For the first time, female dark-eyed juncos have been found to burst into song in the wild. Although many female tropical birds sing, singing females are rare among northern, temperate songbirds. However, the behaviour is now becoming more common, and climate change may mean it becomes even more widespread. Dustin Reichard of Ohio Wesleyan University knew that female dark-eyed juncos (Junco hyemalis) sometimes sang in captivity, but only after being injected with testosterone.
A gene variant that arose decades ago in an Amish group seems to be enough to make people live ten years longer, as well as making them less likely to develop diabetes. The gene is called SERPINE1, and is known to make a protein that promotes ageing, known as PAI-1. But a faulty variant of this gene arose six generations ago in an Amish group, causing the people who carry one copy of the variant to produce half as much of the age-promoting protein.
It’s cold to start with, all that way from the sun. But at -203°C, the observed temperature of Pluto’s atmosphere is around 30 degrees colder than it should be theoretically. Now, the puzzle of why it’s colder than expected has been solved, and it comes down to the previously unappreciated shielding effects of tiny sooty particles that create a haze. Previously, all calculations to explain Pluto’s chilly air have focused solely on gases such as methane rather than tiny, sooty particles.
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".
