Mysterious space objects that transmit radio signals every 54 minutes

Astronomers have discovered a peculiar radio signal originating from deep space that eludes current scientific understanding. Designated ASKAP J1935+2148, the signal repeats every 53.8 minutes, making it the longest period ever recorded for such a phenomenon. Published in the magazine Astronomy of Naturethe discovery, made using the Australian Square Kilometer Array Pathfinder (ASKAP) radio telescope, … Read more

Odysseus private moon plane reveals what Earth technosigns aliens can

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

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

How the brain maps memories without movement

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

A once in a lifetime cosmic explosion is likely this summer NASA says

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
