Anyone who has ever carried a tray full of pint glasses without getting their feet wet knows that such a feat is hard work, but perhaps our sympathies should go out to the baristas in coffee shops instead. New research has concluded that carrying coffee without spilling is harder than beer since the foam on the surface of beer dampens sloshing.Credit: Julius Schorzman via Wikimedia CommonsA team of physicists at Princeton and NYU Polytechnic School of Engineering set up an experiment […]

Choi, Contributor(Inside Science) -- An ancient meteorite has now yielded the first physical evidence that intense magnetic fields played a major role in the birth of our solar system.Shortly after the sun formed about 4.6 billion years ago, a rotating disk of gas and dust that surrounded the newborn star coalesced into the planets that children now memorize. Astronomers peering at young distant stars find […]
Two Massachusetts teams develop slick coatings to keep ketchup, other items from sticking to surfaces.

Both teams have founded companies to exploit applications of their patented technology.The developments promise […]
A simulated wormhole. Credit: Corvin Zahn licensed under cc-by-sa/2.0/de/Let's talk about wormholes. I won't be spoiling anything to say that the plot of Christopher Nolan's latest film, Interstellar, hinges on the existence of a large wormhole allowing intrepid astronauts to travel through in search of new worlds to colonize.In the film, the wormhole is basically just a deus ex machina — a simple plot device to get the main characters out into deep space. Nevertheless the […]
What do earthquakes, the moon, and the earth’s magnetic field have in common? They’re all connected to the iron core deep inside our planet.On this week's podcast, join me on a journey to the center of the earth. First, Planetary Science Professor Raymond Jeanloz from the University of California Berkeley will guide us through the iron catastrophe, the event that formed the earth’s core. Surprisingly, it has a lot of do with the planetary impact that chipped the moon from […]
