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.
Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells arrange themselves into a variety of tissues and organs, such as the gut, muscles, and sensory systems. While not all animals have each of these tissues, they do all have one tissue, the germline, that produces sperm or eggs to propagate the species.
Our latest study, published in Applied Biochemistry and Biotechnology, explores a promising combinational therapy using mesenchymal stem cells (MSCs) and metformin to not only halt but potentially reverse lung fibrosis.
A couple of shocks awaited us before the taxi came. First, I looked up the flight status. Because it was not yet midnight, it gave me Monday's flight, whose status was "CANCELLED". (We knew about this because we had heard that the plane had to turn back with a fault, but it took me a…
Our team developed a stepwise self-assembly strategy using F127/TiO2 micelle hydrogels to create mesoporous TiO2 materials with precise control over architecture, pore size, and crystal structure. This method enables diverse nanostructures for applications in batteries and photocatalysts.
Every day, our bodies perform around 330 billion cell divisions to keep us alive and functioning. These divisions rely on the cell cycle, which has been in place since the earliest bacteria. The principle is the same: double the cell's content, then split into two "daughter" cells.
Chimeric antigen receptor T (CART) cell therapy has yielded impressive overall response rates in certain malignancies, but durable remissions remain low. T cell exhaustion alone does not account for all the therapy failures. Senescence can in part explain failures with 4-1BB costimulated CART cells.
