On Earth Day, Give Fiber Its Due...
April 22, 2015 02:14 PM - Guest Contributor, James Gowen, Verizon Chief Sustainability Officer
There's a touch of green associated with receiving phone service, using the Internet and streaming video over an all-fiber-optic network. It's not the color of laser-generated light that carries massive amounts of data through all-glass cables directly into homes and businesses. It's green in the sense of how much more environmentally friendly today’s fiber-based telecommunications networks are compared to copper wire and coaxial cable networks. Whether it's energy efficiency or reduced demand for raw materials and other resources, all-fiber networks are a winning strategy on many fronts — including environmental sustainability. As we approach the 45th celebration of Earth Day on April 22, it's a good time to reflect on how network and technology decisions made by major telecommunications companies don't just result in advanced, more reliable services. These decisions can also pay handsome dividends on the sustainability front.
Energy-tracking app encourages sustainable behaviors
April 22, 2015 01:33 PM - Editor, ENN
We've all heard of fitness trackers and apps that help us stay on track with our daily nutrition and exercise, but what about an app to monitor our personal energy usage and carbon footprint? Just in time for Earth Day, a team at the University of Wisconsin-Madison has created an energy-tracking app to make reducing day-to-day energy usage more accessible.
The importance of oceanic phytoplankton
April 14, 2015 07:52 AM - Roger Greenway, ENN
Do you have any idea just how many organizims are in seawater? Not the fish you can see, but the microscopic organizims you cant see?
Dip a beaker into any portion of the world’s oceans, and you’re likely to pull up a swirling mix of planktonic inhabitants. The oceans are teeming with more than 5,000 species of phytoplankton — microscopic plants in a kaleidoscope of shapes and sizes. Together, phytoplankton anchor the ocean’s food chain, supplying nutrients to everything from single-celled organisms on up to fish and whales.
Through photosynthesis, these tiny organisms supply more than half the world’s oxygen. When these plants die, they drift to the ocean bottom, or evaporate into the air as carbon — a process that generates more than half the world’s cycling carbon.
Fungi thrived in flooded Colorado homes months after waters receded
April 13, 2015 08:53 AM - University of Colorado Boulder
Basements that flooded after heavy rains deluged the Colorado Front Range in September 2013 had higher levels of airborne mold and other fungi months after the waters receded compared with basements that didn’t flood, according to a study by the University of Colorado Boulder.
What is the source of mysterious methane emissions at Four Corners?
April 8, 2015 08:20 AM - University of Colorado Boulder
A team of scientific investigators is now in the Four Corners region of the U.S. Southwest, aiming to uncover reasons for a mysterious methane hotspot detected from space by a European satellite. The joint project is working to solve the mystery from the air, on the ground, and with mobile laboratories.
“If we can verify the methane emissions found by the satellite, and identify the various sources, then decision makers will have critical information for any actions they are considering,” says Gabrielle Pétron, a scientist from the Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder, working in NOAA’s Earth System Research Laboratory (ESRL) and one of the mission’s investigators. Part of President Obama’s recent Climate Action Plan calls for reductions in U.S. methane emissions. NOAA is the National Oceanic and Atmospheric Administration.
Early warning system to detect algal blooms being launched by EPA
April 7, 2015 03:24 PM - US EPA Newsroom
The U.S. Environmental Protection Agency (EPA) announced today that it is developing an early warning indicator system using historical and current satellite data to detect algal blooms. EPA researchers will develop a mobile app to inform water quality managers of changes in water quality using satellite data on cyanobacteria algal blooms from three partnering agencies-- NASA, NOAA, and the U.S. Geological Survey.
The multi-agency project will create a reliable, standard method for identifying cyanobacteria blooms in U.S. freshwater lakes and reservoirs using ocean color satellite data. Several satellite data sets will be evaluated against environmental data collected from these water bodies, which allows for more frequent observations over broader areas than can be achieved by taking traditional water samples.
Europe focuses on food safety on World Health Day
April 7, 2015 07:07 AM - EurActiv
On World Health Day (7 April), European Commissioners Vytenis Andriukaitis and Neven Mimica highlight the importance of food safety, malnutrition, and fighting health threats both in the Union and in developing countries.
2015 is the European year for development (EYD). It is an opportunity to show how EU assistance is improving the lives of millions in developing countries; but also in Europe. Food safety, which is the theme of this year’s World Health Day, is a clear example of this.
Too often in Europe we take for granted that the food on our plates is safe. Europe should be proud that its 500 million consumers benefit from the highest food safety and health protection standards in the world, and that many other countries take them as the norm to be followed. However, we must not become complacent.
White fat, brown fat, now beige fat and obesity
April 4, 2015 08:58 AM - Universtiy of California San Francisco
Those extra pounds around your belly that no amount of exercise seems to shake off? That's not just fat; it's what scientists call white fat – unhealthy, energy-storing fat.
Brown fat, however, has been known to contain energy-burning, heat-producing qualities that could be key to helping people lose weight. The key is finding a way to increase brown fat in the body and reduce the white fat.
Hibernating mammals have brown fat, and human babies are born with it to help them keep warm outside the womb. Adults also have varying amounts of brown fat, but researchers weren't sure if it’s the same kind babies are born with, and if not, where it comes from.
The advantages of being a morning person
April 1, 2015 01:40 PM - Roger Greenway, ENN
There are many advantages of getting a good nights sleep. Turns out, the advantages are less if you are a night owl instead of a morning person.
Night owls are more likely to develop diabetes, metabolic syndrome and sarcopenia than early risers, even when they get the same amount of sleep, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
The study examined the difference between night and morning chronotypes, or a person's natural sleep-wake cycle. Staying awake later at night is likely to cause sleep loss, poor sleep quality, and eating at inappropriate times, which might eventually lead to metabolic change.
Why is Mars so different from Earth?
April 1, 2015 07:40 AM - Roger Greenway, ENN
Did Mars ever support life of any sort? Why is Mars so different from Earth? Can we deduce its history from current conditions?
NASA's Curiosity rover is using a new experiment to better understand the history of the Martian atmosphere by analyzing xenon.
While NASA's Curiosity rover concluded its detailed examination of the rock layers of the "Pahrump Hills" in Gale Crater on Mars this winter, some members of the rover team were busy analyzing the Martian atmosphere for xenon, a heavy noble gas.
Curiosity's Sample Analysis at Mars (SAM) experiment analyzed xenon in the planet's atmosphere. Since noble gases are chemically inert and do not react with other substances in the air or on the ground, they are excellent tracers of the history of the atmosphere. Xenon is present in the Martian atmosphere at a challengingly low quantity and can be directly measured only with on-site experiments such as SAM.
