• Absolute vs. relative efficiency: How efficient are blue LEDs, actually? May 26, 2023
  The absolute internal quantum efficiency (IQE) of indium gallium nitride (InGaN) based blue light-emitting diodes (LEDs) at low temperatures is often assumed to be 100%. However, a new study has found that the assumption of always perfect IQE is wrong: the IQE of an LED can be as low as 27.5%.
• Using AI, scientists find a drug that could combat drug-resistant infections May 25, 2023
  Using AI, researchers identified a new antibiotic that can kill Acinetobacter baumannii, a type of bacteria that is responsible for many drug-resistant infections.
• Research offers clues for potential widespread HIV cure in people May 25, 2023
  New animal research is helping explain why at least five people have become HIV-free after receiving a stem cell transplant, and may bring scientists closer to developing what they hope will be a widespread cure for the virus that causes AIDS. A new study describes how two nonhuman primates were cured of the monkey form […]
• Astronomers discover a key planetary system to understand the formation mechanism of the mysterious 'super-Earths' May 25, 2023
  A study presents the detection of a system of two planets slightly larger than Earth orbiting a cold star in a synchronized dance. Named TOI-2096, the system is located 150 light-years from Earth. This system, located 150 light-years from Earth, is one of the best candidates for a detailed study of their atmosphere with the […]
