Graphene ‘stimulation’ could selectively kill off cancer cells

Posted by in categories: biotech/medical, computing, mobile phones

A chance lab discovery is opening up the possibility for wide-scale improvements in drug screening, application of selective painkillers, and selectively nuking cancer cells. The mystery material? Graphene, a semi-metal that’s composed of a single layer of carbon atoms. It’s already being used to make flexible OLED displays and reduce the energy costs of desalination, but its potential benefits for the medical field look promising too.

It began with a theory — scientists at the University of California knew graphene could convert light into electricity, and wondered whether that electricity had the capacity to stimulate human cells. Graphene is extremely sensitive to light (1,000 times more than traditional digital cameras and smartphones) and after experimenting with different light intensities, Alex Savchenko and his team discovered that cells could indeed be stimulated via optical graphene stimulation.

“I was looking at the microscope’s computer screen and I’m turning the knob for light intensity and I see the cells start beating faster,” he said. “I showed that to our grad students and they were yelling and jumping and asking if they could turn the knob. We had never seen this possibility of controlling cell contraction.”

Achieving scalability in quantum computing

Posted by in categories: computing, quantum physics

While a variety of quantum systems exist today, many are unable to scale to solve some of the world’s most challenging problems. Explaining the real-world obstacles of building a quantum system that scales, this post explores how Microsoft addresses these challenges through a topological qubit.

Almost everything you know about e-waste is wrong

Posted by in categories: computing, economics, health

Many of us think we know what electronic waste is because we wonder what to do with devices we no longer want or need.

It’s the old cellphone and its charger stuffed in the drawer.

It’s that old laptop, monitor or printer packed behind the door or in the basement.

What is the Singularity?

Posted by in categories: computing, internet, physics, singularity, transhumanism, virtual reality

Not everyone is convinced. Critics point out that one of the points of exponential growth is that it cannot carry on forever. After a 50-year run, Moore’s Law is stuttering. Singularitarians retort that the laws of physics define a limit to how much computation you can cram into a given amount of matter, and that humans are nowhere near that limit. Even if Moore’s Law slows, that merely postpones the great day rather than preventing it. Others say the Singularity is just reli…gion in new clothes, reheated millenarianism with transistors and Wi-Fi instead of beards and thunderbolts. (One early proponent of Singularitarian and transhumanist ideas was Nikolai Federov, a Russian philosopher born in 1829 who was interested in resurrecting the dead through scientific means rather than divine ones.) And those virtual-reality utopias do look an awful lot like heaven. Perhaps the best way to summarise the Singularity comes from the title of a book published in 2012: the Rapture of the Nerds.


And will it lead to the extermination of all humans?
