NEW YORK (AP) — People with a DNA mutation that reduces their chance of HIV infection may die sooner, according to a study that suggests tinkering with a gene to try to fix one problem may cause others. The study authors cited the case of the Chinese researcher who tried to produce this mutation in...

Visitors to the Oklahoma City National Memorial walk around the "Survivor Tree," a 100-year-old American elm and symbol of hope after the deadly 1995 bombing, Friday, April 19, 2019, in Oklahoma City. Science and technology are helping Oklahoma City to sustain the DNA of the tree symbolizing hope 24 years after the deadliest act of domestic terrorism on U.S. soil. As part of an annual remembrance of the bombing, civic leaders on Friday plan to transplant a tree that was cloned from the scarred American elm that lived through the blast. They hope the younger elm will replace the "Survivor Tree" once it dies. (AP Photo/Adam Kealoha Causey)

NEW YORK (AP) — Just about every week, it seems, scientists publish the unique DNA code of some creature or plant. Just in February, they published the genome for the strawberry, the paper mulberry tree, the great white shark and the Antarctic blackfin icefish. They also announced that, thanks to a...

A scientist at the NY Genome Center in New York demonstrates equipment used in single-cell RNA analysis on Wednesday, Sept. 26, 2018. Until recently, trying to study key traits of cells from people and other animals often meant analyzing bulk samples of tissue, producing an average of results from many cell types. But scientists have developed techniques that let them directly study the DNA codes, and its chemical cousin RNA, the activity of genes and other traits of individual cells. (AP Photo/Malcolm Ritter)

NEW YORK (AP) — Did you hear what happened when Bill Gates walked into a bar? Everybody there immediately became millionaires — on average. That joke about a very rich man is an old one among statisticians. So why did Peter Smibert use it to explain a revolution in biology? Because it shows...
