False rape accusations are an anomaly.

True rape accusations are a norm.

You’re, quite literally, more likely to be killed by a comet than falsely accused of rape.

So stop bringing them up like they’re…

Not So Fast on the ‘Female Penis’

Scientists discovered a cave-dwelling insect whose females have a penis and males have a vagina—or so the headlines say. But the ‘female penis’ isn’t really that at all.
When is a penis not a penis? When it belongs to a female insect, say scientists investigating the animal kingdom’s first documented instance of an evolutionary genital swap. The Brazilian cave-dwelling male, Neotrogla, has been found to possess a vagina and vice versa, making this an historic case of sex organ switcheroo. 
Where the discovery is truly unique is that the species’ females take on both the traditionally male role in copulation—using an “elaborate, penis-like structure… [to] anchor the female to the male”—as well as retaining their usual biological function of providing the egg. A woman’s work really is never done.
Interestingly, scientists don’t just class every animal with a penis as male: determining the sex as such comes down to how big a creature’s gametes are. The largest of these are usually provided by females (the egg), which, in Neotrogla’s case, holds. But the real game changer is that they also take the lead when it comes to mating—inserting their penis (or, more accurately, gynosome) into males for fertilization and nutrients. Given that their mating sessions can last up to 70 hours, their bedroom—well, cave—performances seem pretty darn impressive.

April 21st 1989: Game Boy released

On this day in 1989, the original Game Boy was released in Japan. It was later released in North America in August and in Europe in September 1990. The device was one of the first handheld gaming consoles, making it a groundbreaking invention that revolutionised the concept of videogames by allowing for them to be played on-the-go. The Game Boy was relatively cheap compared to rivals on the market (costing ¥12,500 at launch) and was a huge success, selling almost 120 million units. The designers of the console, the same team who gave us the Game & Watch series, ensured the device handled in a similar way to the familiar Nintendo Entertainment System (NES) with its eight-way D-pad controller and four buttons. Some of the most popular original Game Boy games included: Super Mario Land, which sold over 18 million copies; Tetris, which sold 35 million copies; and the first Pokémon games, released in 1996. Nintendo continues to produce handheld game consoles and the popularity of the Mario and Pokémon franchises endures. The most recent handheld was the Nintendo 3DS, which features touch screen control and 3D graphics; technology only dreamed of in 1989.

The New Science Behind Picky Eaters
It’s one thing for your brother to hate green vegetables, your beloved to avoid dairy, or your best friend to swear off offerings from the entire country of India. 
But good luck cooking for a guest who turns his nose up at mangoes but not pineapples, picks out tomato slices from a burger, and mercilessly plucks at walnuts studding a brownie. It’s like you need a course in Bayesian statistics to figure out his contradictions.

Evidence of 3.5-Billion-Year-Old Bacterial Ecosystems Found in Australia | ScienceDaily

Reconstructing the rise of life during the period of Earth’s history when it first evolved is challenging. Earth’s oldest sedimentary rocks are not only rare, but also almost always altered by hydrothermal and tectonic activity. A new study from a team including Carnegie’s Nora Noffke, a visiting investigator, and Robert Hazen revealed the well-preserved remnants of a complex ecosystem in a nearly 3.5 billion-year-old sedimentary rock sequence in Australia.
