By now, the 20-second rule for washing your hands is probably seared into your brain for the rest of your days. But all that scrubbing could be for naught as soon as you touch your phone, which can carry up to 10 times more germs than a toilet in a public restroom. That’s where the double-sided HÄNS Swipe screen cleaner comes in handy: it both disinfects and polishes screens, and you can find it on Amazon for $15.

The HÄNS Swipe gets your screen clean in two simple steps. To start, wipe down your screen with the “cleaning side,” which is pre-soaked in an antimicrobial solution to break down grease, dirt, and microbes that might be hanging out on your device. Then you turn the Swipe over and use the polishing side, a layered antimicrobial sheet that gets rid of any fingerprints and other residue, leaving your screen sparkling. And unlike single-use wipes, the HÄNS is refillable, and you can find the cleaning solution for $10 on Amazon.

Now that you’ve got your screen clean, what about your keyboard? Just like your cell phone, your keyboard is nothing more than a Petri dish teeming with microscopic invaders. But the new HÄNS Ultra-Clean ($15) works to clean up gunk and microbes on your keyboard, headphones, adapters, and even certain screens. Simply dab the reusable antibacterial sheet in the solution and start cleaning.

University of California and McMaster University Are Offering Their Learning How to Learn Course Online for Free

If you've ever stayed up late cramming information the night before an exam, it probably didn't go well. Or maybe you tried doing the right thing by spending days or even months studying a subject, only to realize you weren't retaining the information. These failed attempts may have you believe you're just not cut out for the subject matter, but that's not always true. In the course Learning How to Learn from Coursera, you can understand what it takes to truly understand new information, as well as the key strategies and habits you can employ to make it all stick.

Learning How to Learn is taught by Dr. Barbara Oakley, a Ramón y Cajal Distinguished Scholar of Global Digital Learning at McMaster University, along with Dr. Terrence Sejnowski, who holds the Francis Crick Chair at the Salk Institute and is a professor at the University of California, San Diego. Throughout the weeks, they’ll teach you how to combat procrastination, how our brains process information, and the importance of breaking up new material into bite-sized chunks. You’ll also cover how taking breaks, getting sleep, and exercising are just as important as studying when it comes to learning something new.

According to Coursera, to finish the class in the typical four-week time, most students devote about three hours a week to the online videos, readings, quizzes, and coursework. There’s also no need to cram—which you’ll learn is not an effective learning tool—as this course is self-paced.

The course itself is free, but if you want a certificate of completion to share on your LinkedIn and resume, it will cost $49. Signing up for the certificate also gives you access to graded assignments, whereas the free version only allows you to read the course material.
