The machinery of mitosis: Kinetechores, centrioles and chromosome pumps
Researchers successfully clone adult human stem cells
Using analog computation circuits, engineers design cells that can compute logarithms, divide and take square roots
MIT engineers have transformed bacterial cells into living calculators that can compute logarithms, divide, and take square roots, using three or fewer genetic parts. Inspired by how analog electronic circuits ...
Sperm cells are extremely efficient at swimming against a current
Like salmon traveling upstream to spawn, sperm cells are extremely efficient at swimming against the current, according to research to be published this week.
Cellular computers: 'Genetic circuit' biological transistor enables computing within living cells
When Charles Babbage prototyped the first computing machine in the 19th century, he imagined using mechanical gears and latches to control information. ENIAC, the first modern computer developed in the 1940s, used vacuum ...
Knowing what to keep and what to trash: How an enzyme distinguishes cellular messages
Every once in a while, we are forced to sort that stack of papers on the kitchen counter. Interspersed between the expired coupons and dozens of takeout menus are important documents like your car insurance ...
Functional nerve cells from skin cells
A new method of generating mature nerve cells from skin cells could greatly enhance understanding of neurodegenerative diseases, and could accelerate the development of new drugs and stem cell-based regenerative ...
Microbiologists identify two molecules that kill lymphoma cells in mice
Researchers at the University of Southern California have identified two molecules that may be more effective cancer killers than are currently available on the market.
Bioengineers invent 'light tube array,' 'bioscilloscope' to test, debug genetic circuits
(Phys.org) —In a significant advance for the growing field of synthetic biology, Rice University bioengineers have created a toolkit of genes and hardware that uses colored lights and engineered bacteria ...
Actin cytonauts at play in the cell
First functional 'designer' chromosome synthesized in yeast
An international team of scientists led by Jef Boeke, PhD, director of NYU Langone Medical Center's Institute for Systems Genetics, has synthesized the first functional chromosome in yeast, an important step ...
Researchers use cryo-electron microscopy to learn how DNA wraps tightly around nucleosomes
'Lonely' bacteria increase risk of antibiotic resistance
Scientists from The University of Manchester have discovered that 'lonely' microbes are more likely to mutate, resulting in higher rates of antibiotic resistance.
Ancient enzymes function like nanopistons to unwind RNA
Molecular biologists at The University of Texas at Austin have solved one of the mysteries of how double-stranded RNA is remodeled inside cells in both their normal and disease states. The discovery may have implications ...
