In the future, may we all have the option to get a double mastectomy. Or, rather, its equivalent for whatever cancer each of us are genetically predisposed to.

Are Tasmanian devils (Sarcophilus harrisii) doomed to extinction in the wild? The infectious cancer known as devil facial tumor disease (DFTD) has killed off as much as 90 percent of the world’s Tasmanian devils since it was first observed in 1996 (up from 70 percent when we last wrote about the species nine months ago). [...]

Research published in Nature Materials this month takes lessons from cooperation in nature, including that observed in insect swarms, to create better targeting methods for cancer therapeutics [1]. "Smart" anticancer drug systems can use mechanisms similar to swarm intelligence to locate sites of disease in the human body. Swarm intelligence arises when swarm behavior, for [...]

May 31, 2011, was a bad day for a society already wary of all sorts of risks from modern technology, a day of celebration for those who champion more concern about those risks, and a day that teaches important lessons about the messy subjective guesswork that goes into trying to make intelligent choices about risk [...]

Over 1.5 million new cancer cases were identified in the United States in 2010, and despite continued advances in cancer treatment, approximately 500,000 cancer-related deaths occurred in the same year (1). For a long time, cancer therapies were a one-size-fits-all, depending on the cancer type. In recent years however, the need has emerged to develop [...]

Everyone knows about cancer. According to the World Health Organization eight million people died of one of the many forms of cancer 2007 and this number is expected to grow to more than 12 million by 2030. However, unlike many other significant diseases, cancer is not confined to a continent or socioeconomic cohort. Also unlike [...]

Curiously, the cancer rate is 10 percent higher in the left breast than in the right. This left-side bias holds true for both men and women and it also applies to the skin cancer melanoma. Researchers Örjan Hallberg of Hallberg Independent Research in Sweden and Ollie Johansson of The Karolinska Institute in Sweden, writing in [...]

Maybe we should all be scared of sugar.

The discovery that stomach ulcers are caused by bacteria is quite recent and was proved fairly conclusively in 1984 when the Australian scientist Barry Marshall drank a petri-dish full of the bacteria Helicobacter pylori and five days later developed serious gastritis, which cleared after antibiotic treatment. As stomach ulcers are quite common, and can be a major [...]

When Angelina Jolie announced last month that she decided to get a prophylactic double mastectomy, she based her decision on the presence of the BRCA1 gene in her body—a gene that was detected via a costly medical test. The Supreme Court today unanimously struck down patents on BRCA1 and BRCA2—two genes linked to hereditary forms [...]

Doctors can’t inject cancer patients with intelligent nanobots programmed to launch surgical counterstrikes against the disease. That didn’t stop a team of medical researchers and software programmers from developing a video game several years ago that helped young patients imagine such an empowering scenario. Based on the success of that project, the team recently launched [...]

Desktop 3-D printers can already pump out a toy trinket, gear set or even parts to make another printer. Medical researchers are also taking advantage of this accelerating technology to expand their options for regenerative medicine. Brian Derby, of the School of Materials at the University of Manchester in England, details the advances and challenges [...]

The mammograms most women receive are decidedly two-dimensional. An x-ray machine takes images of the breast from the sides, and radiologists examine the resulting image to see if it offers up any hits of potentially cancerous irregularities. These tests, however, are far from perfect. Normal calcium deposits and fibrous tissue can align to create a [...]

The more we learn about cancer, heart disease and Alzheimer’s, the more vexingly complex they seem—and the more elusive their cures. Even with cutting-edge imaging technology, biomarker tests and genetic data, we are still far from understanding the multifaceted causes and varied developmental stages of these illnesses. With the advent of powerful computing, better modeling [...]

Evidence for the long-term health benefits of circumcision for newborn boys has been mounting for years. Today the influential group the American Academy of Pediatrics (AAP) declared that the procedure is, indeed, beneficial—and that it should be covered by public and private health insurance plans. The recommendation was published online August 27 in Pediatrics. Previously [...]

This September, cigarette packs in the U.S. will be getting a lot more colorful. And a lot more disturbing. By then, tobacco companies will be required to display one of nine graphic health warnings on each pack, to comply with the Tobacco Control Act of 2009. The U.S. has followed dozens of other countries in [...]

Chemotherapy treatment for cancer is a nasty process. Doctors must try to give patients just enough of the toxic drugs to kill off cancer cells without doing too much harm to the rest of the body’s healthy tissues, a balancing act that, even if successful, can nevertheless cause horrible side effects. But what if you [...]

Breast cancer kills nearly 40,000 women in the U.S. each year—a figure that has been in slow decline in the past two decades, despite (and in part thanks to) improved screening technology and an increase in treatment options. The percentage of women who get breast cancer and survive, however, is a trickier statistic to assess. [...]

More than half a million people died from cancer in the U.S. in 2011. We have many astounding advances in medicine to thank for that number not being higher. But that grim figure could also be a lot lower even without a breakthrough drug for breast or lung cancer. In fact, more than 280,000 of [...]

I was recently in Alaska as an invitee of GoPro cameras in support of a pretty cool science experiment by Project Aether. Briefly, I was there to assist as they launched weather balloons with GoPro cameras attached in order to collect intra-auroral images. After the weather balloons dropped, the GPS tagged cameras were then retrieved, [...]

Sometimes, the list of things to be paranoid about feels endless: BPA in your water bottles, pesticides on your food, prescription drugs in your drinking water, and nanotechnology in your donuts. Luckily, most of these things will not statistically be responsible for your ultimate demise (you can likely credit heart disease and cancer for that). [...]

Most articles in the journal Nature Biotechnology have titles like “Selective Enrichment of Newly Synthesized Proteins for Quantitative Secretome Analysis.” They don’t usually contain sentences like this: “The special-purpose vehicle’s capital structure, priority of payments and various coverage tests and credit enhancements are collectively known as the ‘cash flow waterfall’—a reference to the manner in [...]

In his new book “To Save Everything, Click Here: The Folly of Technological Solutionism”, the philosopher of technology Evgeny Morozov develops the concept of “technological solutionism”, the tendency to define problems primarily or purely based on whether or not a certain technology can address them. This is a concerning trend since it foreshadows a future [...]

This seems to have become unofficial volcano week, here at ScienceBlogs. If you haven’t been following the coverage of the Eyjafjallaj
