Research Shows Volcanism and Greenhouse Gas Could Have Warmed Mars

Research Shows Warmth and Flowing Water on Early Mars

New research from Brown University and Israel’s Weizmann Institute of Science shows that warmth and water flow on ancient Mars were probably episodic, related to brief periods of volcanic activity that spewed tons of greenhouse-inducing sulfur dioxide gas into the atmosphere. Providence, Rhode Island (Brown University) — Ample evidence of ancient rivers, streams, and lakes […]

A Spiral in a Furnace – Barred Spiral Galaxy NGC 986

New Hubble Image of Barred Spiral Galaxy NGC 986

This newly released Hubble image shows barred spiral galaxy NGC 986, which is located about 56 million light-years away. This new Hubble image is a snapshot of NGC 986 — a barred spiral galaxy discovered in 1828 by James Dunlop. This close-up view of the galaxy was captured by Hubble’s Wide Field and Planetary Camera […]

New Clues About Hidden the Interior of Uranus Revealed

Clues About Hidden Interior of Uranus Revealed

Using images NASA’s Voyager-2, astronomer Erich Karkoschka has uncovered features in Uranus’ atmosphere that reveal an unexpected, strange rotation pattern and point to the possible existence of an unusual feature inside the planet’s interior. The findings shed light on the interior structures of giant gas planets, not only of Uranus, a planet for which observational […]

2014 – The Highest Global Mean Sea Surface Temperatures Ever Recorded

New Research Shows Warmest Oceans Ever

New data reveal the highest global mean sea surface temperatures ever recorded, indicating that the 14-year-long pause in ocean warming has come to an end. “This summer has seen the highest global mean sea surface temperatures ever recorded since their systematic measuring started. Temperatures even exceed those of the record-breaking 1998 El Niño year,” says […]

A Strong Magnetic Field Shaped the Early Solar System

Study Finds That a Strong Magnetic Field Shaped the Early Solar System

New research reveals the first experimental evidence that our solar system’s protoplanetary disk was shaped by an intense magnetic field that drove a massive amount of gas into the sun within just a few million years. Infant planetary systems are usually nothing more than swirling disks of gas and dust. Over the course of a […]

American Obesity Costs the Nation Billions in Lost Productivity

Obesity Costs the USA Billions in Lost Productivity

A new study from Yale University provides state-level estimates of obesity-attributable costs of absenteeism among working adults in the United States, finding that the total national loss in productivity because of obesity-related absenteeism is roughly $8.65 billion per year. Obesity is associated with significant increases in absenteeism among American workers and costs the nation over […]

Massive Compact Galaxies with Star-Driven High-Velocity Outflows

Astronomers Discover Massive Compact Galaxies with High-Velocity Outflows

Astronomers investigate the process of rapid star formation in 12 massive galaxies that host high-velocity ionized gas outflows, finding that these fast outflows are most likely driven by feedback from star formation rather than active galactic nuclei (AGN). Researchers using NASA’s Hubble Space Telescope and Chandra X-ray Observatory have uncovered young, massive, compact galaxies whose […]

NASA Telescopes Reveal That Sagittarius A* May Be Producing Neutrinos

Telescopes Reveal That a Black Hole May Be a Neutrino Factory

Using three NASA satellites, astronomers have revealed the first evidence that the Milky Way’s supermassive black hole (Sagittarius A*) may be producing neutrinos. The giant black hole at the center of the Milky Way may be producing mysterious particles called neutrinos. If confirmed, this would be the first time that scientists have traced neutrinos back […]

Physicists Demonstrate Control of a Two-Qubit System

UCSB Physicists Detail a Piece of the Quantum Puzzle

In a newly published study, UCSB physicists demonstrate the high level of controllability needed to explore ideas in quantum simulations. While the Martinis Lab at UC Santa Barbara has been focusing on quantum computation, former postdoctoral fellow Pedram Roushan and several colleagues have been exploring qubits (quantum bits) for quantum simulation on a smaller scale. […]

New Theory Suggests Quantum Effects Caused by Interacting Parallel Worlds

Quantum Weirdness Caused by Interacting Parallel Worlds

A new theory of quantum mechanics presumes not only that parallel worlds exist, but also that their mutual interaction is what gives rise to all quantum effects observed in nature. The theory, first published by Professor Bill Poirier four years ago, has recently attracted attention from the foundational physics community, leading to an invited Commentary […]

Jupiter’s Red Spot – A Product of Simple Chemicals Being Broken Apart by Sunlight

Red Spot on Jupiter is Likely a Sunburn

New data from NASA’s Cassini mission reveal that the color of Jupiter’s Great Red Spot is likely a product of simple chemicals being broken apart by sunlight in the planet’s upper atmosphere, contradicting the other leading theory for the origin of the spot’s striking color — that the reddish chemicals come from beneath Jupiter’s clouds. […]

The Rapid-Fire Evolution of Green Anoles

Native Lizards Show Rapid Fire Evolution

A newly published study from Harvard University found that in just 20 generations in 15 years green anoles evolved larger toe pads equipped with more sticky scales to allow for better climbing. Though it’s often portrayed as a process that takes place over thousands of years, under the right circumstances the evolution of enhanced traits […]
