Forever chemicals in household objects linked to type 2 diabetes, scientists warn PFAS can disrupt metabolism and increase diabetes risk, study finds

PFAS, the forever chemicals, are a risk factor for several chronic diseases, such as obesity, liver disease, and diabetes as well as cancers, reproductive harm, and immune system suppression. Shouldn't they be banned and replaced by safe alternatives asap?

A gut sense for a microbial pattern regulates feeding - Nature A study reveals a gut–brain sensory pathway through which the microbial component flagellin activates neuropod cells in the colon to signal the brain and reduce feeding in mice.

🧪
PPY-positive gut neuropod cells detect bacterial flagellin through TLR5 signaling to vagal neurons, thereby controlling feeding.

Graphic with text explaining Earth Overshoot Day 2025. It reads: “Today is Earth Overshoot Day 2025. We’ve already used up all the natural resources Earth can regenerate this year. It’s like spending your entire annual salary by July and borrowing from your kids’ future income. The more we overspend, the less there’ll be to grow from.” At the bottom are the name “Silvia Pineda-Munoz, PhD” and the Climate Ages logo. The background shows a field of green crops under a partly cloudy blue sky.

This is figure 2. The plot shows the distribution of work hours at baseline (in red) and at endpoint (in green). Panel a presents company-level average work hours. Panel b presents individual-level work hours.

A study in Nature Human Behaviour finds that four-day work weeks without a reduction in income boost workers’ job satisfaction and physical and mental health, driven by enhanced work performance, lower levels of fatigue and fewer sleep problems. go.nature.com/3Um75MP #econsky 🧪

Climate change is bad for agriculture and food security.

This study found that even considering adaptation and development, crop yields are likely to decline by 2050 and 2100 (vs. baseline projected yield growth with no climate change) in every region of the world. 🧪

A Shiba Inu dog, light brown with a white belly, is lying on a patterned rug. The dog has its tongue out, looking relaxed and content. It is holding a green and purple plush toy in its paws.

A study in Scientific Reports suggests that the way dogs engage with TV may depend on their personalities. Excitable dogs were more likely to follow on-screen objects while fearful or anxious dogs were more likely to respond to stimuli such as cars or a doorbell. go.nature.com/4eQKDVy 🧪
