Acting Editor in Chief Elizabeth Quill discusses science's complexities.

Features

Green catalysts illustration
Researchers are designing catalysts to move chemical reactions without using precious metals, or at least using less of them.
cancer cells
There may be ways to block tumors from adapting and outrunning the body’s defenses.

News

rocky outcrop on Mauritius
Zircon crystals from a long-gone continent called Mauritia may have resurfaced during volcanic eruptions on the island of Mauritius in the Indian Ocean.
illustration of sun, Earth and moon
Oxygen atoms originating from the upper atmosphere periodically bombard the moon’s surface, researchers propose.
castor beans
Mice treated with a blend of antibodies survived even when treated days after exposure to ricin.
Hercules beetles
Genetic evidence alone may overestimate numbers of species, researchers warn.
sea turtle
Climate change overheating sea turtle nestlings may be a greater danger than temperature-induced shifts in their sex ratios.
person looking sad
Those who stay mentally healthy from childhood to middle age are exceptions to the rule.
Banded iron
The Great Oxidation Event that enabled the eventual evolution of complex life began 100 million years earlier than once thought, new dating of South African rock suggests.
Abell 2744
Gravitational lensing has revealed extremely faint galaxies in the early universe, suggesting these tiny galaxies were responsible for cosmic reionization.
East Asian hunter-gatherer skull
Ancient hunter-gatherers in East Asia are remarkably similar, genetically, to modern people living in the area. Unlike what happened in Western Europe, this region might not have seen waves of farmers take over.
Iron Age gold spheres
Wealthy woman’s 2,600-year-old grave highlights Central Europe’s early Iron Age links to Mediterranean societies.
Mars’ volcano-filled Tharsis region
The magma fueling a Martian volcanic system remained largely unchanged for billions of years, analysis of a newfound meteorite suggests.
merging black hole simulation
High rate of spin could indicate that black holes formed from previous mergers of black holes.
frog
Here’s what puts the grip in a frog’s high-speed strike: quick-change saliva and a tongue softer than a marshmallow.
NIST Center for Neutron Research
Updated experiments hope to resolve neutron lifetime discrepancy.
Chinese researchers used a CRISPR/Cas 9 gene editor to make cows more resistant to tuberculosis.
bat bot
Unlike other aerial robots that use whirling rotor blades to fly, the Bat Bot relies on soft, silicone-based wings to glide, swoop and turn.
gamma-ray blazars
Intensely bright galaxies are the farthest blazars ever detected in gamma rays.
five quasars
Quasar observations add to discrepancy in measurements of the universe’s expansion speed.
LSD in brain protein
The newly discovered structure of a human serotonin receptor linked to LSD could reveal why the drug’s hallucinogenic effects last so long.
gold ion collisions
Collisions of gold ions create a fluid with more vorticity than any other known.
capuchin monkey
Spillback of Zika virus into monkeys may complicate eradication efforts.
Chandra telescope
Excess of X-rays could indicate decaying sterile neutrinos.
a tasty salad
A new device uses cold plasma to kill foodborne pathogens.
Ebola virus
Scientists are developing highly specific antibodies to detect Ebola sooner.
researcher working with mercury
Increased runoff to the ocean due to climate change could raise neurotoxic mercury in coastal sea life by disrupting the base of the food web.
clouds of gas
Four clouds of gas near the galactic center have roughly the right mass to be young stars, possibly with planets.
hydra vulgaris
Regenerating pond animals called hydras inherit structural patterns from their original forms, researchers find.

Notebook

deuterostome fossil
Dozens of tiny fossils discovered in 540-million-year-old limestone represent the earliest known deuterostomes, a diverse group of animals that includes humans and sea cucumbers.
Birgus latro
Coconut crabs use their surprisingly powerful claw for more than cracking coconuts.
stained image of fish head
New study reveals anatomical secrets of mysterious deep ocean fish.
talking to a smartphone
Early versions of computer speech recognition relied on word sounds. Now, they add pattern recognition and a lot of statistics.
2011 Japan tsunami
A tsunami’s ferocious force could be taken down a few notches with a pair of counter waves.

Reviews & Previews

Enrico Fermi and Richard Garwin
New biographies highlight Enrico Fermi’s and Richard Garwin’s contributions to science and society.

Letters to the Editor

Quantum spookiness, shifting landmasses and more in reader feedback.
