How does misinformation and the cost of sunscreen impact sun protection behaviors, particularly among young Canadians?

The rise in melanoma is linked to inadequate sunscreen use, fueled by misinformation on social media, cost concerns, and the misconception that darker skin doesn't need protection. A study showed that nearly 60% of young Canadians spend extended time in the sun without sunscreen, resulting in higher sunburn rates. This highlights the need for targeted education and addressing socioeconomic barriers to access.

How are European countries responding to the potential influx of US researchers?

Trump's funding cuts, impacting approximately $1 trillion in US research spending (3.5% of US GDP), with 40% dedicated to technological advancements, have created a brain drain opportunity for other nations. Many researchers, especially those pursuing doctoral or postdoctoral studies (three out of four, according to Nature), are considering leaving the US due to these policies. This trend reverses the historical flow of talent towards the US, driven by its historically generous research funding.
