Ever smaller, ever faster, ever cheaper - since the start of the computer age the performance of processors has doubled on average every 18 months. 50 years ago already, Intel co-founder Gordon E. Moore prognosticated this astonishing growth in performance. And Moore's law seems to hold true to this day.

For the first time, scientists have observed ripples in the fabric of spacetime called gravitational waves, arriving at the earth from a cataclysmic event in the distant universe. This confirms a major prediction of Albert Einstein's 1915 general theory of relativity and opens an unprecedented new window onto the cosmos.

Silent since its last call to mothership Rosetta seven months ago, the Philae lander is facing conditions on Comet 67P/Churyumov–Gerasimenko from which it is unlikely to recover.

These surprising results could in many cases make the search for better crystals obsolete and fundamentally change the way scientists study the complex biological machinery involved in photosynthesis, catalysis and many other important processes in living things. A better understanding of these processes could drive innovation in a number of areas, from clean energy production to drug development.

New measurements from a NASA satellite have allowed researchers to identify and quantify, for the first time, how climate-driven increases of liquid water storage on land have affected the rate of sea level rise.

A newly formed star lights up the surrounding cosmic clouds in this new image from ESO’s La Silla Observatory in Chile. Dust particles in the vast clouds that surround the star HD 97300 diffuse its light, like a car headlight in enveloping fog, and create the reflection nebula IC 2631. Although HD 97300 is in the spotlight for now, the very dust that makes it so hard to miss heralds the birth of additional, potentially scene-stealing, future stars.

In a new study, Hao Yan, director of the Center for Molecular Design and Biomimetics at Arizona State University's Biodesign Institute presents a clever means of localizing and confining enzymes and the substrate molecules they bind with, speeding up reactions essential for life processes.

Researchers in Japan and France artificially created such unique 1D nano electronic systems on the surface of a solid, and observed the 1D electronic state (energy and kinetic momentum of electrons) by analyzing photo-emitted electrons from the sample, and verified the electronic structure. This group's research will help elucidate the mystery of unique electronic properties of 1D nano metals and provide, for example, information helpful for the prediction of electrons confined in extremely fine metal nanowires used in next-generation semiconductor devices.

New, detailed maps of the world's natural landscapes created using NASA satellite data could help scientists better predict the impacts of future climate change.

Phagosomes carried by the Motors initially move in a back-and-forth manner near the cell periphery, and mature by fusing with other compartments. As time passes, there is a switch that causes the phagosomes to move in an almost unidirectional manner towards the cell centre. Here, they fuse with acidic lysosomes so that the pathogen can be degraded.
