Human technology such as cell phones and broadcast towers constantly radiate radio waves ROOMand astronomers estimate that this telltale sign of humanity has been included 75 nearby star systems, signaling to any alert alien civilization that Earth hosts a technologically advanced species. And while scientists have been listening to the incessant radio chatter from our … Read more
Summary: Mental maps in the brain are activated when we think about sequences of experiences, even without physical movement. In an animal study, they found that the entorhinal cortex contains a cognitive map of experiences, which is activated during mental simulation. This is the first study to show the cellular basis of mental simulation in … Read more

Astronomers expect a “new star” to appear in the night sky anytime between now and September in a celestial event that has been years in the making, according to NASA. “It’s a once-in-a-lifetime event that will create a lot of young astronomers out there, giving young people a cosmic event they can observe for themselves, … Read more
Teflon objects (orange cylinders) were placed in a waveguide with a rectangular cross section. Then, an electromagnetic signal (blue wavefront) was injected from the right to extract information about the metallic cuboid shown in gray. By measuring the wave field in the area shown in red, researchers can show how information is generated and transported … Read more
HUSTON – Hello, from your fellow Houstonian! I know it’s already hot in Texas as we prepare for the intense summer and humid heat we are blessed with every year. Apparently it’s getting hotter as we get older — or is it just me? Anyway, I wasn’t much of a beach girl growing up, but … Read more
A rare burst of light from a dead star is likely to be visible to humans in earth this summer in a fleeting but potentially gloomy celestial display that scientists are calling “a once-in-a-lifetime event.” The technical term for the impending cosmic explosion is nova, which occurs when a white dwarf suddenly and often spectacularly … Read more
Following one dirty anchorage on the International Space Station last week, Boeing managed to send a pair of NASA astronauts to the orbiting laboratory. The stressful Starliner saga continues as the crew capsule developed more leaks in its service module. NASA is currently evaluating its ability to return the pair to Earth. The first Sonos … Read more
