In Theory, a Vampire Could Suck Your Blood in 6.4 Minutes

There's something undeniably creepy about the legend of vampires drinking blood through a single bite to the neck, but just how long would they have to spend clamped on an artery to get a decent meal? As Gizmodo reports, this question is exactly what a team of physics students at the University of Leicester sought to answer in a recently published study.

The students' findings, which appear in their school's Journal of Physics Special Topics, look at the amount of time required to drain a human body of 15 percent of its blood through two fang-sized puncture holes in the neck. The group settled on 15 percent because anything more than that starts to become fatal, which means the vampire's victim wouldn't be of much use to them in their army of the undead.

Assuming the vampire wouldn't be doing any actual sucking, they calculated the rate at which blood would gush through two 0.5-millimeter bite marks in the carotid artery. For humans with an average amount of blood flowing through their veins, it would take a vampire approximately 6.4 minutes to drain them of .75 liters of it. That means a vampire could enjoy a satisfying meal while still having a decent window to make its escape.

The playful report was released in honor of the 85th anniversary of the film Dracula, which starred Bela Lugosi in the title role. The next time you watch the 1931 horror classic, you can judge how the blood-sucking science holds up.

Sylvia Plath's Pulitzer Prize in Poetry Is Up for Auction

A Pulitzer Prize in Poetry that was awarded posthumously to Sylvia Plath in 1982 for her book The Collected Poems will be auctioned on June 28. The Los Angeles-based Nate D. Sanders Auctions says bidding for the literary document will start at $40,000.

The complete book of Plath’s poetry was published in 1981—18 years after her death—and was edited by her husband, fellow poet Ted Hughes. The Pulitzer Prize was presented to Hughes on Plath’s behalf, and one of two telegrams sent by Pulitzer President Michael Sovern to Hughes read, “We’ve just heard that the Collected Plath has won the Pulitzer Prize. Congratulations to you for making it possible.” The telegrams will also be included in the lot, in addition to an official congratulatory letter from Sovern.

The Pultizer’s jury report from 1982 called The Collected Poems an “extraordinary literary event.” It went on to write, “Plath won no major prizes in her lifetime, and most of her work has been posthumously published … The combination of metaphorical brilliance with an effortless formal structure makes this a striking volume.”

Ted Hughes penned an introduction to the poetry collection describing how Plath had “never scrapped any of her poetic efforts,” even if they weren’t all masterpieces. He wrote:

“Her attitude to her verse was artisan-like: if she couldn’t get a table out of the material, she was quite happy to get a chair, or even a toy. The end product for her was not so much a successful poem, as something that had temporarily exhausted her ingenuity. So this book contains not merely what verse she saved, but—after 1956—all she wrote.”

Also up for auction is Plath’s Massachusetts driver’s license from 1958, at which time she went by the name Sylvia P. Hughes. Bidding for the license will begin at $8000.

New 'Eye Language' Lets Paralyzed People Communicate More Easily

The invention of sign language proved you don't need to vocalize to use complex language face to face. Now, a group of designers has shown that you don't even need control of your hands: Their new type of language for paralyzed people relies entirely on the eyes.

As AdAge reports, "Blink to Speak" was created by the design agency TBWA/India for the NeuroGen Brain & Spine Institute and the Asha Ek Hope Foundation. The language takes advantage of one of the few motor functions many paralyzed people have at their disposal: eye movement. Designers had a limited number of moves to work with—looking up, down, left, or right; closing one or both eyes—but they figured out how to use these building blocks to create a sophisticated way to get information across. The final product consists of eight alphabets and messages like "get doctor" and "entertainment" meant to facilitate communication between patients and caregivers.

This isn't the only tool that allows paralyzed people to "speak" through facial movements, but unlike most other options currently available, Blink to Speak doesn't require any expensive technology. The project's potential impact on the lives of people with paralysis earned it the Health Grand Prix for Good at the Cannes Lions International Festival of Creativity earlier in June.

The groups behind Blink to Speak have produced thousands of print copies of the language guide and have made it available online as an ebook. To learn the language yourself or share it with someone you know, you can download it for free here.
