In this sequence, a spinach leaf is stripped of its plant cells, a process called decellularization, using a detergent. The process leaves behind the leaf's vasculature. Researchers at Worcester Polytechnic Institute (WPI) were able to culture beating human heart cells on such decelluralized leaves. Credit Worcester Polytechnic Institute

Heart Tissue Grown On Spinach Leaves

Researchers face a fundamental challenge as they seek to scale up human tissue regeneration from small lab samples to full-size tissues, bones, even whole organs to implant in people to treat disease or traumatic injuries:…

At ambient temperature, the circadian clock of cyanobacteria is constantly ticking and its 'molecular cogwheels' keep spinning. This makes it difficult to understand the clockwork mechanism. Cooling down the clock puts its cogwheels to rest, allowing to visualize details of their appearance and assembly. Credit Philip Lossl, Utrecht University

Operation Of Ancient Biological Clock Uncovered

Ten years ago, researchers discovered that the biological clock in cyanobacteria consists of only three protein components: KaiA, KaiB and KaiC. These are the building blocks — the gears, springs and balances — of an…
