Theories on how the Milky Way formed are set to be rewritten following discoveries about the behavior of some of its oldest stars.

An investigation into the orbits of the Galaxy’s metal-poor stars—assumed to be among the most ancient in existence—has found that some of them travel in previously unpredicted patterns.

“Metal-poor stars—containing less than one-thousandth the amount of iron found in the Sun—are some of the rarest objects in the galaxy,” said Professor Gary Da Costa from Australia’s ARC Center of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D) and the Australian National University.

When we apprehend reality as the entirety of everything that exists including all dimensionality, all events and entities in their respective timelines, then by definition nothing exists outside of reality, not even “nothing.” It means that the first cause for reality’s existence must lie within ontological reality itself, since there is nothing outside of it. This self-causation of reality is perhaps best understood in relation to the existence of your own mind. Self-simulated reality transpires as self-evident when you relate to the notion that a phenomenal mind, which is a web of patterns, conceives a certain novel pattern and simultaneously perceives it. Furthermore, the imminent natural God of Spinoza, or Absolute Consciousness, becomes intelligible by applying a scientific tool of extrapolation to the meta-systemic phenomenon of radical emergence and treating consciousness as a primary ontological mover, the Source if you will, not a by-product of material interactions.

When and how did the first animals appear? Science has long sought an answer to this question. Uppsala University researchers and colleagues in Denmark have now jointly found, in Greenland, embryo-like microfossils up to 570 million years old, revealing that organisms of this type were dispersed throughout the world. The study is published in Communications Biology.

“We believe this discovery of ours improves our scope for understanding the period in Earth’s history when animals first appeared—and is likely to prompt many interesting discussions,” says Sebastian Willman, the study’s first author and a palaeontologist at Uppsala University.

The existence of animals on Earth around 540 million years ago (mya) is well substantiated. This was when the event in evolution known as the “Cambrian Explosion” took place. Fossils from a huge number of creatures from the Cambrian period, many of them shelled, exist. The first animals must have evolved earlier still; but there are divergent views in the research community on whether the extant fossils dating back to the Precambrian Era are genuinely classifiable as animals.

Some scientists believe that the ability of animals to store memory came from a virus that infected a common ancestor hundreds of millions of years ago. 😃

This study is radically changing how we view the process of evolution.

The great powerful guppy can essentially evolve 10 million times faster than usual. Which could lead to humans evolving faster too leading to a biological singularity.

Although natural selection is often viewed as a slow pruning process, a dramatic new field study suggests it can sometimes shape a population as fast as a chain saw can rip through a sapling. Scientists have found that guppies moved to a predator-free environment adapted to it in a mere 4 years—a rate of change some 10,000 to 10 million times faster than the average rates gleaned from the fossil record. Some experts argue that the 11-year study, described in today’s issue of Science,* may even shed light on evolutionary patterns that occur over eons.

A team led by evolutionary biologist David Reznick of the University of California, Riverside, scooped guppies from a waterfall pool brimming with predators in Trinidad’s Aripo River, then released them in a tributary where only one enemy species lurked. In as little as 4 years, male guppies in the predator-free tributary were already detectably larger and older at maturity when compared with the control population; 7 years later females were too. Guppies in the safer waters also lived longer and had fewer and bigger offspring.

Chemists studying how life started often focus on how modern biopolymers like peptides and nucleic acids contributed, but modern biopolymers don’t form easily without help from living organisms. A possible solution to this paradox is that life started using different components, and many non-biological chemicals were likely abundant in the environment. A new survey conducted by an international team of chemists from the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology and other institutes from Malaysia, the Czech Republic, the U.S. and India, has found that a diverse set of such compounds easily form polymers under primitive environmental conditions, and some even spontaneously form cell-like structures.

Understanding how life started on Earth is one of the most challenging questions modern science seeks to explain. Scientists presently study modern organisms and try to see what aspects of their biochemistry are universal, and thus were probably present in the organisms from which they descended. The best guess is that life has thrived on Earth for at least 3.5 billion of Earth’s 4.5-billion-year history since the planet formed, and most scientists would say life likely began before there is good evidence for its existence. Problematically, since Earth’s surface is dynamic, the earliest traces of life on Earth have not been preserved in the geological record. However, the earliest evidence for life on Earth tells us little about what the earliest organisms were made of, or what was going on inside their cells. “There is clearly a lot left to learn from prebiotic chemistry about how life may have arisen,” says the study’s co-author Jim Cleaves.

A hallmark of life is evolution, and the mechanisms of evolution suggest that common traits can suddenly be displaced by rare and novel mutations which allow mutant organisms to survive better and proliferate, often replacing previously common organisms very rapidly. Paleontological, ecological and laboratory evidence suggests this occurs commonly and quickly. One example is an invasive organism like the dandelion, which was introduced to the Americas from Europe and is now a commo weed causing lawn-concerned homeowners to spend countless hours of effort and dollars to eradicate.

Scientists today are quick to point out that they are still basing their models on life as we know it: Carbon-based and reliant on organic compounds and water…

In 2001, the first author (S.N.) led the publication of a book entitled “Geochemistry and the origin of life” in collaboration with Dr. Andre Brack aiming to figure out geo- and astro-chemical processes essential for the emergence of life. Since then, a great number of research progress has been achieved in the relevant topics from our group and others, ranging from the extraterrestrial inputs of life’s building blocks, the chemical evolution on Earth with the aid of mineral catalysts, to the fossilized records of ancient microorganisms. Here, in addition to summarizing these findings for the origin and early evolution of life, we propose a new hypothesis for the generation and co-evolution of photosynthesis with the redox and photochemical conditions on the Earth’s surface. Besides these bottom-up approaches, we introduce an experimental study on the role of water molecules in the life’s function, focusing on the transition from live, dormant, and dead states through dehydration/hydration. Further spectroscopic studies on the hydrogen bonding behaviors of water molecules in living cells will provide important clues to solve the complex nature of life.

Summary: Study reveals a new role for serotonin in the development of the human neocortex. Serotonin acts cell-extrinsically as a growth factor for basal progenitors in the developing neocortex. Researchers report placenta-driven serotonin likely contributed to the evolutionary expansion of the neocortex in humans.

During human evolution, the size of the brain increased, especially in a particular part called the neocortex. The neocortex enables us to speak, dream and think. In search of the causes underlying neocortex expansion, researchers at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, together with colleagues at the University Hospital Carl Gustav Carus Dresden, previously identified a number of molecular players. These players typically act cell-intrinsically in the so-called basal progenitors, the stem cells in the developing neocortex with a pivotal role in its expansion.
