I wouldn't be surprised if the young fellow who took the time-lapse is working on such a thing ... but I'll ask him next time I see him and suggest this might make a nifty science project.

A report on the Beeb's Science & Environment page suggests that spacetime is smoother than some theories predict.

The comment I particularly like is

Studying the detailed maps it has provided is not unlike entering a kitchen and figuring out how the first steps of dinner were prepared based on the distribution of leftover heat.

NYT has a piece on the same subject:

Tending the Body’s Microbial Garden: For a century, doctors have waged war against bacteria, using antibiotics as their weapons. But that relationship is changing as scientists become more familiar with the 100 trillion microbes that call us home — collectively known as the microbiome.

“I would like to lose the language of warfare,” said Julie Segre, a senior investigator at the National Human Genome Research Institute. “It does a disservice to all the bacteria that have co-evolved with us and are maintaining the health of our bodies.”

This new approach to health is known as medical ecology. Rather than conducting indiscriminate slaughter, Dr. Segre and like-minded scientists want to be microbial wildlife managers.

No one wants to abandon antibiotics outright. But by nurturing the invisible ecosystem in and on our bodies, doctors may be able to find other ways to fight infectious diseases, and with less harmful side effects. Tending the microbiome may also help in the treatment of disorders that may not seem to have anything to do with bacteria, including obesity and diabetes.

Solar Flares Fire Double Sun Storm at Earth

The M-class solar flares set off two coronal mass ejections (CMEs) that erupted from the sun on last Wednesday and Thursday (June 13 and June 14).

Looking at that exhibit, he mentions Kruggel & Emden 2005, and Kempe & Fröhlich 2011. Some of the graphics in the exhibit seem to match graphics in Impact of collision models on particle transport in open channel flow

I mean yes, those kids are definitely smarter than the reporters. The reporters should stick to the they know best - whose dress was the worst in a red carpet reception, or what size of rats are running in the New York subway.

Just like we always knew.

Nuff of these oneliners already.

Else your post rate may approach mine (or SM's for that matter).
Then you'll be really deep in da doodoo

8.12 ppd, not including this one. (Also I just got 120 seconded, from the post about primality tests of cofactors.)

High time you were awarded a "useless posts" thread of your own.
