Saturn's largest moon, Titan, is an intriguing, alien world that's covered in a thick atmosphere with abundant methane. With an average surface temperature of a brisk -297 degrees Fahrenheit (about 90...
View ArticleChandra shows Milky Way is surrounded by halo of hot gas
(Phys.org)—Astronomers have used NASA's Chandra X-ray Observatory to find evidence our Milky Way Galaxy is embedded in an enormous halo of hot gas that extends for hundreds of thousands of light years....
View ArticleScientists developed a high-performance superconducting material by mixing...
(Phys.org)—Physicists describe how they have synthesized a new material that belongs to the iron-selenide class of superconductors, called LixFe2Se2(NH3)y, in a paper about to be published in EPJ B....
View ArticleSilver 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.
View ArticleNew 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...
View ArticleNASA 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...
View ArticleDetails of the 200lm/W TLED lighting technology breakthrough unraveled
Philips is the world's first to present a lamp prototype that produces a record 200 lumen per watt (lm/W) of high quality warm white light. This LED technology breakthrough brings energy-efficient LED...
View ArticleNASA's IRIS mission to launch in June
Lying just above the sun's surface is an enigmatic region of the solar atmosphere called the interface region. A relatively thin region, just 3,000 to 6,000 miles thick, it pulses with movement: Zones...
View ArticleMars water-ice clouds are key to odd thermal rhythm
(Phys.org) —Researchers using NASA's Mars Reconnaissance Orbiter have found that temperatures in the Martian atmosphere regularly rise and fall not just once each day, but twice.
View Article'Liquid-liquid' phase transition: Researchers identify transformation in...
(Phys.org) —Researchers at the University of Arkansas have identified that water, when chilled to a very low temperature, transforms into a new form of liquid.
View ArticleScientists identify major source of cells' defense against oxidative stress
Both radiation and many forms of chemotherapy try to kill tumors by causing oxidative stress in cancer cells. New research from USC on a protein that protects cancer and other cells from these stresses...
View ArticleSpace probes will be more useful with new amplifiers
Researchers at Chalmers have developed a new generation of amplifiers, which the European Space Agency (ESA) will be using throughout the world to receive signals from its space probes and satellites....
View ArticleNASA sees first Atlantic hurricane fizzling in cool waters
Chris may have been the Atlantic Ocean Hurricane Season's first hurricane, but didn't maintain that title for long. NASA satellite data revealed one good reason why Chris had weakened and became a...

Superconducting materials are widely used in the electrical instrumentation industry. European researchers made significant progress in enhancing superconductivity of a novel material currently the...
View ArticleAtoms at negative absolute temperature: The hottest systems in the world
(Phys.org)—In cold regions on earth, negative temperatures on the Fahrenheit or Celsius scale can often occur in winter; in physics, however, they were so far impossible. On the absolute temperature...
View ArticleLow 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....
View ArticleEnceladus' 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...
