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
Fndings in mice hold implications for human disorders
New research at the University of North Carolina at Chapel Hill offers an important contribution to a new wave of thinking in genetics: the idea that not all human disease states are due to alterations in DNA sequence.
A growing body of research on these “epigenetic” changes are leading geneticists to rethink the conventional view that all human disease is fundamentally tied to DNA sequence variation (changes in the actua
Scottish company IceRobotics will develop a new generation of dairy farm robots, working in a way that is similar to an elephants 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
Children’s viewing of violent TV shows, their identification with aggressive same-sex TV characters, and their perceptions that TV violence is realistic are all linked to later aggression as young adults, for both males and females. That is the conclusion of a 15-year longitudinal study of 329 youth published in the March issue of Developmental Psychology, a journal of the American Psychological Association (APA). These findings hold true for any child from any family, regardless of the child’s init
Viral enzyme clear cuts forest of protective molecules on lung cells in mice; blocking that enzyme reduces illness and incidence of death from subsequent infection by Streptococcus pneumoniae
Investigators at St. Jude Childrens Research Hospital have shown in mice how the potentially deadly cooperation between influenza virus and bacterial pneumonia infections can be foiled, even if treatment is delayed and flu virus levels in the lung have peaked.
The St.
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
