- With Record Resolution And Sensitivity, Tool Images How Life Organizes In A Cell Membrane
10-02-2006 · ScienceDaily
What's the difference between a lifeless sack of chemicals and a living cell? It's all in the way they're organized, according to Stanford biophysical chemist Steven Boxer. With colleagues at Stanford, the University of California-Davis and Lawrence Livermore National Laboratory, he has developed a way to image cell membranes with unprecedented resolution-on the order of 100 nanometers, a scale larger than individual molecules but much smaller than entire cells.

- Team of scientists develops non-invasive method to track nerve-cell development in live human brain
11-08-2007 · EurekAlert!
A team of scientists including researchers at Cold Spring Harbor Laboratory have identified and validated the first biomarker that permits neural stem and progenitor cells to be tracked, non-invasively, in the brains of living human subjects. This important advance could lead to significantly better diagnosis and monitoring of brain tumors and a range of serious neurological and psychiatric disorders.

- Getting to the bottom of memory
01-05-2007 · EurekAlert!
Researchers from the European Molecular Biology Laboratory's (EMBL) Mouse Biology Unit in Monterotondo, Italy, and the Universidad Pablo de Olavide in Sevilla, Spain, now for the first time investigate the molecular basis of memory in living mice. The study, which appears in the current issue of Learning and Memory, identified a molecule that is crucially involved in learning and singled out the signaling pathway through which it affects memory.

- SBUMC Researchers First to Image a Biomarker of Neurogenesis
11-09-2007 · Brookhaven National Laboratory
Mirjana Maletic-Savatic, M.D., Ph.D, and co-investigators from Stony Brook University Medical Center, Brookhaven National Laboratory and Cold Spring Harbor Laboratory have discovered a way to image a biomarker of neural stem and progenitor cells (NPCs) in the living human brain. This discovery allows researchers to monitor neurogenesis, the development of nerve tissues.

- Soft-cell approach cuts animal tests
02-06-2007 · EurekAlert!
A new way to test the safety of the air we breathe is proving faster, cheaper and more humane than exposing laboratory animals to airborne chemical hazards, say UNSW scientists. Researchers at the university's Chemical Safety and Applied Toxicology Laboratories have developed an animal-free alternative that exposes living human cells to air pollutants inside a small chamber. The breakthrough could fast-track scientific understanding of the threat to human health posed by thousands of airborne chemical compounds.

- Scientists uncover how hormones achieve their effects
10-22-2007 · EurekAlert!
New insights into the cellular signal chain through which pheromones stimulate mating in yeast have been gained by scientists at the European Molecular Biology Laboratory. Similar signal chains are found in humans, where they are involved in many important processes such as the differentiation of nerve cells and the development of cancer. A sophisticated microscopy technique allowed the researchers to observe for the first time the interplay of signalling molecules in living yeast cells.

- MIT creates 3-D scaffold for growing stem cells
12-26-2006 · EurekAlert!
Stem cells grew, multiplied and differentiated into brain cells on a new three-dimensional scaffold of tiny protein fragments designed to be more like a living body than any other cell culture system.

- Dig deeper to find Martian life
01-30-2007 · EurekAlert!
Probes designed to find life on Mars do not drill deep enough to find the living cells that scientists believe may exist well below the surface of Mars, according to research led by UCL (University College London). Although current drills may find essential tell-tale signs that life once existed on Mars, cellular life could not survive the radiation levels for long enough any closer to the surface of Mars than a few metres deep -- beyond the reach of even state-of-the-art drills.

- Nanotech promises big things for poor -- but will promises be kept?
02-27-2007 · EurekAlert!
"Nanotechnology has the potential to generate enormous health benefits for the more than five billion people living in the developing world," according to Dr. Peter A. Singer, senior scientist at the McLaughlin-Rotman Centre for Global Health and Professor of Medicine at University of Toronto. "Nanotechnology might provide less-industrialized countries with powerful new tools for diagnosing and treating disease, and might increase the availability of clean water."
