Microscopy with helium ions may greatly enhance both surface and sub-cellular imaging

The ability to obtain an accurate three-dimensional image of an intact cell is critical for unraveling the mysteries of cellular structure and function. However, for many years, tiny structures buried deep inside cells have been practically invisible to scientists due to a lack of microscopic techniques that achieve adequate resolution at the cell surface and through the entire depth of the cell.

Three papers reveal structure and workings of G protein-coupled receptors

Three international teams of scientists, led by researchers at the University of California San Diego, University of Michigan and Stanford University, have published a trio of papers describing in unprecedented detail the structure and workings of G protein-coupled receptors (GPCRs), a large family of human proteins that are the target of one-third to one-half of modern drugs.

IBN scientists harness ultrasmall peptides to repair spinal disc damage

New ultrasmall peptides that can be used as building blocks for a wide range of regenerative applications such as spinal disc replacement and cartilage repair have been developed by scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute. These peptides spontaneously assemble in water to form hydrogels, which resemble collagen, a major component of connective tissues found in cartilage, ligaments, tendons, bone and skin.

Study reveals structure of ribosomal assembly intermediate

As part of a joint research effort with the University of Michigan, scientists from the Florida campus of The Scripps Research Institute have for the first time defined the structure of one of the cell's most basic engines, which is required for cell growth, as it assembles from its components.

Flatworms provide new insight into organ regeneration, evolution of mammalian kidneys

Our bodies are perfectly capable of renewing billions of cells every day but fail miserably when it comes to replacing damaged organs such as kidneys. Using the flatworm Schmidtea mediterranea-famous for its capacity to regrow complete animals from minuscule flecks of tissue-as an eloquent example, researchers at the Stowers Institute for Medical Research demonstrated how our distant evolutionary cousins regenerate their excretory systems from scratch.

New cold electron source could improve quality and speed of nanoimaging for drug development

A new source of very cold electrons will improve the quality and speed of nanoimaging for drug and materials development to a trillionth of a second.

Scientists define structure of astrovirus that causes juvenile diarrhea

Rice University scientists have defined the structure -- down to the atomic level -- of a virus that causes juvenile diarrhea. The research may help direct efforts to develop medications that block the virus before it becomes infectious.

Berkeley Lab scientists reveal how protein-making machine bends without breaking

It sounds like hype from a late-night infomercial: It can twist and bend without breaking! And wait, there's more: It could someday help you fend off disease!

Study suggests causal link between HSV1 and Alzheimer's disease

Laboratories at the University of New Mexico (UNM), Brown University, and House Ear Institute (HEI) have developed a new technique to observe herpes simplex virus type 1 (HSV1) infections growing inside cells. HSV1, the cause of the common cold sore, persists in a latent form inside nerve cells.

California Institute chemistry professor receives ACS award for 'ultrafast-motion' imaging

Ahmed H. Zewail, Ph.D., 1999 Chemistry Nobel Laureate and Linus Pauling Professor of Chemistry & Professor of Physics at the California Institute of Technology, today will receive the 2011 Priestley Medal, the highest honor bestowed by the American Chemical Society, the world's largest scientific society.

Research outlines how cilia disease gene products regulate early cilium formation

An international collaboration jointly led by University College Dublin, University of Alabama and Simon Fraser University, British Columbia has outlined in the Journal of Cell Biology how cilia disease gene products regulate important aspects of early cilium formation and the integrity of the ciliary transport gate.

Study finds synapses between retinal ganglion cells and starburst amacrine cells distributed asymmetrically

The sensory cells in the retina of the mammalian eye convert light stimuli into electrical signals and transmit them via downstream interneurons to the retinal ganglion cells which, in turn, forward them to the brain. The interneurons are connected to each other in such a way that the individual ganglion cells receive visual information from a circular area of the visual field known as the receptive field.

Scientist develops cryo-electron microscopy to clarify salmonellae structure

Bacteria like salmonellae infect their host cells by needle-shaped extensions which they create in large numbers during an attack. A group of Vienna-based scientists headed by Thomas Marlovits employed recently developed methods of cryo-electron microscopy and have been able to clarify the structure of this infection apparatus on the near-atomic scale.

Neuropathologist receives AAN Potamkin Prize for Alzheimer's disease research

The American Academy of Neurology has awarded the 2011 Potamkin Prize to Dennis Dickson, M.D., a neuropathologist at Mayo Clinic in Florida and the Robert E. Jacoby Professor for Alzheimer's Disease Research.

Connectome remains dynamic during development, says Scripps Research

Connected highways of nerve cells carry information to and from different areas of the brain and the rest of the nervous system. Scientists are trying to draw a complete atlas of these connections-sometimes referred to as the "connectome"-to gain a better understanding of how the brain functions in health and disease.
