Scientists develop silk microneedles to deliver nutrients and chemicals to plants

When farmers apply pesticides to their crops, 30 to 50% of the chemicals end up in the air or soil instead of on the plants. Now, a team of researchers from MIT and Singapore has developed a much more precise way to deliver ...

Detecting nanoplastics in body fluids: New method combines optofluidic force and Raman spectroscopy

Microplastics and much smaller nanoplastics enter the human body in various ways, for example through food or the air we breathe. A large proportion is excreted, but a certain amount remains in organs, blood, and other body ...

Scientists find evidence of universal conformal invariance in diverse cellular movement

In a new Nature Âé¶¹ÒùÔºics study, researchers have provided evidence of universal conformal invariance in living biological cells. They show that a universal feature in the collective behavior emerges in groups of living cells.
