Electromagnetic water cloak eliminates drag and wake

Engineers have developed a realistic proposition for creating a water cloak that moves water around an object by applying forces on dissolved ions through a carefully designed electromagnetic field.

Two holograms in one surface

Engineers have developed a way to encode more than one hologram in a single surface with no loss of resolution.

New Space Policy Directive Calls for Human Expansion Across Solar System

President Donald Trump is sending astronauts back to the Moon.

A diamond as the steppingstone to new materials, using plasma physics technology

Physicists have taken the first step in a five-year effort to create novel compounds that surpass diamonds in heat resistance and nearly rival them in hardness. Reserachers investigated how the addition of boron, while making a diamond film via plasma vapor deposition, changed properties of the diamond material.

Midwife and signpost for photons

Targeted creation and control of photons: This should succeed thanks to a new design for optical antennas.

Graphene spin transport takes a step forward towards applications

Researchers have predicted and demonstrated a giant spin anisotropy in graphene, paving the way for new spintronic logic devices.

NASA Provides Coverage of Today’s Space Policy Directive Signing

NASA Television and the agency’s website will provide live coverage of the Space Policy Directive – 1 signing ceremony at the White House at 3 p.m. EST today.

Basic element for quantum computer -- stable quantum gate -- created

Physicists create a stable quantum gate as a basic element for the quantum computer.

Physicists excited by discovery of new form of matter, excitonium

Excitonium has a team of researchers ... well... excited! They have demonstrated the existence of an enigmatic new form of matter, which has perplexed scientists since it was first theorized almost 50 years ago.

Blackbody radiation from a warm object attracts polarizable objects

You might think that a hot object pushes atoms and molecules away due to radiation pressure. But a research team showed that for a polarizable atom, the opposite occurs: the hot object attracts it. Using an atom interferometer, they found the attraction was 20 times stronger than the gravitational attraction between a tungsten object and a cesium atom. Though negligible in most situations, next-generation gravitational wave experiments may have to take this into account.
