Two newly-developed driverless cars systems can identify a user's location and orientation in places where GPS does not function, and identify the various components of a road scene in real time on a regular camera or smartphone, performing the same job as sensors costing tens of thousands of dollars. 

Although the systems cannot currently control a driverless car, the ability to make a machine 'see' and accurately identify where it is and what it's looking at is a vital part of developing autonomous vehicles and robotics. 

If you are in science, the genome editing method called CRISPR  is not new, it has been all the rage since 2012 because of its superior ability of CRISPR to deliver a gene to the right spot compared to its genome editing competitors.

A pair of socks embedded with miniaturized microbial fuel cells and fueled with urine pumped by the wearer's footsteps has powered a wireless transmitter to send a signal to a PC., the first self-sufficient system powered by a wearable energy generator based on microbial fuel cell technology. 

A day or two ago, local ITV featured a news item about a man who had kept the same plastic bulk issue shopping carrier bag for 34 years, using it from time to time.

The bag celebrated 50 years since the first Tesco store was opened in 1929, and he had acquired this one in 1981, the year of the first London Marathon.


My new book came out on Amazon yesterday, and as I breath a long sigh of relief, I'm reflecting on how I reached that milestone and how technology made it both easier and more difficult to achieve. If you are a writer looking to self-publish an eBook on science or any other complex subject, you might want to consider what I've learned over the last few months.

If you think you really made a difference by overlaying your Facebook profile with a French flag, take 10 seconds to sign an online petitition or retweet a celebrity who matches your beliefs about science, you are a "slacktivist" - an activist who doesn't really care enough to do anything worthwhile.

Policymakers dismiss you smf friends don't take you seriously as you flit from cause célèbre to  cause célèbre, but you might be making a difference after all.

The examination room computer promises safer, more efficient and more effective patient care. But exam room computing is challenging and there is growing evidence that it can be a threat to patient safety and detrimental to good relationships and health outcomes, according to a commentary in JAMA Internal Medicine.

Regenstrief Institute sociologist Richard Frankel, Ph.D. presents POISED, a model he has devised for developing and reinforcing good exam room computer-use by physicians.

The dye business of the 19th century was a mature, fast-moving and international industry, according to an analysis of four purple dresses. The study found that a brand new purple dye went from first synthesis to commercial use in just a few years.

Before the 1800s, purple dye came at a premium, so it was usually restricted to royalty -- hence the connection between royals and purple. The 19th century saw the discovery of several synthetic purple dyes, making purple textiles more affordable and readily available. Understanding where these dyes came from and were used is therefore of historical interest.

Can you trust any Yelp review when some restaurants create fake online restaurants as portals to avoid their own bad reviews, or pay for good ones? 

And as organizations like the American Council on Science and Health quickly learned, when a cabal of anti-science groups, like SourceWatch, US Right To Know, Natural News, and Joe Mercola team up with Mother Jones to undermine your work, the public will rightfully only look skin deep and not realize the negative press is being manufactured.

Research efforts on the intestine have increased in recent years. Owing to its enormous surface area - comparable to that of a one-bedroom apartment - and the huge number of neurons it contains - comparable to that in the brain - the intestine is sometimes referred to as the abdominal brain. In addition to absorbing nutrients from the foods we eat, it influences our immune status and metabolism.

With the help of sensors, specialized cells in the intestinal wall determine which hormones, if any, should be released into the bloodstream. Overall, it acts as a highly sophisticated control center.
