Science Sunday: Wrap-up of recent advancements in science from EurekAlert!

Gender linked to development of skin cancer:
Inherent gender differences -- instead of more sun exposure -- may be one reason why men are three times more likely than women to develop certain kinds of skin cancer, say researchers at Ohio State University Medical Center.

Selective amnesia -- How a traumatic memory can be wiped out:
French CNRS scientists in collaboration have shown that a memory of a traumatic event can be wiped out.

New genetic biomarkers could predict coronary heart disease:
New genetic markers may be able to predict whether a person is likely to have coronary heart disease (CAD) in the future. Research shows that people who are pre-diabetic or who have Type 2 diabetes have much shorter telomeres (ends of the chromosome) and, since these people are prone to CAD, an early test could indicate their susceptibility and help them to alter their lifestyle to avoid or delay the onset of the disease.

Preventing cancer without killing cells:
Inducing senescence in aged cells may be sufficient to guard against spontaneous cancer development, according to a paper published online this week in EMBO reports. It was previously unknown whether cellular senescence or programmed cell death -- apoptosis -- was the more important safeguard mechanism for suppressing tumours arising from dysfunctional telomeres.

Intelligent materials to regenerate bone tissue:
The European Nanobiocom project, led by INASMET-Tecnalia with the help of others, is working on the regeneration and repair of bone tissue. The goal is to come up with a substitute for bone tissue that can put the bone right and regenerate in such a way that it carries out similar functions as in its natural state.

NYU scientists identify how development of different species uses same genes with distinct features:
Biologists at New York University have identified how different species use common genes to control their early development and alter how these genes are used to accommodate their own features.
