The seemingly unlikely link could be driven by nature's ability to promote calm and enhance mental well-being—both cornerstones of a healthy pregnancy. (Read the research here1.)

As for the results, substituting seaweed into 10% of the average human's diet could save up to 110 million hectares (271 million acres; about the size of California and Texas combined) of land from being developed and prevent 2.6 billion tonnes of carbon from entering the atmosphere each year.

New research published in the journal Environmental Health found that those who had higher adherence to the Mediterranean diet (which is high in fruits, vegetables, whole grains, beans, legumes, nuts, seeds, omega-3-rich fish, poultry, eggs, cheese, yogurt, olive oil, herbs, and spices) had lower dietary CO₂ emissions. Following this eating pattern was also associated with lower land use, water consumption, and energy consumption. And like so many sustainable actions, this one is great for your personal health, too. (Read the research here.)

How's this for disturbing: A study published in Acta Ethologica found that birds who are exposed to urban noises develop different color beaks from those who are not. Researchers are unsure why this happens, but they suspect it could have to do with the way that human sounds increase corticosterone (a primary stress hormone in birds, akin to our cortisol), which impacts beak appearance. By driving these aesthetic changes, urban noise might also influence the way birds interact and choose mates. (Read the research here4.)

A first-of-its-kind study found that phthalates' adverse effects on metabolic health were passed down from male mice to two generations of offspring. "We found paternal exposure to endocrine-disrupting phthalates may have intergenerational and transgenerational adverse effects on the metabolic health of their offspring," lead researcher Changcheng Zhou, Ph.D., said in a statement. "To the best of our knowledge, our study is the first to demonstrate this." The next step is to test whether something similar is happening in humans. (Read the research here6.)

Those in the Northern Hemisphere can strive to get outside for at least two hours a week (the threshold that researchers have identified for boosting well-being7) through the frosty days of February. There's no need to go full Wim Hof here: Bundle up in plenty of layers to explore the landscapes around you through afternoon walks, winter sports, or mindful moments in the snow. We'll catch you in the spring.
