Technology has many beneficial effects on modern people’s lives, and one of them is to prolong our lifespan through advancing the medical field. In the past few years, new techniques such as artificial intelligence, robots, wearable tech, and so on have been used to improve the quality of our healthcare system, and some even newer innovations such as flying vehicles and brain computer interface are also considered valuable to the field. In this article, we will first give a thorough discussion about how these new technologies will shape our future healthcare, and then some upcoming problems that we may soon face will be addressed.

The movements of cell muscles in the form of tiny filaments of proteins have been visualised at unprecedented detail by University of Warwick scientists.

In a study published in the Biophysical Journal, scientists from the University’s Department of Physics and Warwick Medical School have used a new microscopy technique to analyse the molecular motors inside cells that allow them to move and reshape themselves, potentially providing new insights that could inform the development of new smart materials.

Myosin is a protein that forms the motor filaments that give a cell stability and are involved in remodelling the actin cortex inside the cell. The actin cortex is much like the backbone of the cell and gives it its shape, while the myosin filaments are similar to muscles. By ‘flexing’, they enable the cell to exert forces outside of it and to propagate.

Scientists have developed a precise, nanotechnology-based treatment to alleviate the pain and fertility problems associated with endometriosis, a common gynecological condition in women of childbearing age.

Research led by Oleh Taratula of the Oregon State University College of Pharmacy and Ov Slayden of the Oregon National Primate Research Center at Oregon Health & Science University used photo-responsive nanoparticles loaded with dye to find and remove the lesions associated with the disorder.

Findings were published today in the journal Small.

:oooo.

A single nanoparticle is just 300 nanometers wide, but an array of them create what’s called a metamaterial with superior capabilities. Researchers used this tech to create better night vision goggles powered by nanocrystals, which can convert photons of infrared light into visible light.

Vin Diesel stars as Ray Garrison, a soldier recently killed in action and brought back to life as the superhero Bloodshot by the RST corporation. With an army of nanotechnology in his veins, he’s an unstoppable force –stronger than ever and able to heal instantly. But in controlling his body, the company has sway over his mind and memories, too. Now, Ray doesn’t know what’s real and what’s not – but he’s on a mission to find out.

Lipid nanoparticles containing genetic drugs can be bioengineered to tune their biodistribution and induce organ-specific gene regulation.

In novel concepts of magnetic data storage, it is intended to send small magnetic bits back and forth in a chip structure, store them densely packed and read them out later. The magnetic stray field generates problems when trying to generate particularly tiny bits. Now, researchers at the Max Born Institute (MBI), the Massachusetts Institute of Technology (MIT) and DESY were able to put an “invisibility cloak” over the magnetic structures. In this fashion, the magnetic stray field can be reduced in a fashion allowing for small yet mobile bits. The results were published in Nature Nanotechnology.

For physicists, magnetism is intimately coupled to rotating motion of electrons in atoms. Orbiting around the atomic nucleus as well as around their own axis, electrons generate the magnetic moment of the atom. The magnetic stray field associated with that magnetic moment is the property we know from e.g. a bar magnet we use to fix notes on pinboard. It is also the magnetic stray field that is used to read the information from a magnetic hard disk drive. In today’s hard disks, a single magnetic bit has a size of about 15 × 45 nanometer, about 1,000,000,000,000 of those would fit on a stamp.

One vision for a novel concept to store data magnetically is to send the magnetic bits back and forth in a memory chip via current pulses, in order to store them at a suitable place in the chip and retrieve them later. Here, the magnetic stray field is a bit of a curse, as it prevents that the bits can be made smaller for even denser packing of the information. On the other hand, the magnetic moment underlying the stray field is required to be able to move the structures around.

Research involving bowhead whales has suggested that it may one day be possible to extend the human lifespan to 200 years.

From the demigods of Greek mythology to the superheroes of 20th century comic books, we’ve been intrigued by the idea of human enhancement for quite a while, but we’ve also worried about negative consequences. Both in the Greek myths and modern comics and television, each enhanced human has been flawed in some way.

It’s been said that quantum computing will be like going from candlelight to electric light in the way it will transform how we live. Quite a picture, but what exactly is quantum computing?

For the answer to that question, we’ll have to visit a scale of existence so small that the usual rules of physics are warped, stretched and broken, and there are few layperson terms to lean on. Strap yourself in.

Luckily, we have a world-leading researcher in quantum computing, Professor David Reilly, to guide us. “Most modern technologies are largely based on electromagnetism and Newtonian mechanics,” says Reilly in a meeting room at the University’s Nano Hub. “Quantum computing taps into an enormous new area of nano physics that we haven’t harnessed yet.”
