New software tools for fast, accurate reconstruction of neural networks

The human brain is the most complex of all organs, containing billions of neurons with their corresponding projections, all woven together in a highly complex, three-dimensional web. To date, mapping this vast network posed a practically insurmountable challenge to scientists.

Expert offers air quality control tips

A mold count of more than 50,000 has triggered an alert for dangerous air quality throughout the Midwest . The Midwest experienced a record-breaking winter for snow, and is again setting new records for heat and rain.

Invadopodia could help survival of cancer cells

Delicate, threadlike protrusions used by cancer cells when they invade other tissues in the body could also help them escape control mechanisms supposed to eliminate them, a research group led by led by Bradley Davidson in the University of Arizona's department of molecular and cellular biology reports in Nature Cell Biology.

Carcinogenesis is just another form of speciation, proposes new theory

Cancer patients may view their tumors as parasites taking over their bodies, but this is more than a metaphor for Peter Duesberg, a molecular and cell biology professor at the University of California, Berkeley.

Erionite in North Dakota roads may increase risk of mesothelioma

As school buses drive down the gravel roads in Dunn County, North Dakota, they stir up more than dirt. The clouds of dust left in their wake contain such high levels of the mineral erionite that those who breathe in the air every day are at an increased risk of developing mesothelioma, a type of cancer of the membranes around the lungs, new research shows.

Researchers identify elusive gene responsible for Grey Platelet Syndrome

Researchers have identified an elusive gene responsible for Grey Platelet Syndrome, an extremely rare blood disorder in which only about 50 known cases have been reported. As a result, it is hoped that future cases will be easier to diagnose with a DNA test.

Large clinical trial to test new device for detecting Barrett's oesophagus

CANCER RESEARCH UK has launched a large multi-centre trial to test a new device for detecting Barrett's oesophagus - a condition that puts sufferers at increased risk of developing cancer of the oesophagus, one of the most deadly cancers.

Microglia prune connections between neurons

Gardeners know that some trees require regular pruning: some of their branches have to be cut so that others can grow stronger. The same is true of the developing brain: cells called microglia prune the connections between neurons, shaping how the brain is wired, scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, discovered.

Male infertility cause found in defective gene

Researchers have found a new cause of infertility that could allow millions of infertile couples around the world to have a child. The team found a common gene mutation that causes sperm to be far less able to swim through the mucus of the cervix and reach the egg.

Researchers develop way to uncover evolution of human cancer cells

A team of researchers led by scientists at the University of California, San Francisco has developed a way to uncover the evolution of human cancer cells, determining the order in which mutations emerge in them as they wend their way from a normal, healthy state into invasive, malignant masses.

Small 'antifreeze' molecules more effective in protecting proteins than larger ones

Scientists have made an important step forward in their understanding of cryoprotectants - compounds that act as natural 'antifreeze' to protect drugs, food and tissues stored at sub-zero temperatures.

New research helps explain how memories are stored at synapses

Have a tough time remembering where you put your keys, learning a new language or recalling names at a cocktail party? New research from the Lisman Laboratory at Brandeis University points to a molecule that is central to the process by which memories are stored in the brain. A paper published in the June 22 issue of the Journal of Neuroscience describes the new findings.

Copenhagen chemist reveals mechanism behind deadly infections

Anthrax, septicemia and meningitis are some of the planet's most deadly infections. In part because doctors lack basic insights to prevent and cure diseases caused by so called Gram-positive bacteria. Now, a chemist from the University of Copenhagen has revealed the mechanism behind these deadly infections.

AIS introduces Spectral karyotyping

AIS introduces Spectral karyotyping (SKY®) equipment, designed and manufactured by ASI, a leading developer of comprehensive solutions for pathology and cytogenetics. Spectral karyotyping (SKY®) is ASI’s novel addition to the cytogenetic tool kit. It is based on a unique electro-optical hardware that enables measuring the spectral image of a metaphase, previously stained, such that each chromosome class has a different color (created typically from different combinations of 5 or more basic dyes).

Ventana Medical receives FDA approval for new breast cancer genetic test

The U.S. Food and Drug Administration today approved a new genetic test that will help health care professionals determine if women with breast cancer are HER2-positive and, therefore, candidates for Herceptin, a commonly used breast cancer treatment.

Linkam tensile stage chosen to control stress in growth of human collagen by the University of Liverpool

Manufacturers temperature controlled microscopy, Linkam Scientific Instruments, have been chosen by the Physics Department of the University of Liverpool to study the effects of controlling stresses applied during the growth of collagen secreted from human fibroblast cells. The research goal of Senior Research Assistant, Dr Caroline Smith, and her colleagues at the University of Liverpool is to advance the treatment of tendon injuries by developing a method of growing oriented human collagen.
