New research offers a theory on how gold, platinum, and other precious metals found their way to shallow pockets within Earth’s mantle.
Scientists at Yale and the Southwest Research Institute (SwRI) say they’ve hit the jackpot with some valuable new information about the story of gold.
It’s a story that begins with violent collisions of large objects in space, continues in a half-melted region of Earth’s mantle, and ends with precious metals finding an unlikely resting spot much closer to the planet’s surface than scientists would have predicted.
The detection of ammonia isotopologues in a brown dwarf by the James Webb Space Telescope.
The James Webb Space Telescope (JWST or Webb) is an orbiting infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope. It covers longer wavelengths of light, with greatly improved sensitivity, allowing it to see inside dust clouds where stars and planetary systems are forming today as well as looking further back in time to observe the first galaxies that formed in the early universe.
Generation of nearly deterministic OAM-based entangled states offers a bridge between photonic technologies for quantum advancements.
Quantum technology’s future rests on the exploitation of fascinating quantum mechanics concepts — such as high-dimensional quantum states. Think of these as states basic ingredients of quantum information science and quantum tech. To manipulate these states, scientists have turned to light, specifically a property called orbital angular momentum (OAM), which deals with how light twists and turns in space. Here’s a catch: making super bright single photons with OAM in a deterministic fashion has been a tough nut to crack.
Quantum Dots: Bridging Technologies
A team of materials scientists at Songshan Lake Materials Laboratory, working with colleagues from the China Academy of Space Technology and the Chinese Academy of Sciences, all in China, has found that billions of years of exposure to radiation has made glass on the moon harder.
In their paper published in the journal Science Advances, the group describes how they tested samples of lunar regolith brought to Earth by China’s Chang’e-5 lunar lander and then treated the samples to rejuvenate them for comparison purposes.
Humans have been making glass for approximately 4,000 years; nature, on the other hand, has been doing it for billions of years. In this new effort, the research team studied glass that has been made naturally on the moon by meteoroids striking, and melting lunar regolith —some of it billions of years old.
Humane’s AI Pin up close

We spent 90 minutes with the pin and its founders at Humane’s SF offices.
A few hours after this morning’s big unveil, Humane opened its doors to a handful of press.
A few hours after this morning’s big unveil, Humane opened its doors to a handful of press. Located in a nondescript building in San Francisco’s SoMa neighborhood, the office is home to the startup’s hardware design teams.
An office next door houses Humane’s product engineers, while the electrical engineering team operates out of a third space directly across the street. The company also operates an office in New York, though the lion’s share of the 250-person staff are located here in San Francisco.
SpaceX has achieved a world record by delivering over 1,000 metric tons of mass to orbit this year, as its founder Elon Musk claimed.

The mission was launched by a Falcon 9 rocket from Vandenberg Space Force Base in California at 10:49 am local time (1:49 pm EST; 1,849 GMT). The rocket’s first stage returned to the launch site and landed vertically about 7.5 minutes later. This was the 12th flight and recovery for this booster, per SpaceX’s mission details.
James Webb Space Telescope
Posted in engineering, space
The most powerful telescope ever built.
The James Webb Space Telescope (JWST) is a space telescope that has been designed to study the universe in infrared light. It is the largest and most powerful telescope ever built, and it is the successor to the Hubble Space Telescope.
JWST was launched on December 25, 2021, and it is now operational. The telescope is located at the second Lagrange point (L2) of the Sun-Earth system, which is about 1.5 million kilometers (930,000 miles) from Earth.

In 2015, the Laser Interferometer Gravitational-Wave Observatory, or LIGO
The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory supported by the National Science Foundation and operated by Caltech and MIT. It’s designed to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool. It’s multi-kilometer-scale gravitational wave detectors use laser interferometry to measure the minute ripples in space-time caused by passing gravitational waves. It consists of two widely separated interferometers within the United States—one in Hanford, Washington and the other in Livingston, Louisiana.
