Saturn's moon Mimas — sometimes called the "Death Star" for its resemblance to the iconic "Star Wars" weapon — might have a core that's oblong like a football. As Cassini flew by Mimas, the probe took pictures, and those photos enable scientists back on Earth to see how the moon spins on its axis — how it wobbles a bit. The researchers found something odd: a solid core, which Mimas was assumed to have, didn't fit the data they were getting.
With a nod to the "Voltron" Defender of the Universe" — the animated show in which five lion-shaped robots link up to form a giant machine that fights evil — a team of scientists has created robots that work together and decide which one will lead them. Typically, if a robot's "brain" (or central processor) gets damaged or destroyed, the machine must take a trip to the great robot repair shop in the sky (or technician's bench).
As Hurricane Irma winds down — and a message from a Florida sheriff – saying that shooting guns at the storm would not turn it aside — brings to mind the question of why we can't control hurricanes. The short answer is that we can't control weather at any scale, and hurricanes are no exception. "We have no real idea how to control weather in the sense of a hurricane," John Moore, a scientist at Beijing Normal University, told Space.com.
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 Obama AND Romney or Obama + Romney.
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, search for democrat OR republican to find results that refer to
Democrats and/or Republicans.
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".
