Thirty years after bismuth emitting a proton was detected and measured in 1996, an international collaboration led by researchers at the University of Jyväskylä, Finland, detected and measured the half-life of the heaviest proton emitter 188At (astatine) isotope, which decayed by emitting a proton. While isotopes often undergo radioactive decay by emitting alpha, beta, and … Read more

Research has shown that micro- and nano-plastics are present at the top of the tallest mountains, at the bottom of the deepest trenches, and … Read more
On April 14, 2025, Blue Origin launched six women – Aisha Bowe, Amanda Nguyễn, Gayle King, Katy Perry, Kerianne Flynn, and Lauren Sánchez – on a suborbital journey to the edge of space. The headlines called it a historic moment for women in space. But as a tourism educator, I paused – not because I … Read more
My telescope, set up for astrophotography in my light-polluted San Diego backyard, was pointed at a galaxy unfathomably far from Earth. My wife, Cristina, walked up just as the first space photo streamed to my tablet. It sparkled on the screen in front of us. “That’s the Pinwheel galaxy,” I said. The name is derived … Read more

The ring-shaped track that scientists used to study tiny particles called muons at the Fermi National Accelerator Laboratory near Chicago, 2023. | Photo Credit: AP Final results from a long-running U.S.-based experiment announced Tuesday show a tiny particle continues to act strangely — but that’s still good news for the laws of physics as we … Read more
The Andromeda galaxy, imaged here by a Nikon Z7 camera in 2023, is about 2.5 million lightyears away and moving towards the Milky Way galaxy at around 110 km/s. | Photo Credit: Lviatour (CC BY-SA) It turns out that looming collision between our Milky Way and Andromeda galaxies might not happen after all. Astronomers reported … Read more

Their retina has more rod cells, which aid scotopic vision or vision under dark conditions, than cone cells, which aid photopic vision or vision under … Read more
To live a cozy life on the earth, a temperature of around 25° to 30° C is ideal. But during a heat wave, where temperatures can cross 40° C, the consequences can be deadly. Humans and most complex multicellular organisms are not built to tolerate such heat. That doesn’t mean no living thing can, however. … Read more
