“Aging reversal is something that’s been proven about eight different ways in animals,” geneticist George Church says. So when will humans get to turn back the clock? Church tells 60 Minutes it’s not that far away. See the full report, Sunday.
The applications of spin dynamos, which could potentially power complex nanoscopic devices, have so far been limited owing to their extremely low energy conversion efficiencies. Here, we present a unique plasmonic diabolo cavity (PDC) that dramatically improves the spin rectification signal (enhancement of more than three orders of magnitude) under microwave excitation; further, it enables an energy conversion efficiency of up to ~0.69 mV/mW, compared with ~0.27 μV/mW without a PDC. This remarkable improvement arises from the simultaneous enhancement of the microwave electric field (~13-fold) and the magnetic field (~195-fold), which cooperate in the spin precession process generates photovoltage (PV) efficiently under ferromagnetic resonance (FMR) conditions. The interplay of the microwave electromagnetic resonance and the ferromagnetic resonance originates from a hybridized mode based on the plasmonic resonance of the diabolo structure and Fabry-Perot-like modes in the PDC. Our work sheds light on how more efficient spin dynamo devices for practical applications could be realized and paves the way for future studies utilizing both artificial and natural magnetism for applications in many disciplines, such as for the design of future efficient wireless energy conversion devices, high frequent resonant spintronic devices, and magnonic metamaterials.
In 2007, Y. S. Gui, et al.1 first proposed and demonstrated the spin dynamo, first proposed and demonstrated the spin dynamo, is constructed that provides a new and interesting way to generate direct current via spin precessions to locally power nanoscopic devices and for future applications such as wireless energy conversion. Compared with the spin-driven currents in semiconductors2, spin dynamos are based on ferromagnetic materials1 or spin-torque diodes3, 4, which feature a much higher current/power ratio coupled with a much smaller internal resistance. However, the reported works are limited to sophisticated waveguide couplings (and therefore to wires), such as coplanar waveguides (CPWs)5, 6, microstrip lines7, 8, and bias Tees3, 9 –12, to in-couple radio-frequency or microwave electromagnetic waves. Free space direct illumination has rarely been studied, despite its excellent suitability for wireless energy conversion.
Insights from their study may provide a novel therapeutic approach for diseases such as Huntington’s and Parkinson’s.
Associate Professor Roger Pocock, from the Monash Biomedicine Discovery Institute (BDI), and colleagues from the University of Cambridge led by Professor David Rubinsztein, found that microRNAs are important in controlling protein aggregates, proteins that have amassed due to a malfunction in the process of ‘folding’ that determines their shape.
Their findings were published in eLife today.
The Kardashev Scale ranks civilisations based on how advanced they are… and, according to Carl Sagan, humans are currently Type Zero! So, what would happen if humanity reached Type I on the Kardashev Scale? What sorts of technologies would be available to us? And how different would our lives be? In this video, Unveiled finds out…
This is Unveiled, giving you incredible answers to extraordinary questions!

Tasuku Honjo, distinguished professor at Kyoto University, has won the 2018 Nobel Prize in physiology and medicine for his discovery of a protein that helped lead to immunotherapeutic methods of cancer treatment, the Karolinska Institute in Sweden announced on Oct. 1.
A DEADLY infection similar to mad cow disease is spreading in deer — and could infect humans, experts have warned.
Officials are monitoring cases of chronic wasting disease (CWD), which attacks the brain, spinal cord and other tissue, in North America.
The US Centers for Disease Control and Prevention (CDC) says the disease — sometimes referred to as ‘zombie deer’ — has now spread to at least 26 states.

The two chimera piglets died within a week of being born. They were created after more than 4,000 attempts to implant embryos into sows. Research was carried out in Beijing, China.
Quadratic equations are polynomials, meaning strings of math terms. An expression like “x + 4” is a polynomial. They can have one or many variables in any combination, and the magnitude of them is decided by what power the variables are taken to. So x + 4 is an expression describing a straight line, but (x + 4)² is a curve. Since a line crosses just once through any particular latitude or longitude, its solution is just one value. If you have x², that means two root values, in a shape like a circle or arc that makes two crossings.
