These include rugged small vehicles with tracks, cameras and sensors that can search inside rubble and climb over obstacles. Teledyne FLIR, a sensing technology specialist based in Oregon in the United States, used robots like these in June 2021 when a tower block partially collapsed in the Miami suburb of Surfside in Florida.

In Japan, university teams are developing another type of search and rescue robot – a hose-like robot with a video camera called the Active Scope Camera that can search inside collapsed buildings. Drones also help search and rescue teams see disaster sites from above.

Upcycling a vintage milling machine for CNC control while adding a fourth axis isn’t for the fainthearted, but the results are impressive.

ChatGPT-style AI tools that are limited to enterprise information are being considered. Here’s what that technology could mean for you and your organization.

Implanted brain electrodes send signals that bypass damaged spinal cord area, using man’s thoughts to stimulate leg movement.

So it is confirmed that the new variant of covid 19 virus is here but the actual spike now is in China. But will most likely spread globally much how previous viruses have done. Be sure to be prepared for another pandemic. Anyway what may be the possible cure would be new bioengineering techniques with crispr to eventually be immune to the virus like I have posted in some genetically engineered cells recently were made. But rest assured this could lead to a global pandemic because the current variant is taxing our current vaccination measures.

The country once had some of the harshest Covid restrictions on the planet, but the response from the government and the public is relatively muted this time.

Scientists in Finland have developed a nanodevice that can measure the absolute power of microwave radiation down to the femtowatt level at ultra-low temperatures—a scale trillion times lower than routinely used in verifiable power measurements. The device has the potential to significantly advance microwave measurements in quantum technology.

Quantum science takes place mostly at ultra-low temperatures using devices called dilution refrigerators. The experiments also have to be done at tiny energy levels—down to the energy level of single photons or even less. Researchers have to measure these extremely low energy levels as accurately as possible, which means also accounting for heat—a persistent problem for quantum devices.

If there are energy fluctuations in a quantum vacuum, very interesting things can happen. For example, the E = mc² relation tells us that energy and matter are interconvertible. A vacuum energy fluctuation can be converted into particles of matter. Sounds weird? Maybe, but it happens all the time. These particles are called virtual particles, living a fleeting existence before plunging back into the ever-busy quantum vacuum.

Tryon extrapolated the idea of quantum fluctuations to the Universe as a whole. He reasoned that if all that existed was a quantum vacuum, a bubble-like energy fluctuation out of this vacuum could have given rise to the Universe. Tryon proposed that the whole Universe is the result of a vacuum fluctuation, originating from what we could call quantum nothingness.

Magnetic materials with a triangular lattice have been the focus of numerous research studies, as theoretical predictions suggest that they could exhibit spin liquid states. These are quantum phases of matter that present interesting characteristics, such as quantum entanglement and fractionalized excitations.

While there have been numerous experimental efforts aimed at observing these fascinating phases in materials with a triangular lattice, this has so far proved to be very challenging. A key reason for this is that weak spin-orbit coupling and other perturbations in these materials typically result in conventional spin freezing or magnetic states.

Researchers at University of California, Boston College, Oak Ridge National Laboratory and the National Institute of Standards and Technology were recently able to produce a quantum disordered ground state in the triangular lattice-magnet NaRuO_2. Their findings, published in Nature Physics, suggest that this state was enabled by the cooperative interplay between spin-orbit coupling and correlation effects in the magnetic material.

Scientists have found a way to restore the brain and spinal cord interface, developing an implantable device that enables paralyzed patient to stand and walk again.

A spinal cord injury (SCI) can be debilitating for some people, making it difficult for them to walk normally again. Some individuals may take weeks to recover their ability to walk after an injury, while others may take months or even suffer from paralysis.

This is mainly due to the SCI hindering communication between the brain and the region of the spinal cord responsible for limb movement.
