A Prosthesis For Speech


"For more than eight years, Erik Ramsey has been trapped in his own body. At 16, Ramsey suffered a brain-stem injury after a car crash, leaving him with a condition known as 'locked-in' syndrome. Unlike other forms of paralysis, locked-in patients can still feel sensation, but they cannot move on their own, and they are unable to control the complex vocal muscles required to speak. In Ramsey's case, his eyes are his only means of communication: skyward for yes, downward for no.

Now researchers at Boston University are developing brain-reading computer software that in essence translates thoughts into speech. Combined with a speech synthesizer, such brain-machine interfacing technology has enabled Ramsey to vocalize vowels in real time--a huge step toward recovering full speech for Ramsey and other patients with paralyzing speech disorders. The researchers are presenting their work at the annual Acoustical Society of America meeting in Paris this week..."

Radioactive Fungi


"...Sitting at the centre of the exclusion zone, the damaged reactor unit is encased in a steel and cement sarcophagus. It's a deathly tomb that plays host to about 200 tonnes of melted radioactive fuel, and is swarming with radioactive dust.

But it's also the abode of some very hardy fungi which researchers believe aren't just tolerating the severe radiation, but actually harnessing its energy to thrive.

'Our findings suggest that [the fungi] can capture the energy from radiation and transform it into other forms of energy that can be used for growth,' said microbiologist Arturo Casadevall from the Albert Einstein College of Medicine at Yeshiva University in New York, USA..."
