Magnetic field with the edge!

This study overturns a dominant six-decade old notion that the giant magnetic field in a high intensity laser produced plasma evolves from the nanometre scale. Instead the field actually originates at macroscopic scales defined by the boundaries of the electron beam that is propagating in the plasma. This could alter our understanding of magnetic fields in astrophysics and laser fusion and may...

Mayo Clinic and TGen ID potential targets for the most-deadly form of pancreatic cancer

In what is believed to be the most comprehensive analysis of adenosquamous cancer of the pancreas (ASCP), the Mayo Clinic and TGen team identified, in preclinical models, therapeutic targets for this extremely fast-moving and deadly form of pancreatic cancer, and identified already available cancer inhibitors originally designed for other types of cancer, according to a study published today in...

NASA's Aqua satellite finds Rene barely a depression battered by wind shear  

Tropical Depression Rene continues to be the victim of strong wind shear and forecasters anticipate it will lead to the storm's demise in the next couple of days. NASA's Aqua satellite viewed the storm in infrared light to find wind shear was pushing Rene's strongest storms away from the center, preventing the storm from re-organizing and strengthening.

Neural cartography

A new x-ray microscopy technique could help accelerate efforts to map neural circuits and ultimately the brain itself. Combined with artificial intelligence-driven image analysis, researchers used XNH to reconstruct dense neural circuits in 3D, comprehensively cataloging neurons and even tracing individual neurons from muscles to the central nervous system in fruit flies.

No benefit from drug used to reduce heart disease in kidney patients

Following a large, seven-year clinical trial, researchers have shown the drug, lanthanum carbonate, does not reduce the risk of cardiovascular disease in patients with chronic kidney disease. The drug has been commonly prescribed to this patient group to help reduce the risk of both bone disease and cardiovascular disease.

Not so similar: Depression, but not anxiety, linked with inflammation and metabolic change

Anxiety and depression are often linked and assumed to be closely related, but now research has shown for the first time that depression and anxiety have different biochemical associations with inflammation and lipid (fat) metabolism. This indicates that different, more targeted treatments may be possible to treat anxiety and depression. This work is presented at the ECNP Congress.

On the road to conductors of the future

Superconducting wires can transport electricity without loss. This would allow for less power production, reducing both costs and greenhouse gasses. Unfortunately, extensive cooling stands in the way, because existing superconductors only lose their resistance at extremely low temperatures. In the journal Angewandte Chemie, scientist have now introduced new findings about hydrogen sulfide in the...

Painless paper patch test for glucose levels uses microneedles

Researchers at The University of Tokyo have developed a microneedle patch for monitoring glucose levels using a paper sensor. The device painlessly monitors fluid in the skin within seconds. Anyone can use the disposable patch without training, making it highly practical. Additionally, fabrication is easy, low cost, and the glucose sensor can be swapped for other paper-based sensors that monitor...

Physicists discover new magnetoelectric effect

A special material was found, which shows a surprising new effect: Its electrical properties can be controlled with a magnetic field. This effect works completely differently than usual. It can be controlled in a highly sensitive way.

Possible genetic link found between hypothyroidism and development of canine T-zone lymphoma

A genetic mutation might be the reason dogs with hypothyroidism are less likely to develop T-zone lymphoma (TZL). That's the finding from Morris Animal Foundation-funded researchers at Colorado State University who tried to identify genetic risk factors for TZL using a genome-wide association study (GWAS) and subsequent targeted sequencing. They recently published their results in the journal BMC...

Possible marker of life spotted on venus

An international team of astronomers today announced the discovery of a rare molecule -- phosphine -- in the clouds of Venus. On Earth, this gas is only made industrially or by microbes that thrive in oxygen-free environments. Astronomers have speculated for decades that high clouds on Venus could offer a home for microbes -- floating free of the scorching surface but needing to tolerate very high...
