It's cool to be small. Scientists at the National Institute of Standards and Technology (NIST) have miniaturized the optical components required to cool atoms down to a few thousandths of a degree above absolute zero, the first step in employing them on microchips to drive a new generation of super-accurate atomic clocks, enable navigation without GPS, and simulate quantum systems.

When drought caused devastating crop losses in Malawi in 2015-2016, farmers in the southeastern African nation did not initially fear for the worst: the government had purchased insurance for such a calamity. But millions of farmers remained unpaid for months because the insurer's model failed to detect the extent of the losses, and a subsequent model audit moved slowly. Quicker payments would...

Delivering a minor electric shock into a stream to reveal any fish lurking nearby may be the gold standard for detecting fish populations, but it's not much fun for the trout.

Among the materials known as perovskites, one of the most exciting is a material that can convert sunlight to electricity as efficiently as today's commercial silicon solar cells and has the potential for being much cheaper and easier to manufacture.

It is no secret that over the last few decades, humans have changed nature at an ever-increasing rate. A growing collection of research covers the many ways this is impacting our quality of life, from air quality to nutrition and income. To better understand how which areas are most at risk, scientists have combed through volumes of literature to present global trends in the relationship between...

Microscopy is the workhorse of contemporary life science research, enabling morphological and chemical inspection of living tissue with ever-increasing spatial and temporal resolution. Even though modern microscopes are genuine marvels of engineering, minute deviations from ideal imaging conditions will still lead to optical aberrations that rapidly degrade imaging quality. A mismatch between the...
