Magnet Lab researchers make observing cell functions easier
Now that the genome (DNA) of humans and many other organisms have been sequenced, biologists are turning their attention to discovering how the many thousands of structural and control genes -- the "worker bees" of living cells that can turn genes on and off -- function. view more (2008-05-09)
The closest look ever at native human tissue
Seeing proteins in their natural environment and interactions inside cells has been a long-standing goal. Using an advanced microscopy technique called cryo-electron tomography, researchers from the European Molecular Biology Laboratory [EMBL] have visualised proteins responsible for cell-cell contacts for the first time. view more (2007-12-06)
Tension in the nanoworld
A joint team of researchers at CIC nanoGUNE (San Sebastian, Spain) and the Max Planck Institutes of Biochemistry and Plasma Physics (Munich, Germany) report the non-invasive and nanoscale resolved infrared mapping of strain fields in semiconductors. view more (2009-01-26)
NEW APPROACH TO STICKY PROBLEM
"Over the past 20 years people have been trying to develop techniques for studying structures of polymer surfaces to understand how these determine their adhesive performance," says Dr Leggett of the Manchester research team. "However, such surfaces are extremely difficult to study directly. They degrade very quickly under beams of... view more... (1999-11-04)
Shedding new light on biology
Physicists at the European Molecular Biology Laboratory (EMBL) have developed a state-of-the-art microscope that gives scientists a much deeper look into living organisms than ever before. The new technology will undoubtedly become a standard fixture in modern biology labs. Its many advantages and applications are described in the latest edition... view more... (2004-08-09)
Nanoscale microscope sheds first light on gene repair
Proteins called H2AX act as "first aid" to DNA, among other roles. For the first time, scientists using the world's most powerful light microscope (the only one of its kind in the Americas) have seen how H2AX is distributed in the cell nucleus: in clusters, directing the first aid/repair after DNA injuries to the region where it is... view more...

Measuring Calcium in Serpentine Soils
Serpentine soils contain highly variable amounts of calcium, making them marginal lands for farming. Successful management of serpentine soils requires accurate measurement of the calcium they hold. Research published this month in the Soil Science Society of America Journal shows that multiple measurement techniques are needed to accurately... view more... (2008-08-20)
Plant Tomogram
New methods have emerged lately that allow to examine images of a living tissue without cutting it off an animal or a plant. The most advanced of them is the optical coherent tomography (OCT) method. The OCT device has been built and tried on plants by scientists from Nizhni Novgorod. Living tissues are turbid. They are almost impervious to the... view more... (2004-03-02)

Microscopic brain imaging in the palm of your hand
Researchers at Stanford University have demonstrated a promising, minimally invasive optical technique that can capture micron-scale images from deep in the brains of live subjects. view more (2005-08-25)
From biological imaging to Sudoku solutions
Cornell physicist Veit Elser has been engrossed recently in resolving a pivotal question in biological imaging. So he hasn't had much time for brainteasers and number games. view more (2006-03-06)
ETH Researchers Visualize the Binding of Proteins to the Nuclear Surface
Not only the genetic information of individual cells, but also that of the entire organism is stored within the cell nucleus. Each cell of a multicellular organism, e.g. man, contains the identical DNA sequences. The communication between the cell nucleus and the remainder of the cell is thus decisive for the correct functioning of the cells and... view more... (2003-01-15)
Fluorescent proteins illuminating biomedical research
Remarkable new tools that spotlight individual cellular molecules are transforming biomedical research. Scientists at the Gruss Lipper Biophotonics Center at the Albert Einstein College of Medicine of Yeshiva University have spearheaded their use in a series of papers, including one published today in the online version of Nature Methods. view more (2009-01-26)
New imaging method lets scientists 'see' cell molecules more clearly
Scientists have always wanted to take a closer look at biological systems and materials. From the magnifying glass to the electron microscope, they have developed ever-increasingly sophisticated imaging devices. view more (2009-01-21)
Rapid movements of living biomolecules visualised
Dutch researcher Chris Molenaar has made the rapid movements of proteins, DNA and RNA molecules visible in living cells. With this technique researchers can study the dynamics of biomolecules in their natural environment. Molenaar developed a method which makes it possible to follow the movements of RNA molecules in living cells. The researcher... view more... (2003-06-24)
Popular apple variety harbors unusual cell growth
A UK scientist has discovered clumps of previously-unreported callus hairs growing in the flesh of mature apples of Fuji and closely-related varieties, which may have storage implications for commercial growers. view more (2008-03-26)
Peering inside the skull of a mouse to solve meningitis mystery
NYU Langone Medical Center scientists and their collaborators at the Scripps Research Institute in La Jolla, Calif., have discovered an unexpected cause for the fatal seizures seen in mice with viral meningitis, an infection of the central nervous system, according to a study published in the journal Nature. view more (2008-12-23)
