Brain tissue kept alive for weeks on an artificial membrane

Researchers at the RIKEN Center for Biosystems Dynamics Research in Japan have developed a new system for keeping tissue viable for long-term study once transferred from an animal to a culture medium. The new system uses ...

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
