Huge loops of plasma—superheated, charged gas—rise from an active region on the sun in a newly released picture from NASA’s Solar Dynamics Observatory. Each loop is as tall as several Earths stacked on top of each other.

Navigate the brain in a way that was never before possible; fly through major brain pathways, compare essential circuits, zoom into a region to explore the cells that comprise it, and the functions that depend on it.
The Human Connectome Project aims to provide an unparalleled compilation of neural data, an interface to graphically navigate this data and the opportunity to achieve never before realized conclusions about the living human brain.

Hydrogen bonding is a common “force” in nature, it’s what holds your DNA and proteins together and what makes water so weird and wonderful. Without it you wouldn’t be you, in fact you probably wouldn’t be anything. Hydrogen bonds are both inter and intra molecular forces in that it can act between different molecules (in the case of DNA bases) or within the same molecule (such as single chain proteins). Hydrogen bonding arises from polarity within a molecule, for this to happen a hydrogen must be bonded to an electronegative atom such as oxygen, fluorine or nitrogen (or be part of something like CHCl3). This causes the probability of an electron being around the hydrogen to decrease thus leaving it with a partial positive charge whilst the electronegative species has a slight negative charge. The slightly positive hydrogen is then attracted to other electronegative atoms that neighbor it. This causes an attractive force between them and gives an organized structure such as the crystalline form of ice or the hexagonal shape of a snowflake.

When microscopic marine organisms known as phytoplankton multiply into a dense population at the ocean’s surface, massive blooms can spread so far that they can only be seen from space. These algal blooms create beautiful patterns that can stretch for hundreds of miles and trace the ocean’s swirling currents.
NASA spacecraft detects ‘alien’ matter from beyond our solar system
The ‘interstellar material’ is the leftovers of older stars that have ended their lives in a supernova.
