With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.

A handful of new studies moves the needle toward a consensus on the long-disputed question of whether insect wings evolved from legs or from the body wall, but the devil is in the details.

When I was a high school student, I came across Erwin Schrödingers What Is Life?. I still remember my exultant reaction—a combination of adolescent pride in feeling able to understand ideas considered beyond a young person’s means, and a genuine intellectual thrill engendered by the problems that Schrödinger addressed. Upon rereading the book, it appears to me that its major value was to provoke interest in a central problem of biology. Schrödinger’s question

Research into the biological basis of gender identity is in its infancy, but clues are beginning to emerge.

From detecting gravity and the Earth’s magnetic field to feeling heat and the movement of water around them, animals can do more than just see, smell, touch, taste, and hear.

Of Disciplines Author: Ricki Lewis Sometimes in science, the best way to move forward is to take a long look backward. For discoveries and data to be put into context and used as springboards for future inquiry, investigators must periodically synthesize and reflect on what has been accomplished, and determine what remains to be learned. A review article is one way to chart the evolution of a scientific discipline. Science has a rich review literature. Of 3,383 journals surveyed in the 1994 Sc

Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.

Biology happens on many levels, from ecosystems to electron transport chains. These tools may help spur discoveries at all of life's scales.

Marc Kirschner likes to expose biology's essential processes, such as how a simple microtubule can form such a variety of structures. Lucky for biology.

The COVID-19 pandemic is still with us. Biomedical innovation has rallied to address that pressing concern while continuing to tackle broader research challenges.
