Do You Conserve Water? You Could Probably Stand to Do Much More

Nearly 15 percent of the contiguous United States is suffering from moderate to severe drought, which makes water conservation critical in certain parts of the country. How do we convince people to save more water, though?

That’s the question that professors at the University of Florida Institute of Food and Agricultural Sciences put to the test. They polled over 1,000 people in Florida to determine which types of people would respond best to conservation efforts, and the answer is a little counterintuitive: target people who are already saving some water.

NASA satellite sees heavy rain in tropical depression Bonnie

The Global Precipitation Measurement mission known as GPM passed over Tropical Depression Bonnie and found heavy rainfall from a few thunderstorms within.

Tropical Storm Bonnie weakened to a tropical depression on May 29, 2016. The circulation was labeled as "post-tropical" and has been moving very slowly to the northeast near the Carolinas coastline. Bonnie developed organized convection near the center and on June 2, 2016 the system was again labeled a tropical depression.

Where and when were dogs first domesticated?

Supported by funding from the European Research Council and the Natural Environment Research Council, a large international team of scientists compared genetic data with existing archaeological evidence and show that man’s best friend may have emerged independently from two separate (possibly now extinct) wolf populations that lived on opposite sides of the Eurasian continent. This means that dogs may have been domesticated not once, as widely believed, but twice.

A major international research project on dog domestication, led by the University of Oxford, has reconstructed the evolutionary history of dogs by first sequencing the genome (at Trinity College Dublin) of a 4,800-year old medium-sized dog from bone excavated at the Neolithic Passage Tomb of Newgrange, Ireland. The team (including French researchers based in Lyon and at the National Museum of Natural History in Paris) also obtained mitochondrial DNA from 59 ancient dogs living between 14,000 to 3,000 years ago and then compared them with the genetic signatures of more than 2,500 previously studied modern dogs.

 

NASA studies details of a greening Arctic

The northern reaches of North America are getting greener, according to a NASA study that provides the most detailed look yet at plant life across Alaska and Canada. In a changing climate, almost a third of the land cover - much of it Arctic tundra - is looking more like landscapes found in warmer ecosystems.

With 87,000 images taken from Landsat satellites, converted into data that reflects the amount of healthy vegetation on the ground, the researchers found that western Alaska, Quebec and other regions became greener between 1984 and 2012. The new Landsat study further supports previous work that has shown changing vegetation in Arctic and boreal North America.

Map Shows Where Fossil Fuels Should Stay in the Ground

We know that we need to keep the vast majority of fossil fuels in the ground in order to limit global warming to 1.5 degrees Celsius. Now, a new project from the University of Arizona shows us exactly where we need to keep these fuels in the ground.

Renewable Energy Closes "The Gap"

The Renewables Energy Policy Network for the 21st Century - shows that renewables are now firmly established as competitive, mainstream sources of energy in many countries around the world, closing the gap between the energy haves- and have-nots

High blood pressure linked to short-, long-term exposure to some air pollutants

High blood pressure was associated with short-term and long-term exposure to some air pollutants commonly associated with the burning/combustion of fossil fuels, dust and dirt, a new study shows. Researchers suggest people -- especially those with high blood pressure -- limit their time outdoors when pollution levels are high.

National Academy of Sciences Weighs In On Genetically-Engineered Foods

The National Academy of Sciences has some conclusions to share about genetically-engineered foods — 420 pages worth. And no matter which side of the fence you stand on when it comes to this divisive topic, you probably aren’t going to like what the nonprofit has to say.

The report, Genetically Engineered Organisms: Experiences and Prospects, was released last week online amid a flurry of news articles that attempted to breathlessly summarize the findings in a few short sentences. Some expressed disappointment in the authors’ inconclusive findings; many others attempted to pin a final yea-or-nay viewpoint on the Academy’s nine-chapter investigation.

Who gets to influence the climate negotiations?

The influence of fossil fuel corporations was strongly questioned by developing countries in the post-Paris meeting of the climate change negotiations in Bonn last week. Climate Trackers Pavlos Georgiadis, Renee Karunungan and Anna Pérez Català highlight the key issues that were debated. 

A number of developing countries, led by Ecuador, Guatemala and Bolivia are now calling for concrete measures to define how the public policy making process interacts with the private sector in climate change negotiations. What they want is special attention to be given to concerns over potential conflicts of interest between the industry and the implementation of the Paris Agreement.

Honeybees pick up 'astonishing' number of pesticides via non-crop plants

A Purdue University study shows that honeybees collect the vast majority of their pollen from plants other than crops, even in areas dominated by corn and soybeans, and that pollen is consistently contaminated with a host of agricultural and urban pesticides throughout the growing season.
