Moving faster in a crowd

Cell particles move more quickly through a crowded cellular environment when the crowding molecules are non-uniformly distributed. New research also shows that particle transport in crowded cells can actually be faster than ...

Using CRISPR to program gels with new functions

The CRISPR genome-editing system is best-known for its potential to correct disease-causing mutations and add new genes into living cells. Now, a team from MIT and Harvard University has deployed CRISPR for a completely different ...

DIY pump takes science out of the lab

A simple pressure pump, made from balloons and nylon stockings, will give more people in more places the ability to test for water contaminants and analyze blood samples.

Raising fluid walls around living cells

Cell culture plates that are in everyday use in biology can be effectively transformed into microfluidic devices, opening paths for biologists to miniaturize cell-based workflows. In a recent report, Ph.D. researcher Cristian ...

3-D-printed device detects biomarkers of preterm birth

Preterm birth (PTB)—defined as birth before the 37th week of gestation—is the leading complication of pregnancy. If doctors had a simple, accurate and inexpensive way to identify women at risk for the condition, they ...

Biosensor 'bandage' collects and analyzes sweat

Like other biofluids, sweat contains a wealth of information about what's going on inside the body. However, collecting the fluid for analysis, usually by dripping or absorbing it from the skin's surface, can be time-consuming ...
