Submission + - New Drug Kills Cancer 20,000x More Effectively With No Detectable Side Effects (scitechdaily.com) 1

fahrbot-bot writes: SciTechDaily is reporting that researchers at Northwestern University have redesigned the molecular structure of a well-known chemotherapy drug, greatly increasing its solubility, effectiveness, and safety.

For this study, the scientists created the drug entirely from scratch as a spherical nucleic acid (SNA), a nanoscale structure that incorporates the drug into DNA strands surrounding tiny spheres. This innovative design transforms a compound that normally dissolves poorly and works weakly into a highly potent, precisely targeted treatment that spares healthy cells from damage.

When tested in a small animal model of acute myeloid leukemia (AML), an aggressive and hard-to-treat blood cancer, the SNA-based version showed remarkable results. It entered leukemia cells 12.5 times more efficiently, destroyed them up to 20,000 times more effectively, and slowed cancer progression by a factor of 59, all without causing noticeable side effects.

“In animal models, we demonstrated that we can stop tumors in their tracks,” said Northwestern’s Chad A. Mirkin, who led the study. “If this translates to human patients, it’s a really exciting advance. It would mean more effective chemotherapy, better response rates and fewer side effects. That’s always the goal with any sort of cancer treatment.”

Submission + - Here Come the Robot Swarms (wsj.com)

fjo3 writes: Forget teaching robots to think like humans. A field called swarm robotics is taking inspiration from ants, bees and even slime molds—simple creatures that achieve remarkable feats through collective intelligence.

Unlike traditional robots that take orders from a central computer, swarm robots work like ant colonies. No single robot is in charge, but the swarm accomplishes complex tasks through simple interactions between neighbors. Each robot interacts only with those nearby, sometimes communicating with sounds or chemical signals in particles they release.

Comment Scientific research is moving ahead very fast. (Score 1) 7

Scientific research is rapidly improving our lives and our understanding.

AI, "Artificial Intelligence", is rapidly advancing in the normal way. Many mistakes are found in the initial methods.

We have, in many areas of Physics, a limited understanding of the world around us. This research is one example of improvement.

Submission + - Mathematical proof debunks the idea that the universe is a computer simulation (phys.org)

alternative_right writes: Today's cutting-edge theory—quantum gravity—suggests that even space and time aren't fundamental. They emerge from something deeper: pure information.

This information exists in what physicists call a Platonic realm—a mathematical foundation more real than the physical universe we experience. It's from this realm that space and time themselves emerge.

"The fundamental laws of physics cannot be contained within space and time, because they generate them. It has long been hoped, however, that a truly fundamental theory of everything could eventually describe all physical phenomena through computations grounded in these laws. Yet we have demonstrated that this is not possible. A complete and consistent description of reality requires something deeper—a form of understanding known as non-algorithmic understanding."

Submission + - Japanese convenience stores are hiring robots run by workers in the Philippines

John.Banister writes: Teleoperated robot workers are here! No more worries about immigrants taking jobs, as the jobs themselves can be exported. Anything that isn't done by the cheapest labor can be exported to where the skilled labor is cheap. And, what better way to train AI replacements than the encoded stimulus and response of teleoperation?

Comment Eventually, less work for humans will be excellent (Score 1) 61

Quoting the story: "Human-only work is forecast to drop 27% over the next five years."

Robots will eventually be excellent for all of us. Most things we buy will cost less.

Maybe we will have 4-day or 3-day work weeks.

Humans will not be doing extremely boring jobs.
