Exclusive: Pope says he could accept more resignations over Chile sex abuse

Exclusive: Pope says he could accept more resignations over Chile sex abuseBy Philip Pullella VATICAN CITY (Reuters) – Pope Francis has said he could accept the resignations of more Chilean bishops following a sexual abuse scandal that has shattered the credibility of the Roman Catholic Church in the South American country. The pope has already accepted the resignations of three bishops, and all Chile’s remaining bishops have offered to resign after allegations that the abuse, including of children, was covered up. Asked whether he would accept more resignations, the pontiff said: “Maybe some.” “I still have to accept the resignations of two (bishops) who have exceeded the age limit.

Extreme volcanic eruptions could explain mysterious rock formation on Mars

Extreme volcanic eruptions could explain mysterious rock formation on MarsCould a volcanic eruption be the key to unlocking the mysterious geological history of Mars? Back in the 1960s, NASA's Mariner spacecraft discovered an extremely large and unusually soft rock formation. The makeup of the mass, now known as the Medusa Fossae formation, stumped researchers for decades because they were never able to determine how it got there.  SEE ALSO: Tiny NASA satellite bound for Mars snaps photo of Earth from thousands of miles away But now, new research seems to answer that question — and maybe many others.  More than 3 billion years ago, extreme volcanic eruptions on Mars dropped the huge deposit near the Martian equator, according to the new study published in the
Journal of Geophysical Research: Planets.

Ojha and his colleagues used gravity data from spacecraft orbiting Mars to measure the formation density. Through this, they were able to determine that the rock was unusually porous, allowing them to rule out other potential compositions like ice.  On a basic level, the formation is a bunch of hills and mounds of sedimentary rock but because much of Mars’s history is shrouded in mystery, a finding like this is huge.  An isolated hill in the Medusae Fossae Formation.

A considerable amount of “climate-altering” gases like hydrogen sulfide and sulfur dioxide accompany most volcanic eruptions and would have spit out enough water to cover the red planet in a global ocean, the study says.  These findings paint a better picture of what habitability on Mars would look like, as well as the usefulness of gravity surveys.  “Future gravity surveys could help distinguish between ice, sediments and igneous rocks in the upper crust of the planet,” co-author and planetary scientist Kevin Lewis explained.   WATCH: NASA is attempting to fly a helicopter on Mars for the first time

Iran could unleash new refugee wave, Netanyahu tells Berlin

Iran could unleash new refugee wave, Netanyahu tells BerlinIran’s activities across the Middle East threaten to drive another wave of refugees to Europe, Israeli Prime Minister Benjamin Netanyahu said after talks with German Chancellor Angela Merkel on Monday. Netanyahu, on a tour to persuade European countries to follow the U.S. administration of Donald Trump in tearing up a nuclear non-proliferation deal with Iran, said the country was using proceeds from eased sanctions to finance conflict. Iran wanted to expand and deploy Shi’ite militias it commanded to convert Muslims from the Sunni branch of Islam, he said at a joint news conference with Merkel.

How the Moon's movements could give us Earthlings a 25-hour day

How the Moon's movements could give us Earthlings a 25-hour dayMany of us feel as if there are not quite enough hours in a day – but according to scientists, this could change in the future. Researchers have found that the effect of the Moon moving away from Earth causes our planet to spin more slowly, lengthening the day. A new study, published today in Proceedings of the National Academy of Sciences, shows that 1.4 billion years ago, a day on Earth lasted just over 18 hours. This is at least in part because the moon was closer and changed the way Earth spun around its axis. The moon is currently moving away from Earth at a rate of 3.82cm a year, which could mean in around 200 million years’ time, each day will be 25 hours long. Stephen Meyers, a professor of geoscience at the University of Wisconsin-Madison and co-author of the study, explained: “As the Moon moves away, the Earth is like a spinning figure skater who slows down as they stretch their arms out.”  This is because Earth’s movement is at least in part determined by the bodies around it, such as other planets and the Moon, which exert force on it.  How our days on Earth are getting longer Changes in this force can effect changes in the orbit Earth traces around the Sun as well as its rotation around and wobble on its axis. These variations, called Milankovich cycles, determine where sunlight is distributed on Earth, and so decide the planet’s climate rhythms.  These rhythms can be detected in the rock record, spanning hundreds of millions of years. Over billions of years, time has changed significantly on Earth, because the Solar System has many moving parts, including the other planets orbiting the Sun. Changes in the rock record can show changes in Earth’s rotation and allow scientists to map how it moved over time.  However, going back billions of years has previously proven difficult as most scientific methods do not give the precision needed for such a leap back in time. Over billions of years, time has changed significantly on Earth, because the Solar System has many moving parts, including the other planets orbiting the Sun Credit: NASA This groundbreaking new study used astrochronology, a statistical method that links astronomical theory with geological observation, to discover ancient  climate change and reconstruct the history of the Solar System while looking back on Earth’s geologic past. “One of our ambitions was to use astrochronology to tell time in the most distant past, to develop very ancient geological time scales,” Dr Meyers said. “We want to be able to study rocks that are billions of years old in a way that is comparable to how we study modern geologic processes.” Alberto Malinverno, Lamont research professor at Columbia, joined the project after hearing Dr Meyers  speaking about his work at a conference. The two combined a statistical method that Meyers developed in 2015 to deal with uncertainty across time, called TimeOpt, with astronomical theory, geologic data and a sophisticated statistical approach called Bayesian inversion. This combination of methods allowed the pair to reliably assess the direction of the axis of rotation of Earth, and the shape of its orbit, from testing layers of rock in the 1.4 billion-year-old Xiamaling Formation from Northern China and a 55 million-year-old record from Walvis Ridge, in the southern Atlantic Ocean. From this, they could determine the length of day and the distance between Earth and the Moon. Dr Malinverno explained: “In the future, we want to expand the work into different intervals of geologic time.”
