Currently, the U.S. military is studying a technology that can “reprogram” the cells of injured soldiers so that they have the ability to heal wounds quickly similar to the protagonist of the science fiction film “Wolverine”, and the wound healing speed is 5 times faster than that of ordinary people. . It is reported that the principle of the therapy is to reprogram the cell sequence by modifying the cell gene so that it becomes a different type of cell when necessary.
In the process of “programming” cells, scientists use proteins called “transcription factors” to modify their genomes. These transcription factors regulate different genes, such as cell division and growth, as well as cell migration and tissue regeneration. Transcription factors can directly act on the wound by means of “spray bandages” to convert muscle cells exposed in deep wounds into superficial skin cells covering the wound, so that the wound can heal faster.
According to estimates, the current energy consumption of data centers has reached 2% of global electricity, and this figure may rise to 8% within 10 years. To reverse this trend, scientists are considering simplifying microprocessors in data centers in new ways. Japanese researchers took this idea to the extreme and created a superconducting microprocessor with zero resistance.
This new microprocessor prototype is called MANA (Single Adiabatic Integrated Architecture) and is the world’s first adiabatic superconductor microprocessor. It is composed of superconducting niobium and relies on hardware components called “adiabatic quantum flux parametric electrons (AQFP)”. Each AQFP consists of several fast-acting Josephson junction switches, which require very little energy to support superconductor electronics. The MANA microprocessor is composed of more than 20,000 Josephson junctions.
It is well known that compost made from food waste helps plants grow. Recently, American scientists have used food waste to ferment to create a liquid fertilizer that can increase the number of beneficial bacteria in the plant itself and its soil.
The researchers started the experiment with two types of food waste (the glutinous rice left over from the beer production process and the mixed food discarded by the grocery store). The liquid obtained by anaerobic fermentation is added to the water used for irrigating citrus plants in the greenhouse. This is a closed-loop irrigation system in which the water flowing out of the soil is pumped back to the original road for reuse.
In just 24 hours after adding liquid fertilizer, the researchers found that the number of beneficial bacteria in plants and soil was 2 to 3 orders of magnitude more than that in the control group. This liquid fertilizer not only helps plants grow stronger and faster, but also enhances plant resistance to diseases.
