New probe measures cell stiffness and traction
University of Illinois scientists have developed a tiny mechanical probe that can measure the inherent stiffness of cells and tissues, as well as the internal forces that cells generate and exert upon one another. It is the first probe able to quantify both properties, according to its developers. Read More
Artificial nerve cells closely mimic biological ones
Researchers at Sweden’s Linköping University have created an artificial neuron that closely mimics the characteristics of biological nerve cells. They describe the work in a study, published recently in Nature Materials, indicating that the artificial neuron can stimulate natural nerves, making it a promising technology for various medical treatments.

Lab grown mature neurons hold promise for neurodegenerative disease therapy
Northwestern University-led researchers have created the first highly mature neurons from human induced pluripotent stem cells. The study, published January 12 in the journal Cell Stem Cell, holds potential for new neurodegenerative disease therapies. Read More
Magnetic microdroplets reveal how cells sense mechanical signals during tissue development
Manipulation of magnetic microdroplets has revealed how stem cells in a living embryo mechanically test their environment to communicate with neighboring cells. Read More
MIT researchers record cellular memories through protein chains
Using engineered proteins, MIT researchers have designed a system in which they can record “memories” of sequences of cellular events, such as when certain genes are activated, or how cells respond to a drug, as cells turn on series of genes and pathways in performing functions. Read More
Boosting RNA therapies to create natural pacemakers
Smidt Heart Institute scientists have investigated how biological pacemaker cells fight back against RNA therapies to correct abnormal heartbeat rates. Read More
Discovery of toxin linked to severe COVID-19 points to new way to treat disease
A viral toxin produced by the SARS-CoV-2 virus may damage cell barriers, inducing vascular leak and driving severe COVID-19 infections, according to researchers at the University of California, Berkeley (UC Berkeley). Read More
AI provides evidence that gene length explains age-related molecular changes
Artificial intelligence (AI) has helped Northwestern University researchers find evidence that the length of genes explains most of the molecular-level changes that occur during aging, which they contend could lead to therapeutics that slow or even reverse the process. Read More
Functional genomics reveals gateway to intracellular targets for large molecules
Complementary genome-scale, chemical-genetic approaches have revealed a cellular gateway that could allow large molecules to enter cells, providing new opportunities to develop drugs for intracellular targets, according to University of California San Francisco (UCSF) researchers. Read More
Sound waves sort extracellular vesicles to enable liquid biopsies, regenerative therapies
Duke University engineers have used sound waves to separate small extracellular vesicles from biofluids, laying the groundwork for the development of next-generation liquid biopsies and regenerative therapies. Read More
