By blocking the action of a single protein, scientists have extended the average life span of the mice in their experiment by around 25%. This recent finding has raised the question of whether such a treatment could ever work for people, and so far, there are some promising early hints that it might. In the … Read more
A single, small molecule can restore muscle strength, fuel brain cell growth and reduce inflammation in old mice, new research shows. So far, the anti-aging molecule has only been tested in rodents and in human cells in lab dishes. But the researchers say the results are compelling enough to move the compound toward human trials, … Read more
Proteins found in tiny, indestructible tardigrades could potentially be a key ingredient in slowing the aging process in humans, scientists claim. However, it will take more work to show these proteins are a veritable fountain of youth — for now, the researchers have only early hints from lab-dish experiments.. Also known as water bears, tardigrades … Read more
Scientists reversed some signs of immune aging in mice with a new treatment that could one day potentially be used in humans. The new immunotherapy works by disrupting a natural process by which the immune system becomes biased towards making one type of cell as it ages. The mouse study is an “important” proof-of-concept, but … Read more
Why do common shrews live for only two years, while bowhead whales survive for two centuries? And could the answer give us hints as to how to extend our own, human life spans? The maximum life span of each species is estimated using the age of its longest-living member, and these vary by orders of … Read more
Name: Mexican salamander (Ambystoma mexicanum) also known as an axolotl Where it lives: Lake Xochimilco and Lake Chalco, near Mexico City What it eats: a variety of small invertebrates, along with some small fish Why it’s awesome: Despite its rarity, the axolotl’s incredibly cute looks has made it one of the world’s most famous amphibians, … Read more
Scientists have long debated the greatest possible age of a person, with previous studies placing the limit at up to 150 years. But in the past 25 years, no one has surpassed the record for the world’s oldest person, held by Jean Louise Calment, who died at age 122 in 1997. “This has led people … Read more
