A new study has examined how future human missions to Mars could access one of the planet’s most vital resources—water. The “Martian aqua: occurrence of water and appraisal of acquisition technologies” paper, published in the Advances in Space Research journal, presents a comparative analysis of potential water acquisition technologies for use on the red planet. It also evaluates the feasibility of extracting water from various Martian sources, including underground ice, soil moisture, and atmospheric vapor—building on the findings of earlier studies which identified the sources.
Space debris—the thousands of pieces of human-made objects abandoned in Earth’s orbit—pose a risk to humans when they fall to the ground. To locate possible crash sites, a Johns Hopkins University scientist has helped to devise a way to track falling debris using existing networks of earthquake-detecting seismometers.
In inertial confinement fusion, a capsule of fuel begins at temperatures near zero and pressures close to vacuum. When lasers compress that fuel to trigger fusion, the material heats up to millions of degrees and reaches pressures similar to the core of the sun. That process happens within a miniscule amount of space and time.
Physicists have used a new optical centrifuge to control the rotation of molecules suspended in liquid helium nano-droplets, bringing them a step closer to demystifying the behavior of exotic, frictionless superfluids.
Scientists analyzing data from heavy ion collisions at the Large Hadron Collider (LHC)—the world’s most powerful particle collider, located at CERN, the European Organization for Nuclear Research—have new evidence that a pattern of “flow” observed in particles streaming from these collisions reflects those particles’ collective behavior. The measurements reveal how the distribution of particles is driven by pressure gradients generated by the extreme conditions in these collisions, which mimic what the universe was like just after the Big Bang.
Researchers have reported new experimental results addressing the origin of rare proton-rich isotopes heavier than iron, called p-nuclei. Led by Artemis Tsantiri, then-graduate student at the Facility for Rare Isotope Beams (FRIB) and current postdoctoral fellow at the University of Regina in Canada, the study presents the first rare isotope beam measurement of proton capture on arsenic-73 to produce selenium-74, providing new constraints on how the lightest p-nucleus is formed and destroyed in the cosmos.
Researchers at the University of Basel and the Laboratoire Kastler Brossel have demonstrated how quantum mechanical entanglement can be used to measure several physical parameters simultaneously with greater precision.

They would later be associated with Elven or Fairy Folk, but in Irish myths, they weren’t anything like the fairies of folklore today. This tribe was not human but described as elegant, beautiful, and even shining with light. These mysterious beings arrived with the secret knowledge of the gods. When you begin to look into their story, you begin to see a dizzying array of connections to ancient mythologies in other parts of the world. These demi-gods arrived on ships descending from the heavens in a great mist that blocked out daylight for three days and nights. Then, they burned the ships, forcing themselves to take up residence permanently. Tuatha Dé Danann is translated to “people of the goddess Danu,” a primordial mother goddess. This same name, Danu, or Asura is also a Hindu goddess, and the name may describe “primeval waters.” Some have drawn comparisons to the wife of Zeus, the goddess Diana, whose name was derived from the Proto-Indo-European for “(bright) sky.” She was known to the Romans as the goddess of the hunt, the Moon, and nature. ![]() According to Mysterious Universe, there are also startling links to many other ancient mythologies, including the Nephilim of the Bible and the ancient Sumerian Anunnaki.
More about the goddess Danu and connections to the Rigveda, the oldest of the sacred books of Hinduism The Tuatha, described as having red hair and green or blue eyes, had superhuman abilities and skills. Ancient astronaut theorists believe this is an example of advanced extraterrestrial technology.

However, some of the Fomorian resembled and intermarried with the Tuatha. In the Leabhar Gabhála Éireann, also called The Book of Invasions, the Fomhoire are identified as “descendants of Cain or of Noah’s unfilial son Ham.” In subsequent victorious wars with the Fomhoire and the half-Fomorian Breas, who for a time ruled the Tuatha, a young hero named Lugh became the King of Ireland. When we look at the deity called Lugh, we see more biblical references as well as connections to other mythologies in Europe. King Lugh, the Celtic Lord of Light, is said to be a youthful sun, storm, or sky god, leads the Tuatha against the Fomorians, defeating his grandfather, the giant cyclops leader Balor. At the second Battle of Mag Tuired, he defeats Balor with a sling, which brings to mind the story of David and Goliath in the Bible. Lugh is also said to have a companion hound named Fáil Inis, whose pelt could turn the water it touched into wine. YouTube Video Here: https://www.youtube.com/watch?v=AN8QqN6Lxkw According to Patheos, Lugh was once widely known throughout Europe.
Lugh’s name, it has been noted, bears similarity to the linguistic roots of the name, Lucifer.
Although the Tuatha Dé Danann prevailed for a time, they lost to another invader, called the Melesians. These peoples, now thought to be the Celts possibly, forced the defeated Tuatha to go underground. According to the mythology, the Tuatha Dé Danann lived in an underground world that could only be accessed through portals. These gateways are thought to be found at megalithic structures and hills. The Tuatha Dé Danann, once considered gods and goddesses, would be relegated to the standing of mythological fairies and fairy circles. While still respected and feared by many in the Irish countryside as real and dangerous beings, they became the stuff of modern fairytales to most people. Although the legend of these gods and goddesses was all but lost to history, today’s interest in the Tuatha Dé Danann is coming back. Ancient astronaut theorists see telltale signs of them in stories of the Druids, in strange megalithic structures found around the world, and even in the stories of giants by Native Americans. Those giants were sometimes said to have red hair but appeared at vast distances from Ireland and well before the known arrival of Europeans in North America. On Season 14, Episode 7, The Druid Connection, you can find out more about the Tuatha Dé Danann, the Druids, and bizarre connections to events in North America.

