What are the reasons for the appearance of ghost islands on geographical maps?

During the time of the Great Geographical Discoveries, a large number of islands and reefs were mapped, the existence of which was subsequently not confirmed. The most famous example is Tabor Island, aka Maria Theresa Reef, which is supposedly located in the South Pacific Ocean. The heroes of Jules Verne's novels "Children of Captain Grant" and "The Mysterious Island" turn out to be on it, and the writer himself was sincerely convinced of the reality of the island. Already in the middle of the 20th century, his search was unsuccessful, but the reef continues to be depicted on some modern maps. There are several reasons for the appearance of ghost islands: sailors mistake icebergs, mirages, and floating formations of volcanic pumice for land, which can acquire vegetation and bird nests.

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 ... >>

VESA VDC-M compression standard 17.05.2018

VESA has introduced Display Compression-M (VDC-M) - a new compression standard for interfaces for connecting built-in displays of mobile devices, including smartphones.

Developed in collaboration with MIPI, it provides higher compression (up to 5:1) than the VESA Display Stream Compression (DSC) standard, which provides compression up to 3:1. At the same time, "no visible loss of quality" is maintained. The payoff for increasing the compression ratio is the complication of the scheme. VDC-M is the third in a family that also includes DSC 1.1 introduced in 2014 and DSC 1.2 published in 2017.

The need for a new codec is caused by an increase in the resolution of displays. The association hopes that VDC-M will find the same wide application as its predecessors. MIPI is already planning to include VDC-M in a future specification for mobile displays.
