In coming years, scientists plan to grow human embryos in a lab using high-tech artificial wombs.

Doctors at the Children’s Hospital of Philadelphia are in talks with the U.S. Food and Drug Administration (FDA) to begin testing artificial wombs on human embryos within the next two years, according to Metro. If they’re successful, the research could radically change the way we view pregnancy, childbirth, and perhaps even human evolution.

Lawrence Livermore National Laboratory (LLNL) scientists in collaboration with University of Nevada Las Vegas (UNLV) have discovered a previously unknown pressure induced phase transition for TATB that can help predict detonation performance and safety of the explosive. The research appears in the May 13 online edition of the Applied Physics Letters and it is highlighted as a cover and featured article.

1,3,5-Triamino-2,4,6- trinitrobenzene (TATB), the industry standard for an insensitive high explosive, stands out as the optimum choice when safety (insensitivity) is of utmost importance. Among similar materials with comparable explosive energy release, TATB is remarkably difficult to shock-initiate and has a low friction sensitivity. The causes of this unusual behavior are hidden in the high-pressure structural evolution of TATB. Supercomputer simulations of explosives detonating, running on the world’s most powerful machines at LLNL, depend on knowing the exact locations of the atoms in the crystal structure of an explosive. Accurate knowledge of atomic arrangement under pressure is the cornerstone for predicting the detonation performance and safety of an explosive.

The team performed experiments utilizing a diamond anvil cell, which compressed TATB single crystals to a pressure of more than 25 GPa (250,000 times atmospheric pressure). According to all previous experimental and theoretical studies, it was believed that the atomic arrangement in the crystal structure of TATB remains the same under pressure. The project team challenged the consensus in the field aiming to clarify the high-pressure structural behaviour of TATB.

The Aldabra white-throated rail, a flightless bird that lives on its namesake atoll in the Indian Ocean, doesn’t look like anything special at first glance. But the small bird has big bragging rights, because it has effectively evolved into existence twice after first going extinct some 136,000 years ago.

According to a study published Wednesday in the Zoological Journal of the Linnean Society, the rail is an example of a rarely observed phenomenon called iterative evolution, in which the same ancestral lineage produces parallel offshoot species at different points in time. This means that near-identical species can pop up multiple times in different eras and locations, even if past iterations have gone extinct.

Fossils of the flightless bird were found both before and after Albadra was submerged by an “inundation event” that occurred around 136,000 years ago, said study authors Julian Hume, an avian paleontologist at Natural History Museum in London, and David Martill, a paleobiologist at the University of Portsmouth.

Scientists from Trinity College Dublin have discovered a potential new target for regulating inflammation, which drives a range of diseases including diabetes, cancer and Alzheimer’s. The potential target is an ancient immune protein—SARM—that has been conserved throughout evolution and thus is very similar in humans, other mammals, flies and worms.

The scientists, from Trinity’s School of Biochemistry and Immunology based at the Trinity Biomedical Sciences Institute (TBSI), discovered a previously unknown but important role that SARM plays in the immune response. Their work has been published today in the prestigious journal Immunity.

In trying to answer such questions, scientists bump up against the limits of the laws of physics. Existing theories can account for the evolution of the universe from its earliest moments — from a fraction of a second after the Big Bang — but the question of what came before has been among the most vexing in all of science.

“It’s my life’s work to try to answer that question,” University of Toronto physicist Renée Hložek says.

Scientist now have to reevaluate what they know – or thought they knew – about the evolution of millipedes due to a tiny, 8.2-mm member of the order Callipodida who got its many feet stuck in some tree resin, which turned up in Myanmar, 99 million years later, as a golden lump of amber.

Ecstadelic Media Group releases a new non-fiction book The Origins of Us: Evolutionary Emergence and The Omega Point Cosmology by Alex M. Vikoulov as a Kindle ebook (Press Release, San Francisco, CA, USA, April 22, 2019 01.00 PM PST)

The Science and Philosophy of Information book series is adapted for general audience and based on the previously published grand volume titled “ The Syntellect Hypothesis: Five Paradigms of the Mind’s Evolution” by digital philosopher Alex Vikoulov on the ultimate nature of reality, consciousness, the physics of time, and philosophy of mind. In this book one of the series, the author addresses some of the most flaming questions in science and philosophy: Where do we come from? What are the origins of us? What is our role in the grand scheme of things?

“# 1 Hot New Release” in Amazon charts in Cosmology and Evolution, the book starts with a story that happened almost exactly 400 years ago that has had a tremendous “butterfly” effect on us modern humans.

Scientists have used the tiny distortions imprinted on the cosmic microwave background by the gravity of matter throughout the universe, recorded by ESA’s Planck satellite, to uncover the connection between the luminosity of quasars – the bright cores of active galaxies – and the mass of the much larger ‘halos’ of dark matter in which they sit. The result is an important confirmation for our understanding of how galaxies evolve across cosmic history.

Most galaxies in the universe are known to host supermassive black holes, with masses of millions to billions of times the Sun’s mass, at their cores. The majority of these cosmic monsters are ‘dormant’, with little or no activity going on near them, but about one percent are classified as ‘active’, accreting matter from their surroundings at very intense rates. This accretion process causes material in the black hole’s vicinity to shine brightly across the electromagnetic spectrum, making these active galaxies, or quasars, some of the brightest sources in the cosmos.

While it is still unclear what activates these black holes, switching on and off their phase of intense accretion, it is likely that quasars play an important role in regulating the evolution of galaxies across cosmic history. For this reason, it is crucial to understand the relationship between quasars, their host galaxies, and their environment on even larger scales.
