Think Different: Apple and conservation
April 17, 2015 07:14 AM - Andrew Burger, Triple Pundit
Marking a precedent-setting conservation partnership, Apple and the Conservation Fund will purchase two large areas of working forest, the organizations announced on Thursday. The move is expected to conserve “more than 36,000 acres of working forestland in Maine and North Carolina, ensuring these forests stay forests and any timber on the land is harvested sustainably,” the partners said in a joint announcement.
This initial purchase of U.S. working forestland marks “the beginning of a worldwide effort, one that represents a new approach as it reassesses its impact on the world’s paper supply chain,” Lisa P. Jackson, Apple’s vice president of environmental initiatives, and Larry Selzer, president and CEO of the Conservation Fund, wrote in a Medium op-ed. Prior to joining Apple, Jackson led the U.S. EPA as President Barack Obama’s EPA Administrator from 2009 to 2013.
Study shows how climate affects biodiversity
April 16, 2015 03:18 PM - Uppsala University via AlphaGalileo
A key question in the climate debate is how the occurrence and distribution of species is affected by climate change. But without information about natural variation in species abundance it is hard to answer. In a major study, published today in the leading scientific journal Current Biology, researchers can now for the first time give us a detailed picture of natural variation.
Bird populations decline years after Fukushima's nuclear catastrophe
April 16, 2015 08:40 AM - Steven Powell, University of South Carolina
This is the time of year when birds come out and really spread their wings, but since a disastrous day just before spring’s arrival four years ago, Japan’s Fukushima province has not been friendly to the feathered. And as several recent papers from University of South Carolina biologist Tim Mousseau and colleagues show, the avian situation there is just getting worse.
Human sweat conveys our emotional state!
April 16, 2015 06:50 AM - ASSOCIATION FOR PSYCHOLOGICAL SCIENCE via EurekAlert.
Humans may be able to communicate positive emotions like happiness through the smell of our sweat, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The research indicates that we produce chemical compounds, or chemosignals, when we experience happiness that are detectable by others who smell our sweat.
While previous research has shown that negative emotions related to fear and disgust are communicated via detectable regularities in the chemical composition of sweat, few studies have examined whether the same communicative function holds for positive emotions.
New oil repellant materials could help clean up oil spills
April 15, 2015 03:34 PM - Scott Gordon, University of Wisconsin-Madison
University of Wisconsin-Madison researchers have announced a significant step forward in the development of materials that can ward off oil — a discovery that could lead to new protective coatings and better approaches to cleaning up oil spills. In a new paper in the journal Advanced Functional Materials, professor of chemical and biological engineering David Lynn and assistant scientist Uttam Manna describe new coatings that are extremely oil-repellant (or "superoleophobic") in underwater environments.
Japan's 'scientific whaling' fail
April 15, 2015 09:12 AM - Tony Press, The Ecologist
Japan's latest plans for 'scientific whaling' in the Southern Ocean have fallen at the first hurdle, writes Tony Press. The IWC's expert panel says Japan's proposal contains 'insufficient information' on which to judge its validity, in particular the need for the 'lethal sampling' of over 3,996 Minke whales that is central to the research plan.
How California distributes scarce water
April 15, 2015 08:09 AM - Dan Charles, NPR
The state of California is asking a basic question right now that people often fight over: What's a fair way to divide up something that's scarce and valuable? That "something," in this case, is water.
There's a lot at stake, including your very own nuts, fruit and vegetables, because most of the water that's up for grabs in California goes to farmers. This year, some farmers will get water, and others will not, simply based on when their land was first irrigated.
Consider, for instance, the case of Cannon Michael. He grows tomatoes and melons in California's Central Valley. And despite the drought, he'll still grow them this year.
What lead is doing to our students
April 14, 2015 04:15 PM - Jasmine Garsd, NPR
Every child's ability to succeed in school is influenced by lots of external factors: teacher quality, parenting, poverty, geography, to name a few. But far less attention has been paid to the power of a child's bedroom walls. Or, rather, the paint that's on them and the lead that may be in that paint. A new study published in the Harvard Educational Review suggests that efforts to reduce kids' lead exposure have led to tangible academic gains in Massachusetts.
Report finds rise in ER visits following heavy rainfall
April 14, 2015 09:02 AM - University of Illinois at Chicago
Consumers whose drinking water can be contaminated by the release of untreated wastewater after heavy rains face increased risk for gastrointestinal illness, according to a report in the journal Environmental Health Perspectives. “Combined” sewer systems collect both sewage and stormwater runoff on the way to treatment facilities. When heavy rainfall fills these systems beyond their capacity, untreated wastewater can back up into homes. To reduce the risk of home flooding during heavy precipitation, municipalities often discharge some of the untreated flow into nearby bodies of water. The release of untreated waste is known as a combined sewer overflow.
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.
