Population and climate of the planet

06.11.2012

Using census data and weather data (temperature and precipitation) collected in about 3000 US counties over a century, Jason Samson and colleagues were able to demonstrate a strong relationship between climate and population growth. What's more, in a study published in PLOS ONE, the researchers found that population changes were more strongly associated with climate than with income, urbanization, or food production.

According to the study, today's average American lives in a drier and warmer (by 1.5°C) climate than a hundred years ago. More and more people live in the southern part of the country, stretching from California to Florida and including major cities, including Austin - the third largest city in the country in terms of population growth in 2000-2006. Separately, the researchers noted the fact that demographic growth and urbanization in these warmer and drier climatic zones increased their pace throughout the 30th century and became especially noticeable in the last XNUMX years.

Although the authors were able to show such a significant relationship between climatic conditions and population growth, they caution against using climate as a major determinant in population migration predictions. At the same time, the researchers suggest carefully studying this information and using it in demographic policy when building plans for the future in the context of global climate change.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

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 ... >>

Mother's milk and career 11.01.2008

British sociologists from the University of Bristol, following the fate of 1400 children born in Bristol between 1937 and 1939, came to the conclusion that breastfeeding later reflects well on a child's career.

Of those who were breastfed in infancy, most have climbed the social ladder compared to their parents, and of the "artists" only half have achieved this. Moreover, the chances of success in life are higher, the longer the child was not weaned. Such differences are also noted within the same family: if one child was breast-fed, and the other with substitutes, then greater success in life, as a rule, awaits the first.

The reasons for this phenomenon are unclear, although it has been observed that naturally fed children have a slightly higher IQ.
