Science Glance
Scientists at Princeton have built a tiny microwave laser (a "maser") the size of a rice grain. The laser is made of artificial atoms called quantum dots -- miniature bits of semiconductor material.
"It is basically as small as you can go with these single-electron devices," lead study author Jason Petta, an associate professor of physics at Princeton, said in a recent press release.

Space station crew moved after gas leak fears
Crew members were evacuated from a US segment of the International Space Station after an ammonia leak was suspected.
But Nasa officials now says a sensor problem probably created the false impression of leaking coolant.
The Russian space agency emphasised that the crew members had not been in any danger.
SpaceX Suffers Hard Landing on Barge
Space rocketeers at SpaceX just missed a catch on Saturday, failing in a bold first attempt to recycle a used rocket engine by landing it on a ship in the Atlantic Ocean.
"Close, but no cigar this time. Bodes well for the future," said SpaceX chief Elon Musk on Twitter. The touchdown would have been a first for ocean landings.
The landing attempt was made shortly after a flawless 4:47 a.m. (EST) launch of the resupply spacecraft from the Cape Canaveral Air Force Station in Florida.
Researchers Create Artificial Organs On Microchips
Great balls of cells! Scientists are developing mock human organs that can fit in the palm of your hand.
These organs-on-a-chip are designed to test drugs and help understand the basics of how organs function when they are healthy and when they are diseased.
For instance, you have your gut-on-a-chip being developed at the Johns Hopkins School of Medicine. It's a high-tech approach to dealing with a scourge of the low-tech world.
Spectacular real vigin births
Thelma the snake confused then astounded her keepers.
This 6m long (20 ft) python had spent four years alone in Louisville zoo in the US, without ever having met a male of her species. But, somehow, she laid over 61 eggs, producing six healthy babies. Perhaps she’d managed to secretively mate with a male many years before, and store his sperm all this time?
Genetic tests soon revealed the answer.
Internet privacy will be mostly gone by 2025, according to experts
According to a new Pew Research Center report, most experts think internet privacy is on its way out.
The research center asked over 2,500 technology experts if politicians and technology innovators would create a trusted privacy-rights infrastructure by 2025, what is most likely to happen by then and the future of privacy in a broader sense.
55 percent of respondents said a "trusted privacy-rights infrastructure" would not exist by 2025.
These robots are ready to serve you
A hardware store in San Jose has a new star employee. It can speak English and Spanish, recognise any part at sight, and knows what the shop has in stock on a second by second basis.
And it's also a robot. OSHbot, as it is called, measures roughly 5ft, and boasts a 3D scanner and touchscreen. "It's not just robots for robots' sake, or a marketing gimmick," insists Kyl Nel, executive director of Lowe's Innovation Labs.
Lowe's is an American DIY chain, and the robot's ultimate employer.
