What Does It Look Like to “Turn On” a Gene?
In the murky darkness, blue and green blobs are dancing. Sometimes they keep decorous distances from each other, but other times they go cheek to

RNA sequencing may help doctors diagnose hepatocellular carcinoma earlier, according to preliminary data presented Sunday (March 31) at the American Association for Cancer Research annual
Researchers have come up with a new method to control brain cells in live animals using specially designed receptor proteins that respond to the drug
Doctors have confirmed that two four-year-old children in Brisbane, Australia, are “semi-identical” twins, making them just the second case of this type of twin ever
HeLa cells have now been cultured for nearly 70 years in many labs across the world, and were long considered to be an infinite supply
The Japanese government’s health ministry has given the go-ahead for a trial of human induced pluripotent stem cells to treat spinal cord injury, Reuters reports
An international team of researchers has successfully reprogrammed human α cells into insulin-producing β cells, according to a study published yesterday (February 13) in Nature.
DNA methylation status in a variety of tissues can accurately reveal the age of an animal, but previously discovered epigenetic clocks often aren’t evolutionarily conserved.
In 2007, Ho Man “Holly” Tang took a break from her undergraduate biology studies at Iowa State University to join her older brother, Ho Lam
Traces of the bacterium Porphyromonas gingivalis, which causes chronic gum disease, have been found in the brains of people who had Alzheimer’s disease. The result
Researchers have long puzzled over why many eukaryotic protein-coding genes are interspersed with segments of noncoding DNA that have no obvious biological function. These so-called
Scientists have for the first time grown functioning human blood vessel organoids from stem cells in the lab. Their study, published on Wednesday (January 16)
We live in a medicated era. Recent data indicate that more than half of Americans are currently taking prescription drugs. Among pregnant women this number
Two studies in mice published today (October 31) in Nature report the existence of several types of brain cells that had not been acknowledged before.
Mice that model a severe form of Alzheimer’s disease tend to exhibit improved memory after exercise-induced neuron production, according to a report in Science today
Researchers have used three types of stem cells to create a mouse embryo in a dish, according to research published in Nature Cell Biology yesterday
CAR-T therapies—genetically engineered T cells that destroy cancer cells—have proven to be promising options when other treatments fail. However, there’s currently no one-size-fits-all CAR T,
Researchers used magnetically driven microrobots to carry cells to predetermined spots within living zebrafish and mice, they report in Science Robotics today (June 27). The
In 1898, Camillo Golgi, an eminent Italian physician and pathologist, published a landmark paper on the structure of “nervous cells.” In addition to the organelle
With their pluripotency and ability to self-renew, some cancer cells have been likened to stem cells. Now, researchers show that the similarities between the cells
Last May, to much fanfare, an international group of researchers published two papers describing a new in vitro system that had maintained human embryos in
On a fall day in 2015 at Sunnybrook hospital in Toronto, a dozen people huddled in a small room peering at a computer screen. They
Base editing is a relatively recent genome-editing technique that swaps one DNA base pair for another, offering researchers the potential to correct harmful, single-nucleotide mutations
One day in 2006, while a postdoc in the Rockefeller University laboratory of Nathaniel Heintz, I had an unexpected eye-opener. Heintz showed me some electron
NA comes in many shapes and sizes. Over the past few decades, researchers have characterized at least two dozen different RNA varieties beyond the textbook
