病人的隐私

Betsy Ladyzhets在《作为科学家的病人》(SN: 3/23/24,第22页)中报道,慢性病患者正在自己进行医学研究。

康纳(Connor)是这篇报道中重点提到的一位病人,他要求只透露自己的名字。但故事中写了他配偶的全名。“这究竟如何维护康纳的医疗隐私?”读者汤姆·贝吉奇问道。

Ladyzhets说,康纳的配偶妮可·布鲁诺(Nicole Bruno)同意印上她的姓,因为她的姓和康纳的不一样。作为《科学新闻》事实核查过程的一部分,Ladyzhets在发表之前还与这对夫妇确认了其他细节。

Actually apex?

Shark bites are quite rare, Brianna Randall reported in “Sharks bit fewer than 100 people in 2023” (SN: 3/23/24, p. 4).

Randall wrote that sharks are the ocean’s apex predators, animals at the top of a food web, whose population isn’t regulated by other predators. Reader Bruce Bailey wondered if that’s true, given that orcas sometimes prey on great whites.

Many sharks rank in the middle of a food web, but most sharks that bite humans, including great whites, are apex predators, says population geneticist Gavin Naylor of the Florida Museum of Natural History in Gainesville. And while orcas can kill or temporarily displace a great white, the whales don’t control the sharks’ population, says shark biologist Neil Hammerschlag of Atlantic Shark Expeditions in Boutiliers Point, Canada.
