An exciting and profoundly consequential endeavor of neuroscience that may be realized this century is the complete mapping of the human brain – the connectome. However, just like the mapping of the human genome, the usefulness of such data is
Helicity is a measure of cork-screw-like motion described by the amount of twisting, writhing, and linking in a fluid. Total helicity is conserved for ideal fluids, but how helicity changes in real fluids with even tiny amounts of viscosity has
Genes make proteins, and specific sets of proteins define tissue-type: for instance, you wouldn’t expect to find proteins for hemoglobin in neuronal cells and conversely you wouldn’t expect to find proteins that make voltage-gated ion channels in red blood cells.
Several new observations suggest that primordial black holes, which are often viewed as speculative or hypothetical objects, are responsible for several unexplained and mysterious cosmic phenomena. Observations of deep space quasars – extremely luminous objects with highly active supermassive black
The cosmological principle has encountered discrepancies in observational data that throw its basic assumptions into question – observations that suggest possible anisotropy, or preferred orientation, as well as inhomogeneity at large-scales.
The future of transportation may have come one step closer -- the near-supersonic rail system known as hyperloop has passed another key milestone on its path to become reality, the US startup Hyperloop One recently announced

How do grains of sand or rice pack together – and how does this effect their mechanical properties and behavior? For example, when sand is packed together it behaves like a solid, whereas when it is loose, it behaves like
Washington State University physicists have found a way to write an electrical circuit into a crystal, opening up the possibility of transparent, three-dimensional electronics that, like an Etch A Sketch, can be erased and reconfigured.

Saturn's huge moon Titan harbors yet another possible key ingredient for life, a new study reports.Titan's thick atmosphere contains large quantities of vinyl cyanide molecules, which could conceivably form membranes around cells in the liquid-hydrocarbon seas that dot the frigid moon's surface, according to
Using the W.M. Keck observatory in Hawaii, astronomers led by Christina Eilers have discovered extremely young quasars with a puzzling property: these quasars have the mass of about a billion suns, yet have been collecting matter for less than 100,000
