Imagine that Brian promises to drive you to the airport but never shows up, and you miss your flight. When you confront Brian, he tells you that he remembered his promise but decided to watch a movie instead. Would you be angry? You betcha!-->
All complex life, including plants, animals and fungi, consists if of eukaryotic cells, cells with a nucleus, transport mechanisms and often organelles like mitochondria that perform the functions an organism needs to stay alive and healthy. Humans have 220 different kinds of eukaryotic cells which control everything from thinking and locomotion to reproduction and immune defense.
Because of that commonality, the evolution of the eukaryotic cell is considered one of the most critical events in the history of life on Earth. Without it, earth populated entirely by prokaryotes, single-celled organisms such as bacteria and archaea, with no chance at all of filming "Guardians of the Galaxy" or celebrating Christmas.
A new analysis to be presented next week at the American Geophysical Union's Fall Meeting in San Francisco says that extreme climate and weather events such as record high temperatures, intense downpours and severe storm surges are more common in many parts of the world.
It's hard to be sure. High quality weather records only go back about 30 years and even suspect quality records only go back 100, so there is inference between modern record-keeping and the data trapped in tree rings and ice cores from ancient times.

Sometimes it may seem like your dog doesn’t want to listen.
But in our study, however, we’ve found that he may understand more than he lets on.

A dramatically-named “weather bomb” exploded across the UK in the past week, bringing winds gusting up to 144 mph on outlying islands.
But despite the cool name these “bombs” are more common than you might think.-->
In all of the money and outreach trying to convince more Americans to become scientists, what is most often left out is we train lots of scientists that we then force to return home, where they become competitors to America.
The origin of the student visa versus work visa problem we now face was a cultural mythology that was created, stating that companies would somehow pay foreign STEM graduates less, in defiance of state laws, federal laws, and ethics, unless they were forced to hire U.S. citizens. Because of that, union lobbyists got the American work visa process tightened up, in the belief that it would force American companies to hire people born in the US. Instead, businesses followed the work force back to Asia.
Researchers from Imperial College London and the University of Barcelona have used data from astronomical surveys to measure a standard distance that is central to our understanding of the expansion of the universe, a much more accurate method than calculations related to general relativity.
The new study is the first to measure it using observed data. A standard ruler is an object which consistently has the same physical size so that a comparison of its actual size to its size in the sky will provide a measurement of its distance to earth. Previously the size of this standard ruler has only been predicted from hypothetical models that rely on general relativity to explain gravity at large scales.
A new study by political science scholars has found one reason why women are less likely to run for political office - they will volunteer to lead but don't like competing to do so.
Prior claims have been that more women lack the confidence to seek and hold office so University of Pittsburgh associate Professors of Political Science Kristin Kanthak and Jonathan Woon enlisted 350 undergraduate college students to participate in laboratory experiments which Kanthak said appeared to show women are more "election averse" than men.
It is often said that the middle of the road is the worst place to drive, yet centrists pride themselves on always arguing the opposite of whatever the conversation is. They believe we should split the difference on all issues, though the actual functioning of the United Nations should have put a stake into the heart of that political vampire by now.
It turns out centrists are endangering their health in other ways, according to BMJ's annual Christmas issue, because by 'sitting on the fence' they are likely to be fatter than commies - especially Trotzkyites, who are always springing from political fad to political fad - and neo-Nazis too.
Why did the earliest farmers in the Fertile Crescent, an arc of land in western Asia from the Mediterranean Sea to the Persian Gulf, domesticate some cereal crops 10,000 years ago and not others?
