Scientists Have Discovered a New Set of Blood Groups

The unborn baby was in trouble. Its mother’s doctors, at a UK hospital, knew there was something wrong with the fetus’s blood, so they decided to perform an emergency C-section many weeks before the baby was due. But despite this, and subsequent blood transfusions, the baby suffered a brain hemorrhage with devastating consequences. It sadly […]

There’s New Proof Crispr Can Edit Genes Inside Human Bodies

The Crispr components can’t naturally get into cells on their own, so Intellia uses a delivery system called lipid nanoparticles—essentially tiny fat bubbles—to ferry them to the liver. In Intellia’s trials, patients receive a one-time IV infusion of these Crispr-laden nanoparticles into the veins in their arms. Since blood passes through the liver, lipid nanoparticles […]

To Understand Brain Disorders, Consider the Astrocyte

This was slow going. “We spent a lot of time, probably the first couple of years, really just working out the immunopanning and culturing the astrocytes,” recalls Caldwell. One challenge was making sure that the media contained few proteins to start with—those would have interfered with their measurements. The scientists also needed to make sure […]

Epigenetic ‘Clocks’ Predict Animals’ True Biological Age

A new tool from Belsky and his colleagues, introduced in 2020 and updated earlier this year, acts as an aging speedometer. In creating their Pace of Aging biomarker, they quantified the rate of change in 19 markers of organ function at four ages, compiled them into a single index, and modeled it with methylation. “We’re […]

How a ‘Living Drug’ Could Treat Autoimmune Disease

In lupus, a type of autoimmune disease, the body’s natural defense system can’t tell the difference between its own cells and foreign ones, so it mistakenly attacks its own tissues and organs. The attackers are molecules called autoantibodies, which turn against the body instead of protecting it from invaders, like normal antibodies do. They trigger […]

A GMO Purple Tomato Is Coming to Grocery Aisles. Will the US Bite?

In December 2004, plant scientist Cathie Martin went to the greenhouse to check on her tomatoes. The tiny fruits, about the size of gumdrops, were still green. These miniature tomatoes, a variety widely used in research labs, normally become red upon ripening. But when Martin came back after Christmas, they were starting to turn purple—just […]
