Does the Mysterious Big Void in the Great Pyramid hold a Throne made from Extraterrestrial Metal?

Last November, the Scan Pyramids project unveiled evidence that there is a 30-meter (100-foot) chamber running above the Grand Gallery in the Great Pyramid at Giza. The image of the chamber, produced by muon tomography (basically an x-ray of the pyramid, made using cosmic rays), is unfortunately imprecise, leading to a wide variety of ideas and speculation as to the chamber's function and what may lie within. One such idea has been put forward by a Italian astrophysicist/archaeoastronomer Giulio Magli, in that it may contain an iron throne for the pharaoh to sit upon, as part of his journey into the afterlife.

Who are We and Why are We Here?

January 19, 2018
What is consciousness and why does it matter whether or not we know? The truth is that our most basic understanding of who we are and what our fate may be depends on the answers to those two questions, and in this week's show Ervin Laszlo, one of the great thinkers and philosophers of our time, returns to Dreamland to tell us about the newest research into such things as whether or not consciousness lives only in the brain, and, if it is nonlocal, then what is the meaning of human life and the fate of a human being?

Researchers use AI to Decode Human Thought Patterns

Researchers at Japan's Kyoto University have developed a new artificial intelligence program that can be used to decode human thought patterns, translating brain scans into pictures of not only what the subject is looking at, but also simply remembering, into digital images that can be reviewed.

Detectan una nueva molécula aromática en una gigantesca guardería estelar

Con la ayuda de radiotelescopios, un equipo de astrónomos ha descubierto benzonitrilo en la nube molecular de Tauro, una región de formación de estrellas situada a 450 años luz. El hallazgo ayudará a comprender mejor el papel de sustancias orgánicas aromáticas como esta en la composición de las nuevas estrellas y planetas.

The Hypatia Stone Meteorite may be Older than the Solar System -- or from Somewhere Else Altogether

A new analysis of a small rock called the Hypatia Stone, presumed to be a fragment from a comet, reveals that it might either be from outside the Solar System, or older than the Sun itself.

Discovered in 1996 in the same region of the Eastern Sahara as the odd phenomenon known as Libyan Desert glass, a 2013 analysis of the Hypatia Stone discovered that it was of extraterrestrial origin, and was hypothesized to be a fragment of a cometary nucleus. However, a new analysis has found that the stone's odd atomic composition doesn't even match any known meteorite samples, implying that it is either from outside the Solar System, or it predates the formation of the Solar System itself.

Los viajes cotidianos pueden reducir la incidencia de una epidemia

Investigadores de la Universidad Rovira y Virgili y de la Universidad de Zaragoza han diseñado un modelo matemático que permite hacer predicciones sobre la expansión de enfermedades en situaciones de movilidad recurrente, como los viajes constantes de casa al trabajo. Al contrario de lo que se podría pensar, la movilidad diaria entre distritos reduce la incidencia de propagación de una epidemia.

2017 was the Second Hottest Year on Record, Barely Beating an El Niño-Fueled 2016

Europe's Copernicus Programme has announced that 2017 was the world's second hottest year on record, coming in at only 0.1ºC cooler than 2016's El Niño-influenced record at 1.2ºC (2.2ºF) above pre-industrial levels, with 2017 actually being the hottest year on record for a year that was "not influenced by warming El Niño conditions in the tropical Pacific," according to their report. On top of this, 2017's temperature record occurred "despite cooling La Niña conditions both early and late in the year over the equatorial eastern Pacific Ocean."

Absolute Holism--and What That Means to You

Wednesday January 10, 2018
"Scott" returns to talk about his spiritual theory of everything called "Absolute Holism." But first, we continue our conversation from last episode, delving into the high strangeness and dreamtime experiences that most shook his worldview and led him to rethink reality.

Cybersecurity Flaws 'Meltdown' and 'Spectre' Affect Nearly Every Computer on the Planet

On January 3, a group of cybersecurity experts announced the existence of two security flaws affecting virtually every microprocessor on the planet, codenamed 'Meltdown' and 'Spectre': the Meltdown exploit affects computer processors that were built by Intel over the past decade, used in the majority of consumers' personal computers, and over 90 percent of the world's computer servers; Spectre is somewhat less dangerous, but is more widespread, as it affects not only Intel processors, but also those of their main competitor, Advanced Micro Devices (AMD), and Britain's Advanced RISC Machine (ARM) chips. These vulnerabilities could potentially allow hackers to access personal data from computers, mobile devices, smart TVs, and cloud servers around the world.

Primera medida de las pérdidas de iones rápidos en un tokamak

Miembros del Centro Nacional de Aceleradores, en Sevilla, han cuantificado por primera vez las pérdidas de partículas energéticas o iones rápidos que se producen un reactor tokamak de fusión nuclear. El avance permitirá mejorar la capacidad para realizar predicciones en los futuros reactores de este tipo, como el del experimento ITER que es construye en Francia.

The Beaufort Gyre is stuck in a Clockwise Pattern, Worrying Researchers

The Beaufort Gyre is a wind-driven circular current in the western half of the Arctic Ocean, that alternates between a clockwise and counter-clockwise motion: when it circulates clockwise, it traps ice and melted freshwater, and when it spins counter-clockwise, it releases that freshwater and ice into the North Atlantic Ocean, southward past the east coast of Greenland. This trap-and-release cycle typically reverses every five to seven years, usually when a cyclonic storm in the North Atlantic moves into the Arctic, reversing the Gyre's direction.
