Three of the four major grains on which the growing world population depends are vulnerable to global warming, says a new meta-analysis based on more than 70 studies. Farmers have probably known that plants have optimal ranges in which they grow best since planting the first wheat some 23,000 years ago. Now science has proved the point. The four crops on which humankind depends most are wheat, rice, maize, and soybeans. These are responsible for two-thirds of human caloric intake, says the team.
Three tombs dated to the Ptolemaic Period, more than 2,000 years ago, have been discovered in the Nile Valley, the Egyptian antiquities ministry said on Wednesday. The discovery was made in an area called al-Kamin al-Sahrawi, south of Cairo. The discovery of sarcophagi and clay fragments suggests that the archaeologists found a major necropolis used over generations. It was evidently used sometime between the 27th Dynasty (when ancient Egypt was under Persian control, from 525 B.C.E. to 404 B.C.E.)
The velociraptor lookalike leaps with slavering jaws, terrifying if slightly ridiculous as it waves its little arms at you, and grabs your carrot. Screams, crunching. Cellulose flies in all directions. "Cut!" George Lucas Jr. screams. Sound wrong? A strange dinosaur named hilesaurus, because it was found in Chile, would have fit the bill.
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".
