Centuries-old lotus sprouts

09.05.2002

Botanists found 20 lotus seeds in muddy deposits at the bottom of a lake in the Chinese province of Liaoning.

Judging by the growth rate of the sedimentary stratum and according to radiocarbon dating, these seeds are from 200 to 500 years old. Four seeds gave rise to seedlings, and then to adult plants. True, the centuries spent in the depths of the soil affected the appearance of lotuses: due to mutations, the shape of some leaves is distorted, the stem is weakened, and the color of the flowers is changed.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

NetApp AFF8000 Flash Arrays 15.07.2015

NetApp has expanded its all-flash storage array lineup with new models specifically designed for enterprise customers. The All Flash FAS (AFF) 8000 series provides the capabilities required for the widespread adoption of flash systems. Customers will also benefit from a fast, long-term ROI with the ability to seamlessly move data as it ages from flash to disk and to the cloud.

Four models of the AFF8000 are available on the market today and can be ordered as standalone systems or as FlexPod Converged Infrastructure components. Professional support services from NetApp and its partners can help you determine the workloads that flash systems can best handle.

"The AFF8000 line is designed to bring high-performance flash storage to the mainstream market," said Lee Caswell, vice president of product and solution marketing for NetApp. "We help customers achieve long-term success by offering with a comprehensive set of enterprise features and the ability to move data from disk to the cloud as tasks change."

The AFF8000 series provides built-in data security, multi-protocol support, and scalable performance. Other capabilities of the AFF8000 solutions include NetApp's multi-tenancy and application integration, which makes it easy to set up and manage databases, virtual servers, and VDI workloads.

All Flash FAS incorporates software enhancements developed by the experienced NetApp Advanced Technology Lab. New developments include a flash-optimized read data path, data compression as it enters the storage system, and data deduplication before it is written to disk. FlashEssentials is a component of the clustered Data ONTAP system that powers NetApp's next-generation data management strategy, the Data Fabric. The NetApp approach allows customers to define and control how data is managed, protected, and moved from flash to disk and to the cloud.
