Cleaning up environmental contaminants with quantum dot technology      (via sciencedaily.com)     Original source 

The 2023 Nobel Prize in Chemistry was focused on quantum dots -- objects so tiny, they're controlled by the strange rules of quantum physics. Quantum dots used in electronics are often toxic, but their nontoxic counterparts are being explored for uses in medicine and in the environment, including water decontamination. One team of researchers has specially designed carbon- and sulfur-based dots for these environmental applications.

Quantum talk with magnetic disks      (via sciencedaily.com)     Original source 

Quantum computers promise to tackle some of the most challenging problems facing humanity today. While much attention has been directed towards the computation of quantum information, the transduction of information within quantum networks is equally crucial in materializing the potential of this new technology. Addressing this need, a research team is now introducing a new approach for transducing quantum information: the team has manipulated quantum bits, so called qubits, by harnessing the magnetic field of magnons -- wave-like excitations in a magnetic material -- that occur within microscopic magnetic disks.

Robotic metamaterial: An endless domino effect      (via sciencedaily.com)     Original source 

If it walks like a particle, and talks like a particle... it may still not be a particle. A topological soliton is a special type of wave or dislocation which behaves like a particle: it can move around but cannot spread out and disappear like you would expect from, say, a ripple on the surface of a pond. Researchers now demonstrate the atypical behavior of topological solitons in a robotic metamaterial, something which in the future may be used to control how robots move, sense their surroundings and communicate.

Crawfish could transfer ionic lithium from their environment into food chain      (via sciencedaily.com)     Original source 

Lithium-ion rechargeable batteries are showing up in ever more devices, and the increasing use of this technology means more lithium is expected to find its way into the environment as a contaminant. In new research, a team has explored how this ion accumulates in a common Southern crustacean, the crawfish, with implications for the environment and public health.

Is food waste the key to sustainable, plastic-free diapers and sanitary pads?      (via sciencedaily.com)     Original source 

Once thrown away, disposable diapers and sanitary pads can take hundreds of years to decompose, because they contain plastics and other synthetic polymers. But now, researchers are replacing these materials with components made from protein biomass that is often discarded. They are sustainable and biodegradable, and they could potentially allow future diapers and pads to be flushed down a toilet or used as fertilizer.

Molecular crystal motors move like microbes when exposed to light      (via sciencedaily.com)     Original source 

At first glance, Rabih Al-Kaysi's molecular motors look like the microscopic worms you'd see in a drop of pond water. But these wriggling ribbons are not alive; they're made from crystallized molecules that perform coordinated movements when exposed to light. With continued development, these tiny machines could be used as drug-delivery robots or engineered into arrays that direct the flow of water around submarines.

Empty 'backpacks' activate the immune system against cancer      (via sciencedaily.com)     Original source 

Researchers have discovered that the mere act of attaching their microparticle 'backpacks' to neutrophils is enough to activate them against cancer -- no drugs needed. In experiments, backpack-bearing neutrophils shrank tumors and extended the survival of mice with cancer, and treated animals retained an immune memory of the disease. This approach opens the door to a new class of drug-free immunotherapy for cancer.

New ultrasound technology may revolutionize respiratory disease diagnoses      (via sciencedaily.com)     Original source 

By evaluating sound vibrations produced by the airflow induced within the lungs and bronchial tree during normal breathing as well as those produced by the larynx during vocalizations, doctors can identify potential disease-related abnormalities within the respiratory system. Researchers demonstrate the efficacy of ultrasound technology to detect low-amplitude movements produced by vocalizations at the surface of the chest. They also demonstrated the possibility of using the airborne ultrasound surface motion camera to map these vibrations during short durations so as to illustrate their evolution.

Harnessing hydrogen at life's origin      (via sciencedaily.com)     Original source 

A new report uncovers how hydrogen gas, the energy of the future, provided energy in the past, at the origin of life 4 billion years ago. Hydrogen gas is clean fuel. It burns with oxygen in the air to provide energy with no CO2. Hydrogen is a key to sustainable energy for the future. Though humans are just now coming to realize the benefits of hydrogen gas (H2 in chemical shorthand), microbes have known that H2 is good fuel for as long as there has been life on Earth. Hydrogen is ancient energy.

Two artificial intelligences talk to each other      (via sciencedaily.com)     Original source 

Performing a new task based solely on verbal or written instructions, and then describing it to others so that they can reproduce it, is a cornerstone of human communication that still resists artificial intelligence (AI). A team has succeeded in modelling an artificial neural network capable of this cognitive prowess. After learning and performing a series of basic tasks, this AI was able to provide a linguistic description of them to a 'sister' AI, which in turn performed them.

Holographic message encoded in simple plastic      (via sciencedaily.com)     Original source 

Important data can be stored and concealed quite easily in ordinary plastic using 3D printers and terahertz radiation, scientists show. Holography can be done quite easily: A 3D printer can be used to produce a panel from normal plastic in which a QR code can be stored, for example. The message is read using terahertz rays -- electromagnetic radiation that is invisible to the human eye.
