brain map
By combining different types of data, researchers have drawn a new detailed map of the human brain.
ketogenic meal
Mice’s response to diet varies with their genes.
Kepler telescope
Kepler space telescope adds another 104 planets to its growing census of worlds in our galaxy.
eclipse
With one year to go, researchers are making plans for studying both the sun and Earth during the August 2017 total solar eclipse.
Staphylococcus lugdunensis and MRSA
A bacterium isolated from the nose produces a new antibiotic active against resistant pathogens.
person vaping
New study homes in on a primary source of toxic vaping compounds: the thermal breakdown of solvents used to dissolve flavorings in e-liquids. And older, dirtier e-cigs generate more of these toxicants, study shows.
cloned sheep
Cloning doesn’t cause premature aging in sheep.
yeast, bacteria and a plant
Many genes are interchangeable between yeast, bacteria, plants and humans.
wolf lichen
Yeasts newly discovered in common lichens challenge more than a century of thinking about what defines the lichen symbiosis.

Land bridges may have once allowed dinosaurs and other animals to travel between North America and Europe around 150 million years ago, a researcher proposes.
Alzheimer’s plaques in human brain
A new study found that antibiotics hit Alzheimer’s plaques in the brains of mice.
electrons illustration
Electrons usually repel each other, but new research shows pairs of electrons can be attracted due to their repulsion from other electrons.
propofol
Brains regions that are synchronized when awake stop communicating as monkeys drift off.
Mosquito mutations
Gene drives’ fatal flaw could be a bonus.
Florida adds 10 new cases of locally acquired Zika infection, prompting the CDC to issue travel warning for pregnant women. Mosquitoes in Miami may be resistant to insecticides.
Jupiter's Great Red Spot
High temperatures over Jupiter’s Great Red Spot suggest that storms pump heat into the atmosphere and warm the entire planet.
Carniolan honeybee
Male honeybees produce less living sperm if raised on pollen tainted with neonicotinoids, tests show.

A newly discovered oil-producing organ inside the swordfish’s head gives the animal slick skin to swim faster.
Gualicho
A new dinosaur species discovered in Patagonia has the runty forearms of a Tyrannosaurus rex, but is not closely related to the gigantic predator.
<em>P. prehensicauda</em>
Blood and bones turn naturally green in island lizards. Their evolutionary history still needs explaining.
Camptotheca acuminate
Researchers looked to traditional Chinese medicine for cancer treatment clues 50 years ago. Today, synthetic versions treat a variety of cancers.
magnetic flares
Magnetic fields within the sun rise up no faster than about 500 kilometers per hour, suggesting that the movement of gas is responsible for bringing these fields to the sun’s surface.
