Flat worms may hold key to immortality

Experts from Nottingham University created a colony of more than 20,000 flatworms from one original by chopping it into pieces and observing each section grow into a new complete worm. They believe that it could help scientists develop new methods to allow humans to stay younger for longer.

IOM report identifies options that could further improve information obtained from pediatric studies

Federal laws that motivate or require drug and biologic developers to conduct pediatric studies have yielded beneficial information to guide the use of medications in children, says a new report by the Institute of Medicine. Still, studies involving children continue to be limited, especially in certain areas such as medications' use in newborns and long-term safety and effectiveness in children.

KF's TBI research director to speak at Washington conference

Jordan Grafman, PhD, director of Traumatic Brain Injury Research at Kessler Foundation, is an invited speaker at The 2nd Annual Traumatic Brain Injury Conference on March 6, 2012, in Washington, DC. Dr. Grafman will describe the long-term cognitive and social consequences of traumatic brain injury.

Study examines mRNA transcripts in the sperm of fruitflies and humans

It had long been assumed that the human sperm cell's mission in life ended once it had transferred its freight of parental DNA to the egg. More recently however, other components of sperm have been implicated in fertilization, and perhaps even in subsequent embryonic development.

ACTB and ACTG1 actin genes cause Baraitser-Winter syndrome

Scientists from Seattle Children's Research Institute and the University of Washington, in collaboration with the Genomic Disorders Group Nijmegen in the Netherlands, have identified two new genes that cause Baraitser-Winter syndrome, a rare brain malformation that is characterized by droopy eyelids and intellectual disabilities.

Scientists develop safer and more accurate way to administer warfarin

A team of global scientists, led by researchers at Intermountain Medical Center in Salt Lake City, has developed a safer and more accurate way to administer warfarin, one of the most commonly prescribed but also potentially dangerous medications in the United States.

Springer adds 6 new quarterly clinical review journals to medicine portfolio

Springer is adding six new quarterly clinical review journals to its existing medicine portfolio in March 2012. These new journals will expand the publisher's medical specialty coverage, focusing on dermatology, geriatrics/gerontology, nutrition, obesity, obstetrics/gynecology and respiratory care.

WUSM to study children with weakened immune systems

Not all viruses make us sick. But which ones are friends and which ones are foes? Researchers at Washington University School of Medicine in St. Louis have received a five-year, $3.3 million grant to study children with weakened immune systems to identify the viruses that make children sick.

Researchers discover connection between early humans and Neanderthals' genome

A striking discovery in the study of human genetics was the focus of the most-visited press release posted on EurekAlert! in 2011. Researchers found that part of the non-African human X chromosome came from Neanderthals, confirming that they interbred with early human populations.

Scientists demonstrate how immortal flatworm overcomes aging process

Researchers from The University of Nottingham have demonstrated how a species of flatworm overcomes the ageing process to be potentially immortal.

Aurora-A protein blocks proper functioning of tumor-suppressor p73

A protein abundantly found in treatment-resistant cancers holds an important tumor-suppressor out of the cell nucleus, where it would normally detect DNA damage and force defective cells to kill themselves, a team of scientists reports in the current Cancer Cell.

Researchers identify elusive gene responsible for TAR syndrome

Researchers have identified an elusive gene responsible for Thrombocytopenia with Absent Radii (TAR), a rare inherited blood and skeletal disorder. As a result, this research is now being transformed into a medical test that allows prenatal diagnosis and genetic counselling in affected families.

Study finds genetic variants that elevate risk for skin lesions in people exposed to arsenic

One of the first large-scale genomic studies conducted in a developing country has discovered genetic variants that elevate the risk for skin lesions in people chronically exposed to arsenic. Genetic changes found near the enzyme for metabolizing the chemical into a less toxic form can significantly increase an individual's risk for developing arsenic-related disease.

Combined bioactive peptides successfully stimulate wound healing

Researchers have combined bioactive peptides to successfully stimulate wound healing. The in vitro and in vivo study, published today in PLoS ONE, demonstrates that the combination of two peptides stimulates the growth of blood vessels and promotes re-growth of tissue. Further development of these peptides could lead to a new treatment for chronic and acute wounds.
