Đậu Hà Lan, vi khuẩn và DNA: Hành trình trăm năm tìm ra bản chất di truyền. Từ thí nghiệm của Mendel đến phát hiện DNA là vật chất di truyền, loài người đã vén bức màn bí ẩn về gen. Hershey-Chase xác nhận DNA, không phải protein, mang thông tin di truyền. Câu chuyện không kết thúc – nó mở ra sinh học hiện đại.

"All told, more than half of Parkinson’s research dollars in the past two decades have flowed toward genetics.
But Parkinson’s rates in the US have doubled in the past 30 years. And studies suggest they will climb another 15 to 35 percent in each coming decade. This is not how an inherited genetic disease is supposed to behave.
Despite the avalanche of funding, the latest research suggests that only 10 to 15 percent of Parkinson’s cases can be fully explained by genetics. The other three-quarters are, functionally, a mystery. “More than two-thirds of people with PD don’t have any clear genetic link,” says Briana De Miranda, a researcher at the University of Alabama at Birmingham. “So, we’re moving to a new question: What else could it be?”
“The health you enjoy or don’t enjoy today is a function of your environment in the past,” says Ray Dorsey, a physician and professor of neurology at the University of Rochester. Your “environment” could be the refinery a town over, the lead in the paint of your mother’s home, the plastic sheath of the Hot Pocket you microwaved in 1996. It is air pollution and PFAS and pesticides and so much more.
And this environment of yours—the sum of all your exposures, from conception to the grave—could be making you sicker than you realize. In a study of half a million Britons, Oxford researchers determined that lifestyle and the environment is 10 times more likely to explain early death than genetics. But that also offers a tantalizing prospect. If Parkinson’s is an environmental disease, as Dorsey and a small band of researchers emphatically believe, then maybe we can end it."

🇮🇹 **Archaeogenetics reconstructs demography and extreme parental consanguinity in a Bronze Age community from Southern Italy**
"_The community shows closer genetic affinity to Early Bronze Age Sicilians than to contemporaneous populations from the Italian peninsula. However, unlike contemporary Sicilian individuals, they lack eastern genetic influences, suggesting distinct ancestral trajectories and interaction networks among Bronze Age populations._"

"The rise of the eukaryotes was one of the most important events in Earth’s history. If it had not occurred, there would be no great white sharks, no towering redwood trees, no hovering hummingbirds and no people. Just slimy layers of bacteria and archaea, everywhere. And the Asgard archaea may have started it all."

Oncological diseases are characterized by rapid development of cells
Oncological diseases are a whole category of diseases (often identified as cancer) characterized by chaotic, uncontrolled and rapid development of cells. As a rule, the full name of the cancer is supplemented by the name of the affected organ (for example: pancreatic cancer, lung cancer, liver cancer).

"We’re all more closely related than we know, and our family has been murdering its own.
I’d think a realization like that should send every nationalist running for the shelter of cosmopolitan liberalism. Here we will treat you as a man and a brother, no matter who you are, and nowhere else can promise that. Let’s build a polity that’s faithful to the memory of all of our ancestors."
P.S. I don't know why Kuznicki uses male-gendered terms here.
