A team of researchers at Stanford University has developed a novel hydrogel that contains four months' worth of medicine for a diabetic patient. This could make it easier for people to take their medicine, improve the quality of life for patients, and reduce complications associated with managing diabetes. The hydrogel is liquid enough to be easily injected with regular needles and solid enough to last for four months inside the body, and has shown promising results in both a rat animal model and a pig model.

This survey presents an end-to-end overview of quantum computing applications, their underlying algorithmic primitives, and their end-to-end complexities. It focuses on quantum circuit models and considers the dominant cost of quantum algorithms (nonClifford cost) in the context of quantum error correction and fault-tolerance schemes.

A research team, led by Professor Toru Miura from the University of Tokyo, shows how the expression of developmental genes in the Japanese green syllid worms, Megasyllis nipponica, helps form their swimming reproductive unit called stolon. Stolons develop their own eyes, antennae, and swimming bristles while still attached to their original body. The mystery surrounding the development of the stolon’s head within the original body has long perplexed scientists. The team found that head formation genes are highly expressed in the middle of the posterior end of the original body and Hox genes determine the body segmentation along the syllids’ body.

A research team has developed an autonomous 12-ton robot that can construct stone walls using advanced technologies. This robot could help the construction industry become more efficient, reduce waste, and lower its environmental impact. The robot is capable of efficiently excavating, sorting, and stacking the materials and can create digital inventories of materials to allow for easy repurposing and reuse. This robotic building process can save up to 41% in carbon dioxide emissions and could potentially serve as a proof of concept for the future of robotic construction.

University of Leicester computer scientists have developed novel technology to manage demands on mobile networks from multiple users using Terahertz frequencies. This could improve speed and power consumption for users of mobile devices, as well as help reap the benefits from the next generation of mobile technologies, 6G. The team tested their technology in simulations, finding that it outperformed existing technologies and can achieve a 10% power consumption reduction compared to other state-of-the-art technologies thanks to AI technologies, reinforcement learning in particular, being used to find the best parameters for the system. The study forms part of the 6G BRAINS project.

For the past week, a debate over the renewal of a controversial program of American surveillance (FISA Section 702) has been dominating my social feeds. The program, created in 2008, enables US agencies to collect electronic 'foreign intelligence information' without a warrant, potentially collecting data about Americans. Despite past abuses by intelligence agencies, critics from a broad coalition are pushing for reforms to the program. The main supporters are the intelligence agencies themselves, and the Biden administration has pushed for its reauthorization without reform. Ultimately, Congress must balance national security and individual rights.

In a small clinical trial of 10 people genetically prone to dangerously high levels of cholesterol, a single infusion of the precision gene editor reduced artery-clogging fat by up to 55%. This marks the first use of a newer class of gene editors directly in humans. VERVE-101 is a therapy designed to disable a gene encoding a liver protein that regulates cholesterol using base editing with nanoparticles. Although two people experienced severe heart issues, it is a breakthrough that base editing works efficiently in the liver.

Lelapa AI, a venture collaboration between two computer scientists, is trying to use machine learning to create tools that specifically work for Africans and put power back into the hands of African people. Recently, they've released Vulavula, an AI tool that can detect different languages spoken in South Africa. Although there are currently efforts being made to include certain languages in AI models, African AI researchers say these translations are still a long way from an accurate digital representation of African languages.

Cranberries are a 200-year-old domesticated berry found in U.S. households on Thanksgiving. They are hermaphroditic and rely on self-pollination, bumblebees, and honeybees for pollination, and have four air pockets which enable them to spread their seeds and be recovered from harvest.

This past weekend, OpenAI's board shocked people by firing CEO Sam Altman, leading to a coup and chaos. Mira Murati became the interim CEO, before Emmett Shear, the former CEO of Twitch, was appointed. Altman and Brockman accepted jobs at Microsoft, and 500 OpenAI employees have signed a letter to the board threaten to quit and join Altman. It's an example of the tension between trying to launch products quickly and slowing down development for safety. Shear appears to be a world away from Altman's pace of AI, promoting slowing down, carefulness, and ensuring safe technology. Despite all this, Sutskever believes OpenAI can continue to lead the field with the good ideas they have.

This year has been defined by unprecedented extreme weather events. Google DeepMind's AI, GraphCast, changes how we predict and prepare for these events. It achieved unprecedented accuracy by churning through more data faster. It also predicted the onset of extreme temperatures further into the future than current methods. This AI will help communities better prepare against extreme weather to potentially save lives.

A team of researchers from the University of Hong Kong have developed a novel kind of corrosion-resistant stainless steel that may be used for the manufacture of green hydrogen from saltwater. Its performance in a saltwater electrolyzer is equivalent to the present industrial practice of employing titanium as a key structural part. The new steel is estimated to reduce its structural material costs by approximately 40 times, which could be significnatly beneficial for hydrogen production from renewable sources.

Vegetables are rich sources of micronutrients like minerals, water-soluble vitamins and fat-soluble vitamins. Greens like collard greens, kale and spinach are rich sources of calcium, magnesium and iron, whereas orange vegetables like carrots, pumpkin, sweet potatoes, and squash are full of betacarotene, vitamin C, and potassium. White potatoes have high levels of vitamin B6 and vitamin K can be found in potatoes and green vegetables.

On November 14, 2023, Royal Australian naval personnel sustained minor injuries after being exposed to active sonar pulses from a nearby Chinese warship. Sonar is used for navigation, Anti-submarine warfare (ASW) and potentially disturbs marine life. It is not yet known if this incident was an accident or intentional, but the Australian government has contacted the Chinese government to develop a “clearer understanding” of the circumstances.

Agenting for regulation of AI technologies, the EU is aiming to capitalize on the use of AI without compromising it, while ensuring that no industries have an unfair competitive edge. French President Emmanuel Macron claims that regulation must be 'controlled, not punitive, to preserve innovation'. The French billionaires Xavier Niel, Rodolphe Saade, and Eric Schmidt have launched Kyutai, an AI research laboratory that has almost 300 million euros ($326 million) of investment, with Facebook's AI lab head Yann LeCun onboard.

When Covid-19 sent people home in early 2020, computer scientist Tom Zahavy rediscovered chess, and he eventually developed a research project to explore a way to weave together multiple decision-making AI systems that was more successful than the powerful AlphaZero AI chess program. This work showed off the capabilities of AI systems with more skill and creativity in solving problems, which could have bigger implications for complex problems well outside the game board.
