A recent study explored whether working memory training can reduce anxiety associated with a particular stressor — exam time. While working memory training did not appear to reduce test anxiety among students, perceived success during the training tasks did. The findings were published in the Journal of Cognitive Enhancement.
People who suffer from anxiety show deficits in working memory function. Working memory is a brain system that allows us to hold on to certain information and use it to guide our decisions and behavior. Scholars have found evidence to suggest that interventions that improve working memory also improve anxiety symptoms.
Little is known about how motivation might affect the success of working memory training on anxiety reduction. The authors of the new study elected to explore this topic among a sample of college students experiencing a particularly stressful season of the academic year — exam time.
Michael D. West talking about regeneration.

In this video, Dr. Michael West, CEO of AgeX Therapeutics, discusses the non-peer reviewed preprint article in bioRxiv on the potential role of the clustered protocadherin genes in regeneration, aging, and cancer, and the relevance of the discovery for iTR product development.

The ‘engine’ is actually a nanotube, powered by an enzyme-triggered biocatalytic reaction using urea as fuel. The reaction creates an internal flow that extends out into the fluid, causing an open cavity to form. This results in thrust, propelling the nanotube along.
Samuel Sánchez was one of the lead researchers from the previous record holders where their nanotube jet engine measured 600nm across and weighed 1 femtogram (10^−15 kg).
Xing Ma and Samuel Sánchez recognise both Ana C. Hortelao (Spain) and Albert Miguel-López (Spain) contribution to the research as well as the support from their affiliated institutions:

The Plasma Science and Fusion Center (PSFC) seeks to provide research and educational opportunities for expanding the scientific understanding of the physics of plasmas, and to use that knowledge to develop both fusion power and non-fusion applications.

Titanium is the leading material for artificial knee and hip joints because it’s strong, wear-resistant and nontoxic, but an unexpected discovery by Rice University physicists shows that the gold standard for artificial joints can be improved with the addition of some actual gold.
“It is about 3–4 times harder than most steels,” said Emilia Morosan, the lead scientist on a new study in Science Advances that describes the properties of a 3-to-1 mixture of titanium and gold with a specific atomic structure that imparts hardness. “It’s four times harder than pure titanium, which is what’s currently being used in most dental implants and replacement joints.”

Danny Key in his Wheel Horse Garden Tractor lined up against Freddie Ringlet (I think) in his Roper Garden Tractor, for what may be the first ever heads up tractor race!! Danny’s tractor is fitted with a Honda cbr1000 engine, out of a 1990’s bike. It has straight through pipes, and bell mouths on the carbs. The timing has also been advanced to enable it to run on VP race fuel. Danny said ‘it is a little down on compression, and he is just waiting on it going bang, before he can start on a rebuild’. The other tractor, I have no info on as yet. (any info appreciated)
Danny won both races with an 12.53 @ 107mph v 14.8 @ 90mph. and an 11.92 @ 108mph v 14.34 @ 92mph.
