Photonics-based wireless link breaks speed records for data transmission      (via sciencedaily.com)     Original source 

Researchers demonstrated a 300 GHz-band wireless link that was able to transmit data over a single channel at a rate of 240 gigabits per second. The wireless communication system employs signal generators based on lasers that have ultra-low phase noise in the sub-terahertz band. This rate is the highest so far reported at these frequencies and is a substantial step forward in 300 GHz-band communications for 6G networks.

Decarbonizing the world's industries      (via sciencedaily.com)     Original source 

Harmful emissions from the industrial sector could be reduced by up to 85% across the world, according to new research. The sector, which includes iron and steel, chemicals, cement, and food and drink, emits around a quarter of global greenhouse gas (GHG) emissions -- planet-warming gases that result in climate change and extreme weather.

Artificial muscles -- lighter, safer, more robust      (via sciencedaily.com)     Original source 

Researchers have developed artificial muscles that are lighter, safer and more robust than their predecessors. The newly developed actuators have a novel type of shell structure and use a high-permittivity ferroelectric material that can store relatively large amounts of electrical energy. They therefore work with relatively low electrical voltage, are waterproof, more robust and safer to touch.

Sound-powered sensors stand to save millions of batteries      (via sciencedaily.com)     Original source 

Researchers are developing a new type of sensor that reacts to certain sound waves, causing it to vibrate. The sensor is a metamaterial that acquires its special properties through the structuring of the material. Passive sound-sensitive sensors could be used to monitor buildings, earthquakes or certain medical devices and save millions of batteries.

How to shift gears in a molecular motor      (via sciencedaily.com)     Original source 

Scientists have long strived to develop artificial molecular motors that can convert energy into directed motion. Researchers have now presented a solution to a challenging problem: how motion can be transferred in a controlled manner from one place to another through a 'molecular gear'. Molecular motors have the potential for use in, for example, energy storage applications and medicine.

Polymer power: Researchers enhance the safety of lithium batteries      (via sciencedaily.com)     Original source 

Lithium-ion batteries face safety concerns as a result of internal separator issues which often lead to short circuits. Scientists have now developed a method to improve the stability and properties of separators with a layer of silicon dioxide and other functional molecules. Batteries employing these separators demonstrated improved performance and reduced growth of disruptive root-like structures, paving the way for high-safety batteries that can aid the adoption of electric vehicles and advanced energy storage systems.

How macrophages regulate regenerative healing in spiny mice      (via sciencedaily.com)     Original source 

A team of researchers is delving deeper into the science behind how spiny mice can regenerate lost tissue and using what they learn to trigger regeneration in other types of mice -- advances which one day may be translated into humans. Whereas adult laboratory mice heal injuries with scar tissue, spiny mice have the unique ability to regrow lost skin and regenerate musculoskeletal tissues in their body.

Researchers pinpoint most likely source of HIV rebound infection      (via sciencedaily.com)     Original source 

Antiretroviral therapy (ART) does an excellent job at suppressing HIV to undetectable levels in the blood. However, small amounts of latent virus hide throughout the body, and when treatment is stopped, it opens the door for the virus to rebound. Researchers identified which tissues SIV, the nonhuman primate version of HIV, reemerges from first, just seven days after ART is stopped.

Liquid lithium on the walls of a fusion device helps the plasma within maintain a hot edge      (via sciencedaily.com)     Original source 

Emerging research suggests it may be easier to use fusion as a power source if liquid lithium is applied to the internal walls of the device housing the plasma. Past experiments studied solid lithium coatings and found they could enhance a plasma. The researchers were pleased they could yield similar results with liquid lithium, as it's better suited for use in a large-scale tokamak.

World's first successful embryo transfer in rhinos paves the way for saving the northern white rhinos from extinction      (via sciencedaily.com)     Original source 

Scientists have succeeded in achieving the world's first pregnancy of a rhinoceros after an embryo transfer. The southern white rhino embryo was produced in vitro from collected egg cells and sperm and transferred into a southern white rhino surrogate mother at the Ol Pejeta Conservancy in Kenya on September 24, 2023. The BioRescue team confirmed a pregnancy of 70 days with a well-developed 6.4 cm long male embryo. The successful embryo transfer and pregnancy are a proof of concept and allow to now safely move to the transfer of northern white rhino embryos -- a cornerstone in the mission to save the northern white rhino from extinction.
