While mitochondria play a crucial role in producing the energy our cells need to carry out their various functions, when damaged, they can have profound effects on cellular function and contribute to the development of various diseases.

Broken-down mitochondria are usually removed and recycled through a garbage disposal process known as “mitophagy.”

PINK1 and Parkin are two proteins vital to this process, responsible for “tagging” malfunctioning mitochondria for destruction. In Parkinson’s disease, mutations in these proteins can result in the accumulation of damaged mitochondria in the brain, which can lead to motor symptoms such as tremors, stiffness and difficulty with movement.

While autonomous robots have started to move out of the lab and into the real world, they remain fragile. Slight changes in the environment or lighting conditions can easily throw off the AI that controls them, and these models have to be extensively trained on specific hardware configurations before they can carry out useful tasks.

This lies in stark contrast to the latest LLMs, which have proven adept at generalizing their skills to a broad range of tasks, often in unfamiliar contexts. That’s prompted growing interest in seeing whether the underlying technology—an architecture known as a transformer—could lead to breakthroughs in robotics.

In new results, researchers at DeepMind showed that a transformer-based AI called RoboCat can not only learn a wide range of skills, it can also readily switch between different robotic bodies and pick up new skills much faster than normal. Perhaps most significantly, it’s able to accelerate its learning by generating its own training data.

When an animal takes notice of an approaching figure, it needs to determine what it is, and quickly. In nature, competition and survival dictate that it’s better to think fast—that is, for the brain to prioritize processing speed over accuracy. A new study shows that this survival principle may already be wired in the way the brain processes sensory information.

Kumar and fellow KTH neuroscientist Pawel Herman collaborated with KTH information theorists Movitz Lenninger and Mikael Skoglund to study input processing in the brain using information theory and computer models of the brain. Neuroscientist Arvind Kumar, an associate professor at KTH Royal Institute of Technology, says that the study offers a new view of neural coding of different types of inputs in the brain.

The new study surprisingly shows that initial visual processing is “quick but sloppy” in comparison to information processing in other parts of the brain’s vast neural network, where accuracy is prioritized over speed. The paper is published in the journal eLife.

Artificial intelligence (AI) is transforming the world as we know it, and product management is no exception. It has the potential to revolutionize customer research, decision-making and much more, providing us with data-driven insights and paving the way for a future that is not only intelligent but intuitive.

With AI at our fingertips, we’re standing at the threshold of a new era in product management. However, integrating AI into product management also presents challenges that must be addressed. We will delve into how AI influences the world of product management and what it holds for the future.

Scientists at the University of Cambridge have used powerful new brain imaging techniques to reveal a neurochemical imbalance within regions of the frontal lobes in patients with obsessive-compulsive disorder (OCD). The research findings are published in the journal Nature Communications.

The study shows that the balance between glutamate and GABA—two major neurotransmitter chemicals—is “disrupted” in OCD patients in two frontal regions of the brain.

Researchers also found that people who do not have OCD but are prone to habitual and compulsive behavior have increased glutamate levels in one of these brain regions.

Prof. Yossi Buganim and his research team at the Faculty of Medicine at the Hebrew University of Jerusalem have achieved a groundbreaking milestone in the field of cell reprogramming. Their latest study, published in Nature Communications, reveals a remarkable breakthrough in converting skin samples into functional human placenta cells. This achievement has significant implications for understanding pregnancy development, studying pregnancy-related diseases, and advancing cell therapies.

The research opens new avenues for investigating the causes of infertility, complications during pregnancy, and long-term health implications for both mothers and babies.

Reprogramming cells to assume new identities has been a focus of Prof. Buganim’s lab, which utilizes specialized proteins to modify gene expression. By transforming skin cells into other cell types, the team enables the study of specific diseases and the potential development of cell-based therapies. However, accessing cells from the placenta, a critical organ in pregnancy, has long been a challenge due to technical and ethical constraints.

Australian startup Synchron, backed by Bill Gates and Jeff Bezos, looks set to beat Elon Musk’s Neuralink to market with a safe, reliable brain-computer interface that any hospital can quickly install – without cutting a hole in your skull.

Volvo Cars is another automaker that officially announced a switch from the Combined Charging System (CCS1) to Tesla’s North American Charging Standard (NACS) charging connector in North America (United States, Canada, and Mexico).

Volvo entered into an agreement with Tesla to use the NACS charging connector, as the first European brand. Previously, a similar move was announced by Ford, General Motors, and Rivian, not forgetting about Aptera (an EV start-up).

According to Volvo, the deal with Tesla will open the Tesla Supercharging network (more than 12,000 stalls in more than 2,000 locations) for all existing Volvo BEVs from the first half of 2024. However, the CCS1-compatible Volvo cars (XC40, C40 Recharge, and the upcoming XC30 and XC90) will have to use a NACS to CCS1 adapter.

Andreessen argues that thanks to A.I., “productivity growth throughout the economy will accelerate dramatically, driving economic growth, creation of new industries, creation of new jobs, and wage growth, and resulting in a new era of heightened material prosperity across the planet.”

This week, on the Lex Fridman Podcast, he offered advice to young people who want to stand out in what he describes in this “freeze-frame moment” with A.I.—where tools like ChatGPT and GPT-4 are suddenly available and “everybody is kind of staring at them wondering what to do.”
