A team of British scientists are developing plans for a spacecraft that could stop large asteroids from destroying the Earth.
The 10 tonne “gravity tractor” would deflect any orbiting rocks years before any potential collision could happen.
The device, which would rely on the force of gravity, is being developed by Stevenage space company, EADS Astrium.
However the idea is still in its early stages and the company admits a prototype has not yet been made.
What bugs me is the complete lack of comprehension of the quality of mercy that seems to have crept over the US political class this century.
Even if Al Megrahi is a mass-murderer, the fact remains that he is dying. It is long-standing policy in Scotland to exercise the prerogative of mercy when possible; in general, if an imprisoned criminal is terminally ill, a request for release (for hospice care, basically) is usually granted unless they are believed to be a danger to the public.
That’s because the justice system isn’t solely about punishment. It’s about respect for the greater good of society, which is better served by rehabilitation and reconcilliation than by revenge. We do not make ourselves better people by exercising a gruesome revenge on the bodies of our vanquished foes. Kenny MacAskill, the Justice Minister, did exactly the right thing in sending Al Megrahi home to die.
My eldest daughter had a rough first week. Born after 22 hours of hard labor, her pink skin proceeded to turn an alarming shade of yellow on the second day of her life. It was a bad case of jaundice. She would need to be placed in an incubator, whose ultraviolet light would hopefully clear up the condition. If not, a transfusion would be required. My exhausted wife and I watched in numb horror as our child was encased in the clear plastic box that was to become her crib for the next seven days. What we had hoped would be a straightforward delivery had turned into a nightmare.
Did humans evolve to be religious and believe in God? In the most general sense, yes we did. Here’s what happened.
Long long ago, in an environment far far away from the modern world, humans evolved to find meaningful causal patterns in nature to make sense of the world, and infuse many of those patterns with intentional agency, some of which became animistic spirits and powerful gods. And as a social primate species we also evolved social organizations designed to promote group cohesiveness and enforce moral rules.

People with conditions such as HIV, TB and malaria should not rely on homeopathic treatments, the World Health Organization has warned.
It was responding to calls from young researchers who fear the promotion of homeopathy in the developing world could put people’s lives at risk.
The group Voice of Young Science Network has written to health ministers to set out the WHO view.
WHO TB experts said homeopathy had “no place” in treatment of the disease.
To be fair, homeopathy has no place in the treatment of <em>any</em> disease
Young people’s attitudes to music may be too complicated and fast-changing to measure, says Bill Thompson
Hacking your iPhone to run unofficial, third-party apps may seem unnecessary since Apple hosts its own App Store. But the corporation’s recently enforced prohibitions on some apps, such as the banning of Google Voice, are reviving the incentive for customers to jailbreak their iPhones once again.
As geek parents, we often have rosy colored notions about our children growing up. We actually want them to be geeks. From the earliest of ages we dress them in WoW gear, teach them to quote Star Wars and wonder when is too early to start reading The Hobbit. We nurture them in the way of the Geek, hoping that, when the time comes for them to choose their path, they won’t stray far.
But being a geek kid isn’t easy; and being a geek girl might even be harder. Here are some things to keep in mind if you are raising a geek girl that might help her–and you–get through the school years.
