Increasingly, U.S. teens are trading sleep time for screen time. That’s the finding of a new study. It analyzed survey data from hundreds of thousands of adolescents. And they showed that the share of teens who are losing more sleep and logging more screen time rose dramatically between 2009 and 2015. Most sleep experts agree that from ages 12 to 17, teenagers need about nine hours of sleep a night. When teens don’t get enough shut-eye, their bodies and minds suffer.
Temperatures on Earth can soar above 40° Celsius (104° Fahrenheit) and drop well below 0 °C (32 °F). Despite that variability, scientists can calculate a global average. Countries around the world have had reliable weather monitoring stations on land and sea since about 1880. In the 1960s, researchers also began taking the Earth's temperature with the help of satellites. Satellites don't measure temperature directly. Instead they measure radiation given off by oxygen that's in Earth's atmosphere.
Standing up for your beliefs when they run contrary to those of everyone around you sounds like a prescription for stress. It could at least leave you very uncomfortable. But new research suggests that not backing down might actually prove rewarding. It all depends on your goals, says Mark Seery. He is a psychologist who studies how people deal with stress. He works at the University at Buffalo in New York. The human body has two basic reactions to this type of conflict.
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".
