NASA's SDO observes another mid-level solar flare

2013-05-23
(Press-News.org) An image, captured at 11:06 a.m. EDT on May 22, 2013, from the ESA/NASA Solar Heliospheric Observatory shows the conjunction of two coronal mass ejections streaming away from the sun. This image is what's known as a coronagraph, in which the light of the sun is blocked in order to make its dimmer atmosphere, the corona, visible.

The M7-class flare was also associated with a coronal mass ejection or CME, another solar phenomenon that can send billions of tons of particles into space. While this CME was not Earth-directed, it has combined with an earlier CME, and the flank of the combined cloud may pass Earth. Particles from the CME cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground.

University of Wisconsin chemists find new compounds to curb staph infection

2013-05-23
MADISON, Wis. – In an age when microbial pathogens are growing increasingly resistant to the conventional antibiotics used to tamp down infection, a team of Wisconsin scientists has synthesized a potent new class of compounds capable of curbing the bacteria that cause staph infections. Writing online in the Journal of the American Chemical Society, a group led by University of Wisconsin-Madison chemistry Professor Helen Blackwell describes agents that effectively interfere with the "quorum sensing" behavior of Staphylococcus aureus, a bacterium at the root of a host of ...

Depression linked to telomere enzyme, aging, chronic disease

2013-05-23
The first symptoms of major depression may be behavioral, but the common mental illness is based in biology — and not limited to the brain. In recent years some studies have linked major, long-term depression with life-threatening chronic disease and with earlier death, even after lifestyle risk factors have been taken into account. Now a research team led by Owen Wolkowitz, MD, professor of psychiatry at UC San Francisco, has found that within cells of the immune system, activity of an enzyme called telomerase is greater, on average, in untreated individuals with major ...

Study shows people can be trained to be more compassionate

2013-05-23
MADISON, Wis. – Until now, little was scientifically known about the human potential to cultivate compassion — the emotional state of caring for people who are suffering in a way that motivates altruistic behavior. A new study by researchers at the Center for Investigating Healthy Minds at the Waisman Center of the University of Wisconsin–Madison shows that adults can be trained to be more compassionate. The report, recently published online in the journal Psychological Science, is the first to investigate whether training adults in compassion can result in greater altruistic ...

New discovery in fight against deadly meningococcal disease

2013-05-23
"Neisseria meningitidis is an important human pathogen that can cause rapidly progressing, life threatening meningitis and meningococcal sepsis in humans," Professor Jennings said. "Until now we have not known how it attaches to the human host. It has been a long-standing mystery how it attaches to the airway to colonise" People can be carriers of the bug and not get any symptoms, while some people progress to invasive disease. To understand why, we need to know the detail of how the bacterium colonises the airway. Now that the pathway has been identified we can study ...

New screening approach uncovers potential alternative drug therapies for neuroblastoma

2013-05-23
Nearly two-thirds of patients with high-risk neuroblastoma —a common tumor that forms in the nerve cells of children—cannot be cured using tumor-killing cancer drugs. A study published by Cell Press in the May 23 issue of Chemistry & Biology reveals a new genomic approach to screen for compounds that could inhibit tumor growth by causing cancer cells to differentiate, or convert from immature cells to more specialized cell types. Using this screening method, the researchers identified a compound that causes neuroblastoma cells to differentiate, uncovering a promising new ...

White tiger mystery solved

2013-05-23
White tigers today are only seen in zoos, but they belong in nature, say researchers reporting new evidence about what makes those tigers white. Their spectacular white coats are produced by a single change in a known pigment gene, according to the study, appearing on May 23 in Current Biology, a Cell Press publication. "The white tiger represents part of the natural genetic diversity of the tiger that is worth conserving, but is now seen only in captivity," says Shu-Jin Luo of China's Peking University. Luo, Xiao Xu, Ruiqiang Li, and their colleagues advocate a proper ...

Defective cellular waste removal explains why Gaucher patients often develop Parkinson's disease

2013-05-23
Gaucher disease causes debilitating and sometimes fatal neurodegeneration in early childhood. Recent studies have uncovered a link between the mutations responsible for Gaucher disease and an increased risk of developing Parkinson's disease later in life. New research published online on May 23 in the Cell Press journal Cell Metabolism indicates that the neurodegeneration found in Gaucher disease stems from defects in processes that break down and remove unwanted material from cells. This defective trash removal in cells can lead to the toxic build-up of proteins found ...

Researchers identify new target to boost plant resistance to insects and pathogens

2013-05-23
Plants can't swat a bug or run away from one, but that doesn't mean that plants can't fight back. Plants have evolved unique and sophisticated immune systems to defend themselves against insects and pathogens. Plant hormones called jasmonates play an important role in this defense, but jasmonates have been found to also be important for plant growth. Now, researchers reporting in the May 23 issue of the Cell Press journal Molecular Cell have discovered a gene in the jasmonate pathway that controls plant defenses but does not play a detectable role in plant development. ...

New imaging techniques used to help patients suffering from epilepsy

2013-05-23
Toronto, May 23 2013 - New techniques in imaging of brain activity developed by Jean Gotman, from McGill University's Montreal Neurological Institute, and his colleagues lead to improved treatment of patients suffering from epilepsy. The combination of electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI) leads to more precise localization of the areas generating epileptic seizures, giving neurosurgeons a better understanding of the optimal ways of intervention, if appropriate. These results were presented at the 2013 Canadian Neuroscience Meeting, ...
