A Lawrence Livermore National Laboratory astrophysicist, working with an international group of researchers, has discovered that high-energy neutrinos — particles that rarely interact with other matter — are produced in the accretion discs of neutron stars in amounts significant enough to be detected by the next-generation of neutrino telescopes.

Using computer simulations, the team of scientists, which includes Lab astrophysicist Diego Torres, has shown that magnetized, accreting neutron

Studying mice, scientists from Johns Hopkins have successfully prevented a molecular event in brain cells that they’ve found is required for storing spatial memories. Unlike regular mice, the engineered rodents quickly forgot where to find a resting place in a pool of water, the researchers report in the March 7 issue of the journal Cell.

The experiments are believed to be the first to prove that subtly altering the chemistry of a certain protein can profoundly affect a brain cell&#146

Connections seen to X-linked mental retardation and some forms of leukemia

Most of the time, most of the estimated 35,000 genes in the human genome are silent, securely stored away in the tightly coiled structure of chromatin, which makes up chromosomes. Inside chromatin, the DNA is wound around small proteins called histones, making it unavailable to the cellular machinery that would otherwise read its coded genetic information. Specific cell and tissue types are characterized by the

New findings from Queen’s researchers will help experts better predict future drought patterns and water availability in the prairies.

An international research team including biologists Kathleen Laird and Brian Cumming from the Queen’s Paleoecological Environmental Assessment and Research Laboratory (PEARL), and Peter Leavitt from the University of Regina, investigated records of drought over the past 2000 years from lake sediments in the northern Canadian prairie region (Manitoba

Scottish company IceRobotics will develop a new generation of dairy farm robots, working in a way that is similar to an elephant’s trunk, that can milk cows without the presence of the farmer, thanks to an Invention & Innovation award of £98,000 from NESTA (the National Endowment for Science, Technology & the Arts), the organisation that invests in UK creativity and innovation.

While studying for his PhD, Dr Bruce Davies, a senior lecturer at Heriot-Watt University, came up with the id

Authors of a research letter in this week’s issue of THE LANCET highlight how screening for Down’s syndrome based on maternal age and four markers in maternal blood should be used worldwide-the quadruple test is far more effective than screening based on maternal age alone.

Screening for Down’s syndrome is widely practised early in the second trimester of pregnancy (weeks 14 to 22). The quadruple test calculates the risk of a Down’s syndrome term pregnancy from maternal age and the concentr
