Two galaxies perform an intricate dance in this new Hubble Space Telescope image. The galaxies, containing a vast number of stars, swing past each other in a graceful performance choreographed by gravity.
A PET scan that measures uptake of sugar in the brain significantly improves the accuracy of diagnosing a type of dementia often mistaken for Alzheimer's disease, a new study has found. The scan, FDG-PET, helped six doctors from three national Alzheimer's disease centers correctly diagnose frontotemporal dementia and Alzheimer's in almost 90 percent of cases.
Spending just 10 minutes talking to another person can help improve your memory and your performance on tests, according to a new study. The higher the level of participants'social interaction, researchers found, the better their cognitive functioning. This relationship was reliable for all age groups, from the youngest through the oldest.
Men with 'low risk'prostate cancer who miss more than two radiation treatments in an eight week treatment face an increased chance of their cancer recurring. That is the conclusion of a new study examining more than 15 years of data and nearly 1,800 patients treated at Fox Chase Cancer Center in Philadelphia.
Fever is an effective defence against disease, but new research suggests that not all animals use it when exposed to infection. A new study found large differences in fever responses among closely related species of mice and suggests that an animal's reproductive strategy could explain some of this intriguing variation.
Students, athletes and performing artists are often advised to imagine themselves performing successfully. That strategy is believed to motivate them for future exams, games, and shows. But is that motivation influenced by what perspective they take when imagining their performance?
Large-scale fires in a western or southeastern state can pump as much carbon dioxide into the atmosphere in a few weeks as the state's entire motor vehicle traffic does in a year, according to a new article.
If a woman is overweight when she becomes pregnant, the probability is much greater that her child will evince ADHD-like symptoms when he/she reaches school age, according to a new Nordic study. Expectant mothers who were already overweight and moreover gained a considerable amount of weight during the course of the pregnancy ran a greater risk of having a child who would later show signs of ADHD than did women of normal weight who experienced the same weight gain during pregnancy.
A new communication factor that enables bacteria to "talk to each other"and causes their death could have significant consequences leading to development of a new class of antibiotic medications.
A drug commonly used to halt premature labor may be associated with brain damage and intestinal issues in premature babies, according to a new analysis in the American Journal of Obstetrics and Gynecology.
Scientists at the National Physical Laboratory have released new research results that could affect how we measure a kilogram -- the last SI unit based on a manufactured object. The International System of Units (SI) is the foundation for all our measurements from the beer in your pint to the gap between the tick and the tock on your clock.
Lack of legal clarity and clinical guidelines can put health-care professionals in a very difficult position when it comes to resuscitating hopelessly ill patients. But using "slow codes"-- where resuscitation is carried out too slowly to be effective -- can prolong death and suffering, according to a recent review.
Supermassive black holes can produce powerful winds that shape a galaxy and determine their own growth, confirms a group of scientists. The scientists for the first time, observed the vertical launch of rotating winds from glowing disks of gas, known as accretion disks, surrounding supermassive black holes in the centers of galaxies.
Some molecular interactions on cell surfaces may have a "memory"that affects their future interactions. The report could lead to a re-examination of results from certain single-molecule research.
