TSU physicists are investigating the effects of radiation on DNA

Scientists from TSU's Laboratory of Experimental High Energy Physics and their colleagues from the University of Bordeaux are studying new ways of modeling the effects of low doses of radiation at the cellular level. For the first time, physicists will simulate the effects of radiation on DNA and calculate the probability of developing cancer in various chemical and biological environments.

How loud is too loud when it comes to sports whistles?

How loud is too loud when it comes to whistle tweets? Referees and others using whistles on the job need a simple way to determine whether it's harmful to their hearing, so a group of researchers set out to put it to the test and to provide some clarity and damage risk criteria for impulse noise exposures.

Virutally energy-free superfast computing invented by scientists using light pulses

A new invention uses magnets to record computer data which consume virtually zero energy, solving the dilemma of how to create faster data processing speeds without high energy costs.

Quantum cloud computing with self-check

With a quantum coprocessor in the cloud, physicists have opened the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. In a new study, researchers report how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.

Energy-free superfast computing invented by scientists using light pulses

Superfast data processing using light pulses instead of electricity has been created by scientists.

Holographic imaging of electromagnetic fields using electron-light quantum interference

In conventional holography a photographic film can record the interference pattern of monochromatic light scattered from the object to be imaged with a reference beam of un-scattered light. Scientists can then illuminate the developed image with a replica of the reference beam to create a virtual image of the original object. Holography was originally proposed by the physicist Dennis Gabor in 1948 to improve the resolution of an electron microscope, demonstrated using light optics.

Generating high-quality single photons for quantum computing

Researchers have designed a way to generate, at room temperature, more single photons for carrying quantum information. The design, they say, holds promise for the development of practical quantum computers.

Electrode's 'hot edges' convert carbon dioxide gas into fuels and chemicals

A team of scientists has created a bowl-shaped electrode with 'hot edges' which can efficiently convert carbon dioxide from gas into carbon based fuels and chemicals, helping combat the climate change threat posed by atmospheric carbon dioxide.

A step towards probabilistic computing

Researchers demonstrate how skyrmions can be used for future computer concepts that are closer to how the human brain works.

Accelerating quantum technologies with materials processing at the atomic scale

An emerging suite of information technologies based on fundamental quantum physics has been given a boost by researchers who have invented a method to engineer single atomic defects in diamond using laser processing.
