How much does a cloud weigh

Imagine 300 midsize cars floating above your head -- that's how much your average fluffy cloud weighs. So why doesn't it come crashing down...

Scientists create single-nanowire spectrometers to replace Newton’s glass prism

Scientists have designed an ultra-miniaturized device that could directly image single cells without the need for a microscope or make chemical fingerprint analysis possible...

Giant impacts can dramatically drop the internal pressures in planets, says study

A new study from Caltech shows that giant impacts can dramatically lower the internal pressure of planets, a finding that could significantly change the...

Scientists mash quantum and gravity and find time, but not as we know it

Quantum events can unfold in a 'new time order'. A University of Queensland-led international team of researchers say they have discovered "a new kind of...

Nanoparticles could someday give humans built-in night vision

Movies featuring heroes with superpowers, such as flight, X-ray vision or extraordinary strength, are all the rage. But while these popular characters are mere flights...

Scientists find unusual behaviors in colloidal crystals

Argonne scientists have used small particles as electron equivalents to create metallic behavior in colloidal systems primarily composed of larger particles. These small particles...

Nano-thermometer can now take a single cell’s temperature

How do you know a cell has a fever? Take its temperature. That’s now possible thanks to research by Rice University scientists who used the...

Physicists create world’s smallest engine

The engine is approximately ten billion times smaller than that of a car, and could one day help recycle waste heat and thus improve...

Scientists discover another giant planet in the Beta Pictoris system

Astronomers have discovered a second giant planet in orbit around β Pictoris, a star that is relatively young (23 million years old) and close...

Scientists create a heat shield just 10 atoms thick to protect electronics

The heatshields would protect people and temperature-sensitive components and make future electronic gadgets even more compact. Excess heat given off by smartphones, laptops and other...
