Diet rich in fat, sugar and cholesterol a potential risk factor for Alzheimer's disease

Mice that were fed a diet rich in fat, sugar and cholesterol for nine months developed a preliminary stage of the morbid irregularities that form in the brains of Alzheimer's patients.

Crossing scientific boundaries to understand the rejection of drugs

A physicist from The University of Nottingham and a mathematical modeller from The University of Southampton are joining forces in the hope of answering a biological mystery - how do our bodies reject some of the drugs that are sent to cure us?

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.

Advance in K-Ras-mutated cancer research

A team of cancer researchers from several Boston academic medical centers has discovered a potential treatment for a group of tumors that have resisted previous targeted therapy approaches.

Study identifies genetic variants giving rise to differences in metabolism

Common genetic polymorphisms induce major differentiations in the metabolic make-up of the human population, according to a paper published November 28 in the open-access journal PLoS Genetics.

Researchers discover genomic causes of acute lymphoblastic leukemia relapse

Scientists at St. Jude Children's Research Hospital have identified distinctive genetic changes in the cancer cells of children with acute lymphoblastic leukemia (ALL) that cause relapse.

Research identifies cell receptor as target for anti-inflammatory immune response

Cell reception. By comparing normal mice (left) with mice that are genetically engineered to lack certain receptors in their spleen (right), scientists have shown SIGNR1 receptors (blue) are required to facilitate an anti-inflammatory action.

Protein-misfolding accelerates yeast evolution

Under stress, yeast cells can unleash a remarkable mechanism based on protein-misfolding that gives them new characteristics without requiring genetic mutations.

Yale researchers find molecule that may help regulate how much animals and people eat

In the battle against obesity, Yale University researchers may have discovered a new weapon - a naturally occurring molecule secreted by the gut that makes rats and mice less hungry after fatty meals.

Researchers provide new evidence that aging can be slowed

New evidence may explain why it is that we lose not only our youthful looks, but also our youthful pattern of gene activity with age.

Clear seasonal variation in bacterial infections

In the same way that winter is commonly known to be the "flu season," a new study suggests that the dog days of summer may well be the "bacterial infection" season.

Scientists uncover new RNA processing mechanism and a new class of small RNAs

A very small fraction of our genetic material - about 2% - performs the crucial task scientists once thought was the sole purpose of the genome: to serve as a blueprint for the production of proteins, the molecules that make cells work and sustain life.

Researchers provide new insight into adaptive ability of cells

The Stowers Institute's Rong Li Lab has published findings that shed light on the ability of cells to adapt to disruptions to their basic division machineries - findings that may help explain how cancer cells elude the body's natural defense mechanisms or chemotherapy treatment.

Researchers identify a potentially universal mechanism of aging

Like our current financial crisis, the aging process might also be a product excessive deregulation.

Discovery of mechanism linking serotonin with regulation of food intake

Genetic mouse models have provided surprising insight into mechanisms linking serotoninergic compounds with the regulation of feeding behavior and body weight.

Nitric oxide can change computational ability of the brain

Research from the Medical Research Council (MRC) Toxicology Unit at the University of Leicester shows that nitric oxide (NO) can change the computational ability of the brain.

Mouse model of prion disease mimics diverse symptoms of human disorder

A comprehensive mouse model of inherited prion disease exhibits cognitive, motor, and neurophysiological deficits that bear a striking resemblance to the symptoms experienced by patients with the human version of "mad cow disease," Creutzfeldt-Jakob disease (CJD).

Researchers identify molecule that tells your brain your stomach is full

In studies with mice and rats, researchers have found that a chemical messenger called NAPE is made in the small intestine after the animals ate a greasy meal. After eating, NAPE - N-acylphosphatidylethanolamine, a mouthful in itself -- enters the blood and travels to the brain, where it quashes hunger signals.
