Discovery opens door to efficient research model. Washington State University researchers have seen how both humans and fruit flies deploy a protein that plays a critical role in their immune responses to invading bacteria. The discovery gives scientists a model organism with which to explore ways to boost the human immune system and create infection-fighting medicines.

Naturally, there are enormous differences between humans and fruit flies, whose common ancestor goes back 800 million years...

In the new quantum information technologies, fragile quantum states have to be transferred between distant quantum bits. Researchers have now realized such a quantum transmission between two solid-state qubits at the push of a button. At the ETH in Zurich, a team of physicists led by Andreas Wallraff of the Laboratory for Solid State Physics has now succeeded in transmitting quantum information, at the push of button and with high fidelity, between two quantum bits roughly a metre apart.

The main peculiarity of quantum information technologies, such as quantum computers and quantum cryptography, is the use of...

The purple-white source in the lower left shows X-ray emission from the remains of a star that was ripped apart as it fell towards an intermediate mass black hole. The host galaxy of the black hole is located in the middle of the image. Credit: X-ray: NASA/CXC/UNH/D.Lin et al, Optical: NASA/ESA/STScI

Scientists have been able to prove the existence of small black holes and those that are super-massive but the existence of an elusive type of black hole, known as intermediate-mass black holes (IMBHs) is hotly debated...

A KAIST research team developed a crucial source technology that will advance the commercialization of micro LEDs. Professor Keon Jae Lee from the Department of Materials Science and Engineering and his team have developed a low cost production technology for thin-film blue flexible vertical micro LEDs (f-VLEDs).

In CES 2018, micro LED TV was spotlighted as a strong candidate for replacing the active-matrix organic light-emitting diode (AMOLED) display. Micro LED is a sub-100 um light source for red, green and blue light, which has advantages of outstanding optical output, ultra-low power consumption, fast response speed, and excellent flexibility.

However, the current display industry has utilized the individual ...
