Wastewater cleaned thanks to a new adsorbent material made from fruit peels

Researchers from the University of Granada (UGR), and from the Center for Electrochemical Research and Technological Development (Centro de Investigación y Desarrollo Tecnológico en Electroquímica, CIDETEQ) and the Center of Engineering and Industrial Development (Centro de Ingeniería y Desarrollo Industrial, CIDESI), both in Mexico, have developed a process that allows to clean waters containing heavy metals and organic compounds considered pollutants, using a new adsorbent material made from the peels of fruits such as oranges and grapefruits.

Climate Change and an "Overlooked" Nutrient: Silica

Among ecologists, carbon gets all the glory. Scientists examine its critical role in plant growth and decay, they chart its contributions to greenhouse gases, and they measure its sequestration in earth, sea, and sky.

Often overlooked in all this research is the humble element silicon, or “silica,” as it’s called when found in nature. If ecologists (or biologists or biogeochemists) think of silica at all, they regard it as a bit player, a ho-hum component of rocks and sand.

Chicken immune system 'too slow' to beat Campylobacter

New University of Liverpool research reveals that the immune response of farmed chickens does not develop fast enough to fight off Campylobacter during their short lifespan. The findings have important implications in the challenge towards developing a poultry vaccine for the bug, which is the UK’s leading cause of food poisoning.

Fish evolve by playing it safe

New research supports the creation of more marine reserves in the world’s oceans because, the authors say, fish can evolve to be more cautious and stay away from fishing nets.

Astronomers Don't Point This Telescope—The Telescope Points Them

The hills of West Texas rise in waves around the Hobby-Eberly Telescope, a powerful instrument encased in a dome that looks like the Epcot ball. Soon, it will become more powerful still: Scientists recently primed the telescope to find evidence of dark energy in the early universe, prying open its eye so it can see and process a wide swath of sky. On April 8, scientists will dedicate the new telescope, capping off the $40 million upgrade and beginning the real work.

Global CO2 Levels Stay Flat for a Third Year

Data shows that global CO2 emissions have remained roughly the same for the third year in a row. Although that’s good news for the fight against climate change, it’s important to put this data in perspective. 

World Meteorological Day celebrates importance of clouds for weather, climate and water

Clouds inspire art and thought, but few natural phenomena are as important to weather, climate or water, the United Nations meteorological agency today said, launching a digital cloud atlas to celebrate World Meteorological Day.

Northern Lights: Large-Scale Solar Power is Spreading Across the U.S.

Once largely confined to the sunny Southwest, utility-scale solar power plants are now being built everywhere from Minnesota to Alabama to Maine. Aided by plunging costs and improving technologies, these facilities are expected to provide a big boost to U.S. solar energy production.

University of Toronto explores how urban agriculture intersects with social justice

As Toronto continues to grow, urban agriculture may play a more significant role for people seeking alternative sources of nutritious and affordable food, U of T researcher Colleen Hammelman says.  

New Study Maps Space Dust in 3-D

Consider that the Earth is just a giant cosmic dust bunny—a big bundle of debris amassed from exploded stars. We Earthlings are essentially just little clumps of stardust, too, albeit with very complex chemistry.

And because outer space is a very dusty place, that makes things very difficult for astronomers and astrophysicists who are trying to peer farther across the universe or deep into the center of our own galaxy to learn more about their structure, formation and evolution.
