CAMM is the new standard for ultrabook RAM

07.05.2022

Dell has developed an original alternative to the SO-DIMM standard, which has not changed for many years, and is well known to owners of laptops and mini PCs. The new form factor is designed to reduce the thickness of modern laptops and the number of connectors on their motherboards without sacrificing performance.

CAMM modules (Compression Attached Memory Module) differ from the usual solutions primarily in size. Due to the use of a flat contact pad, they are 57% thinner, which allows them to be installed in compact ultrabooks, replacing two traditional ones with one universal bar. The memory capacity of new products (DDR5 standard, effective frequency up to 4800 MHz) can range from 16 to 128 GB, while older models will be dual-rank.

Each CAMM also includes its own Programmable Memory Chip (PMIC). The company has already stated that the new standard will not be closed - other laptop manufacturers will be able to use it.

The proprietary connector, if necessary, can be "converted" to a standard SO-DIMM using a special adapter.

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 ... >>

Statin on a bioconveyor 26.04.2015

Statins are substances that inhibit a key enzyme that produces so-called bad cholesterol. Accordingly, its content in the blood falls, and with it the risk of atherosclerosis. A natural statin called compactin is found in mushrooms and was isolated by Endo Akiro in the mid-70s from a mold. However, it is inconvenient for pharmacists.

In the 80s, another statin, lovastatin, was discovered. It was also found in higher fungi, such as oyster mushrooms. In order not to force the population to eat huge amounts of mushrooms, chemists have come up with methods for synthesizing statins, and many doctors consider this the most important public health achievement in the last twenty years.

Synthesis, however, is complex and expensive, it involves several steps and subsequent purification. Biotechnology from the University of Manchester and DSM's Delft Biotechnology Center, led by Christie McLean and Marco van den Berg, managed to do it all in one step.

To do this, they reprogrammed an industrial strain of the mold Penicillium chrysogenum that produces antibiotics. First, the gene responsible for the decomposition of compactin was removed from it. Then they inserted the genes necessary for the efficient synthesis of compactin. Then they forced him to synthesize also cytochrome P450 of the bacterium Amycolatopsis orientalis, this protein turns compactin into one of the most effective statins - pravastatin. But this transformation went very badly, because the result was a mixture of stereoisomers, which are very expensive to separate.

The properties of cytochrome were altered by artificial selection, and eventually a process was achieved that synthesized the purest stereoisomer of pravastatin at six grams per liter of culture. This can already be implemented in production.
