Maybe we don"t see aliens because they"re waiting to hear a signal from us first
We've had a long-running series here at UT on potential solutions Fermi paradox—why aren't we able to detect any alien life out there in the Universe? But more possible solutions are being developed all the time. Now, another paper adds some additi.....»»
Study finds well-known enzyme also performs quality control of membrane proteins
An interdisciplinary team of scientists from Cologne, Heidelberg and Munich have discovered a new function of a well-known enzyme. The signal peptidase complex in the endoplasmic reticulum cleaves faulty membrane proteins to initiate their degradatio.....»»
Broadband low-loss all-optical phase modulator using gas-filled hollow-core fiber
Optical phase modulators are key components in optical communication, sensing, and signal processing systems. All-optical modulators, which modulate the phase or intensity of a light signal by a control light beam, have attracted much research intere.....»»
