Before geoengineering to mitigate climate change, researchers must consider some fundamental chemistry

It's a tempting thought: With climate change so difficult to manage and nations unwilling to take decisive action, what if we could mitigate its effects by setting up a kind of chemical umbrella—a layer of sulfuric acid ...

Researchers control multiple wavelengths of light from a single source

KAIST researchers have synthesized a collection of nanoparticles, known as carbon dots, capable of emitting multiple wavelengths of light from a single particle. Additionally, the team discovered that the dispersion of the ...

Dynamic charge density fluctuations pervading the phase diagram of a Cu-based high-Tc superconductor

Charge density fluctuations are observed in all families of high-critical temperature (Tc) superconducting cuprates. Although constantly found in the underdoped region of the phase diagram at relatively low temperatures, ...

Visualizing how radiation bombardment boosts superconductivity

Sometimes a little damage can do a lot of good—at least in the case of iron-based high-temperature superconductors. Bombarding these materials with high-energy heavy ions introduces nanometer-scale damage tracks that can ...

Confirmed: Stellar behemoth self-destructs in a Type IIb supernova

Our Sun may seem pretty impressive: 330,000 times as massive as Earth, it accounts for 99.86 percent of the Solar System's total mass; it generates about 400 trillion trillion watts of power per second; and it has a surface ...

Axions Not Cause of Unexpected Observation

Scientists from France have shown that hypothetical axion-like particles cannot explain some unexpected observations in an Italian experiment carried out last year. Ruling out axions will likely subdue some of the renewed ...

What is dark energy? Inside our accelerating, expanding universe

Some 13.8 billion years ago, the universe began with a rapid expansion we call the Big Bang. After this initial expansion, which lasted a fraction of a second, gravity started to slow the universe down. But the cosmos wouldn't ...
