Ageing is an incredibly complicated process, so much so that we do not yet understand exactly how complicated it is. It is in fact so complicated, that it could actually be incredibly simple. Confused? Well, imagine if you were a structural engineer who was trying to understand why a building collapsed. From an initial inspection of the rubble, it may be extremely difficult to work out exactly what went wrong. Was the building made from inferior materials? Was it built incorrectly? Was its destruction deliberate? Did it just fall apart due to age? All of these are possible, but what was the true cause for its destruction? Well, that is the same mystery we are trying to solve in longevity research. We can see the damage that is caused by ageing, but what is the cause? Is it a general accumulation of damage, or are there single points of failure which have knock on effects that affect the entire body? A cascade failure if you will.

Of the many different changes that occur during the ageing process, one of the most well-known and understood is the decreased capacity for our body to produced chemical energy, which has a knock-on effect throughout the body. This results in a general decrease in our ability to carry out cellular functions and will therefore effective everything from muscle strength to DNA replication and repair. This decrease in energy output has been linked to defects in our mitochondria, but in addition to these physical defects that occur in these small organisms, we now know that they also suffer a decreased capacity to carry out their function due to lacking a critical coenzyme called Nicotinamide adenine dinucleotide (NAD). Anyone who has taken a high school level biology class will probably recognise this enzyme as part of the electron transport chain in respiration.

The United states army are planning to test NAD+ dietary supplementation experiments next year in hopes of producing a viable method of increasing the viable length of a soldier’s active service.

“Deep in the forests of Germany, nestled neatly into the hollowed-out shells of acorns, live a smattering of ants who have stumbled upon a fountain of youth. They are born workers, but do not do much work. Their days are spent lollygagging about the nest, where their siblings shower them with gifts of food. They seem to elude the ravages of old age, retaining a durably adolescent physique, their outer shells soft and their hue distinctively tawny. Their scent, too, seems to shift, wafting out an alluring perfume that endears them to others. While their sisters, who have nearly identical genomes, perish within months of being born, these death-defying insects live on for years and years and years,” Katherine J. Wu writes.

A parasite gives its hosts the appearance of youth, and an unmatched social power in the colony.

Zoledronate is a biophosphonate, a drug used to strengthen bones and reduce the risk of osteoporosis-related bone fractures. It is well-absorbed into the bones, so it only needs to be administered through infusion once a year.

A 2010 study had found that people who were given zoledronate after experiencing hip fractures showed slightly reduced all-cause mortality compared to a control group. Patients who took the drug were at significantly lower risk for heart arrhythmias and pneumonia.

As this is a drug that is already being given to people, the choice to go back to genetically modified fruit flies, a much simpler model of aging, may seem counterintuitive. The team chose to test these insects for two principal reasons. The first is that Drosophila flies are a common subject of studies on basic aging pathways, which the researchers wished to explore. The second is simpler: Drosophila flies lack bones, making the bone-affecting properties of zoledronate irrelevant to the study.

It’s an astonishing achievement — and in an eyebrow-raising twist, Simons says he plans to live forever, by turning himself into a cyborg.

It sounds like Simons has thought out his plan.

“This is the first puzzle piece in my goal of replacing body parts with mechanical parts,” Simons told De Telegraaf, adding that his goal is “immortality.”
