Intellectual resources may help soldiers stave off post-traumatic stress disorder
Greater intellectual resources may, according to a new study of Vietnam veterans, help buffer soldiers from developing post-traumatic stress disorder (PTSD) after combat.
Adult bone marrow stem cells can become blood vessels
Researchers at the University of Minnesota Stem Cell Institute (SCI) have demonstrated, for the first time, the ability of adult bone marrow stem cells to expand in vitro as endothelial cells (which line blood- and lymphatic vessels) and then engraft in vivo and contribute to new growth of blood vessels (neoangiogenesis).
Re-designed care could reduce postnatal depression
A UK study in this week's issue of THE LANCET highlights how a new model of postnatal care led by midwives and tailored to meet individual needs could reduce the risk of mental illness among women in the first four months after childbirth.

Research uncovers new treatment target for cystic fibrosis patients' lung infection
In experiments that could lead to an important advance in treating cystic fibrosis, the most common lethal genetic illness among whites, U.S. and European scientists have discovered that the chief bacteria infecting CF patients' lungs can live without oxygen.
Luring lightening away from sports crowds
Supersonic jets of salty water squirted towards storm clouds could deflect lightening strikes away from crowded sports fields or open air concerts.

Getting something out of nothing
Researchers get energy from empty space. For the first time, a physicist in California has exploited a strange force, called the Casimir effect, to move tiny gold plates past each other.
New test detects colon cancer gene
HHMI researchers have developed a technique that detects small amounts of a colon-cancer-triggering gene in stool samples.
Stem cell study provides new clues to origin of Down syndrome
Using stem cells as a window to the earliest developmental processes in the human brain, scientists have found that a group of genes critical for brain development is selectively disrupted in Down syndrome.
Roll call: Study shows how bacteria signal a quorum
Scientists have identified a molecule that allows bacteria to send signals between species, a discovery that may eventually lead to new drugs designed to disrupt bacterial communication.
Initial clinical study shows safety and bioactivity of cancer vaccine
A new phase I clinical trial of a prostate cancer vaccine developed at Duke University Medical Center has shown that the vaccine made from the patient's own dendritic cells causes no adverse side effects.
Stool test for colon cancer reported by Kimmel Cancer Center at Johns Hopkins
Scientists at the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins* have developed a safe and reliable stool test that can detect the earliest, curable stages of colon cancer.
What role for commercial banks in the evolution of Russian capitalism?
Russia's commercial banks have played a relatively minor role in the country's economic development since the collapse of the Soviet Union.
Scientists use llama droppings to help combat water pollution
Scientists from Newcastle University are using llama droppings to help combat environmental problems caused by polluted water seeping from abandoned silver and tin mines in the Bolivian Andes.
Hypoxic mucus favors Pseudomonas infections in cystic fibrosis
Cystic fibrosis (CF) is life-threatening primarily because the lungs of affected individuals are subject to persistent and intractable infections, typically with Pseudomonas aeruginosa.
Water lily may provide a 'missing link' in the evolution of flowering plants
Biologists have discovered that the water lily may be a critical
Study reveals new information on how viruses enter cells
A detailed look at a syringe-like structure designed to inject viral DNA into a host cell reveals a unique and complex entry scheme for viruses.
Worldwide hunger more a political problem, study finds
The key to helping developing countries with hungry populations is not just providing more food - it is eliminating war and providing stable, democratic governments.
Earth scientists use fractals to measure and predict natural disasters
Predicting the size, location, and timing of natural hazards is virtually impossible, but now, earth scientists are able to forecast hurricanes, floods, earthquakes, volcanic eruptions, wildfires, and landslides using fractals.
Rollins family gives $4.2 million to establish new Office of Public Health Preparedness at Emory
Former assistant Surgeon General of the United States Dr. Ruth Berkelman has been named to head a new program at Emory University that will address critical needs in the nation's public health system revealed by the terrorist attacks of last fall.
A novel cardiac glycogen storage disease
Glycogen storage disorders are inborn errors of metabolism that typically affect the cellular architecture and function of the liver or kidney.
Drug-free therapy gives patients reprieve from panic disorder
A recent study showed that four out of five patients suffering from panic disorder remained symptom-free six months after they stopped taking medication to treat the often-debilitating illness.
New understanding of complex virus nano-machine for cell puncturing and DNA delivery
Researchers have learned how the bacterial virus, bacteriophage T4, attacks its host, the E. coli bacterium.
Sandia to host electrical energy storage systems applications and technologies conference
Sandia National Laboratories, a Department of Energy national laboratory, will co-host the Conference on Electrical Energy Storage Applications and Technologies (EESAT2002), April 15-17.

Now Playing: TED Radio Hour

Why do we revere risk-takers, even when their actions terrify us? Why are some better at taking risks than others? This hour, TED speakers explore the alluring, dangerous, and calculated sides of risk. Guests include professional rock climber Alex Honnold, economist Mariana Mazzucato, psychology researcher Kashfia Rahman, structural engineer and bridge designer Ian Firth, and risk intelligence expert Dylan Evans.

#541 Wayfinding
These days when we want to know where we are or how to get where we want to go, most of us will pull out a smart phone with a built-in GPS and map app. Some of us old timers might still use an old school paper map from time to time. But we didn't always used to lean so heavily on maps and technology, and in some remote places of the world some people still navigate and wayfind their way without the aid of these tools... and in some cases do better without them. This week, host Rachelle Saunders...

Dolly Parton's America: Neon Moss
Today on Radiolab, we're bringing you the fourth episode of Jad's special series, Dolly Parton's America. In this episode, Jad goes back up the mountain to visit Dolly's actual Tennessee mountain home, where she tells stories about her first trips out of the holler. Back on the mountaintop, standing under the rain by the Little Pigeon River, the trip triggers memories of Jad's first visit to his father's childhood home, and opens the gateway to dizzying stories of music and migration.
