LCARS is the fictional computer operating system used by Starfleet starships in several Star Trek TV shows and films. The system is currently displayed in the animated comedy Trek series Lower Decks. Now, one intrepid fan has adapted the Lower Decks version of LCARS into a “crazy fan project:” Project RITOS.

RITOS is a webpage that recreates the LCARS system. It’s a fun little site to poke around on. But, since this is just a recreation, there’s no actual functionality you can incorporate onto your computer. As the RITOS About page states, you just “point & click & watch. There are no goals nor wrong thing to do here. It’s just a mindless site.”

It may be mindless, but it’s also a faithful recreation of the LCARS system as depicted not just in Star Trek: Lower Decks but also in The Next Generation, Deep Space Nine, and Voyager. Users can click around into various displays that show crew quarters, a ship map of the Cerritos (the Federation starship in Lower Decks), JWST (James Webb Space Telescope) images, and a Sick Bay screen. There are plenty of fun things to click on and little easter eggs to uncover for dedicated Trek fans.

Leading scientists in the field predict that lithium niobate chips, which are extremely thin, will surpass silicon chips in light-based technologies. These chips have a wide range of potential applications, from detecting ripe fruit from a distance on Earth to guiding navigation on the Moon.

According to the scientists, the artificial crystal of lithium niobate is the preferred platform for these technologies because of its superior performance and advancements in manufacturing techniques.

RMIT University’s Distinguished Professor Arnan Mitchell and University of Adelaide’s Dr. Andy Boes led this team of global experts to review lithium niobate’s capabilities and potential applications in the journal Science.

Two neutron stars collided which caused a huge explosion but with an unusually flawless form, baffling scientists. Usually, a collision between neutron stars would lead to a flattened cloud but the recently observed explosion formed a perfectly spherical shape, SpaceAcademy.org reports.

It is still unclear how this is possible, but a new study may shed light on the fundamental physics involved and help scientists calculate the universe’s age. Astrophysicists from the Universe of Copenhagen discovered the kilonova and described it in full in their study, titled “Spherical Symmetry in the Kilonova At2017gfo/GW170817,” which was published in the journal Nature.

Scientists could finally send more powerful mirrors to space to hunt for exoplanets.

Scientists have found a way to bring bigger telescope mirrors into space, potentially allowing for more exoplanet discoveries.

This is NOT for ChatGPT, but instead its the AI tech used in beating GO, Chess, DOTA, etc. In other words, not just generating the next best word based on reading billions of sentences, but planning out actions to beat real game opponents (and winning.) And it’s free.

Reinforcement learning is an area of machine learning that involves taking right action to maximize reward in a particular situation. In this full tutorial course, you will get a solid foundation in reinforcement learning core topics.

The Planck Temperature – Absolute Hot: What is the hottest temperature possible.

Today I’m going to look at the Planck Temperature and it’s about to get very strange. Let’s find out more.

To study how stars and planets are born we have to look at star cradles hidden in cool clouds of dust. Far-infrared telescopes are able to pierce through those clouds. Conventionally, niobium nitride bolometers are used as the detectors, despite their low operating temperature of 4 Kelvin (−269° Celsius).

Now Yuner Gan (SRON/RUG), together with a team of scientists at SRON, TU Delft, Chalmers University and RUG, has developed a new type of bolometer, made of magnesium diboride, with an operating temperature of 20 Kelvin or above. This can significantly reduce the cost, complexity, weight and volume of the space instruments.

Conventional, superconducting niobium nitride (NbN) hot electron bolometers (HEBs) are so far the most sensitive heterodyne detectors for high-resolution spectroscopy at far-infrared frequencies. Heterodyne detectors take advantage of a local oscillator to convert a terahertz line into a gigahertz line.

Gas clouds in the Cygnus X Region, a region where stars form, are composed of a dense core of molecular hydrogen (H₂) and an atomic shell. These ensembles of clouds interact with each other dynamically in order to quickly form new stars. That is the result of observations conducted by an international team led by scientists at the University of Cologne’s Institute of Astrophysics and at the University of Maryland.

Until now, it was unclear how this process precisely unfolds. The Cygnus X region is a vast luminous cloud of gas and dust approximately 5,000 light years from Earth. Using observations of spectral lines of ionized carbon (CII), the scientists showed that the clouds have formed there over several million years, which is a fast process by astronomical standards. The results of the study, “Ionized carbon as a tracer for the assembly of interstellar clouds,” will appear in the next issue of Nature Astronomy.

The observations were carried out in an international project led by Dr. Nicola Schneider at the University of Cologne and Prof Alexander Tielens at the University of Maryland as part of the FEEDBACK program on board the flying observatory SOFIA (Stratospheric Observatory for Infrared Astronomy). The new findings modify previous perceptions that this specific process of star formation is quasi-static and quite slow. The dynamic formation process now observed would also explain the formation of particularly massive stars.
