to identify promising genes over five years.
Researchers found that exposure to agricultural fungicide Triphenyltin (TPT) can irreversibly suppress natural killer cell function, a crucial part of the human immune system. Even after TPT is removed, these cells are unable to regain their strength.
Freedman will develop general-purpose algorithms to track objects with varied properties using conventional cameras and MRIs. His work aims to improve surveillance and MRI technology, solving current problems such as object blocking and multi-property tracking.
Hydrogel nanoparticles provide a foundation for creating self-assembled periodic structures that can transmit specific wavelengths of light. By controlling the de-swelling process, the researchers can tune the colors to one-nanometer steps over a wavelength range of more than 200 nanometers.
Researchers at the University of South Florida found that individuals with the E4 type of apolipoprotein E (APOE) gene experience worse recovery of general memory function after brain injury. The study, which genotyped 110 head-injured patients, suggests common cellular responses in both traumatic brain injury and Alzheimer's disease.
A recent study by Dr. Lidija Siller from Newcastle University suggests that water might be trapped beneath the surface of Mars' south polar ice cap, a key factor in the formation of life on the planet. The research involves studying photochemical reactions in ice and has potential implications for the detection of life on Mars.
Researchers at Stanford University Medical Center have developed a novel approach to fighting cancer using a modified cold virus that targets cancer cells while leaving normal cells unharmed. In a phase I study, 28 patients who received the highest dose of the virus survived for nearly a year and saw significant tumor shrinkage.
Researchers at Thomas Jefferson University found that low doses of paclitaxel and docetaxel inhibit the growth of endothelial cells, leading to smaller tumors. The study suggests that oral versions of these drugs could be effective in treating cancer with chronic, low dose concentrations.
Rice chemists create polyfullerenes by joining C-60 molecules in polymer chains and planes, making them more stable than organic polymers. Fluorination of these polyfullerenes enables the creation of dozens of 'designer' nanotube derivatives with various side chains, making them soluble in traditional organic solvents.
The Ford Foundation grant will help researchers define problems facing social sciences, compare historical trajectories in several countries, and foster international discussion. Academically, the social sciences face challenges due to shifting emphasis on science, technology, and quantitative research methods.
Researchers have identified four chemicals that induce nerve regeneration in rat brain cells, focusing on the MAG-ganglioside interaction. The findings could lead to new treatments for spinal cord injury and multiple sclerosis, but caution is needed due to the complexity of human neural systems.
ChemGenex researchers used chemical genomics to identify molecular targets for Quinamed(TM) and predict anti-angiogenic properties for Ceflatonin(TM). These methods allowed the company to streamline drug discovery and validation, as well as identify potential side effects.
Researchers at Newcastle University are developing asynchronous systems that work well in labs and have potential for commercial use. These designs could overcome limitations imposed by traditional clocks on computer performance.
A new analysis tool developed by a University of Illinois researcher can help manufacturers determine the optimal price for combination vaccines. The tool considers various factors such as vaccine costs, individual and societal benefits, and consumer willingness to pay. By balancing these concerns, it aims to prevent overpayment by gov...
Researchers at Penn State Energy Institute have developed a new process for removing organic sulfur from hydrocarbon fuels using low-temperature and pressure methods. The SARS process selectively adsorbs sulfur on metal species without affecting aromatic compounds.
The grant will allow Rush to increase awareness among African-American men aged 50+, who are disproportionately affected by prostate cancer. The organization plans to conduct free screenings and refer patients to local doctors or Rush after diagnosis.
Dr. Larysa Pevny, a UNC neuroscientist, has received a $1 million federal grant to study the genetics of neural stem cells and their potential in developing transplantation therapy for neurodegenerative diseases.
