No more seafood by 2050?

There may be no more commercial fish stocks left in the sea by 2050, according to a new study cataloguing the global collapse of marine ecosystems.

It blames not just over-fishing, but also mankind’s wider attack on the health of ocean ecosystems, for instance from pollution. “Unless we fundamentally change the way we manage all the ocean species together, as working eco-systems, then this century is the last century of wild food,” says Steve Palumbi at Stanford University in California, US, who carried out the four-year investigation with colleagues.

Uniquely, it combines historical data on fish catches, some of it going back a thousand years, with analysis of marine ecosystems and experiments to bring marine life back to protected areas.  Continue reading No more seafood by 2050?

Finding the 'God' particle could destroy the universe, warns Stephen Hawking

The elusive ‘God particle’ discovered by scientists in 2012 has the potential to destroy the universe, Professor Stephen Hawking has warned.

At very high energy levels, the Higgs boson could cause space and time suddenly collapse – and ‘we wouldn’t see it coming’, the former Cambridge professor of mathematics says.

The God particle, which gives shape and size to everything that exists, could cause a ‘catastrophic vacuum delay’ if scientists were to put it under extreme stress. 

A disaster like this is very unlikely for the time being as physicists do not have a particle accelerator large enough create such an experiment, but Prof Hawking’s comments have excited scientists, the Sunday Times reported.  Continue reading Finding the 'God' particle could destroy the universe, warns Stephen Hawking
