Alpaca AI: Stanford researchers clone ChatGPT AI for just $600

Posted by in categories: futurism, robotics/AI

They have also released the tools needed for people to train their own AI.

Researchers at Stanford’s Center for Research on Foundation Models (CRFM) have unveiled an artificial intelligence (AI) model that works much like the famous ChatGPT but cost them only $600 to train. The researchers said that they hadn’t optimized their process and future models could be trained for lesser.

Until OpenAI’s ChatGPT was launched to the public in November last year, Large Language Models (LLMs) were largely a topic of discussion among AI researchers. The company has spent millions of dollars training them and making sure that they provided responses to human queries in the way another human would respond.

Wearable microscopes show HD images of pain processed

Posted by in categories: neuroscience, wearables

The study authors claim their microscope can provide colored real-time images of hard-to-reach parts of the spinal cord that couldn’t be accessed previously.

Pain is a powerful feeling but have you ever wondered how pain works on a cellular level? Well, a team of scientists at the San Diego-based Salk Insitute has actually figured out a way to see the internal neural mechanism associated with pain.

In their recently published study, they propose wearable microscopes using which they were able to check how nerve cells in the spinal cord of mice process pain signals.

Watch: NASA’s Fermi captures cosmic fireworks invisible to the bare eye

Posted by in categories: energy, space

The animation shows a subset of more than 1,500 light curves collected by the Large Area Telescope over nearly 15 years in space.

NASA has released an intriguing animated video of the sky in gamma rays, the “highest-energy form of light”. Captured by the Large Area Telescope (LAT) aboard NASA’s Fermi Gamma-ray Space Telescope, the animation shows activity during observations from February 2022 to February 2023.

According to a press release, the “pulsing circles represent just a subset of more than 1,500 light curves – records of how sources change in brightness over time – collected by the LAT over nearly 15 years in space”. The LAT detects gamma rays with energies ranging from 20 million to over 300 billion electron volts.

Scientists ‘control’ quantum light for the first time, achieving landmark

Posted by in categories: biotech/medical, computing, quantum physics

“We have taken a vital first step towards harnessing quantum light for practical use.”

Scientists have for the first time shown that they can control and distinguish tiny quantities of interacting photons — or packets of light energy — with high correlation, according to a study published in Nature.

Harnessing quantum light for practical use.

Neutrinos created by CERN Large Hadron Collider detected for the first time

Posted by in categories: particle physics, space

Neutrinos created by LHC went undetected earlier, but FASER changed that and can help us learn more about deep space.

Researchers at the European Organization for Nuclear Research, commonly known as CERN, have detected neutrinos created by the Large Hadron Collider (LHC) experiment for the very first time. These were the highest energy neutrinos that were ever produced in a laboratory setup and are similar to those found in particle showers from deep space.

First detected in 1956, neutrinos are subatomic particles that play a key role in the burning of stars. Every time nuclei of atoms either come together (fusion) or break apart (fission) in the universe, neutrinos are released.

Scientists unlock effect of psychedelic drug DMT on the human brain

Posted by in categories: biotech/medical, neuroscience

The powerful psychedelic can give you a near-death experience. Here is how it affects your brain on the inside.

Dimethyltryptamine, or DMT, is a powerful psychedelic whose effect on the human brain lasts for only some minutes, but in that short span of time, the user experiences some high-level mental changes.

The researchers examined the brain activity of the participants before, during, and after the DMT test. Here is what they found.

Research team finds indirect evidence for existence of dark matter surrounding black holes

Posted by in categories: computing, cosmology

Dark matter does not emit or reflect light, nor does it interact with electromagnetic forces, making it exceptionally difficult to detect. Nevertheless, a research team from The Education University of Hong Kong (EdUHK) has proven that there is a substantial amount of dark matter surrounding black holes. The study results are published in the journal The Astrophysical Journal Letters.

The team selected two nearby (A0620-00 and XTE J1118+480) as research subjects, with both considered as binary systems. That is, each of the black holes has a companion star orbiting it. Based on the orbits of the companion stars, observations indicate that their rates of orbital decay are approximately one millisecond (1ms) per year, which is about 50 times greater than the theoretical estimation of about 0.02ms annually.

To examine whether exists around black holes, the EdUHK team applied the “dark matter dynamical friction model”—a theory widely held in academia—to the two chosen binary systems, through computer simulations. The team found that the fast orbital decay of the companion stars precisely matches the data observed.
