iPad is 5 degrees hotter

29.03.2012

Owners of the new iPad can say without exaggeration that their device has the most advanced screen on the tablet market and the most powerful graphics, but these innovations, unfortunately, have had a negative impact on other characteristics of the device: it has become heavier and larger, and a new study , conducted in Holland, suggests that another sacrifice in favor of innovation was increased heat transfer, an average of 5 degrees.

With a graphics load in the OpenGL test, the 2011 Apple tablet reaches 5 degrees after 28,3 minutes, while the new one reaches 33,6 degrees. It is worth noting that if both devices are in this mode lying on your knees or on open skin, it will not be very pleasant to hold them.

The hottest spot in both iPad models was the lower right corner, where the processor is located. The A5 in the iPad 2 comes with PowerVR SGX543MP2 graphics, while the A5X in Apple's new tablet comes with the SGX543MP4.

It is worth noting that both tablets have a special sensor that protects the device from overheating. If a certain temperature threshold is reached, the iPad will turn off. Apple says that the iPad can be used safely in temperatures up to 35 degrees.

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 ... >>

CIA in the fight against global warming 04.08.2013

The US Central Intelligence Agency is studying several projects that can reverse or at least slow down the negative processes of global warming. But so far, there are many questions about the participation of intelligence officers in potentially destructive activities.

American intelligence officers, together with NASA and specialists from the US National Academy of Sciences (NAS), launched a project to study several options for geoengineering intervention in the global climate of the planet in order to reduce or "cancel" the dangerous side effects of the technogenic activities of our civilization. Apparently, the involvement of the CIA means that the US government is seriously concerned that global warming could adversely affect international security, including the national security of the United States itself. In particular, in some regions, ice and snow cover may melt, which can lead to conflicts over new territories and sea routes. First of all, this concerns Russia and Canada. Also, wars and humanitarian crises can start because some large regions receive more rainfall and others less.

Geoengineering is an activity aimed at changing the climate of the entire planet or a vast region. The current NAS project has no such plans, at least not yet, but scientists and the CIA will spend $630 and 000 months studying options for such an impact on the planet. In particular, we mean options with the release of particles into the atmosphere that reflect sunlight or the creation of installations that absorb excess carbon dioxide. In addition to studying ways to combat global warming, the aim of the project is to assess the possible negative consequences of global warming.

It should be noted that earlier the CIA was already interested in the problem of global warming and even had a research center dealing with this problem. However, the center was closed last year by members of the US Congress who objected to the involvement of intelligence officers in such activities. It is not yet known how American politicians will react to the new CIA initiative, and whether individuals, public organizations and the media will be interested in this issue.

It should be noted that the US military and intelligence agencies have the greatest experience in climate change. In particular, during the Vietnam War, the US Air Force, in accordance with the plan of the CIA, not without success, caused heavy rains that washed away the guerrilla trails. Recently, many more large-scale geoengineering projects have appeared. For example, it is proposed to sow part of the ocean off the coast of Canada with plankton, which will "suck" carbon dioxide from the air.

Unfortunately, it is still difficult to assess the consequences of such serious interventions in the climate and the probability of causing an ecological catastrophe is high. A case is already known when businessman Russ George from California, secretly from the world community and by deceiving local residents, poured "feeding" for plankton into the Pacific Ocean - 110 tons of ferrous sulfate. According to him, this led to the blooming of plankton on an area of 10 thousand square meters. km. While the consequences of this unauthorized experiment are being studied (only a year has passed), scientists fear that irreparable damage may be caused to the nearby richest ecosystem of the Queen Charlotte Islands.
