No doubt the ALF will want to make up some Molotov cocktails and start threatening to murder scientists’ children: Biotechnologists have engineered transparent fish to observe how cancer grows and spreads. From the story:
A transparent zebrafish has been engineered to allow scientists to watch how cancers develop and behave inside the body in real time. Each internal organ of the fish and its bones can be seen clearly throughout its life. Observations have shown already that the spread of cancer cells is not random—they home in on a particular area.I’m sure Ingrid Newkirk is rending her garments: Oh, the cruelty to a sentient being! Oh, the evil! Oh, the tremendous good that can come from this for the alleviation of terrible human suffering.
Researchers who bred the transparent fish at the Children’s Hospital, Boston, in the United States, were able to watch as melanoma cells left the abdominal cavity and made directly for the skin, where the disease took hold. Before the innovation, scientists were reliant on getting a snapshot of the spread by dissecting specimens.
Richard White, the lead researcher in the project, reported in the journal Cell Stem Cell, said that cancer changed so rapidly in the body that dissection was “bound to miss something”, but the transparent fish allowed the whole process to be witnessed.
You have a decision to make: double or nothing.
For this week only, a generous supporter has offered to fully match all new and increased donations to First Things up to $60,000.
In other words, your gift of $50 unlocks $100 for First Things, your gift of $100 unlocks $200, and so on, up to a total of $120,000. But if you don’t give, nothing.
So what will it be, dear reader: double, or nothing?
Make your year-end gift go twice as far for First Things by giving now.
