Rising skin cancer rates are more likely to affect wealthy people, says 12-year review

...the general increase in incidences of skin cancer, coupled with ageing populations, will place greater demands on dermatology and other related specialties over the coming years. “The number of people aged 60 and over is set to rise by more than a half by 2030 and 80 per cent of all skin cancers occur in ...

Genetic roots of bipolar disorder revealed by first genome-wide study of illness

...from pronounced over-excitement and elation, often coupled with severe irritability, to depression. Children also may have the condition, usually in a more severe form than adults. "We're beginning to get a foothold on the genetics of this complex brain disorder," said NIMH Director Thomas R. Insel, MD. ...

...n a very stable fashion. The Korean researchers coupled spermine to the vitamin folic acid and packed these hybrid molecules into the capsule's pockets. This gave them capsules with a surface covered with folic acid molecules. What for? Many tumors have a significantly increased number of folic acid recep...

Africa's first large-scale HIV vaccine study launches

...for this trial due to the high levels of infection coupled with the good clinical infrastructure, including internationally recognized immunology laboratories, a well-established national vaccine initiative and experience in running clinical trials," said James Kublin, M.D., M.P.H., one of study's lead inves...

Mailman School of Public Health researchers report blood DNA can be early predictor of liver cancer

...C. According to the study findings, these factors coupled with smoking and alcohol status, and alterations found in this study in serum DNA, resulted in an overall predictive accuracy of 89% for detection of HCC. “These are extremely encouraging findings,?says Regina Santella, PhD, professor of Environm...

Study to explore using magnets to correct 'sunken chest'

...ich a magnet attached to the child's breastbone is coupled with a second one outside the chest that creates a steady, controlled, outward pull on the internal magnet to reshape the bone, cartilage and chest wall. The procedure marks one of the first times magnets have been embedded inside the body to tre...

Instruction manual for creating a molecular nose

...lected by the researchers were a type of G-protein coupled receptor taken from brown rats. The scientists were also able to prove that the odorant receptors maintained their biological functions by demonstrating the binding of odorants to the receptors. "We now have something akin to an instruction manual on...

UBC researchers reveal dwarf aquatic plants' hidden ancestry

...d Food Systems. "And it took DNA sequence evidence coupled with a critical re-examination of anatomy to assign these plants to their proper place in the plant evolutionary family tree." Graham and his PhD students Hardeep Rai and Jeffery Saarela, who is now a research scientist at the Canadian Museum of N...

Prenatal cocaine's lasting cellular effects

.... Incredibly high levels of cocaine -- usually coupled with the abuse of other drugs -- can lead to premature labor, preterm birth and low birth weight, Stanwood said. "But in women who have abused relatively low recreational doses of cocaine, it is actually very hard to distinguish those children at...

Conceptualizing a cyborg

...reate transplantable living nervous tissue already coupled to electrodes. Like an extension cord, of sorts, the non-electrode end of the lab-grown nervous tissue could integrate with a patient's nerve, relaying the signals to and from the electrode side, in turn connected to an electronic device. This ...

CSIRO imagery shows Outer Great Barrier Reef at risk from river plumes

...the accumulated material in the creeks ands rivers coupled with increased sediment runoff from the land is causing a significant transport of terrestrial material to all areas of the affected reefs and reef waters. Managers of the GBR have long been examining the effects of run-off of sediments, includin...

Novel laboratory technique nudges genes into activity

...mosome level. The new UT Southwestern research, coupled with that from 2005, demonstrates a shift away from conventional thinking about how gene expression is naturally controlled, as well as how scientists might be able to exploit the process to develop new drug targets, Dr. Corey said. For example, c...

Theory of oscillations may explain biological mysteries

...ns for their subject. But it is already clear that coupled oscillating biological populations can give rise to potentially important effects such as “synchronized chaos? the interaction between two weakly competing consumers of a food resource can be transformed by the arrival of a third competitor to provid...

Ongoing collapse of coral reef shark populations

... to protect shark populations. These observations, coupled with population modeling showing ongoing, rapid declines in population size in fished areas, lead the authors to conclude that reef sharks are approaching “ecological extinction”—that is, becoming so rare that they can no longer perform their natural...

Researchers to develop active nanoscale surfaces for biological separations

...ered that the mobility of DNA molecules is closely coupled to the movement of the underlying lipid bilayer. "The advantage of these surfaces is that they can be actively modified," Kane said. "Thus by changing the temperature, shining light, or applying an electric field, we propose to change the behavior...

The first tree genome is published: Poplar holds promise as renewable bioenergy resource
