If you read these columns each week, you are probably interested in science and the exciting new discoveries that arise every day. Yet the challenges to scientific evidence and the conclusions they generate have rarely been more pervasive or ominous. Perhaps it is time to discuss how science works and how scientists try to move forward and make a difference.During our training, we are taught the scientific method, which involves forming a theory and testing it with experimentation.
In the early 1500s, the Aztec empire comprised about 25 million people. That changed with the arrival of the Spanish conquistadors led by Hernán Cortés, which marked the beginning of the end for the Aztec empire. Though Cortés was initially forced to withdraw from the Aztec capital, Tenochtitlán, he returned 10 months later. He laid siege to the city, which was already weakened by famine, drought and a disease epidemic.
Pancreatic cancer is a silent killer. By the time symptoms appear, the cancer is usually too advanced for successful treatment. Sadly, despite remarkable changes in the mortality rate of other cancers, only 5 percent of people diagnosed with pancreatic cancer are alive five years later. A new blood test finally provides some hope that pancreatic cancer could be detected early, making it potentially treatable.The pancreas is a small pear-shaped organ behind the stomach.
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".
