'Family friendly' employment policies benefit the middle classes more than low-paid parents
The growth of working parenthood, as encouraged by the government's welfare-to-work and 'family friendly' employment policies, will be experienced very differently by secure middle class families than by poor parents in low-paid jobs.

Scientists map biological changes in Earth's tropical forests
International tropical forest researchers at the Centre for Tropical Forest Sciences (CTFS) including Sean Thomas, forestry professor at the University of Toronto, have established a world network of tropical forest plots to map changes in the biology of one-tenth of the Earth's rainforest tree species - one centimetre at a time.

Could nurse-led care help to unblock NHS beds?
Transferring patients to a low technology unit, where nurses rather than doctors manage recuperation after acute illness, is a safe alternative to conventional care on a general medical ward, finds a study in this week's BMJ.

Galaxy formation not random, says astronomer
Gaze into the vastness of the universe this evening and in all likelihood those galaxies look just as they did five billion years ago, and they didn't get to their locations by random chance, says University of Toronto astronomy professor Raymond Carlberg.

March media highlights: Geology and GSA Today
Highlights include destabilization and collapse of the continental margin associated with the K/T boundary impact event, ocean-atmosphere feedback mechanisms that have affected climate since the early Pliocene, new evidence suggesting the South China continent is older than previously believed, formation of microcontinents, and assessment of volcanic hazards related to potential radioactive waste sites in Japan.

New MRI approach can identify sources of memory loss in humans and mice
Researchers have found a way to pinpoint changes in brain activity that may underlie memory impairment, even before structural damage occurs.

USGS study shows Colorado Plateau coal plentiful
A new U.S. Geological Survey (USGS) assessment of the nation's coal resources shows abundant high quality, low- sulfur coal on federal and private lands in the Colorado Plateau region of Arizona, Colorado, New Mexico and Utah.

Disconnect between skin cells implicated in common skin cancer
A mutation in one molecule that prevents skin cells from making normal connections with each other plays an unexpectedly early and important role in the development of skin cancer suggest researchers at the University of Chicago.

Penn cardiologist reports success in search of gene
Gene responsible for cardiovascular defects in DiGeorge Syndrome, the second leading cause of heart disease in children, was found by researchers from the University of Pennsylvania Medical Center and the Albert Einstein College of Medicine.

How parents were told that their unborn child had an extra or missing sex chromosome - a matter of chance
Some parents are given misleading information about the condition when they are first informed that their unborn child has a sex chromosome anomaly, finds a study in this week's BMJ.

UCLA, Stanford scientists improve techniques for identifying elusive and highly valuable stem cells at the genetic level
A new study led by UCLA researchers increases our understanding of how to pinpoint the elusive and highly valuable stem cells in the human body.

Vitamin A activates gene to guide kidney development
Vitamin A deficiency during fetal development and mutations in ret, the gene that encodes an enzyme called a receptor tyrosine kinase, are associated with kidney malformations in mice and humans.
