Contagion is a thriller about a virus that rapidly spreads to become a global epidemic. There aren’t enough coffins. Gangs roam neighborhoods like ours because police have abandoned their posts, fearful of exposure. Garbage fills the streets because sanitation workers are dying. As scientists work feverishly to understand the virus and develop a vaccine, public panic unravels the fabric of civil society, fueled by terror and rattled by false claims of a homeopathic cure promoted by a charismatic charlatan.
The movie has grossed $76 million worldwide since it opened on September 9th. It has all the elements a successful movie needs: a just-believable dystopian vision of the future, flawed good guys, an evil schemer, suspense, heroic action…the works.
And while it’s an action-thriller first and foremost, you don’t have to concentrate hard to notice that it also shows:
- Why the Federal government is necessary: its authority to communicate, negotiate and work with other nations to solve a global problem; its ability to exert authority across state lines and to marshal resources immediately to protect its citizens from peril with no expectation of profit.
- How scientific research is iterative and complicated, not bumbling or malicious. Research is conducted by scientists—normal people with normal lives—who are Read more »

Women who smoke begin menopause a year earlier than nonsmokers, researchers concluded, adding that earlier menopause is associated with osteoporosis and heart disease.
Researchers conducted a meta-analysis of the available data about smoking and menopause, finding 11 studies comprising about 50,000 women, using age 50 as a threshold for early or late age at natural menopause (ANM). Results appeared in Menopause.
In five studies, participants were classified as Read more »

Hallelujah. At last there is an actual, published paper (full text behind subscription firewall, unfortunately) objectively documenting not only a lack of longevity benefit for several commonly consumed dietary supplements, but a numerical association indicating potential harm. Finally!
Investigators looked at nearly 39,000 women (in scientific terms: a lot) over 19 years of follow up (in scientific terms: a long time) and found increased risk of death in women who took supplemental iron (strongest association), copper, zinc, magnesium, Vitamin B6, and multi-vitamins.
Wow.
If nothing else, that should at least give one pause when considering whether or not to take supplements at all, especially in the demographic studied (the “older female”). But are they overstating their case? Scare-mongering? Not at all. In fact, the following caution was explicitly added by the researchers: Read more »

Oropharyngeal cancers caused by the human papillomavirus (HPV) are on the rise in the United States since 1984, as changes in sexual habits further the virus’ spread. But the focus of the HPV vaccine will remain on preventing genital warts and cervical cancer.
Reuters reported one clinician’s opinion that throat cancer linked to HPV will become the dominant cause of the disease, ahead of tobacco use.
To study the issue, researchers determined HPV-positive status among 271 of all 5,755 oropharyngeal cancers collected by the three population-based cancer registries in Hawaii, Iowa and Los Angeles from the Surveillance, Epidemiology, and End Results (SEER) program from 1984 to 2004. Prevalence trends across four calendar periods were estimated by using logistic regression. The study appeared online Oct. 3 in the Journal of Clinical Oncology.

Cell cultures form the basis of many types of lab research, however growing these cell cultures has always been a time-consuming, laborious job that is largely done by hand.
That is about to change, with the Fraunhofer Institute and Max Planck Institute having developed a machine that completely automates the process of cultivating cells.
From the press release:
The device consists of an array of modules: One of these is a robot that transports the vessels containing the cell cultures, known as multititer plates, from one place to the next. Dr. Albrecht Brandenburg, group manager at IPM describes another module: Read more »
