California is burning for very good reasons, like climate change and population growth. But it doesn’t have to be this way.

Research led by the University of Bristol has begun to unpick an important mechanism of antibiotic resistance and suggest approaches to block this resistance.
Antibiotic resistance is the ability of bacteria to defend against antibiotic attack, and the spread of these resistance mechanisms amongst bacteria is a global public health concern. A form of resistance caused by a family of bacterial proteins, the Verona Imipenemase (VIM) beta-lactamases, is of acute clinical concern because it can inactivate antibiotics (penicillins and related agents) that comprise over half of the global antibacterial market.
A team of researchers led by the University of Bristol have uncovered near-atomic level structural detail of VIM proteins. The research is published today [Thursday 15 November] in The FEBS Journal.

In collaboration with fellow researchers, chemists at the Technical University of Munich (TUM) have developed a process that, according to initial calculations, can facilitate economically removing the greenhouse gas carbon dioxide from the atmosphere. The latest World Climate Report (IPCC Special Report on Global Warming of 1.5 ° C) acknowledges the global relevance of the process.

Ancient continents were found under Antarctic ice, thanks to old data from a now-dead European satellite.
New analysis of data from the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) mission has revealed rocky zones called “cratons” in the Earth’s lithosphere, a zone between our planet’s crust and mantle. GOCE plunged into Earth’s atmosphere five years ago this month after the craft ran out of orbital-maneuvering fuel. While scientists were unable to predict exactly where GOCE would fall, no debris dropped into populated areas.

Tokamaks like EAST could help us do just that. They’re devices that use magnetic fields to control plasma in a way that could support stable nuclear fusion, and it’s this plasma that EAST heated to such an incredible temperature.
Going Nuclear
Not only is EAST’s new plasma temperature milestone remarkable because, wow, it’s really hot, it’s also the minimum temperature scientists believe is needed to produce a self-sustaining nuclear fusion reaction on Earth.

The day of clean, limitless energy from nuclear fusion has taken another step closer thanks to China’s Experimental Advanced Superconducting Tokamak (EAST). During a four-month experiment, the “Chinese artificial sun” reached a core plasma temperature of over 100 million degrees Celsius – that’s more than six times hotter than the interior of the Sun – and a heating power of 10 MW, enabling the study of various aspects of practical nuclear fusion in the process.

A new planet, more than three times the mass of Earth, has been discovered orbiting our closest single star. The discovery, which took more than 20 years to make, marks a change in the way we look for new planets.
This is the first time a planet of its size, known as a super-Earth, with an orbital period of 200 days, has been found using a well-established method; by measuring the fractional changes in the speed of the star caused by the planet orbiting around it.
