Humans helped vultures colonize the Canary Islands
The Egyptian vulture population of the Canary Islands was established following the arrival of the first human settlers who brought livestock to the islands.

New labeling method expands ability to read DNA modification
Researchers have developed a method for labeling and mapping a

Pomegranate juice components inhibit cancer cell migration; in vivo testing planned
Researchers have identified components in pomegranate juice that seem to inhibit movement of cancer cells and weaken their attraction to chemical signal that has been shown to promote metastasis of prostate cancer to bone.

'Grow your own transplant' may be possible for men with type 1 diabetes
Men with type 1 diabetes may be able to grow their own insulin-producing cells from their testicular tissue, say Georgetown University Medical Center researchers who presented their findings today at the American Society of Cell Biology 50th annual meeting in Philadelphia.

Demise of large satellite may have led to the formation of Saturn's rings and inner moons
Simulations performed at Southwest Research Institute may explain how Saturn's majestic rings and icy inner moons formed following the collision of a Titan-sized satellite with the planet, according to a paper published in Nature magazine's Dec.

Canadian scientists identify a spontaneously chain-reacting molecule
The paper describes, for the first time, a simple molecule that each time it chemically reacts with a surface prepares a hospitable neighboring site at which the next incoming molecule reacts.

Ultrasonography capable of detecting endometrial cancer before symptoms are evident in postmenopausal women
Transvaginal ultrasound screening (TVS) has good (80-90 percent) sensitivity and specificity at detecting endometrial cancer before symptoms appear in postmenopausal women, according to the first large-scale study to assess the performance of TVS screening for endometrial cancer.

UCR scientists identify pomegranate juice components that could stop cancer from spreading
Researchers at the University of California, Riverside have identified components in pomegranate juice that both inhibit the movement of cancer cells and weaken their attraction to a chemical signal that promotes the metastasis of prostate cancer to the bone.

Human spermatogonial stem cells become insulin-secreting pancreatic cells in lab
Insulin-secreting pancreatic islet cells have been generated from human spermatogonial stem cells (SSCs) directly isolated from human testicular tissue.

Tracing microbes between individuals towards personalized oral health care
The human body harbors a complex ecosystem of microbes recognized as having a role in health and disease.

Parasite and bacterium illustrate convergent evolution: Both hijack cells' 'post office'
Protozoan parasite Toxoplasma gondii and pathogenic bacterium Chlamydia trachomatis exemplify convergent evolution, development of similar biological trait in unrelated lineages, according to research at the American Society of Cell Biology's 50th annual meeting.

Ubiquitous sugar molecule could be key to repairing deep wound without scarring
Blocking fragments of the sugar molecule hyaluronan that triggers inflammation could be the key to robust healing and less scarring in deep wounds.

Stem cells turned into complex, functioning intestinal tissue in lab
For the first time, scientists have created functioning human intestinal tissue in the laboratory from pluripotent stem cells.

'Discovery as an Occupation: Conversations with Cell Biologists'
An informal, good-natured, and intimate program that will use a classic

Studies detail triumphs, troubles of African innovators creating products for local health needs
Details the first research offering broad range evidence and concrete examples of African science innovation to address local health concerns.

Protein offers new clue to cause and treatment for kidney disease
University of Alabama at Birmingham researchers have pinpointed a protein that compromises the kidney's filtering ability, causing nephrotic syndrome, and demonstrated that a naturally occurring precursor of an acid in the body offers potential for treating some forms of the condition.

MGH researchers develop faster method of engineering zinc-finger nucleases
A team led by Massachusetts General Hospital researchers has developed a faster way to engineer synthetic enzymes that target specific DNA sequences for inactivation, repair or alteration.
