Isotopes with ocean circulation information

Fri, 04/07/2017 - 19:33
The Thorium-230 isotope in the marine sediment is used for paleo researchers to calibrate and normalize particle fluxes of past times. The isotope is present both in the water column and in the ocean sediments, the latter being the item for marine paleo geologists to examine.

NASA Sees Tropical Cyclone Ernie Intensify

Fri, 04/07/2017 - 19:07
The storm formerly known as tropical cyclone 15S, now called Tropical Cyclone Ernie continued to strengthen as NASA's Aqua satellite captured a visible image that showed the storm developed an eye.

Record New Renewable Power Capacity Added at Lower Cost

Fri, 04/07/2017 - 16:50
As the cost of clean technology continues to fall, the world added record levels of renewable energy capacity in 2016, at an investment level 23 per cent lower than the previous year, according to new research published today by UN Environment, the Frankfurt School-UNEP Collaborating Centre, and Bloomberg New Energy Finance.Global Trends in Renewable Energy Investment 2017 finds that wind, solar, biomass and waste-to-energy, geothermal, small hydro and marine sources added 138.5 gigawatts to global power capacity in 2016, up 8 per cent from the 127.5 gigawatts added the year before. The added generating capacity roughly equals that of the world's 16 largest existing power producing facilities combined.

Tropical lowland frogs at greater risk from climate warming than high-elevation species, study shows

Fri, 04/07/2017 - 14:55
A new study of Peruvian frogs living at a wide variety of elevations—from the Amazon floodplain to high Andes peaks—lends support to the idea that lowland amphibians are at higher risk from future climate warming.

How Changes in Rainfall Impact the World Economy

Fri, 04/07/2017 - 14:49
An afternoon rainstorm might seem like an inconvenience at times, but rainfall is an essential part of the world ecosystem. Most of us know this.

ALMA Captures Dramatic Stellar Fireworks

Fri, 04/07/2017 - 14:44
1350 light years away, in the constellation of Orion (the Hunter), lies a dense and active star formation factory called the Orion Molecular Cloud 1 (OMC-1), part of the same complex as the famous Orion Nebula. Stars are born when a cloud of gas hundreds of times more massive than our Sun begins to collapse under its own gravity. In the densest regions, protostars ignite and begin to drift about randomly. Over time, some stars begin to fall toward a common centre of gravity, which is usually dominated by a particularly large protostar — and if the stars have a close encounter before they can escape their stellar nursery, violent interactions can occur.

Satellites map carbon sequestered by forests, with accuracy of up to ten metres

Fri, 04/07/2017 - 14:40
Led by VTT, the EU North State project has developed a new method of using satellite images to evaluate the forest carbon balance. The carbon balance indicates how much carbon is sequestered or released by forests each year. This enables the carbon balance to be displayed on digital maps, with an accuracy of up to ten metres.

The Vanishing Nile: A Great River Faces a Multitude of Threats

Thu, 04/06/2017 - 13:49
The Nile River is under assault on two fronts – a massive dam under construction upstream in Ethiopia and rising sea levels leading to saltwater intrusion downstream. These dual threats now jeopardize the future of a river that is the lifeblood for millions.

Tracking Collaboration For Sustainability and Social Impact

Thu, 04/06/2017 - 13:43
The transformation of business in the 21st century has many facets and a number of common characteristics. One of these is the presence of softer, more rounded edges toward consumers when it comes to transparency, communities when it comes to volunteerism and philanthropy, employees when it comes to engagement efforts, and the environment when it comes to sustainability.

Buckle up! Climate Change to Increase Severe Aircraft Turbulence

Thu, 04/06/2017 - 13:33
Turbulence strong enough to catapult unbuckled passengers and crew around the aircraft cabin could become twice or even three times as common because of climate change, according to a new study from the University of Reading published in Advances in Atmospheric Sciences (AAS), an international journal published by Springer and hosted by the Institute of Atmospheric Physics, Chinese Academy of Sciences.

University Research Teams to Study Potential Aeronautical Innovations

Thu, 04/06/2017 - 13:25
Imagine an aircraft structure that can change its shape in flight to reduce the sonic boom noise produced by supersonics airplanes. Or imagine an airliner that can take-off and fly with a quiet and energy efficient electric propulsion system.

Hybridization between Native and Invasive Trout is Increasing in the West

Thu, 04/06/2017 - 13:25
Hybridization, or the interbreeding of species, is increasing between native and invasive trout across the northern Rocky Mountains, according to a study released Tuesday by the U.S. Geological Survey and partners.

New function discovered for compound that may help slow aging

Wed, 04/05/2017 - 17:09
Researchers at Oregon State University have found that a compound called rapamycin has unusual properties that may help address neurologic damage such as Alzheimer’s disease.

Tiny Whiteflies Provide Insight into Stabilizing Manmade Drones During Takeoff

Wed, 04/05/2017 - 16:53
When whiteflies take off, they don't just spread their wings and fly. Just .03 of an inch long, these tiny insects possess a variety of sophisticated techniques that provide them with exceptional stability in the air. Tel Aviv University researchers now say that they may hold the secret to stabilizing the take-off of small robotic manmade flyers such as miniaturized drones.

Manatees Just Lost Their Status as Endangered Species

Tue, 04/04/2017 - 17:10
Manatees have just been downlisted from endangered to threatened; and while some are celebrating their recovery, many advocates are fearing that the move puts their future survival in jeopardy.

Scientists engineer sugarcane to produce biodiesel, more sugar for ethanol

Tue, 04/04/2017 - 17:04
A multi-institutional team led by the University of Illinois have proven sugarcane can be genetically engineered to produce oil in its leaves and stems for biodiesel production. Surprisingly, the modified sugarcane plants also produced more sugar, which could be used for ethanol production. 

You Could Soon Print Out Simple Electronics With Your Deskjet

Tue, 04/04/2017 - 16:49
Computers used to require entire buildings to operate. Now they fit in our pockets. Similarly, factory-size electronics manufacturing is approaching a contraction. Want proof? Look at that $50 printer on your desk and imagine, instead of using it to spit out a hard copy of that thank-you note, that you used it to print some digital memory.
