It is not the critic who counts: not the man who points out how the strong man stumbles or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly, who errs and comes up short again and again, because there is no effort without error or shortcoming, but who knows the great enthusiasms, the great devotions, who spends himself for a worthy cause; who, at the best, knows, in the end, the triumph of high achievement, and who, at the worst, if he fails, at least he fails while daring greatly, so that his place shall never be with those cold and timid souls who knew neither victory nor defeat.
- Theodore Roosevelt
I hope that no one will claim to know the final answers; no good comes from prophets. But even when acknowledging our falibility, we must nevertheless continue to think about these matters and give the advice to others that intellect and conscience dictate. And let God be our judge, as our grandparents used to say. - Sakharov

Satellite quantum communication circles closer
A new quantum protocol is the first that promises to work independently of the orientation of spin on pairs of entangled photons shared between a sender and receiver, which will prove vital if quantum communications are ever to be sent via satellites (a spinning satellite’s sense of up and down changes over time, making it [...]

Reliable Dictation, Down to a ‘T’
The accuracy of the new Dragon NaturallySpeaking for Windows speech-recognition program is so good that you no longer have to begin by reading a four-minute training text, writer David Pogue has found.

Helping Joints Regrow Themselves
Biomedical engineers at Columbia University Medical Center have implanted a joint-shaped scaffold infused with a growth factor protein that allowed rabbits to begin using their injured forelimbs again in one month.
At two months, the animals moved almost as well as similarly aged healthy rabbits. The study is the first to show that an entire joint [...]

The Science Of ‘Inception’
Real-life technologies can perform some of the mind-reading tricks shown in the new film Inception, in which people are able to observe and participate in someone’s dreams.
Jack Gallant, a neuroscientist at the University of California, Berkeley shows people images and movies while taking a functional magnetic resonance imaging (fMRI) scan of their brains. He uses [...]

Using exploding nanoparticles to insert DNA and proteins into cells
Chemical “nanoblasts” activated by bursts of laser light can punch tiny holes in the protective membranes of cells just long enough to admit therapeutic small molecules, proteins and DNA directly into living cells, Georgia Institute of Technology.researchers have discovered.
“One of the most significant uses for this technology could be for gene-based therapies, which offer great promise [...]

Aging and longevity tied to specific brain region in mice
Researchers watched two groups of mice, both nearing the end of a two-day fast. One group was quietly huddled together, but the other group was active and alert. The difference? The second set of mice had been engineered so their brains produced more SIRT1, a protein known to play a role in aging and longevity.
“This [...]

Big Bang Abandoned in New Model of the Universe
A new cosmology successfully explains the accelerating expansion of the universe without dark energy; but only if the universe has no beginning and no end.
Wun-Yi Shu at the National Tsing Hua University in Taiwan has developed an innovative new description of the Universe in which time and space are not independent entities but can be [...]
