Strict diet suspends development, doubles lifespan of worms

  The centuries-long search for the fountain of youth has yielded only a few promising leads, one of which entails an extreme, emaciating diet. A new study of the tiny nematode worm C. elegans begins to explain this marvel of calorie restriction and hints at an easier way to achieve longevity. Researchers at Duke University found that…

Salamanders Give Clues to How We Might Regrow Human Limbs

  Humans have some regenerative abilities but compared to creatures like the salamander, which has an amazing ability to regenerate after injury, we’re pretty limited. Not only are salamanders the only adult vertebrates able to regrow full limbs, they’re able to regenerate an impressive repertoire of complex structures including parts of their hearts, eyes, spinal cord and…

Century-old drug reverses signs of autism in mice

A single dose of a century-old drug has eliminated autism symptoms in adult mice with an experimental form of the disorder. Originally developed to treat African sleeping sickness, the compound, called suramin, quells a heightened stress response in neurons that researchers believe may underlie some traits of autism. The finding raises the hope that some…

Gene ‘switch’ reverses cancer in common childhood leukemia

Melbourne researchers have shown a type of leukemia can be successfully 'reversed' by coaxing the cancer cells back into normal development. The discovery was made using a model of B-progenitor acute lymphoblastic leukemia (B-ALL), the most common cancer affecting children. Researchers from the Walter and Eliza Hall Institute showed that switching off a gene called Pax5 could…

Anti-diabetic drug slows aging and lengthens lifespan, animal study suggests

A study by Belgian doctoral researcher Wouter De Haes (KU Leuven) and colleagues provides new evidence that metformin, the world's most widely used anti-diabetic drug, slows aging and increases lifespan. In experiments reported in the journal Proceedings of the National Academy of Sciences, the researchers tease out the mechanism behind metformin's age-slowing effects: the drug causes…

A habitable environment on Martian volcano?

The  Martian volcano Arsia Mons may have been home to one of the most recent habitable environments yet found on the Red Planet, geologists say. The research shows that volcanic eruptions beneath a glacial ice sheet would have created substantial amounts of liquid water on Mars's surface around 210 million years ago. Where there was water,…

Woman’s cancer wiped out … by measles virus

In a breakthrough that could offer new hope to people with some kinds of cancer, Mayo Clinic researchers say they managed to wipe out a woman's cancer with a blast of measles vaccine strong enough to inoculate 10 million people. The 50-year-old woman's blood cancer, which had spread through her body, went into complete remission…
