First Evidence that Black Holes are the Source of Dark Energy

Posted by in categories: cosmology, physics

😗


Observations of supermassive black holes at the centers of galaxies point to a likely source of dark energy – the ‘missing’ 70% of the Universe.

A Biodegradable Computer Chip That Performs Surprisingly Well

Posted by in categories: computing, sustainability

Year 2015 face_with_colon_three


Biodegradable, wood-based computer chips can perform just as well as chips commonly used for wireless communication, according to new research.

The inventors argue that the new chips could help address the global problem of rapidly accumulating electronic waste, some of which contains potentially toxic materials. The results also show that a transparent, wood-derived material called nanocellulose paper is an attractive alternative to plastic as a surface for flexible electronics.

‘Metasurfaces’ could spark next generation of significantly thinner and cheaper flat screens

Posted by in categories: energy, nanotechnology

Researchers have developed a proof of concept technology that could pave the way for next-generation displays beyond current LCDs and LEDs, enabling screens and electronic devices to become thinner, offer higher resolution and be much more energy efficient.

A team at Nottingham Trent University, the Australian National University and the University of New South Wales Canberra in Australia has engineered electrically tunable arrays of nanoparticles called “metasurfaces,” which can offer significant benefits over current liquid crystal displays.

Today’s display market offers a large range of choices, each with its pros and cons. However factors including production costs, lifespan and energy consumption have kept liquid crystal technology the most dominant and popular technology for screens such as TV sets and monitors.

5th person confirmed to be cured of HIV

Posted by in category: biotech/medical

Researchers are announcing that a 53-year-old man in Germany has been cured of HIV.

Referred to as “the Dusseldorf patient” to protect his privacy, researchers said he is the fifth confirmed case of an HIV cure. Although the details of his successful treatment were first announced at a conference in 2019, researchers could not confirm he had been officially cured at that time.

Today, researchers announced the Dusseldorf patient still has no detectable virus in his body, even after stopping his HIV medication four years ago.

Top Large Language Models (LLMs) in 2023 from OpenAI, Google AI, Deepmind, Anthropic, Baidu, Huawei, Meta AI, AI21 Labs, LG AI Research and NVIDIA

Posted by in category: robotics/AI

Large language models are computer programs that can analyze and create text. They are trained using massive amounts of text data, which helps them become better at tasks like generating text. Language models are the foundation for many natural language processing (NLP) activities, like speech-to-text and sentiment analysis. These models can look at a text and predict the next word. Examples of LLMs include ChatGPT, LaMDA, PaLM, etc.

Parameters in LLMs help the model to understand relationships in the text, which helps them to predict the likelihood of word sequences. As the number of parameters increases, the ability of the model to capture complex relationships and its flexibility in handling rare words also increases.

ChatGPT is an open-source chatbot powered by the GPT-3 language model. It is capable of engaging in natural language conversations with users. ChatGPT is trained on a wide array of topics and can assist with various tasks like answering questions, providing information, and generating creative content.

Caught in the act: supermassive black hole 8.5 billion light years away has violent stellar snack

Posted by in categories: cosmology, materials

A supermassive black hole at the centre of a galaxy some 8.5 billion years way has ripped apart a nearby star, producing some of the most luminous jets ever seen.

When stars and other objects stray too close to a supermassive black hole they are destroyed by the black hole’s immense gravity.

These occurrences, known as tidal-disruption events (TDEs), result in a circling disk of material that is slowly pulled into the black hole and very occasionally, as in the case of supermassive black hole AT2022cmc, ejecting bright beams of material travelling close to the speed of light.

Researchers provide a framework for unifying and categorizing neurodegenerative diseases based on eight hallmarks

Posted by in categories: biotech/medical, genetics, neuroscience

In a recent study published in Cell, researchers presented eight hallmarks of neurodegenerative diseases (NDDs), their in vivo biomarkers, and interactions to help categorize NDDs and specify patients within a specific NDD.

Despite being linked to rare genetic forms, all eight NDD hallmarks (cellular/molecular processes) also contribute to sporadic NDDs. In addition, they contribute to neuronal loss in preclinical (animal) models and NDD patients, manifesting as an altered molecular (hallmark) biomarker.

An NDD patient could have defects in multiple NDD hallmarks. However, the primary NDD hallmark depends on the NDD insult and the neuronal susceptibility and resilience, i.e., one’s ability to handle insults in the affected brain region.
