Resistance in tokamak vessel walls can cause disruptive energy loss
Under certain conditions, the fusion devices known as tokamaks can suffer a sudden loss of energy to the vessel walls. Researchers call this energy loss process a disruption. One cause is a magnetohydrodynamic (i.e., conducting plasma in a magnetic f.....»»

It"s not a match: Skill mismatch after job loss can have great impact on career
The loss of your job can be as devastating emotionally as a divorce. It's true that a divorce can actually enhance your marriage skills for the next time around, since the skills needed remain virtually unchanged, but the same cannot be said for job-.....»»
Nature degradation could cause a 12% loss to UK GDP, new analysis suggests
The deterioration of the UK's natural environment could lead to an estimated 12% loss to GDP, according to new analysis. In comparison, the financial crisis of 2008 took around 5% off the value of the UK GDP, while the COVID-19 pandemic cost the UK u.....»»
First-of-its-kind study shows that conservation actions are effective at halting and reversing biodiversity loss
A study published April 25, in the journal Science provides the strongest evidence to date that not only is nature conservation successful, but that scaling conservation interventions up would be transformational for halting and reversing biodiversit.....»»
Solar geoengineering to cool the planet: Is it worth the risks?
When I first wrote about geoengineering in 2012 , it was considered far-fetched at best, and crazy by most. But 12 years later, while there is still controversy and considerable resistance to deploying it, respectable scientists and institutions are.....»»
Scholars explain the ideology that says technology is the answer to every problem

Warming Arctic reduces dust levels in parts of the planet, study finds
Climate change is a global phenomenon, but its impacts are felt at a very local level. Take, for example, dust. Dust can have a huge impact on local air quality, food security, energy supply and public health. Yet, little is known about how global cl.....»»
Mobileye quarterly loss widens, revenue plunges as chip orders decline
