Saudi-led airstrikes in Yemen have been called war crimes. Many relied on U.S. support.

A joint Washington Post analysis reveals for the first time that the United States supported the majority of air force squadrons involved in the Saudi coalition’s years-old air campaign in Yemen.

'Whisper networks' thrive when women lose faith in formal systems of reporting sexual harassment

Whisper networks—informal channels that women use to warn others about sexual harassment, abuse or assault—take root because formal reporting systems can re-traumatize people who have been harmed. That's what I found while conducting research on this topic for my dissertation.

Superconductivity and ferroelectricity found in the same 2D material

When it comes to two-dimensional materials, it's best to expect the unexpected. Writing in Nature, researchers at Columbia find evidence that two competing phenomena—superconductivity and ferroelectricity—can occur within the same material. "This is the first time that a tunable switch between ferroelectricity and superconductivity has ever been seen," said corresponding author Daniel Rhodes. "We don't fully understand it just yet, but it's definitely there."

Enabling nanoscale thermoelectrics with a novel organometallic molecular junction

The Seebeck effect is a thermoelectric phenomenon by which a voltage or current is generated when a temperature difference exists across a conductor. This effect is the basis of established and emerging thermoelectric applications alike, such as heat-to-electricity energy harvesters, sensing devices, and temperature control.

Innovation strengthens electron-triggered light emissions for quantum-based computational and communications systems

The way electrons interact with photons of light is a vital part of many modern technologies, from lasers to solar panels to LEDs. But the interaction is inherently weak because of a major mismatch in scale: the wavelength of visible light is about 1,000 times larger than an electron, so the way the two things affect each other is limited by that disparity.

Apollo 7 astronaut Walter Cunningham dead at 90

Walter Cunningham, the last surviving astronaut from the first successful crewed space mission in NASA's Apollo program, died Tuesday in Houston. He was 90. NASA confirmed Cunningham’s death in a statement but did not include its cause.

There Will Never Be Another One Like Ken Block

It's been roughly 24 hours since the world lost Ken Block in a snowmobile accident in Utah, and at this point there really isn't anything else to say
