  • The EPIC Systematic Review showed that chocolate lowered the risk of coronary heart disease by 25% and cardiovascular deaths by 45%.
  • Raw cocoa powder is lower in calories when compared to chocolate.
  • Cocoa has many antioxidants called flavonols, shown to be heart healthy.
  • Research suggests that cocoa reduces atrial fibrillation, improves cholesterol, benefits vascular health and reduces blood pressure.
  • Cocoa is the key ingredient in heart healthy chocolate.
  • Dark chocolate is also heart healthy and is higher in flavonols than cocoa powder. Dark chocolate has more fat.
  • Dark chocolate and cocoa powder both have their advantages.
  • To get the heart health benefits of chocolate without the extra calories, add a pure cocoa powder to foods you normally consume.

Four Ways We Can “Swallow the Doctor” (Nanodocs, the medical nanorobots)

Posted by in categories: biotech/medical, nanotechnology, robotics/AI

Summary: Nanodocs are medical nanorobots that work from inside like a tiny doctor. The authors of a recent research study say we may be able to swallow the doctor sooner than we think. Once considered science fiction, the ability to “swallow the surgeon” – using medical nanobots to diagnose and treat disease from inside the body – is becoming a reality. The study authors highlight recent advances in nanotechnology tools, such as nanodrillers, microgrippers, and microbullets – and show how nanodocs have tremendous potential in the areas of precision surgery, detection, detoxification and targeted drug delivery.

Imagine that you need to repair a defective heart valve, a major surgery. Instead of ripping your chest cut open, a doctor merely injects you with a syringe full of medical nanorobots, called nanodocs for short. You emerge from the ‘surgery’ unscathed, and your only external wound is the puncture hole from the injection.

According to a recent study published by nanorobotic engineers at the University of California San Diego (UCSD), the concept of ‘swallow the doctor’ may be closer to reality than we think.

Quantum computers ‘one step closer’

Posted by in categories: computing, particle physics, quantum physics

Quantum computing has taken a step forward with the development of a programmable quantum processor made with silicon.

The team used microwave energy to align two electron particles suspended in silicon, then used them to perform a set of test calculations.

By using silicon, the scientists hope that quantum computers will be more easy to control and manufacture.

Anti-Aging Scientists Hope to Reduce Chronic Diseases

Posted by in categories: biotech/medical, life extension, neuroscience

Summary: Recent scientific advances in anti-aging science are bringing the dream of the fountain of youth closer to reality. More than just extending our lifespans, the field hopes to significantly reduce the chronic diseases of aging, such as cancer, heart disease, and dementia. [This article first appeared on the website Author: Brady Hartman. ]

A fountain of youth has been the dream of humanity throughout history.

Recent scientific advances are bringing that dream closer to reality.

Secrets of these 200-year-old whales who avoid cancer

Posted by in categories: biotech/medical, life extension

Summary: Why the bowhead whale lives 200 years and rarely gets cancer. This article is part 2 of a 3-part series, covering the role of telomere length in cancer and part of a new extensive study. Part 1 on the accuracy of telomere length is here, Part 3 on the role of telomere length in chronic diseases is here. [This article first appeared under the title ‘Top Journal Discovers Key to These 200-Year-Old Whales Who Avoid Cancer’ on the website Author: Brady Hartman. ]

Related: A brief overview of why whales don’t get cancer is in this companion video.

In a comprehensive study published a little more than a week ago in a highly respected journal of the Royal Society of the UK, authors Abraham Aviv and Jerry W. Shay (see author bios here) report on the role of telomere length. In this segment, the authors describe the role of telomere length in protecting us from cancer and explain why whales have low rates of cancer, despite large cell counts, long lives, and relatively short telomeres.

Can the blood of teens rejuvenate our bodies? This new trial aims to find out

Posted by in categories: biotech/medical, life extension, neuroscience

Summary: A recently announced parabiosis trial in humans – the practice of transfusing young blood to old – may have profound implications for treating the chronic diseases of old age, including metabolic changes, frailty, Alzheimer’s, Parkinson’s, and other forms of dementia. However, some geroscientists say that variations of the procedure could cause severe side effects. [This article first appeared on the website Author: Brady Hartman. ]

The idea that youthful blood might rejuvenate our aging bodies has lingered in the popular imagination for centuries, fueled by recent experiments in which these transfusions revitalized aging mice.

Last week, Bill Faloon of the Life Extension Foundation (LEF) in partnership with the Young Blood Institute (YBI), announced a bold new human trial of the rejuvenating effects of the young blood / old blood swap, saying.

Revolutionary Technologies to Beat Aging in Our Lifetimes

Posted by in categories: biotech/medical, life extension

Five technologies in development – including senolytic drugs, rapamycin, stem cell therapy, NAD supplementation and gene therapy – could dramatically slow down aging in the next few years. This report updates the latest developments in these promising and potentially lifespan-extending treatments. [This article first appeared on the website LongevityFacts. Author: Brady Hartman. ]

The longevity science field has made enormous progress in recent years, and human trials of anti-aging compounds have already started, with more to begin soon. The lifespan-extension research field is gaining the attention of mainstream medicine.

The specialists who populate the field, called geroscientists, are developing several technologies that might benefit people who are alive today and aim to bring them to the clinic. These lifespan-extending technologies include stem cell therapy, rapamycin, gene therapy, senolytic drugs, and NAD supplementation.

World’s Largest Plane Could Give Elon Musk The Space Race He’s Craving

Posted by in categories: Elon Musk, space, sustainability, transportation

Image: Stratolaunch Billionaires are taking to space the way wistful young men take to the sea in 19th Century novels. Last week, Elon Musk launched his Tesla Roadster at the astroid belt using the world’s most powerful rocket currently in operation. Not to be outdone, Microsoft’s co-founder Paul Allen also has a big plan (and a big plane) for going to space. In December of last year, the Stratolaunch performed its first taxi at the Mojave Air & Space Port in Mojave, CA. While that doesn’t seem terribly exciting, it’s the first step to getting the Stratolaunch, the world’s largest plane eve…
