Global warming has already caused extinctions in the most sensitive habitats and will continue to cause more species to go extinct over the next 50 to 100 years, confirms the most comprehensive study since 2003 on the effects of climate change on wild species worldwide by a University of Texas at Austin biologist.
Researchers at the Johns Hopkins’ High Throughput Biology Center have invented two new gene “chip” technologies that can be used to help identify otherwise elusive disease-causing mutations in the 97 percent of the genome long believed to be “junk.”
A new study has suggested a novel way of combating diseases related to the immune system, including cancer and autoimmune diseases such as type I diabetes and arthritis. The study, funded by the Wellcome Trust, appears online in the journal Nature.
About one-third of heart attack patients do not receive treatment to open blocked arteries within the recommended 12-hour timeframe after a heart attack. Treatment such as angioplasty or clot-busting drugs may not be given because patients arrive at the hospital too late.
For two consecutive years, researchers examined measures of cardiovascular fitness and self-esteem in sophomore girls attending Trenton Central High School and found students are making better health choices with an intervention program. Low Density Lipoprotein levels — the unhealthy cholesterol — also decreased significantly. WHF Teen Esteem is a gender-specific approach to teen girls’ health and wellness and is meant to be a replacement for traditional gymnastics and health classes.
In the days following a heart attack, patients who have no or mild symptoms and undergo a procedure called angioplasty to mechanically open their totally blocked coronary arteries do not reduce their risk of having another heart attack, going into heart failure or dying, according to the results of a new study.
Children’s ability to distinguish between reality and fantasy depends on their use of contextual cues. The findings of three studies in 400 children between 3 and 6 years of age examined children’s ability to determine whether information they received was factual or not based in truth. By the age of 4, children were able to determine whether something was real or imaginary based on information that related that thing to a familiar entity.
A study of conflict resolution in siblings suggests it is beneficial for children to resolve past disagreements even after the conflict is over. This research was conducted with sixty four pairs of siblings ages 4 to 12. The study concludes that encouraging after-the-fact resolution of differences, parents can help their children develop conflict resolution skills. The study also addressed the factors most likely to affect how conflict is resolved between siblings of different ages.
Six million years ago, chimpanzees and humans diverged from a common ancestor and evolved into unique species. Now UCLA scientists have identified a new way to pinpoint the genes that separate us from our closest living relative ? and make us uniquely human. The Proceedings of the National Academy of Sciences reports the study in its Nov. 13 online edition.
