(via sciencedaily.com)
Original source 
Climate change will increase the future value of residential rooftop solar panels across the United States by up to 19% by the end of the century, according to a new study.
Published Warming of Antarctic deep-sea waters contribute to sea level rise in North Atlantic, study finds
(via sciencedaily.com)
Original source 
Analysis of mooring observations and hydrographic data suggest the Atlantic Meridional Overturning Circulation deep water limb in the North Atlantic has weakened. Two decades of continual observations provide a greater understanding of the Earth's climate regulating system.
Published Energy scientists unravel the mystery of gold's glow
(via sciencedaily.com)
Original source 
EPFL researchers have developed the first comprehensive model of the quantum-mechanical effects behind photoluminescence in thin gold films; a discovery that could drive the development of solar fuels and batteries.
Published Light show in living cells
(via sciencedaily.com)
Original source 
Observing proteins precisely within cells is extremely important for many branches of research but has been a significant technical challenge -- especially in living cells, as the required fluorescent labeling had to be individually attached to each protein. The research group has now overcome this hurdle: With a method called 'vpCells,' it is possible to label many proteins simultaneously, using five different fluorescent colors.
Published Scientists trigger mini-earthquakes in the lab
(via sciencedaily.com)
Original source 
Earthquakes and landslides are famously difficult to predict and prepare for. By studying a miniature version of the ground in the lab, scientists have demonstrated how these events can be triggered by a small external shock wave. Bring a flotation device: it involves the ground briefly turning into a liquid!
Published Why can zebrafish regenerate damaged heart tissue, while other fish species cannot?
(via sciencedaily.com)
Original source 
A heart attack will leave a permanent scar on a human heart, yet other animals, including zebrafish, can clear cardiac scar tissue and regrow damaged muscle as adults. Biologists sheds new light on how zebrafish heal heart tissue by comparing how this species responds to heart injury with medaka, a fish species that cannot regenerate cardiac tissue.
Published Octopus inspires new suction mechanism for robots
(via sciencedaily.com)
Original source 
A new robotic suction cup which can grasp rough, curved and heavy stone, has been developed by scientists.
Published Teaching a computer to type like a human
(via sciencedaily.com)
Original source 
A new typing model simulates the typing process instead of just predicting words.
Published Coal train pollution increases health risks and disparities
(via sciencedaily.com)
Original source 
The first health impact study of coal train pollution centers on the San Francisco Bay Area, with scientists finding communities near passing coal trains suffer worse health outcomes.
Published When thoughts flow in one direction
(via sciencedaily.com)
Original source 
Contrary to previous assumptions, nerve cells in the human neocortex are wired differently than in mice. The study found that human neurons communicate in one direction, while in mice, signals tend to flow in loops. This increases the efficiency and capacity of the human brain to process information. These discoveries could further the development of artificial neural networks.
Published Mess is best: Disordered structure of battery-like devices improves performance
(via sciencedaily.com)
Original source 
The energy density of supercapacitors -- battery-like devices that can charge in seconds or a few minutes -- can be improved by increasing the 'messiness' of their internal structure. Researchers used experimental and computer modelling techniques to study the porous carbon electrodes used in supercapacitors. They found that electrodes with a more disordered chemical structure stored far more energy than electrodes with a highly ordered structure.
Published Skyrmions move at record speeds: A step towards the computing of the future
(via sciencedaily.com)
Original source 
Scientists have discovered that the magnetic nanobubbles known as skyrmions can be moved by electrical currents, attaining record speeds up to 900 m/s. Anticipated as future bits in computer memory, these nanobubbles offer enhanced avenues for information processing in electronic devices. Their tiny size provides great computing and information storage capacity, as well as low energy consumption. Until now, these nanobubbles moved no faster than 100 m/s, which is too slow for computing applications. However, thanks to the use of an antiferromagnetic material as medium, the scientists successfully had the skyrmions move 10 times faster than previously observed. These results offer new prospects for developing higher-performance and less energy-intensive computing devices.
Published One third of China's urban population at risk of city sinking, new satellite data shows
(via sciencedaily.com)
Original source 
Land subsidence is overlooked as a hazard in cities, according to new research. Scientists used satellite data that accurately and consistently maps land movement across China.
Published Novel material supercharges innovation in electrostatic energy storage
(via sciencedaily.com)
Original source 
Scientists have developed artificial heterostructures made of freestanding 2D and 3D membranes that have an energy density up to 19 times higher than commercially available capacitors.
Published Potential new treatment path for lasting Lyme disease symptoms
(via sciencedaily.com)
Original source 
Researchers have identified a potential new treatment for persistent neurological symptoms of Lyme disease, commonly seen even after antibiotic use. The study found that fibroblast growth factor receptor inhibitors, previously studied in cancer, significantly reduced inflammation and cell death in infected brain and nerve tissues.
Published Metabolic health before vaccination determines effectiveness of anti-flu response
(via sciencedaily.com)
Original source 
The annual influenza vaccine has become less effective on average over time. One reason may be reduced vaccine efficacy in people with obesity than those with a healthier body mass index (BMI), while the number of people with high BMI grows. Findings showed switching mice to a healthy diet four weeks before influenza vaccination protected 100% from a later flu exposure, despite still having a high BMI.
Published Fourteen years after the Gulf of Mexico oil spill, endemic fishes face an uncertain future
(via sciencedaily.com)
Original source 
The 2010 Gulf of Mexico Deepwater Horizon oil spill, the largest accidental spill in history, released almost 100 million gallons of oil, causing significant pollution. A decade later, its long-term effects remain unclear. A study investigating the impact on endemic fish species found 29 of 78 species unreported in museum collections since the spill, suggesting potential loss of biodiversity.
Published Marine microbial populations: Potential sensors of the global change in the ocean
(via sciencedaily.com)
Original source 
Animal and plant populations have been extensively studied, which has helped to understand ecosystem processes and evolutionary adaptations. However, this has not been the case with microbial populations due to the impossibility of isolating, culturing and analyzing the genetic content of the different species and their individuals in the laboratory. Therefore, although it is known that populations of microorganisms include a great diversity, this remains largely uncharacterized.
Published Data-driven music: Converting climate measurements into music
(via sciencedaily.com)
Original source 
A geo-environmental scientist from Japan has composed a string quartet using sonified climate data. The 6-minute-long composition -- entitled 'String Quartet No. 1 'Polar Energy Budget'-- is based on over 30 years of satellite-collected climate data from the Arctic and Antarctic and aims to garner attention on how climate is driven by the input and output of energy at the poles.
Published RNA's hidden potential: New study unveils its role in early life and future bioengineering
(via sciencedaily.com)
Original source 
The origin of life continues to remain a matter of debate. The ribonucleic acid (RNA) world hypothesis proposes that 'ribozymes' which store genetic information and possess catalytic functions may have supported the activities of early life forms. Now, researchers explore how RNA elongation is regulated allosterically, shedding light on its impact on early life processes and offering insights into the fabrication of arbitrary RNA nanostructures with various modern applications.
