Researchers at Cold Spring Harbor Laboratory have discovered three genes that interact with cancerous results in 20 percent of lung cancers. The three genes are located next to each other on human chromosome 14 and two are known to play key roles in fetal lung development.
Researchers have uncovered new evidence in mice that may explain how emotionally charged situations can leave such a powerful mark on our memories. Surges of the stress hormone norepinephrine (also known as noradrenaline) that often accompany strong emotions spark a series of molecular events that ultimately strengthen the connections between neurons, the team reports in the Oct. 5, 2007, issue of the journal Cell, a publication of Cell Press.
Both extensive psychological research and personal experiences confirm that events that happen during heightened states of emotion such as fear, anger and joy are far more memorable than less dramatic occurrences. In a report this week in Cell, Johns Hopkins researchers and their collaborators at Cold Spring Harbor and New York University have identified the likely biological basis for this: a hormone released during emotional arousal “primes” nerve cells to remember events by increasing their chemical sensitivity at sites where nerves rewire to form new memory circuits.
Delivering the highest quality of care for all, as good or better than any country in the world, must be a fundamental goal of the NHS, said Lord Darzi, as he publishes his interim report on the ‘Our NHS, Our Future’ review.
The Oxford Health Alliance (OxHA), a global coalition with the aim of preventing the epidemic of chronic disease, is launching a groundbreaking public health research programme to enhance scientific knowledge about the effectiveness of community interventions in reducing the prevalence of chronic diseases.
It may seem that therapy and law do not share a common bond, but one University of Arizona law professor is making that connection by developing a body of knowledge to prove that legal proceedings can be calming and supportive.
DNA, the biomolecule that provides the blueprint for life, has a lesser-known identity as a stretchy polymer. JILA scientists have found a flaw in the most common model for DNA elasticity, a discovery that will improve the accuracy of single-molecule research and perhaps pave the way for DNA to become an official standard for measuring picoscale forces, a notoriously difficult challenge.
