Cancer cells spread by releasing 'bubbles', according to an MUHC study
A new fundamental mechanism of how tumour cells communicate has just been discovered by the team of Dr. Janusz Rak at the Research Institute of the McGill University Health Centre (MUHC) in collaboration with Dr Guha from the University of Toronto. view more (2008-04-22)
Proteomics Study Yields Clues As To How Tuberculosis Might Be Thwarting The Immune System
A link between the immune system and the self-cleaning system by which biological cells rid themselves of obsolete or toxic parts may one day yield new weapons in the fight against tuberculosis and other deadly infectious diseases. view more (2008-11-06)
Singapore nanotechnology combats fatal brain infections
Doctors may get a new arsenal for meningitis treatment and the war on drug-resistant bacteria and fungal infections with novel peptide nanoparticles developed by scientists at the Institute of Bioengineering and Nanotechnology (IBN) of Singapore and reported in Nature Nanotechnology. view more (2009-06-29)
Nanoelectronic transistor combined with biological machine could lead to better electronics
If manmade devices could be combined with biological machines, laptops and other electronic devices could get a boost in operating efficiency. view more (2009-08-11)
Self-Assembled Materials Form Mini Stem Cell Lab
Imagine having one polymer and one small molecule that instantly assemble into a flexible but strong sac in which you can grow human stem cells, creating a sort of miniature laboratory. view more (2008-03-28)
Figuring out function from bacteria's bewildering forms
The constellation of shapes and sizes among bacteria is as remarkable as it is mysterious. Why should Spirochaeta halophila resemble a bedspring coil, Stella a star and Clostridium cocleatum a partly eaten donut? No one really knows. view more (2006-07-19)
'Electronic switch' opens doors in rheumatoid joints
A breakthrough in understanding the way atoms move across cell membranes in the human body could pave the way for the development of new treatments for inflammatory diseases such as rheumatoid arthritis. view more (2008-01-03)
Zooming in on the protein-conducting channel
Researchers have gained the most detailed view yet of the heart of the translocon, a channel through which newly constructed proteins are inserted into the cell membrane. view more (2005-11-17)
Researchers develop better membranes for water treatment, drug delivery
Researchers at the University of Illinois have developed a new generation of biomimetic membranes for water treatment and drug delivery. view more (2007-11-30)
Molecular mechanism provides intra-cellular traffic signal
Researchers at the University of Illinois at Chicago have found that intra-cellular trafficking is tightly coordinated for maximum flow through cellular compartments - much as vehicles on a crowded road are allowed to pass quickly through a succession of green traffic lights. view more (2006-10-18)
Novel structure proteins could play a role in apoptosis
Isoforms from Novel Structure Proteins (NSP), a new family of genes discovered by researchers in the Sbarro Institute for Cancer Research and Molecular Medicine in Temple University's College of Science and Technology, could be involved in apoptosis or programmed cell death. view more (2008-07-25)
Findings relate aspirin-induced ulcers, hearing loss
It's well known that high doses of aspirin can cause ulcers and temporary deafness, but the biochemical mechanism responsible for these phenomena has never been deciphered. view more (2005-09-20)
New technique helps researchers determine amino-acid charge
Measurements of the ion-current through the open state of a membrane-protein's ion channel have allowed scientists at the University of Illinois at Urbana-Champaign to obtain a detailed picture of the effect of the protein microenvironment on the affinity of ionizable amino-acid residues for protons. view more (2005-12-15)
Chromosomes dance and pair up on the nuclear membrane
Meiosis - the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell - is a major crossroads in all organisms reproducing sexually. view more (2009-11-16)
Researchers identify mechanism that helps bacteria avoid destruction in cells
Infectious diseases currently cause about one-third of all human deaths worldwide, more than all forms of cancer combined. Advances in cell biology and microbial genetics have greatly enhanced understanding of the cause and mechanisms of infectious diseases. view more (2009-10-12)
UCLA chemists' study of protein may provide insights into heart disease and cancer
UCLA chemists studying a protein associated with a rare genetic disease may also be gaining insights into cancer and heart disease. view more (2006-08-11)
Researchers map infectious hepatitis B virus
Using electron cryomicroscopy and computer image analysis, the scientists visualized two intermediate forms of the virus that exist within infected cells. In addition, they were able to determine a three-dimensional map by analysis of infectious hepatitis B virus isolated from patient blood samples. view more (2006-06-26)
New research demonstrates bone-marrow derived stem cells can reverse genetic kidney disease
The discovery that bone-marrow derived stem cells can regenerate damaged renal cells in an animal model of Alport syndrome provides a potential new strategy for managing this inherited kidney disease and offers the first example of how stem cells may be useful in repairing basement membrane matrix defects and restoring organ function. view more (2006-04-25)
Fantastic plastic could cut CO2 emissions and purify water
A new membrane that mimics pores found in plants has applications in water, energy and climate change mitigation. view more (2007-10-12)
Unlocking biological secrets: Cornell scientists build 'nano-keys' to bind cell receptors and trigger allergic reactions
The tumblers of life continue to click as Cornell University researchers have fabricated a set of "nano-keys" on the molecular scale to interact with receptors on cell membranes and trigger larger-scale responses within cells - such as the release of histamines in an allergic response. view more (2006-02-17)
