Hologram Breakthrough — New Technology Transforms Ordinary 2D Images

Posted by in categories: biotech/medical, computing, holograms, virtual reality

Holograms provide a three-dimensional (3D) view of objects, offering a level of detail that two-dimensional (2D) images cannot match. Their realistic and immersive display of 3D objects makes holograms incredibly valuable across various sectors, including medical imaging, manufacturing, and virtual reality.

Traditional holography involves recording an object’s three-dimensional data and its interactions with light, a process that demands high computational power and the use of specialized cameras for capturing 3D images. This complexity has restricted the widespread adoption of holograms.

Quantum Computing for Complete Beginners

Posted by in categories: computing, particle physics, quantum physics

Some have described the last several millennia of human dominion over the earth’s resources as the anthropocene, deriving from the Greek “anthropo” meaning human, and “cene” meaning recent. The last century in particular has been dubbed the fourth industrial revolution, due to the pace of technological innovation ushered in by the advent of computers in the middle of the 20th century.

In the past seventy years, computation has transformed every aspect of society, enabling efficient production at an accelerated rate, displacing human labour from chiefly production to services, and exponentially augmenting information storage, generation, and transmission through telecommunications.

How did we get here? Fundamentally, technological advancement draws on existing science. Without an understanding of the nature of electromagnetism and the structure of atoms, we wouldn’t have electricity and the integrated circuitry that power computers. It was only a matter of time, then, before we thought of exploiting the most accurate, fundamental description of physical reality provided by quantum mechanics for computation.

Pelvic Radiotherapy Induces Long-Term Inflammation in Cancer Survivors

Posted by in categories: biotech/medical, health

Radiotherapy (also called radiation therapy), a commonly used cancer treatment that uses high-energy radiation, can effectively eliminate or shrink various types of tumors. While radiotherapy benefits many cancer patients, the associated side effects can hinder cancer survivors’ quality of life and overall health.

When a patient receives radiation treatments, the radiation damages the DNA. If the DNA damage becomes severe enough, the cancer cell will not recover and will stop dividing and die. Unfortunately, the exact mechanisms by which radiation elicits cancer cell death can cause similar damage in nearby healthy cells, leading to significant toxicities in some cases.

Many malignancies that develop in the pelvic region, including urinary and rectal cancers, are susceptible to pelvic radiotherapy. Some patients receiving pelvic radiotherapy develop debilitating bowel symptoms, including intestinal inflammation. Doctors do not fully understand these clinical challenges despite the common occurrence of bowel symptoms following pelvic radiotherapy. A better understanding of the link between radiation and bowel damage could help doctors manage cancer treatment more optimally, enhancing survivorship.

Scientists Just Came Up With a Wild Idea For Making Oxygen on Mars

Posted by in categories: habitats, space travel, sustainability

Desert-dwelling bacteria that feed on sunlight, slurp up carbon dioxide, and emit oxygen could be incorporated into paint that supplements the air in a habitat on Mars.

It’s called Chroococcidiopsis cubana, and scientists have developed a biocoating that emits measurable amounts of oxygen on a daily basis while reducing the amount of carbon dioxide in the air around it. This has implications, not just for space travel but here at home on Earth, too, according to a team led by microbiologist Simone Krings of the University of Surrey in the UK.

“With the increase in greenhouse gasses, particularly CO2, in the atmosphere and concerns about water shortages due to rising global temperatures, we need innovative, environmentally friendly, and sustainable materials,” says bacteriologist Suzie Hingley-Wilson of the University of Surrey.

Google Researchers Unveil Unique Form of Quantum Teleportation

Posted by in category: quantum physics

Quantum mechanics is full of weird phenomena, but perhaps none as weird as the role measurement plays in the theory. Since a measurement tends to destroy the “quantumness” of a system, it seems to be the mysterious link between the quantum and classical world.

Furthermore, when dealing with a vast system of quantum data units called “qubits,” the impact of measurements can lead to profoundly different outcomes, even driving the emergence of entirely new phases of quantum information.

This happens when two competing effects come to a head: interactions and measurement. In a quantum system, when the qubits interact with one another, their information becomes shared nonlocally in an “entangled state.”

Health crisis: 220,000 planes still use lead fuel, warns US agency

Posted by in categories: energy, government, health, transportation

Congress is currently debating the FAA’s long-term reauthorization, which might have an impact on the ongoing use of leaded aviation fuel at smaller airports.

Researchers unveil ‘3D-GPT’, an AI that can generate 3D worlds from simple text commands

Posted by in category: robotics/AI

VentureBeat presents: AI Unleashed — An exclusive executive event for enterprise data leaders. Network and learn with industry peers. Learn More

Researchers from the Australian National University, the University of Oxford, and the Beijing Academy of Artificial Intelligence have developed a new AI system called “3D-GPT” that can generate 3D models simply from text-based descriptions provided by a user.

The system, described in a paper published on arXiv, offers a more efficient and intuitive way to create 3D assets compared to traditional 3D modeling workflows.

Amazon Field-Testing Awe-Inspiring Digit Bipedal Robot

Posted by in categories: employment, robotics/AI, sustainability, transportation

Amazon is always on the frontier of technological advancements, and in a recent move, the e-commerce giant announced its plans to deepen its collaboration with Agility Robotics. As part of their ongoing partnership, Amazon will commence tests using the bipedal robot, Digit, in its operations. This exciting development comes after Amazon’s strategic investment in Agility Robotics through the Amazon Industrial Innovation Fund.

For those unfamiliar with Digit, it’s a marvel of modern robotic engineering. Developed by Agility Robotics, Digit stands out with its unique bipedal design. It isn’t just any robot; it’s designed with two legs, allowing it to move and operate in human-like ways, making it exceptionally fit for environments crafted for humans. Equipped with advanced sensors like LIDAR, it perceives its surroundings and avoids obstacles with ease. Its arms are adept at maintaining balance, carrying objects, and interacting with various elements of its environment.

NVIDIA’s latest AI model helps robots perform pen spinning tricks as well as humans

Posted by in categories: biotech/medical, information science, robotics/AI

Eureka has also taught quadruped, dexterous hands, cobot arms and other robots to open drawers, use scissors, catch balls and nearly 30 different tasks. According to NVIDIA Research, the AI agent’s trial and error-based reward programs are 80 percent more effective than those written by human experts. This shift meant the robots’ performance also improved by over 50 percent. Eureka also self-evaluates based on training results, instructing changes in reward functions as it sees fit.

NVIDIA Research has published a library of its Eureka algorithms, encouraging others to try them out on NVIDIA Isaac Gym, the organization’s “physics simulation reference application for reinforcement learning research.”

The idea of robots teaching robots is seeing increased interest and success. A May 2023 paper published in the Transactions on Machine Learning Research journal presented a new system called SKILL (Shared Knowledge Lifelong Learning), which allowed AI systems to learn 102 different skills, including diagnosing diseases from chest X-rays and identifying species of flowers. The AIs shared their knowledge — acting as teachers in a way — with each other over a communication network and were able to master each of the 102 skills. Researchers at schools like MIT and the University of Bristol have also had success, specifically in using AI to teach robots how to manipulate objects.
