Scientists at The University of Manchester have created the world’s first ‘molecular robot’ that is capable of performing basic tasks including building other molecules. The tiny robots, which are a millionth of a millimetre in size, can be programmed to move and build molecular cargo, using a tiny robotic arm.
Each individual robot is capable of manipulating a single molecule and is made up of just 150 carbon, hydrogen, oxygen and nitrogen atoms. To put that size into context, a billion billion of these robots piled on top of each other would still only be the same size as a single grain of salt. The robots operate by carrying out chemical reactions in special solutions which can then be controlled and programmed by scientists to perform the basic tasks.
In the future such robots could be used for medical purposes, advanced manufacturing processes and even building molecular factories and assembly lines. The research will be published in Nature on Thursday 21st September.

In a mind-boggling world first, a team of biologists and security researchers have successfully infected a computer with a malicious program coded into a strand of DNA.
It sounds like science fiction, but I assure you it’s quite real — although you probably don’t have to worry about this particular threat vector any time soon. That said, the possibilities suggested by this project are equally fascinating and terrifying to contemplate.
The multidisciplinary team at the University of Washington isn’t out to make outlandish headlines, although it’s certainly done that. They were concerned that the security infrastructure around DNA transcription and analysis was inadequate, having found elementary vulnerabilities in open-source software used in labs around the world. Given the nature of the data usually being handled, this could be a serious problem going forward.

Summary: The Hygiene Hypothesis persuades people to consume parasitic worms as a way to treat chronic autoimmune disorders. As well, people eat tapeworms as a way to lose weight. Learn more about two closely related scientific beliefs called the “Hygiene Hypothesis” and the “Old Freinds Hypothesis.” Part 1 of a 2-part series. Cover photo: 3drenderings / Getty Images.
It’s difficult to believe, but thousands of people eat worms as a way to lose weight or cure diseases.
People don’t just eat worms on TV shows, like the Fear Factor. Some extreme dieters consume tapeworms as a way to lose weight. Another group of people ingests parasitic worms known as helminths to ward-off the debilitating symptoms of autoimmune diseases.

Summary: Helminthic therapy is the intentional consumption of parasites as a treatment for autoimmune disease. Out of the 7000 people who practice helminthic therapy each year, this report tells the story of a young woman who purchases black market worms and then treats herself at a high cost.

Would you eat worms to boost your overall health or cure what ails you?
Over 7,000 people intentionally self-infect with parasites, and the practice is growing in popularity.

Regular visits to the dentist are an important part of keeping your teeth healthy. But what if you could give your oral health a boost by receiving a vaccine on top of your regular dental care routine?
Researchers from the Wuhan Institute of Virology (WIOV) of the Chinese Academy of Sciences are working on such a vaccine, and their study has just been published in Scientific Reports.
Led by WIOV scientist Yan Huimin, the researchers tested a fusion of proteins to prevent the development of dental caries. Better known as dental cavities, caries is caused by the bacteria Streptococcus mutans (S. mutans).

An epidemiological survey has found there were about 400 million patients needing new teeth in China, but the number of qualified dentists was lagging behind demand.
In March this year the US Food and Drug Administration approved the use of a robot system named Yomi designed to assist human surgeons when fitting implants.
Successful procedure raises hopes technology could avoid problems caused by human error and help overcome shortage of qualified dentists.
