Scientists develope a new model of artificial canine skin
Researchers at UNIVET, a spin-off of the Universitat Autònoma de Barcelona, in cooperation with the animal nutrition company Affinity Petcare, have developed an artificial cellular model which faithfully reproduces the characteristics of dog's skin and which will allow, therefore, the carrying out of various lines of research related to... view more...

Nicotine rush hinges on sugar in neurons
When nicotine binds to a neuron, how does the cell know to send the signal that announces a smoker's high" view more (2007-07-23)
Biofuel cells without the bio cells
Proteins keep cells humming. Some are enzymes that taxi electrons to chemicals outside the cell, to discharge excess energy generated during metabolism. This maintains energy flow in the cell and, in turn, keeps the cell alive. view more (2006-10-18)
Rac 1 and 2, two proteins essential to triggering of the immune response
The dendritic cells act as the body's sentries, standing guard around the clock. As soon as they detect a potential enemy, they alert the T cells, whose role is to defend the body. At the Institut Curie, CNRS researchers in an Inserm laboratory have filmed the encounter of dendritic cells and T cells. They have shown that this "rendez-vous",... view more... (2004-08-23)
Nitrates in vegetables protect against gastric ulcers
Fruits and vegetables that are rich in nitrates protect the stomach from damage. This takes place through conversion of nitrates into nitrites by the bacteria in the oral cavity and subsequent transformation into biologically active nitric oxide in the stomach. view more (2008-05-08)
Turn back, wayward axon
To a growing axon, the protein RGMa is a "Wrong Way" sign, alerting it to head in another direction. As Hata et al. demonstrate in the March 9, 2009 issue of the Journal of Cell Biology, translating that signal into cellular action requires teamwork from two receptors. view more (2009-03-09)
Leeds awarded £2.3m to map protein structure
The University of Leeds has been awarded £2.3m to map the structure of membrane proteins, so that drugs can be designed to more effectively target widespread diseases including diabetes, cancer and bacterial infections. The funds were awarded by the Biotechnology and Biological Sciences Research Council as part of a £6.8m grant to the... view more... (2004-04-17)
Models of eel cells suggest electrifying possibilities
Engineers long have known that great ideas can be lifted from Mother Nature, but a new paper by researchers at Yale University and the National Institute of Standards and Technology (NIST) takes it to a cellular level. view more (2008-10-03)
Dominant cholesterol-metabolism ideas challenged by new research
A team of researchers investigating cholesterol and lipid transport has performed experiments that cast serious doubt on the dominant hypothesis of how the body rids its cells of "bad" cholesterol (LDL) and increases "good" cholesterol (HDL). view more (2007-08-16)
A fly lamin gene is both like and unlike human genes
Lamins are intermediate filament proteins that make up a matrix underlying the nuclear membrane. view more (2007-06-13)
Blocking a premature aging syndrome with anticancer drugs
A class of anticancer drugs currently being evaluated in phase 3 clinical trials may also be an effective treatment for Hutchinson-Gilford progeria syndrome (HGPS), a fatal genetic disorder that causes premature aging. view more (2005-08-30)
Membrane research opens window to benefits for plants, humans
A wilting, water-starved houseplant and flood-covered crops have something in common. That knowledge, gleaned from spinach and researchers on two continents, potentially could open the gate to advances in both plant and human health. view more (2005-12-21)
Alzheimer's: New findings resolve long dispute about how the disease might kill brain cells
For a decade, Alzheimer's disease researchers have been entrenched in debate about one of the mechanisms believed to be responsible for brain cell death and memory loss in the illness. view more (2009-04-16)
Cucumber Versus Cucumber
Marine invertebrate called sea cucumber resembles vegetable cucumber by not only shape, but also by some metabolites. The substances produced by the animal can affect the growth of the plant. This study was conducted by Russian biochemists and supported by the RFBR. view more (2004-11-15)
Einstein researchers discover important clue to the cause of Parkinson's disease
A glitch in the mechanism by which cells recycle damaged components may trigger Parkinson's disease, according to a study by scientists at the Albert Einstein College of Medicine of Yeshiva University. view more (2008-01-03)
New mechanism links smoking to lung damage
In the August 7, 2007, issue of PLoS One, researchers show how a poorly understood and previously unsuspected mechanism may be the key to understanding how life-style associated forms of oxidative stress, such as exposure to cigarette smoke, damage cells in the lungs. view more (2007-08-07)
Caltech biologists spy on the secret inner life of a cell
The transportation of antibodies from a mother to her newborn child is vital for the development of that child's nascent immune system. view more (2008-10-13)
Purdue researchers obtain a snapshot clarifying how materials enter cells
A group of Purdue University researchers has captured a key step in the metabolic process that allows materials, such as nutrients and drug treatments, to move in and out of cells. view more (2007-12-03)
Improving Fuel Cell Durability: Research into Better Fuel Cell Materials and Designs Starts with Studying Failures
Fuel cells can be expensive and they typically don't last as long as their internal combustion counterparts. view more (2007-11-29)
Researchers identify new, cancer-causing role for protein
The mainstay immune system protein TRAF6 plays an unexpected, key role activating a cell signaling molecule that in mutant form is associated with cancer growth, researchers at The University of Texas M. D. Anderson Cancer Center report in the Aug. 28 edition of Science. view more (2009-08-28)
