According to scientists, a poison arrow in the quiver may let loose a very sticky nether-region massacre.
The poison in question has spattered from the tips of African weapons for centuries, rubbing out wild beasts and halting the hearts of warriors. But, according to a study in the Journal of Medicinal Chemistry, a crotch shot of an ancient toxin called “ouabain” can also take out sperm. By tweaking the poison’s chemical backbone (or scaffold), it can selectively paralyze trouser troops and prevent them from storming eggs, the authors report.
The study’s authors, led by Shameem Sultana Syeda of the University of Minnesota, are optimistic that, with further aiming, the poison’s progeny could one day strike as a safe, reversible male contraceptive.

It’s been quite an unexpected decade at Tesla. In 2007, if you said that the EV company would release an all-electric sedan that became one of the fastest accelerating vehicles of all time and sold tens of thousands of units with numerous hardware and software improvements along the way, you’d have been sent to the loony bin. And if you then predicted the company would release an all-electric SUV that would do the same and develop and release (sort of) an affordable, stylish, and long-range EV... well, maybe you’d have been mistaken for a member of the Musk family.
And yet, Elon Musk and Tesla have done all those things with the Model S, Model X, and Model 3. The company has gone further with things like the Gigafactory; home, commercial, and utility battery products; and previews of the new Tesla Roadster and Tesla Semi, too. To be sure, Musk has made a lot of ambitious promises and really missed a lot of deadlines over the years—but people who have bet against Tesla over have lost a lot of money. (Tesla's stock price is up almost 1700 percent since its June 2010 IPO, fyi.)
Warning: The following preview outlines general details for the premise of Counterpart, a new Starz sci-fi series debuting this weekend.
The “actor as multiple roles” genre has been done in a seemingly infinite amount of ways as of late: clones, siblings, whatever Cloud Atlas was. With Starz' new series Counterpart debuting this Sunday (8pm ET), the premise gets a slight twist. Beloved institution JK Simmons (everything from those insurance ads to Justice League and Whiplash) portrays mild-mannered office man Howard and alternate-universe spy bad-ass Howard Prime.
Confused? Luckily, audiences get the gist of this situation early in the series premiere: 30 years ago during the Cold War, scientists were experimenting when something went wrong, opening a passage between two seemingly distinct worlds. “Go through this door,” bossman Peter tells Howard. “And you’re in a world identical to ours.”

The online game-subscription model has generally waned in recent years, overtaken by the popularity (and apparent profitability) of the "free-to-play" (F2P) paradigm. One of the earliest MMORPGs to switch to a F2P model, the Trion-published Rift, announced a curious change coming to its payment model: a branch-off of one Rift server, and its entire gameplay and payment structure, to return to the flat subscription model later this year.
As reported by Kotaku, the game's developers announced plans for this new version, dubbed Rift Prime, in a Friday blog post. The plan actually began life months earlier when Trion asked fans about the idea of a "challenge server" product—meaning, a version of the game that was harder and segregated interested players into their own, higher-difficulty pool of players. Fan response to the pitch went a different direction.
The players' "strongest cues," the devs write, revolved around "how to make the business model more appealing."

Proteins are chains of amino acids, and each link in the chain can hold any one of the 20 amino acids that life relies on. If you were to pick each link at random, the number of possible proteins ends up reaching astronomical levels pretty fast.
So how does life ever end up evolving entirely new genes? One lab has been answering that question by making its own proteins from scratch.
Way back in 2016, the same lab figured out that new, random proteins can perform essential functions. And those new proteins were really new. They were generated by scientists who made amino acid sequences at random and then kept any that folded into the stable helical structures commonly found in proteins. These proteins were then screened to see if any could rescue E. coli that were missing a gene essential to survival.

DETROIT—Once upon a time, the North American International Auto Show was a mighty thing indeed. The American auto industry ruled the world, and this was their home event with all the bells and whistles that implies. But the world has changed. For one thing, people can and do use the Internet to work out what car they're going to buy. And with the LA Auto Show, CES, and NAIAS in such close proximity to each other on the calendar, there just aren't enough new things to fill all three events. The take-home impression from NAIAS this year—hot on the heels of a mediocre CES—was of a lackluster performance with little in the way to stop one in their tracks.
Ford opened the events at the Cobo Center with a trio of new models that we covered early in the week. Mercedes-Benz had a new G-Class that looks almost identical to the 1979 model, an example of which could be seen embedded in synthetic amber outside the front doors. By midweek this nearly-50 ton act of corporate whimsy was roped off, riven by cracks thanks to the sub-freezing temperatures. BMW gave the i8 hybrid a mid-life bump, and Audi showed its new A7 on this continent for the first time.
Tim Herrick, chief engineer for the 2019 Silverado, stopped by the Roadshow stage during the 2018 Detroit Auto Show to go over all the changes that his team made to the new truck.

For millennia, humans have been captivated by Mars. To the ancient Romans, the “red planet” represented the god of war, presiding over conquest and glory. To the 19th-century astronomer Giovanni Schiaparelli, it was a world connected by vast canals, evidence of an advanced civilization. Today, our cosmic neighbor is a place to be explored, analyzed, and understood; the prospect of setting foot on Martian soil seems tantalizingly close.
But if the board game First Martians is anything to go by, we shouldn’t bother. Mars doesn’t want us.
