AI improves speech understanding of hearing aid users

14/07/2021

In noisy environments, it is difficult for hearing aid or hearing implant users to understand their conversational partner because current audio processors still have difficulty focusing on specific sound sources. In a study, researchers from the Hearing Research Laboratory at the University of Bern and the Inselspital are now suggesting that artificial intelligence could solve this problem.

New electronic paper displays brilliant colors

13/07/2021

Imagine sitting out in the sun, reading a digital screen as thin as paper, but seeing the same image quality as if you were indoors. Thanks to research from Chalmers University of Technology, Sweden, it could soon be reality. A new type of reflective screen - sometimes described as electronic paper - offers optimal colour display, while using ambient light to keep energy consumption to a minimum.

New AI tech for early detection of prostate cancer

08/07/2021

Prostate cancer is the most diagnosed cancer and a leading cause of death by cancer in Australian men. Early detection is key to successful treatment but men often dodge the doctor, avoiding diagnosis tests until it's too late. Now an artificial intelligence (AI) program developed at RMIT University in Melbourne, Australia could catch the disease earlier.

First-ever transient pacemaker harmlessly dissolves in body

29/06/2021

Researchers at Northwestern and George Washington (GW) universities have developed the first-ever transient pacemaker -- a wireless, battery-free, fully implantable pacing device that disappears after it's no longer needed.

Using AI to track cognitive deviation in aging brains

25/06/2021

Researchers have developed an artificial intelligence (AI)-based brain age prediction model to quantify deviations from a healthy brain-aging trajectory in patients with mild cognitive impairment, according to a study published in Radiology: Artificial Intelligence.

Super-resolution brain imaging

16/06/2021

Light can bend around the corners of obstacles found along its path. Because of this phenomenon, called diffraction, it is impossible to focus light onto a spot that is smaller than half its wavelength. The highest resolution one can theoretically achieve using an optical microscope is approximately 250 nm. Unfortunately, this resolution is not enough for observing structures found in neurons.

New tool activates deep brain neurons by combining ultrasound, genetics

03/06/2021

Electrical engineers at the University of California San Diego developed a technology that improves the resolution of an ordinary light microscope so that it can be used to directly observe finer structures and details in living cells.

A novel technology for cooperative analysis of Big Data

28/05/2021

Communities benefit from sharing knowledge and experience among their members. Following a similar principle - called "swarm learning" - an international research team has trained artificial intelligence algorithms to detect blood cancer, lung diseases and COVID-19 in data stored in a decentralized fashion.

Technique uses fluctuations in video pixels to measure energy use of developing embryos

25/05/2021

Scientists have made a breakthrough in the study of embryonic development and how it can be impacted by external factors such as climate change. Researchers at the University of Plymouth have developed a cutting edge technique which enables them to instantly examine the biological traits and behaviours of developing embryos as an energy signature, rather than focusing on individual characteristics

Making the invisible visible

21/05/2021

Researchers from Friedrich Schiller University Jena, the University of California Berkeley and the Institut Polytechnique de Paris use intense laser light in the extreme ultraviolet spectrum to generate a non-linear optical process on a laboratory scale – a process which until now has only been possible in a large-scale research facility.

AI doctors: Patients may not take advice

11/05/2021

Researchers from Penn State and University of California, Santa Barbara (UCSB) found that people may be less likely to take health advice from an AI doctor when the robot knows their name and medical history. On the other hand, patients want to be on a first-name basis with their human doctors.

App for better obstetric communication

05/05/2021

Researchers at Jacobs University Bremen have now developed a German language app that aims to improve communication in obstetrics. It addresses expectant mothers, their relatives, and medical staff – especially midwives, whose work will be honored on May 5, 2021, with the International Day of the Midwife.

Better hearing with optical cochlear implants

27/04/2021

Understanding spoken words, developing normal speech - cochlear implants enable people with profound hearing impairment to gain a great deal in terms of quality of life. However, background noises are problematic, they significantly compromise the comprehension of speech of people with cochlear implants. The team led by Tobias Moser is therefore working to improve cochlear implants.
