Zambia site shows humans made wood structures 500k years ago

Posted by in categories: evolution, materials

Professor Geoff Duller from Aberystwyth University explained that, given the considerable age of these artifacts, assigning precise dates to them presented a significant challenge. To address this issue, luminescence dating techniques were employed. These innovative dating methods have broad-ranging implications, enabling the dating of much older materials and facilitating the reconstruction of sites that offer insights into human evolution—in the case of Kalambo Falls, an excavation conducted in the 1960s yielded comparable wooden fragments. Still, their dating had remained elusive, leaving the true importance of the site uncertain until now.

Kalambo Falls is located on the Kalambo River above a 772-foot (235-meter) waterfall on the border of Zambia and Tanzania near Lake Tanganyika. The area is on a ‘tentative ‘list from UNESCO for becoming a World Heritage site because of its archaeological significance.

Elon Says Future Starships Will be 20% Longer

Posted by in categories: Elon Musk, space travel

The SpaceX Super Heavy Starship is already the largest and most powerful rocket ever built. Elon tweeted that future versions will be 10% to 20% longer. If the 20% longer development happens then the stacked rocket will be 144 meters long. Adding 24 meters would be over 60% of the length of the Space Shuttle orbiter which was 37 meters long.

Likely to be 10% to 20% longer in later versions.

How can quantum computers be better than classical computers?

Posted by in categories: quantum physics, robotics/AI

Scientists have been exploring both experimental and theoretical ways to prove quantum supremacy.

Ramis Movassagh, a researcher at Google Quantum AI, recently had a study published in the journal Nature Physics. Here, he has reportedly demonstrated in theory that simulating random quantum circuits and determining their output will be extremely difficult for classical computers. In other words, if a quantum computer solves this problem, it can achieve quantum supremacy.

Israeli Researchers Develop Method for Safely Detecting Landmines — Using Bacteria

Posted by in categories: chemistry, innovation

By John Jeffay, ISRAEL21c

Researchers in Israel have announced a breakthrough in safely detecting landmines – using bacteria.

They’ve developed tiny pellet-sized biosensors based on E. coli. The biosensors are dispersed over the target area, where they sniff out the chemical signature of buried explosives and become luminescent.

Rewiring tumor mitochondria enhances the immune system’s ability to recognize and fight cancer

Posted by in category: biotech/medical

Immunotherapy, which uses the body’s own immune system to fight cancer, is an effective treatment option, yet many patients do not respond to it. Thus, cancer researchers are seeking new ways to optimize immunotherapy so that it is more effective for more people.

Now, Salk Institute scientists have found that manipulating an early step in in mitochondria—the cell’s powerhouses—reduces melanoma growth and enhances the in mice.

The study, published in Science on September 21, 2023, revealed that when electrons take one of two initial routes through mitochondria, genes and proteins become activated that are needed for to recognize and kill .

“Sampling led to hip-hop… AI music has the potential to do something similar”, says Holly Herndon

Posted by in categories: media & arts, robotics/AI

I have said it time and time again. Ironically I have been an electronic music producer for decades.

Electronic producer, singer and AI advocate Holly Herndon has drawn a comparison between AI music and sampling, saying that AI music could impact music in the same way sampling did hip-hop.

Herndon made the statement during a recent interview with Mixmag, as part of a feature entitled The rise of AI music: a force for good or a new low for artistic creativity? The feature explores the advantages and disadvantages of using AI technology to create music.

MRI-Compatible Stereotactic Neurosurgery Robot

Posted by in categories: biotech/medical, government, robotics/AI

What does it take to bring life-changing medical robotic devices to reality? This is a question Dr. Gregory Fischer, founder and CEO of AiM Medical Robotics, explored in his keynote “From Concept to Commercialization: It’s not Brain Surgery, or is it?” at BIOMEDevice Boston, MA. As a researcher, professor, and lead investigator supported by federal government grants, director of a state-funded medtech accelerator, and founder of multiple medical device companies, Fischer has a unique perspective on conceptualizing, refining, and commercializing medical devices, as well as the challenges that come with each step.

Focusing on neurosurgery, he highlighted specific challenges clinicians face during procedures including an inability to leverage real-time intraoperative MR imaging for precision — surgeons must transfer a patient mid-surgery to an MRI in a separate room and sometimes even a separate building within the hospital complex — resulting in inefficient workflow and interruptions in sterility and anesthesia during transfers. Additionally, he mentioned limited compatibility with various MRI scanners, and an increased risk of human errors because of complex manual processes.

Integrating robotic assistance, he said, enhances the reachable target area and improves dexterity and precision of motion during such difficult procedures such as neurosurgery, adds enhanced feedback and virtual fixtures, reduces procedure time, and avoids ergonomic issues. An increase in intervention accuracy through inherent integration with image guidance tools, and improved diagnostic and therapeutic outcomes are also advantages of robotic assistance, according to Fischer.
