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.
To understand the machinery of life, this scientist breaks it on purpose
By tinkering with some of life's oldest components, astrobiologists hope to find clues about how life emerged. In a recent paper, a group led by Betül Kaçar at the University of Arizona report an unexpected discovery, hinting at an effect that prevents organisms from ever reaching evolutionary perfection.
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...
UChicago scientists discover way to make quantum states last 10,000 times longer
A team of scientists at the University of Chicago's Pritzker School of Molecular Engineering announced the discovery of a simple modification that allows quantum systems to stay operational--or 'coherent'--10,000 times longer than before.
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...
USC scientists identify the order of COVID-19's symptoms
COVID-19 has some symptoms in the upper and lower gastrointestinal tracts that may help doctors rule out flu or other illnesses and hasten treatment.
Virus uses decoy strategy to evade immune system, Otago research reveals
University of Otago researchers have learnt more about how viruses operate and can evade the immune system and are now using their discovery to help learn more about COVID-19.
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...
Warming Greenland ice sheet passes point of no return
Nearly 40 years of satellite data from Greenland shows that glaciers on the island have shrunk so much that even if global warming were to stop today, the ice sheet would continue shrinking.
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...
Who's your daddy? Male seahorses transport nutrients to embryos
New research by Dr Camilla Whittington and her team at the University of Sydney has found male seahorses transport nutrients to their developing babies during pregnancy. This discovery provides an opportunity for further comparative evolutionary research.
WTF, when will scientists learn to use fewer acronyms?
Have you heard of DNA? It stands for Do Not Abbreviate apparently. Jokes aside, it's the most widely used acronym in scientific literature in the past 70 years, appearing more than 2.4 million times.

Neuroscientists have discovered that the degree of motivation and the stamina to keep it up depends on the ratio between the neurotransmitters glutamine and glutamate in the nucleus accumbens of the brain.
New super-resolution method reveals fine details without constantly needing to zoom in
- ScienceDaily
- 20/8/13 02:13
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....
