Two genes in mammalian cells act as gatekeepers for cellular longevity

In everything from yeast to primates, a significant decrease in calories can extend lifespan by as much as one-third. But getting under the hood of the molecular machinery that drives this longevity has remained elusive.

Re-engineered human T cells effectively target and kill cancerous B cells

Human white blood cells, engineered to recognize other malignant immune cells, could provide a novel therapy for patients with highly lethal B cell cancers such as acute lymphoblastic leukemia (ALL), according to researchers at Memorial Sloan-Kettering Cancer Center (MSKCC).

New cell death pathway involved in sperm development

Heavy and bulky sperm would not be good swimmers. To trim down, sperm rely on cell death proteins called caspases, which facilitate the removal of unwanted cellular material and radically remodel these cells into their sleek, light shape.

GlaxoSmithKline to pursue novel antibacterial research program for DOD

GlaxoSmithKline has announced that it has signed an agreement with the Defense Threat Reduction Agency (DTRA) of the U.S. Department of Defense (DOD), to identify and develop a new class of antibacterials targeting both Gram negative biothreats and conventional Gram negative hospital pathogens.

Chronic infection persists by targeting stromal cell network in lymphoid organs

One of the biggest challenges to treating infectious diseases and developing preventive vaccines is the ability of many chronic infections to suppress the immune T-cell response over time.

New technology for cancer screening listens for the signs of cancer

Cancer-sensing devices built as cheaply and efficiently as wristwatches - using many of the same operating principles - could change the way clinicians detect, treat and monitor cancer in patients.

Secrets of protein folding revealed

A team led by biophysicist Jeremy Smith of the University of Tennessee and Oak Ridge National Laboratory (ORNL) has taken a significant step toward unraveling the mystery of how proteins fold into unique, three-dimensional shapes.

Scientists learn three-dimensional structure of enzyme in unusual virus

Biologists have determined the three-dimensional structure of an unusual viral enzyme that is required in the assembly of new viruses.

Nanoparticle that delivers vaccines more effectively

Good news for public health: Bioengineering researchers from the EPFL in Lausanne, Switzerland, have developed and patented a nanoparticle that can deliver vaccines more effectively, with fewer side effects, and at a fraction of the cost of current vaccine technologies.

Mechanism for the in-vivo transport of siRNA

It all started with flowers: in the nineties of the last century Norwegian researchers discovered that additional copies of a particular gene in petunias inhibited its activity instead of reinforcing it as had been assumed.

Circulating fats kill transplanted pancreas cells

New findings by UT Southwestern Medical Center researchers show that a byproduct of cholesterol metabolism interferes with the beneficial effects estrogen has on the cardiovascular system, providing a better understanding of the interplay between cholesterol and estrogen in heart disease.
