The American Medical Association has joined the African American Tobacco Control Leadership Council in suing the Food and Drug Administration on their inaction to ban menthol-flavored tobacco products which have been heavily marketed by cigarette companies to Black communities for decades.
In a groundbreaking new study, researchers at the University of Minnesota, in collaboration with the U.S. Army Combat Capabilities Development Command Soldier Center, have 3D printed unique fluid channels at the micron scale that could automate production of diagnostics, sensors, and assays used for a variety of medical tests and other applications.
Volume 11, Issue 28 of Oncotarget features "Development and comprehensive characterization of porcine hepatocellular carcinoma for translational liver cancer investigation" by Gaba et, al. which reported that reliable development of Oncopig HCC cell lines was demonstrated through hepatocyte isolation and Cre recombinase exposure across 15 Oncopigs.
Parity-time-symmetric photonic and optoelectronic systems is being intensively explored recently, which has been bringing about significant fundamental physics and technological outcomes. One of the main characteristics of a PT symmetric system is its effectiveness in mode selection in a single-mode lasing, in which two cross-coupled and spatially separated resonators with identical geometries are usually employed. A PT-symmetric laser system has a strongly enhanced gain difference between the dominant mode and the side modes, thus making single-mode oscillation possible.
CAMBRIDGE, MA - October 8 2020--The preprints selected for review in Rapid Reviews: COVID-19 (RR:C19), an open-access overlay journal published by the MIT Press, cover a wide range of subjects, with peer reviewers finding a study that higher levels of cytokines IL-6 and IL-10 are associated with increased severity of COVID-19 is particularly noteworthy and could be useful in clinical care.
A research collaboration between Queen Mary University of London, the University of Cambridge and the Institute for High Pressure Physics in Troitsk has discovered the fastest possible speed of sound.
The result- about 36 km per second - is around twice as fast as the speed of sound in diamond, the hardest known material in the world.
Seismic waves, commonly associated with earthquakes, have been used by scientists to develop a universal scaling law for the sense of touch. A team, led by researchers at the University of Birmingham, used Rayleigh waves to create the first scaling law for touch sensitivity. The results are published in Science Advances.
The researchers are part of a European consortium (H-Reality) that are already using the theory to develop new Virtual Reality technologies that incorporate the sense of touch.
By applying natural language processing tools to the movements of protein molecules, University of Maryland scientists created an abstract language that describes the multiple shapes a protein molecule can take and how and when it transitions from one shape to another.
Bottom Line: Analysis of DNA copy number variants (CNVs) in the cells exfoliated in urine showed better sensitivity and similar specificity in detecting urothelial carcinoma compared with urine cytology.

The COVID-19 pandemic provides an opportunity to reset the global economy and reverse decades of ecosystem and species losses, but most countries are failing to invest in nature-related economic reforms or investments, according to a Rutgers-led paper.
Could something as simple as a certain type of sugar water be medicine for perforated bones, and even bone marrow cancer itself?
Inside our bodies are some jellyfish-like cells that actually eat away at our bones. Every year, they eat about ten per cent of the bone mass in our body. Fortunately, other cells usually follow and build up new bone.
We undergo a kind of continuous remodelling and repair that enables most of us to traipse around with steel in our legs and arms.
Leesburg, VA, October 9, 2020--According to an article in ARRS' American Journal of Roentgenology (AJR), the imaging findings of in situ pulmonary artery thrombosis (PAT) associated with radiation therapy (RT) are different from those of acute pulmonary emboli and do not appear to embolize. Due to the differences in clinical prognosis and subsequent management strategies, in situ PAT associated with RT--"which to our knowledge has not previously been described in the English literature," wrote the authors of this AJR article--must be distinguished from pulmonary embolism.
A team of chemists from RUDN University suggested a new reaction to produce organic compounds in one vessel. The end products turned out to be effective against the cells of carcinomas, including drug-resistant ones. The new reaction was described in the Bioorganic Chemistry journal.
Banyan trees are fig trees that begin their life as an epiphyte. The most noticeable feature of banyan Ficus species is their extraordinary aerial roots, which enable them to live as hemi-epiphytes, as do the strangler figs often seen in tropical forests.
As of October 2020, SARS-CoV-2 causes an ongoing pandemic, with more than 35 million reported cases and more than 1 million deaths worldwide. One prominent feature that distinguishes COVID-19 from SARS in terms of immune responses is the poor induction of a type I interferon (IFN) response by SARS-CoV-2 compared to SARS-CoV and influenza A virus. Notably, impaired IFN responses are associated with COVID-19 disease. However, the molecular mechanisms underlying the inefficient IFN responses in SARS-CoV-2 infection remain unclear.
