What Makes Life Tick? Mitochondria May Keep Time for Cells
Every species develops at its own unique tempo, leaving scientists to wonder what governs their timing. A suite of new findings suggests that cells use basic metabolic processes as clocks.
What Causes Alzheimer’s? Scientists Are Rethinking the Answer.
After decades in the shadow of the reigning model for Alzheimer’s disease, alternative explanations are finally getting the attention they deserve.
Protein Blobs Linked to Alzheimer’s Affect Aging in All Cells
Protein buildups like those seen around neurons in Alzheimer’s, Parkinson’s and other brain diseases occur in all aging cells, a new study suggests. Learning their significance may reveal new strategies for treating age-related diseases.
Powerful ‘Machine Scientists’ Distill the Laws of Physics From Raw Data
Researchers say we’re on the cusp of “GoPro physics,” where a camera can point at an event and an algorithm can identify the underlying physics equation.
Ancient Genes for Symbiosis Hint at Mitochondria’s Origins
Was the addition of mitochondria a first step in the formation of complex cells or one of the last? A new study of bacteria tries to answer this contentious question in evolutionary biology.
Cells Blaze Their Own Trails to Navigate Through the Body
With self-generated gradients of chemicals and physical tension, cells in the body steer themselves to vital destinations.
Most Complete Simulation of a Cell Probes Life’s Hidden Rules
A 3D digital model of a “minimal cell” leads scientists closer to understanding the barest requirements for life.
