How Webb's coronagraphs reveal exoplanets in the infrared

Phys.org 

NASA's James Webb Space Telescope has many different observing modes to study planets orbiting other stars, known as exoplanets. One way in particular is that Webb can directly detect some of these planets. Directly detecting planets around other stars is no easy feat. Even the nearest stars are still so far away that their planets appear to be separated by a fraction of the width of a human hair held at arm's length. At these tiny angular scales, the planet's faint light is lost in the glare of its host star when trying to observe it.

Biochar and energy from pyrolysis can pave the way for carbon-neutral agriculture in China

Phys.org 

Agriculture accounts for a large share of global greenhouse gas emissions, and the path to carbon neutrality is not straightforward. Researchers from Land-CRAFT—Center for Landscape Research in Sustainable Agricultural Futures at Aarhus University and others have, through a comprehensive life cycle analysis of data from China, identified an integrated biomass pyrolysis and electricity generation system coupled with commonly applied methane and nitrogen mitigation measures that, together with the right management of agricultural land...

Firefighters gain on early Spain wildfire

France24.com (en) 

The blaze has ravaged 3,800 hectares (9,500 acres) of mainly forest since Thursday and is the first to be recorded so early in a season, which officials say now runs from spring to autumn, rather than just the summer. The fire broke out near the eastern village of Villanueva de Viver, where unseasonably warm temperatures neared 30 degrees Celsius (86 degrees Fahrenheit) on Friday and has already forced the evacuation of nearly 1,700 people. Prime Minister Pedro Sanchez said the blaze proved "the climate emergency exists". Читать дальше...

Regional UN Forum Urges Countries To Rescue Sustainable Development Goals Amid Compounding Crises

Eurasia Review 

Never before have development gains in Asia and the Pacific been at such risk of being swept away by overlapping and intensifying crises. The Tenth Asia-Pacific Forum on Sustainable Development (APFSD) opened Monday in Bangkok with a resounding call for countries to make radical changes at the midpoint of the 2030 Agenda or risk evaporating their slim chances of achieving the Sustainable Development Goals (SDGs).

'Glassiness' and 'blurriness' might explain the behavior of high-entropy superconductors

Phys.org 

Researchers from Tokyo Metropolitan University have uncovered clues to understanding the behavior of high-entropy metal telluride superconductors. They found that features typical of glasses, solids with an amorphous structure, and "blurry" electronic states, induced by disorder in the atomic structure, were involved in the unique pressure dependence of the critical temperature where superconductivity arises. This might point to coupling between electrons and vibrations in the atomic lattice, giving rise to exotic superconductivity mechanisms. Читать дальше...

A robust phase extraction method for overcoming spectrum overlapping in shearography

Phys.org 

In the same way as the traditional optical interference technique, shearography obtains object deformation information by obtaining the phase, and the measured object is often dynamic in practical applications, so the spatial carrier method, which can extract the phase information from a single speckle pattern, becomes a necessary phase extraction method for the practicalization of shearography. However, due to the coupling relationship between shearing amount and spatial carrier frequency, the spatial... Читать дальше...
