When a droplet of water falls on a hot pan, it dances across the surface, skimming on a thin layer of steam like a tiny hovercraft; this is known as the Leidenfrost effect. But now, researchers know what happens when a hot droplet falls on a cool surface. When a droplet of water falls on a…
Researchers in Sweden report a green alternative to reduce reliance on mining graphite, the raw source behind the “wonder material” graphene. In the journal Small, researchers at KTH Royal Institute of Technology say they have developed a reproducible and scalable method for producing graphene oxide (GO) nanosheets from commercial carbon fibers, marking a breakthrough in…
A team of scientists have developed a method to illuminate the dynamic behavior of nanoparticles, which are foundational components in the creation of pharmaceuticals, electronics, and industrial and energy-conversion materials. The advance, reported in the journal Science, combines artificial intelligence with electron microscopy to render visuals of how these tiny bits of matter respond to…
Since the financial crisis of 2008, the stock market has seen a remarkable migration of investor money away from active management and toward passive, or index, funds. As a result, the “Big Three” asset managers—BlackRock, Vanguard and State Street—have swiftly ballooned into behemoths. Taken together, they constitute the largest shareholder in more than 40% of…
Developed at NASA JPL, the science instrument gives researchers a more detailed picture of high-temperature surfaces, such as land scorched by wildfire, than previous infrared instruments.

In this NASA/ESA Hubble Space Telescope image, Hubble once again lifts the veil on a famous—and frequently photographed—supernova remnant: the Veil Nebula. The remnant of a star roughly 20 times as massive as the sun that exploded about 10,000 years ago, the Veil Nebula is situated about 2,400 light-years away in the constellation Cygnus. Hubble…
If you start with a two-dimensional ribbon and make it narrower and narrower, when does it stop being a ribbon and start being a one-dimensional line? Scientists from Utrecht University and the University of Twente made one-atom-thick ultrathin nanoribbons consisting of germanium atoms. If you start with a two-dimensional ribbon and make it narrower and narrower,…
Recently, paleontologists Dr. John-Paul Zonneveld, Dr. Sarah Naone, and Dr. Brooks Britt described the discovery and classification of four new ichnotaxa (fossilized trace taxa) from the Eocene mudflat successions of Utah.

Light was long considered to be a wave, exhibiting the phenomenon of interference in which ripples like those in water waves are generated under specific interactions. Light also bends around corners, resulting in fringing effects, which is termed diffraction. The energy of light is associated with its intensity and is proportional to the square of…
