Scientists have finally resolved the structure of the molecule that responds to chili peppers, high temperatures and spider toxins.
Scientists have discovered building blocks similar to those in modern RNA that can effortlessly assemble when mixed in water and heated.
Some organisms respond to stress by driving up their mutation rate. Are they evolving specific mechanisms to enhance evolution in times of crisis?
Mysterious episodes of genetic duplication in our great ape ancestors may have paved the way for human evolution.
A rare brain stimulation study suggests that a brain circuit known as the “salience network” contributes to differences in our ability to overcome challenges and cope with stress.
Analyzing individual cancer cells could reveal the answer to some of the disease’s most enduring mysteries.
Neuroscientists have identified a network of highly linked brain regions that could prove essential in integrating information and facilitating higher-order cognitive tasks.
New technologies have launched the life sciences into the age of big data. Biologists must now make sense of their windfall.
Machine learning techniques are helping scientists pinpoint the mutations that allow bird and pig viruses to infect humans.
In the complex architecture that ferries fluids in plants and brains, scientists are finding a model of resilience.
Population expansion may be a major driver in the evolution of cooperation, with implications for new antibiotics, cancer treatments and perhaps even human behavior.
Symbiotic bacteria that dwell within insect cells are intricately intertwined with their hosts, prompting scientists to question when these bacteria stop being bona fide organisms and become part of the cell.
More genetic data is available than ever before to help build evolutionary trees, but scientists are finding that different genes even in the same organism can tell conflicting stories.
