Cell division is central to life and the last stage, when two daughter cells split from each other, has fascinated scientists since the dawn of cellular biology.

The name given to this process by those early biologists, cytokinesis, translates as "cell movement" and captures the sense of a highly active and organized series of events. Studying the final step, when the dividing cell creates a furrow before cleaving in two, has been difficult.  How does the cell signal where the furrow should be?  

Though young people are pleased that the federal government has declared they are not actually adults until age 26 when it comes to having to pay bills, adults who remember being teenagers know that teens don't actually buy into that - they feel mature, especially when it comes to things they want to do.

It is no surprise that young people favor more liberal marijuana laws. In 2014, marijuana is just as cool as smoking cigarettes was in 1954. And like in 1954, proponents gloss over the obvious health risks while governments insist they should get the tax revenue because people will do it anyway.

More than 60 years after the last confirmed sighting, a strange deer with vampire-like fangs is roaming the rugged forested slopes of northeast Afghanistan, according to a research team which confirmed the species presence during recent surveys.

Most modern cryptographic schemes rely on complexity for security - they can be cracked, but that would take a prohibitively long time, even with enormous computational resources.

Information-theoretic security, in which even an adversary with unbounded computational power could extract no useful information from an encrypted message, is far too complicated to be practical. With the current White House administration engaged in an unprecedented level of domestic spying, there is a great deal of interest in privacy even the government can't crack.

To gain followers on Twitter, some supposed social media and SEO "experts" claim that a lot of volume and following a lot of people is the road to popularity. 

Not really. The most effective strategy is to already be famous. Due to its imbalanced structure, Stephen Hawking is going to get more followers than you because he is already famous. Once a person with a lot of followers notifies the public he is on Twitter, it takes off much faster than if his social media intern followed 100 people with a few dozen followers. Less popular users can compensate for this by increasing their activity and their tweets but the outcome is costly and inefficient. 

If you see a bat zooming toward you this evening, cover your hair. But if you do get bit, you will probably not the flu.

Halloween bats can be a little scary knowing they are not going to spread most viruses. A research project finds that influenza viruses carried by bats pose a low risk to humans.
