Every living thing on Earth stems from same 20 amino acids, and now scientists...

Earth didn't always harbor life. But around 4 billion years ago, something in the environment changed, and systems with biological properties began to emerge. Many scientists...

Scientists discover new chemistry that may help explain the origins of life

Before life began on Earth, the environment likely contained a massive number of chemicals that reacted with each other more or less randomly. It is...

Why only humans are prone to heart attacks

In a new study, researchers found out why only humans are prone to heart attacks. They say the loss of a single gene two to...

DNA helicopters offer insight into how biological machines power living things

For decades, researchers have chased ways to study how biological machines power living things. Every mechanical movement — from contracting a muscle to replicating DNA...

Scientists prove insects also feel chronic pain for the first time

Scientists have known insects experience something like pain since 2003, but new study proves for the first time that insects also experience chronic pain...
Metabolomes A new way to store data in little space

Metabolomes: A new way to store data in little space

New research shows it’s possible to store image files in solutions of common biological small molecules. The work is toward molecular storage systems that could...

DNA test helps solve 25-year-old shark bite mystery

When Jeff Weakley tweezed open a blister-like bulge on his foot, he was not expecting to find a piece of tooth from a shark...

Why humans are so much fatter than chimps, despite sharing 99% of same DNA

The answer may have to do with an ancient shift in how DNA is packaged inside fat cells. Blame junk food or a lack of...
New gene editor could fix major shortcoming of current CRISPR tech

New gene editor could fix major shortcoming of current CRISPR tech

Scientists at Columbia have developed a gene-editing tool—using jumping genes—that inserts any DNA sequence into the genome without cutting, fixing a major shortcoming of...
Scientists recreate cell division outside a cell for the first time

Scientists recreate cell division outside a cell for the first time

Every living thing moves—prey from predators, ants to crumbs, leaves toward sunlight. But at the most fundamental level, scientists are still struggling to grasp the...
