There’s One Way Time Travel Could Be Possible, According to This Physicist

Posted by in categories: physics, time travel

Have you ever made a mistake that you wish you could undo? Correcting past mistakes is one of the reasons we find the concept of time travel so fascinating. As often portrayed in science fiction, with a time machine, nothing is permanent anymore – you can always go back and change it. But is time travel really possible in our universe, or is it just science fiction?

Our modern understanding of time and causality comes from general relativity. Theoretical physicist Albert Einstein’s theory combines space and time into a single entity – “spacetime” – and provides a remarkably intricate explanation of how they both work, at a level unmatched by any other established theory.

Physicists Developed a Superconductor Circuit Long Thought to Be Impossible

Posted by in categories: quantum physics, supercomputing

By exchanging a classical material for one with unique quantum properties, scientists have made a superconducting circuit that’s capable of feats long thought to be impossible.

The discovery, made by researchers from Germany, the Netherlands, and the US, overturns a century of thought on the nature of superconducting circuits, and how their currents can be tamed and put to practical use.

Low-waste, high-speed circuits based on the physics of superconductivity present a golden opportunity to take supercomputing technology to a whole new level.

Japan university tackles aging with transplanted pluripotent stem cells

Posted by in categories: biotech/medical, life extension

A research team from Osaka University in Japan has concluded that a clinical trial of transplanted IPS cell-derived corneal tissue was safe and effective – further evidence that cellular reprogramming with Yamanaka factors is moving towards scalable therapies.

Longevity. Technology: The clinical trial spanned several years and used corneal tissues derived from induced pluripotent stem cells. The tissue was transplanted into four almost-blind patients, and, according to the research team, none of the patients experienced rejection or tumorigenicity of the transplanted cells and all saw improvements in their symptoms, with three experiencing improved eyesight, with one improving from 0.15 to 0.7. Importantly, all were free of side effects one year later.

IPS cells can be generated from any adult cell, with Yamanaka factors – a group of protein transcription factors from four master genes. These induced stem cells demonstrate the significant quality of pluripotency – they can differentiate into all other cell types of the body. This is incredibly useful both for research and for therapy.

Yale scientists find the causes of cancer

Posted by in categories: biotech/medical, evolution

Yale researchers can now quantify the factors causing changes in the DNA that contribute most to cancer growth in tumors of most major tumor types.

The new molecular analysis approach brings clarity to a longstanding debate over how much control humans have over developing cancer across time.

The study was published in Molecular Biology and Evolution.
