Today’s Headlines

Amazon Prime Day is here

It’s Christmas in July, otherwise known as Amazon’s Prime Day. Today and tomorrow the retail giant offers tens of thousands of steep discounts on all kinds of items, ranging from Amazon’s own devices to home and outdoor upgrades, and everything in between.

The inside story of Twitter’s new redesign

In January, Twitter gave a small percentage of users access to a new-look desktop experience. Today, the company is rolling out the refresh to everyone, marking Twitter’s first desktop redesign in seven years. No, you still can’t edit tweets, and yes, white supremacy still runs rampant on the platform. But the site is noticeably faster, the design more customizable, and you can now save tweets in bookmarks for later reference.

But just a few inches below that hardened surface is something else: frozen gases like carbon dioxide, and even frozen water. What if you could use an insulating material over the surface to create a greenhouse effect warm enough to make Mars habitable? That’s exactly what a new paper proposes, suggesting silica aerogel as that insulant. The cool part? We can try it here on Earth first.
