每日英語跟讀 Ep.K345: About Science - Ants have the ability to sniff out cancer in humans, study reveals

Ants have the ability to sniff out cancerous cells in humans, a new study has discovered, suggesting they could be used for cancer diagnosis in future.

一項新研究發現,螞蟻能嗅出人體內的癌細胞,這表明螞蟻可用於未來對癌症的診斷。

Researchers from the French National Centre for Scientific Research (CNRS) discovered that ant species Formica fusca has a well developed sense of smell.

法國國家科學研究中心(CNRS)的研究人員發現,「黑山蟻」(學名:Formica fusca )這種螞蟻品種,嗅覺非常發達。

It was able to differentiate cancerous cells from healthy cells in humans, thanks to their sense of smell, limited trials revealed. But more clinical tests must be carried out before they could be used in clinical settings like hospitals, the team said.

有限的實驗顯示,這種螞蟻的嗅覺超強,能夠將人體的癌細胞與健康細胞區分開來。但是該研究團隊表示,還需要進行更多臨床測試,才能將黑山蟻用於醫院等臨床環境中。

They suggest that in future, ants could turn out to be better at dogs when it comes to locating cancerous cells in humans.

他們人員指出,未來在識別人體癌細胞方面,螞蟻可能會比狗做得更出色。

科學家使用細胞再生技術讓老鼠回春 Scientists Reverse Aging In Mice Using Cell Rejuvenation Technique

Researchers in the US treated healthy mice with a form of gene therapy that refreshed older cells, making the animals more youthful according to biological markers that are used to measure the effects of ageing.

美國研究人員對健康老鼠實施一種更新老化細胞的基因療法,他們透過用來衡量老化效應的生物標記法,測出這些老鼠變年輕了。

Repeating the trick in humans is far from straightforward, but the findings will fuel interest in radical new therapies that aim to slow or reverse the ageing process as a means of tackling age-related diseases such as cancer, brittle bones and Alzheimer’s.

儘管難以用同樣的方法讓人類返老還童,但這一發現將點燃人們對以延緩或逆轉衰老為目標的激進新療法的興趣,這種療法可以用來治療諸如癌症、骨質疏鬆和阿茲海默症等與年齡相關的疾病。

The scientists drew on previous work by the Japanese Nobel laureate Prof Shinya Yamanaka, who showed that a mixture of four molecules – known as Yamanaka factors – can rewind adult cells into youthful stem cells that are capable of forming almost any tissue in the body.

科學家這一療法借鑑日本諾貝爾獎得主山中伸彌教授先前的研究成果。山中伸彌向世人展示,被稱為「山中因子」的4種分子組合在一起,可以讓成人細胞逆生長為年輕的幹細胞,而幹細胞可以分化成人體的任何組織。Source article: https://features.ltn.com.tw/english/article/paper/1506995 ; https://features.ltn.com.tw/english/article/paper/1508339
