How to build the perfect sandcastle—according to science

Whether we prefer water sports or relaxing with a good book, the humble sandcastle is often a seaside must. But what's the secret to building a majestic sandcastle that will withstand the tide of time? Luckily, there's a scientific formula for that.

The exciting future of light energy

In a world of growing energy needs, and a global imperative to halt carbon emissions, a tiny 'quasiparticle' called an exciton could provide the answer to our problems.

New approach improves ability to predict metals' reactions with water

The wide reach of corrosion, a multitrillion-dollar global problem, may someday be narrowed considerably thanks to a new, better approach to predict how metals react with water.

Making wires of polymers chains

Researchers have modeled a new route to molecular wires suitable for use in miniature electronics.

Shaking Schrödinger's cat

Frequent measurement of a quantum system's state can either speed or delay its collapse, effects called the quantum Zeno and quantum anti-Zeno effect. But so too can "quasimeasurements" that only poke the system and garner no information about its state.

New study opens the door to solid-state devices that use excited electrons

For the first time, engineers and scientists at Caltech have been able to directly observe the ultrafast motion of electrons immediately after they are excited with a laser—and found that these electrons diffuse into their surroundings much faster and farther than previously expected.

Scientists develop synthetic diamond-based detectors for CERN

A research team of Tomsk Polytechnic University is participating in the upgrade of the Large Hadron Collider (LHC) at the European Center for Nuclear Research (CERN). The TPU scientists were assigned to analyze operating detectors and to develop more reliable next-generation diamond detectors to record the collisions of elementary particles accelerated to velocities close to light speed, which occur every 28 nanoseconds.

Interplay of light and matter: A 'perfect' attosecond experiment

Novel experiments using ultrafast pulses are currently revolutionizing laser physics research. They deliver unprecedented insights into matter – into the structure and dynamics of electrons in atoms, molecules and in condensed phases. Using what is known as an attosecond experiment, physicists have managed to completely measure and describe the quantum-mechanical wave function of an ionized electron.

Ring, Ring: 'Earth? It's space calling, on the quantum line'

Scientists report the successful transmission of entangled photons between suborbital space and Earth.

Georgia Students to Speak with NASA Astronaut on the International Space Station

Students at the Fayette County Public Library in Fayetteville, Georgia, will speak with a NASA astronaut living and working aboard the International Space Station at 11:45 a.m. EDT on Monday, June 19. The 20-minute, Earth-to-space call will air live on NASA Television and the agency’s website.
