Bronze Age humans racked up travel miles

A new study indicates long journeys and unexpected genetic links in Bronze Age Eurasian cultures.

Genetics

DNA tags mostly deleted in human germ cells

Human embryos come with some heavy-duty erasers. Chemical tags on DNA get mostly wiped out in the womb.

Genetics

Extinct species may get a second chance

An evolutionary biologist explains the obstacles scientists must overcome to revive extinct species.

Genetics

White House hits pause on editing human germline cells

The White House has hit pause, for now, on clinical experiments that could alter the human germ line.

Genetics

Genes and environment balance each other

Genes and environment have equal influence on human traits.

Genetics

A billion years of evolution doesn’t change some genes

Human genes can substitute for 47 percent of essential genes in baker’s yeast, new research shows.

Genetics

Mutations that drive cancer lurk in healthy skin

Healthy tissue carries mutations that drive cancer, samples of normal skin cells show.

Genetics

Ancient DNA pushes back timing of the origin of dogs

DNA extracted from the fossil of an ancient wolf indicates dogs and wolves diverged longer ago than previously thought.

Genetics

How to rewire the eye

The cutting-edge technology called optogenetics may offer a workaround to partially restore vision even after the retina’s light-sensing rods and cones die.

Genetics

Quicker sepsis diagnosis may be a step closer

Identifying genes linked with sepsis may make it possible to develop a blood test to diagnose the infection days sooner than current methods.

Genetics

MicroRNAs track radiation doses

MicroRNAs in the blood may indicate radiation damage, a study of mice finds.

Genetics

Molecular scissors snip at cancer’s Achilles’ heel

Finding cancer’s vulnerable spots using CRISPR technology could lead to drugs that hit the disease hard.
