Chromosome glue repairs damaged DNA
When a strand of DNA breaks in the body's cells, it normally does not take long until it has been repaired. Now researchers at the Swedish medical university Karolinska Institutet have discovered a new mechanism that helps to explain how the cell performs these repairs. The results are presented in Science. view more (2007-07-16)

Gene study shows three distinct groups of chimpanzees
The largest study to date of genetic variation among chimpanzees has found that the traditional, geography-based sorting of chimps into three populations—western, central and eastern—is underpinned by significant genetic differences, two to three times greater than the variation between the most different human populations. view more (2007-04-23)
The gigantic respiration of crystalline solids
Previously, only amorphous polymer materials approached such levels of performance. On the other hand, these "gigantic respiration" and their respiration, which takes place at constant overall shape, is reversible. This discovery, of interest for numerous industrial applications, is published in the journal Science on March 30, 2007. view more (2007-04-02)
Mitochondrial genes move to the nucleus
Why mitochondrial genes ditch their cushy haploid environs to take up residence in a large and chaotic nucleus has long stumped evolutionary biologists, but Indiana University Bloomington scientists report in this week's Science that they've uncovered an important clue in flowering plants. view more (2007-03-23)
New thinking needed on helping kids avoid or cope with homesickness
A new report urges parents and children's doctors to change their thinking about homesickness among children, to see it as a nearly universal but highly preventable and treatable phenomenon - rather than an unavoidable part of childhood. view more (2007-01-02)
Stress fast tracks puberty
Stress, such as that brought on by parental separation and absentee fathers, fast tracks puberty, say researchers in the Journal of Epidemiology and Community Health. view more (2006-10-19)
MIT's molecular sieve advances protein research
New MIT technology promises to speed up the accurate sorting of proteins, work that may ultimately aid in the detection and treatment of disease. view more (2006-09-14)
High-value chemicals produced from ethanol feedstocks could boost biorefinery economics
Biorefineries developed to produce ethanol from cellulose sources such as trees and fast-growing plants could get a significant economic boost from the sale of high-value chemicals - such as vanillin flavoring - that could be generated from the same feedstock. view more (2006-09-11)
NASA finds direct proof of dark matter
Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies. The discovery, using NASA's Chandra X-ray Observatory and other telescopes, gives direct evidence for the existence of dark matter. view more (2006-08-22)
Proba-3: ESA's first step towards formation flying
Proba-3 is the third in ESA's series of missions for validating developments in space systems while carrying an 'added value' user payload which can directly benefit from the innovations under test. view more (2006-08-10)
First Direct Observations of Spinons and Holons
Working at the Advanced Light Source (ALS) of the U.S. Department of Energy's Lawrence Berkeley National Laboratory, a team of researchers has observed the theoretical prediction of electron "spin-charge separation" in a one-dimensional solid. view more (2006-07-17)
Improving your diet may not help you beat stress
Research published online in the Journal of Proteome Research, shows how improving the diet of rats placed in stressful environments did not normalise their metabolic profile, an indicator of their health. view more (2006-07-06)
Protein connections: A network to understand disease
In the 1990s, the notion of "six degrees of separation" emphasized human linkages that connected people around the world. view more (2006-05-19)
Human and chimp genomes reveal new twist on origin of species
The evolutionary split between human and chimpanzee is much more recent - and more complicated - than previously thought. view more (2006-05-18)
Low-cost microfluidics can be a sticky problem
A deceptively simple approach to bonding thermoplastic microchannel plates together with solvent could be used for low-cost, high-volume production of disposable "lab-on-a-chip" devices, according to researchers from the National Institute of Standards and Technology (NIST) and George Mason University (GMU). view more (2006-05-15)
Magnetic nanoparticles facilitate separations in 'one-pot' multi-step reactions
Using the unique properties of new nanometer-scale magnetic particles, researchers have for the first time separated for reuse two different catalysts from a multi-step chemical reaction done in a single vessel. view more (2006-03-15)
Earth's turbulence stirs things up slower than expected
In a simple world rivers would flow in straight lines, every airplane ride would be smooth, and we would know the daily weather 10 years into the future. But the world is not simple - it is turbulent. view more (2006-03-06)
