A new study shows that if U.S. nuclear power plants are retired, the burning of coal, oil, and natural gas to fill the energy gap could cause more than 5,000 premature deaths.
Published This elephant's self-taught banana peeling offers glimpse of elephants' broader abilities
(via sciencedaily.com)
Original source 
Elephants like to eat bananas, but they don't usually peel them first in the way humans do. A new report however, shows that one very special Asian elephant named Pang Pha picked up banana peeling all on her own while living at the Berlin Zoo. She reserves it for yellow-brown bananas, first breaking the banana before shaking out and collecting the pulp, leaving the thick peel behind.
Published Solar cells charging forward
(via sciencedaily.com)
Original source 
An environmentally friendlier solution to solar cell production with enhanced performance utilizes PEDOT:PSS/silicon heterojunction solar cells. This hybrid type is made of organic-inorganic material, which could potentially ease the production process compared to conventional silicon-only solar cells. It avoids manufacturing solar cells in vacuums and high-temperature processes, which require large and expensive equipment and a great amount of time.
Published Rooting out how plants control nitrogen use
(via sciencedaily.com)
Original source 
Nitrogen is such a crucial nutrient for plants that vast quantities of nitrogen-containing fertilizers are spread on farmlands worldwide. However, excess nitrogen in the soil and in drainage run-off into lakes and rivers causes serious ecological imbalances. A recent study has uncovered the regulatory mechanisms at work when plants utilize nitrogenous fertilizers in their roots, a positive step in the quest to generate crops that require less fertilizer while still producing the yields needed to feed the world.
Published What is it good for? Absolutely one thing: Luna moths use their tails solely for bat evasion
(via sciencedaily.com)
Original source 
Scientists recently discovered that Luna moths use their long tails as decoys to throw bats off their trail. But their tails also make Luna moths might also make them stand out to potential mates and make them more conspicuous to lurking predators. A pair of complementary studies looked to see whether these colorful, bat-deflecting appendages might come with any additional costs or benefitt
Published Scientists show how we can anticipate rather than react to extinction in mammals
(via sciencedaily.com)
Original source 
Most conservation efforts are reactive. Typically, a species must reach threatened status before action is taken to prevent extinction, such as establishing protected areas. A new study shows that we can use existing conservation data to predict which currently unthreatened species could become threatened and take proactive action to prevent their decline before it is too late.
Published Engineered plants produce sex perfume to trick pests and replace pesticides
(via sciencedaily.com)
Original source 
Tobacco plants have been engineered to manufacture an alluring perfume of insect sex pheromones, which could be used to confuse would-be pests looking for love and reduce the need for harmful pesticides.
Published Here's how a worm's embryonic cells changed its development potential
(via sciencedaily.com)
Original source 
Researchers have spotted how specific proteins within the chromosomes of roundworms enable their offspring to produce specialized cells generations later, a startling finding that upends classical thinking that hereditary information for cell differentiation is mostly ingrained within DNA and other genetic factors.
Published Scientists discover a way Earth's atmosphere cleans itself
(via sciencedaily.com)
Original source 
Human activities emit many kinds of pollutants into the air, and without a molecule called hydroxide (OH), many of these pollutants would keep aggregating in the atmosphere.
Published In Florida study, nonnative leaf-litter ants are replacing native ants
(via sciencedaily.com)
Original source 
A new look at decades of data from museum collections and surveys of leaf-litter ants in Florida reveals a steady decline in native ants and simultaneous increase in nonnative ants -- even in protected natural areas of the state, researchers report.
Published Woolly mammoths evolved smaller ears and woolier coats over the 700,000 years that they roamed the Siberian steppes
(via sciencedaily.com)
Original source 
A team of researchers compared the genomes of woolly mammoths with modern day elephants to find out what made woolly mammoths unique, both as individuals and as a species. The investigators report that many of the woolly mammoth's trademark features -- including their woolly coats and large fat deposits -- were already genetically encoded in the earliest woolly mammoths, but these and other traits became more defined over the species' 700,000+ year existence. They also identified a gene with several mutations that may have been responsible for the woolly mammoth's miniscule ears.
Published Simple but revolutionary modular organoids
(via sciencedaily.com)
Original source 
A team has developed an ingenious device, using layers of hydrogels in a cube-like structure, that allows researchers to construct complex 3D organoids without using elaborate techniques. The group also recently demonstrated the ability to use the device to build organoids that faithfully reproduce the asymmetric genetic expression that characterizes the actual development of organisms.
Published Spike in major league home runs tied to climate change
(via sciencedaily.com)
Original source 
A new study identifies the influence of climate change in the greater number of home runs in major league baseball in recent years. The researchers found that more than 500 home runs since 2010 can be attributed to warmer, thinner air caused by global warming, and that rising temperatures could account for 10% or more of home runs by 2100 if greenhouse gas emissions continue unabated. The researchers examined how the average number of home runs per year could rise for each major league ballpark with every 1-degree Celsius increase in the global average temperature.
Published Environmental impact reports hugely underestimate consequences for wildlife
(via sciencedaily.com)
Original source 
Research shows that environmental impact reports hugely underestimate the consequences of new developments for wildlife. This is because they don't take into account how birds and other animals move around between different sites. The research shows how a planned airport development in Portugal could affect more than 10 times the number of Black-tailed Godwits estimated in a previous Environmental Impact Assessment. The team have been studying these Godwits across Europe for over 30 years but they say that any species that moves around is likely to be under-represented by such reports.
Published Case for Candida auris wastewater surveillance
(via sciencedaily.com)
Original source 
Researchers say tracking methodology in Southern Nevada fungal outbreak provides blueprint for monitoring and responding to emerging global public health threat.
Published Researchers clear the way for well-rounded view of cellular defects
(via sciencedaily.com)
Original source 
New research investigates how cells divide, particularly in the fibrous environment of living tissue. Cells are typically studied in a flat environment, and the difference between flat and fibrous landscapes opens new windows into the behavior of cells and the diseases that impact them.
Published Fully recyclable printed electronics ditch toxic chemicals for water
(via sciencedaily.com)
Original source 
Engineers have produced fully recyclable printed electronics that replace the use of chemicals with water in the fabrication process. By bypassing the need for hazardous chemicals, the demonstration points down a path industry could follow to reduce its environmental footprint and human health risks.
Published Broccoli consumption protects gut lining, reduces disease, in mice
(via sciencedaily.com)
Original source 
Broccoli is known to be beneficial to our health. For example, research has shown that increased consumption of the cruciferous vegetable decreases incidence of cancer and type 2 diabetes. In a recent study, researchers found that broccoli contains certain molecules that bind to a receptor within mice and help to protect the lining of the small intestine, thereby inhibiting the development of disease. The findings lend support to the idea that broccoli truly is a 'superfood.'
Published Blind dating in bacteria evolution
(via sciencedaily.com)
