Study shows life-threatening reactions from accidental ingestion can be avoided
A new medication could help most people with peanut allergies avoid life-threatening allergic reactions, according to a report in the March 14 issue of the New England Journal of Medicine. A research team led by Donald Leung, M.D., Ph.D. of National Jewish Medical and Research Center, and Hugh Sampson, M.D. of Mount Sinai School of Medicine, found that treatment with an anti-IgE antibody raised the average
North Carolina State University poultry scientists have developed a powerful new tool to aid the understanding of how chicken embryos develop.
The research of Dr. Paul Mozdziak, assistant professor of poultry science, and Dr. James Petitte, professor of poultry science, resulted in successfully transferring a gene into a chicken and establishing a line of chickens carrying that specific marker gene.
Currently, the chick embryo is often used as a model to understand normal a
Mayo Clinic researchers have proven for the first time that cells produced by the bone marrow can form new heart-muscle cells in adults, providing an important boost to research that could enable the body to replace heart muscle damaged by heart attack. The findings are now available online and will be published tomorrow in Circulation: Journal of the American Heart Association.
“Until recently, the heart has been seen as an organ that cannot be healed,” says Noel Caplice, M.D., the Mayo Cli
An advanced technique for analysing radar images shows tremendous promise for scientists studying forests, agriculture, ice and other terrain types, but experts at a recent ESA workshop cautioned that research work is needed before practical applications can be developed.
More than 120 scientists and researchers from 20 countries gathered recently at ESA’s ESRIN facility in Frascati, Italy, for a three-day workshop to share the latest results on scientific tests and potential applications of
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
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
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
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’
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
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 Children’s 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.
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
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
Genetically altered bacterial viruses appear to be more effective than naked DNA in eliciting an immune response and could be a new strategy for a next generation of vaccines that are easy to produce and store, say researchers from Moredun Research Institute in the United Kingdom.
“In theory, millions of doses can be grown within a matter of days using simple equipment, media and procedures,” says John March, one of lead researchers presenting findings at the American Society for Microbiol
UK astronomers Elizabeth Stanway, Andrew Bunker and Richard McMahon at the Institute of Astronomy, University of Cambridge, England, have used three of the most powerful telescopes in existence to identify some of the farthest galaxies yet seen. But at the same time, they have encountered a cosmic conundrum: it looks as if there were fewer galaxies forming stars at this early stage in the history of the Universe than in the more recent past. Their results, which will be published in the Monthly Notic
A lot of attention has been paid in recent years to the asteroid threat issue. The International Asteroid Patrol has been set up to monitor the flight of potentially dangerous celestial rocks in visual diapason. However, the accuracy of optical methods for determining the trajectory leaves much to be desired. That accounts for inaccuracy of numerous forecasts predicting the date when the space “killer” is to collide with the Earth.

While studying mice with a mutant gene whose counterpart causes inherited glaucoma in humans, researchers have discovered a second gene mutation that worsens the structural eye defect that causes this type of glaucoma.
The newly discovered gene mutation affects production of L-DOPA. The researchers suggest that it might be feasible to prevent glaucoma by administering L-DOPA, which is used in treating Parkinson’s disease.
