Challenges Facing the CDC’s Research Laboratories as They Review Lab Safety

Following several recent incidents of possible exposure to dangerous diseases, the Centers for Disease Control (CDC) announced last week that it has halted operations at its bioterrorism rapid-response lab and an influenza lab and imposed a moratorium on any biological material leaving numerous other CDC labs. National Research Council reports discuss operational safety and security and measures for encouraging a culture of responsible conduct when working with select agents. These titles can provide insight into the challenges facing these laboratories. All are free to download.

Responsible Research with Biological Select Agents and Toxins

The effort to understand and combat infectious diseases has, during the centuries, produced many key advances in science and medicine–including the development of vaccines, drugs, and other treatments. A subset of this research is conducted with agents that, like anthrax, not only pose a severe threat to the health of humans, plants, and animals but can also be used for ill-intended purposes. Such agents have been listed by the government as biological select agents and toxins. The 2001 …

Our cybersecurity expert gives his take on the charges of cyberattack by the Chinese army

The recent charges of hacking into US corporate targets against five members of the Chinese army has brought the issue of cybersecurity into the headlines. We asked Herb Lin, one of the editors of our new report on the intersection of cybersecurity and public policy, for his thoughts:

“As discussed in At the Nexus Of Cybersecurity and Policy, this story brings to the fore differences in how the United States and virtually every other nation view intelligence gathering. The United States draws sharp distinctions between intelligence for national security purposes and for economic purposes, whereas China (and most other nations in the world) do not. The difference in values is not likely to be reconciled any time soon. It also turns out that access was gained through the use of relatively unsophisticated penetration techniques, thus underscoring the point that simple defensive techniques can have significant value.” — Herb Lin, Chief Scientist at the Computer Science and Telecommunications Board

Watch this video of Herb running down six things to know about cybersecurity and public policy, and some of the things we can do to start tackling the problems:

NAP.edu is (and always was) unaffected by the Heartbleed bug

heartbleedYou may have heard a lot of worrying things about the Heartbleed web security vulnerability, and to be sure, it’s worrying. But nap.edu is totally unaffected by Heartbleed and was never in danger (slightly more technical version: we were not running the affected version of Open SSL), so you can rest assured that your login and payment information on NAP are and always have been completely secure with us. You don’t have to change your MyNAP password, though it’s generally a good practice to change out all of your passwords regularly and make sure that you have a unique password for each website you log onto.

While we’re on the subject, we thought you might like to take a break from hearing about Heartbleed to read more about cybersecurity from some of the expert research that the Academies have done on the topic. We picked out some of the notable titles and put them in our Cybersecurity Collection.

Start of a New Trend? Preschool Obesity Rate Declines

Great news! According to a new report, the obesity rate among 2–5-year old children has dropped 43 percent during the past decade, the first significant decline in an epidemic that often leads to lifelong struggles with weight and higher risks for cancer, heart disease and stroke. The not-so-great news—we still face challenges to reduce the incidence of obesity in the United States, as a third of adults and 17 percent of youth are obese.

Reports about obesity from The Institute of Medicine provide guidance for health professionals, policymakers, schools, and concerned citizens to continue their efforts to improve the health of Americans. We’ve listed some of them below, and have more in our special collection of obesity titles. All are free to download.

Does Climate Change Influence Drought?

After three consecutive years of below-normal rainfall, California faces its most severe drought emergency in decades. This image from NOAA of snow in the Sierra Mountains illustrates how the historic lack of rain has created a water shortfall.

drought_california_map

NOAA image

Governor Jerry Brown has called for Californians to reduce water use by 20 percent voluntarily, and mandatory rationing could be ordered soon so that homes, businesses and farms don’t run dry over the summer. California’s drought has far-reaching consequences that include dramatically less water for farms and communities and increased fires in both urban and rural areas.

Does climate change influence drought? What should be done to both provide water and protect ecosystems? Reports from the National Research Council explore these questions. Our resources discuss the science of climate change, consider climate change impacts at community and national levels, and recommend areas for further research. We also have reports that discuss options to provide water by improving water management and promoting water reuse. All are free to download.

Changes to NAP.edu: Citation Manager, Sharing, Embed Widget

We’re always looking for ways that we can improve the experience of browsing, reading, and researching on NAP.edu, so it’s great to hear from frequent visitors about how they use the site and changes they’d like to see. Recently, we took some feedback and moved a few things around on the catalog page (the primary page for each book on NAP.edu).

share-cite-embed-changes

First up are the share tools, which allow you to share to social networks and other places around the web with a single click. They used to be at the very bottom of the page, but we were hearing that they were a little hard to find there, so they will now appear along the very right hand side of the page when you’re viewing the site on a desktop computer and as a grey “Share” bar at the bottom of the page when you’re looking at a tablet or smartphone.

Another move that we made were the links to embed a book into your website or to email the page to a friend. That also used to be in that hard-to-find share bar at the bottom of each page, but will now be at the top of the right column in each page.

Last but definitely not least is the citations, where you can quickly copy and paste a citation to a book or download the citation in BibTeX, EndNote, or RefMan formats. The link to this used to be in the upper right column, but its now lost its “manager” title (it’s a lateral move) and has been moved it into the bottom of the “Overview” tab of each book.

If you want to see these changes in action, check them out on one of our newer releases. And if you have any comments on the changes or other suggestions on ways we could improve the website, feel free to send us feedback about what you’d like to see.
