The combination therapy is Opdivo (nivolumab) and Yervoy (ipilimumab) for the first-line treatment of adults with malignant pleural mesothelioma that cannot be removed by surgery.
Yet a few will have severe reactions and require hospitalization. Just like with flu or any cause of respiratory distress, age is the biggest risk factor, as are preexisting conditions that can aggravate numerous health issues, but research by the COVID-19 Host Genetics Initiative has shown that genetic variants in one region on chromosome 3 impose a larger risk that their carriers will develop a severe form of the disease. Across all ages and strata of health.
The archaeological structures and materials from a funerary ritual tell a tale of human and animal sacrifice, ancestral cults and propitiatory rituals, or they could be divine prayers in commemorative festivities.
The two adult human skulls are an older male and a younger female. The female skull shows a depression in the frontal bone, which probably comes from an incomplete trepanation, as well as cuts in the occipital bone produced by decapitation.
How can it be done safely?
The example of Bombardier Aviation in an analysis published in Canadian Medical Association Journal finds that creating "work bubbles" during the COVID-19 pandemic can help reduce the risk of company-wide outbreaks while helping essential businesses continue to function.
Could it prevent COVID-19, though? A clinical trial of health care workers finds that it does not, though the good news is that because the trial was health care workers they had low rates of infection anyway, likely due to other prevention measures. Masks, hand-washing, and social distancing work.
Yet as we have seen, those are only telling part of the science story. Coronavirus is in the same family as the common cold and for many COVID-19 will be just like the cold, and can spread like the cold. But when it comes to successful transmission, viruses only win they can optimize their aptitude to survive and reproduce in given conditions - which means they lose if we can optimize disease control measures.
Physicists refer to such groups of particles as quasiparticles and while they live, they are useful in helping us understand superconductivity and superfluidity. But many quasiparticles die after less than one second.
What kills them? How do quasiparticles die?
A new paper goes beyond the usual suspect - quasiparticle decay into lower energy states - and identifies a new culprit: many-body dephasing.
In April, the editors of the Oxford English Dictionary did something unusual. For the previous 20 years, they had issued quarterly updates to announce new words and meanings selected for inclusion. These updates have typically been made available in March, June, September and December.
In the late spring, however, and again in July, the dictionary’s editors released special updates, citing a need to document the impact of the COVID-19 pandemic on the English language.
Why are some humans cruel to people who don’t even pose a threat to them – sometimes even their own children? Where does this behaviour come from and what purpose does it serve? Ruth, 45, London.
Humans are the glory and the scum of the universe, concluded the French philosopher, Blaise Pascal, in 1658. Little has changed. We love and we loathe; we help and we harm; we reach out a hand and we stick in the knife.
We understand if someone lashes out in retaliation or self-defence. But when someone harms the harmless, we ask: “How could you?”
