With modern electronic devices approaching the limits of Moore's law and the ongoing challenge of power dissipation in integrated circuit design‚ there is a need to explore alternative technologies beyond traditional electronics. Spintronics represents one such approach that could solve these issues and offer the potential for realizing lower-power devices.

You suddenly feel sick—pathogenic bacteria have managed to colonize and spread in your body. The weapons they use for their invasion are harmful toxins that target the host's defense mechanisms and vital cell functions. Before these deadly toxins can attack host cells‚ bacteria must first export them from their production site—the cytoplasm—using dedicated secretion systems.

Researchers at the University Medical Center Göttingen (UMG) have discovered a new quality control mechanism that regulates energy production in human cells. This process takes place in mitochondria‚ the power plants of the cell.

Working in the terahertz (THz) range offers unique opportunities in various applications‚ including biomedical imaging‚ telecommunications‚ and advanced sensing systems. However‚ because of the unique properties of electromagnetic waves in the 0.1 to 10 THz range‚ it has proven difficult to develop high-performance components that showcase the true potential of THz technology. Even the design of basic and essential elements like filters and absorbers remains a substantial challenge.

Several recent experiments identify unusual patterns in particle diffusion‚ hinting at some underlying complexity in the process which physicists have yet to discover. Through new analysis published in The European Physical Journal B‚ Adrian Pacheco-Pozo and Igor Sokolov at Humboldt University of Berlin show how this behavior emerges through strong correlations between the positions of diffusing particles traveling along similar trajectories.

As Earth records its hottest year ever‚ a global research collaboration has found warmer temperatures are a key driver in woody vines taking over the world's forests—threatening their vital role in helping cool the atmosphere by storing carbon.

In studying social mobility in today's industrialized nations‚ researchers typically rely on data from the World Economic Forum or‚ in the United States‚ the General Social Survey. But examining the same phenomena from past centuries is a more daunting task because relevant statistics are harder to come by.

Nearly 70 years after the launch of the first satellite‚ we still have more questions than answers about space. But a team of Berkeley researchers is on a mission to change this with a proposal to build a fleet of low-cost‚ autonomous spacecraft‚ each weighing only 10 grams and propelled by nothing more than the pressure of solar radiation. These miniaturized solar sails could potentially visit thousands of near-Earth asteroids and comets‚ capturing high-resolution images and collecting samples.

A collaborative research effort by Professor Hirohide Saito in the Department of Life Science Frontiers‚ CiRA‚ Kyoto University‚ and Professor Michiaki Hamada of Waseda University has developed the world's first deep generative model for RNA design. Their paper is published in the journal Nature Methods.

One way that cells communicate with one another is through the secretion and uptake of extracellular vesicles (EVs). EVs convey a multitude of cargoes‚ including proteins‚ lipids and nucleic acids. Their uptake affects the function of recipient cells by influencing signaling processes and gene expression.
