The immense popularity of the bright, energy-saving electrical components called light-emitting diodes (LEDs) has been a boon for the environment. But researchers are also discovering it has come at a rather serious cost. Thanks partially to solid-state lighting's bigger bang for your buck, the growing problem of light pollution is showing no sign of slowing, which is bad news for our ecosystems and our health.
Neutrinos have a reputation for playing hard to get. Tiny, sub-atomic particles that have no charge and close to zero mass, they usually slip past Earth's atoms leaving barely a trace of their presence. But not all run past unscathed. New research confirms highly energised 'ghost particles' can be stopped dead in their tracks, a discovery that doesn't surprise theorists but could open new ways toward seeing the most hidden parts of our planet.
For the past two decades, NASA has continuously kept an eye on our planet's biosphere as it pulses and ebbs with the seasons. The data is invaluable to researchers, but the time-lapse imagery also provides us with a breathtaking visualisation of Earth's most unique characteristic – life. The Sea-viewing Wide Field-of-view Sensor (SeaWiFS) was launched in 1997, and spent the next 13 years looking down on us from its orbit 700 kilometres (about 435 miles) overhead.
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".
