Cigarettes and alcohol lead to dementia

13.07.2013

In people who smoke and drink a lot, dementia occurs much faster, according to a study by psychiatrists at University College London (UK).

Many people know about the dangers of smoking and alcohol, about the dangerous diseases that bad habits cause. However, people do not always think that by smoking another cigarette or drinking another glass, they bring themselves closer to dementia or, simply speaking, dementia. Researchers have shown that smokers who also abuse alcohol develop dementia 36% faster than those who do not smoke and drink moderately.

Prior to this, researchers have already noted that smoking and alcohol separately contribute to the development of dementia. However, for the first time, psychiatrists drew attention to the combination of these factors, and found that the effect is really detrimental.

The research team evaluated 6473 adults (4635 men and 1838 women) aged 45 to 69 over a 10-year period. All participants were asked questions about their drinking habits and smoking frequency. Next, the researchers assessed cognitive functions - the ability to reason, solve simple mathematical problems, memory, speech development, etc. Similar cognitive tests were conducted three times during the ten-year study.

It turned out that in smokers who abuse alcohol, cognitive decline occurred 36% faster than in non-smokers and moderate drinkers. Simply put, their brains wore out faster. We can say that in ten years of research, the brains of heavy drinkers smokers were "worn out" as if 12 years had passed.

Scientists hope that the results of their study will make people think. The influence of alcohol and smoking is detrimental not only to the lungs and liver, but also to the brain. The combination of smoking and alcohol accelerates the development of dementia, and it is unlikely that anyone at a relatively young age of 60 wants to forget where they put the keys or the name of their grandson, just because in their young and mature years they could not refuse themselves in an extra glass and a cigarette.

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, ... >>

Anti-router Cyborg Unplug 14.09.2014

In today's digital era of wireless technologies, devices such as quadrocopters, as well as Google Glass glasses, along with other "smart" gadgets equipped with miniature cameras for discreet shooting, for some category of citizens are associated exclusively with espionage and illegal video recording.

The anti-router Cyborg Unplug will help you get rid of the obsessive feeling of persecution and the paranoia that develops against this background, which has every chance of becoming your personal guarantor of peace of mind. The task of the device is to automatically detect an unwanted device that has appeared in the coverage area of your Wi-Fi network, functionally focused on video shooting.

First, when scanning Wi-Fi bands with modules installed in wireless security cameras, smart glasses or drones, Cyborg Unplug identifies the type of device by its Mac address. If the electronics that have fallen into the range are banned at the direction of the owner of the router, then, as you might guess, the ability to access your wireless network is instantly blocked by the Mac address. Moreover, the specified procedure is carried out immediately before the trial connection attempt.

The presented anti-router is designed to monitor networks mainly in public places with a huge number of users in order to identify all potentially dangerous tracking devices with a working Wi-Fi module. When foreign equipment appears in the Cyborg Unplug coverage area, the device will notify its owner with a sound signal or a flashing LED. Everything else will happen without human intervention.

The author of the idea in the face of Julian Oliver provided two modes of Cyborg Unplug - "Territory Mode" and "All Out Mode". In the first option, the router with the prefix "anti" will filter out all devices located in the Wi-Fi network zone, allowing some of them to connect, and will begin to independently "catch" gadgets invading privacy. When "All Out Mode" is selected, the Cyborg Unplug blocking signal will include all equipment within range without exception.

The developers note that Cyborg Unplug does not interfere and does not, of course, affect the overall quality of the coverage. A flexible system of settings will even allow you to sort the found devices into categories and selectively block all Google Glass "smart" glasses without touching the same smartphones or laptops.

The cost of Cyborg Unplug, which will be available this year in two versions, will be $50 and $100, respectively. It is assumed that the main customers of Cyborg Unplug will not be individuals who can simply set a password for their home network, but the leadership of schools, restaurants and various kinds of enterprises. It is they who are interested in filtering, while leaving access to Wi-Fi open to everyone who wants to use the Internet for business or educational needs.
