Brain Pathway That Helps to Explain Light’s Effect on Mood Discovered

Summary: Neuroimaging study reveals how light-sensitive signals reach the brain and how regions associated with mood process those signals. Some regions of the cerebral cortex associated with cognitive and mood processing show sensitivity to light intensity.

From changes in daylight across seasons to the artificial lighting choices in workplaces, it’s clear that the quantity and quality of light that a person encounters can significantly impact mood.

Flood exposure and poverty in 188 countries

In an illuminating study, Rentschler et al. leverage data to analyze populations at risk of flood exposure. They explore the overlap between poverty, geography, and flood risk while taking into account pluvial, fluvial, and coastal flooding. Their work reveals that hundreds of millions of people in low-income regions are directly exposed to flood risk. The authors emphasize that efforts towards global flood mitigation should take socioeconomic factors into account since many low-income regions have both high flood risk and poor existing flood mitigation measures in place.

Floods are most devastating for those who can least afford to be hit. Globally, 1.8 billion people face high flood risks; 89% of them live in developing countries; 170 million of them live in extreme poverty making them most vulnerable.

State of the art for Europe’s demonstration fusion power plant

The European research consortium EUROfusion has announced the start of a five-year conceptual design phase for its demonstration fusion power plant DEMO, capable of net electricity production, shortly after the middle of the century in its Roadmap to Fusion Energy.

The first-of-its-kind facility represents the next technological step after the global ITER fusion experiment. It aims to demonstrate the net production of 300 to 500 megawatt of electricity generated by nuclear fusion, clean and safe energy, as well as essential technologies such as remote maintenance and tritium breeding. The tritium breeding technology will allow operators to produce the tritium fusion fuel on-site is a crucial requirement not just for DEMO but also for any future fusion power device to follow ITER.

Fusion is the process that powers stars like our Sun and promises an inherently safe and nearly unlimited long-term clean energy source here on Earth. Fusion energy will generate immense amounts of energy from just a few grams of the abundant fuels found all over the world.
