A specific antioxidant supplement containing N-Acetylcysteine, or NAC may be an effective therapy for some features of autism, according to a pilot trial from the Stanford University School of Medicine and Lucile Packard Children's Hospital that involved 31 children with the disorder.

You've read a lot about 'invisibility' over the last few years.  Mathematicians and scientists have been working on various devices that enable invisibility cloaks which shield small objects from detection by microwaves or sound waves.

Stem cell research is very dynamic with research trends, focus, and approaches evolving rapidly - but increased government restrictions on the private sector have led to a steep decline in venture capital, which threatens to slow the pace of research and development. 

New analysis from Frost&Sullivan, 'Strategic Analysis of the European Stem Cell Research Tools Market', finds that the market earned revenues of $148.4 million in 2011 and estimates this could reach $322 million in 2017. The segments covered include: bio-imaging and microscopy, cell biology tools, immunochemical, molecular biology tools, and protein biochemistry tools.

'The cloud' is so cliché Microsoft even has housewives using it in commercials.  All it basically means is that you can have a new way for your data to be hacked and stolen.  Unless the company storing it goes out of business and you made no backups.  Plus, that's not really a cloud, it's stored in a solid medium, it just happens to be outside your house.

But true cloud storage is on the horizon. 

Light signals have been stored as patterns in a room-temperature atomic vapor by scientists at the Joint Quantum Institute. They stored two letters of the alphabet in a cell filled with rubidium (Rb) atoms. 

June 5, 2012 you get to share a communal experience with scientists from hundreds of years ago.  No, I don't mean Calculus, I mean one of the rarest and more interesting recurring events science has been able to witness since the invention of the telescope - a transit of Venus.

You may not have heard of it but you know of it if you ever wondered how astronomers were able to calculate how far away the Sun is from Earth - the basis of the Astronomical Unit (AU) that is eponymous today.

Today's primer: orbital mechanics, or how we have to manuever to catch debris.  There's a lot of debris in low earth orbit, ranging from paint chips and spare bolts to a heavy toolbox up through entirely dead satellites.  It's tracked, it's plentiful, it was even featured in Wall-E.  How is it a satellite in orbit runs into debris?

Measuring the value and the impact of a scientist on her field of research using as data her scientific papers, the number of citations these papers got, and the prestige of the scientific journals where these were published is no easy matter.

Grading Researchers: The H-Index

There is a large body of literature on how best to account for all these factors together: the discipline is called "scientometrics". Of course, the goal is to summarize the productivity of a scholar in a single number; possibly one with at most double digits, since decision-makers who hire or fund are usually incapable of handling more complex data. One notable attempt is the Hirsch Index, proposed in 2005 by a physicist, Jorge Hirsch.
