World could breach 1.5C warming threshold in 7 years: Study
The world may cross the crucial 1.5C global warming threshold in seven years as fossil fuel CO2 emissions continue to rise, scientists warned Tuesday, urging countries at the COP28 talks to "act now" on coal, oil and gas pollution......»»
New understanding of "oobleck-like" fluids contributes to smart material design
If you mix cornstarch and water in the right proportions, you get something that seems not-quite-liquid but also not-quite-solid. Oobleck flows and settles like a liquid when untouched but stiffens when you try to pick it up or stir it with a spoon......»»
When physics meets biology: Prion protein orchestrates liquid–liquid phase separation with copper
In a study published in Science Advances, researchers from the Federal University of Rio de Janeiro (UFRJ) and the German Center for Neurodegenerative Diseases (DZNE-Berlin) shed light on the intricate dance between the prion protein and copper ions.....»»
Low emissions and economic survival—countries in the global south aren"t getting a fair deal
In 2015, more than 140 countries signed up to the goal of achieving net-zero emissions by 2050. For countries in the global south this is a huge task. On the one hand, they have committed to low emissions. On the other their economic survival depends.....»»
Researchers develop a new approach to polarization-independent LC phase modulation
Liquid-crystal (LC) phase modulators are widely used in optical systems because of their advantages of low power consumption, lightweight, flexible bandwidth adjustment, and non-mechanical movements. However, most LC phase modulators are polarization.....»»
