  • Undergraduate Adventures with the Thermally Responsive Nanoparticles

    Last October I attended the National Women in Physics Conference at Lincoln Nebraska. For an undergraduate women in Physics this is an amazing conference that offers a great opportunity to network with other young physicists and learn about the research going on around the country. While at the conference, I met many great people who [...]

    Molecules to Medicine: Plan B: The Tradition of Politics at the FDA

    In my last post, I focused on flaws in the medical device approval process. The Union of Concerned Scientists’ “FDA at a Crossroads” meeting also covered problems with drug approval. This is perhaps no better illustrated than by the disappointing decision by Secretary of Health Kathleen Sebelius’ to deny the emergency contraceptive, Plan B, over-the-counter [...]

    Tsunami Debris and North America: Is the Tail Wagging the Dog?

    Recent weeks have seen a spate of news articles (three examples here, here, and here) claiming that wreckage from the March 2011 Japanese tsunami has started arriving on the west coast of North America.

    Conflicts and Cooperation in Conservation: Adventures in Researching the Pygmy Hippopotamus on Tiwai Island, Sierra Leone

    Our vehicle pulled into the village late one rainy night. Dozens of my new neighbors, Sierra Leone’s Mende people, emerged from their thatch-roof houses, looking cross at being woken up and not exactly welcoming. We unloaded some of my gear underneath the dripping eaves, and as I tried to find something dry to wear, I [...]

    If It Looks Like a Compliment, and Sounds Like a Compliment…Is It Really a Compliment?

    Two weeks ago I was at Science Online 2012, the annual conference for science bloggers and writers in Raleigh, NC. While there, I attended the session on Blogging Science While Female (a more detailed summary of the session can be found here).

    A Wildlife Vet, a Pigeon, a Groundbreaking Discovery

    One of the reasons I love my job as a wildlife veterinarian so much is the variety of my days. No two days are the same; each is filled with different animals with different problems, and I love the anticipation of what my day may bring. I never know what kind of animal will come [...]

    The Joys of Quantum Entanglement

    Quantum entanglement is such a mainstay of modern physics that it is worth reflecting on how long it took to emerge. What began as a perceptive but vague insight by Albert Einstein languished for decades before becoming a branch of experimental physics and, increasingly, modern technology. Einstein’s two most memorable phrases perfectly capture the weirdness [...]

    Eating off the Floor: How Clean Living Is Bad for You

    Ten steps to a healthier life and more wealth through embracing the bacteria around you. Book titles are difficult to choose. In theory, a perfect title is concise, compelling, enticing and, oh by the way, accurately conveys some aspect of the book’s contents.

A routine prelaunch test turned fatal when a fire ripped through the spacecraft’s crew cabin killing all three astronauts.

    The Disappearing Actinides, and Other Frustrations from the Bottom Row of the Periodic Table of the Elements

    I bought three copies of Sam Kean’s The Disappearing Spoon: And Other True Tales of Madness, Love and the History of the World from the Periodic Table of the Elements. I left the first one in the seat-back pocket of Delta flight 188 from Beijing to Detroit. The second one is sandwiched between ROCK and [...]
