Breast cancer: How chemotherapy may sometimes reactivate dormant cells

A study published in the journal PLOS Biology looked at the underlying pathways involved in breast cancer recurrence.

Researchers reported that a common chemotherapy treatment encouraged connective tissue cells to produce cytokines that helped reawaken dormant cancer cells.

The researchers say the results offer possible direction on adding other therapies to chemotherapy treatment to reduce the risk of breast cancer recurrence.

Researchers say a common chemotherapy may sometimes reactivate dormant breast cancer cells. They suggest supplemental therapies may be needed in these cases.

Google and the Department of Defense are building an AI-powered microscope to help doctors spot cancer

The Department of Defense has teamed up with Google to build an AI-powered microscope that can help doctors identify cancer.

The tool is called an Augmented Reality Microscope, and it will usually cost health systems between $90,000 to $100,000.

Experts believe the ARM will help support doctors in smaller labs as they battle with workforce shortages and mounting caseloads.

The pair ran the case through the special microscope, and Zafar was right. In seconds, the AI flagged the exact part of the tumor that Zafar believed was more aggressive. After the machine backed him up, Zafar said his colleague was convinced.

“He had a smile on his face, and he agreed with that,” Zafar told CNBC in an interview. “This is the beauty of this technology, it’s kind of an arbitrator of sorts.”

The AI-powered tool is called an Augmented Reality Microscope, or ARM, and Google and the Department of Defense have been quietly working on it for years. The technology is still in its early days and is not actively being used to help diagnose patients yet, but initial research is promising, and officials say it could prove to be a useful tool for pathologists without easy access to a second opinion.

New research offers insight about the reason mitochondria

New research provides insight about the bedrock scientific principle that mitochondrial DNA -; the distinct genetic code embedded in the organelle that serves as the powerplant of every cell in the body -; is exclusively passed down by the mother.

The study, a collaboration among Oregon Health & Science University and other institutions, published today in the journal Nature Genetics.

Scientists have long recognized the fact that mitochondrial DNA, or mtDNA, comes exclusively from egg cells in humans, meaning only the mother contributes the genetic code carried by thousands of mitochondria necessary for energy production in every cell in the body.

Strange Mathematical Pattern Found in The Cells of The Human Body

From the oxygen-carrying corpuscles in our blood to the branching neurons that govern our thoughts, our body is built of a dazzling variety of cells.

Researchers from institutions in Germany, Canada, Spain, and the US have published a comprehensive study of how many individual cells of each type there are in typical bodies.

Based on an exhaustive analysis of over 1,500 published sources, most adult males contain a total of around 36 trillion cells, while adult females tend to have some 28 trillion cells. A 10-year-old child, by comparison, would have in the region of 17 trillion.

In The Age Of AI, Everything Is An API

The API-AI nexus isn’t just for tech enthusiasts; its influence has widespread real-world implications. Consider the healthcare sector, where APIs can allow diagnostic AI algorithms to access patient medical records while adhering to privacy regulations. In the financial sector, advanced APIs can connect risk-assessment AIs to real-time market data. In education, APIs can provide the data backbone for AI algorithms designed to create personalized, adaptive learning paths.

However, this fusion of AI and APIs also raises critical questions about data privacy, ethical use and governance. As we continue to knit together more aspects of our digital world, these concerns will need to be addressed to foster a harmonious and responsible AI-API ecosystem.

We stand at the crossroads of a monumental technological paradigm shift. As AI continues to advance, APIs are evolving in parallel to unlock and amplify this potential. If you’re in the realm of digital products, the message is clear: The future is not just automated; it’s API-fied. Whether you’re a developer, a business leader or an end user, this new age promises unprecedented levels of interaction, personalization and efficiency—but it’s upon us to navigate it responsibly.

Light-Triggered Particles Deliver Photoimmunotherapy for Cancer

More noninvasive cancer treatments are being made:

A research group from Japan Advanced Institute of Science and Technology (JAIST) developed light-activatable, liquid metal (LM) nanoparticles for cancer diagnosis and treatment via photoimmunotherapy. The LM nanoparticles can target and destroy cancer cells and can be fluorescently tagged to function as reporters to identify and eliminate tumors in vivo.

Gallium (Ga)-based LM nanoparticles are promising nanoscale materials for biomedical applications due to their physicochemical properties, including flexibility, easy surface modification, efficient photothermal conversion, and high biocompatibility.
