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