Daily rhythms in mRNA polymerase II transcription and histone modifications influence gene expression programs responsible for the temporal gating of liver physiology and metabolism in mammals.
A collaboration between Lehigh University physicists and University of Miami biologists addresses an important fundamental question in basic cell biology: How do living cells figure out when and where to grow?
A mathematician from the University of Bristol has teamed up with a biologist from the University of Edinburgh to address a major problem in molecular biology.
Scientists using high-powered microscopes have made a stunning observation of the architecture within a cell – and identified for the first time how the architecture changes during the formation of gametes, also known as sex cells, in order to successfully complete the process.
MIT researcher Andreas Mershin has a vision that within a few years, people in remote villages in the developing world may be able to make their own solar panels, at low cost, using otherwise worthless agricultural waste as their raw material.
This new and tactile view of a cell undergoing division comes thanks to a specialized protein called MiniSOG. This illustration shows the molecule zipping toward the reader, fluorescent and standing out crisply from an electron microscope image.
Swiss researchers provide evidence that a protein in the cell nucleus responds to environmental stimuli like a kind of sensor, regulates genes accordingly and thus exchanges information with the cell memory.
A protein machine unwinds DNA molecules... This crescent-shaped protein complex (yellow in the image) wraps around and bends DNA (the red and blue complex) to help unwind it.
Together Harvard University and XVIVO developed this 3D animation journey for Harvard's undergraduate Molecular and Cellular Biology students about the microscopic world of mitochondria.
Cellular automata are probably the closest things to machine life that most people have gotten an opportunity to experiment with in recent years. John Conway invented a piece of software titled the Game of Life in 1970. He carefully set up the rules to create a balanced world. While this might sound like old news, it has allowed scientists to actually simulate certain real world systems.
Living Architecture: How Synthetic Biology Can Remake Our Cities (TED) by Rachel Armstrong. iPad, Kindle, Barnes & Noble. Rooted in cutting edge biology and materials science, as well as contemporary art, Armstrong's account of how we'd build biological cities feels at first like a thought experiment but evolves into a plausible vision of tomorrow's cities.
A montage of fluorescent microscopy images depicts pluripotent mouse stem cells that have been encouraged to develop into various kinds of specialized tissues by a mix of chemical signals.
(PhysOrg.com) -- Cornell researchers have peered into the complex molecular network of receptors that give one-celled organisms like bacteria the ability to sense their environment and respond to chemical changes as small as 1 part in 1,000.
