This image by the Hubble Space Telescope shows a dramatic view of the spiral galaxy M51, dubbed the Whirlpool Galaxy.
Preliminary research suggests that use of a type of molecular imaging procedure may have the ability to detect the presence of beta-amyloid in the brains of individuals during life, a biomarker that is identified during autopsy to confirm a diagnosis of Alzheimer disease, according to a study in the January 19 issue of JAMA.
A new analysis of the Northern Hemisphere's "albedo feedback" over a 30-year period concludes that the region's loss of reflectivity due to snow and sea ice decline is more than double what state-of-the-art climate models estimate.
Older adults without dementia and with lower levels in plasma of the biomarkers beta-amyloid 42/40 (protein fragments) had an increased rate of cognitive decline over a period of 9 years, according to a study in the January 19 issue of JAMA. The researchers also found that this relationship was stronger among individuals with less education and lower levels of literacy.
Personal health records have great potential to help patients manage their health, but technology needs to be designed with the patient in mind which means doing more than helping patients access health information, according to an editorial by two Virginia Commonwealth University family medicine physicians published in the Jan.19 issue of the Journal of the American Medical Association.
Not many college students can say their efforts in the laboratory may lead to therapies for diseases that devastate millions of people worldwide, but chemistry students in the School of Science at Indiana University-Purdue University Indianapolis can. As they learn the science of chemistry they are actually synthesizing molecules that may someday be tested in human clinical trials as potential...
Nissan Motor had delivered only 60 units of its Leaf electric vehicle in Japan as of Friday, Kyodo News reported, despite already taking 6,000 orders due by the end of March.
Using chemical compounds found in a Japanese plant as a lead and the clever application of ultraviolet light, a Scripps Research Institute team has created a unique library of dozens of synthetic compounds to test for biomedical potential. Already, one of the compounds has shown great promise in inhibiting replication of HIV particles and fighting inflammation.
Researchers have identified how the hormones progesterone and estrogen interact to increase cell growth in normal mammary cells and mammary cancers, a novel finding that may explain why postmenopausal women receiving hormone replacement therapy with estrogen plus progestin are at increased risk of breast cancer.
Kudzu, a medicinal plant, has long thought to reduce alcohol dependence, but the precise mechanism remains a mystery. Recent research from the McLean Hospital shows that pre-treatment with kudzu extract had little to no effect on the participant's behavioral, physical or cognitive performance.
Mutant presenilin is infamous for its role in the most aggressive form of Alzheimer's disease -- early-onset familial Alzheimer's -- which can strike people as early as their 30s. In their latest study, researchers at the Salk Institute uncovered presenilin's productive side: It helps embryonic motor neurons navigate the maze of chemical cues that pull, push and hem them in on their way to their...
Women who were either in the transition to menopause or postmenopausal experienced a reduction in the frequency and severity of menopausal hot flashes with the use of the antidepressant medication escitalopram, compared to women who received placebo, according to a study in the January 19 issue of JAMA.
While monogamy is often touted as a way to protect against disease, young couples who say they have discussed monogamy can't seem to agree on what they decided. And a significant percentage of those couples who at least agreed that they would be monogamous weren't.
Emergency medicine researchers with the University of Cincinnati (UC) are advocating a new strategy for diagnosing a common but dangerous condition in the emergency room.
Researchers at Northwestern University have placed nanocrystals of rock salt into lead telluride, creating a material that can harness electricity from heat-generating items such as vehicle exhaust systems, industrial processes and equipment and sun light more efficiently than scientists have seen in the past.
UNC scientists who study how cells repair damage from environmental factors like sunlight and cigarette smoke have discovered how a "chaperone" enzyme plays a key role in cells' ability to tolerate the DNA damage that leads to cancer and other diseases.
Researchers have determined the structure and mechanism of an enzyme that performs the crucial first step in the formation of cholesterol and a key virulence factor in staph bacteria.
Severe asthma in early childhood may lead to premature loss of lung function during adolescence and more serious disease during adulthood, researchers at Emory University School of Medicine report. Early identification and treatment of children with severe asthma is important to help stem asthma progression.
Maintaining periodontal health may contribute to a healthy respiratory system, according to research published in the Journal of Periodontology. A new study suggests that periodontal disease may increase the risk for respiratory infections, such as chronic obstructive pulmonary disease (COPD) and pneumonia. These infections, which are caused when bacteria from the upper throat are inhaled into the...
New technology providing the first view of DNA damage throughout the entire human genome developed by Cardiff University scientists could offer a valuable new insight into the development and treatment of conditions like cancer.
Keeping older drivers safe behind the wheel is the goal of a successful program at the University of California, San Diego School of Medicine now expanding into additional counties. A team of experts from the School's Trauma Epidemiology and Injury Prevention Research Center has received two grants to expand the program, which focuses on interventions to assist older drivers who may be at risk for...
National Jewish Health has been issued a US patent claiming a method to desensitize B cells by inactivating antigen receptors on their surfaces. The method, discovered by John Cambier, PhD, Chairman of the Integrated Department of Immunology at National Jewish Health, holds promise for treatment of B-cell mediated diseases, such as lymphoma and leukemia, rheumatoid arthritis, lupus and rejection...
Physicists and bioengineers have developed an optical instrument allowing them to control the behavior of a worm just by shining a tightly focused beam of light at individual neurons inside the organism.
A complex sugar may someday become one of the most effective weapons to stop the spread of cholera, a disease that has claimed thousands of lives in Haiti since the devastating earthquake last year.
