Scientists Destroy Entire Chromosome with CRISPR Researchers have managed to wipe out an entire mouse chromosome using CRISPR-Cas9. They aimed numerous double-strand breaks at either the centromere or the long arm of the Y chromosome, causing it to fragment and become deleted from XY mouse embryonic stem cells in vitro.The centromere-targeting approach also resulted in Y-chromosome loss when it was applied to mouse embryos in vivo.Read Full Article »
NEW YORK (Reuters Health) - Kids who don't get vaccines when they see their pediatrician for a sick visit - despite being due for the shots - are more likely to fall behind on immunizations and routine check-ups, according to a new study. "It's pretty common that kids will come in (for a sick visit) at a time when they should be getting their shots," said Steve Robison, the study's author and a researcher at the Oregon Immunization Program, part of the state's health department.
NEW YORK (Reuters Health) - Children from poorer neighborhoods who are hospitalized are more likely to die before discharge than kids from wealthier areas, according to a new study. These differences persisted even though the number of deaths for all kids at the hospitals studied was lower than expected.
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".
