The eyes are not only a mirror of a soul, but also a medical record. Their thermal radiation can indicate a disease even before clinical signs appear. Investigations in this area conducted by Russian scientists have been supported by the research program of the Russian Academy of Sciences called “Abstract Sciences for Medicine”.
Russian biophysicists under the guidance of G.R. Ivanitsky, Corresponding Member of the Russian Academy of Sciences, are developing the system for rapid disease diagnostics by eyes thermal radiation. The method may be particularly useful during epidemic when it is necessary to assess promptly the state of health of the people coming from infected regions, this being done directly at railway stations and airports.
Physicians have always taken the patients’ temperature. This is a rather reliable indicator of the state of health, although some diseased are not accompanied by noticeable rise in temperature. The thermometer is usually placed under the tongue, in the armpit, in the external acoustic meatus or the rectum. Such methods do not suit for remote rapid diagnostics of people in a crowd. Instead of a traditional thermometer, Russian researchers suggested to use cameras recording infrared radiation of people, which would allow to take temperature promptly at a distance. Infrared cameras determine the temperature with precision of up to several hundredth of a degree. During mass diagnostics, it is most convenient to take the temperature of face – a constantly open part of the body. The warmest part of the face is eyes. The eye glow more intensely than the skin in the infra-red range, as they contain six hard-working muscles each, a ramified blood supply system and lachrymal glands. The temperature in the vicinity of eyes normally reaches 36.5 degrees C.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
