Carbon nanotubes twice as strong as once thought

Carbon nanotubes — those tiny particles poised to revolutionize electronics, medicine, and other areas — are much bigger in the strength department than anyone ever thought, scientists are reporting. New studies on the strength of these submicroscopic cylinders of carbon indicate that on an ounce-for-ounce basis they are at least 117 times stronger than steel and 30 times stronger than Kevlar, the material used in bulletproof vests and other products.

New investigational compound targets pancreatic cancer cells

SCOTTSDALE, Ariz. (Sept. 14, 2010) – A new investigational drug designed to penetrate and attack pancreatic cancer cells has been administered to a patient for the first time ever at the Virginia G. Piper Cancer Center at Scottsdale Healthcare.

ASG-5ME is a potent, targeted compound designed to selectively kill cancer cells, says Daniel Von Hoff, MD, a principal investigator in the Phase I clinical trial. Pancreatic cancer is a fast-growing and difficult to treat form of cancer, and is the fourth leading cause of cancer death in the United States.

Death at home less distressing for cancer patients and families

BOSTON—Cancer patients who die in the hospital or an intensive care unit have worse quality of life at the end-of-life, compared to patients who die at home with hospice services, and their caregivers are at higher risk for developing psychiatric illnesses during bereavement, according to a study by researchers at Dana-Farber Cancer Institute.

A new understanding of 31 years of Chesapeake Bay nutrient trends

Reducing the delivery of nutrients to the Chesapeake Bay is one of the most important components of restoration efforts to achieve a healthy Bay ecosystem. The USGS has developed a new method for tracking the progress toward reducing nitrogen and phosphorus delivery from the watershed to the Bay.

Eating broccoli could guard against arthritis

Scientists at the University of East Anglia (UEA) are launching a groundbreaking new project to investigate the benefits of broccoli in the fight against osteoarthritis.

Initial laboratory research at UEA has found that a compound in broccoli called sulforaphane blocks the enzymes that cause joint destruction in osteoarthritis – the most common form of arthritis.

Broccoli has previously been associated with reduced cancer risk but this is the first major study into its effects on joint health.

Home's electrical wiring acts as antenna to receive low-power sensor data

If these walls had ears, they might tell a homeowner some interesting things. Like when water is dripping into an attic crawl space, or where an open window is letting hot air escape during winter.

Urgent need for prostate cancer screening amongst Dutch men

Arnhem, 15 September 2010 – A recent TNS NIPO survey, on behalf of the Dutch Association of Urology (NVU) and the European Association of Urology (EAU), showed that almost four out of 10 Dutch men of 50 years and older suffer, or have suffered, from urinary complaints. The same number of men also said in the same survey they are worried that they may have prostate cancer.

Battery behavior at the nanoscale gets a look

OAK RIDGE, Tenn., Sept. 14, 2010 -- As industries and consumers increasingly seek improved battery power sources, cutting-edge microscopy performed at the Department of Energy's Oak Ridge National Laboratory is providing an unprecedented perspective on how lithium-ion batteries function.

From chemical engineering to the catwalk

Seamless fabric that can be sprayed on to skin and other surfaces to make clothes, medical bandages and even upholstery will be demonstrated this Thursday, in advance of the Science in Style spray-on fashion show next week at Imperial College London.

Solar cells in wrapping-paper form

Washington, D.C. (September 14, 2010) -- Driven by rapid global industrialization, finite fossil fuel reserves, and the high cost of many alternative energy options, meeting the world's energy challenge may demand novel solutions. One potential solution has its roots in the ubiquitous industrial invention: the factory.

Farm management choice can benefit fungi key to healthy ecosystems

Farming practices have a significant impact on the diversity of beneficial microbial fungi known to play important roles in crop productivity, soil recovery and maintenance of healthy ecosystems, according to new research published today (14 September 2010) in the journal Environmental Microbiology. The conclusions could have important implications for the way humans manage the agricultural landscape and tackle food security issues.

Biofuel from inedible plant material easier to produce following enzyme discovery

Researchers funded by the Biotechnology and Biological Sciences Research Council(BBSRC) have discovered key plant enzymes that normally make the energy stored in wood, straw, and other non-edible parts of plants difficult to extract. The findings, published today in Proceedings of the National Academy of Sciences, can be used to improve the viability of sustainable biofuels that do not adversely affect the food chain.

Male maturity shaped by early nutrition

EVANSTON, Ill. --- It seems the old nature versus nurture debate can't be won. But a new Northwestern University study of men in the Philippines makes a strong case for nurture's role in male to female differences -- suggesting that rapid weight gain in the first six months of life predicts earlier puberty for boys.
