Locked away in the Arctic permafrost is what's frequently called the "ticking time bomb" of climate change—methane, a greenhouse gas many times more powerful than carbon dioxide. There's widespread worry that, as the permafrost thaws, large amounts of methane will spew into the Earth's atmosphere, worsening the effects of climate change. There's reason to be concerned.
One of the most common types of asteroid zipping through our solar system may have originated as giant chunks of space mud, argues a new paper out today in Science Advances. Yes, mud. When I first saw this study, I assumed that I was taking the name of the hypothesis it describes—the "mudball model"—too literally. So I phoned author Philip Bland, a planetary scientist at Curtin University in Perth, Australia. "I'm sure you don't mean mudballs in space," I said. He cleared it up for me.
Countries that rely on nuclear power, including Canada and the US, will have to reckon with their nuclear waste. Used fuel stays radioactive for a million years or longer, and experts say the safest place for it is deep underground, where it can ideally sit undisturbed. But our world, in a million years, will look much different than it does today.
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".
