Hall effect in a moving liquid

Posted by in category: futurism

A simple experiment, suitable for performing in an undergraduate physics laboratory, illustrates electromagnetic induction through the water entering into a cylindrical rubber tube by detecting the voltage developed across the tube in the direction transverse both to the flow velocity and to the magnetic field. The apparatus is a very simple example of an electromagnetic flowmeter, a device which is commonly used both in industrial and physiological techniques. The phenomenology observed is similar to that of the Hall effect in the absence of an electric current in the direction of motion of the carriers. The experimental results show a dependence on the intensity of the magnetic field and on the carrier velocity, in good agreement with the theory. Discussion of the system, based on classical electromagnetism, indicates that the effect depends only on the flow rate, and is independent both of the velocity profile and of the electrical conductivity of the medium.

Quantum tunnelling in water opens the way to improved biosensing

Posted by in categories: biological, quantum physics

Circa 2017 A magnonic holographic matrix could be used to essentially treat the water in a solid-state way.


Researchers at the University of Sydney have applied quantum techniques to understanding the electrolysis of water, which is the application of an electric current to H2O to produce the constituent elements hydrogen and oxygen.

They found that electrons can ‘tunnel’ through barriers in away from the electrodes, neutralising ions of impurities in that . This can be detected in changes in current, which has applications for biosensing, the detection of biological elements in solution.

Leading geneticist says reversing the aging process in humans could be 20 years away

“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.

Dramatically Enhanced Spin Dynamo with Plasmonic Diabolo Cavity

Posted by in categories: futurism, particle physics

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.

Ancient worm reveals way to destroy toxic cells in Huntington’s disease

Posted by in category: biotech/medical

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 , proteins that have amassed due to a malfunction in the process of ‘folding’ that determines their shape.

Their findings were published in eLife today.

Sickness like mad cow disease is spreading in deer — and could infect humans

Posted by in categories: biotech/medical, neuroscience

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.
