Scientists have carried out trials using microscopic drones that could be used to seek and repair damaged arteries, preventing heart attacks and strokes.

Researchers have completed the first successful tests of nanoparticles – which are targeted to go where they are needed – in mice, and hope to soon to conduct the first patient trials.

The nanoparticles are designed to latch on to hard plaques in the arteries, made from fat cholesterol and calcium, which cause heart disease.

Once they reach their target, the “drones” release a drug derived from a natural protein that repairs inflammation damage in the body.

Each of the tiny particles, made from a plastic-like material, is 1,000 times smaller than the tip of a human hair.

Scientists said the use of nanotechnology could herald an “exciting” breakthrough for patients with heart disease, and could also assist with other areas of medicine.

In the tests, atherosclerosis [clogged arteries] in laboratory mice was significantly repaired after five weeks of treatment and plaques were stabilised, making it less likely for fragments to break off and clog blood vessels.

Lead researcher Dr Omid Farokhzad, director of the Laboratory of Nanomedicine and Biomaterials at Brigham and Women’s Hospital in Boston, US, said: “This is the first example of a targeted nanoparticle technology that reduces atherosclerosis in an animal model.”

After years of research and a series of unpleasant experiences concerning the current child protection services system, Alec Cope decided to combat the cancerous corruption through information. Freelance writing articles as a form of protest and distributing them throughout his former high-school and local area, Alec struck special chords with whomever he was in contact with.

Alec has been involved in activism such as sit down protests as well as Idle No More gatherings. Being independent for the majority of his time, Alec became a member of the WeAreChange family to assist one of the organizations that inspired him to become active in the first place. With a larger platform and positive support Alec has committed the majority of his time to research, writing, and maintaining social media with the goal to continue expanding the awakening sweeping throughout all levels of society.

Growing up within a rural area in Northern Michigan as well as being a native American descendant, Alec is seeking to expose environmental abuse in his state as well as globally. A high-school dropout, Alec chases his passion for writing and empowering individuals while showing any isolated person that they too can overcome the odds with a community that will support them. Alec lives in the lower peninsula of Michigan near Kalamazoo.
