1. 4D bioengineering materials bend, curve like natural tissue
   Researchers have developed new 4D hydrogels -- 3D materials that have the ability to change shape over time in response to stimuli -- that can morph multiple times in a preprogrammed or on-demand manner in response to external trigger signals.

   
2. Deep dive into bioarchaeological data reveals Mediterranean migration trends over 8,000 years
   A team of international researchers has analyzed reams of data from the Neolithic to Late Roman period looking at migration patterns across the Mediterranean and found that despite evidence of cultural connections, there's little evidence of massive migration across the region.

   
3. COVID-19 lockdown highlights ozone chemistry in China
   Recently, the ozone season in China has been getting longer, spreading from summer into early spring and late winter. The COVID-19 lockdown can help explain why. Researchers found that decreases in NOx emissions are driving increased ozone pollution in late winter in China.

   
4. Velcro-like cellular proteins key to tissue strength
   Where do bodily tissues get their strength? New research provides important new clues to this long-standing mystery, identifying how specialized proteins called cadherins join forces to make cells stick -- and stay stuck -- together. The findings could lead to more life-like artificial tissues and tumor busting drugs.

   
5. Goodbye UTIs: Scientists develop vaccine strategy for urinary tract infections
   Researchers describe a new vaccination strategy that they think could re-program the body to fight off the bacteria that cause urinary tract infections.
