New rhythm for El Nino discovered

El Niño wreaks havoc across the globe, shifting weather patterns that spawn droughts in some regions and floods in others. The impacts of this tropical Pacific climate phenomenon are well known and documented.

Graphene joins the race to redefine the ampere

A new joint innovation by the National Physical Laboratory (NPL) and the University of Cambridge could pave the way for redefining the ampere in terms of fundamental constants of physics. The world's first graphene single-electron ...

Enceladus' jets reach all the way to its sea

Thanks to the Cassini mission we've known about the jets of icy brine spraying from the south pole of Saturn's moon Enceladus for about 8 years now, but this week it was revealed at the 44th Lunar and Planetary Science Conference ...

NASA Goddard lab works at extreme edge of cosmic ice

(Phys.org) —Behind locked doors, in a lab built like a bomb shelter, Perry Gerakines makes something ordinary yet truly alien: ice. This isn't the ice of snowflakes or ice cubes. No, this ice needs such intense cold and ...

Low density of Earth's core due to oxygen and silicon impurities

During accretion and differentiation of the Earth, chemical interactions in a silicate magma ocean and liquid iron drove silicon and oxygen impurities into what went on to become the liquid outer core. Contrasting with previous ...

New material for warm-white LEDs invented

Light emitting diodes, more commonly called LEDs, are known for their energy efficiency and durability, but the bluish, cold light of current white LEDs has precluded their widespread use for indoor lighting.

Silver sheds light on superconductor secrets

(Phys.org)—By doping a bismuth-based layered material with silver, Chinese scientists demonstrated that superconductivity is intrinsic to the new material rather than stemming from its impurities.
