Until recently, the coldest temperature a gas could get to was "absolute zero" on the Kelvin scale — a beyond-freezing minus 273 degrees Celsius (-460 degrees Farenheit). Physicists at Ludwig-Maximilians University Munich and the Max Planck Institute of Quantum Optics in Garching have achieved a temperature colder than absolute zero. Such a discovery could help scientists understand concepts such as dark energy.
Packages constructed of DNA dubbed "DNA origami" might one day be used to create nanorobots capable of finding and destroying cancer cells in the human body. The nanorobots mimic a cell's receptor system in order to communicate with cells. The cells can carry materials — a "payload" — to cancer cells, and when the nanorobot detects the cells it's hunting for, it will spring into action. The study was published in Science on Thursday.
Google says it will stop redirecting Windows Phone users away from its mobile Google Maps website. This weekend, controversy erupted after users reported that attempts to access Google Maps on Windows Phone devices led to redirects to the Google homepage. Google confirmed the redirect on Friday, telling Mashable and other news outlets that the decision to redirect users away from Google Maps was because it had optimized its mobile Google Maps website for WebKit-based browsers.
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".
