Scientists say a shipwreck off Patagonia is a long-lost 1850s Rhode Island whaler      (via sciencedaily.com) 

Scientists investigating the remains of an old wooden ship off the cold, windy coast of far southern Argentina say it almost certainly is the Dolphin, a globe-trotting whaling ship from Warren, R.I., lost in 1859. Archaeologists have spent years researching the ship's origin without making a definitive identification, but a new analysis of tree rings in its timbers has provided perhaps the most compelling evidence yet.

Analysis of everyday tools challenges long-held ideas about what drove major changes in ancient Greek society      (via sciencedaily.com) 

A modern scientific analysis of ancient stone tools is challenging long-held beliefs about what caused radical change on the island of Crete, where the first European state flourished during the Bronze Age: the 'Minoan civilization.'

NASA schedules PUNCH mission to launch in 2025      (via sciencedaily.com) 

More than 60 engineers and scientists are gathering at Southwest Research Institute Aug. 23-24 to kick off the launch vehicle collaboration for NASA's Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission. PUNCH, which will study the inception of the solar wind, has secured its ride into Earth orbit aboard a SpaceX Falcon 9, sharing a ride into space with NASA's Spectro-Photometer for the History of the Universe, Epoch of Re-ionization, and Ices Explorer (SPHEREx) mission.

Saturn V was loud but didn't melt concrete      (via sciencedaily.com) 

Abundant internet claims about the acoustic power of the Saturn V suggest that it melted concrete and lit grass on fire over a mile away, but such ideas are undeniably false. Researchers used a physics-based model to estimate the rocket's acoustic levels and obtained a value of 203 decibels, which matched the limited data from the 1960s. So, while the Saturn V was extremely loud, that kind of power is nowhere near enough to melt concrete or start grass fires.

Medieval monks were 'riddled with parasites'      (via sciencedaily.com) 

Research examining traces of parasites in medieval Cambridge residents suggests that monks were almost twice as likely as ordinary townspeople to have intestinal worms -- despite monasteries of the period typically having far more sanitary facilities.

Breaking in a new planet      (via sciencedaily.com) 

Impacts affect the porosity and structure of moons and planets more dramatically than scientists suspected, increasing their potential habitability for life. Studying how those impacts affect planetary bodies, asteroids, moons and other rocks in space helps planetary scientists understand extraplanetary geology, especially where to look for precious matter including water, ice and even, potentially, microbial life.

Mars model provides method for landing humans on Red Planet      (via sciencedaily.com) 

A mathematical model developed by space medicine experts could be used to predict whether an astronaut can safely travel to Mars and fulfill their mission duties upon stepping foot on the Red Planet.

Harvesting resources on Mars with plasmas      (via sciencedaily.com) 

Researchers have devised a plasma-based way to produce and separate oxygen within the Martian environment. It's a complementary approach to NASA's Mars Oxygen In-Situ Resource Utilization Experiment and may deliver high rates of molecule production per kilogram of instrumentation sent to space. The team presents the method for harnessing and processing local resources to generate products on Mars.

Hubble sees red supergiant star Betelgeuse slowly recovering after blowing its top      (via sciencedaily.com) 

The star Betelgeuse appears as a brilliant, ruby-red, twinkling spot of light in the upper right shoulder of the winter constellation Orion the Hunter. But when viewed close up, astronomers know it as a seething monster with a 400-day-long heartbeat of regular pulsations. This aging star is classified as a supergiant because it has swelled up to an astonishing diameter of approximately 1 billion miles. If placed at the center of our solar system it would reach out to the orbit of Jupiter. The star's ultimate fate is to explode as a supernova.

One more clue to the Moon's origin      (via sciencedaily.com) 

Researchers discover the first definitive proof that the Moon inherited indigenous noble gases from the Earth's mantle. The discovery represents a significant piece of the puzzle towards understanding how the Moon and, potentially, the Earth and other celestial bodies were formed.

Evidence that giant meteorite impacts created the continents      (via sciencedaily.com)     Original source 

New research has provided the strongest evidence yet that Earth's continents were formed by giant meteorite impacts that were particularly prevalent during the first billion years or so of our planet's four-and-a-half-billion year history.

Planet formation: ALMA detects gas in a circumplanetary disk      (via sciencedaily.com) 

Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study planet formation have made the first-ever detection of gas in a circumplanetary disk. What's more, the detection also suggests the presence of a very young exoplanet.

Octopus lures from the Mariana Islands found to be oldest in the world      (via sciencedaily.com) 

An archaeological study has determined that cowrie-shell artifacts found throughout the Mariana Islands were lures used for hunting octopuses and that the devices, similar versions of which have been found on islands across the Pacific, are the oldest known artifacts of their kind in the world.

Oldest DNA from domesticated American horse lends credence to shipwreck folklore      (via sciencedaily.com) 

Feral horses have roamed freely across the island of Assateague off the coast of Maryland and Virginia for hundreds of years, but exactly how they got there has remained a mystery. In a new study, ancient DNA extracted from a 16th century cow tooth from one of Spain's first Caribbean colonies turns out to be from a horse. Analysis of the DNA suggest that old folk tales claiming that horses were marooned on Assateague following the shipwreck of a Spanish galleon are likely more fact than fiction.

Scientists discover places on the moon where it's always 'sweater weather'      (via sciencedaily.com) 

A team led by planetary scientists has discovered shady locations within pits on the moon that always hover around a comfortable 63 degrees Fahrenheit. The pits, and caves to which they may lead, would make safer, more thermally stable base camps for lunar exploration and long-term habitation than the rest of the moon's surface, which heats up to 260 degrees during the day and drops to 280 degrees below zero at night.
