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 ... >>

U.S. renewable power plants surpass coal-fired power 20.06.2019

In April, renewable energy plants outperformed coal-fired power plants for the first time in April, according to a report from the US Federal Energy Regulatory Commission (FERC). This means that they can now produce more clean energy, which is getting cheaper.

In 2016, coal lost its status as the king of the US energy industry in large part due to the so-called shale gas boom. A lot of cheap natural gas appeared in the states, which was used for energy purposes. In April this year, the total generating capacity of coal-based power plants amounted to 257,48 GW. The total installed capacity of renewable electricity, including sunlight, water flows, wind and geothermal heat, reached 257,53 GW.

Thus, the share of power plants based on renewable energy sources amounted to 21,56%, while the share of coal-fired power plants decreased from 23,04% to 21,55%. The difference is insignificant, but the fact itself is important, which suggests that this gap will increase in the coming months. The FERC report also notes that the share of green energy in the US is growing at an average of 1% annually, so by 2022 it will account for almost a quarter of all installed capacity in the states.

Meanwhile, American appetite for coal continues to decline. Since its peak in 2008, US coal consumption has hit its lowest level in 40 years, according to the US Energy Information Administration.
