This is pretty impressive, they can move around individual cells. Video in comments:
Researchers at the HUN-REN Biological Research Centre, Szeged, have developed tiny tools to capture individual cells. According to their study published in the journal Advanced Materials, key innovations of using flexible microrobots is that they do not require any treatment of the cells to grab them and also allow the cells to be released after examination, enabling more efficient investigations than ever before.

A digital “primordial soup” with no rules or direction can lead to the emergence of self-replicating artificial life forms, in an experiment that may hint at how biological life began on Earth.
I have recently read the report from Sharad Agarwal, and here are my outcomes by adding some examples:
Transhumanism is the concept of transcending humanity’s fundamental limitations through advances in science and technology. This intellectual movement advocates for enhancing human physical, cognitive, and ethical capabilities, foreseeing a future where technological advancements will profoundly modify and improve human biology.
Consider transhumanism to be a kind of upgrade to your smartphone. Transhumanism, like updating our phones with the latest software to improve their capabilities and fix problems, seeks to use technological breakthroughs to increase human capacities. This could include strengthening our physical capacities to make us stronger or more resilient, improving our cognitive capabilities to improve memory or intelligence, or even fine-tuning moral judgments. Transhumanism, like phone upgrades, aspires to maximize efficiency and effectiveness by elevating the human condition beyond its inherent bounds.
A long-term study since 1929 has revealed significant insights into barley’s evolution, showing its adaptation to different environments and the substantial impact of natural selection. This research underscores the limitations of evolutionary breeding and highlights the need for further exploration to enhance crop yields.
Utilizing one of the world’s oldest biological experiments, which commenced in 1929, researchers have revealed how barley, a major crop, has been influenced by agricultural pressures and its evolving natural environment. These findings highlight the significance of long-term studies in comprehending the dynamics of adaptive evolution.
The survival of cultivated plants after their dispersal across different environments is a classic example of rapid adaptive evolution. For example, barley, an important neolithic crop, spread widely after domestication over 10,000 years ago to become a staple source of nutrition for humans and livestock throughout Europe, Asia, and Northern Africa over just a few thousand generations. Such rapid expansion and cultivation have subjected the plant to strong selective pressures, including artificial selection for desired traits and natural selection by being forced to adapt to diverse new environments.
“Mind uploading speculation and debate often concludes that a procedure described as gradual in-place replacement preserves personal identity while a procedure described as destructive scan-and-copy produces some other identity in the target substrate such that personal identity is lost along with the biological brain. This paper demonstrates a chain of reasoning that establishes metaphysical equivalence between these two methods in terms of preserving personal identity.” — Keith Wiley https://keithwiley.com https://www.brainpreservation.org/tea… thanks for tuning in!

Spider spidroin revives the silken splendor.
In their quest to make silk powerful again, not by status but rather by thread strength, scientists turned to an arachnoid. Dragline silk, the thread by which the spider hangs itself from the web, is one of the strongest fibers; its tensile strength—a measure of how much a polymer deforms when strained—is almost thrice that of silkworm silk.2
Beyond durable fashion garments, tough silk fibers are coveted in parachutes, military protective gear, and automobile safety belts, among other applications, so scientists are keen to pull on these threads. While traditional silk production relies on sericulture, arachnophobes can relax: spider farms are not a thing.
