Ancient shellfish remains rewrite 10,000-year history of El Niño cycles

The planet’s largest and most powerful driver of climate changes from one year to the next, the El Niño Southern Oscillation in the tropical Pacific Ocean, was widely thought to have been weaker in ancient times because of a different configuration of the Earth’s orbit. But scientists analyzing 25-foot piles of ancient shells have found that the El Niños 10,000 years ago were as strong and frequent as the ones we experience today. (more…)

UD study connects penguin chick weights to local weather conditions

Adélie penguins are an indigenous species of the West Antarctic Peninsula (WAP), one of the most rapidly warming areas on Earth. Since 1950, the average annual temperature in the Antarctic Peninsula has increased 2 degrees Celsius on average, and 6 degrees Celsius during winter. (more…)

Heritage of Earth’s water gives rise to hopes of life on other planets

A pioneering new study has shown that water found on Earth predates the formation of the sun – raising hopes that life could exist on exoplanets, the planets orbiting other stars in our galaxy.

The ground-breaking research set out to discover the origin of the water that was deposited on the Earth as it formed.

It found that a significant fraction of water found on Earth, and across our solar system, predates the formation of the sun. By showing that water is ‘inherited’ from the environment when a star is born, the international team of scientists believe other exoplanetary systems also had access to an abundance of water during their own formation.

The source of the sky’s X-ray glow

ANN ARBOR — In findings that help astrophysicists understand our corner of the galaxy, an international research team has shown that the soft X-ray glow blanketing the sky comes from both inside and outside the solar system.

The source of this “diffuse X-ray background” has been debated for the past 50 years. Does it originate from the solar wind colliding with interplanetary gases within our solar system? Or is it born further away, in the “local hot bubble” of gas that a supernova is believed to have left in our galactic neighborhood about 10 million years ago? (more…)

New View of Rainier’s Volcanic Plumbing

Electrical Images Show Upward Flow of Fluids to Magma Chamber

By measuring how fast Earth conducts electricity and seismic waves, a University of Utah researcher and colleagues made a detailed picture of Mount Rainier’s deep volcanic plumbing and partly molten rock that will erupt again someday.

“This is the most direct image yet capturing the melting process that feeds magma into a crustal reservoir that eventually is tapped for eruptions,” says geophysicist Phil Wannamaker, of the university’s Energy & Geoscience Institute and Department of Civil and Environmental Engineering. “But it does not provide any information on the timing of future eruptions from Mount Rainier or other Cascade Range volcanoes.” (more…)

Were Dinosaurs Cold-Blooded or Warm-Blooded? Neither, Study Finds

A study that originated in the lab of UA biologist Brian J. Enquist with UA alum John Grady suggests dinosaurs had a metabolism that was neither warm- nor cold-blooded, but somewhere in between.

Dinosaurs dominated the Earth for more than 100 million years, but all that remains today are bones. This has made it difficult to solve a long-standing and contentious puzzle: Were dinosaurs cold-blooded animals that lumbered along or swift warm-blooded creatures like those depicted in “Jurassic Park”?

Speeding at 1 Million mph, It Probes Black Hole and Dark Matter

A University of Utah-led team discovered a “hypervelocity star” that is the closest, second-brightest and among the largest of 20 found so far. Speeding at more than 1 million mph, the star may provide clues about the supermassive black hole at the center of our Milky Way and the halo of mysterious “dark matter” surrounding the galaxy, astronomers say.

Washington, D.C.—The Solar System has a new most-distant member, bringing its outer frontier into focus.

New work from Carnegie’s Scott Sheppard and Chadwick Trujillo of the Gemini Observatory reports the discovery of a distant dwarf planet, called 2012 VP113, which was found beyond the known edge of the Solar System. This is likely one of thousands of distant objects that are thought to form the so-called inner Oort cloud. What’s more, their work indicates the potential presence of an enormous planet, perhaps up to 10 times the size of Earth, not yet seen, but possibly influencing the orbit of 2012 VP113, as well as other inner Oort cloud objects.
