The t-shirt deal of the day over at RIPT Apparel is the Back To The Future-inspired shirt called “88 M.Y.A.”

The tee, by artist Nathan Davis, went on sale at RIPT today, Tuesday, April 12, 2011, at midnight CST, and will continue for 24 hours from then, and once it’s over, it will not be sold on the site anymore.

Of the design, the artist said, “88 M.Y.A. (88 Million years Ago)” honours the grisly discover found just outside Hill Valley, California, which has puzzled most scientists, and made one Dr. Emmett Brown surprisingly jumpy.

Today marks the 50th anniversary of Yuri Gagarin‘s historic space flight in the Vostok 1 spacecraft, which made the Soviet cosmonaut the first human in space. During a 108-minute flight on April 12, 1961, Gagarin was the first human to escape Earth’s gravity and achieve orbit.

Each year, this milestone is celebrated around the globe with Yuri’s Night, which this year includes 500 parties in 72 countries on 6 continents. There’s various types of parties — some are free, others are ticketed — which can range from intimate gatherings to galas with over 10,000 attendees, with several Observatories hosting events, as well as one at the Kennedy Space Center in Florida. Visit the Yuri’s Night Events List page to find a party in your area.

Amazon has announced that a new version of the Kindle is available now for pre-order for only $114, and will be released on May 3, 2011.

The new version of the popular e-reader device is called the
Kindle with Special Offers. It’s the same device as the existing 6-inch graphite Wi-Fi version (that’s $139), but it’s $25 less. And why is it $25 less? Because the $114 “Special Offers” version includes ads — but fear not, the ads are NOT within the ebooks; they only appear on the screensaver (which, let’s face it, no one pays attention to) and at the bottom of the home screen.

I know, lots of people freak out at the thought of ads — and I haven’t seen this new version, so I can’t say from experience — but seriously, if the ads don’t interfere with the reading, I’d say it’s well worth the low price. I have the 6-inch graphite Wi-Fi Kindle and believe me, if I didn’t already own it, I’d grab the $114 version without hesitation. Actually, I’ve owned every generation of Kindle after the first one and I just love it more and more with each upgrade.
