Europa has fascinated scientists for decades because it may harbor a vast ocean of liquid water beneath its frozen surface. This buried ocean makes Jupiter’s icy moons one of the solar system’s most promising locations for investigating whether conditions suitable for life exist beyond Earth. But new research led by Rutgers University scientist Rugendra Ojha shows that getting materials from Europa’s deep oceans may be much more difficult than previously thought. Testing potential routes through Europa’s ice In a study published in natural astronomyOjha and his colleagues used computer simulations to examine whether water from Europa’s global ocean could migrate…

Matt Long stood before the Granbury City Council at its April city planning meeting and opposed the influx of data centers planned for Hood County, likening them to spiritual abominations. “We consider ourselves a Christian city within a Christian county,” said Long, a member of the county’s Development Commission who lives near Granbury. “As a Christian, do you think trading 2,100 acres of natural beauty for a godless technological complex brings you closer to creation,…

Earth’s hidden “golden kitchen” may be operating far beneath the ocean floor. Island arcs are series of volcanoes that develop above subduction zones where one oceanic plate subducts beneath another, and are often unusually rich in gold. Scientists have long debated why these regions become so rich. A new study led by Dr. Christian Timm, a marine geologist at the GEOMAR Kiel-Helmholtz Center for Marine Research, provides a deeper explanation. “Our study shows that the melting hydrous mantle beneath the island arc is the primary driver of gold enrichment,” Tim says. “In these environments, the mantle behaves like a multi-stage…

On a recent summer day, rain poured down outside climatologist David Easterling’s Hendersonville home. He made his way through the garage to the back door.”This is a standard 4-inch rain gauge. You can buy it, but it’s semi-official,” Easterling said as he stepped out onto the wooden deck to explain. There, a plastic jug-like device was collecting water droplets.It’s a warm July afternoon. Rain from this storm is barely covering the bottom of the gauge. Almost two years ago, Hurricane Helen brought unprecedented destruction to Western North Carolina. At that point Helen’s rainfall was nearly filling the gauge.”I measured it…

The Trump administration appears to be doing everything it can to give the coal industry everything it wants. These efforts may not succeed, but unless legal challenges force a change in direction, they could keep a dying industry on life support and pass on the economic and environmental costs of doing so to the American people. The National Coal Council, an advisory group that includes executives from coal mining companies and major U.S. power companies, met with Trump administration officials last week and laid out the following policy: 19 Recommendations. One of its key demands is for the government to…

Rising temperatures often disrupt sleep. Hot nights can make it difficult to fall asleep and cause you to wake up more often during the night, making you less rested the next day. One reason for this is thermoregulation, the body’s ability to maintain internal temperature within a safe range. Sleep is closely related to body temperature. In order to fall asleep and stay asleep, your body typically needs to lose some heat. This becomes difficult when the bedroom is hot. And British summers are getting hotter. The Met Office reports that the chance of temperatures exceeding 40C in the UK…

Comparisons across ages from 15 to 90 call into question the persistent belief that adult personality remains largely fixed. Research: Personality traits are not as stable as people think. Image credit: Ribkhan / Shutterstock In a recent study published online as a “press article” in the journal communication psychologyResearchers compared changes in personality traits to changes in other aspects of life. Historically, personality traits have been thought to be largely stable and unchanging once a person reaches adulthood. Previous research suggests that personality traits develop throughout the lifespan, and provides promising initial evidence that personality traits can be modified through…

Researchers looked at how diet, sleep, physical activity, and television viewing were related to school performance, while taking into account demographic factors and neurodevelopmental disorders. Research: Independent and combined associations of lifestyle behaviors on academic achievement in adolescents. Image credit: Pixel-Shot / Shutterstock In a recent study published online as a “press article” in the journal scientific reportA group of Spanish researchers investigated the independent and combined associations between physical activity, sleep, diet, television viewing, and academic performance in adolescents, taking into account demographic factors and neurodevelopmental disorders (NDs). background Is it possible that daily habits such as eating well,…

A vast reservoir of magma beneath Japan’s Kikai caldera appears to be filling up again, giving scientists a glimpse of how some of Earth’s largest volcanoes recover after devastating eruptions. The discovery, led by researchers at Kobe University, could improve our understanding of giant caldera systems such as Yellowstone in the United States and Toba in Indonesia. It could also help scientists identify subsurface changes that precede future mega-eruptions. Volcano capable of huge eruptions Mt. Kikai is a largely submerged volcanic caldera in the south of Japan. About 7,300 years ago, the largest known volcanic eruption of the Holocene, the…

By examining six regions of the brain at single-molecule resolution, researchers identified layers of tau pathology that were not fully captured by traditional tissue staining. Research: Nanoscale tau aggregates in Parkinson’s disease. Image credit: Peterschreiber.media / Shutterstock In a recent study published online as a “press article” in the journal npj parkinson’s diseaseresearchers used single-molecule pull-down (SiMPull) assays and super-resolution microscopy to map the nanoscale distribution of protein aggregates in postmortem human brain tissue. In this study, we specifically analyzed six different brain regions using tissue from 29 postmortem donors, where sample availability varied by region, and identified distinct populations…
