    Lizards might snooze like humans do. Sleeping lizards appear to share distinctive brain activity patterns with sleeping birds and mammals, researchers report. If true, the results suggest that human sleep patterns evolved by around 300 million years ago in a common ancestor of birds, mammals and reptiles.

    Blocking gut reactions could help defend against heart disease. Intestinal microbes break down the nutrient choline, abundant in meat and eggs, into a compound that leads to hardening of the arteries. A drug candidate that prevents the microbes from making this conversion in mice can reduce both the amount of this compound and the extent of artery damage.

    New experimental vaccines use viral DNA and proteins to help animals' immune systems fight the virus that causes Middle East respiratory syndrome. The vaccines stimulate the production of antibody proteins that latch onto and disable the MERS virus, researchers report July 28 in Nature Communications. When attacking MERS viruses, antibodies target a virus protein called the Spike glycoprotein. The scientists designed vaccines containing either the viral DNA with the genetic blueprint for making this protein, or a section of the protein itself.

    Corals are in hot water and may soon lose their ability to handle the heat. In Australia’s Great Barrier Reef, most past bouts of warming allowed many corals to adjust their physiology and avoid serious damage. But as waters warm even more, corals may run out of wiggle room, researchers report.
