Scientists identify the neural circuitry of first impressions
Neuroscientists at New York University and Harvard University have identified the neural systems involved in forming first impressions of others.

Addition of chemotherapy to radiotherapy continues to increase survival in patients with brain tumors for up to 5 years
Giving patients with glioblastoma -- the most common and aggressive form of primary brain tumor -- the chemotherapy drug temozolomide in combination with radiotherapy increases their survival compared with those receiving radiotherapy alone and this improvement persists for up to 5 years, according to the final results of the EORTC-NCIC trial, published online first and in the May edition of the Lancet Oncology.

Cleft lip and palate: Genes more important than thought?
Comparing 500,000 snippets of human DNA put scientists from the University of Bonn on the right track.

Protein helps immune cells to divide and conquer
Researchers at the University of California, San Diego School of Medicine, have identified a key protein that is required for immune cells called B lymphocytes to divide and replicate themselves.

Researchers discover gene mutations that cause childhood brain cancer
Researchers funded by the Canadian Cancer Society have discovered eight similar genes that, when mutated, appear to be responsible for medulloblastoma -- the most common of childhood brain cancers.

Pitt researchers describe molecular '2-step' leading to protein clumps of Huntington's disease
In a paper published in the early online version of Nature Structural and Molecular Biology, researchers at the University of Pittsburgh School of Medicine deconstruct the first steps in an intricate molecular dance that might lead to the formation of pathogenic protein clumps in Huntington's disease, and possibly other movement-related neurological disorders.

Stem cells replace stroke-damaged tissue in rats
Effective stem cell treatment for strokes has taken a significant step forward today as scientists reveal how they have replaced stroke-damaged brain tissue in rats.

It's raining pentagons
This week's Nature Materials reveals how an international team of scientists led by researchers at the London Center for Nanotechnology at UCL have discovered a novel one dimensional ice chain structure built from pentagons that may prove to be a step toward the development of new materials which can be used to seed clouds and cause rain.
