The risks of low-speed impacts with liquids

When a solid object hits a liquid, the impact produces shock waves: a process that has long occupied engineers due to its implications for design of hydraulic systems or motors. KAUST researchers now show that impacts at ...

Chlorate-rich soil may help us find liquid water on Mars

If liquid water exists on the surface of Mars, it is most likely in the form of a briny mixture with magnesium chlorate salts, according to new experiments based on discoveries previously made by NASA's Phoenix and Viking ...

Scientists lay the groundwork for a reliable marijuana breathalyzer

Marijuana is now legal for recreational or medicinal use in at least 28 states and the District of Columbia. But driving under the influence of marijuana is illegal no matter which state you're in. To enforce the law, authorities ...

Open-source approach provides faster, better solubility predictions

The solubility of any given substance—the measure of how well the substance dissolves into another substance referred to as the solvent—depends on basic properties like temperature and pressure, as well as the chemical ...

A field research network to address looming grain failures

Across the United States, record quantities of corn and soybeans have been harvested in recent years. However, according to a BioScience article by David Gustafson of the International Life Sciences Institute Research Foundation ...

Five properties of physics that affect your gas mileage

Physics is inescapable. It's everywhere, making your Frisbees fly, your toilets flush and your pasta water boil at a lower temperature at altitude. We've harnessed these forces, along with chemistry and engineering, to build ...
