The behavior of therapeutic antibodies in immunotherapy

Since the late 1990s, immunotherapy has been the frontline treatment against lymphomas where synthetic antibodies are used to stop the proliferation of cancerous white blood cells. However, in the more than 20 years since their use began, the molecular mechanisms that underlie this therapy are still little understood. For the first time, scientists from the CNRS, Institut Pasteur and Université...

The larynx has evolved more rapidly in primates

The larynx is larger, more variable in size, and has undergone faster rates of evolution in primates than in carnivores, according to a study published August 11, 2020 in the open-access journal PLOS Biology by Daniel Bowling of Stanford University, W. Tecumseh Fitch of the University of Vienna, and colleagues.

UCalgary researchers discover the microbiome's role in attacking cancerous tumours

University of Calgary researchers have discovered which gut bacteria help our immune system battle cancerous tumours and how they do it. The discovery may provide a new understanding of why immunotherapy, a treatment for cancer that helps amplify immune response, works in some cases, but not others. The findings, published in Science, show combining immunotherapy with specific microbial therapy...

UMD researchers identify structure of blue whirls

'Blue whirls' -- small, spinning blue flames that produce almost no soot when they burn -- have attracted great interest since their discovery in 2016, in part because they represent a potential new avenue for low-emission combustion. Now, a team of researchers has identified how these intriguing whirls are structured.

Unread second-opinion radiology reports waste health care resources

According to ARRS' American Journal of Roentgenology (AJR), 537 of 4,696 second-opinion reports--11.4%, likely underestimated, too--were not read by a clinician. The imaging modality with the highest rate of not being read was sonography (62.5%), the requesting specialty with the highest rate was pediatrics (33.8%), and the radiologic subspecialty with the highest rate was interventional radiology...

Waistline matters in kidney disease

Does fat matter in kidney disease? The investigators found that all measures of higher abdominal fat content (including visceral fat, liver fat, or subcutaneous fat) and slower walk times were associated with increased levels of cardiometabolic risk factors in adults with non-dialysis dependent kidney disease. These data highlight that abdominal fat measures and lower physical fitness levels are...

When you're smiling, the whole world really does smile with you

From Sinatra to Katy Perry, celebrities have long sung about the power of a smile -- how it picks you up, changes your outlook, and generally makes you feel better. But is it all smoke and mirrors, or is there a scientific backing to the claim? Groundbreaking research from the University of South Australia confirms that the act of smiling can trick your mind into being more positive, simply by...

New super-resolution method reveals fine details without constantly needing to zoom in

Since the early 1930s, electron microscopy has provided unprecedented access to the alien world of the extraordinarily small, revealing intricate details that are otherwise impossible to discern with conventional light microscopy. But to achieve high resolution over a large specimen area, the energy of the electron beams needs to be cranked up, which is costly and detrimental to the specimen under...

Coastal flooding study finds trust-building, power-sharing key for environmental justice

It took two years and $11 million, but eventually ranchers, politicians and scientists came to a consensus about how to prevent flooding in Tillamook, a coastal Oregon town. A recent study by Portland State University researchers examining the social factors involved in this decision-making process showcases how environmental justice can be served when affected parties have a seat at the table....
