Record Carbon Dioxide Levels In 2012, Methane Off The Charts
2013-11-07 12:50:28

Alan McStravick for redOrbit.com - Your Universe Online If you are a fan of random violence occurring worldwide, a new report out this week is right up your alley. While we learned earlier this year that 2012 was the ninth warmest year since 1880, this week we were greeted with news that greenhouse gases, like carbon dioxide, methane and nitrous oxide, hit record highs in that same year. Specifically, carbon dioxide levels have increased a full 41 percent since the start of the...

Dwarfism In Mammals Also Occurred During Second Warming Period
2013-11-03 05:03:03

redOrbit Staff & Wire Reports - Your Universe Online While scientists have known for several years that some mammals became smaller during a period of warming known as the Paleocene-Eocene Thermal Maximum (PETM), researchers from the University of Michigan have found a second instance of mammalian “dwarfing” attributable to increasing temperatures. During the PETM, which occurred approximately 55 million years ago, mammals such as primates and groups that include deer and horses...

Sediments From The Deep Sea Give Insight Into Dynamics Of The Deep Biosphere
2013-10-22 14:53:38

Max Planck Institute Traces of past microbial life in sediments off the coast of Peru document how the microbial ecosystem under the seafloor has responded to climate change over hundreds of thousands of years. For more a decade scientists at the Max Planck Institute for Marine Microbiology and their colleagues at MARUM and the University of Aarhus have investigated microbial life from this habitat. This "Deep Biosphere", reaching several hundred meters below the seafloor, is exclusively...

Arctic Tunda May Add To Greenhouse Gas Emissions
2013-10-10 13:11:36

Brett Smith for redOrbit.com – Your Universe Online Arctic tundra is often thought of as a barren wasteland that has no direct bearing on global events. However, a team of Scandinavian scientists is warning that the tundra could be a significant contributor to greenhouse gas emissions if temperatures in the Arctic continue to rise. "The soil below the tundra contains very large quantities of carbon – more than twice as much as is present in the planet's entire atmosphere,”...

Methane Seeps Of The Deep Sea Are A Bacteria Feast For Lithodid Crabs
2013-10-08 09:54:33

Helmholtz Centre for Ocean Research Kiel (GEOMAR) Photos and analyses reveal more about a highly specialized food web The bottom of the deep sea is largely deserted. Oases occur for example at cold seeps where water transports dissolved elements from the seabed: Specialized microbes convert methane and sulfate from sea water to hydrogen sulfide releasing carbon dioxide. Highly adapted bacteria, many of which live in symbiosis with worms and clams, use the hydrogen sulfide for their...

Researchers Demonstrate Effective Recycling Of Radicals During Isoprene Degradation
2013-10-07 07:02:51

Forschungszentrum Juelich Hydroxyl (OH) radicals – known as the detergent of the atmosphere – decompose isoprene in the air. This leads to the creation of new OH radicals, which are then able to purify the air of other pollutants and trace gases. The scientific community had previously only been able to speculate about this mechanism. The atmosphere has an astonishing ability to cleanse itself. Chemical processes ensure that trace gases and pollutants are removed from the atmosphere...

Uranus' moon Umbriel -- Umbriel is a moon of Uranus discovered in 1851 by William Lassell. It was named after the 'dusky melancholy sprite' in Alexander Pope's The Rape of the Lock. Umbriel's surface is the darkest of the Uranian moons, and it is also the least geologically active. It is mostly composed of water ice, with the balance made up of silicate rock and methane ice. Most of its methane ice is on its surface. ----- Discovery Discovered by William Lassell...

Uranus' moon Ariel -- Ariel is a moon of Uranus discovered in 1851 by William Lassell. Its composition is roughly 50% water ice, 30% silicate rock, and 20% methane ice, and it appears to have regions of fresh frost in places. Largely devoid of impact craters, Ariel appears to have undergone a period of intense geological activity that has produced a huge network of fault canyons and liquid water outflows over its surface. ----- Discovery Discovered by William Lassell...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
