Methylation: Key to chemo epigenetics

Date: Mar 15, 2014

Author: David Bradley

Chemotherapy for breast cancer comes with inevitable acute side effects, but it can also leave a long-term epigenetic imprint on the DNA of the patient's normal white blood cells. Research to scan and analyse hundreds of thousands of putative methylation sites that might be involved in this process could lead to new understanding of the effects of cancer therapy.

Mars: The watery shape of things to come

Date: Feb 15, 2014

Author: David Bradley

Streaks that periodically appear on the surface of Mars could be due to water. A spectroscopic study of these recurring slope lineae (RSL) has not revealed the presence of water nor salts that might be soluble residues. However, the presence of spectral lines due to iron(III) and iron(II) minerals may hint at an aqueous process offering a tantalizing dip of the toe into the Martian waters.

When closure gels: Wound healing

Date: Dec 15, 2013

Author: David Bradley

Effective wound closure is vital to avoid significant blood loss following injury and to reduce the risk of infection. Researchers in the US have developed a novel gel that can seal wounds rapidly but be dissolved subsequently to allow the wound to be opened gently if surgery is necessary. Analytical assessment of the associated rheological data demonstrate efficacy.
