November 22 marks the passing of Hans Adolf Krebs. Krebs was a German chemist who was awarded the 1953 Nobel Prize in Medicine for the discovery of the citric acid cycle or the Krebs cycle. The Krebs cycle is a series of chemical reactions that take place in cells where food is broken down into carbon dioxide, water, and energy. The reactions take place in the mitochondria of cells as part of the process of cellular respiration.
November 21 is Hieronymus Theodor Richter’s birthday. Richter was a German chemist who discovered the element indium with Ferdinand Reich. They discovered the element using the relatively new technique of spectroscopy. When a substance is heated, the light it emits can be passed through a prism to separate individual bands of color that are unique to each element. They isolated a substance that turned out to be a new element that gave off a vivid indigo spectral line and named it indium.
November 20 is Karl von Frisch’s birthday. Frisch was an Austrian zoologist who received a third of the 1973 Nobel Prize in Medicine for his discoveries involving bees. Frisch’s first discovery was bees have color vision. He proved this by feeding bees drops of sugar water placed on a blue card. Later he set the blue card in an array of gray cards. To an animal with no color vision, all the cards would look gray. The bees would fly straight to the blue card.
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".
