    Why Cancer Drugs May Work Better While You Sleep

    <em>Time</em> reports on the recent finding by Weizmann scientists that our bodies fight cancer better during the day, meaning that nighttime might be much better for administering cancer drugs. This ""happy accident"" is an example of how basic research can shed light on important issues.

    On the Probiotic Trail

    The probiotics research of Dr. Naama Geva-Zatorsky helped her win a prestigious UNESCO-L'Oreal international fellowship. But that's just the beginning of what promises to be a long career, as ""there are 10 times more bacteria than human cells in the body,"" influencing everything from health to weight to depression.

    You're Probably Not Mostly Microbes

    <em>The Atlantic</em> reports that new findings by Dr. Ron Milo overturn long-held ideas about us and our microbes. The generally accepted microbe-to-person ratio was 10:1, meaning that we would be exponentially outnumbered by our bacteria. But Dr. Milo and his team have found that the proportion is more like 1:1 – and that just using the restroom can change the balance.

    Of Mice and Men: Researchers Find Differences in Cell Development

    The <em>Los Angeles Times</em> reports on Dr. Jacob Hanna's discovery of a method for creating human primordial germ cells. Critically, the work also revealed that, in experiments, mice aren't necessarily the best substitutes for humans; in fact, the human cell results were significantly different from those with mice.

    Israeli Biologists Rebuke Facebook, Apple for Suggesting Female Workers Freeze Eggs

    Much has been made about companies offering to pay for women employees to freeze their eggs. But is this even realistic or healthy? As <em>The Jerusalem Post</em> reports, two of the Weizmann Institute's leading scientists, Profs. Michal Neeman and Nava Dekel, have ""strong"" objections to the offer, saying that while it is laudable to encourage women to succeed, they shouldn't have to pay such a high price.
