Seeing a doctor can be crucial to managing and preventing chronic disease but there has long been a racial gap in routine visits that can't be explained by racism or income. 

Maybe people didn't like like going to the doctor because the COVID-19 pandemic caused use of telemedicine to rise sharply, and as that happened gaps in visits disappeared for black patients at Penn Medicine. 

Once “normal” in-office appointments returned, previous inequities stayed erased, indicating that telemedicine wasn’t just a stopgap solution but a potential long-term tool for equity. 

Astronomers have been assuming that real new knowledge of black holes might have to wait until 2030, when/if NASA’s gravitational wave detector, LISA, launches into space.

The Event Horizon Telescope may have something else in mind. They have called a press conference for Thursday and speculation is rampant about what it might mean.

By looking at the ‘shadows’ of two supermassive black holes in the process of colliding, astronomers may have a way to measure black holes in distant galaxies and test competing theories of gravity.

Three years ago, the first ever image of a black hole, at the center of galaxy Messier 87, came into focus thanks to the Event Horizon Telescope, a global network of synchronized radio dishes acting as one giant telescope.

Now a new imaging technique could allow astronomers to study black holes smaller than M87’s, a monster with a mass of 6.5 billion suns, harbored in galaxies more distant than M87, which at 55 million light-years away, is still relatively close to our own Milky Way.

In 2001, after the US World Trade Centers were destroyed in a terrorist attack, assaults on middle-eastern buildings and people in San Francisco went up. Yet the middle eastern people attacked were Jewish, not Muslim. A common sentiment among intelligentsia was that the attacks were due to Israel being created by the United Nations in 1948.

Anti-Semitism has gotten worse rather than better since, despite governments creating laws against hate crimes, according to the 28th Annual Report on Antisemitism Worldwide.

The Uralic language family and languages such as Finnish, Estonian, Saami and Hungarian began to spread west approximately 4,200–3,900 years ago, first to the central Volga region and later to the Baltic Sea and North Atlantic.

The Uralic language family is a few hundred years younger than the Indo-European one, and its spread led to contacts with Indo-Iranian language variants and the creation of a long contact zone in the area currently known as central Russia. Early loan words originating from this contact made their way into the Uralic languages that were beginning to emerge, including Sami, the Balto-Finnic languages, Mordvinic, Mari and the Permic languages.(1) 

There are three dimensions in the known universe. Fiction authors like to call time a dimension but it really isn't, it is just a way to look at the other three. Even if you don't remember what you ate for lunch yesterday the universe knows you were 2 millions miles away from where you are right now when you at it. Since everything in the universe was also shifting in chaotic ways there is no way to return and have a different lunch.
