Nano-Probes Allow an Inside Look at Cell Nuclei

...lp repair DNA after irradiation. They have already visualized the dots' journey from the area surrounding the nucleus to inside the nucleus, a feat that opens the door for real-time observations of nuclear trafficking mechanisms. They also hope to target other cellular organelles besides the nucleus, such as mi...

Tadpole soon to help in the fight against cancer and lymphedema

...ssels. With the help of coloration techniques they visualized the areas in tadpoles where Prox1 is made: the lymphatic vessels. With the same coloration techniques the researchers indicated that the development of lymphatic vessels in tadpoles is comparable to mice and humans. A second part of their research wa...

Research Permits First-Ever Visualization of Psychological Stress in the Human Brain

...vania School of Medicine have, for the first time, visualized the effects of everyday psychological stress in a healthy human brain. Their work, performed at Penn's Center for Functional Neuroimaging, provides a neuro-imaging marker of psychological stress -- which will pave the way for the development of impr...

Molecular research suggest shift needed in how some drugs are created

...ata from the experiments allow the structure to be visualized down to angstrom-level resolution (one hundred-millionth of a centimeter). The structure of IRAK-4 was determined to a resolution of 1.7 angstroms. The molecules in question are part of innate immune systems -- an inherent immune response coded by D...

USC researchers track down the stem cells that create feathers

...he stem cells that produce bird feathers have been visualized and analyzed for the first time, signifying the initial step in a scientific journey that may ultimately shed light on human organ regeneration. The research, published in the December 15 issue of the journal Nature, was performed by a group of prom...

'Virus chip' detects new virus in prostate tumors

Biologists visualize protein interaction that may initiate viral infection

...ned together. It is the first time scientists have visualized the virus and CRD binding. "We formed the virus-CRD complex, took a snapshot and determined its structure," said Michael Rossmann, the Hanley Distinguished Professor of Biological Sciences in Purdue's College of Science. "Ultimately, researchers mig...

Sandia work launched on space shuttle shows live cells influence growth of nanostructures

...cess known as molecular self-assembly. This can be visualized as a kind of tract housing. In the current experiments, however, the construction process is altered by the live yeast or bacteria. During drying, the cells actively organize lipids into a sort of multi-layered cell membrane that not only serves ...

Pleasure and pain: Study shows brain's 'pleasure chemical' is involved in response to pain too

...ndividual variation in the rating of pain, and has visualized the brain's own painkiller system responding to pain and even to the giving of a "placebo" painkiller medication. Now, the team is working to examine the hormonal and genetic factors that may be different between people whose dopamine systems res...

NYU biologists identify gene that coordinates two cellular processes

... and expressing this fusion in early embryos, they visualized the movement of MEL-28 during cell division in living embryos. Consistent with the idea that MEL-28 had function in chromosome segregation and the nuclear envelope, the MEL-28-GFP fusion was observed to shuttle between the nuclear periphery and the c...

Living view in animals shows how cells decide to make proteins

Scientists at Duke University Medical Center have visualized in a living animal how cells use a critical biological process to dice and splice genetic material to create unique and varied proteins. The scientists say the findings, made in mice, help explain a key wonder of human biology: how the same genes fo...

A first glimpse of the influenza replication machine

...ange." Together with scientists at the IBS they visualized the atomic structure of the protein and discovered a previously overlooked signal that labels it for transport to the human nucleus where the genetic material of the virus is replicated. Cell microscopy studies at EMBL Heidelberg revealed that the hu...
