Orange glow and plants below: Wildfire smoke’s impact on crops

HumanNature

Smoke-driven changes in radiation have real world consequences beyond making for good film fodder and beautiful sunsets. For one, plants rely on solar radiation to grow, and the U.S. agricultural regions lie in the path of wildfire smoke, we need to understand how radiation changes impact different types of crops.

A deep dive into the IPCC’s updated carbon budget numbers

Real Climate

C warming estimate between 1850-1900 and 2006-2015. Let’s dive into each piece of this puzzle to understand what has changed between SR1.5 Warming to date – SR1.5 used a 0.97°C AR6 uses deep mitigation pathways assessed by SR1.5

Frequency and distance of human travel follows universal pattern, mobile-phone data reveals

Physics World

Gravity and radiation. The radiation model adds the component of other places people could stop on their journeys: the less places there are to stop – to go shopping or to work, for example – the further people will travel. The data were collected during different periods between 2006 and 2013.

New method predicts ‘stealth’ solar storms before they wreak geomagnetic havoc on Earth

Frontiers

This could help put measures in place that limit damage to technology and energy grids on Earth from the electromagnetic radiation. Unusually for stealth CMEs, their origin on the Sun was approximately known only because NASA’s twin STEREO spacecraft, launched in 2006, had happened to capture them ‘off-limb’.

The legacy of Liverpool’s forgotten synchrocyclotron

Physics World

Construction time The synchrocyclotron’s single magnet being slowly moved into place partially underground to help with radiation shielding. Being partially buried would help with radiation shielding, as well as the 30 tonne door, and walls comprised of nearly 1.8 m of concrete, behind which was approximately 3.7 m thick ceiling.

Celebrating a century of nuclear isomers

Physics World

But with our pulsed beam at Argonne, we could investigate what happens between pulses, making it easier to pick out the gamma rays emitted by an isomer of interest from the mess of radiation created by other reactions. In fact, our study showed that it takes 3.5?MeV The half-life of neutral thorium-229 atoms is 7??s
