Here's how scientists developed a once-a-day pill that reduced the risk of sexually transmitted HIV transmission by 99%, a breakthrough that transformed the course of the HIV/AIDS epidemic.
Watch the DART Spacecraft Smash into an Asteroid
Could we deflect an asteroid barreling toward Earth? NASA’s DART mission--the first test of its kind--showed that we may be able to knock an asteroid off its path, if we ever need to.
How Storm Surges Work—and Why They’re So Deadly
The deadliest part of a hurricane isn’t the wind–it’s water. Here’s what causes a storm surge, and which regions are most at risk.
How Computer Algorithms Make Predictions
These computer programs use artificial intelligence to look for patterns in data without human instruction.
Computers v. Crime Preview
In police departments and courts across the country, artificial intelligence is being used to help decide who is policed, who gets bail, how offenders should be sentenced, and who gets parole. But is it actually making our law enforcement and court systems fairer and more just? This timely investigation digs into the hidden biases, privacy risks, and design flaws of this controversial technology.

Ending HIV in America Preview
Almost 40 years after the discovery of HIV, could we be on the verge of ending the AIDS epidemic in America? How did scientists tackle one of the most elusive deadly viruses to ever infect humans? Can innovative drugs bring new infections to zero?
How Seaweed May Help Revive Our Oceans
In some parts of the ocean, like in the Gulf of Mexico, there is so little oxygen in the water that marine life is actually suffocating. Could kelp help, or is it mostly hype?
The Hidden Cause of Traffic Jams—and How to Solve Them
Some traffic jams seem to happen out of nowhere—it’s not rush hour, no construction, no accidents. These are called phantom traffic jams, generally caused by drivers tapping the brakes on and off. Could autonomous vehicles eliminate these traffic jams, and make our roads safer? Some researchers think so.
The False Promise of Cloning Your Pet
Departed pets can now live on through reproductive cloning. But many owners have been surprised to find that genetics aren’t everything—Fluffy the second turns out to be an animal all its own.
Why Distant Galaxies Look Red
The James Webb Space Telescope, a project 30 years in the making, launched in December 2021 and arrived at its destination point in January. The telescope will be able to see further into the infrared part of the spectrum than Hubble, and further back in time.
How Scientists Created JWST's First Test Image
A month after its launch, the next step for the James Webb Space Telescope was to align all 18 of its mirrors. Aligning the 18 mirrors of the James Webb Space Telescope took extreme precision and allowed it to take its first image—a star amongst many galaxies.
NASA Reacts to the James Webb Space Telescope Images
This team of space scientists, visual developers and science writers have been working together since early June processing the images of celestial objects, and the spectra of the atmosphere of an exoplanet, for release to the public, so the world can see what Webb can do. They are the only team members who’ve had the privilege of seeing the images.
