Astronomers inspect a powerful radio-loud high-redshift quasar

Posted by in categories: cosmology, evolution

Using the European VLBI Network (EVN), an international team of astronomers has performed high-resolution imaging observations of a powerful and radio-loud high-redshift quasar known as J2102+6015. Results of the observational campaign, presented January 18 on the preprint server arXiv, could help us better understand the nature of this peculiar quasar and other powerful radio sources.

Quasars, or quasi-stellar objects (QSOs), are extremely luminous active galactic nuclei (AGN) containing supermassive central black holes with accretion disks. Their redshifts are measured from the strong spectral lines that dominate their visible and .

Astronomers are especially interested in finding new (at redshift higher than 4.5) as they are the most luminous and most distant compact objects in the observable universe. Spectra of such QSOs can be used to estimate the mass of supermassive black holes that constrain the evolution and formation models of quasars. Therefore, high-redshift quasars could serve as a powerful tool to probe the .

Why can’t we say what cognition is (at least for the time being)

Posted by in category: neuroscience

Some philosophers search for the mark of the cognitive: a set of individually necessary and jointly suΜcient conditions identifying all and only the instances of cognition. They claim the mark is necessary to answer diΜcult questions concerning the nature and distribution of cognition.

Here, I will argue that, as things stand, given the current landscape of cognitive science, we are not able to identify a mark of the cognitive. I proceed as follows. First, I clarify some factors motivating the search for the mark of the cognitive, thereby highlighting the desiderata the mark is supposed to satisfy. Then, I highlight a tension in the literature over the mark. Given the literature, it is not clear whether the search aims for a mark capturing the intuitive notion of cognition or a genuine scientiΞc kind.

Our Universe is normal! Its biggest anomaly, the CMB cold spot, is now explained

Posted by in category: cosmology

The Universe is supposed to be the same everywhere and in all directions. So what’s that giant “cold spot” doing out there?

The Fifth Dimension’s Portal Has Been Found, According to Scientists — archeology and animals Blog

Posted by in categories: cosmology, particle physics

In a new study, scientists say that a particle that links to a fifth dimension can explain dark matter.

The “warped extra dimension” (WED) is a trademark of a popular physics model that was first introduced in 1999. This research, which was published in The European Physical Journal C, is the first to use the theory to explain the long-standing dark matter problem in particle physics. Gravity portals' could morph dark matter into ordinary matter, astrophysicists propose | Live Science

The idea of dark matter, which makes up most of the matter in the universe, is the basis for what we know about how the universe works. Dark matter is like a pinch-hitter that helps scientists figure out how gravity works. Without a “x factor” of dark matter, many things would dissolve or fall apart. Even so, dark matter doesn’t change the particles we can see and “feel,” so it must have other special qualities as well.

Big Tech was moving cautiously on AI. Then came ChatGPT

Posted by in categories: government, robotics/AI, singularity

Welcome to the exponential upward curve phase of the Technological Singularity, folks.

Three months before ChatGPT debuted in November, Facebook’s parent company Meta released a similar chatbot. But unlike the phenomenon that ChatGPT instantly became, with more than a million users in its first five days, Meta’s Blenderbot was boring, said Meta’s chief artificial intelligence scientist, Yann LeCun.

“The reason it was boring was because it was made safe,” LeCun said last week at a forum hosted by AI consulting company Collective[i]. He blamed the tepid public response on Meta being “overly careful about content moderation,” like directing the chatbot to change the subject if a user asked about religion. ChatGPT, on the other hand, will converse about the concept of falsehoods in the Quran, write a prayer for a rabbi to deliver to Congress and compare God to a flyswatter.

Electric vehicles more expensive to fuel than gas-powered cars at end of 2022: consulting firm

Collision review: How CERN’s stellar secrets became sci-fi gold

Posted by in categories: information science, quantum physics

Edited by Rob Appleby and Connie Potter (Comma Press)

IN The Ogre, the Monk and the Maiden, Margaret Drabble’s ingenious story for the new sci-fi anthology Collision, a character called Jaz works on “the interface of language and quantum physics”. Jaz’s speciality is “the speaking of the inexpressible”. Science fiction authors have long grappled with translating cutting-edge research – much of it grounded in what Drabble calls “the Esperanto of Equations” – into everyday language and engaging plots.

Network Neuroscience Theory — The Best Predictor of Intelligence

Posted by in categories: bioengineering, neuroscience, robotics/AI

Researchers have been working for many years to comprehend the relationship between brain structure, functional connectivity, and intelligence. A recent study provides the most comprehensive understanding to date of how different regions of the brain and neural networks contribute to a person’s problem-solving ability in a variety of contexts, a trait known as general intelligence.

The researchers recently published their findings in the journal Human Brain Mapping.

The research, led by Aron Barbey, a professor of psychology, bioengineering, and neuroscience at the University of Illinois Urbana-Champaign, and first author Evan Anderson, a researcher for Ball Aerospace and Technologies Corp. working at the Air Force Research Laboratory, employed the technique of “connectome-based predictive modeling” to evaluate five theories on how the brain leads to intelligence.
