Tuberculosis (TB)  is a contagious disease of the lungs and other organs caused by Mycobacterium tuberculosis (or M. tuberculosis) and which infects roughly a third of the world's population.  5-10% of those in the infected population become sick or infectious at some point during their lifetime. 

I have long told my more progressive brethren who have been happy about overarching judicial decisions they happened to like that activism is a double-edged sword.   Certainly it's reasonable to 'cross that bridge' when society gets to it, but until then the repercussions are substantial.

In the instance of an injunction on embryonic stem cell research being upheld, it's not evil Republicans sticking it to stem cell research, though I have long contended they never did by simply restricting the human embryonic stem cell kind anyway - that law was signed by Clinton.  Instead, it is a court and we have 50 solid years of aggressive judicial good works that has gone well beyond interpreting the Constitution, making it the most powerful branch of government.

NGC 300 is one of the closest and most prominent spiral galaxies in the southern skies,  about six million light-years away and bright enough it can be seen with binoculars. NGC 300 lies in the constellation of Sculptor with only a few bright stars, but is home to a collection of nearby galaxies that form the Sculptor Group, though recent distance measurements show that NGC 300 lies significantly closer to us than many of the other galaxies in the group and may be only loosely associated with them.

Compared to other galaxies, NGC 300 is remarkably normal, making it an ideal specimen for astronomers studying the structure and content of spiral galaxies such as our own.

Current battery design and implementation is not optimal, but it's cheap.  A new effort seeks to make conventional battery systems more standardized and increase interoperability of battery and charger parts, which creates energy waste, extra costs and operational inefficiencies.  But it's not for the casual user.

It's called the Intelligent Battery system and it also isn't cheap - the charger is about 20 percent more expensive than alternatives but the developers say the extra initial investment is recuperated in the medium and long term through prolonged battery life and better performance and the system provides real time information on the health and charge level of their batteries.

An important enzyme that acts in the nervous system may lead to new treatments for conditions such as Alzheimer's and Parkinson's disease.

Our cells contain a network of tubes known as microtubules that are made of protein and serve as tracks for the shuttling of materials from one part of the cell to another.   Microtubules in parts of neurons in the brain that send signals, for example, are loaded with chemical additions called acetylation marks. Microtubules in parts of neurons that receive signals, on the other hand, have few. 

Gossiping has benefits, according to research conducted by Dr. Jennifer Cole and Hannah Scrivener from Staffordshire University, who presented preliminary results at the British Psychological Society Social Psychology Section annual conference at the University of Winchester.

And praising someone in gossip may even lead to a short-term boost in gossipers' self-esteem.
