Scientists Finally Made Carbyne—a Material Stronger Than Graphene—That Lasts

Several years ago, scientists calculated the properties of an exotic form of carbon—called Carbyne—and found that it promised more strength and stiffness than any other known material. Now, it’s finally been made in a stable form inside an Austrian lab.

Researchers from the University of Vienna in Austria report in Nature Materials that they’ve managed to syntehesize the material far more successfully than ever before. It’s proved so tricky in the past because Carbyne is a long one-dimensional chain of carbon atoms linked one to the other. Its structure makes it highly reactive, which means that as quickly as it’s manufactured, it’s destroyed.

But the Austrian researchers have found a way to make it while avoiding such destruction. They took two sheets of graphene, laid them on top of each other, then rolled the whole thing up to create a double-walled tube. Think of it as a graphene Thermos. Then, they synthesized the Carbyne inside the tube, providing a protective casing which allowed the material to remain in tact.

The record for stringing together carbon atoms like this in the past had been 100 in a row; now, the team can put 6,400 atoms together, and have them remain in a chain for as long as they want. That is, of course, as long as they sit inside the carbon Thermos. It remains to be seen how useful Carbyne will be whilst wrapped up, but for now it’s the best that researchers can achieve.

Regardless, other researchers will doubtless clamour to try and exploit the newly produceable material: Previous calculations have shown that Carbyne is stronger than both graphene and diamond, and around twice as stiff as the stiffest known materials. That sounds pretty promising to us.

Google’s latest feature will help you learn new skills and practice hobbies (GOOG)

Google wants to help you learn yoga.

The Californian tech giant is launching a new feature for its Calendar app to help users practice hobbies and reach goals that they set themselves.

You can set a Goal — learn Spanish, say — and set a desired frequency (twice a week, perhaps) and time (evenings, for example). It will then automatically slot in events to your calendar reminding you to do this activity, at a time when you don’t already have any events.

It might schedule your weekly run for Wednesday if that’s when you’re normally free — but if one week, you have a late meeting, it’ll automatically reschedule it for another time. Similarly, if the notification pops up but you can’t do it right then, you can tap "Defer" (like you’d hit Snooze on your alarm), and it’ll reschedule it for another available slot.

And using Google’s machine learning tech, it’ll learn about you as you use it — improving its scheduling over time based on your preferences.

"Calendars should help you make the most of your time—not just be tools to track events," product manager Jyoti Ramnath wrote in a blog post announcing the new feature. "So as Google Calendar turns 10 today (🎉), we’re excited to invest in more updates like Goals, and to help you find time for everything that matters—from your daily must-dos, to exercising more, to just a little "me time.’"

Here’s a GIF showing it in action:
