Researchers are describing a long-awaited advance toward applying the marvels of nanotechnology in the battle against cancer. They have developed the first hollow gold nanospheres — smaller than the finest flecks of dust — that search out and "cook" cancer cells. The cancer-destroying nanospheres show particular promise as a minimally invasive future treatment for malignant melanoma, the most serious form of skin cancer, the researchers say. Melanoma now causes more than 8,000 deaths annually in the United States alone and is on the increase globally.
Researchers in Canada are reporting that proteins found in a common garden pea show promise as a natural food additive or new dietary supplement for fighting high blood pressure and chronic kidney disease (CKD). Those potentially life-threatening conditions affect millions of people worldwide.
The study was presented at the ACS meeting in Salt Lake City and says that peas can relieve symptoms of CKD naturally.
Peas long have been recognized as nutritional superstars, with healthful amounts of protein, dietary fiber, and vitamins wrapped in a low-fat, cholesterol-free package. The new research focuses on the yellow garden pea, a mainstay pea variety enjoyed as a veggie side-dish and used as an ingredient in dozens of recipes around the world.
Carbohydrates are tough molecules to build because of their complicated, branched structure. So instead of trying to build carbohydrates from scratch, scientists today use molecules isolated from nature, a painstaking process that could take months.
Speaking at the ACS meeting in Salt Lake City, Peter H. Seeberger, Ph.D., described development of an automated carbohydrate synthesizer, a device that builds these intricate molecules in a few hours — rather than the months or years required with existing technology.

There is a conversation about evolution that I’m apparently doomed to replay over and over with various family members, friends and acquaintances.
I tell a friend that the evidence for evolution is overwhelming - everywhere in biology you find the signature of evolution; in every little bizzare, unexpected nook of biology you find unmistakeable evidence that all life is related, descended from common ancestors that lived long ago and took forms that were very different from what we observe in today’s organisms. We swim in a deluge of evidence, and I’m baffled that anyone can disregard the pervasive stamp of evolution in nature.
Whoever I’m having this conversation with is equally baffled. How can I look around at the unparalleled complexity of nature, at the amazing adaptations possessed by millions of species, and think that this all came about through an unintelligent process?
Leading statistician Professor David Spiegelhalter claims today that the number of murders in London last year was not out of the ordinary and followed a predictable pattern. Spiegelhalter's report, published today in Significance, the magazine of the Royal Statistical Society, argues that shocking headline numbers are not as surprising as one might think.
Violence in London attracts headlines. After four people were murdered in separate incidents in London on July 10th, 2008, BBC correspondent Andy Tighe said "To have four fatal stabbings in one day could be a statistical freak." But could it? On July 28th thelondonpaper had the front-page headline: "London's murder count reaches 90". But Professor Spiegelhalter states that this number was predictable.
Two guest writers on Olivia Judson's blog offer
an interesting idea for spending stimulus money on research:
Instead of simply funding more grants, we suggest using some of the windfall to provide an opportunity for fresh college graduates to pursue two years of research in the nation’s service while the job market is bottoming out. Call it “Research for America.” Our proposal would put young Americans to work and support science — without setting off a later bust cycle in research support, as previous funding booms have done.
People have always been fascinated by bats, but mostly in their erratic flying and their bizarre habit of sleeping upside down. But landing with bad eyesight is not so easy either and a research team is the first to document the landing approaches of three species of bats — two that live in caves and one that roosts in trees. What they found was that bats landing are like people parallel parking their cars; we recognize it, but they don't all do it the same way.
Evolutionary theorist Alastair Clarke says eight patterns are the basis of all the humor that has ever been imagined or expressed, regardless of civilization, culture or personal taste.
That's right, if you thought you heard that Seinfeld joke before, it's because it is part of your collective unconscious.
Clarke has stated before that humor is based on the 'surprise' recognition of patterns but now he has gone further and identified the precise nature of the patterns involved, addressing the deceptively simple unit and context relationships at their foundation. His research goes on to demonstrate the universality of the theory by showing how these few basic patterns are recognized in more than a hundred different types of humor.
