Ep#04 Aubrey De Grey : What if we don’t have to die

This is a new channel with Liz Parrish. This is an hour with Aubrey.

Most people consider #aging to be a normal part of the cycle of #life and #death. But, did you know that some people see aging merely as a disease?
Which means that they believe there is a cure for aging.
And, these people are in pursuit of that cure.

So, who are these people?
Buyingtime introduces you to Dr Aubrey de Grey, who believes that advances in medical technology may some day enable #humans to live indefinitely. He spells out his ideas in this podcast, which could #change the way you think about aging.

Bioinspired robotics class offers intriguing surprises

Enter Kim’s class, 2.74 (Bio-Inspired Robotics).

According to Kim, researchers need to understand this cognitive bias, this tendency toward anthropomorphism, in order to even begin developing robots that can help humans with their physical movements. While Kim’s research interest is in building robots that could help people, such as the elderly in an aging population with fewer young people to perform services, such advancement is not even possible without understanding biology, biomechanics, and how much we don’t understand about our own everyday movements.

“One big thing students should learn in this class is not necessarily to understand how we move our body but the fact that we don’t understand how we move,” Kim says. “One of our ultimate goals in robotics is to develop robots that help elderly people by mimicking how we use our arms and legs, but if you don’t realize how little we know about how we move, we cannot even start tackling this problem.”

Muscle contractions release chemical signals that promote brain network development

Chemical signals from contracting muscles can influence the growth of brain networks, according to new research published in Neuroscience. The study highlights the importance of physical activity to mental health, and the findings could also help contribute to the development of more effective treatments for cognitive disorders such as Alzheimer’s disease.

Previous studies had shown that exercise has significant benefits for cognitive health, even when initiated at late stages in life. Exercise has been associated with long-term changes in the hippocampus, a brain region crucial for learning and memory, including increased neurogenesis, synaptogenesis, and enlarged volume.

However, the specific mechanisms through which exercise produces these changes in the hippocampus were not well understood. By uncovering these mechanisms, the authors behind the new study aim to develop exercise-based treatments for cognitive pathologies that affect the hippocampus, such as Alzheimer’s disease, stress, depression, anxiety, and normal aging.

Scientists discover “elixir of life” that slows aging

A common nutrient found in everyday foods might be the key to a long and healthy life, according to researchers from Columbia University.

The nutrient in question is taurine, a naturally occurring amino acid with a range of essential roles around the body.

Not only does the concentration of this nutrient in our bodies decrease as we age, but supplementation can increase lifespan by up to 12 percent in different species.

Eat Right And You Could Live Longer

Eating nutritious food has been shown time and time again to help improve metabolic health and delay aging. But what the appropriate quantities of these dietary macronutrients are has received somewhat varying results.

To investigate what they might be researchers from Waseda University fed isocaloric diets with varying amounts of protein to mice, and their findings are published in GeroScience. According to the researchers, the animals were found to be metabolically healthier when they were fed moderate protein diets, and these findings could provide insight into developing nutritional interventions as well as to improving metabolic health in people.

The types of food that we eat influence our health and longevity from the time we are born all the way through our time on this planet. There is a direct association between age-related nutritional requirements and metabolic health, and maintaining optimal nutrition according to age can help maintain metabolic health improving both healthspan and lifespan.

Google Engineer Turned Futurist Predicts AI-Enabled Immortality For Humans

Former Google engineer and esteemed futurist Ray Kurzweil has made another bold prediction: Immortality is within reach for humans by 2030, thanks to the help of nanorobots. You read that right — humans could potentially live forever, according to Kurzweil.

Kurzweil, who has a track record of accurate predictions such as foreseeing a computer beating humans in chess by 2000, shared his prediction in a recent YouTube series by tech vlogger Adagio. The 75-year-old computer scientist believes that advancements in genetics, robotics and nanotechnology will allow tiny robots to run through veins, repairing any damage and keeping people alive indefinitely.

Details of cellular process which stops cancer developing revealed

Researchers have for the first time characterised the molecular mechanism of the early stages of programmed cell death or apoptosis, a process which plays a crucial role in the prevention of cancer.

The study, published today (2 June) in Science Advances, was led by Dr Luke Clifton at the Science and Technology Facilities Council (STFC) ISIS Neutron and Muon Source (ISIS) in Oxfordshire. They worked alongside partners at the University of Umea and European Spallation Source in Sweden.

It is the most recent in a series of research collaborations by this team, investigating the cellular proteins responsible for apoptosis.
