Molecular bait can help hydrogels heal wounds

Like fishermen, Rice University bioengineers are angling for their daily catch. But their bait, biomolecules in a hydrogel scaffold, lures microscopic stem cells instead of fish.

Plant stem cells require low oxygen levels

Plants function as the green lungs of our planet, and rightfully so, as the capacity of a large, single tree releases more than 120 kg of oxygen into the Earth's atmosphere every year through a series of sunlight-fuelled ...

Microbeads allow ultrasonic waves to stimulate cells more safely

Researchers at Duke University have discovered a way to enhance the effectiveness and safety of sonogenetics or ultrasonic modulation, emerging techniques that use sound waves to control the behavior of individual neurons ...

Modified peptides could boost plant growth and development

A new Australian study of peptide hormones critical for plant development could result in wide-ranging benefits for agriculture, tissue culture, and related industries, and even improve knowledge of peptides in humans.
