From wearable electronics to microscopic sensors to telemedicine, new advances like graphene and supercapacitors are bringing "impossible" electronics to life.
Individual space telescopes, like Hubble and JWST, revolutionized our knowledge of the Universe. What if we had an array of them, instead?
They are expected to be cheaper to build and even more reliable than today’s nuclear plants.
Why are the rest masses of fundamental particles related like this? When it comes to the nature of matter in the Universe, the Standard Model describes the known elementary particles perfectly […]
Women have made incredible gains into STEM fields, but they continue to face gender biases in the workplace.
If you think ‘particles are matter’ and ‘antiparticles are antimatter,’ think again. In this Universe, there are certain rules that have never been observed to be broken. Some of these […]
Every observation out into deep space is also a look back in time. Whenever you observe an object, you aren’t viewing it in its present state. When one of Jupiter’s moons […]
Neutrons can be stable when bound into an atomic nucleus, but free neutrons decay away in mere minutes. So how are neutron stars stable?
The way to understand the earliest moments of creation is to recreate those conditions and study them. Why would we stop now?
We value human life in a way that assumes we possess a sacred something not found in beings like lambs, turkeys, or mosquitoes.
Until recently, we were only able to view Venus's surface with radar or by landing on the planet. It was believed that Venus's surface was entirely obscured by clouds; NASA's Parker Solar Probe proved otherwise.
We can describe what we see happening, but we don’t understand why. Despite our vast cosmic knowledge, enormous unknowns remain. The quantum fluctuations inherent to space, stretched across the Universe […]
Puerto Rico's iconic telescope facilitated important scientific discoveries while inspiring young scientists and the public imagination.
Even with all the recent impacts we've seen, it might be more "foe" than "friend" to us.
“It doesn’t erase what happened to you. It just changes the impact it has on your life.”
For the cosmos, it’s all too easy being green. Stars come in a wide variety of colors, but never green. Stars form in a wide variety of sizes, colors and masses, […]
There are an estimated two trillion galaxies within the observable Universe. Most are already unreachable, and the situation only gets worse.
Every power source involves trade-offs. Given the challenges of increasing demand and climate change, what is the future of energy?
Scientists at the San Diego Zoo are on a mission to resurrect the extinct northern white rhino.
Forget these scientific myths to better understand your brain and yourself.
After years of analysis, the Event Horizon Telescope team has finally revealed what the Milky Way's central black hole looks like.
Infrared, visible, and ultraviolet combine to show us Jupiter’s features as never before. The largest planet in our Solar System, Jupiter, is our own ‘failed star.’ The best evidence-based classification scheme […]
A new control system, demonstrated using MIT’s robotic mini cheetah, enables four-legged robots to jump across uneven terrain in real-time.
Archaeologists discover a cave painting of a wild pig that is now the world's oldest dated work of representational art.
Cryptocurrency “news” is dominated by enthusiasts and haters. Surely, an intellectual discussion can be had.
Previously, only the brightest and most active galaxies could pierce the obscuring wall of cosmic dust. At last, normal galaxies break through.
A few years ago, the first dark matter-free galaxies were announced, and then immediately disputed. Now, there are too many to ignore.
