  Lincoln NE (SPX) Feb 01, 2019 Little life could endure the Earth-spanning cataclysm known as the Great Dying, but plants may have suffered its wrath long before many animal counterparts, says new research led by the University of Nebraska-Lincoln. About 252 million years ago, with the planet's continental crust mashed into the supercontinent called Pangaea, volcanoes in modern-day Siberia began erupting. Spewing carbon and methane into the atmosphere for roughly 2 million years, the eruption helped extinguish about 96 percent ... read more |

Mites, not a virus, are the main threat to bees, study findsWashington (UPI) Jan 30, 2019 Several studies have suggested parasitic mites both spread and worsen the effects of Deformed Wing Virus among honey bees. But new research shows the link between the two threats is tenuous. ... more 
A small fish provides insight into the genetic basis of evolutionBasel, Switzerland (SPX) Feb 01, 2019 Genetic analysis of sticklebacks shows that isolated populations in similar environments develop in comparable ways.

Using a familiar tool in a way it was never intended to be used opens up a whole new method to explore materials, report UConn researchers in Proceedings of the National Academies of Science. Their specific findings could someday create much more energy-efficient computer chips, but the new technique itself could open up new discoveries in a broad range of stuffs.

 Washington DC (SPX) Feb 01, 2019 
Planes flying over rain or snow can intensify the precipitation by as much as 10-fold, according to a new study.
The rain- and snow-bursts are not caused by emissions from the aircraft but are the peculiar consequence of the aircrafts' wings passing though clouds of supercooled water droplets in cloud layers above a layer of active rain or snow.
Under the right conditions, this effec ... more |

A gigantic cavity - two-thirds the area of Manhattan and almost 1,000 feet (300 meters) tall - growing at the bottom of Thwaites Glacier in West Antarctica is one of several disturbing discoveries reported in a new NASA-led study of the disintegrating glacier. The findings highlight the need for detailed observations of Antarctic glaciers' undersides in calculating how fast global sea levels wil ... more |

 Washington (UPI) Jan 30, 2019 
Several studies have suggested parasitic mites both spread and worsen the effects of Deformed Wing Virus among honey bees. But new research shows the link between the two threats is tenuous.
In a new study published in the Proceedings of the Royal Society B, scientists in Australia argue mites pose the greater threat to honey bee health. The virus, they say, is mostly an innocent bystan ... more |

 Kiel, Germany (SPX) Jan 29, 2019 
In recent decades, extratropical eruptions including Kasatochi (Alaska, USA, 2008) and Sarychev Peak (Russia, 2009) have injected sulfur into the lower stratosphere. The climatic forcing of these eruptions has however been weak and short-lived. So far, scientists have largely assumed this to be a reflection of a general rule; that extratropical eruptions lead to weaker forcing than their tropica ... more |

 Washington DC (SPX) Feb 01, 2019 
While Europe was in the early days of the Renaissance, there were empires in the Americas sustaining more than 60m people. But the first European contact in 1492 brought diseases to the Americas which devastated the native population and the resultant collapse of farming in the Americas was so significant that it may have even cooled the global climate.
The number of people living in North ... more |

 Munich, Germany (SPX) Jan 30, 2019 
Water levels in the Mekong basin, which extends through six countries in South-East Asia, are subject to considerable seasonal fluctuations. A new model now makes it possible to compute how water levels are impacted on various sections of the river by extreme weather events such as heavy rainfall or drought over extended periods.
To model the flow patterns of the river, with its complex ne ... more |

 University Park PA (SPX) Feb 01, 2019 
Membraneless assemblies of positively- and negatively-charged molecules can bring together RNA molecules in dense liquid droplets, allowing the RNAs to participate in fundamental chemical reactions. These assemblies, called "complex coacervates," also enhance the ability of some RNA molecules themselves to act as enzymes - molecules that drive chemical reactions. They do this by concentrating th ... more |

Polar vortexes. Hurricanes. Wildfires. With climate change making extreme weather events more frequent and intense, it is getting harder to keep the lights on and HVAC systems running.
As a power system researcher, I believe utilities need to get better at withstanding disasters and the disruption they cause. Investing more heavily is key, especially in infrastructure upgrades, renewable e ... more |

 Washington DC (SPX) Jan 29, 2019 
Russian scientists studied abandoned arable land in the European part of Russia where temperate forests grow. The study showed that trees start to grow on the abandoned fields immediately after the land has been withdrawn from agricultural use.
This finding contradicts the belief that trees appear on the fields only after grass that was approved earlier. As it turned out, the presence or a ... more |
