What's strange to me is that the human tissue didn't just survive inside the mice, but was able to grow and integrate with the mouse's nervous system too.

The ability of human cells to grow in this way is quite impressive.

I'm wondering what people's opinions are on the ethics of this kind of research, especially if the development progresses further.

It's interesting to see how housing inventory has returned to near-2015 levels, yet affordability and financing conditions are so different today. Same supply, very different market.

A very interesting perspective on the interaction between aliens and us, even though I do not agree with every idea stated in this article. Some of the points made in the article about how aliens might view us are very interesting.

After seeing people waiting in line at the Post Office with their Amazon boxes filled with returns, I wondered about the additional costs incurred. One 2026 study shows that, of the nearly 10,000 shoppers across ten countries, around 15% of frequent returners generate about 60% of the total CO₂ emissions associated with online returns. I was really surprised to learn this and to realise how much it really costs us.

The key point is that the asking prices have become disconnected from what’s actually reasonable. Many sellers, including landlords and investors, are clinging to high prices reminiscent of a few years back. Meanwhile, buyers are faced with rising interest rates and escalating service fees, the numbers no longer add up. Factor in short lease terms and maintenance responsibilities, and it becomes clear that numerous flats aren’t just overpriced, they're also unsupported by banks for lending. With almost 90% of property listings in London remaining stagnant for over six months, potential buyers are setting firm limits until sellers adjust their expectations accordingly.

An extensive new study of 300 million medical tests that involve more than 1 million women shows that menopause may bring about more sudden changes in the female body than expected. Researchers who correlated the data with the time when women had their last period found sudden changes in their bodies: hormones, bones, liver, iron and kidney levels. For instance, ferritin (iron stores) seems unchanging throughout life, but it shows a sudden rise at menopause. In addition, the researchers learned that hormonal changes begin at least ten years before menopause, which accounts for many feelings of perimenopause experienced. Though the article is only a preprint (has not yet undergone proper peer-reviewing procedure), it contains interesting content.

Home builders are reducing costs and adding benefits, but sellers of existing homes remain firm in their pricing. With new homes now costing less than existing homes, how long can this price margin continue?
