2019 Nobel Prize in Physics: Evolution of the universe and discovery of exoplanet orbiting solar-type star


This year's Nobel Prize in Physics is being awarded "for contributions to our understanding of the evolution of the universe and Earth's place in the cosmos," with one half to James Peebles "for theoretical discoveries in physical cosmology" and the other half jointly to Michel Mayor and Didier Queloz "for the discovery of an exoplanet orbiting a solar-type star."

Costs of natural disasters are increasing at the high end

While the economic cost of natural disasters has not increased much on average, averages can be deceptive. The costs of major disasters like hurricanes Katrina, Maria and Dorian or the massive tornado swarms in the Midwest have increased to a disproportionately larger extent than those of lesser events, and these major disasters have become far more expensive, according to an international team of researchers.

Picoscience and a plethora of new materials

The revolutionary tech discoveries of the next few decades may come from new materials so small they make nanomaterials look like lumpy behemoths. These materials will be designed and refined at the picometer scale, which is a thousand times smaller than a nanometer. A new study moves picoscience in a new direction: taking elements from the periodic table and tinkering with them at the subatomic level to tease out new materials.

Next-generation single-photon source for quantum information science

Researchers have built what they believe is 'the world's most efficient single-photon source.' And they are still improving it. With planned upgrades, the apparatus could generate upwards of 30 photons at unprecedented efficiencies. Sources of that caliber are precisely what's needed for optical quantum information applications.

This is how a 'fuzzy' universe may have looked

Scientists have found that the early universe, and the very first galaxies, would have looked very different depending on the nature of dark matter. For the first time, the team has simulated what early galaxy formation would have looked like if dark matter were ''fuzzy,'' rather than cold or warm.

Exoplanets to medical tests: Tiny frequency devices open up new applications

Accurately measuring frequencies of light is required for timekeeping and many science experiments and technologies. Frequency combs, invented in 2000, are used to complete these measurements. However, most of them are large and cumbersome. In 2009, researchers developed a way to make much smaller combs, but they came with their own challenges. New research finds that a novel way of generating frequency combs could address these challenges, leading to compact frequency combs with untold applications.
