External battery ZMI 20 Power Bank with 120W charger

29.12.2020

The Chinese company ZMI has introduced a new external battery ZMI 20 Power Bank, the main distinguishing feature of which was support for super-powerful fast charging at 120W. True, it is immediately worth noting that at the moment there is exactly one gadget on the market that can be recharged with such power - Xiaomi Mi 10 Pro Extreme Edition.

The capacity of the power bank is a mighty 25 mAh. This amount of energy is enough, for example, to recharge the iPhone SE (000) eight times.

There are two USB-C and one USB-A ports for connecting rechargeable devices. The total output power of the device is capable of reaching up to 200 watts. The ZMI 20 Power Bank itself only supports fast charging up to 65W. An external battery can reach 60% charge in an hour, and it will take 2 hours to fully charge it.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

Silk preserves blood cells at high temperatures 13.05.2016

Researchers at Tufts University in the US have found a way to stabilize blood samples for long periods of time without refrigeration - by encapsulating them in dry silk protein.

The scientists mixed purified silk protein powder extracted from silkworm cocoons with blood or plasma and dried the resulting mixture. The resulting films were stored at a temperature of 22-45 degrees Celsius. After a certain time, the blood samples were successfully restored by dissolving the film in water and are ready for analysis.

Blood biomarkers in this case can be successfully assessed even after storage for 84 days at temperatures up to 45 degrees Celsius. This provides better protection than the current approach of drying the sample on paper, especially at the elevated temperatures that can occur during overseas shipping and during the summer.

"This approach should facilitate the collection of outpatient blood tests for disease screening and monitoring purposes, especially for socially vulnerable populations, as well as to meet the needs of researchers and clinicians who do not have access to a centralized testing system. For example, the method will be useful for large-scale epidemiological studies in remote areas,” explains project leader David L. Kaplan.
