Alaska hit by more than 230 small earthquakes since Friday
(CNN) — More than 1,000 aftershocks of magnitude 1.5 or greater have shaken Alaska since Friday’s big quake knocked out power, ripped open roads and splintered buildings in Anchorage, US Geological Survey geophysicist Randy Baldwin said Sunday.
The majority were of a magnitude of 2.5 or weaker, meaning they weren’t likely felt. But more than 350 of the aftershocks were higher than 2.5, according to USGS data.
Why do so many quakes strike Alaska?

Equipment for Moon Mining Operations are Being Developed
The technology needed for mining water ice on the moon and converting it into fuel is pretty straight forward. Various groups are already making the actual needed hardware. Paragon Space Development and Giner are already making key pieces of what is needed. If we are making large amounts of fuel on the moon then we are massively lowering the cost of all missions in space. The cost of anything from higher earth orbit and beyond becomes several times cheaper.
After the D-day invasion, the Allies made a temporary port. We need to move beyond thinking science missions to working on logistics and supply chains.

Life on Earth Could Have Started Thanks to a Simple Ingredient We Use Every Day
If classic monster movies and old science experiments are to be believed, life begins with a spark.
Not everybody is convinced by this kind of origin story, so the search continues for sources of energy capable of transforming a prebiotic soup into a life-generating dish. Maybe the secret ingredient isn’t anything more shocking than a pinch of salt.
A new study led by researchers from the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology in Japan has turned their attention to common old sodium chloride as a potential conduit for the chemical energy required for early biochemistry.

New catalyst material produces abundant cheap hydrogen
QUT chemistry researchers have discovered cheaper and more efficient materials for producing hydrogen for the storage of renewable energy that could replace current water-splitting catalysts.
Professor Anthony O’Mullane said the potential for the chemical storage of renewable energy in the form of hydrogen was being investigated around the world.
“The Australian Government is interested in developing a hydrogen export industry to export our abundant renewable energy,” said Professor O’Mullane from QUT’s Science and Engineering Faculty.

Anglo-Saxon burial site shines a light on the high worth of women in the Dark Ages
The emancipation of women is generally considered a modern phenomenon, but a new burial site in Lincolnshire has shown that females were already enjoying high social status, wealth and power in their own right during the Dark Ages.
Archaeologists at the University of Sheffield discovered 20 burials at a cemetery in Scremby, on the southern edge of the Lincolnshire wolds, dating back to the late fifth to mid sixth centuries AD. Around half the graves were females, who were found to be richly dressed and surrounded by riches including amber necklaces, hundreds of glass beads, silver buckles and ivory clasps.

Light-activated, single-ion catalyst breaks down carbon dioxide
A team of scientists has discovered a single-site, visible-light-activated catalyst that converts carbon dioxide (CO2) into “building block” molecules that could be used for creating useful chemicals. The discovery opens the possibility of using sunlight to turn a greenhouse gas into hydrocarbon fuels.

Improbable Thruster Seems to Work by Violating Known Laws of Physics
Every action creates an equal and opposite reaction. It’s perhaps the best known law of physics, and Guido Fetta thinks he’s found a way around it.
According to classical physics, in order for something—like a spaceship—to move, conservation of momentum requires that it has to exert a force on something else. A person in roller skates, for example, pushes off against a wall; a rocket accelerates upward by propelling high-velocity combusted fuel downward. In practice, this means that space vessels like satellites and space stations have to carry up to half their weight in propellant just to stay in orbit. That bulks up their cost and reduces their useful lifetime.
