The moon is thought to have been created in a violent collision, and a new simulation of the event could answer questions that have puzzled astrophysicists Space 11 March 2022 By Alex Wilkins Artwork of the collision that gave rise to the moon MARK GARLICK/SCIENCE PHOTO LIBRARY A computer simulation that traces the moon’s formation … Read more

A New Simulation of Mars’s Core Could Explain How It Lost Its Magnetic Field

by

Mars is a parched planet ruled by global dust storms. It’s also a frigid world, where night-time winter temperatures fall to minus 140 C (minus 220 F) at the poles. But it wasn’t always a dry, barren, freezing, inhospitable wasteland. It used to be a warm, wet, almost inviting place, where liquid water flowed across … Read more

Behold, The Most Accurate Virtual Simulation of Our Universe to Date

by

In the Cosmic Calendar, which maps the chronology of the Universe across a single Earth year, modern humans don’t appear until the very last minute of December 31. Everything we understand about the evolution of the Universe, we’ve had to piece together. We simply haven’t been around for pretty much any of the 13.7 billion-year … Read more

There’s a Cancer Treatment That Gives People ‘Night Vision’. Here’s How

by

Among all the different types of cancer treatment, photodynamic therapy – where light is used to destroy malignant cells – might have one of the strangest side effects: Patients are often better able to see in the dark.   Last year, researchers finally figured out why this happens: Rhodopsin, a light-sensitive protein in the retinas in our eyes, interacts with … Read more
