Researchers at Rensselaer Polytechnic Institute have developed a novel carbon-nanotube-based material that chokes vibration and may have applications for both large and small devices.
In the January 9, 2004, advance online edition of Nature Materials, the researchers describe the new material and demonstrate its usefulness as a filler to enhance traditional vibration-reduction materials.
Conducted by Nikhil Koratkar and colleagues at Rensselaer, the research arose from Ko
In the course of 2003-2004, the Research Council of Norway organised a foresight analysis for Norwegian aquaculture. All in all, more than 70 people took part in a systematic dialogue about the future. The information presented here represents a very brief summary of an exhaustive report containing detailed analyses from the Foresight project: Aquaculture 2020: Transcending the Barriers – As long as…

New health economic data published in the European Journal of Hospital Pharmacy outline the cost benefits of the non-steroidal anti-androgen bicalutamide 150mg for the treatment of locally advanced prostate cancer. By delaying disease progression in patients with locally advanced prostate cancer, bicalutamide 150mg reduces the additional healthcare costs associated with treating advanced disease.
The paper by Dr Heather Payne, Middlesex Hospital UCL, London states that bicalutam
An Internet-based system to help revive flagging areas hit by the decline of traditional heavy industry, such as steel and mining, has been developed with the help of 850,000 euros from the EU’s Framework Programme.
VISION was launched to create an Internet-based system to promote rapid industrial reconversion. This is a major issue for large parts of Europe where the loss of traditional industries left areas of high unemployment and social deprivation, despite many being populated
CreationOnline customer interactions exceed 2 million milestone in December / Additional PROPRIS reference data service to be launched for data vendors Customer usage of Clearstream’s new Corporate Action Service for the efficient management of corporate action activities has exceeded initial expectations: Since its launch on December 6 last year the service has attracted over 290 financial institutions and a total of 50,141 user interactions on CreationOnline. It has driven ov
Teenage mothers often focus on instrumental behaviour rather than displaying affection towards infants
Mothers who are more mature tend to display more affection towards their infants whereas teenage mothers often focus on instrumental behaviour – fixing their infant’s clothes or their soother – finds a new study of maternal behaviour.
“While the study is still preliminary, this finding was very surprising,” says Katherine Krpan, lead author of the study, conducted as
Combination of behavioral enrichment and antioxidant supplementation in diet reveal clear-cut benefits
A new study of beagles led by researchers at the University of Toronto at Scarborough underscores the importance of using a combination of diet and behaviour therapies to curb the progressive decline in the ability to learn that occurs with advanced aging. “We were really surprised just how clear-cut the benefit is of using a combined therapy,” says lead investigator and psycho
Modern proverbs to illustrate great truths about public health principles
It’s time to add to our store of proverbs with new phrases that teach us how to be healthier, says a University of Toronto researcher.
In a paper published in the Dec. 2004 issue of the Journal of Epidemiology and Community Health, Bernard Choi, a professor in the Department of Public Health Sciences, suggests that we need to create new science-based proverbs that reflect current information about
New understanding of the dynamic interplay between genes and environment, made possible by technologies arising from the Human Genome Project, helps support the individualization of medicine and makes focusing on racial or ethnic group differences in disease less relevant, say Penn State researchers.
“Technology has given us the ability to make a much more comprehensive picture of health outcomes,” says Dr. Keith Whitfield, associate professor of biobehavioral health. “We now see,
Mayo Clinic researchers studying endometrial cancer have found that patients at risk for relapse based on identified risk factors had a 46 percent probability of experiencing recurrence within five years despite treatment with state-of-the-art therapy.
The study’s findings are important for women deemed at risk because they might need additional treatment, which physicians should consider in their treatment plans for their patients, says Karl Podratz, M.D., Ph.D., the study
Grapefruit juice can be deadly for people on certain medications, nurse researchers remind doctors, nurses, and everyone who takes medicine and enjoys grapefruit juice, in a paper in the American Journal of Nursing, a journal of the American Nurses Association.
Amy Karch, R.N., M.S., of the School of Nursing at the University of Rochester Medical Center reported on a man from a northern climate who moved to Florida for the winter – one of tens of thousands of “snowbirds” who head so
Astronomers announced Jan. 10 that they have a lead in the case of the missing disks. The report was presented by UCLA graduate student and Ph.D. candidate Peter Plavchan; his adviser, Michael Jura; and Sarah Lipscy, now at Ball Aerospace, to the American Astronomical Society meeting in San Diego. This lead may account for the missing evidence of red dwarfs forming planetary systems.
The evidence
Red dwarfs (or M Dwarfs) are stars like our Sun in many respects but smaller,
An unprecedented flash observed by the space shuttle Columbia crew in 2003 over the Indian Ocean may be a new type of transient luminous event, like lightning sprites, but one that is not necessarily caused by a thunderstorm. The discharge was observed less than two weeks before the shuttle was lost during its Earth reentry.
The authors describe the discharge as a Transient Ionospheric Glow Emission in Red, or TIGER, event. It was recorded by a video camera in the near-infrare
In two articles, published in Circulation, researchers from the University of Pennsylvania School of Medicine provide further evidence for the role of cyclooxygenases (COX) in heart-disease risk. In one, a statistical meta-analysis of two placebo-controlled trials, the COX-2 inhibitor Bextra elevated the combined incidence of heart attack and stroke three-fold in coronary artery bypass graft (CABG) surgery patients. In the second, the investigators found that a fat produced by COX-1 speeds ha
The latest findings in cancer vaccine development suggest that cancer vaccines may have two modes of action; specific immunization and non-specific activation of immune cells paralyzed by the tumor.
The human immune system fights cancer partly through the production of many populations of specialized immune cells called cytolytic T cells (CTL). Each CTL population recognizes a different, specific marker, an ’antigen’, on the cancer cell surface. Cancer vaccines are d
A new study by researchers at Memorial Sloan-Kettering Cancer Center and The Johns Hopkins University provides new insight into how tumor cells can become resistant to anti-cancer therapy.
The scientists observed that a protein called P-glycoprotein (P-gp), which causes resistance to chemotherapy in many tumor types, is able to physically “jump” or transfer between tumor cells and retain its functional properties, protecting otherwise sensitive cells from the effects of anti-ca
