Samsung Has Patented An Augmented Reality Smart-Contact Lens

Sunday, April 17th, 2016

Google Glass perhaps didn’t receive the earth-shattering response the company – and world – had expected. However, a proposal that Samsung appears to have in the works could be the augmented reality wearable tech everybody is holding out for.

Samsung has filed a patent in South Korea for a smart contact lens fitted with a camera and image display. In addition, it will feature sensors that can control certain functions simply by blinking. The concept design requires an accompanying smartphone to do some of the leg-work, which would be wirelessly connected to the lenses.

 

A 65-year-old mother of 13 is pregnant with quadruplets

Monday, April 13th, 2015

The last time Annegret Raunigk gave birth, to her 13th child, she was 55 years old.

Now, the 65-year-old teacher from Germany is pregnant once again — this time with quadruplets conceived through in vitro fertilization, a German newspaper reported.

Critics have voiced concern that Raunigk purposefully sought out a high-risk pregnancy. “The 65-year-old body is definitely not designed to carry a pregnancy, not of one child and certainly not of quadruplets,” said Holger Stepan, head of obstetrics at the University of Leipzig

Pregnancies of women over the age of 45 are deemed high risk while “over 60 is naturally extreme.”

Raunigk could become the world’s oldest woman to give birth to quadruplets, but she wouldn’t be the oldest known woman to give birth.

Raunigk had her 13th child, Leila, in 2005. “I was surprised myself as the last baby wasn’t planned,” she said at the time, AFP reported. “I was told about it when I was 11 weeks pregnant.”

“At first, I only wanted one child,” she told Bild in 2005. “Not all were planned. But then things happen. I’m not a planner but rather spontaneous. And children keep me young.”

Raunigk, a Russian and English teacher nearing retirement, has children ranging in age from 9 to 44. She also has 7 garndchildren. She is expected to give birth to the quadruplets in two months, and AFP reports her pregnancy has been without any major complications so far.

A brief history of DNA Testing

Tuesday, June 23rd, 2009

brief history dna testing

As most any episode of CSI (= Les Experts) will tell you, DNA testing is a staple of modern crime investigations.

Since the advent of DNA testing in 1985, biological material (skin, hair, blood and other bodily fluids) has emerged as the most reliable physical evidence at a crime scene, particularly those involving sexual assaults. DNA, or deoxyribonucleic acid, contains the complex genetic blueprint that distinguishes each person. Forensic testing can determine if distinctive patterns in the genetic material found at a crime scene matches the DNA in a potential perpetrator with better than 99% accuracy.

As accuracy rises and costs drop, DNA analysis is becoming increasingly widespread. It’s familiar to daytime-TV fans as the leading method to determine paternity; do-it-yourself tests are now sold at drugstores in the USA.

Study finds tall people at top of wages ladder

Wednesday, May 20th, 2009

Tall people earn higher wages than their vertically-challenged counterparts while being obese does not mean a slimmed-down pay packet, according to a new study in Australia.

The researchers found a strong link between wages and height, particularly for men, with each additional 10 centimetres (four inches) of height adding three percent to hourly wages.
