Jupiter's moon Europa may have had a slow evolution      (via sciencedaily.com)     Original source 

Europa may have a metamorphic origin for the ocean. While some scientists speculated this, a research team shows that if Europa indeed formed from hydrated rocks (i.e., rocks have hydrogen and oxygen), then enough of Europa's interior should get hot enough to release water directly from the hydrated rocks to form the ocean and ice shell.

Engineers develop a soft, printable, metal-free electrode      (via sciencedaily.com)     Original source 

Engineers developed a metal-free, Jelly-like material that is as soft and tough as biological tissue and can conduct electricity similarly to conventional metals. The new material, which is a type of high-performance conducting polymer hydrogel, may one day replace metals in the electrodes of medical devices.

Researchers demystify the unusual origin of the Geminids meteor shower      (via sciencedaily.com)     Original source 

Princeton researchers used observations from NASA's Parker Solar Probe mission to deduce that it was likely a violent, catastrophic event -- such as a high-speed collision with another body or a gaseous explosion -- that created the Geminids meteoroid stream. Mysteries surrounding the origin of the Geminids have long fascinated scientists because, while most meteor showers are created when a comet emits a tail of ice and dust, the Geminids stem from an asteroid -- a chunk of rock that normally does not produce a tail. Until now, this unusual meteoroid stream had only been studied from Earth.

Energy harvesting via vibrations: Researchers develop highly durable and efficient device      (via sciencedaily.com)     Original source 

An international research group has engineered a new energy-generating device by combining piezoelectric composites with carbon fiber-reinforced polymer (CFRP), a commonly used material that is both light and strong. The new device transforms vibrations from the surrounding environment into electricity, providing an efficient and reliable means for self-powered sensors.

Scientists report 'benchmarks' for extreme space weather      (via sciencedaily.com)     Original source 

Extreme space weather threatens vital satellites orbiting the Earth, including the Global Navigation Satellite Systems (GNSS) which pass through the heart of the outer radiation belt. New research has now determined a series of benchmarks for the likely severity of extreme space weather events in GPS orbit.

Earth was created much faster than we thought: This makes the chance of finding other habitable planets in the Universe more likely      (via sciencedaily.com)     Original source 

Over the past decades, researchers thought Earth was created over a period of more than 100 million years. However, a new study from suggests that the creation of Earth was much more rapid, and that water and other essential ingredients for life were delivered to Earth very early on.

Plate tectonics not required for the emergence of life      (via sciencedaily.com)     Original source 

New finding contradicts previous assumptions about the role of mobile plate tectonics in the development of life on Earth. Moreover, the data suggests that 'when we're looking for exoplanets that harbor life, the planets do not necessarily need to have plate tectonics,' says the lead author of a new paper.

Sun's coldest region stores secret to heating million-degree corona      (via sciencedaily.com)     Original source 

Researchers have unveiled the discovery of intense wave energy from a relatively cool, dark and strongly magnetized plasma region on the Sun, capable of traversing the solar atmosphere and maintaining temperatures of a million degrees Kelvin inside the corona. Researchers say the finding is the latest key to unraveling a host of related mysteries pertaining to Earth's nearest star.

Key building block for life found at Saturn's moon Enceladus      (via sciencedaily.com)     Original source 

The search for extraterrestrial life in our solar system just got more exciting. A team of scientists has discovered new evidence that the subsurface ocean of Saturn's moon Enceladus contains a key building block for life. The team directly detected phosphorus in the form of phosphates originating from the moon's ice-covered global ocean using data from NASA's Cassini mission. Cassini explored Saturn and its system of rings and moons for over 13 years.

All-electric rideshare fleet could reduce carbon emissions, increase traffic issues      (via sciencedaily.com)     Original source 

Two major ridesharing companies have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. To understand additional impacts of this transition, researchers conducted life-cycle comparisons of battery-powered electric vehicle fleets to a gas-powered one, using real-world rideshare data. They found up to a 45% reduction in greenhouse gas emissions from full electrification; however, traffic problems and air pollution could increase.
