In what they are calling a world first, nanoengineers at the University of California San Diego (UCSD) have delivered tiny drug-bearing motors into the stomachs of mice where the devices moved around via bubble propulsion. The locomotion method not only allowed the mini molecular machines to navigate, but it also changed the pH of the stomach to allow the successful dispatch of bug-clobbering antibiotics.
Supernova SN 2017cbv is located in the galaxy NGC 5643, about 55 million light years away, making it one of the closest supernovae recently discovered (Credit: UCSB)Thanks to a worldwide network of 18 robotic telescopes, researchers led by the University of California Santa Barbara (UCSB) were able to catch a brief blue glow in the sky which, they say, was the result of a different kind of supernova explosion.
Untreated mouse skin on the left versus skin that was treated with the drug UK5099 on the right (Credit: UCLA Broad Stem Cell Center/Nature Cell Biology)If stem cells can do everything from growing skulls to generating new heart tissue, you'd think they'd also be able to help regrow hair on balding heads. In fact, they soon might be able to do just that. Last year we saw that regular stem cells converted into epithelial stem cells (EpSCs) could be coaxed into growing new hair.
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".
