A new report out Wednesday says some popular fruit juices may contain heavy metal contaminants like lead, arsenic, and cadmium. Consumer Reports tested 45 packaged fruit juices and found measurable levels of heavy metal in every product. Long-term exposure to these metals could cause serious health risks, including kidney disease and certain types of cancer. Anna Werner reports.
David Sinclair is a Professor in the Department of Genetics at Harvard Medical School and co-Director of the Paul Glenn Centre for the Biological Mechanisms of Ageing.
Today we hear from a scientist at the cutting edge of longevity research as Professor Sinclair gives us a fascinating insight into the world of anti-ageing.
Expect to learn how and why we age, why stabilising the epigenetic landscape may enable a human to live for 1000 years, exactly what tactics Professor Sinclair is using himself to try and extend his life and how fasting, Sirtuins and NAD can be used to promote health and reduce diseases.

The lionfish is an invasive species that is currently wreaking havoc in the warm waters of the Bahamas, the Caribbean, and the US southwestern Atlantic and Gulf of Mexico coasts. But where did they come from and what makes this normally docile hunter suddenly turn vicious in its new home? To answer these questions, North Carolina State University initiated a study of lionfish genetics to learn more about their origins and how to control them.
Researchers at the XENON dark matter observatory have spotted something incredibly rare. Unfortunately, it’s not dark matter, but it is the next best thing. The detectors at the observatory have spotted the decay of xenon-124, the rarest event ever recorded in human history.
The XENON experiment is designed to detect dark matter, which is not an easy task. The reason that dark matter is so mysterious is that it pretty much never does anything, which makes it hard to spot. Dark matter doesn’t give off light, or have any sort of magnetic field, and it almost never interacts with normal matter in any way.
For some time now, we’ve seen robotic surgical devices that can be remotely guided within the human body. And while they do make surgery more precise and less invasive, they still have to be continuously operated by a surgeon. Recently, however, a robotic catheter successfully navigated beating pig hearts on its own.
An army of tiny robots scuttling about inside your mouth cleaning your teeth. It’s a disquieting thought, and yet it might be one of the most effective ways to deal with the sticky bacterial biofilms that coat our choppers – as well as water pipes, catheters and other tough-to-clean items.
Anyone who’s been laid up for an extended period due to illness or injury will know how difficult it can be to get moving again. Long-term immobility can see a loss of muscle mass that can be hard to regain, especially for the elderly. In research on mice, a team at the University of Illinois at Urbana-Champaign have found that the injection of a type of cells known to promote blood vessel growth helps accelerate to restoration of muscle mass lost due to inactivity.
