Sinking of Seal Beach Wetlands Tied to Ancient Quakes

When geologists went in search for evidence of ancient tsunamis along Southern California’s coastal wetlands, they found something else. Their discoveries have implications for seismic hazard and risk assessment in coastal Southern California.

UNH Research Finds Pattern of Mammal Dwarfing During Global Warming

Mammalteethandchisel.jpg

More than 50 million years ago, when the Earth experienced a series of extreme global warming events, early mammals responded by shrinking in size. While this mammalian dwarfism has previously been linked to the largest of these events, research led by the University of New Hampshire has found that this evolutionary process can happen in smaller, so-called hyperthermals, indicating an important pattern that could help shape an understanding of underlying effects of current human-caused climate change.

"Going Deep" to Measure Earth’s Rotational Effects

Researchers in Italy hope to measure Earth’s rotation using a laser-based gyroscope housed deep underground, with enough experimental precision to reveal measurable effects of Einstein’s general theory of relativity. The ring laser gyroscope technology enabling these Earth-based measurements provide, unlike those made by referencing celestial objects, inertial rotation information, revealing fluctuations in the rotation rate from the grounded reference frame. The group discusses their work in this week’s Review of Scientific Instruments.

Hubble Dates Black Hole's Last Big Meal

STSCI-H-G1710a-1200x858.jpg

NASA's Hubble Space Telescope has found that the black hole at the center of our Milky Way galaxy ate its last big meal about 6 million years ago, when it consumed a large clump of infalling gas. After the meal, the engorged black hole burped out a colossal bubble of gas weighing the equivalent of millions of suns, which now billows above and below our galaxy's center.

Researchers Propose Technique for Measuring Weak or Nonexistent Magnetic Fields

Researchers at the University of Iowa have proposed a new approach to sampling materials with weak or no magnetic fields. The method could help advance research in a host of fields, from computing to MRI machines. The results were published in the journal “Physical Review Letters.”

Iron Dissolved by Air Pollution May Increase Ocean Potential to Trap Carbon

Iron particles generated by cities and industry are being dissolved by man-made air pollution and washed into the sea – potentially increasing the amount of greenhouse gases that the world’s oceans can absorb, a new study suggests.

Irvine, Calif., March 1, 2017 – The combination of prolonged hot spells with poor air quality greatly compounds the negative effects of each and can pose a major risk to human health, according to new research from the University of California, Irvine.“The weather factors that drive heat waves also contribute to intensified surface ozone and air pollution episodes,” said UCI professor of Earth system science Michael J.

The Heat Is On

NASA is developing a new family of flexible heat-shield systems with a woven carbon-fiber base material, and is using X-rays at Berkeley Lab's Advanced Light Source to test the designs.
