A Phase One Clinical Trial of the PfSPZ Vaccine Shows Hope for the Fight Against Malaria
Research published today in the Science journal suggests that a safe, effective vaccine for malaria may be in sight. Humans get malaria when they're bitten by infected mosquitoes, which, as they bite, transfer parasites that are in their early stages of development. It's these parasites that are in the new vaccine, although they are weakened and in their sporozoite stage. In a study of 57 healthy adults, 12 of the 15 participants who received this vaccine in its highest dosage were protected from the disease. To learn more about the vaccine, check out this podcast interview with the study's lead author on the Science website.
People with malaria feel fever, chills and flu-like symptoms. If these symptoms go untreated, they can become worse and lead to death. The U.S. Centers for Disease Control and Prevention estimates that in 2010, there were 219 million cases of malaria worldwide, resulting in 660,000 fatalities. Most of these people who died – 91 percent of them – had lived in the African region.

American paparazzi is child's play compared to the British national pastime of royalty obsession. And so, not long after the royal baby watch peaked with the clutter of shutters capturing 2-day-old Prince George, the cameras turned back to his new mum, specifically, her royal baby bump.

Meanwhile, readers struck back. Rebuking unfair beauty and body standards placed on women, and new moms, British TV anchor Katy Hill tweeted a picture of her own portly post-partum body and summarily sparked a rallying cry. In calling for praise, not punishment of women's post-baby bodies and a boycott of OK!, Hill elicited thousands of laudatory tweets and retweets in an episode now dubbed babyweight-gate. The magazine owners, in turn, defended their admiration of Mom Middleton. "Like the rest of the world, we were very moved by her radiance as she and William introduced the Prince of Cambridge to the world. We would not dream of being critical of her appearance."

4 Numbers That Could Save Your Life
We learn our phone numbers by first grade and our social security numbers when we're filling out college applications, writes U.S. News blogger Bonnie Taub-Dix. We've memorized our password numbers to unlock our phones, and we even know the numbers representing our favorite sports players' stats. Yet many of us don't know the numbers that could save our lives.
Perhaps the most important aspect of owning your health is knowing your numbers, especially in an emergency situation. You may not always have the same health care provider, but you will most definitely have the same body. If a laboratory test comes back in the normal range, but the results are abnormal for you, the test may go unnoticed by a doctor who sees a high number of patients each day. It's up to you to compare your past and present numbers on your own behalf. You should always save copies of your test results so you can keep detailed files about your state of health.
Here's the 411 on numbers you need to know:
