面对失去宠物的痛苦，宠物主人如今有了越来越多的生物技术选择。这些选择从延寿药物到克隆和冷冻保存不等。
Pet owners who cannot face losing an animal now have a growing menu of biotech options. They range from longevity drugs to cloning and cryonics.
MIT Technology Review 本周梳理了这些选项，并质疑其中一些是否明智。
MIT Technology Review laid out the options this week, and questioned whether some of them are wise.
针对老年犬的药物 美国初创公司 Loyal 正在研发三种药物，旨在帮助狗延长寿命。其中一种 LOY-002 是供老年犬每日服用的药片，目前正在美国约 1300 只宠物犬身上进行测试。
Pills for older dogs US startup Loyal is developing three drugs aimed at helping dogs live longer. One, LOY-002, is a daily pill for senior dogs being tested in about 1,300 pet dogs across the US.
今年 1 月，美国监管机构接受了 Loyal 关于该药物的安全数据。这只是获批的一步，而非获批本身。Loyal 预计将在 2027 年申请有条件批准。
In January, US regulators accepted Loyal’s safety data for the drug. That is a step towards approval, not approval itself. Loyal expects to apply for conditional approval in 2027.
其他公司正在测试用于犬只年龄相关问题的药物，如肥胖和关节炎。还有一家公司正在研发猫的延寿药物。
Other companies are testing dog drugs for age-related problems such as obesity and arthritis. One is working on longevity medicines for cats.
5万美元的双胞胎 克隆技术会提取宠物的 DNA，并将其置于同种动物的卵子中。随后，胚胎由代孕动物孕育。
A $50,000 twin Cloning takes a pet’s DNA and places it in an egg from another animal of the same species. The embryo is then carried by a surrogate.
总部位于德克萨斯州的 Viagen Pets 向《MIT Technology Review》透露，为猫或狗进行克隆收费 5 万美元。所得结果是基因双胞胎，而非性格完全相同的复制个体。
Texas-based Viagen Pets charges $50,000 to clone a cat or dog, the magazine reported. The result is a genetic twin, not a copy with the same personality.
科罗拉多州立大学教授 Lori Kogan 研究人与动物之间的纽带。她表示，主人常常面临社会不予承认的悲痛。如果克隆能带来安慰，她质疑道：“我们有什么资格评判？”
Lori Kogan, a Colorado State University professor who studies people’s bonds with animals, said owners often face grief that society does not recognise. If cloning brings them peace, she asked, “who are we to judge?”
为未来而冷冻 一些公司冷冻已故宠物，寄望于未来科学能够让它们复活。位于亚利桑那州的 Alcor 已储存数百只宠物和人类，最近还冷冻了它的第一只宠物糖袋鼠。
Frozen for the future A few companies freeze dead pets in the hope that future science can revive them. Alcor, in Arizona, stores hundreds of pets and people, and recently froze its first pet sugar glider.
专家表示，复活的可能性极低。杂志记者 Jessica Hamzelou 表示，她担心克隆和冷冻保存可能会让孩子认为死亡不是终点。
Experts say revival is highly unlikely. The magazine’s Jessica Hamzelou said she worried both cloning and cryonics could teach children that death is not final.
生物技术抗衰老的推动不仅限于宠物。诸如 HexemBio 之类的初创公司正在为人类的年轻化疗法筹集资金。
Biotech’s push against ageing is not limited to pets. Startups such as HexemBio are raising money for rejuvenation therapies in humans.
