A research team led by a University of Iowa investigator has generated DNA-like compounds that effectively inhibit the cells responsible for systemic lupus erythematosus -- the most common and serious form of lupus. There currently is no cure for this chronic autoimmune condition that damages the skin, joints and internal organs and affects an estimated one million Americans.
GAINESVILLE, Fla. ? Focusing HIV drug development on immune cells called macrophages instead of traditionally targeted T cells could bring us closer to eradicating the disease, according to new research from University of Florida and five other institutions.
The melting of the Greenland Ice Sheet this century may drive more water than previously thought toward the already threatened coastlines of New York, Boston, Halifax and other cities in the northeastern United States and Canada, according to new research.
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.
HOUSTON -- (May 27, 2009) -- A new analysis of the processes that constantly stir the Earth's deep mantle is helping to explain how the mantle holds onto a portion of ancient noble gases that were trapped during the Earth's formation.
A recent study finds that the antidepressant effects of drugs like Prozac involve both neurogenesis-dependent and -independent mechanisms, a finding that may lead to development of better treatments for depression and anxiety.
A new study demonstrates that when faced with a difficult decision, the human brain calls upon multiple neural systems that code for different sorts of behaviors and strategies.
DURHAM, N.C. ? Watching people's brains in real time as they handle a set of decision-making problems can reveal how different each person's strategy can be, according to neuroscientists at the Duke University Medical Center.
BOULDER--Melting of the Greenland ice sheet this century may drive more water than previously thought toward the already threatened coastlines of New York, Boston, Halifax, and other cities in the northeastern United States and in Canada, according to new research led by the National Center for Atmospheric Research (NCAR).
A group of researchers from the LGC Chemical Metrology Laboratory in the United Kingdom and the University of Oviedo, Spain, have come up with a method to detect how the proportions of isotopes in a chemical element (atoms with an equal number of protons and electrons but different numbers of neutrons) vary throughout the length of a single hair.
A study forthcoming in the Journal of Labor Economics suggests that high-quality teachers tend to leave schools that experience inflows of black students. According to the study's author, C. Kirabo Jackson (Cornell University), this is the first study to show that a school's racial makeup may have a direct impact on the quality of its teachers.
A new way of assessing professionalism among medical students could help to make better doctors, a new research study suggests.
Greater statutory protection, support from regulatory bodies and, above all, a culture change to encourage whistleblowing are required to protect patients and clinicians, according to an editorial published on bmj.com today.
HOUSTON ― Novel chemotherapy and biological agents for metastatic colorectal cancer, combined with surgical advances in liver resection, have resulted in a dramatic increase in survival for patients with advanced disease, according to researchers at The University of Texas M. D. Anderson Cancer Center.
ROCHESTER, Minn. -- Mayo Clinic researchers are reporting positive results in early leukemia clinical trials using the chemical epigallocatechin gallate (EGCG), an active ingredient in green tea.
