A Kiwi father-son duo has captured 3D colour X-rays of the human body based on a technology developed at CERN. The new scanner developed by the radio-logist son, Anthony Butler, and his physicist father, Phil, may eventually help diagnose cancers and blood diseases more accurately and without invasive surgery. The device was adapted from a pixel-detecting tool that physicists use for particle tracking at the Large Had-ron Collider (LHC) at CERN.

Placebo Peace

The recent ORBITA trial on the efficacy of angioplasty ("Stent dent", published on May 28) threw up a surprising finding; people who were treated with a sham procedure showed as much improvement as those who had angioplasty.

When a reddish cigar-shaped rock came spinning through the solar system last October, scientists could not figure out what it was. It didn't have a comet's tail so it must be an asteroid. Later studies have, however, shown that the Oumuamua is indeed a comet but with an invisible tail. Like all comets, the gases in its tail fired its exit from the solar system.

By combining data from NASA's Hubble Space Telescope and the European Southern Observatory's Very Large Telescope, astronomers have shown that gravity in this galaxy behaves as predicted by Albert Einstein's general theory of relativity. While the theory has passed a series of tests within the solar system, there have been no precise tests of it on large astronomical scales.

The magic of absolute zero

What would happen if you froze a flower to near absolute zero temperature - that is -273° Celsius? It would disintegrate. A banana cooled to that temperature would become rock solid and could be used to hammer a nail into a piece of wood. Nobel laureate Wolfgang Ketterle demonstrated these fascinating features of ultracold matter at a public lecture in Calcutta to commemorate the 125th anniversary of physicist Satyendranath Bose.
