It has long been well established that fingerprints can be used to identify people or help convict them of crimes. Things have gone a lot further now: fingerprints can be used to show that a suspect is a smoker, takes drugs, or has handled explosives, among other things. In the journal Angewandte Chemie, Pompi Hazarika and David Russell describe the noteworthy progress that has recently been made.

Applause spreads linearly, like a disease. The amount of time an individual feels like clapping is a factor, but not nearly as much as peer pressure.
This is interesting, how peer pressure can factor into little things. Would be good to see what makes the brain do these things and what chemical reactions occure.

Here’s another reason to love cicadas: A new study has found that tiny structures on cicada wings can kill bacteria through physical and not chemical means.
Interesting, could lead to some very important discoveries in future
Antibiotic resistance is nothing new; it is a very real threat in the world today. Bacteria are mutating and resisting our best tools at a rate that modern scientists can't keep up with. They say you learn something new everyday, and this was something I had no idea about until now! I flocked to this article because it is definitely an interesting concept. What is even cooler is the fact that a cicada's wings are able to kill gram-negative bacteria (gram-positive aren't affected), such as E. coli, through physical means and not chemical. This means the bacteria are unlikely to become resistant to the affects! Just imagine the ways scientists can utilize this!
This article, while not a scientific report, references the study done by scientists and provides links to it, therefore making the article a reliable source of information.

Simulations show that you can learn the meaning of words rapidly if you assume that every object has only one word associated with it.
This helps greatly with language students here at rhodes. Find out what is the difference between this learning style and the ordinary ones and what ordinary language learning styles are.

I saw this a while ago and forgot about it. It is not a method towards perfect language learning but it is a route to sufficient language learning.

Arithmetic division guides plants' use of energy at night.
As if making food from light were not impressive enough, it may be time to add another advanced skill to the botanical repertoire: the ability to perform — at least at the molecular level — arithmetic division.
This is an interesting science piece. You can research how this happens and whether research is going into learning how to replicate this in other objets.

The future of Facebook in our lives seems long-term. Facebook reports 1.11 billion monthly active users as of March 2013. That’s a lot of information being passed back and forth, a lot to absorb and respond to, and a lot to curate. As such, more people may find themselves taking a break from daily engagement with the site—sometimes you just need a break from Candy Crush Saga requests.

North Carolina State University researchers are using video game technology to remotely control cockroaches on autopilot, with a computer steering the cockroach through a controlled environment. The researchers are using the technology to track how roaches respond to the remote control, with the goal of developing ways that roaches on autopilot can be used to map dynamic environments – such as collapsed buildings.
