Liquid

Ordinarily, if you want liquid to flow in only one direction through a pipe, that pipe has to have a flap-type valve – which could fail. Now, scientists have created a new type of more robust one-way-flow pipe, which was inspired by shark intestines.

Harvard engineers have created a strange new “metafluid” – a liquid that can be programmed to change properties, like its compressibility, transparency, viscosity and even whether it’s Newtonian or not.

Contrary to elementary school science class, it turns out that heat may not be necessary to make water evaporate. Scientists at MIT have made the surprising discovery that light alone can evaporate water, and is even more efficient at it than heat.

The Earth’s inner core is incredibly tricky to study, since it’s buried beneath thousands of miles of rock. New seismic studies suggest that it’s not just a solid ball of iron, as has been assumed, but might have pockets of liquid iron throughout.

New evidence has emerged in the debate about whether there’s liquid water on Mars. In a study led by the University of Cambridge, scientists examined the topology of Martian ice sheets and found signatures that match subglacial lakes here on Earth.

Carbon capture could be an important tool to fight climate change. Researchers have now developed a new compound that can reportedly remove carbon dioxide from ambient air with 99 percent efficiency and at least twice as fast as existing systems.

In 2018 astronomers announced the discovery of lakes of liquid water on Mars at the south pole. Sadly, a trio of new papers refutes the claim, with new experiments suggesting that the “water” signal was more likely produced by frozen clay instead.

A team of researchers has found that aerosol particles can contain up to three liquid phases at once. The strange discovery has implications for air quality and climate models, since they could change the level of sunlight reflected or absorbed.

If you've ever wondered what would happen to wine aged for a year in space then wonder no more. The first ever tasting of "space wine" has been conducted, with one expert describing it as “more evolved” than its similarly aged earthbound counterpart.

Mundane as it may seem, glass is a surprisingly mysterious material. Now scientists at the University of Konstanz have identified a new state of matter called liquid glass, which has some unusual properties.

Ordinarily, if you want to make a 3D-printed liquid-filled object, you have to inject the liquid after the object has been printed. A new process, however, allows such items to be printed in one step – and it could have some valuable applications.

The closest thing we have to magnetic liquids are ferrofluids. But now, Berkeley Lab has managed to create the first permanently magnetic liquids, which could open up new avenues for electronics and robotics.
