Semiconductor quantum transistor opens the door for photon-based computing

Semiconductor quantum transistor opens the door for photon-based computing

Transistors are tiny switches that form the bedrock of modern computing; billions of them route electrical signals around inside a smartphone, for instance. Quantum computers...
Einstein's theory of general relativity proven right again

Einstein’s theory of general relativity proven right again

In a novel test of Einstein's theory of general relativity, an international group of astronomers has demonstrated that the theory holds up, even for...
Einstein gets it right again Even phenomenally dense neutron stars fall like a feather

Einstein gets it right again: Even phenomenally dense neutron stars fall like a feather

Einstein’s understanding of gravity, as outlined in his general theory of relativity, predicts that all objects fall at the same rate, regardless of their...

New discovery bolsters Einstein’s theory about how heat moves through solids

A discovery by scientists at the Department of Energy's Oak Ridge National Laboratory supports a century-old theory by Albert Einstein that explains how heat...
Scientists discover another useful property of graphene

Scientists discover another useful property of graphene

Gently compressed stacks of graphene form sharp crinkles that carry an electric charge, which could be useful in nanoscale self-assembly and other applications. Researchers from...
Is there really dark matter New galactic test helps answer the question

Is there really dark matter? New galactic test helps answer the question

A new study found a way to determine whether the mysterious 'star putty' really exists Researchers used sophisticated computer simulations to devise a test that...
New MRI scanner could revolutionize brain tumor diagnosis and treatment

New MRI scanner could revolutionize brain tumor diagnosis and treatment

When Reem Itani learned she had a brain tumor, she was distraught—but not for the obvious reason. Her endocrinologist told her the tumor was "MRI-negative,"...
Astronomers discover hydrogen laser emission from planetary nebula for the first time

Astronomers discover hydrogen laser emission from planetary nebula for the first time

Astronomical masers (the radio wavelength analogs of lasers) were first identified in space over fifty years ago and have since been seen in many...
Scientists create continuously emitting microlasers with nanoparticle-coated beads

Scientists create continuously emitting microlasers with nanoparticle-coated beads

Researchers have found a way to convert nanoparticle-coated microscopic beads into lasers smaller than red blood cells. These microlasers, which convert infrared light into light...
