The new technology, which was created at the University of Turku and developed by the company CardioSignal, uses a smartphone to analyse heart movement and detect heart failure. The study involved five organisations from Finland and the United States.

Heart failure is a condition affecting tens of millions of people worldwide, in which the heart is unable to perform its normal function of pumping blood to the body.

It is a serious condition that develops as a result of a number of cardiovascular diseases and its symptoms may require repeated hospitalisation.

Heart failure is challenging to diagnose because its symptoms, such as shortness of breath, abnormal fatigue on exertion, and swelling, can be caused by a number of conditions.

There is no simple test available to dete...

Going beyond the anti-laser may enable long-range wireless power transfer. Charging a smartphone wirelessly nowadays is not a big deal. You have to put your smartphone on a charging pad. But usable long-range wireless power transfer, like from one room to another or even across the building, is still in progress.

Most of the development methods involve focusing narrow beams of energy and aiming them at their intended target. These methods have had some success but are, so far, not very efficient. And having focused electromagnetic beams flying around through the air is unsettling.

Scientists from the University of Maryland (UMD), in collaboration with a colleague at Wesleyan University in Connecticut, have developed an improved technique for wireless power transfer...

University of Central Florida Assistant Professor Debashis Chanda and physics PhD student Daniel Franklin have made a breakthrough that could produce much higher resolution for TVs, smartphones and other video screens.

Researchers at the University of Central Florida have developed a new color changing surface tunable through electrical voltage – a breakthrough that could lead to 3X the resolution for televisions, smartphones and other devices. With current technology, each of the pixels contain 3 subpixels – one red, one green, one blue. Assistant Professor Debashis Chanda and physics doctoral student Daniel Franklin have come up with a way to tune the color of these subpixels...

A recent study from Uppsala University shows how smartphones can be used to make movies of living cells, without the need for expensive equipment. The study is published in the open access journal PLOS ONE, making it possible for laboratories around the world to do the same thing.

Live imaging of cells is a very powerful tool for the study of cells, to learn about how cells respond to different treatments such as drugs or toxins. However, microscopes and equipment for live imaging are often very expensive.

In the present study, old standard inverted microscopes that are very abundant at Universities and hospitals were upgraded to high quality live imaging stations using a ...
