And Baby Makes Five

Hadrons are heavy nuclear particles composed of either 2 quarks called a meson, or three quarks called a baryon.  Recent work at the Large Hadron Collider (LHC) at CERN has led to the discovery of five new variants of the Omega-C baryon, which are composed of two strange and one charm quarks.

You can read about this important discovery here and here.  To learn how the LHC works, click on the video above.


Strokes and Spiders

A report out of Australia confirms that a harmless ingredient called Hi1a in the otherwise deadly venom of the funnel spider may reduce neuron deaths in strokes induced in rats by upwards of 80% if given within two hours and 65% if given within eight hours.

Human trials are expected to start within two years.


Moderate Drinking

The British Medical Journal (BMJ) reports that after studying nearly two million originally heart healthy UK residents, there is significant evidence to indicate that moderate drinking of alcohol reduces the onset of certain cardiovascular conditions, notably angina, heart failure and ischaemic stroke.

You can read about the study here and here

Moderate drinking is defined as consuming about 14 units of alcohol per week.

International Cloud Atlas

The World Meteorological Organization – for the first time in 30 years – has updated its International Cloud Atlas to much fanfare, adding 12 new classifications of clouds.

You can visit the Cloud Atlas, or make submissions of your own from your phone camera.

Much to my surprise, the PBS program NOVA has put together interactive labs for various important scientific subjects, including a Cloud Lab, which you can explore here.
