NASA Eyes the Heart of Tropical Cyclone Dineo on Valentine's Day
February 14, 2017 03:57 PM - Rob Gutro
On Feb. 14, 2017 at 2:45 a.m. EST (0745 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite captured a visible image Dineo that showed strong thunderstorms wrapping into and around the "heart" or center of the storm's low-level circulation. A thick band of powerful thunderstorms from the eastern quadrant wrapped south and west into the center.
Long-lasting flow battery could run for more than a decade with minimum upkeep
February 14, 2017 03:44 PM - Harvard John A. Paulson School of Engineering and Applied Sciences
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new flow battery that stores energy in organic molecules dissolved in neutral pH water. This new chemistry allows for a non-toxic, non-corrosive battery with an exceptionally long lifetime and offers the potential to significantly decrease the costs of production.
Ancient Jars Found in Judea Reveal Earth's Magnetic Field is Fluctuating, Not Diminishing
February 14, 2017 03:21 PM - American Friends of Tel Aviv University
Albert Einstein considered the origin of the Earth's magnetic field one of the five most important unsolved problems in physics. The weakening of the geomagnetic field, which extends from the planet's core into outer space and was first recorded 180 years ago, has raised concern by some for the welfare of the biosphere.
The Most Remote Place on Earth is Also One of the Most Polluted
February 14, 2017 03:17 PM - Yale Environment 360
Scientists have discovered high levels of extremely toxic chemicals in the most remote place on earth — the 36,000-foot-deep Mariana Trench in the western Pacific Ocean, according to new research published in the journal Natural Ecology and Evolution.
Marine biologists used fish traps and robotic submarines to collect crustaceans from the trench’s seafloor and then measured the level of persistent organic pollutants (POPs) in each specimen.
Sunlight or bacteria? Scientists investigate what breaks down permafrost carbon
February 14, 2017 02:01 PM - Kathleen Haughney via Florida State University
A Florida State University researcher is delving into the complexities of exactly how permafrost thawing in the Earth’s most northern regions is cycling back into the atmosphere as carbon dioxide and further fueling climate change.
Answer: It has a lot to do with tiny little bugs called microbes and little to do with sunlight.
Assistant Professor of Earth, Ocean and Atmospheric Science Robert Spencer and a team of researchers traveled to Siberia from 2012 to 2015 to better understand how thawing permafrost affected the carbon cycle. They specifically investigated how the vast amounts of carbon stored in this permafrost transferred to the atmosphere as carbon dioxide.
El Niño resulted in unprecedented erosion of the Pacific coastline, according to research

Last winter’s El Niño might have felt weak to residents of Southern California, but it was in fact one of the most powerful climate events of the past 145 years.
Study prompts rethink on fighting infections
February 14, 2017 11:06 AM - The University of Edinburgh
Fresh insights into how immune cells are regulated could signal a new approach to tackling infections.
Important to maintain a diversity of habitats in the sea
February 14, 2017 10:58 AM - University of Gothenburg
Researchers from University of Gothenburg and the Swedish University of Agricultural Sciences (SLU) show that both species diversity and habitat diversity are critical to understand the functioning of ecosystems.
Genes in albino orchids may hold clues to parasitic mechanism used by non-photosynthetic plants
February 14, 2017 10:49 AM - Kobe University
How do plants give up photosynthesis and become parasites? A research team in Japan are using comprehensive analysis of gene expression in albino and green orchids to investigate the evolution of parasitic plant.
SFU technology puts 'touch' into long-distance relationships
February 14, 2017 10:46 AM - Simon Fraser University
Long-distance couples can share a walk, watch movies together, and even give each other a massage, using new technologies being developed in Carman Neustaedter’s Simon Fraser University lab.
