A joint study between St Mary’s Hospital, the Paterson Institute, Christie Hospital, The University of Manchester, Guys Hospital in London, and Cambridge University researching breast cancer has found that women with defects in certain genes have a higher chance of developing breast cancer when they are young than previous estimates. The report calls for more family history information to be taken from young women with breast cancer.
Breast cancer affects one woman in 10 to 12 in the UK, a
The way antibiotic resistance spreads and possible problems from genes transferring have been identified by researchers from the Rowett Research Institute in Aberdeen, in new evidence about the way genes pass from one bacterium to another. The research is presented today, Monday 7 April 2003, by Dr Karen Scott at the Society for General Microbiology’s Annual Meeting in Edinburgh.
“We all have a huge number of different bacteria in our guts,” says Dr Scott of the Rowett Research Institute, “a
Designers at Staffordshire University have come up with a solutions package with the potential to make life a lot easier for everyone.
The University’s Centre for Rehabilitation Robotics has spent more than a year involved in PACKAGE, a £1.5 million European Commission project concerned with making small changes to consumer packaging in a bid to improve “openability”
Now after rigorous trials carried out throughout Europe, the Centre are hoping that the world’s bigg
Titan, Saturn’s largest moon, is a mysterious place. Its thick atmosphere is rich in organic compounds. Some of them would be signs of life if they were on our planet. How do they form on Titan? Will they help us to discover how life began on Earth?
ESA’s Huygens probe, arriving at Titan in 2005, will help find answers. Here on Earth, ground-based telescopes are playing their part also. They will help scientists to decide how and where precisely Huygens will land. What will it be –
The principal aim of this PhD paper was the application of the new concepts and ideas of Photonic Crystals and Photonic Bandgap (PBG) to microwave and millimetric circuits and, more concretely, to microstrip circuits which is the most common technology in current use in flat microwave circuits.
Thus, for this thesis, the techniques for optimising the functioning of PBG structures in microstrip technology were studied and the various practical applications of these devices were analysed. For
The benefit of some cancer vaccines may be boosted by treating patients with an antibody that blocks a key protein on immune system T cells, according to a small, preliminary study led by researchers at Dana-Farber Cancer Institute and Brigham and Women’s Hospital.
The study, to be published online on April 1 in the Early Edition of the Proceedings of the National Academy of Sciences (www.pnas.org), tested the effect of a single injection of the antibody MDX-CTLA4 in nine patients who
Research helps physicians understand rare form of ataxia that causes patients to appear ’drunk’ at times
Scientists at Oregon Health & Science University are the first to produce an animal model for episodic ataxia. The condition causes patients to suffer bouts of extreme clumsiness where they have balance, speech and motor difficulties. The research helps scientists better understand this rare and intriguing disorder. It may also help provide valuable information for improved, t
Acetaminophen, the medicine in Tylenol®, clears rapidly and completely from the bloodstream even in doses as high as twice the daily recommended dose, according to new research presented at the 42nd annual meeting of the Society of Toxicology recently in Salt Lake City.
“Our objective was to take what we already knew about the pharmacokinetics of acetaminophen and go a step further,” explained lead investigator Cathy K. Gelotte, PhD, Executive Director, Medical and Regulatory Product Develo
’Hamlet’ algorithm answers the question: ’To buy, or not to buy?’
It’s a classic dilemma for air travelers in today’s world of wildly varying ticket prices – should you purchase now if the rate seems reasonable, or wait for a better deal and take the risk that the price will go up?
Researchers at the University of Washington and the University of Southern California appear to have taken out some of the uncertainty with a new computer program tha
The expensive, energy-intensive process of turning wood into paper costs the pulp and paper industries more than $6 billion a year. Much of that expense involves separating wood’s cellulose from lignin, the glue that binds a tree’s fibers, by using an alkali solution and high temperatures and pressures. Although the lignin so removed is reused as fuel, wood with less lignin and more cellulose would save the industry millions of dollars a year in processing and chemical costs. Research at North Caroli
A team of Carnegie Mellon University and NASA scientists will travel to the Atacama Desert in northern Chile in April to conduct research that will help them develop and deploy a robot and instruments that may someday enable other robots to find life on Mars. The researchers will be using the Atacama, described as the most arid region on Earth, as a Martian analog.
The group is funded with a $3 million, three-year grant from NASA to the university’s Robotics Institute. They are collabo
Ammonia is a problem. All animal cells produce it, but how do they get rid of it? New research by Dr Dirk Weihrauch (University of Illinois at Chicago) to be presented on Wednesday 2 April (session A2.2) suggests that the crab may have evolved a rather novel solution.
For us mammals, the key to getting rid of waste ammonia is to detoxify it into urea in the liver. Marine organisms can employ the rather simpler solution of allowing the toxic ammonia to diffuse into their environment. However,
A new three-drug cocktail used to treat ALS, or Lou Gehrig’s Disease, may increase life span and decrease disease progression according to a study conducted at the Research Institute of the McGill University Health Centre (MUHC). The study, published in today’s issue of Annals of Neurology, is the first to look at this drug combination in a mouse model of ALS. This research was made possible by a partnership led by the Canadian Institutes of Health Research (CIHR), in conjunction with the A
Significantly improved peanut yields have been achieved by researchers at the Hebrew University Faculty of Agricultural, Food and Environmental Sciences in Rehovot.
Through the use of the plant hormone ethylene, the researchers have succeeded in regulating the flowering of the peanut plant, with a resulting four-fold increase in the yield of large peanut pods at harvest time.
The research was carried out by Eliezer Zamski, the Jack Futterman Professor of Agricultural Botan
Researchers have found disturbing new evidence suggesting that environmental exposure to a ubiquitous substance may cause chromosomally abnormal pregnancies. They have learned that low levels of a compound used in the manufacture of common plastic food and beverage containers and baby bottles interfere with cell division in the eggs of female mice. The disruption of cell division can result in an abnormal number of chromosomes in the eggs, a condition known as aneuploidy, which is the leading cause o
