Over the weekend, a tiny spot on the sun erupted into a moderately sized solar flare that was particularly loud in radio waves. With the sound of a roaring wave, it completely drowned out radio communication all over the Earth between 28 MHz and 21.1 MHz. The recording above comes from either a short wave radio station or a Ham radio transmission, said amateur radio astronomer Thomas Ashcraft, who works with NASA’s Radio JOVE project.
You might think it'd be hard not to notice 68 million tons of rock and debris suddenly crashing down a mountainside. But when one of the biggest landslides of the past four years occurred in a remote region of Alaska , researchers knew almost everything about it except its exact location. Tracking it down took a coordinated effort between seismologists, geomorphologists, and ordinary citizens in a process that has become the new norm for finding large landslides around the world.
Editor’s note: NBC News MACH has partnered with the American Museum of Natural History to present three documentary films at the Margaret Mead Film Festival, which will be held in New York City from Oct. 19-22. In "Pre-Crime," filmmakers Monika Hielscher and Matthias Heeder examine the rise of predictive policing, which aims to stop crime before it occurs. The film led MACH to explore this new tool for law enforcement — its power and potential peril.
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".
