Direct methane conversion under mild conditions by thermo-, electro- or photocatalysis reviewed

Direct conversion of Earth-abundant methane into value-added chemicals under mild conditions is an attractive technology in response to the increasing industrial demand for feedstocks and the worldwide appeal of energy conservation. Exploring advanced low-temperature C-H activation catalysts and reaction systems is the key to converting methane in a direct and mild manner.

Electrified methane reformer produces far less carbon dioxide

A team of researchers from several institutions in Denmark, along with colleagues from Sintex and Haldor Topsoe, has developed an electrified methane reformer that produces far less CO2 than conventional steam-methane reformers. In their paper published in the journal Science, the group describes their new technology and how well it works. Kevin Van Geem, Vladimir Galvita and Guy Marin with the Laboratory for Chemical Technology and Center for Sustainable Chemistry in Ghent have published a Perspective piece on the work done by the team in the same journal issue.

A newly discovered mechanism reveals how Parkinson's disease can spread between brain cells

Tiny channels between nerve cells are involved in a newly discovered mechanism of how Parkinson's disease can spread throughout the brain, according to new research from Linköping University, Sweden. The results demonstrate that harmful protein aggregates, or deposits, can bind and "hitch a lift" with channel-forming proteins, and in this way spread to healthy cells. The study has been published in Acta Neuropathologica.

Study corroborates the influence of planetary tidal forces on solar activity

One of the big questions in solar physics is why the sun's activity follows a regular cycle of 11 years. Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), an independent German research institute, now present new findings, indicating that the tidal forces of Venus, Earth and Jupiter influence the solar magnetic field, thus governing the solar cycle. The team of researchers present their findings in the journal Solar Physics.
