An Indiana archery company that sued a prominent live action role-play (LARP) website will drop its claims that the website's owner infringed two patents on foam arrows.

John Jackson, founder of Global Archery, told Ars that he decided to drop his patent case against Larping.org owner Jordan Gwyther after analyzing a patent on the German-made iDV arrows that Gwyther sells.

The lawsuit isn't over, however—Jackson also sued Gwyther for allegedly infringing his trademark, for buying Google ads keyed to it, and for false advertising.

If you missed out on the lowest-yet official price for the Xbox One during last year's Black Friday and holiday sales, Microsoft has an even better deal going on now as part of its Spring Sale.

All Xbox One bundles have been reduced by $50 at major retailers like Amazon, Best Buy, Target, and Gamestop. But if you buy through the Microsoft Store before March 31, you'll be also get a free copy of Assassin's Creed Unity, Watch Dogs, or The Crew in addition to any other bundled games.

While this price drop is officially a "limited time, while supplies last" type of deal, it could presage a more permanent reduction for Microsoft's console, which is selling slowly relative to its main competition. Back in 2014, many retailers temporarily lowered the price of the Xbox One by $50 well before Microsoft officially lowered the price by pulling Kinect out of the bundle.

THE WOODLANDS, Texas—Ceres is a cold, dead world today. But it wasn't always so, and as researchers delve deeper into images and data collected by the Dawn spacecraft, they continue to find intriguing hints about a world that likely had a large, subsurface ocean during the early days of the solar system. They also have found a number of features on the surface of Ceres they cannot yet explain, deepening the mystery of the dwarf planet’s evolution.

The largest object in the asteroid belt, measuring some 950km across, Ceres is roughly the size of Texas. So perhaps it's fitting that scientists gave their most detailed briefing yet about the planet in a darkened conference room in The Woodlands, just north of Houston, at the Lunar and Planetary Science Conference on Tuesday. Here the mysterious bright spots of Occator crater and other parts of the small world shone brightly.

These parts also intrigued. As the Dawn spacecraft approached Ceres in 2015, it revealed a large bright spot in Occator crater, but as the spacecraft has flown down to within 400km of the world’s surface and produced a global map at a resolution of 35 meters per pixel, scientists have found many bright spots in the crater likely due to salt deposits. Still, the brightest one at the center remains most interesting.

Tesla has decided that it won’t be making the 10kWh stationary storage batteries it unveiled last April, instead focusing exclusively on the 7kWh version.

The 10kWh version of Tesla’s Powerwall was made to be used as backup storage only—its nickel-cobalt chemistry limited the user to cycling the battery 500 times, so daily use was out of the question. The 7kWh battery, on the other hand, is made to integrate with solar panels, and due to its nickel-manganese chemistry, Tesla said it could be cycled 5,000 times.

After Tesla quietly removed the option for a 10kWh battery on its website, the company confirmed in an e-mail to Greentech Media that the larger version had been discontinued. "The Daily Powerwall supports daily use applications like solar self-consumption plus backup power applications, and can offer backup simply by modifying the way it is installed in a home," the e-mail read. "Due to the interest, we have decided to focus entirely on building and deploying the 7kWh Daily Powerwall at this time."
