A ‘longevity protein’ discovered in the DNA of centenarians promises to rejuvenate the heart by at least 10 years. Hope comes from a preclinical study coordinated by Annibale Puca of the MultiMedica group in Milan and Paolo Madeddu of the University of Bristol in the United Kingdom, funded by the British Heart Foundation and the Italian Ministry of Health and published in ‘Cardiovascular Research’, a journal of the European Society of Cardiology (ESC).

In this Review, Villeda and colleagues describe blood-to-brain communication from a systems physiology perspective, with an emphasis on blood-derived signals as potent drivers of both age-related brain dysfunction and brain rejuvenation.
Every pet owner knows the heartbreaking reality: Companion animals’ lives are shorter than ours.
Now, a San Francisco biotech startup is working on drugs to help dogs live longer, healthier lives.
“We want to give people more time with the pets they love,” said Celine Halioua, 28, a scientist who founded Loyal in 2019 with no more than an idea. She’s now CEO of a 58-person company backed by $60 million in venture capital. “Everyone has stories about beloved pets gone too soon.”
But doubts remain about whether cell reprogramming technique could one day help humans.
Researchers look at DNA of lab mice and ultimately reverse ageing process Related: Empowered Aging Scientists have made a new discovery about how to reverse the ageing process through looking at the way in which cells in DNA are organised. In a new study published in Cell, David Sinclair, who is a professor of genetics at Harvard Medical School, and his team described how they looked at a genome, which is called epigenome, in mice to study the ageing process.
Summary: Study uncovers new genetic risk factors for age-related macular degeneration, a leading cause of vision loss in adults.
