The Higgs boson particle – digested
The secret of life and the universe, explained by our science editor

An experimental result in the search for the Higgs boson particle, released by Cern.

In the aftermath of the big bang that flung the universe into existence 13.82bn years ago, the forces of nature were one. But as the universe expanded and cooled, they separated out into the four seen today. The electromagnetic force, which is carried by photons, allows you to see, and stops you falling through your chair.

The strong force holds atomic nuclei together. The weak force goes to work in the sun and helps to make it shine. Then there is gravity, which is not really a force at all, but that is for another time.

One trillionth of a second after the big bang, an invisible field that spread throughout space switched on. This Higgs field wrenched two intertwined forces apart – the weak force and the electromagnetic force. How? By making the particles that carry the weak force heavy, while leaving the photon weightless.

The weak force travels less than the width of an atom, but the electromagnetic force ranges over an infinite distance.

The Higgs field gives mass to other particles too, such as quarks and electrons, the building blocks of atoms. The Higgs boson comes with the field, a subatomic smoking gun that proves the field is there.

Diamond to shine light on infections

Diamond to shine light on infections http://www.bbc.co.uk/news/science-environment-21481223

The UK’s national synchrotron facility – the Diamond Light Source near Oxford – is to become a world centre for studying the structure of viruses and bacteria that cause serious disease.

Diamond uses intense X-rays to reveal the molecular and atomic make-up of objects and materials.

It will now use this capability to image Containment Level 3 pathogens.

These are responsible for illnesses such as Aids, hepatitis and some types of flu.

Level 3 is one step down from the most dangerous types of infectious agent, such as Ebola, which can only be handled in the most secure government facilities.

“Viruses, as you know, are sort of tiny nanomachines and you can’t see them in a normal microscope.

“But with the crystallography and X-ray techniques we use, we are able to get about 10,000 times the resolution of the normal light microscope,” explained Dave Stuart, the life sciences director at Diamond and a professor of structural biology at Oxford University.

“This takes us from the regime of not being able to see them to being able to see individual atoms.

“And if we can look at ‘live’ viruses and get an atomic-level description of them, it opens up the possibility of using modern drug-design techniques to produce new pharmaceuticals.”

Prof Stuart was speaking in Boston at the annual meeting for the American Association for the Advancement of Science (AAAS).

Has Dark Matter Finally Been Found? Big News Coming Soon. http://goo.gl/mag/6pMDilc

If we can work this out then we can start to think about the end of the universe and also what is going to happen in the meantime  🙁
