Many male birds-of-paradise are noted for their bright colors and iridescent feathers, but several species of these tropical marvels also sport super-black plumage. Now researchers have teased out the structural secrets behind these light-absorbing feathers, which rival even the deep velvety blackness of some manmade materials. Feathers, like most opaque objects, typically get their color one of two ways.
Even though daytime temperatures in the tropics of Mars can be about –20°C, a summer afternoon there might feel about the same as an average winter day in southern England or Minneapolis. That’s because there’s virtually no wind chill on the Red Planet, according to a new study—the first to give an accurate sense of what it might feel like to spend a day walking about on our celestial neighbor.
About 3900 years ago, one of the biggest cradles of Bronze Age civilization fell apart. For unknown reasons, people fled the Indus Valley in what is today Pakistan and northwestern India to establish smaller villages and farms farther to the east. Now, analyses of cave formations from the region bolster the notion that changes in the strength of that semiarid region’s summer monsoon may have played a major role in this cultural upheaval, and others like it.
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".
