The current practice of freezing embryos—used to assist reproduction in humans or animals or to conserve endangered species—routinely causes ice to form within the cells, ripping through cell membranes, changing the way proteins ...
A tiny sea creature might hold the secret to reversing the aging process. When treated with a brief series of electrical pulses, sea squirts experience dramatic and long-lasting health improvements that can significantly ...
Researchers in Spain have discovered that in collectives of moving fire ants, rippling "waves" of density and activity are likely triggered by local regions where ants collectively travel in the same direction as their neighbors.
Living cells cool much slower than our current understanding of heat conduction can explain, according to new research from the University of Tokyo. Researchers have used two techniques—high-speed temperature mapping and ...
A core challenge in biology is understanding how processes in the body, such as cellular development and regeneration, unfold over long stretches of time, making them notoriously difficult to view at the molecular level. ...
NASA had a big—and little—problem. For a small satellite, the agency needed a tiny antenna, with very specific communication capabilities and very strict limits on size and weight. The agency gave the problem to a design ...
The outer regions of the brain, the cortex, have specific layers of different cells—neurons—that are similarly ordered among all mammals, from tiny mouse brains to huge elephant brains. However, the proportions of different ...
Stem cells are the original cell type from which all other cells and tissues in the body develop through a very tightly regulated process. However, how stem cells differentiate in addition to gene-control systems, such as ...
Researchers at Hannover Medical School (MHH) have developed a method for the efficient production of human immune cells, such as macrophages, in medium-sized bioreactors. These immune cells can be derived from induced pluripotent ...
For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic manipulation. The models ...
