ANN ARBOR, Mich.?By using ultrafast laser pulses to slice off pieces of chromosomes and observe how the chromosomes behave, biomedical engineers at the University of Michigan have gained pivotal insights into mitosis, the process of cell division.
Their findings could help scientists better understand genetic diseases, aging and cancer.
An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester.
PASADENA, Calif.?Theta oscillations are a type of prominent brain rhythm that orchestrates neuronal activity in the hippocampus, a brain area critical for the formation of new memories. For several decades these oscillations were believed to be "in sync" across the hippocampus, timing the firing of neurons like a sort of central pacemaker.
The popular belief that healthy eating starts at home and that parents' dietary choices help children establish their nutritional beliefs and behaviors may need rethinking, according to a study by researchers at the Johns Hopkins Bloomberg School of Public Health. An examination of dietary intakes and patterns among U.S.
(ORLANDO) ? Though the growing shift toward oral chemotherapy agents offers cancer patients greater freedom and independence during their treatment, physicians say use of the new medications also poses more chances for patients to skip doses, miss prescription refills, and take their drugs in a dangerous way.
Researchers from the Ludwig Institute for Cancer Research at the University of California, San Diego School of Medicine have uncovered a remarkable property of the contractile ring, a structure required for cell division. Understanding how the contractile ring works to divide the cell may facilitate development of therapies to prevent uncontrolled cell division in cancer.
President Barack Obama and Energy Secretary Steve Chu are consistent in their message that when it comes to transportation fuels, carbon-neutral biofuels as an alternative to gasoline are coming. While the focus of a shift from gasoline to biofuels has been on global warming, such a shift could also impact human health.
BUFFALO, N.Y. -- University at Buffalo researchers have demonstrated for the first time that injecting adult bone marrow stem cells into skeletal muscle can repair cardiac tissue, reversing heart failure.
PITTSBURGH, May 28 ? When faced with a terminal illness, African-American seniors were two times more likely than whites to say they would want life-prolonging treatments, according to a University of Pittsburgh study available online and published in the June issue of the Journal of General Internal Medicine.
CHAPEL HILL, N.C. ? A landmark clinical trial led by a University of North Carolina at Chapel Hill researcher concludes that radiofrequency ablation is an effective treatment for dysplasia in people with Barrett's esophagus, a condition that can lead to deadly gastrointestinal cancer.
GAINESVILLE, Fla. --- As the frozen soil in the Arctic thaws, bacteria will break down organic matter, releasing long-stored carbon into the warming atmosphere.
At the same time, plants will proliferate, nurtured by balmier temperatures, more nutrients from decomposing soil and the increasing abundance of the greenhouse gas they depend on for growth.
COLUMBIA, Mo. ? A plant's immune system protects the plant from harmful pathogens. If the system overreacts to pathogens, it can stunt plant growth and reduce seed production. Now, University of Missouri researchers have identified important suppressors that negatively regulate the responses of the immune system in the plant species Arabidopsis thaliana.
Hours after Hurricane Ike roared ashore in Texas, more than two million homes were without power, which left some scrambling to preserve food and others looking for ways to entertain children, a move that proved to be, in some instances, poisonous.
Spring marks baseball season for more than 19 million children and adolescents who play each year as part of a team or in backyards throughout the United States. The good news for these players is that the number of injuries from the sport is on the decline.
ROCHESTER, Minn. - A short, preoperative team briefing prior to cardiac surgery - where each person on the team speaks - improves communication and reduces errors and costs, according to a pilot study conducted at Mayo Clinic.
