Ottawa researchers kill brain cancer in mice with combination immunotherapies

A promising combination of immunotherapies delivers a one-two punch to brain cancer tumours with high cure rates in mice, scientific evidence published in Nature Communications today says.

Canadian glaciers now major contributor to sea level change, UCI study shows

Ice loss from Canada’s Arctic glaciers has transformed them into a major contributor to sea level change, new research by University of California, Irvine glaciologists has found.

From 2005 to 2015, surface melt off ice caps and glaciers of the Queen Elizabeth Islands grew by an astonishing 900 percent, from an average of three gigatons to 30 gigatons per year, according to results published today in the journal Environmental Research Letters.

Bigger May Not Be Better When It Comes to Mississippi River Diversions

River diversions are a common coastal wetland restoration tool, but recent research, conducted by U.S. Geological Survey in collaboration with researchers in Louisiana State University’s Department of Civil and Environmental Engineering and the LSU AgCenter, has shown that large-scale Mississippi River diversions may significantly change water quality in estuaries, affecting economically important shellfish and fish species.

NOAA ship journeys into remote, deep Pacific ocean

Using the Deep Discoverer ROV, scientists will investigate deepwater habitats, geology, and the biology of sea animals as it dives as far as 3.7 miles (6,000 meters) deep. The public can watch online.

The 2017 explorations will run through September and are part of the third and final year of NOAA’s Campaign to Address Pacific monument Science, Technology, and Ocean NEeds, known as CAPSTONE, a major multiyear science initiative focusing on the deep ocean of U.S. marine protected areas in the central and western Pacific.

Eating Fish? Then You're Eating Plastic, Too

Synthetic fleece is something of a modern miracle. It keeps us warm and cozy, is easily cleaned and doesn’t even require we harm any animals to make it. Perfect, right? Well, every miracle comes with a price.

It turns out that every time we wash one fleece pullover or jacket, we’re sending about two grams of plastic microfibers out into our environment. Where those fibers end up from there is a bit concerning, because you’re probably eating them.

NASA Eyes the Heart of Tropical Cyclone Dineo on Valentine's Day

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

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

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

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

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.
