‘These toxic pollutants are everywhere, and their usage is not banned’. For the first time, scientists at Northwestern Medicine have demonstrated a causal link between environmental phthalates (toxic chemicals found in everyday consumer products) and the increased growth of uterine fibroids, the most common tumors among women.

Manufacturers use environmental phthalates in numerous industrial and consumer products, and they’ve also been detected in medical supplies and food. Although they are known to be toxic, they are currently unbanned in the U.S.

“These toxic pollutants are everywhere, including food packaging, hair and makeup products, and more, and their usage is not banned,” said corresponding study author Dr...

Responsive material changes its behavior based on earlier conditions
Inspired by living systems, researchers at Aalto University have developed a new material that changes its electrical behaviour based on previous experience, effectively giving it a basic form of adaptive memory. Such adaptive materials could play a vital role in the next generation of medical and environmental sensors, as well as in soft robots or active surfaces.

Responsive materials have become common in a range of applications, from glasses that darken in sunlight to drug delivery systems...

A team of astronomers have found that planet formation in our young Solar System started much earlier than previously thought, with the building blocks of planets growing at the same time as their parent star.

A study of some of the oldest stars in the Universe suggests that the building blocks of planets like Jupiter and Saturn begin to form while a young star is growing. It had been thought that planets only form once a star has reached its final size, but new results, published in the journal Nature Astronomy, suggests that stars and planets ‘grow up’ together.

The research, led by the University of Cambridge, changes our understanding of how planetary systems, including our own Solar System, formed, potentially solving a major puzzle in astronomy.

“We have a pretty good i...

A new study at the Netherlands Institute for Neuroscience has examined how the dopamine system processes aversive unpleasant events.

It is well known that the dopamine system plays a crucial role in motivation, learning and movement. One of the main functions of dopamine is to predict the occurrence of rewarding experiences and the availability of rewards in our environment. In this context, the dopamine system informs our brains about so-called ‘reward prediction errors’ — the difference between received and predicted rewards. Dopamine neurons become more active when a reward occurs unexpectedly or if it is bigger than expected, and they show depressed activity when we receive less reward than predicted...
