Chemical engineers at Purdue University have developed a computerized system that mimics evolution to discover new gasoline additives. The system combines and recombines chemical components until the fittest fuel additives emerge, offering improved engine performance by reducing deposits on engine valves.
A new UCSF study found that nearly all patients value primary care physicians for coordinating their care and serving as a first point of contact. However, nearly a quarter of patients feel their primary care physician or medical group limits access to specialists, leading to lower trust and satisfaction levels.
Researchers at Cornell University's Boyce Thompson Institute have developed a novel approach to genetically modifying plants by using chimeraplasty, a method that coats gold particles with short chimeric DNA/RNA molecules. This technique has the potential to improve crop yields and nutritional value without involving foreign DNA.
Researchers at the University of North Carolina at Chapel Hill have discovered that calcium channels help regulate cell movement by opening to admit more calcium ions when cells are stretched. This boost in motility enables cells to move forward again, which could lead to breakthroughs in wound healing and cancer treatment.
The University of Kentucky Markey Cancer Center will operate the Mid-South Cancer Information Service, providing up-to-date scientific information on cancer prevention and services. The five-year contract is worth $7.15 million.
A new study by University of Wisconsin-Madison psychologists found that males have only slightly higher levels of self-esteem than females across most ages. The analysis of nearly 150,000 respondents suggests that popular assumptions about a significant gender gap in self-esteem may be greatly exaggerated.
The catastrophic draining of two gigantic glacial lakes in Canada's Hudson Bay region led to the most abrupt, widespread cold spell on Earth during the last 10,000 years. Temperatures dropped by as much as 15 degrees Fahrenheit in central Greenland and by nearly 6 degrees F in Western Europe.
Scientists have successfully synthesized a new cubic phase of silicon nitride with exceptional hardness, outperforming stishovite, a high-pressure modification of SiO2. The novel material has the potential to replace diamond in certain technological applications where its extreme hardness is required.
A 5-year clinical trial led by Thomas Jefferson University aims to investigate the effects of GM1 ganglioside on improving Parkinson's disease symptoms, delaying disease progression, and restoring damaged brain cells. The study will compare the drug to standard treatments, using advanced imaging techniques to visualize dopamine termina...
Researchers at Vanderbilt University Medical Center are exploring the role of aspirin and similar drugs in preventing colon cancer. They will study the mechanism of COX2 inhibition and its potential as a therapeutic target for colon cancer prevention.
A new compound, BP 897, has been shown to reduce compulsive drug-seeking behavior in cocaine-dependent rats. This breakthrough could lead to a new treatment for addiction, targeting the root cause of craving and compulsive behavior.
A recent study led to misleading reports due to incorrect presentation of data, leading the researchers to urge for improved communication of research findings to the public. They suggest using absolute event rates, presenting risk ratios instead of odds ratios, and avoiding overgeneralization to provide realistic expectations.
The ONR report highlights the need for further research into the effects of underwater noise on marine life, including non-hearing physiological effects and behavioral changes. The report also reviews current scientific knowledge and expert opinions on the topic, emphasizing the importance of understanding the impacts of human activiti...
