Is beetlejuice stronger than teflon?

A protein-based lubricating substance is discovered in the femoro-tibial joint of the darkling beetle Zophobas morio (Insecta). The substance extrudes to the contacting areas within the joint and appears in a form of filiform flows and short cylindrical fragments. The extruded lubricating substance effectively reduces the coefficient of sliding friction to the value of 0.13 in the tribosystem glass/lubricant/glass. This value is significa… See More.

The evolutionary history of humans has just become more complicated, thanks to a new analysis in China and an excavation in Israel. Either we have just discovered new species of our ancestors or we have unearthed fossils of a known species of which we have had little physical evidence so far.


Chinese researchers will have much to contribute as palaeoanthropologists study the ‘Dragon Man’, who may have predated Neanderthals.

Reasonable minds may differ on the question of whether hydrogen fuel cells have a place in the clean-energy future. However, it’s a fact that the fossil fuel giants have been heavily hyping hydrogen, and it’s not hard to see why, as the vast majority of hydrogen is currently produced from natural gas.


Oil companies are working hard to appear “green,” but their true efforts are quite clear. Some will do whatever it takes to slow the pace of electrification.

Despite its biocidal properties, the use of hydrogen peroxide is still limited in the context of water disinfection. Here an approach is disclosed based on the generation of H2O2 in situ by means of an AuPd catalyst, which can compete with chlorination methods by generating a highly reactive radical flux.
