Gold Coast Mayor Tom Tate dismisses violation findings, says 'hard for me to apologize'

Gold Coast Mayor Tom Tate has dismissed two findings of misconduct by the council supervisor and said any apologies from him were insincere. Key points: Mayor appealed after court found he was involved in misconduct Tom Tate directed the board’s former chief executive to stop disciplinary proceedings against other staff members in 2015 Tate questions the order to make a confession of infringement on his Facebook page In a report published last week, the Councilor Conduct Tribunal found Tate to be involved in misconduct in 2015 when he directed former board chief executive Dale Dickson to stop disciplinary proceedings against other staff members. The report found that “the violations were taken so seriously that the court considered whether to recommend to the minister that [Mr Tate] dismissed as mayor. The court ordered Tate to make a public confession of the wrongdoing on his official Facebook page today and pay a fine of nearly $3,500. But Tate has appealed the findings and applied

Rapid bursts of radio waves from millions to billions of light-years away can be used as probes to study the halos of hazy gases that are hard to see.

Rapid bursts of radio waves from millions to billions of light-years away can be used as probes to study the halos of the hard-to-see hazy gas that surrounds closer galaxies. These pulses, known as fast radio bursts (FRBs), slow down as they transit through the gas shrouding the galaxy between their source and Earth. This has the added consequence of their radio frequency scattering. Using this to investigate the galaxy’s gaseous halo, researchers from the California Institute of Technology (Caltech) found twice as much matter as previously believed in the envelope surrounding the galaxy. This has implications for how this collection of stars and planets evolves over long periods of time. Astronomers looked at a sample of 474 distant FRBs with the Canadian Hydrogen Intensity Mapping Experiment (CHIME) which confirmed that the 24 FRBs intercepted by the galactic halo did indeed slow down compared to the others that traveled to Earth unimpeded. Thus, this effect can be used to investi

Chemists discovered the opposite effect: How dilution with water makes solutions hard

Credit: Koen Pieterse In Science TU/e researchers have published their study of new phase transitions of solutions and gels in water, which seem to contradict the basic principles of chemistry, and which they discovered by accident. In chemistry, hydrogels turn into liquids by diluting them with water. For the reverse transition, you increase the hydrogel concentration. However, TU/e ​​researchers led by Bert Meijer accidentally discovered that their liquid solution turned into a hydrogel when diluted. This phenomenon has never been studied or described before and can have consequences in many fields in chemistry and biology. This study focuses on the formation of certain hydrogels. This means that it starts with an aqueous solution of, in this case, two substances (a surfactant and a monomer). Research shows that gels form at a certain ratio of these two substances in water. This gel
