Computer model developed for predicting the dispersion of vog
A paper published this month in the Bulletin of the American Meteorological Society details the development and utility of a computer model for the dispersion of volcanic smog or 'vog,' which forms when volcanic sulfur dioxide gas interacts with water and coverts it to acid sulfate aerosol particles in the atmosphere.
Strangled cells condense their DNA
Scientists at the Institute of Molecular Biology have been able to see, for the first time, the dramatic changes that occur in the DNA of cells that are starved of oxygen and nutrients.
Environmental factors may contribute to the development of some childhood cancers
Environmental factors may be a contributory cause in the development of some childhood cancers, leading scientists have revealed.
How low to go for blood pressure? Lower target could affect millions of Americans
At least 16.8 million Americans could benefit from lowering their systolic blood pressure to 120 mmHg, much lower than current guidelines, according to a University of Utah led study to be published in the Journal of the American College of Cardiology on Nov.
CPR by medics: Keep pumping or stop for rescue breathing?
The largest study so far of the outcomes of CPR performed by medics for people suffering an out-of-hospital cardiac arrest was conducted at 114 agencies across the United States and Canada.
TSRI-led team finds long-sought protein sensor for the 'sixth sense' -- proprioception
For decades, biologists have been trying to find the crucial sensor protein in nerve endings that translates muscle and tendon stretching into proprioceptive nerve signals.
Could solar eclipses disrupt electricity in Germany?
Could a solar eclipse over Europe during the day affect the power generated by Germany's photovoltaic systems or solar panels, thereby challenging the reliability of the electrical supply across the country?
Study shows benefits of intensive blood pressure management
Patients whose blood pressure target was lowered to a systolic goal of less than 120 mmHg had their risk for heart attack, heart failure or stroke reduced by 24 percent, and risk for death lowered by 27 percent, but was accompanied by increased risk for adverse events such as kidney abnormalities.
Common medication for heart failure patients does not increase activity level
Heart failure patients with preserved ejection fraction -- where the heart becomes stiff and cannot relax or fill properly -- did not have increased exercise tolerance after taking isosorbide mononitrate, compared to a placebo.
Wealthiest -- not sickest -- patients may have edge in organ transplants
Registering at multiple transplant centers appears to give an edge to wealthy organ transplant patients over those with the most medical need.

Increasing production of seed oils
Researchers in Japan have succeeded in inducing the genes involved in oil synthesis in seeds to work for longer periods of time, thereby allowing them to accumulate more seed oil.
Mayo Clinic study: One energy drink may increase heart disease risk in young adults

#568 Poker Face Psychology
Anyone who's seen pop culture depictions of poker might think statistics and math is the only way to get ahead. But no, there's psychology too. Author Maria Konnikova took her Ph.D. in psychology to the poker table, and turned out to be good. So good, she went pro in poker, and learned all about her own biases on the way. We're talking about her new book "The Biggest Bluff: How I Learned to Pay Attention, Master Myself, and Win".

Invisible Allies
As scientists have been scrambling to find new and better ways to treat covid-19, they've come across some unexpected allies. Invisible and primordial, these protectors have been with us all along. And they just might help us to better weather this viral storm. To kick things off, we travel through time from a homeless shelter to a military hospital, pondering the pandemic-fighting power of the sun. And then, we dive deep into the periodic table to look at how a simple element might actually be a microbe's biggest foe. This episode was reported by Simon Adler and Molly Webster, and produced by Annie McEwen and Pat Walters. Support Radiolab today at Radiolab.org/donate.
