Ancient rock art discovered in Saudi Arabia shows more than 6,600 depictions of wildlife - proving the area was home to a vast range of creatures in prehistoric times. The engravings, some of which date back to 8,000BC, include images of rare antelope, aurochs, wild camels and African asses, previously not known to live in this area. Although the area is now a rocky desert, experts believe it would have been a haven for plant and animal life up until 6,000 years ago.
Facebook is trialling a 'downvote' button that allows users to signal if a comment is inappropriate or misleading. The new button, which appears to bring Facebook closer to having a 'dislike' button, is currently being tested on five per cent of android users in the US. Downvote counts aren't shown to the public, but Facebook says it will help the site gauge whether certain posts are inappropriate.
An asteroid larger than a blue whale will skim past Earth today - and it was only discovered on Sunday. The space rock, called 2018 CB, is set to blaze past at just one-fifth of the distance between our planet and the moon. The space agency describes asteroids as 'hazardous' if they come within 4,600,000 miles (7,403,00km) of our planet and this space rock will fly just 39,000 miles (64,000 kilometres) away. According to Nasa the asteroid will pass by at around 17:30 EST (22:30 GMT) today.
While looking like paper, they have a polypropylene plastic lining. In theory, both the paper and the lining are recyclable. But in practice, no conventional paper plant wants them because the lining clogs their mills #plasticpollution#lattelevyhttps://t.co/m43wPIRZNy
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".
