Callinectes sapidus, the blue crab or Atlantic blue crab, is a species of crab native to the waters of the western Atlantic Ocean and the Gulf of Mexico, and introduced internationally. They may grow to a carapace width of 230 mm (9.1 in). Female blue crabs mate only once in their lifetimes. C. sapidus is of significant culinary and economic importance in the United States, particularly in Louisiana and in the Chesapeake Bay. It is the Maryland state crustacean and is the state’s largest commercial fishery.
This is an important crab to us Cajun folk.

Scientists from MIT Developed a Trillion frames per second slow motion camera that can show light moving through a bottle. Ramesh Raskar presents femto-photography - For comparison, the imaging of a bullet captured at this many frames per second would last a year as explained in thepresentation by Professor Ramesh Raskar of MIT.
^ what you have witnessed above is light travelling in slow motion.
OOOOOOOOOH MY GOD
The worst Ebola outbreak in history has put a number of countries in West Africa in lockdown, led to the deaths of nearly 700 people since February and brought new reports of doctors, including Americans, contracting the virus they are attempting to contain. The situation is undeniably scary. Here’s what you need to know.
What is Ebola?
Ebola viral disease is a highly infectious illness with fatality rates up to 90 percent, according to the U.N. World Health Organization. Symptoms initially include a sudden fever as well as joint and muscle aches and then typically progress to vomiting, diarrhea and, in some cases, internal and external bleeding — you can see a full, grim description of symptoms compiled by the Centers for Disease Control and Prevention (CDC) here.
The virus spreads through contact with bodily fluids of someone who is infected. Reports of human infections usually first emerge in remote areas that are in proximity to tropical rain forests, where humans can come into contact with animals such as chimpanzees, gorillas and forest antelope. The consumption of bush meat is often a precursor to such outbreaks. The WHO says fruit bats are probably the natural host for the virus.
How do we terraform Venus?
It might be possible to terraform Venus some day, when our technology gets good enough. The challenges for Venus are totally different than for Mars. How will we need to fix Venus?
This planet has been the center of corny nerd fantasies and awful behavioral gender oversimplifications from days of yore.
There are many real reasons to admire Venus from afar, but my favorite, much like Mars, is the potential to turn it into a vacation spot and haven for mad science planetary engineering. Venus is a virtual twin of Earth. It has a solid surface and very similar gravity to Earth.
International Space Station astronaut Alexander Gerst has posted his “saddest photo yet.” From all the way up in the thermosphere, ISS personnel orbiting 200 miles over the Middle East can see bombs and missiles exploding in Gaza and Israel as the two sides go to war.
How does Tylenol work? The truth is, we don’t know…
Acetaminophen, the active ingredient in Tylenol™, is one of the most popular pain relievers in the world, selling more than 27 billion doses in 2009 alone. It can reduce fevers, eliminate aches and pains and relieve cough and cold symptoms. But how does it work? The truth is, no one knows exactly. This week, Reactions examines the theories about the popular pill.

"Maybe we’re on Mars because of the magnificent science that can be done there - the gates of the wonder world are opening in our time. Maybe we’re on Mars because we have to be, because there’s a deep nomadic impulse built into us by the evolutionary process, we come after all, from hunter gatherers, and for 99.9% of our tenure on Earth we’ve been wanderers. And, the next place to wander to, is Mars. But whatever the reason you’re on Mars is, I’m glad you’re there. And I wish I was with you.”
— Carl Sagan
Excellent advice from (arguably) the coolest physicist to have ever lived, Richard Feynman: you don’t have to be a genius to want to study science, you just have to work hard!
Edit: just realized the initial quote reads: “ordinary” rather than “normal” — our apologies for the screw up!
In March 2003, Saturn’s rings were at maximum tilt toward Earth, a special event occurring every 15 years. With the rings fully tilted, astronomers get the best views of the planet’s Southern Hemisphere. They took advantage of the rings’ unique alignment by using Hubble to capture some stunning images.
