The Cell Phone: A History The cell phone is one of the most revolutionary inventions of the modern era. Since the first commercially available cell phone was released in 1983, the device has changed the way we communicate and stay connected. From the first brick-sized mobile phones to today's sleek, pocket-sized versions, the cell phone has gone through numerous iterations over the past three decades. In this article, we take a look back at the history of the cell phone and the various milestones that have defined its evolution.
Researchers from the German Primate Center—Leibniz Institute for Primate Research and the Max Planck Institute of Molecular Cell Biology and Genetics have discovered two specific genes that evolve exclusively in humans jointly influence the development of the cerebrum. They have thus provided evidence that these genes contribute together to the evolutionary enlargement of the brain.
A team of Singapore scientists has made a significant discovery in understanding stomach cancer, a disease that remains one of the deadliest cancers worldwide. By using advanced mapping technologies, they created a detailed "atlas" of stomach tumors, revealing hidden patterns in how cancer cells behave, evolve and interact with their environment. These insights could lead to more precise, targeted treatments that improve survival rates and reduce side effects.
In vertebrates, the skeleton of different regions of the body arises from different precursor cells. Researchers at the University of Basel have now discovered that these skeletal cells do not just differ in their developmental origin, but also in their gene regulation—which may be a key to the vertebrates' evolutionary success story.
A study presents a striking example of cooperative organization among cells as a potential force in the evolution of multicellular life. The study is based on the fluid dynamics of cooperative feeding by Stentor, a relatively giant unicellular organism.
Humans like to think that being multicellular (and bigger) is a definite advantage, even though 80% of life on Earth consists of single-celled organisms—some thriving in conditions lethal to any beast.
We’re heading to Atlanta for the 57th Annual NCSM Conference! This year’s theme, Rise Up with Bold Mathematics Leadership, resonates deeply with our commitment to equity, excellence, and innovation in math education. We’re looking forward to connecting with fellow educators and leaders as we explore powerful sessions on accelerating student learning, transformative practices, and coaching strategies that lift teacher practice and support every learner.
