An Implantable Biosensor Could Alert Doctors to Signs of Disease

silk biosensor

A biosensor made from silk and gold can pick up tiny signals from proteins and chemicals in the body.

Silk and gold, usually a pairing for the runways of Milan, are now the main ingredients for a new kind of implantable biosensor. Researchers at Tufts University have crafted a small antenna from liquid silk and micropatterned gold. The antenna is designed to spot specific proteins and chemicals in the body, and alert doctors wirelessly to signs of disease. Scientists say the implant could someday help patients with diabetes track their glucose levels without having to test themselves daily.

Californian’s Volunteer DNA for Largest Human Genome Study Ever Attempted

SFGENOME

Samples have been donated by thousands of Kaiser members.

Still in fine fettle at the age of 87, Ruth Young, a retired Oakland school nurse, jumped at the chance, she said, to “spit for the cause.”  Mrs. Young is one of more than 130,000 members of Kaiser Permanente in Northern California who have volunteered to have their DNA scanned by robotic, high-speed gene-reading machines as part of the largest human genome study of its kind ever attempted.

A baby is born every hour in China with syphilis.

There is a baby born every hour  in China with syphilis, as the world’s fastest-growing epidemic of the disease is fueled by men with new money from the nation’s booming economy, researchers say.The easy-to-cure bacterial infection, which was nearly wiped out in China five decades ago, is now the most commonly reported sexually transmitted disease in its largest city, Shanghai.

Carrying extra pounds may not look attractive from the outside, but it’s been difficult to understand precisely the havoc it wreaks on your insides – until now.  Here, in a pair of astonishing pictures, we can see exactly what being overweight does to the organs, bones and muscles. These images of two women were taken by a magnetic resonance imaging (MRIRI) scanner and reveal in horrifying detail the obesity effect.

How the new designer babies are made.

Dozens of human embryos with three parents have been created by British scientists, ushering in an era of designer babies.  The embryos – which effectively have two mothers and one father – have been genetically engineered to be free from incurable muscle, brain, heart and digestive illnesses, some of which kill within hours of being born.

Breastfeeding could save lives

The lives of nearly 900 babies would be saved each year, along with billions of dollars, if 90% of U.S. women breast-fed their babies for the first six months of life, a cost analysis says. Those startling results, published online Monday in the journal Pediatrics, are only an estimate. But several experts who reviewed the analysis said the methods and conclusions seem sound.

Obese patients wash their plates after lunch at the Aimin Fat Reduction Hospital in Tianjin, China.  China now faces a whole new problem: the world’s biggest diabetes epidemic.

After working overtime to catch up to life in the West, China now faces a whole new problem: the world’s biggest diabetes epidemic. One in 10 Chinese adults already have the disease and another 16% are on the verge of developing it, according to a new study. The finding nearly equals the U.S. rate of 11% and surpasses other Western nations, including Germany and Canada.

James Harrison

Thank you Mr. baby saver!

An Australian man who has been donating his extremely rare kind of blood for 56 years has saved the lives of more than two million babies.

James Harrison, 74, has an antibody in his plasma that stops babies dying from Rhesus disease, a form of severe anaemia.

He has enabled countless mothers to give birth to healthy babies, including his own daughter, Tracey, who had a healthy son thanks to her father’s blood.

Mr Harrison has been giving blood every few weeks since he was 18 years old and has now racked up a total of 984 donations.
