• One-pot technique creates structures with potential for more efficient manufacturing and energy storage

  26-01-2017 23:08
  
  To create more efficient catalysts, sensing and separation membrane, and energy storage devices, scientists often start with particles containing tiny pore channels. Defects between the particles can hamper performance. At Pacific Northwest National Laboratory, a team created a one-pot method that produces complex, well-structured microscopic pyramids. This approach offers control over three-dimensional material growth similar to that seen in nature, a vital benchmark for material synthesis.

  Researchers have shown that looking at movements of operators and vehicles between farms in the same way we look at contacts in social networks can help explain the spread of dangerous infectious diseases of livestock, such as foot-and-mouth disease and avian influenza. This research, published in PLOS Computational Biology, can contribute to the development of more accurate tools for predicting the spread of livestock diseases and may help implement more effective biosecurity measures in farms.

• Earth's orbital variations and sea ice synch glacial periods

  26-01-2017 19:10
  
  Earth is currently in what climatologists call an interglacial period, a warm pulse between long, cold ice ages when glaciers dominate our planet's higher latitudes. For the past million years, these glacial-interglacial cycles have repeated roughly on a 100,000-year cycle. Now a team of Brown University researchers has a new explanation for that timing and why the cycle was different before a million years ago.

• Physicists unveil new form of matter—time crystals

  26-01-2017 18:41
  
  Normal crystals, likes diamond, are an atomic lattice that repeats in space, but physicists recently suggested making materials that repeat in time. Last year, UC Berkeley's Norman Yao sketched out the phases surrounding a time crystal and what to measure in order to confirm that this new material is actually a stable phase of matter. This stimulated two teams to build a time crystal, the first examples of a non-equilibrium form of matter.

  NASA calculated California's rainfall over seven days using a constellation of satellites and created a map to provide the visual extent of the large rainfall totals. It is sunny in southern California today but recent unusually heavy rainfall led to rock slides, mudslides and flooding in that part of the country. Rainfall of almost 4 inches (101.6 mm) in one day was reported in Long Beach, California. Some highways in the area were flooded due to intense downpours.

  The dynamic space environment that surrounds Earth - the space our astronauts and spacecraft travel through - can be rattled by huge solar eruptions from the sun, which spew giant clouds of magnetic energy and plasma, a hot gas of electrically charged particles, out into space. The magnetic field of these solar eruptions are difficult to predict and can interact with Earth's magnetic fields, causing space weather effects.
