Alternative practioners advise contrary to government policy but doctors don't advise at all

A study published in the September 14 issue of the British Medical Journal asked chiropractors, homeopaths and general practitioners for advice on immunisation for a child. 40% of homeopaths and 19% of chiropractors advised against immunisation for measles, mumps and rubella, contrary to government guidelines. However, of the 111 general practitioners contacted, not a single one responded!

There are many ways to interpret this data and conclusions that can be drawn. One possibility is that doctors shouldn't blame anybody but themselves for patients going to alternative practitioners if they are the only ones giving advice.

Protons and neutrons: a simpler picture

Protons and neutrons can be thought of as cloudy bags each with three quarks bouncing around inside, according to a new model in nuclear physics. The model allows many properties of nucleons (protons and neutrons) to be calculated far more easily than usual. Interestingly, the model resembles century-old ideas of what atoms looked like, when the “plum pudding” model pictured atoms as a uniform pudding with lumps of electrons inside. The “light front cloudy bag” model treats nucleons as three quarks, the most fundamental particles known, tied to each other and surrounded by a cloud of pions.
