Chicken or Egg? Scientists claim to have found answer to centuries-old puzzle

Posted by in category: evolution

In a new study, the scientists claimed to have found the answer to one of the most baffling questions in the history of humankind — ‘What came first: Chicken or the egg?’. The question has to date left everyone, from scholars to schoolchildren, stumped. However, scientists now claim to have discovered the answer.

As per the researchers from the University of Bristol, the early ancestors of reptiles and modern birds are likely to have given birth to live young and may have not laid eggs, according to The Times. The Journal Nature Ecology and Evolution published the study which detailed the discovery.

Scientists, along with researchers from Nanjing University, have challenged the belief which existed so far that hard-shelled eggs were the reason for the success of amniotes, which are animals whose foetuses are developed inside an amnion (membrane or sack) inside the egg.

Astronomers observe white dwarf star transforming into massive celestial diamond

Posted by in categories: evolution, space

They believe the process could take roughly a quadrillion years.

A team of astronomers discovered a star that is gradually crystallizing into an enormous diamond. Scientists believe it is at the beginning of a process that takes roughly a quadrillion years, a report from Space.com reveals. As the universe is 13.6 billion years old, no star has ever fully crystallized.

The discovery sheds new light on the evolution of stars as they gradually transform over time.

Measurement-induced entanglement phase transition on a superconducting quantum processor with mid-circuit readout

Posted by in categories: evolution, quantum physics

The interplay of quantum measurements and unitary evolution is expected to produce dynamical phases with different entanglement properties. An entanglement phase transition has now been detected with hybrid quantum circuits in a superconducting processor.

Multiple mitogenomes indicate Things Fall Apart with Out of Africa or Asia hypotheses for the phylogeographic evolution of Honey Bees (Apis mellifera)

Posted by in categories: biotech/medical, evolution

Previous morpho-molecular studies of evolutionary relationships within the economically important genus of honey bees (Apis), including the Western Honey Bee (A. mellifera L.), have suggested Out of Africa or Asia origins and subsequent spread to Europe. I test these hypotheses by a meta-analysis of complete mitochondrial DNA coding regions (11.0 kbp) from 22 nominal subspecies represented by 78 individual sequences in A. mellifera. Parsimony, distance, and likelihood analyses identify six nested clades: Things Fall Apart with Out of Africa or Asia hypotheses. Molecular clock-calibrated phylogeographic analysis shows instead a basal origin of A. m. mellifera in Europe ~ 780 Kya, and expansion to Southeast Europe and Asia Minor ~ 720 Kya. Eurasian bees spread southward via a Levantine/Nilotic/Arabian corridor into Africa ~ 540 Kya.

The Grand Canyon, a Cathedral to Time, Is Losing Its River

Posted by in category: evolution

Down beneath the tourist lodges and shops selling keychains and incense, past windswept arroyos and brown valleys speckled with agave, juniper and sagebrush, the rocks of the Grand Canyon seem untethered from time. The oldest ones date back 1.8 billion years, not just eons before humans laid eyes on them, but eons before evolution endowed any organism on this planet with eyes.

Spend long enough in the canyon, and you might start feeling a little unmoored from time yourself. The immense walls form a kind of cocoon, sealing you off from the modern world, with its cell signal and light pollution and disappointments. They draw your eyes relentlessly upward, as in a cathedral.

You might think you are seeing all the way to the top. But up and above are more walls, and above them even more, out of sight except for the occasional glimpse. For the canyon is not just deep. It is broad, too — 18 miles, rim to rim, at its widest. This is no mere cathedral of stone. It is a kingdom: sprawling, self-contained, an alternate reality existing magnificently outside of our own.

Dark matter atoms may form shadowy galaxies with rapid star formation

Posted by in categories: cosmology, evolution, particle physics

Dark matter, the invisible material that makes up the vast majority of the universe’s mass, may collect itself to form atoms, a new simulation shows.

Those “dark atoms” might radically alter the evolution of galaxies and the formation of stars, giving astronomers a new opportunity to understand this mysterious substance.

Timelapse of Future Technology: Next 1000 Years

Posted by in categories: evolution, futurism

Today, we explore a timelapse of the future, specifically future technology. How will technology look 1,000 years from now? In the world today, many technologies are accelerating exponentially. Humans are discovering things that would mystify scientists even a few decades ago, but our progress resembles a blip in the grand scale of our technological evolution over the next millennium.

Is there an infinite universe? According to scientists, our universe has no beginning

Posted by in categories: cosmology, evolution, quantum physics, singularity

The Big Bang, traditionally considered the birth of the universe about 14 billion years ago, is being questioned. Physicist Bruno Bento and his team have proposed compelling research suggesting the universe may have always existed, and the Big Bang may merely be a significant event in its continuous evolution.

Bruno Bento and his colleagues set out to examine what the universe’s inception might have looked like without a Big Bang singularity. They grappled with contradictions arising when comparing accepted theories, particularly those dealing with quantum physics and general relativity. While quantum physics has accurately described three of the four fundamental forces of nature, it struggles to incorporate gravity. On the other hand, general relativity offers a comprehensive explanation of gravity, but falters when dealing with black holes’ centers and the universe’s genesis.

These contentious areas, termed “singularities,” are points in space-time where established physical laws cease to apply. Intriguingly, computations indicate an immense gravitational pull within singularities, even on a minuscule scale.

Intelligence Explosion — Part 2/3

Hallucination!

Can “hallucinations” generate an alternate world, prophesying falsehood?

As I write this article, NVIDIA( is surpassing Wall Street’s expectations. The company, headquartered in Santa Clara, California, has just joined the exclusive club of only five companies in the world valued at over a trillion dollars [Apple (2.7T), Microsoft (2.4T), Saudi Aramco (2T), Alphabet/Google (1.5T), and Amazon (1.2T)], as its shares rose nearly 25% in a single day! A clear sign of how the widespread use of Artificial Intelligence (AI) can dramatically reshape the technology sector.

Intel has announced an ambitious plan to develop scientific generative AIs designed with one trillion parameters. These models will be trained on various types of data, including general texts, code, and scientific information. In comparison, OpenAI’s GPT-3 has 175 billion parameters (the size of GPT-4 has not yet been disclosed by OpenAI). The semiconductor company’s main focus is to apply these AIs in the study of areas such as biology, medicine, climate, cosmology, chemistry, and the development of new materials. To achieve this goal, Intel plans to launch a new supercomputer called Aurora, with processing capacity exceeding two EXAFLOPS(*, later this year.
