Just like a gecko that regrows a broken tail, our peripheral nervous system knows how to regenerate the branches of its cells after an injury. Unfortunately, the cells in our central nervous system—our brain and spinal cord—are far more limited when it comes to regeneration.

Accordingly, diseases that lead to the degeneration and death of brain neurons, such as Alzheimer’s, Parkinson’s and ALS, are irreversible and incurable. So, what is it about the , which connects our brain and to the other organs, that gives it the power to regenerate itself so readily?

In a new study, researchers at the Weizmann Institute of Science have discovered that a protein, previously known to be expressed only during , plays a key role in regenerating adult neurons in the peripheral nervous system.

Researchers from the University of Oxford have achieved a major advancement toward realizing miniature bio-integrated devices, capable of directly stimulating cells. Their findings were recently published in the journal Nature.

Small bio-integrated devices that can interact with and stimulate cells could have important therapeutic applications, such as targeted drug delivery and promoting faster wound recovery. A major obstacle, however, has been providing an efficient microscale power source for these devices, a challenge that has remained unsolved.

To address this, researchers from the University of Oxford.

Zirconium, the metal extracted from the mineral, zircon, may not be well-known, but its remarkable properties make it indispensable in nuclear power, the chemical industry, medicine and more. Since ancient times, zircon — a word believed to have originated from the Persian zargun, meaning gold-like — has been used in jewellery and decorations.

The IAEA has released The Metallurgy of Zirconium, a three-volume publication offering a comprehensive overview of the metal, its extraction, properties and applications in nuclear energy. Here are five interesting facts about zirconium.

A collaboration between researchers at the University of Sheffield and Budapest Zoo sees an aging gorilla walk again with ease. Will this treatment be fruitful for humans?

Scientists at the university of sheffield.

Liesel, the elderly matriarch of the Budapest Zoo, had been struggling to walk on her left leg, signaling a possible battle with arthritis. This marked the initiation of a unique collaboration between veterinary expertise and cutting-edge science to alleviate the suffering of the aging primate.

The research paper reviews the potential benefits of marine plasmalogens, a type of glycerophospholipid, in combating age-related diseases like Alzheimer’s and Parkinson’s. These compounds, abundant in marine resources, could improve lipid metabolism and reduce oxidative stress, offering a new avenue for improving the quality of life in aging populations.

The complexity and rise of data in healthcare means that artificial intelligence (AI) will increasingly be applied within the field. Several types of AI are already being employed by payers and providers of care, and life sciences companies. The key categories of applications involve diagnosis and treatment recommendations, patient engagement and adherence, and administrative activities. Although there are many instances in which AI can perform healthcare tasks as well or better than humans, implementation factors will prevent large-scale automation of healthcare professional jobs for a considerable period. Ethical issues in the application of AI to healthcare are also discussed.

KEYWORDS: Artificial intelligence, clinical decision support, electronic health record systems.

Artificial intelligence (AI) and related technologies are increasingly prevalent in business and society, and are beginning to be applied to healthcare. These technologies have the potential to transform many aspects of patient care, as well as administrative processes within provider, payer and pharmaceutical organisations.

“It’s a time of huge uncertainty,” says Geoffrey Hinton from the living room of his home in London. “Nobody really knows what’s going to happen … I’m just sounding the alarm.”

In The Godfather in Conversation, the cognitive psychologist and computer scientist ‘known as the Godfather of AI’ explains why, after a lifetime spent developing a type of artificial intelligence known as deep learning, he is suddenly warning about existential threats to humanity.

A University of Toronto University Professor Emeritus, Hinton explains how neural nets work, the role he and others played in developing them and why the kind of digital intelligence that powers ChatGPT and Google’s PaLM may hold an unexpected advantage over our own. And he lays out his concerns about how the world could lose control of a technology that, paradoxically, also promises to unleash huge benefits – from treating diseases to combatting climate change.
