As commercial spaceflight draws ever closer and time spent in space continues to extend, the question of reproductive health ...

In a recent study, researchers manipulated cellular proteins that control genes in aged mice. Experimental results showed their livers were rejuvenated to younger states. This work shows promise as a ...

Humans' exposure to high temperature burn injuries may have played an important role in our evolutionary development, shaping ...

Muscles make up nearly 40% of the human body and power every move we make, from a child's first steps to recovery after injury. For some, however, muscle development goes awry, leading to weakness, ...

Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...

Fear has a scent. Here’s how this invisible chemical signal has shaped human perceptions, emotions and survival instincts.

Assembloids: A Versatile Platform for Human Tissue Modeling. This schematic illustrates the classification of assembloids based on four key assembly strategies—multi-region, multi-lineage, ...

The new evolutionary study found two main reasons for the primate anomaly: to attract mates and to threaten rivals.

Harvard Faculty of Arts and Sciences has officially voted to change the name of the Human Evolutionary Biology concentration during a meeting on April 1. Effective as of July 1, 2025 — when the ...

The most complex engineering of human cell lines ever has been achieved by scientists, revealing that our genomes are more resilient to significant structural changes than was previously thought. The ...
