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.

NPL scientists mimick the ways viruses infect human cells and deliver genetic material

Scientists at the National Physical Laboratory (NPL) have mimicked the ways viruses infect human cells and deliver their genetic material. The research hopes to apply the approach to gene therapy - a therapeutic strategy to correct defective genes such as those that cause cancer.

Commercial blood serum antibody tests cost-effective, not accurate for active TB

Commercial blood serum antibody tests—widely used in India and other developing countries to diagnose active tuberculosis—are not accurate or cost-effective, according to an analysis by researchers at the Johns Hopkins Bloomberg School of Public Health, the University of Washington School of Public Health and McGill University.

New findings on human brain's photosensitivity

Valkee, inventor of the world's first bright-light headset, and scientists from the University of Oulu will present new findings on human brain's photosensitivity at the Scandinavian Physiology Society Annual Meeting 2011, August 12-14.

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 insights into cancer-induced intussusceptive angiogenesis

Researchers have gained a new understanding of the way in which growing tumors are fed and how this growth can be slowed via angiogenesis inhibitors that eliminate the blood supply to tumors. This represents a step forward towards developing new anti-cancer drug therapies.

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.

New fluorescent tool can track mysterious workings of cellular RNAs

The ability to tag proteins with a green fluorescent light to watch how they behave inside cells so revolutionized the understanding of protein biology that it earned the scientific teams who developed the technique Nobel Prizes in 2008.

Study reveals several compounds that block cancer cell invasion

Metastasis-the spread of cancer from the place where it first started to another place in the body-is the most common reason that cancer treatments fail. To metastasize, some types of cancer cells rely on invadopodia, cellular membrane projections that act like feet, helping them "walk" away from the primary tumor and invade surrounding tissues.

WHO warns against blood test kits for tuberculosis

According to a World Health Organization (WHO) warning Sunday, the widely used blood tests to detect tuberculosis (TB) are “dangerous” to patients because they are unreliable and can produce incorrect results. The WHO announced that it will issue an unprecedented recommendation against using such tests for the infectious lung disease that affects some 14 million people worldwide. As much as a third of the world's population is thought to harbor the bacteria that cause TB.

Promising compounds for new anti-obesity drugs

Though it generally is known that obesity dramatically increases the risk for type 2 diabetes, the biological mechanisms for that connection still are unclear.

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.

Light-switching complex could help detect signs of Alzheimer's disease

A breakthrough in sensing at Rice University could make finding signs of Alzheimer's disease nearly as simple as switching on a light.

New method to study neuronal activity in the deepest layers of the cortex

Visual and tactile objects in our surroundings are translated into a perception by complex interactions of neurons in the cortex. The principles underlying spatial and temporal organization of neuronal activity during decision-making and object perception are not all understood yet.

New insights into how cancer cells can maintain resistance to chemotherapy

Researchers from the Royal College of Surgeons in Ireland (RCSI) have conducted a study which reveals new insights into how cancer cells can maintain a resistance to chemotherapy resulting in cancer relapse.

Research provides new insights into how cilia are assembled on the cell surface

Body cells detect signals that control their behavior through tiny hairs on the cell surface called cilia. Serious diseases and disorders can result when these cilia do not work properly.

Novel FRET biosensor allows measurement of intraorganellar glutathione potentials in living cells

In work published in the June 2011 issue of Experimental Biology and Medicine, Kolossov, Spring and their co-investigators - a multidisciplinary team within the Institute for Genomic Biology at the University of Illinois - have transferred the concept of redox-sensitive Green Fluorescent Proteins (GFPs) to a quantitative F-rster resonance energy transfer (FRET) imaging platform.

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.
