Aligned peptide 'noodles' could enable lab-grown biological tissues

Quantifying U.S. health impacts from gas stoves

A new study of air pollution in U.S. homes reveals how much gas and propane stoves increase people's exposure to nitrogen dioxide, a pollutant linked to childhood asthma. Even in bedrooms far from kitchens, concentrations frequently exceed health limits while stoves are on and for hours after burners and ovens are turned off.

Physics confirms that the enemy of your enemy is, indeed, your friend

The famous axiom 'the enemy of my enemy is my friend' is part of Austrian psychologist Fritz Heider's social balance theory, introduced in the 1940s. Previous studies have tried to model social networks based in famous theory but results remained controversial. New model takes into account two key pieces simultaneously: Not everyone knows everyone else in a social network, and some people are friendlier than others. With those two constraints, large-scale social networks consistently align with social balance theory. Model has broad applications for exploring political polarization, neural networks, drug interactions and more.
