神奇！2017关于人类身体的11项重大科学发现

4. We were wrong - the testes are connected to the immune system after all. Researchers have discovered a "very small door" that allows the testes to send one-way signals to the immune system, and it could explain why some men struggle with infertility, and why certain cancer vaccines keep failing.

我们错了——最终睾丸还是与免疫系统有关联的。研究人员发现了“一扇非常小的门”使睾丸可以向免疫系统发送单向信号，这解释了为什么一些男性会被不孕症所困扰，也解释了某些癌症疫苗一直失败的原因。

5. The causes of hair loss and greying are linked, and for the first time, scientists have identified the cells responsible.

脱发和头发变白的原因是相关的，科学家首次确认了对此负有责任的细胞。

6. A brand new human organ has been classified. Researchers have given the nod to the mesentery - an organ that's been hiding in plain sight in our digestive system this whole time. But that's only half the story, because we're still not sure exactly what it does.

一种全新的器官被归类了。研究人员同意为肠系膜归类，这种器官显然一直隐藏在我们的消化系统中。但这只是其中的一方面，因为我们还不确定它到底是什么。

7. An unexpected new lung function has been found. Researchers have found that lungs don't just facilitate respiration - they also play a key role in blood production, with the ability to produce more than 10 million platelets (tiny blood cells) per hour. That equates to the majority of platelets in circulation at any given moment.
