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.
Results provide the first measurements of how sea-ice algae and other single-celled life adjust to the dramatic seasonal rhythms in the Southern Ocean. The results provide clues to what might happen as this ecosystem shifts under climate change.
Javier Ramón Azcón, an ICREA research professor and the leader of the Biosensors for Bioengineering group at the Institute for Bioengineering of Catalonia (IBEC), has been granted an "ERC Proof of Concept Grant."
Foraminifera are tiny, single-celled organisms that live in the oceans. Their hard shells, made of calcium carbonate, can withstand the test of time and their fossils reveal a lot about Earth's history, ...
A new study sheds new light on the origins of modern brain cells. Researchers find evidence that specialized secretory cells found in placozoans, tiny sea creatures the size of a grain of sand, have many similarities to the neuron, such as the genes required to create a partial synapse. From an evolutionary point of view, early neurons might have started as something like these cells, eventually gaining the ability to create a complete synapse, form axons and dendrites and create ion channels that generate fast electrical signals -- innovations which gave rise to the neuron in more complex animals such as jellyfish. Though the complete story of how the first neuron appeared remains to be told, the study demonstrates that the basic building blocks for our brain cells were forming in the ancestors of placozoans grazing inconspicuously in the shallow seas of Earth around 800 million years ago.
