Above a waste-processing plant in the Swiss countryside towers a grid of 18 silver fans. This edifice, about the size of four shipping containers, is part of the first commercial system for capturing the greenhouse gas carbon dioxide (CO ) from air. Built by Zürich-based firm Climeworks, the plant began operating in May. Researchers who are studying climate-change mitigation think that carbon capture is crucial for meeting the goals of the 2015 Paris climate agreement.
Through photosynthesis, plants and some bacteria use energy from sunlight to turn carbon dioxide and water into useful organic chemicals. Chemists have serious enzyme envy because designing inorganic catalysts that can do the same is difficult. Now researchers have developed a catalyst that can turn CO into ethanol and propanol when operating at voltages that solar cells could provide (Proc. Natl. Acad. Sci. USA 2017, DOI: 10.1073/pnas.1711493114).
Matthew Porteus remembers the first time he treated a patient in a sickle-cell crisis. The young woman was experiencing a deep, intense ache in one of her limbs. The pain, caused by a blocked blood vessel, is common in people with a blood disorder called sickle-cell disease. Once he found out that she had such a condition, Porteus knew the exact cause of her troubles — the point mutation in one of the genes that encodes part of the oxygen-carrying protein haemoglobin, found in red blood cells.
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".