YouTube Video Here: https://www.youtube.com/embed/a2744xoqRKo?feature=oembed&enablejsapi=1 When we think of woolly mammoths, we think of creatures that walked the Earth tens of thousands of years ago before the entire species became extinct due to the warming of the planet. But a new study shows that not all of them perished this early, and scientists are narrowing down why the last group died out. The last mammoths survived on Wrangel Island until just 4,000 years ago after previous domination of the landscape for 90,000 years. In fact, the last mammoths died not long after the ancient Egyptians built the pyramids. (according to conventional dating) That in itself is a wild bit of trivia. The question is how did they die?![]() Wrangel Island was cut off from the Siberian mainland several thousand years ago due to rising sea levels, thus isolating a group of mammoths and preserving them for thousands of years more than they otherwise would have survived. ![]() Located just east of Alaska and North of Russia in the Arctic Ocean, Wrangel Island was somehow spared from the effects of climate change, giving the mammoths a refuge. But then they suddenly vanished 4,000 years ago, leaving their bones scattered across the island, where they can still be seen today. ![]() ![]() A team of scientists from Finland, Germany, and Russia wanted to know why these mammoths died out so quickly after having survived thousands of years longer than the rest of their species on an island that could have maintained them into the present day. So, they gathered bone specimens such as tusks and teeth and performed genetic testing to get answers. What they found is nothing short of fascinating, yet tragic, and contradicts existing theories. ![]() According to the study as published by Quaternary Science Reviews: “Contrary to prior suggestions of gradual habitat deterioration, the nitrogen isotope values of the Wrangel Island mammoths do not support a decline in forage quality/quantity, and are in fact very similar to their north Beringian forebears right to the end. However, compared to Siberian mammoths, those from Wrangel Island show a difference in their energy economy as judged by the carbon isotope values of structural carbonate, possibly representing a lower need of adaptive strategies for survival in extreme cold. Increased mid-Holocene weathering of rock formations in the central mountains is suggested by sulfur isotope values. Scenarios related to water quality problems stemming from increased weathering, and a possibility of a catastrophic starvation event as a cause of, or contributing factor in their demise.”
![]() The researchers found that the environment of Wrangel Island remained appropriate for mammoth survival despite a warming climate, but that still doesn’t rule out other factors.
Just 1,600 years earlier, a similar group of mammoths stranded on a smaller island in the Bering Sea died out because of worsening water quality. The same fate could have been suffered by the mammoths on the much larger Wrangel Island.
![]() It’s also possible that a severe winter contributed to the demise of the mammoths, something that we still see today in living species who live in colder climates.
![]() “We think this reflects the tendency of Siberian mammoths to rely on their reserves of fat to survive through the extremely harsh ice age winters, while Wrangel mammoths, living in milder conditions, simply didn’t need to,” Arppe said in a statement. But the team also found evidence of toxic metals in the remains, which could have been ingested when the animals drank water. Even a little warming could have exposed certain rocks to water flow that eroded the toxic metals into the freshwater supply. Furthermore, the testing revealed inbreeding among the mammoth population, which would have carried significant genetic mutations that rendered the mammoths more vulnerable to a number of things that could have killed them.
More from the Natural History Museum And so, the mammoths passed into history a whole lot later than we previously believed, but while the scientists have narrowed down the list of possible causes of their demise, they have not found the smoking gun identifying an exact cause of death.
It should be pointed out that evidence of humans on Wrangel Island dates back to a few hundred years after the mammoths had already become extinct, so humans likely played no role. But humans are playing a major role in the current mass extinction of species occurring on our planet today, and this study will help us preserve the species that still live.
Any help we can get to aid in our effort to prevent mass extinctions is certainly welcome. It’s too late for mammoths, but it’s not too late for many species, including the elephant, a relative of the mammoth. If they go extinct as well, the mammoth will truly be lost forever.
