For decades scientists have debated how, where and when the wolf became the dog. Now a new study hints that dogs were domesticated just once, challenging a previous claim about how many times humans befriended canines. In a paper published this week in Nature Communications Krishna Veeramah at Stony Brook University and colleagues argue that dog domestication occurred once, sometime between 20,000 and 40,000 years ago. Early efforts at nailing down the time and place of domestication varied wildly.
We humans have left our mark on the entire planet; not a single ecosystem remains completely untouched. But some landscapes have been affected less than others. And the extent to which the earth can provide habitats for plants and animals, sequester atmospheric carbon and regulate the flow of freshwater depends on the vastness of the least affected regions. These tracts, where human influence is still too weak to easily detect by satellite, are prime targets for conservation.
For decades bear biologists have known that bears engage in a delightful ramble variously dubbed “sumo strutting,” “cowboy walking” or, simply, the “bear dance.” Many researchers have guessed at the reason, but a recent study finally offers solid clues. As they walk, the bears vigorously twist their feet into the ground. Sometimes they step into footprints left behind by other bears after giving the prints a good sniff.
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".
