Vision restored: Retinal therapy research marks first successful induction of long-term neural regeneration

Vision is one of the most crucial human senses, yet more than 300 million people worldwide are at risk of vision loss due to various retinal diseases. While recent advancements in retinal disease treatments have successfully slowed disease progression, no effective therapy has been developed to restore already lost vision—until now.

KAIST researchers led by Professor Jinwoo Kim from the Department of Biological Sciences have successfully developed a novel drug to restore vision through retinal nerve regeneration. The research is published in the journal Nature Communications. The study was co-authored by Dr. Eun Jung Lee of Celliaz Inc. and Museong Kim, a Ph.D. candidate at KAIST, as joint first authors.

The research team successfully induced neural regeneration and vision rec...

Entwined dwarf stars reveal their location thanks to repeated radio bursts

We now know it isn’t just neutron stars that emit such pulses. A white dwarf and a red dwarf star have been discovered closely orbiting each other emitting radio pulses every two hours. Their findings means we know it isn’t just neutron stars that emit such pulses, but these are spaced unusually far apart.

An international team of astronomers led by Dr Iris de Ruiter, now at the University of Sydney, has shown that a white dwarf and a red dwarf star orbiting each other every two hours are emitting radio pulses.

Thanks to follow-up observations using optical and x-ray telescopes, the researchers were able to determine the origin of these pulses with certainty. The findings explain the source of such radio emissions found across the Milky Way galaxy for the first time.

The resu...

New research by a team of Indiana University School of Medicine scientists and their collaborators has uncovered a novel vulnerability in prostate cancer animal models that starves prostate tumors of critical nutrients and stunts their growth, which could lead to the development of new treatments for the deadly disease.

Led by IU School of Medicine’s Kirk Staschke, Ph.D., assistant research professor of biochemistry and molecular biology, and Ronald C. Wek, Ph.D., Showalter Professor of Biochemistry, the study was recently published in Science Signaling.

LEDs based on transition metal dichalcogenides displaying reduced efficiency losses

Light-emitting diodes (LEDs), semiconductor-based devices that emit light when an electric current flows through them, are key building blocks of numerous electronic devices. LEDs are used to light up smartphone, computer, and TV displays, as well as light sources for indoor and outdoor environments.

Past studies consistently observed a decline in the performance and efficiency of LED devices based on two-dimensional (2D) materials at high current densities. This loss of efficiency at high current densities has been linked to high levels of interaction between excitons, which cause a process known as exciton-exciton annihilation (EEA).

Essentially, the properties of some 2D materials...
