When a cell senses the damage, one of the substances it produces is a protein called c-GAS. That plays several roles, but what was of interest to these scientists is that in humans, it interferes with and hampers the process by which DNA is knitted back together.
Scientists think that this interference could promote cancer and shorten our lifespan.
In naked mole rats though, the researchers found that the exact same protein does the opposite. It helps the body mend strands of DNA and keeps the genetic code in each cell intact.
They don’t know why or how yet for the mole rat using the same pathway in a different way.
Their percent margin might drop, but there is no way they just eat say a 100 dollar extra tariff charge. They would charge 100 dollars more on the item(s). They make the same profit, consumer pays more. The only time this isn’t true, is if the consumer will not or cannot pay the extra 100 dollars for the product and the sale is lost. In such a case they may try to pay part of the tariff and not raise their costs to account for margin.
In practice I think many companies will actually charge more than the tariff to maintain percent margin.
So definitely affects US consumers and companies, but may not affect foreign companies really at all.
