In this article you will learn how to build a programmable Snap Circuits Rover by adding a PICAXE micro controller.

PubMed Central is costing biomedical journal sites readership and that effect is increasing over time.

The bulk of modern biomedical studies are controlled by the government, which means taxpayer-funding, so it makes sense that the results would be available to the public, but Phillip M. Davis writing in The FASEB Journal says that PubMed draws readership away from the scientific journal even when journals themselves are providing free access to the articles.

The current situation and future prospects for biosimilars is similar to that of small molecule drugs, according to an analysis by Research and Markets: they get to benefit from patent expiry. On this basis, prospects for biosimilars might look good, with the vast majority of leading originator brands in the global biologics market expected to lose some degree of protection by 2019. 

An international team of physicists has proposed a revolutionary laser system inspired by telecommunications technology that could be used in both fundamental research at laboratories such as CERN and more applied tasks such as proton therapy and nuclear transmutation. 

Researchers in the Sheffield Centre for Robotics have been working to program a group of 40 robots that 'swarm' together to carry out jobs. So far, they have demonstrated that the swarm can carry out simple fetching and carrying tasks, by grouping around an object and working together to push it across a surface.  

The robots can also group themselves together into a single cluster after being scattered across a room, and organize themselves by order of priority.  The programming for that part is simple. If the robots are being asked to group together, each robot only needs to be able to work out if there is another robot in front of it. If there is, it turns on the spot; if there isn't, it moves in a wider circle until it finds one. 

Modern DNA sequencing techniques have been turned toward creating a
highly sensitive, quantifiable analysis of animal, plant, and microbial substances present in foodstuffs.

In pilot studies, the researchers were able to use their new DNA method to detect the presence of a 1% content of horse meat in products and to determine the actual amount with a high level of precision.

The researchers even found slight traces of the DNA of added mustard, lupin, and soy in a test sausage prepared for calibration purposes, something that could also be of interest with regard to allergy testing of foods.
