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...
Mediterranean and tropical biodiversity most vulnerable to human pressures
Animals in tropical and Mediterranean areas are the most sensitive to climate change and land use pressures, finds a new study by UCL researchers, published today in Nature Ecology & Evolution.
NASA catches development of eastern Atlantic's tropical storm Vicky
NASA's Aqua satellite analyzed a low-pressure area in the far eastern Atlantic Ocean, and it showed the system becoming more organized. Soon after Aqua passed overhead, the low became Tropical Depression 21. Hours later, the storm strengthened into Tropical Storm Vicky.
NASA night-time image shows Hurricane Paulette's large eye approach Bermuda
Night-time imagery from NASA-NOAA's Suomi NPP satellite showed Hurricane Paulette's large eye approaching the island of Bermuda. A Hurricane Warning is in effect for Bermuda.
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.
NASA's water vapor analysis of Tropical Storm Karina shows wind shear effects
When NASA's Aqua satellite passed over the Eastern Pacific Ocean, it gathered water vapor data on Tropical Storm Karina. The data showed that the storm was being affected by wind shear from the northeast, pushing the bulk of clouds to the southwest.
NASA-NOAA satellite helps confirm Teddy now a record-setting tropical storm
NASA-NOAA's Suomi NPP satellite provided an infrared image of Tropical Depression 20 in that helped confirm it organized and strengthened into Tropical Storm Teddy. Teddy, which has broken a hurricane season record, is expected to become a major hurricane later in the week, according to the National Hurricane Center (NHC).
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.
New insight into how muscles and fat cells work together to make you more fit
Scientists in Denmark and Brazil find evidence of muscle and adipose cross-talk and gain new insight into the importance of adipose DICER in the adaptive response of muscle to exercise training
New method to design diamond lattices and other crystals from microscopic building blocks
In a new study appearing in the journal Physical Review Letters, researchers describe a technique for using LEGO®-like elements at the scale of a few billionths of a meter. Further, they are able to cajole these design elements to self-assemble, with each LEGO® piece identifying its proper mate and linking up in a precise sequence to complete the desired nanostructure.
New study explores if flirting is real and shows it can work
A new paper by researchers based at the University of Kansas has been published in the Journal of Sex Research examining if flirting has a particular facial cue effectively used by women to indicate interest in a man.
New study from MD Anderson and BridgeBio's Navire Pharma shows SHP2 inhibition overcomes multiple therapeutic-resistance mechanisms in lung cancer
New preclinical research from MD Anderson and Navire finds a novel drug targeting SHP2 can overcome multiple paths of therapeutic resistance in lung cancer. Navire will launch a clinical trial of SHP2 inhibitors by the end of 2020.
New treatments for deadly lung disease could be revealed by 3D modeling
A 3D bioengineered model of lung tissue built by University of Michigan researchers is poking holes in decades worth of flat, Petri dish observations into how the deadly disease pulmonary fibrosis progresses.
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.
Novel immune-oncology approach for potential cancer treatment
A research collaboration between Monash University and Lava Therapeutics details a novel immune-oncology approach for the potential treatment of cancer.
Older people with early, asymptomatic Alzheimer's at risk of falls
Older people without cognitive problems who experience a fall may have undetected neurodegeneration in their brains that puts them at high risk of developing Alzheimer's dementia, according to a study from Washington University School of Medicine in St. Louis.
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...
Paying GPs to provide contraception information linked to reduced abortions
Providing general practitioners (GPs) with financial incentives to offer information about long-acting contraceptives, such as the hormonal implant, is associated with an increase in their use, and a fall in the number of abortions .
Physicists "trick" photons into behaving like electrons using a "synthetic" magnetic field
Scientists have discovered an elegant way of manipulating light using a "synthetic" Lorentz force -- which in nature is responsible for many fascinating phenomena including the Aurora Borealis.
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...
