Published Gravitational waves from colossal black holes found using 'cosmic clocks'
(via sciencedaily.com)
Original source 
You can't see or feel it, but everything around you -- including your own body -- is slowly shrinking and expanding. It's the weird, spacetime-warping effect of gravitational waves passing through our galaxy. New results are the first evidence of the gravitational wave background -- a sort of soup of spacetime distortions pervading the entire universe and long predicted to exist by scientists.
Published Evaluating cybersecurity methods
(via sciencedaily.com)
Original source 
Researchers created a generic framework that enables an engineer or scientist to evaluate the effectiveness of defense schemes that seek to limit a hacker's ability to learn secret information by observing the behavior of a victim computer program.
Published Turning old maps into 3D digital models of lost neighborhoods
(via sciencedaily.com)
Original source 
Imagine strapping on a virtual reality headset and 'walking' through a long-gone neighborhood in your city -- seeing the streets and buildings as they appeared decades ago. That's a very real possibility now that researchers have developed a method to create 3D digital models of historic neighborhoods using machine learning and historic Sanborn Fire Insurance maps.
Published NeuWS camera answers 'holy grail problem' in optical imaging
(via sciencedaily.com)
Original source 
Engineers have demonstrated full-motion video camera technology that can 'see' through light-scattering media. The research could potentially be used in cameras that peer through fog, smoke, driving rain, murky water and parts of the body that hide tumors and other lesions.
Published Research reveals sources of CO2 from Aleutian-Alaska Arc volcanoes
(via sciencedaily.com)
Original source 
Scientists have wondered what happens to the organic and inorganic carbon that Earth's Pacific Plate carries with it as it slides into the planet's interior along the volcano-studded Ring of Fire. A new study suggests a notable amount of such subducted carbon returns to the atmosphere rather than traveling deep into Earth's mantle.
Published Neutrons look inside working solid-state battery to discover its key to success
(via sciencedaily.com)
Original source 
Researchers have used neutron reflectometry to peer inside a working solid-state battery and monitor its electrochemistry. They discovered that its excellent performance results from an extremely thin layer, across which charged lithium atoms quickly flow as they move from anode to cathode and blend into a solid electrolyte.
Published Acutely exposed to changing climate, many Greenlanders do not blame humans
(via sciencedaily.com)
Original source 
A new survey shows that the largely Indigenous population of Greenland is highly aware that the climate is changing, and far more likely than people in other Arctic nations to say they are personally affected. Yet, many do not blame human influences -- especially those living traditional subsistence lifestyles most directly hit by the impacts of rapidly wasting ice and radical changes in weather.
Published Climate change will increase impacts of volcanic eruptions
(via sciencedaily.com)
Original source 
Volcanic disasters have been studied since Pompeii was buried in 79 A.D., leading the public to believe that scientists already know why, where, when and how long volcanoes will erupt. But a volcanologist said these fundamental questions remain a mystery.
Published Geologists are using artificial intelligence to predict landslides
(via sciencedaily.com)
Original source 
Many factors influence where a landslide will occur, including the shape of the terrain, its slope and drainage areas, the material properties of soil and bedrock, and environmental conditions like climate, rainfall, hydrology and ground motion resulting from earthquakes. Geologists have developed a new technique that uses artificial intelligence to better predict where and why landslides may occur could bolster efforts to protect lives and property in some of the world's most disaster-prone areas. The new method improves the accuracy and interpretability of AI-based machine-learning techniques, requires far less computing power and is more broadly applicable than traditional predictive models.
Published ALMA digs deeper into the mystery of planet formation
(via sciencedaily.com)
Original source 
An international research team has observed disks around 19 protostars with a very high resolution to search for the earliest signs of planet formation. This survey was motivated by the recent findings that planet formation may be well-underway in the more-evolved proto-planetary disks, but until now there had been no systematic study to search for signs of planet formation in younger protostellar systems.
Published Researchers unearth the mysteries of how Turkey's East Anatolian fault formed
(via sciencedaily.com)
Original source 
An international team has, for the first time, accurately determined the age of the East Anatolian fault, allowing geologists to learn more about its seismic history and tendency to produce earthquakes.
Published 'Electronic skin' from bio-friendly materials can track human vital signs with ultrahigh precision
(via sciencedaily.com)
Original source 
Researchers have used materials inspired by molecular gastronomy to create smart wearables that surpassed similar devices in terms of strain sensitivity. They integrated graphene into seaweed to create nanocomposite microcapsules for highly tunable and sustainable epidermal electronics. When assembled into networks, the tiny capsules can record muscular, breathing, pulse, and blood pressure measurements in real-time with ultrahigh precision.
Published Squid-inspired soft material is a switchable shield for light, heat, microwaves
(via sciencedaily.com)
Original source 
With a flick of a switch, current technologies allow you to quickly change materials from being dark to light, or cold to hot, just by blocking or transmitting specific wavelengths. But now, inspired by squid skin, researchers report a soft film that can regulate its transparency across a large range of wavelengths -- visible, infrared and microwave -- simultaneously. They demonstrated the material in smart windows and in health monitoring and temperature management applications.
Published What are the characteristics of foreshocks for large earthquakes?
(via sciencedaily.com)
Original source 
Seismologists agree that foreshocks are the most widely identified signal of an upcoming mainshock earthquake. But do these foreshock sequences have distinctive characteristics that separate them from aftershock sequences, and could these characteristics be used to help forecast mainshocks?
Published Undergrad-driven project reveals drought's effects on painted turtles
(via sciencedaily.com)
Original source 
A projected rise in droughts could muddy the waters for painted turtles and some fellow freshwater-dwelling reptiles, says 11 years of data collected by 50-plus undergraduates. Two recent studies based on the data suggest that drought can lower the survival odds, slow the growth and even skew the ratio of female-to-male painted turtles inhabiting the ponds of the Cornhusker State. Those outcomes emerged despite the water level of a sampled pond in southwestern Nebraska remaining relatively steady throughout the observed periods of drought.
Published Squash bugs are attracted to and eat each other's poop to stock their microbiome
(via sciencedaily.com)
Original source 
Squash bugs, a common and difficult-to-control agricultural pest, need healthy bacteria in their gut to grow and stay alive. However, they do not acquire any bacteria from their parents when they are first born, leaving them vulnerable until their microbiome can be stocked. Researchers report that, to acquire these healthy bacteria, young bugs innately seek out and eat the poop from older squash bugs.
Published Mountains vulnerable to extreme rain from climate change
(via sciencedaily.com)
Original source 
A new study finds that as rising global temperatures shift snow to rain, mountains across the Northern Hemisphere will be hotspots for extreme rainfall events that could trigger floods and landslides -- potentially impacting a quarter of the world's population.
Published How urea may have been the gateway to life
(via sciencedaily.com)
