Sleep is directly linked to being overweight.

02.02.2017

As it became known to scientists from the Australian University of Diabetes in Melbourne, when a person loses excess weight, his sleep improves.

It is a known fact that people suffering from obesity have problems with night rest. But as soon as a person gets rid of excess weight, his sleep improves and its duration increases. Specialists were interested in the effect of losing weight on sleep during the daytime, and therefore they conducted 42 studies.

Volunteers who suffered from obesity were involved in this scientific work. It was found that active weight loss is accompanied by drowsiness, especially during the daytime. The same condition is experienced by people who decide to get rid of extra pounds with the help of surgery. Experts have found that the more a person loses weight, the more he wants to sleep.

Scientists suggest that the results of this scientific work will help in the fight against obesity.

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

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 ... >>

8Gb LPDDR4 mobile DRAM chip 26.01.2014

South Korean electronics manufacturer Samsung Electronics has announced the first ever 8Gb LPDDR4 DRAM chip for smartphones and tablets.

"The new generation of memory chips supporting the LPDDR4 interface is making a significant contribution to the development of the global mobile DRAM market, as the LPDDR4 standard will soon become dominant," said Young-Hyun Jun, executive vice president of sales and "We will continue to introduce the most advanced DRAM memory modules that are one step ahead of other products, enabling OEMs to deliver innovative mobile devices to users in a timely manner."

The new 8Gb high-speed LPDDR4 DRAM chip delivers high levels of performance and power efficiency, ensuring fast mobile applications and ultra-high resolution screens on mobile devices while minimizing power consumption.

The 8Gb LPDDR4 chip is made using a 20nm process and has the highest storage density of any memory chip to date. Thanks to four 8 Gb chips assembled in one package, mobile device manufacturers get the opportunity to immediately install 4 GB of LPDDR4 RAM in one module. This will allow mobile devices to reach new heights of performance without sacrificing either size or power consumption.

It is worth noting that Samsung 8Gb LPDDR4 memory uses the new LVSTL (Low Voltage Swing Terminated Logic) I/O interface, which was first proposed to the JEDEC committee by Samsung and subsequently became the standard for LPDDR4 DRAM memory. Based on the new interface, the LPDDR4 chip is capable of delivering data transfer rates of 3200 Mbps per pin, which is twice the performance of the previous generation LPDDR3 DRAM in the 20 nm class. In addition, the new interface consumes 40% less power at an operating voltage of 1,1 V.

With the release of the new chip, Samsung will focus on the premium segment of the mobile market, which includes smartphones with large UHD screens, tablets and ultra-thin laptops with a screen resolution four times higher than previous models. The chip will also be used in high-performance network systems.
