A study done by Stanford University School of Medicine and Stanford Hospital&Clinics suggests that the use of a dietary supplement after Roux-en-Y gastric bypass surgery can help obese patients to more quickly lose weight and to avoid deficiency of a critical B vitamin.

The cluster of stars surrounding a supermassive black hole after it has been ejected from a galaxy are a new kind of astronomical object, according to a paper published in Astrophysical Journal.

More importantly, the stars contain a 'fossil record' from the 'kicking' galaxy.

The phrase 'like herding cats' resonates with people for a reason; it's difficult to get them to do anything they don't already want to do.

But they have no problem getting humans to do their bidding, according to a report published in Current Biology, which shows that even biologists are concerned about future feline-human relations.

It seems crafty felines accelerate the filling of food dishes by sending a mixed signal: an urgent meowing coupled with an otherwise pleasant purr.  Humans find it annoying and difficult to ignore.   It's not April 1st or December so calibrate your belief accordingly. 

Researchers at Lawrence Berkeley National Lab and UC Berkeley say they have demonstrated a way to fabricate efficient solar cells from low-cost, flexible materials; optically active semiconductors in arrays of nanoscale pillars, each a single crystal, with dimensions measured in billionths of a meter. 

Want to live forever but starving is not for you?   A study published in Proceedings of the National Academy of Sciences may be more to your liking.

Sulfate gets all the attention but iron and manganese compounds may be important role in converting methane to carbon dioxide and eventually carbonates in the Earth's oceans, according to a team of researchers looking at anaerobic sediments.

Those same compounds may also have been key to methane reduction in the early, oxygenless days of the planet's atmosphere.  On the early Earth, where oxygen was absent from the atmosphere, sulfates were scarce.
