Scottish company IceRobotics has taken a further step towards bringing its innovative robotic milking technology to market thanks to a second round investment package of £430,000. This includes £75,000 from NESTA (the National Endowment for Science, Technology & the Arts), the organisation that invests in UK creativity and innovation.
IceRobotics has developed a sophisticated vision-based sensor that can precisely target and track a cow’s teats, capturing the 3D coordinate data required to then attach robotic milking equipment. The system uses stereo vision in the same way as the human eye, replacing laser technologies used at present. Alongside this the company is developing a technology that uses a dextrous mechanical actuator that bends like an elephant’s trunk, so that fragile or delicate objects like a cow’s teat can be easily manoeuvred without causing injury. Together these technologies will be key components of the latest generation of milking equipment that will improve hygiene for livestock and increase milk yield for farmers.
Research has long shown that cows produce more milk if they are milked more frequently. More recent studies have found cow’s preferred milking time to be between 11pm and 2am, just before the cow settles down to sleep and a common milking time for a calf. The time when most dairy farms do their morning milking – between 3am and 6am – instead coincides with the cow’s natural “deep sleep” time. This is because dairy farm routines have been dictated by regimes that suit the farmer rather than the cow. In contrast, robotic milking systems allow the cow voluntarily access whenever she wants, and without the farmer needing to be present. As well as resulting in happier cows, this can increase milk yields by as much as 20% due to the cow being milked three or even four times a day.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
