New imaging system with higher resolution

Applied Precision, Inc. a leading provider of imaging, measurement, and analysis systems for the life sciences industries announced that it will introduce a new imaging system at the American Society for Cell Biology (ASCB) annual conference with twice the resolution of traditional microscopes.

Mathematical models of adaptive immunity

More than five million people die every year from infectious diseases, despite the availability of numerous antibiotics and vaccines. The discovery of penicillin to treat bacterial infections, along with the development of vaccines for previously incurable virus diseases such as polio and smallpox, achieved great reductions in mortality during the mid-20th century.

Scans show immune cells intercepting parasites

Researchers may have identified one of the body's earliest responses to a group of parasites that causes illness in developing nations.

Aperio Technologies receives another patent for TDI arrays in microscope slide scanners

Aperio Technologies, Inc., (Aperio), a global leader in digital pathology for the healthcare and life sciences industry, announced today that the United States Patent and Trademark Office has issued the company patent No. 7,457,446 entitled "Fully Automatic Rapid Microscope Slide Scanner."

New imaging technique helps find brain cells key to learning

More than a century after Ivan Pavlov's dog was conditioned to salivate when it heard the sound of a tone prior to receiving food, scientists have found neurons that are critical to how people and animals learn from experience.

Biologists spy close-up view of poliovirus linked to host cell receptor

Researchers from Purdue and Stony Brook universities have determined the precise atomic-scale structure of the poliovirus attached to key receptor molecules in human host cells and also have taken a vital snapshot of processes leading to infection.

Scientists film immune cell becoming infected by a parasite

Forget what's number one at the box office this week. The most exciting new film features the intricate workings of the body, filmed by scientists using ground-breaking technology.

Natural killer T cells play important role in Lyme disease

A research team led by the La Jolla Institute for Allergy & Immunology and Albany Medical College has illuminated the important role of natural killer (NK) T cells in Lyme disease, demonstrating that the once little understood white blood cells are central to clearing the bacterial infection and reducing the intensity and duration of arthritis associated with Lyme disease.

Alpha-catenin protein provokes healthy cell bonding

In human relationships, a certain "spark" often governs whether we prefer one person more than another, and critical first impressions can occur within seconds. A team lead by Johns Hopkins researchers has found that cell-to-cell "friendships" operate in much the same way and that dysfunctional bonding is linked to the spread of cancer.

New technique provides closer look at DNA and mRNA

In a study in the advance online edition of Nature Structural and Molecular Biology, researchers from Albert Einstein College of Medicine describe a technique for looking more precisely at a fundamental step of a cell's life - a gene, DNA, being read into a message, mRNA.

Six bad bugs increasingly escaping effects of antibiotics

Infectious disease experts warn that new drugs are urgently needed to treat six drug-resistant bacteria that cause most hospital infections and increasingly escape the effects of antibiotics.

New cell analysis platform developed - commercial partners sought

Sandia National Laboratories is seeking commercial partners to license or contribute to the continued development of a new lab-on-a-chip platform for high-throughput manipulation and interrogation of individual cells, one that enables quantitative analysis of cellular behaviors with unprecedented speed, resolution, sensitivity, and multiplexing.

Multitasking proteins driving cell behavior

A study describing how cells within blood vessel walls move en masse overturns an assumption common in the age of genomics - that the proteins driving cell behavior are doing so much multitasking that it would be near impossible to group them according to a few discrete functions.

Potential gene target for treatment of common hearing, vertigo and balance problems

A UCLA study shows for the first time how microscopic crystals form sound and gravity sensors inside the inner ear.

How microscopy can unlock the key to disease

A leading international scientist will reveal how the latest techniques in microscopy - including time-lapse imaging of living cells - are leading to breakthroughs in understanding genetic and acquired diseases.

Tiny protein provokes healthy bonding between cells

In human relationships, a certain "spark" often governs whether we prefer one person to another, and critical first impressions can occur within seconds.

Scientists develop 'barcode chip' to revolutionize diagnostic medical testing

In less than 10 minutes, and using just a pinprick's worth of blood, the chip can measure the concentrations of dozens of proteins, including those that herald the presence of diseases like cancer and heart disease.

Scientists shed light on how DNA is unwound so that its code can be read

Researchers at The Scripps Research Institute have figured out how a macromolecular machine is able to unwind the long and twisted tangles of DNA within a cell's nucleus so that genetic information can be "read" and used to direct the synthesis of proteins, which have many specific functions in the body.

Scientists create new soap free emulsion polymerization process

Research chemists at the University of Warwick have devised an elegant process which simply and cheaply covers small particles of polymer with a layer of silica-based nanoparticles.

Scientists develop unlimited pure insulin-producing cells from mouse embryonic stem cells

These pure insulin-producing cells, which according to electron microscopy studies, have the same sub-cellular structures as the insulin-producing cells naturally found in the pancreas, were highly effective in treating diabetes in the mouse model.
