Miniature laptop charger

04.01.2014

FINsix Corporation (USA) has introduced a charger (charger) for laptops, comparable in size to the "charger" for mobile devices.

The device is combined in one housing with a plug. It is four times smaller and six times lighter than traditional laptop memory, according to the manufacturer.

Device power - 65 watts. It provides not only a cable for a laptop, but also a USB connector for charging tablets and smartphones. Moreover, a mobile device and a laptop can be charged at the same time.

It was possible to reduce the size of the charger thanks to the use of a high-frequency current converter operating in the range of 30-300 MHz, as well as the technology developed in FINsix to minimize power leakage.

The new charger will be unveiled in January at CES in Las Vegas. Sales of the device are planned for the middle of 2014.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

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 ... >>

Biochemical Reboot of the Eye: Treating Blindness 14.04.2017

Light-sensitive pigments, which are found in everyone from bacteria to vertebrates, can be reset by biomechanical manipulations and thereby restore people's vision.

Scientists at the Western Reserve School of Medicine, USA have used a modified form of vitamin A to initiate a reset mechanism and restart the proteins needed for human vision. The target protein was photosensitive rhodopsin, which belongs to a family of proteins found in cell membranes that transmit an external signal to the internal cellular system. The discovery provides new opportunities for creating modified retinas that will improve vision.

The discovery delves into the biochemistry of vision, to why the chemical configuration of the retina is important for human light perception. Humans see with the help of a highly sensitive protein, rhodopsin, which attaches to retinal molecules to sense light. Photons of light enter the eye and are absorbed by the retinal-rhodopsin complex, activating the downstream signaling cascade that makes up vision.

It is especially important that the retina waits for light in one chemical configuration, and after absorption it changes into another one called all-trans retinal. But this transformation is unidirectional, and many specialized proteins are needed to return the retina to its first configuration. Inherited mutations in any of these can cause degenerative retinal diseases. Researchers who want to cure such diseases must either correct or bypass the altered proteins.

Researchers have discovered a self-renewing mechanism in bovine rhodopsin that is extremely similar to human. They used the purified proteins in the lab to show how their modified retina binds to bovine rhodopsin, successfully activates human proteins when exposed to light, and after signaling with thermal energy alone, slowly reverts to an inactive form that can be reactivated by photons. The discovery suggests that retinal molecules with a specific chemical structure can stimulate rhodopsin, which is needed for human vision, which means that mutated proteins can be bypassed and restore people's vision.
