Think of tissues as mosh pits of cells. The cells may not be able to crowd surf, but they can jam.
Specifically, cells can undergo a jamming transition, a physical role change that was previously known to occur only among foams, sand and other nonliving materials. It’s one of the ways that physicist Lisa Manning has shown how...
Assisted pregnancies give infertile couples the chance at a child. But kids conceived with reproductive technologies, such as in vitro fertilization, or IVF, were more likely to develop high blood pressure as adolescents than their naturally conceived counterparts, a new study finds.
Of 52 teens conceived with technological help, eight had hypertension, defined as blood pressure...
Salamanders and lizards can both regrow their tails, but not to equal perfection.
While a regenerated salamander tail closely mimics the original, bone and all, a lizard’s replacement is filled with cartilage and lacks nerve cells. That contrast is due to differences between stem cells in the animals’ spinal cords, researchers report online August 13 in Proceedings of the National...

Scientists now know how long it takes for a cell to tell itself it’s time to die.
Signals triggering a type of cell suicide called apoptosis move through a cell like a wave, traveling at a rate of 30 micrometers per minute, Stanford University systems biologists Xianrui Cheng and James Ferrell Jr. report in the Aug. 10 Science.
These findings resolve a debate over whether these...
Babies exposed to a Zika infection while in the womb are not out of the woods even if they look healthy at birth.
Nearly 1 in 10 of 1,450 babies examined developed neurological or developmental problems, such as seizures, hearing loss, impaired vision or difficulty crawling, a study from the U.S. Centers for Disease Control and Prevention finds. It’s the first tally of the health of...
A once-maligned genetic parasite may actually be essential for survival.
Mouse embryos need that genetic freeloader — a type of jumping gene, or transposon, called LINE-1 — to continue developing past the two-cell stage, researchers report in the July 7 Cell.
Many scientists “charge that these are nasty, selfish genetic elements” that jump around the genome, making mutations and...
