Targeted therapy for gastric cancer possible

Gastric cancer, otherwise known as stomach cancer, does not respond well to existing treatments and it is currently the third leading cause of cancer death in the world (after lung and liver cancer). Researchers have discovered that certain drugs, currently used to treat breast, ovarian and pancreatic cancers, could also be used to treat certain gastric cancers with a particular pattern of mutations (genomic molecular fingerprint).

What do you get when two neutron stars merge?

Led by Chris Fryer of the University of Arizona and the Los Alamos National Laboratory, a group of researchers undertook a highly collaborative study to better understand the fates of neutron star mergers.

The merger of two neutron stars (a NS–NS merger) is suspected to be the most likely source of short-duration gamma-ray bursts (GRBs) — powerful explosions that can be seen from billions of light-years away. But whether a GRB is launched is dependent on what remnant is created by the merging NSs. Do they form another NS? Or a black hole (BH)?

Tiny magnets could work in sensors, information encoding

Researchers have created a nanoscale, artificial
magnet, LANL image.

Scientists from Los Alamos National Laboratory and collaborators have realized a nanoscale, artificial magnet by arranging an array of magnetic nano-islands along a geometry that is not found in natural magnets.

"Each nano-island is similar to a refrigerator magnet, with a north and a south pole at its tips," said Los Alamos physicist Cristiano Nisoli. "Unlike a refrigerator magnet, however, it can change its magnetization by flipping north and south, through use of either applied fields or thermal fluctuations.

UNM, LANL researchers team up to beef up fuel cell performance

Better batteries and more efficient fuel cells are two holy grails of energy development.  Fuel cells convert hydrogen or biogas into electricity while emitting only heat and water, making them the darlings of a new energy economy that seeks to reduce pollutants from petroleum-fed cars.

Scientists from The University of New Mexico and Los Alamos National Laboratory have combined their research expertise to create a micro sandwich of gold, DNA and carbon tubes that they think could eventually beef up fuel cell performance.

LANL team receives NNSA awards for exceptional work

National Nuclear Security Administrator Lt. Gen. (retired) Frank G. Klotz presented five Los Alamos National Laboratory members awards for their exceptional work in a large-scale, on-site field exercise held in Jordan to evaluate progress in the development of the Comprehensive Nuclear-Test-Ban Treaty.
