The bionic hand closes slowly. Its slender metal digits whirr as they jitter into a loose fist, as though they are wrapping around an invisible baton. "OK, closed," says the test subject. The test subject is Amanda Kitts. In 2006, a Ford F350 hit her Mercedes sedan head-on. The collision rent the truck's tire from its chassis and shoved the axle into Kitts' car, where it nearly severed her arm. "It wasn't completely off, but it was mincemeat," she says. "There was no saving it.
Too much caffeine, whether from coffee, tea, or energy drink, can ruin your day. Here's why your daily jolt makes you jittery, and what you can do to get rid of an unwanted buzz.How Much Is Too Much?First, a technical question: How much caffeine is too much? From a regulatory standpoint, answering this question has proved next to impossible. The crux of the issue is that caffeine toxicity varies according to how quickly your body processes the molecule.
While a science fiction television show may seem like a strange place to learn about cryptography, an episode of Stargate: Universe hides lessons in plain sight. I know, because I was the backstage professor.Top image: Just what does Dr. Rush scribble on all those chalkboards, whiteboards, and notebooks throughout Stargate: Universe, "Human"?

How ingenious? The system the researchers developed relies on something called "vibration-induced kinesthetic illusions." Essentially: Vibrating a tendon at a frequency between 70 and 115 Hz makes you feel like its associated joint is moving. Even if that joint does not exist.
Muck Rack makes it simple to find people, tweets, or articles that mention any name, keyword, company, hashtag etc. We've compiled this guide to help you make the most of your search.
Selecting a term
Start searching tweets, articles from media outlets, articles mentioned in tweets, journalists'
names, titles and bios with some suggested searches:
Companies or Topics (e.g. iPhone, Microsoft)
Phrases (e.g. "cloud computing") — use quotes to keep the terms together
Twitter handles (e.g. @username) — returns those who have mentioned or replied to
Names (e.g. "David Pogue")
Hashtags (e.g. #sxsw, #london2012)
Bio details (e.g. vegan, Olympics, father)
Muck Rack's Advanced Search allows for many boolean operators.
Find results that mention multiple specified terms, use AND or
+. For example, ensure each result contains both Elon Musk and Mark Zuckerberg by
searching Musk AND Zuckerberg or Musk + Zuckerberg.
Use the operators OR or , to broaden your search when you'd like either of
multiple terms to appear in results. (This is the default behavior of our search when no operators
are used). For example, results will contain either cake or cookie by searching cake OR cookie or cake,cookie
Use NOT or - to subtract results from your search. For
example, searching Disney will yield results about the Walt Disney Company as well as Walt Disney
World Resort. To exclude mentions of Disney World, search for Disney -World or Disney
When using one of these operators with a phrase, enclose it in quotation marks. For example, you can
find results about smartphones excluding Apple's iPhone 4S by searching smartphone -"iPhone
Exact case matching or punctuation
If you're searching for a brand name or keyword that relies on specific punctuation marks or capitalization, you can
find results that match your exact query by adding matchcase: before the keyword you're searching for, like matchcase:E*TRADE .
Use parentheses to separate multiple
boolean phrases. For example, to find journalists talking about having fun in Disney World or
Disneyland, search for ("disney world" OR disneyland) AND fun.
An asterisk can be used to search for any variation of a root word truncated by the asterisk. For example, searching for admin* will return results for administrator, administration, administer, administered, etc.
A near operator is an AND operator where you can control the distance between the words. You can vary the distance the near operation uses by adding a forward slash and number (between 0-99) such as strawberries NEAR/10 "whipped cream", which means the strawberries must exist within 10 words of "whipped cream".
