Skin color gives clues to health

Researchers from the universities of Bristol and St. Andrews in the UK have found that the color of a person's skin affects how healthy and therefore attractive they appear, and have found that diet may be crucial to achieving the most desirable complexion. The work will be published in the December issue of Springer's International Journal of Primatology.

Nanoparticles do not damage DNA across barriers by signaling molecules

QED induced radiation's picture

Ionizing radiation emitted by nanoparticles damages the DNA by penetrating barriers instead of the nanoparticle signaling across the barrier for the DNA to be damaged

Switching immunosuppressants reduces cancer risk in kidney

Switching to a newer type of immunosuppressant drug may reduce the high rate of skin cancer after kidney transplantation, according to research being presented at the American Society of Nephrology

New UK study suggests minimal relationship between cannabis and schizophrenia or psychosis

Last year the UK government reclassified cannabis from a class C to a class B drug, partly out of concerns that cannabis, especially the more potent varieties, may increase the risk of schizophrenia in young people. But the evidence for the relationship between cannabis and schizophrenia or psychosis remains controversial.

Over half of cot deaths occur while co-sleeping

More than half of sudden unexplained infant deaths occur while the infant is sharing a bed or a sofa with a parent (co-sleeping) and may be related to parents drinking alcohol or taking drugs, suggests a study published on bmj.com today.

New coastland map could help strengthen sea defenses

The 'Coastland Map' produced by scientists from Durham University and published in the Journal GSA Today, charts the post Ice-Age tilt of the UK and Ireland and current relative sea-level changes. According to the map, the sinking effect in the south could add between 10 and 33 per cent to the projected sea-level rises caused by global warming over the next century. *

Smoking during pregnancy puts children at risk of psychotic symptoms

Mothers who smoke during pregnancy put their children at greater risk of developing psychotic symptoms in their teenage years.

New research published in the October issue of the British Journal of Psychiatry shows a link between maternal tobacco use and psychotic symptoms.

New CO2 data helps unlock the secrets of Antarctic formation

The link between declining CO2 levels in the earth's atmosphere and the formation of the Antarctic ice caps some 34 million years ago has been confirmed for the first time in a major research study.

Study results raise questions about vertebroplasty for osteoporotic spinal compression fractures

ROCHESTER, Minn. -- A new study led by Mayo Clinic researchers has found that relief of pain from vertebral compression fractures, as well as improvement in pain-related dysfunction, were similar in patients treated with vertebroplasty and those treated with simulated vertebroplasty without cement injections.

Blood flow in Alzheimer's disease

Researchers have discovered that the enzyme, endothelin converting enzyme-2 (ECE-2), may cause the decrease in blood flow in the brain seen in Alzheimer's disease and contribute to progression of the disease.

University has grand designs to build a house of straw

Could straw houses be the buildings of the future?

That's what researchers at the University of Bath will be testing this summer by constructing a "BaleHaus" made of prefabricated straw bale and hemp cladding panels on campus.

Composites for energy

Advanced composite materials are playing a vital role in improved design and reduced operating costs for renewable energy technologies. Research presented today [Tuesday 30 June] will highlight how wind, marine and solar power could address these challenges within the renewable energy industry.

Molecular typesetting -- proofreading without a proofreader

Researchers at the Universities of Leeds and Bristol (UK) have developed a model of how errors are corrected whilst proteins are being built.

Ensuring that proteins are built correctly is essential to the proper functioning of our bodies, but the 'quality assurance' mechanisms that take place during this manufacturing process are not fully understood.

To protect threatened bat species, street lights out

Slow-flying, woodland bats -- which tend to be at greater risk from extinction than their speedier kin -- really don't like the light, according to a study published online on June 18th in Current Biology, a Cell Press publication.

Manipulating light on a chip for quantum technologies

A team of physicists and engineers at Bristol University has demonstrated exquisite control of single particles of light -- photons -- on a silicon chip to make a major advance towards long-sought-after quantum technologies, including super-powerful quantum computers and ultra-precise measurements.
