Researchers should avoid the lure of proprietary models and develop transparent large language models to ensure reproducibility.
Alphabet Inc is combining Google Brain and DeepMind, as it doubles down on artificial intelligence research in its race to compete with rival systems like OpenAI’s ChatGPT chatbot.
The new division will be led by DeepMind CEO Demis Hassabis and its setting up will ensure “bold and responsible development of general AI,” Alphabet CEO Sundar Pichai said in a blog post on Thursday (20 April).
Alphabet said the teams that are being combined have delivered a number of high-profile projects including the transformer, technology that formed the bedrock of some of OpenAI’s own work.
A giant orbital magnetic moment exists in graphene quantum dots, according to new work by physicists at the University of California Santa Cruz in the US. As well as being of fundamental interest for studying systems with relativistic electrons – that is those travelling at near-light speeds – the work could be important for quantum information science since these moments could encode information.
Graphene, a sheet of carbon just one atom thick, has a number of unique electronic properties, many of which arise from the fact that it is a semiconductor with a zero-energy gap between its valence and conduction bands. Near where the two bands meet, the relationship between the energy and momentum of charge carriers (electrons and holes) in the material is described by the Dirac equation and resembles that of a photon, which is massless.
These bands, called Dirac cones, enable the charge carriers to travel through graphene at extremely high, “ultra-relativistic” speeds approaching that of light. This extremely high mobility means that graphene-based electronic devices such as transistors could be faster than any that exist today.
Scientists have confirmed that intrinsic alignments of galaxies can probe dark matter and dark energy on a cosmological scale, supporting general relativity at vast spatial scales. However, the nature of dark energy and cosmic acceleration remains unresolved.
Einstein would nod in approval. General relativity may apply even in the farthest reaches of the universe.
Now, scientists from international research institutions, including Kyoto University, have confirmed that the intrinsic alignments of galaxies have characteristics that allow it to be a powerful probe of dark matter and dark energy on a cosmological scale.
Black holes have always been fascinating to scientists and the general public alike. They are so mysterious that even light can’t escape.
Researchers repurpose tiny bacterial injection systems to specifically inject a wide variety of proteins into human cells and living mice.
The first 2 minutes includes the best layman description of how ChapGPT works that I’ve heard yet:
Ready to blast off into a new world of gaming? In this exciting video, we’re taking AI to the next level as we install ChatGPT as a co-pilot in my SimPit game station. But this isn’t just your average AI installation — get ready for a hilarious space adventure as we explore the ups and downs of integrating ChatGPT into our gaming setup.
But before we launch into the fun, we’ll start by demystifying web APIs and explaining what AI is all about. Then, it’s time to dive into the installation process and see just how “easy” it is to set up ChatGPT as your very own AI co-pilot. You’ll learn all about the web APIs used to connect ChatGPT to your SimPit and get a firsthand look at the benefits of having an AI co-pilot by your side during gameplay.
Jeremy Hunt tells POLITICO the West needs to be ‘super smart’ about artificial intelligence rules, but pushes back at doom-laden warnings.
Metabolic (bariatric) surgery is more effective than medications and lifestyle interventions for the treatment of advanced non-alcoholic fatty liver disease.
A new paper, published today in The Lancet by King’s College London and the Catholic University of Rome, is the first to compare three active treatments of non-alcoholic steatohepatitis (NASH) and to specifically investigate the effectiveness of metabolic surgery (weight loss surgery) in a randomized clinical trial.
Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease, globally affecting 55% of people with type 2 diabetes and 75% of those with obesity. Non-alcoholic steatohepatitis (NASH) is the progressive form of the disease, and is characterized by liver cell injury and inflammation, which induce liver fibrosis (scarring of the tissue). Left untreated, it can lead to liver failure and liver cancer, and is one of the leading causes of liver transplant in the western world.
A stroke occurs when an artery in the brain becomes blocked or bursts. The brain cells beyond the blockage or bleed are deprived of oxygen and nutrients, so are damaged or die.
Scientists have been trying to find ways to minimize the damage following a stroke and speed up recovery.
Now, a study led by scientists from Weill Cornell Medicine has found changes in gene activity in small blood vessels following a stroke. The findings suggest that these changes could be targeted with existing or future drugs to mitigate brain injury or improve stroke recovery.
