NASA Video Reveals the Difference Between Solar Flares and CMEs

NASA Video Shows the Difference Between Flares and CMEs

This short NASA video highlights the differences between coronal mass ejections (CMEs) and solar flares. How do you tell the difference between a flare and a CME in NASA images? Flares look like bright flashes of light on the sun. Coronal mass ejections look like clouds zooming out into space. Image Credit: NASA/SDO/ESA/SOHO/Nune There are […]

Possibility of El Niño Event in 2014 is Fading

Prospect of 2014 El Nino

Climatologists believe the latest Kelvin waves are the “last hurrah” for a much-hoped-for El Niño event in 2014. Prospects have been fading for an El Niño event in 2014, but now there’s a glimmer of hope for a very modest comeback. Scientists warn that unless these developing weak-to-modest El Niño conditions strengthen, the drought-stricken American […]

New Model Demonstrates That Stars Can Absorb Gravitational Ripples

New Model Demonstrates That Stars Can Absorb Gravitational Ripples

A newly published study contradicts previous assumptions about the behavior of gravitational waves, demonstrating that stars can absorb the energy of gravitational waves. Scientists have shown how gravitational waves—invisible ripples in the fabric of space and time that propagate through the universe—might be “seen” by looking at the stars. The new model proposes that a […]

Salk Institute Discovers an On/Off Switch for Aging Cells

Salk Institute Discovers an On Off Switch for Aging Cells

Researchers at the Salk Institute for Biological Studies have discovered an on-and-off “switch” in cells that may hold the key to healthy aging. In our bodies, newly divided cells constantly replenish lungs, skin, liver and other organs. However, most human cells cannot divide indefinitely–with each division, a cellular timekeeper at the ends of chromosomes shortens. […]

UNIGE Physicists Teleport Quantum State of a Photon to a Crystal

Physicists Teleport Quantum State of a Photon to a Crystal Over 25 Kilometers of Fiber

Quantum physicists have teleported the quantum state of a photon to a crystal over 25 kilometers of optical fiber, smashing the previous record of 6 kilometers. Physicists at the University of Geneva (UNIGE) have succeeded in teleporting the quantum state of a photon to a crystal over 25 kilometers of optical fiber. The experiment, carried […]

New Formula Improves Liquid Battery Technology

New Formula Leads to Improved Liquid Battery

MIT engineers have developed an improved liquid battery system that could enable renewable energy sources to compete with conventional power plants. Extensive testing has shown that even after 10 years of daily charging and discharging, the system should retain about 85 percent of its initial efficiency. Donald Sadoway and colleagues have already started a company […]

MAVEN Spacecraft Successfully Enters Mars’ Orbit

Animation Shows MAVEN Orbiting Mars

After a 10-month journey, NASA has confirmed that the MAVEN spacecraft has successfully entered Mars’ orbit. NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft successfully entered Mars’ orbit at 10:24 p.m. EDT Sunday, September 21, where it now will prepare to study the Red Planet’s upper atmosphere as never done before. MAVEN is the first […]

Yale Study Shows Estrogen Helps Calm Stressed Cells

Yale Study Shows Estrogen Helps Calm Stressed Cells

New research from Yale University shows that the hormone estrogen helps cells survive stress, fueling speculation that anti-estrogen therapy may help kill cancer cells and prolong the survival of patients. Stress is as bad for cells as it is for people, but scientists have had a hard time devising ways to study its effects on […]

New Hubblecast Video Explores the South Atlantic Anomaly

Hubblecast 77 Video Hubble and the Bermuda Triangle of Space

This newly released six minute video details the mysterious region known as the South Atlantic Anomaly – an area where the Earth’s inner Van Allen radiation belt comes close to the Earth’s surface, increasing the flux of energetic particles and exposes orbiting satellites to higher-than-usual levels of radiation. Hubblecast 77: Hubble and the Bermuda Triangle […]

Hubble Views Spiral Galaxy NGC 7793

Hubble Image of Spiral Galaxy NGC 7793

This newly released Hubble image shows spiral galaxy NGC 7793. This new image from the NASA/ESA Hubble Space Telescope shows NGC 7793, a spiral galaxy in the constellation of Sculptor some 13 million light-years away from Earth. NGC 7793 is one of the brightest galaxies in the Sculptor Group, and one of the closest groups […]

Phase-Change Materials Increase the Speed Limit for Computers

Phase Change Materials Increase the Speed Limit for Computers

By replacing silicon with phase-change materials, new research shows that computers could be capable of processing information up to 1,000 times faster than currently models. The present size and speed limitations of computer processors and memory could be overcome by replacing silicon with ‘phase-change materials’ (PCMs), which are capable of reversibly switching between two structural […]

New Graphene Sensor Detects Cancer Biomarkers

New Sensor Tracks Down Cancer Biomarkers

Scientists from the University of Swansea have developed an ultrasensitive graphene biosensor that can detect molecules that indicate an increased risk of developing cancer. The biosensor has been shown to be more than five times more sensitive than bioassay tests currently in use, and was able to provide results in a matter of minutes, opening […]
