The Arctic is burning in a whole new way
A network of salty ponds may be gurgling beneath Mars’ South Pole alongside a large underground lake, raising the prospect of tiny, swimming Martian life. In the latest study appearing in the journal Nature Astronomy, the scientists provide further evidence of this salty underground lake, estimated to be 12 miles to 18 miles (20 kilometers to 30 kilometers) across and buried 1 mile (1.5...
Biodiversity and plant decomposition should be factored into climate models, study finds
"Zombie fires" and burning of fire-resistant vegetation are new features driving Arctic fires—with strong consequences for the global climate—warn international fire scientists in a commentary published in Nature Geoscience.
Borate-based passivation layers enables reversible calcium batteries
The afterlife of plant matter plays a significant role in ecosystems, as a key processor and provider of key nutrients. The rate of decomposition for leaf litter, among other plant matter, heavily influences the health of animals and plants, and this rate is expected to significantly increase as Earth continues to warm. There is another factor that could hold impact these ecosystems even more than...
NASA casts an infrared eye on Tropical Storm Kujira's very cold cloud tops
A study published in the journal Energy and Environmental Science has combined experimental and theoretical approaches to study the passivation layers formed on calcium metal electrodes and their influence on the reversible operation of calcium-based batteries. The work is led by researchers from the ICMAB-CSIC, who have collaborated with the ALBA Synchrotron (MIRAS beamline) as well as with other...
New study may revise a 60-year-old theory about flowing viscous liquids
NASA analyzed the cloud top temperatures in Tropical Storm Kujira using infrared light to determine the strength of the storm. Infrared imagery revealed that the strongest storms were around Kujira's center and in a band of thunderstorms on the western side of the storm.
Spinal cord stimulation reduces pain and motor symptoms in Parkinson's disease patients
The international collaborative team of Tokyo University of Agriculture and Technology (TUAT) in Japan, Indian Institute of Technology Ropar (IIT Ropar) in India, and Osaka University in Japan has discovered for the first time a topological change of viscous fingering (one of classical interfacial hydrodynamics), which is driven by "a partially miscibility," where the two liquids do not mix...

Artificial intelligence can help protect orchids and other species
Early results of an experimental vaping study have shown significant lung injury from e-cigarette devices with nickel-chromium alloy heating elements.
Pandemic sets off future wave of worsening mental health issues
Many orchid species are threatened by land conversion and illegal harvesting. However, only a fraction of those species is included in the IUCN Red List of Threatened Species, because assessments require a lot of time, resources and expertise. A new approach, an automated assessment developed under the lead of biodiversity researchers from Central Germany, now shows that almost 30% of all orchid...

The mysterious luminescence phenomena of earthquake lightning
Neuronal communication is so fast, and at such a small scale, that it is exceedingly difficult to explain precisely how it occurs. An observation enabled by a custom imaging system, has led to a clear understanding of how neurons communicate with each other by modulating the 'tone' of their signal, which previously had eluded the field.
New Mars rover is ready for space lasers
Were you aware that earthquakes are sometimes associated with luminescence, called earthquake lightning? This phenomenon had been documented throughout history, such as between 1965 and 1967, the Matsushiro earthquake swarm caused the surrounding mountain to flicker with light multiple times. In 1993 when an earthquake caused a tsunami off the coast in Southwest Hokkaido which caused 5 boats...
Anti-convulsant drug can modify DNA conformation and interact with chromosome proteins
When the Apollo astronauts landed on the Moon, they brought devices with them called retroreflectors, which are essentially small arrays of mirrors. The plan was for scientists on Earth to aim lasers at them and calculate the time it took for the beams to return. This provided exceptionally precise measurements of the Moon's orbit and shape, including how it changed slightly based on Earth's...
Ancient Adelie penguin colony revealed by snowmelt at Cape Irizar, Ross Sea, Antarctica
Results of recent studies involving valproic acid, used for decades as an anti-convulsant drug, show that it can interact with the conformation of DNA and regulate gene expression.
Despite high hopes, carbon absorbed by Amazon forest recovery is dwarfed by deforestation emissions
Researcher Steven Emslie encountered a puzzle at Cape Irizar, a rocky cape located just south of the Drygalski Ice Tongue on the Scott Coast, Ross Sea. He found both ancient and what appeared to be fresh remains of Adelie penguins, mostly of chicks, which frequently die and accumulate at these colonies. However, the "fresh" remains were puzzling, he says, because there are no records of an active...
Understanding oxygen-reducing enzymes
Regrowing forests are absorbing just a small proportion of the carbon dioxide released from widespread deforestation in the Amazon, according to new evidence.
Boosting public trust in scientists hangs on communications methods
Methane is a powerful greenhouse gas that plays a central role in the global carbon cycle. At the same time, it is an important energy source for us humans. About half of its annual production is made by microorganisms known as methanogens that decompose organic material such as dead plants. This normally takes place in a habitat without oxygen as this gas is lethal to methanogens. But even in...
New study finds novel functions of the pyruvate-sensing protein PdhR in E. coli
While debate over COVID-19 guidelines and vaccine development has raised skeptics' eyebrows and undermined confidence, a West Virginia University associate professor says that communication is essential for the science community to gain the American public's trust. According to Geah Pressgrove, scientists and communications professionals need to rethink how they communicate through four distinct...
Study describes discovery of close binary trans-Neptunian object
Organisms, ranging from bacteria to humans, run on an interconnected series of metabolic pathways—with glycolysis being the essential process that generates energy from sugars (glucose) in food. Pyruvate is the final product of glycolysis: It is an important molecule that acts as a node between different pathways. To better understand how these pathways work, a team of scientists, led by Dr....
