Laboratory-grown red blood cells have been transfused into people in the first such clinical trial in the world, the United Kingdoms National Health Service announced on Sunday.  According to the University of Bristol, which worked on the RESTORE research initiative jointly with the NHS and the University of Cambridge, two people have been given the […]

For the first time in the world and only at Tel Aviv Sourasky Medical Center, pathologists have found a way to diagnose a cancer mutation and adjust treatment within minutes through a unique Israeli development that combines digital pathology with artificial intelligence.  A complex genetic molecular test must be performed on each tumor to locate […]

In modern English, we often use the terms vows and oaths interchangeably. But as we’ve seen already in this tractate, these are two very different things.  On today’s daf, we find a new distinction between oaths and vows. The Gemara tells us that in some ways, vows are more stringent than oaths and in other ways, oaths are more […]

It is hard to get one’s head around that question. But no less challenging is the language of the book. The grammar and vocabulary go far […]

In a mishnah at the bottom of yesterday’s daf, we learn a fairly straightforward rule: A person may not say to a butcher on a festival: Weigh for me a dinar’s worth of meat. But the butcher may slaughter an animal and apportion it without stipulating a price. As has been well established by our […]
