Monthly ingestion appears to boost peanut tolerance
Children who outgrow peanut allergy have a slight chance of recurrence, but researchers from the Johns Hopkins Children’s Center report that the risk is much lower in children who frequently eat peanuts or peanut products.
In a study published in the November issue of the Journal of Allergy and Clinical Immunology, the Hopkins team recommends that children who outgrow peanut allergy eat concentrated forms of peanut
Although particulate air pollution has been blamed for a wide variety of negative health effects, a three-year study of asthmatic children in Denver, published in the November Journal of Allergy and Clinical Immunology, indicates that it does not lead to significant worsening of asthma during the pollution-heavy winter months. Upper respiratory infections, however, were associated with a significant decline in lung function, asthma symptoms and asthma exacerbations.

Fossils from the sea floor illuminate the relationship between local and global diversity, and these relationships may help us understand the effects of global climate change on species diversity.
“Looking at fossils can tell you something about the controls on global diversity, but so much of the investigation of the fossil record has looked only at global compilations of fossil species,” says Dr. Mark E. Patzkowsky, associate professor of geosciences. “Recently, a few studies ha

Invading Trout Reduce Forest Spiders by Altering the Stream Food Web That Supplies Their Prey
A team of researchers from the U.S. and Japan have shown that exotic species can have strong effects that degrade not only the ecosystems they invade, but also spread to adjacent ecosystems as well. Colden Baxter, Kurt Fausch and Phillip Chapman from Colorado State University collabo
Scientists from three countries study innovative DNA transport element
Treating genetic diseases by introducing functional genes into the human organism: researchers from three European countries are aiming for a breakthrough in this process, known as gene therapy, using a new methodology. The network of scientists, including the German Research Centre for Biotechnology in Braunschweig (GBF), is working to further develop a certain type of DNA element, called an episome, for this
Improved safety at sea for cruise ship passengers and crews will be the outcome of a research and development project, funded with the help of over €1.7m (euros) from the EU’s Framework Programme.
SEA-AHED (Simulation environment and advisory system for on-board help, and estimation of manoeuvring performance during design) was a 39-month project to produce a technology system that can predict the course of cruise ships within 10 to 20 metres – far more accurately than anything c
The launch of the biggest TV boom in history, the digital terrestrial services that form the platform for the phenomenally successful Freeview, was made possible thanks to a grant of 6.45 million euros from the EU’s Framework Programme.
The VALIDATE (Verification and Launch of Integrated Digital Advanced Television in Europe) project, technically underpinned by a BBC-led partnership, gave the UK the technical confidence to launch digital terrestrial TV in 1998. This technical expe
A system to help assess the impact of proposed action, or inaction, in dealing with disabled and drifting ships is being developed with the help of grant of €1.25m (euros) from the EU’s Framework Programme.
The objective of SAFETOW (Strategic Aid for Escort Tugs at Work), a 36 month project with a total cost of €2.24m (euros), is to provide tools to help ships Masters control their vessels if they become disabled. It will also help Masters of salvage and escort tugs to take de
Today, a group of physicists published the most compact and elegant explanation of one of nature’s simplest phenomena: the way light behaves in the sky above us. This research appears today (Tuesday, 9th November) in the New Journal of Physics, published jointly by the Institute of Physics and Deutsche Physikalische Gesellschaft (German Physical Society).
Michael Berry and Mark Dennis from the University of Bristol, in collaboration with Raymond Lee of the US Naval Academy, have
UC Riverside Researchers Find that Fish Living in High-Predator Environments Challenge Classic Evolutionary Theories
Classic evolutionary theories of senescence, or the evolution of the rate at which organisms deteriorate as they age, have been challenged by the findings of researchers at the University of California, Riverside.
In the 1950s, Peter Medawar, winner of a Nobel Prize for medicine, and George Williams, a renowned evolutionary biologist, developed theories fo
In an interdisciplinary endeavor at the University of California, Santa Barbara, a team of researchers in physics and biology have made a discovery at the nanoscale level that could be instrumental in the production of miniaturized materials with many applications. Dubbed a “living necklace,” the finding was completely unexpected.
This discovery could influence the development of vehicles for chemical, drug, and gene delivery, enzyme encapsulation systems and biosensors, circuitr
NASA scientists recently found the El Nino Southern Oscillation (ENSO) is the main driver of the change in rain patterns all around the world.
The NASA and Japan Aerospace Exploration Agency (JAXA) Tropical Rainfall Measuring Mission (TRMM) satellite has enabled scientists to look around the globe and determine where the year-to-year changes in rainfall are greatest. The TRMM is a joint mission between NASA and JAXA designed to monitor and study tropical rainfall.

Doctors must choose and manage ICD patients carefully
Implanted devices that can shock a failing heart back into regular rhythm do an excellent job of keeping patients alive, two new University of Michigan studies find. The research also suggests that doctors may be able to categorize their patients according to their individual risk factors, to determine who might get the largest benefit from the expensive devices, called implanted cardiac defibrillators, or ICDs. The studie
Dynamic susceptibility contrast (DSC) MRI allows physicians to differentiate between cerebral abscesses—inflamed areas in the brain caused by infection—and malignant brain tumors without surgery, says a new preliminary study by researchers from Duke University Medical Center in Durham, NC.
For the study, the researchers analyzed eight patients who underwent DSC MRI—four with cerebral abscesses and four with malignant brain tumors. DSC MRI is used to measure blood volume in brain
Protease inhibitors used to treat HIV-1 infection may also be effective for treatment or prevention of malaria, according to a study published in the December 1 issue of The Journal of Infectious Diseases, now available online. The study found protease inhibitors inhibited the growth of P. falciparum, the malaria parasite that causes most disease. These findings may also expose a previously unexplored vulnerability in the parasite that could lead to a new class of anti-malarial drug. While the eff
Drug discovery researchers at Northwestern University have developed a new class of compounds that have the potential to reduce the inflammation of brain cells and the neuron loss associated with Alzheimer’s disease.
The new class of compounds are aminopyridazines. The original compound, called MW01-070C, is used in an injectable form. More recently developed compounds, such as MW01-2-151WH and MW01-5-188WH, can be taken by mouth.
The compounds were designed and sy
