An asteroid the size of a house is set to pass close to the Earth on Thursday. The space rock will hurtle past our planet at a distance of about 42,000km (26,000 miles), bringing it within the Moon's orbit and just above the altitude of communication satellites. Nasa scientists say there is no risk of an impact, but the flyby does provide them with the opportunity to test their asteroid-warning systems. A global network of telescopes will be closely monitoring the object.
Scientists have shed light on what ancient Europeans looked like. Genetic tests reveal that a hunter-gatherer who lived 7,000 years ago had the unusual combination of dark skin and hair and blue eyes. It has surprised scientists, who thought that the early inhabitants of Europe were fair. The research, led by the Institute of Evolutionary Biology in Barcelona, Spain, is published in the journal Nature.
A UK zoo is taking part in a radical plan to save the world's last three northern white rhinos from extinction. At Longleat safari park, scientists have collected eggs from southern white rhinos - a closely related sub species - to use for IVF. The eggs will help researchers to develop the technology to help the remaining northern whites to reproduce. A back-up plan is to mix eggs from the southern white rhinos with sperm from northern whites to create a hybrid.
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".
