A Block on the Old ChipFor decades, computers have grown more powerful because chipmakers have been able to make ever-smaller transistors, allowing them to cram more onto a single chip. That steady march has always depended on optics—shorter wavelengths of light allowed chipmakers to draw smaller lines for circuit paths, which then can be closer together. It has become increasingly harder, however, to reach the high resolutions needed for ever-tinier features.
A new type of laser cavity that builds off a Nobel-winning development in physics can take on any shape and switch the flow of light with a magnetic field. “Being able to do this kind of thing with light is a very exciting prospect,” says Boubacar Kante, a physicist at the University of California, San Diego. Kante and his colleagues describe their so-called topological cavities in the current issue of Science. Normally, a laser cavity, where light amplification takes place, is shaped like a ring.
For neurologist Peter Bede, seeing someone he thinks might have amyotrophic lateral sclerosis (ALS) can be vexing. Unlike many disorders, even other neurological diseases, ALS is not an illness that can be identified by an examination and a few lab tests. “If I suspect multiple sclerosis, I do an MRI and do a lumbar puncture and that pretty much will confirm diagnosis,” says Bede, an ALS researcher at Trinity College Dublin.
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".
