Making connections the key to overcoming shame

It would be difficult to find someone who has never felt shame in their life. But how does one overcome a prolonged feeling of being trapped in shame? University of Alberta researcher Jessica Van Vliet's study, published in the British Psychological Society journal, Psychology and Psychotherapy: Theory, Research and Practice, indicates that, while it may seem difficult when one is stuck in shame,...

Measuring nitrate concentrations in leafy green vegetables

Leafy green vegetables such as lettuce, Asian greens, and spinach can accumulate high concentrations of nitrate-nitrogen (NO3-N), which are potentially harmful if consumed by humans. Measuring NO3-N concentration in plant tissue requires sophisticated equipment and trained technicians and can be time-consuming, expensive, and impractical outside of a laboratory setting. Researchers undertook a...

Mother knows best

Scientists have found new evidence to explain how female insects can influence the father of their offspring, even after mating with up to ten males. A team has found that female crickets are able to control the amount of sperm that they store from each mate to select the best father for their young.The research suggests females may be using their abdominal muscles to control the amount of sperm...

MU researcher uses bacteria to make radioactive metals inert

The Lost Orphan Mine below the Grand Canyon hasn't produced uranium since the 1960s, but radioactive residue still contaminates the area. Cleaning the region takes an expensive process that is only done in extreme cases, but Judy Wall, a biochemistry professor at the University of Missouri College of Agriculture, Food and Natural Resources, is researching the use of sulfate-reducing bacteria to...

NASA Approves X-ray Space Mission

NASA recently confirmed that the Nuclear Spectroscopic Telescope Array, or NuSTAR, mission will launch in August 2011. NuSTAR will carry the first high-energy X-ray focusing telescopes into orbit, providing a much deeper, clearer view of energetic phenomena such as black holes and supernova explosions than any previous instrument has provided in this region of the electromagnetic...

New Biosensor Can Detect Bacteria Instantaneously

Researchers in Spain have developed a biosensor that can immediately detect very low levels of Salmonella typhi, the bacteria that causes typhoid fever. The technique uses carbon nanotubes and synthetic DNA fragments that activate an electric signal when they link up with the...

New biosensor can detect bacteria instantaneously

A research group from the Rovira i Virgili University in Tarragona has developed a biosensor that can immediately detect very low levels of Salmonella typhi, the bacteria that causes typhoid fever. The technique uses carbon nanotubes and synthetic DNA fragments that activate an electric signal when they link up with the pathogen.

New recommendations can help health providers prepare for electronic record push

A new framework of recommendations created by health informatics researchers may help doctors and hospitals prepare for a federal initiative to expand the use of electronic health records. The recommendations from faculty at The University of Texas Health Science Center at Houston, the Michael E. DeBakey Veterans Affairs Medical Center and Baylor College of Medicine appear in a commentary in the...

New vaccine shows promise for COPD patients at risk for pneumonia

A new vaccine against pneumonia may offer better protection from chronic obstructive pulmonary disease (COPD) patients than the currently accepted vaccine, according to recent research that will be published in the Sept. 15 issue of the American Journal of the Respiratory and Critical Care Journal, a publication of the American Thoracic Society.

Organic weed control for dandelions

Spring and summer often find homeowners out in their yards, busily attempting to control the onslaught of dandelions in a quest for green, weed-free lawns. Responding to criticism that synthetic herbicides can be harmful to the environment, researchers around the world are experimenting with organically derived weed control methods. Researchers recently studied the effectiveness of pesticide-free...

Patients With Interstitial Lung Disease Need Not Avoid Air Travel, Study Finds

Patients with interstitial lung disease (ILD) are often concerned about the occurrence of pneumothorax (collapsed lung) or other life-threatening events during air travel. However, new research shows that, even in ILD with a high prevalence of spontaneous pneumothorax, such as lymphangioleiomyomatosis (LAM), there is a relatively low risk of these events...

Peer Review Survey 2009: Preliminary findings

Should peer review detect fraud and misconduct? What does it do for science and what does the scientific community want it to do? Will it illuminate good ideas or shut them down? Should reviewers remain anonymous? These questions are raised by one of the largest ever international surveys of authors and reviewers, the Peer Review Survey 2009, whose preliminary findings are released today.

Plants on steroids: Key missing link discovered

Researchers have discovered a key missing link in the so-called signaling pathway for plant steroid hormones. This discovery marks the first such pathway in plants for which all the steps have been identified. Since this pathway shares many similarities with pathways in humans, the discovery not only could lead to the genetic engineering of improved crops, but also could be a key to understanding...

Plants On Steroids: Key Missing Link Discovered Could Improve Understanding of Major Human Diseases

Researchers have discovered a key missing link in the so-called signaling pathway for plant steroid hormones. This discovery marks the first such pathway in plants for which all the steps have been identified. Since this pathway shares many similarities with pathways in humans, the discovery not only could lead to the genetic engineering of improved crops, but also could be a key to understanding...

Pollution From California Wildfires Spreads Across The United States

Beginning August 26, 2009, and continuing into September 2009, a large wildfire in the Angeles National Forest north of Los Angeles known as the Station Fire burned more than 140,000 acres through September 3. Carbon monoxide in the smoke from this large fire was lofted as high as 8.3 kilometers (27,000 feet) into the atmosphere, where it was observed by JPL's Atmospheric Infrared Sounder (AIRS)...
