Newly Described Algae Species Toughens Up Corals to Endure Warming Oceans
Healthy unbleached (brown) Pocillopora corals from the Eastern Pacific possess a thermally tolerant symbiont species of algae (Symbiodinium glynnii), while unhealthy or dead bleached (white) corals possess a more sensitive symbiont.

Malaria parasites sense and adapt to their host’s nutritional status
Malaria parasites replicate into many daughter cells inside red blood cells. The red blood cells eventually burst (cell on the left), allowing the parasites to infect new red blood cells. In hosts with reduced calorie intake, fewer daughter cells are produced per round of replication, decreasing the severity of the infection and potentially allowing the host to survive longer.

Flexible flagella fight flow: Bacteria change a liquid’s properties and escape entrapment

Genes, Ozone, and Autism: Increased risk for autism when genetic variation and air pollution meet
Genes, Environment, and the Risk for Autism: Environment factors (ozone) can interact with genetic factors (copy number variation) to produce an even higher risk for autism than expected by adding the two risk factors, one that might not be found by studying the factors independently.

New way to weigh a white dwarf: Use Hubble Space Telescope
This drawing shows the observed versus actual positions of a distant star whose light is distorted by the curvature of space around a heavy star that is between the distant star and the observer. In this case, the observer is the Hubble Space Telescope. Credits: NASA, ESA, and K. Sahu (STScI)

New planet found to be hotter than most stars
A newly discovered Jupiter-like world is so hot that even its nights are like the flame of a welding torch. Planet KELT-9b is hotter than most stars. With a day-side temperature of more than 7,800 degrees Fahrenheit (4,600 Kelvin), it is only about 2,000 degrees Fahrenheit (1,200 Kelvin) cooler than our own sun. Credit: R. Hurt (IPAC), NASA/JPL-Caltech
