- Evolution of an outbreak: Complications from contaminated steroid injections
Magnetic resonance imaging at the site of injection of a contaminated lot of a steroid drug to treat symptoms such as back pain resulted in earlier identification of patients with probable or confirmed fungal spinal or paraspinal infection, allowing early initiation of medical and surgical treatment.
- A battery made of wood?
A sliver of wood coated with tin could make a tiny, long-lasting, efficient and environmentally friendly battery, say scientists.
- Drug shows surprising efficacy as treatment for chronic leukemia, mantle cell...
Clinical studies suggest that the novel, targeted agent ibrutinib shows real potential is a safe, effective, treatment for adults with chronic lymphocytic leukemia and for patients with mantle cell lymphoma.
- Mindfulness can increase wellbeing and reduce stress in school children
Mindfulness -- a mental training that develops sustained attention that can change the ways people think, act and feel -- could reduce symptoms of stress and depression and promote wellbeing among school children, according to a new study.
- Scientists identify emotions based on brain activity
For the first time, scientists have identified which emotion a person is experiencing based on brain activity. The study combines functional magnetic resonance imaging and machine learning to measure brain signals to accurately read emotions in individuals. The findings illustrate how the brain categorizes feelings, giving researchers the first reliable process to analyze emotions. Until now, research on emotions has been long stymied by the lack of reliable methods to evaluate them.
- New details about H7N9 influenza infections that suddenly appeared in China
Researchers have revealed new information about the latest strain of type A influenza, known as H7N9.
- Scientists date prehistoric bacterial invasion still present in today's plant...
How long ago did bacteria invade the one-celled ancestors of plants and animals to become energy-producing mitochondria and photosynthesizing chloroplasts? Researchers developed a statistical way to analyze the variation in genes common to mitochondria, chloroplasts and the eukaryotic nucleus to more precisely date these events. They found that the cyanobacterial invasion of plants took place millions of years more recently than thought.
- Metamorphosis of moon's water ice explained
Using data gathered by NASA's Lunar Reconnaissance Orbiter mission, scientists believe they have solved a mystery from one of the solar system's coldest regions -- a permanently shadowed crater on the moon. They have explained how energetic particles penetrating lunar soil can create molecular hydrogen from water ice. The finding provides insight into how radiation can change the chemistry of water ice throughout the solar system.
- A shot in the arm for old antibiotics
Slipping bacteria some silver could give old antibiotics new life, scientists report. This could pave the way for new therapies for drug-resistant and recurrent infections.
- Less is more: Novel cellulose structure requires fewer enzymes to process bio...
Improved methods for breaking down cellulose nanofibers are central to cost-effective biofuel production and the subject of new research. Scientists are investigating the unique properties of crystalline cellulose nanofibers to develop novel chemical pretreatments and designer enzymes for biofuel production from cellulosic -- or non-food -- plant-derived biomass.
