A team of researchers at Memorial Sloan Kettering Cancer Center (MSK) reported on the epidemiology of COVID-19 illness experienced at an NCI-designated cancer center during the height of pandemic in New York City.

The characterization of COVID-19 in patients with cancer remains limited in published studies and nationwide surveillance analyses. Reports from China and Italy have raised the possibility that patients with cancer on active therapy have a higher risk of COVID-19 related severe events, although there is a knowledge gap as to which aspects of cancer and its treatment increase the risk of severe COVID-19 disease.

According to a new study from Memorial Sloan Kettering published June 24 in Nature Medicine, patients in active cancer treatment who develop COVID-19 infection don’t fare any worse than other hospitalized patients. Notably, metastatic disease, recent chemotherapy, or major surgery within the previous 30 days did not show a significant association with either hospitalization or severe respiratory illness due to COVID-19. Researchers say their findings suggest that no one should delay cancer treatment because of concerns about the virus.

Aliens & Black Holes

Penrose predicted that the object would acquire a negative energy in this unusual area of space. By dropping the object and splitting it in two so that one half falls into the black hole while the other is recovered, the recoil action would measure a loss of negative energy—effectively, the recovered half would gain energy extracted from the black hole’s rotation. The scale of the engineering challenge the process would require is so great, however, that Penrose suggested only a very advanced, perhaps alien, civilisation would be equal to the task.

SpaceX pushed a massive tank for its latest Starship prototype beyond its limits Tuesday (June 23) in an intentionally explosive test in South Texas.

The Starship SN7 prototype tank ruptured during a pressure test at SpaceX’s Boca Chica proving grounds, the second in just over a week for the spacecraft component. But where a June 15 test resulted in a leak, Tuesday’s test was a bit more dramatic.

It is one of the most astonishing results of physics: when a complex system is left alone, it will return to its initial state with almost perfect precision. Gas particles, for example, chaotically swirling around in a container, will return almost exactly to their starting positions after some time. This “Poincaré Recurrence Theorem” is the foundation of modern chaos theory. For decades, scientists have investigated how this theorem can be applied to the world of quantum physics. Now, researchers at TU Wien (Vienna) have successfully demonstrated a kind of “Poincaré recurrence” in a multi-particle quantum system. The results have been published in the journal Science.

An Old Question, Revisited

At the end of the 19th century, the French scientist Henri Poincaré studied systems which cannot be fully analysed with perfect precision — for example solar systems consisting of many planets and asteroids, or gas particles, which keep bumping into each other. His surprising result: every state which is physically possible will be occupied by the system at some point — at least to a very good degree of approximation. If we just wait long enough, at some point all planets will form a straight line, just by coincidence. The gas particles in a box will create interesting patterns, or go back to the state in which they were when the experiment started.

Xiang-Dong Fu, PhD, has never been more excited about something in his entire career. He has long studied the basic biology of RNA, a genetic cousin of DNA, and the proteins that bind it. But a single discovery has launched Fu into a completely new field: neuroscience.

For decades, Fu and his team at University of California San Diego School of Medicine studied a protein called PTB, which is well known for binding RNA and influencing which genes are turned “on” or “off” in a cell. To study the role of a protein like PTB, scientists often manipulate cells to reduce the amount of that protein, and then watch to see what happens.

But then he noticed something odd after a couple of weeks — there were very few fibroblasts left. Almost the whole dish was instead filled with neurons.

NASA still hasn’t decided whether Dragon will land in the Atlantic or Gulf of Mexico.

Axions? Phantom energy? Astrophysicists scramble to patch a hole in the universe, rewriting cosmic history in the process.

As of December 4, 2019, 565 people from 41 countries have gone into space. That’s it. 565 out of more than 7 billion of us currently on this planet. And that’s using the definition of space travel to include any flight over 62 miles or about 100 kilometers.

Many of these space travelers are, of course, NASA astronauts. That means they went through a rigorous application and training process. So, what exactly does it take to be an astronaut?

To be considered for the NASA astronaut program is you must be a U.S. citizen. Dual citizenship is okay.
