Climate-warming CO₂ emissions will hit a record high in 2019
Despite countries adopting renewable power sources and coal use falling slightly, oil and gas use are pushing global carbon dioxide emissions to record heights.
- Space
How brightly the moon glows is a mystery, but maybe not for long
The best estimates for the moon’s brightness are still somewhat unsure. A new experiment is trying to fix that.
- Earth
Critics say an EPA rule may restrict science used for public health regulations
Editors of six major scientific journals argue that a rule proposed by the U.S. EPA may keep key data from factoring into environmental regulations.
- Archaeology
An AI found a hidden Nazca Line in Peru showing a humanoid figure
An artificial intelligence program designed to go through massive datasets for hints of ancient geoglyphs called Nazca Lines has discovered a new one.
- Tech
A tiny switch could redirect light between computer chips in mere nanoseconds
Microscopic switches that ferry information using light, not electric current, could help create better, faster electronics.
- Physics
Trapping atoms in a laser beam offers a new way to measure gravity
A new type of experiment to measure the strength of Earth’s gravity uses atoms suspended in light rather than free-falling atoms.
- Tech
Here’s what it will take to adapt the power grid to higher wildfire risks
Better sensing tech on power lines and reliance on more local power sources could help avoid vast power outages like those in California in October.
- Chemistry
American whiskeys leave unique ‘webs’ when evaporated
If you don’t have a sophisticated palate, it turns out you can distinguish among bourbons with a microscope.
- Space
Rules guarding other planets from contamination may be too strict
Voluntary international guidelines for visiting the moon, Mars and other places — and for bringing stuff back to Earth — are overly cautious, scientists say.
- Space
The solar system may have a new smallest dwarf planet: Hygiea
New images reveal Hygiea is round, a final criterion for promoting the wee world from asteroid to dwarf planet status.
- Space
Strontium is the first heavy element detected from a neutron star merger
The discovery of strontium created inside a neutron star smashup gives the clearest picture yet of what goes on inside this chaotic environment.
- Planetary Science
Astronomers have spotted a new type of storm on Saturn
In 2018, telescopes on Earth and in space identified a never-before-seen kind of storm activity on the ringed planet.
