The connection of everything to time bending: from the speeding fly to Einstein

Time is not a simple thing: in physics, the rate of clocks depends on speed and gravity, while in the brain, the sense of time is influenced by attention, memory, and emotional state. A journey through flies, astronauts, and neuroscience shows where time really is

After a century, scientists discover a hidden rule governing cosmic rays

A long-standing cosmic mystery is beginning to yield new clues as researchers discover a strikingly consistent pattern in the behavior of high-energy particles moving through the universe.

The asteroid the size of four Everests that changed the course of life on Earth

It turns out that these giant meteorites actually had a positive effect on life compared to the later extinction-causing meteorites

MRI scans can provide information about the iron balance in the brain to help monitor and diagnose various diseases, in a non-invasive manner

This new measurement method, developed by the doctoral student Shir Filo and Prof. Metzer, will allow the extraction of precise biological values ​​on the brain, so that it will be possible to derive from an MRI test similar indices to those obtained from a test

Surprising presence of sulfur in the soil of the South Pole of the Moon by the Indian robotic vehicle Paragain in the Chandrayaan-3 mission

The vehicle discovered a wide variety of heavy elements, but this is the first evidence of the presence of sulfur * The rover will tour the south pole of the moon for two weeks and look for signs of water ice
