Six new planets have been discovered orbiting nearby stars, bringing the total number of known planets outside our solar system to 28. The newly discovered planets are located within the habitable zones of their stars and have temperatures suitable for liquid water to exist in one case.
A Yale study reveals that postmenopausal women's ovaries are often removed during hysterectomy due to geographical location and surgeon experience, sparking concerns about informed consent. The research highlights significant variation in oophorectomy rates across different areas of the state and among surgeons with varying caseloads.
Dr. Julie R. Korenberg's comprehensive map integrates three ways of looking at the human genome, marking critical points with fluorescent signposts for rapid translation of clinical problems into genome-based solutions. The guide has significant practical applications in cancer treatment and genetic diagnosis.
Researchers at Yale University have successfully characterized the function of yeast genes, providing new insights into how human cells work. The study's findings could lead to better understanding and treatment of diseases like cancer.
The Ethel F. Donaghue Women's Health Investigator Program at Yale has awarded six faculty members grants to study novel approaches in women's health. Researchers will investigate gene therapy for ovarian cancer, dietary protein prevention of osteoporosis, and light therapy for depression during pregnancy.
A clinical trial using a robot to aid in therapy for stroke patients showed significant improvements in short- and long-term recovery of arm movement. The robot provides quantitative data on forces and movements, increasing the productivity of human therapists while maintaining its role as a complementary tool.
The UCSF AIDS Research Institute is hosting a symposium to discuss strategies for preventing the second HIV epidemic. Experts will cover topics such as vaccine development, drug resistance, and post-exposure prevention.
Researchers at Max-Planck-Gesellschaft have solved the three-dimensional structure of fumarate reductase dimer using X-ray crystallography. The enzyme plays a crucial role in anaerobic bacterial metabolism, and its structure reveals an electron transfer pathway from haem groups to FAD and then to fumarate reduction site.
A team of CU-Boulder researchers is conducting the largest field campaign ever to assess ozone concentrations and chemical changes in the Arctic stratosphere. They will use various instruments, including satellites, aircraft, balloons, and ground-based instruments, to study the effects of climate change on ozone depletion.
Researchers have developed a new method to explore autoimmune mechanisms in chronic Lyme disease, which could lead to better diagnosis and treatment. The technique identifies specific bits of the Lyme agent that trigger an immune response against the body's own cells.
Researchers created a transgenic rat model with human CETP to study atherosclerosis. The study showed that elevated CETP contributes to the development of atherosclerosis, supporting the use of an antibody-based vaccine to raise HDL cholesterol levels.
A University of Pittsburgh study has found that depressive symptoms are a significant risk factor for coronary heart disease among people with Type 1 diabetes. The study's results also suggest that blood sugar levels do not strongly predict the likelihood of this complication.
