A pioneering international project led by prominent female scientists, involving research staff from the Universidad Carlos III de Madrid (UC3M) and promoted by the Spanish Space Agency (AEE), has just completed its parabolic flight campaign in Bordeaux (France). Its main objective is to study and counteract the adverse effects of microgravity on the human body, a key challenge for future exploration of the Moon and Mars.

While fiber Bragg grating is widely used for selectively filtering wavelengths during optical transmission, existing techniques are unsuitable for bandwidth filtering of broadband optical signals. Researchers have now demonstrated that chirped and tilted fiber Bragg grating (CTFBG) using femtosecond laser line-by-line technology can facilitate highly specific and versatile bandwidth filtering in broadband signals. The technique may offer several added advantages in optical signal filtering beyond flexibility and customizability.

A research team at the University of Missouri is working to predict which patients will benefit most from a specific type of cartilage transplant surgery, and some of the best clues may lie in patients’ urine.
