Lawn mower against crime

08.03.2018

Researchers from Columbia University (USA) found that tidying up wastelands in poor areas of the metropolis significantly reduces the level of crime in these areas.

Abandoned plots of land, overgrown with grass and littered with garbage, make up to 15% in US cities, scientists have calculated. Often such wastelands are chosen by criminals for drug trafficking and consumption, for escape and shelter from the police.

Scientists, together with the Pennsylvania Horticultural Society and the Philadelphia Department of Housing, decided to try to clean up these areas and see how such changes would affect the crime rate in nearby areas.

Specialists managed to put in order hundreds of wastelands. Some of them underwent large-scale processing - they were cleared of debris, the soil was leveled, new grass was planted, small fences were put up around the perimeter. On others, only garbage was removed and the grass was mowed. Next, the scientists compared data on crime in the areas where the work took place, and where the wastelands remained the same as before. To do this, they studied police reports and conducted a survey of residents of the areas closest to the wastelands before and after improvement.

Even a minor improvement helped to reduce crime somewhat, by about 10%. In areas where the population lived below the poverty line, this figure was already 13%, and crimes with the use of firearms decreased by 30%. Residents of the districts also reported that they began to feel more secure.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

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, ... >>

Spider venom will save you from a heart attack 03.08.2021

The bite of a funnel-shaped spider that lives on the Australian Fraser Island is fatal. But the spider's venom could also be a lifesaver - scientists have developed a drug candidate based on a molecule found in the venom of funnel-web spiders. Drugs based on this molecule could be used to treat patients with a heart attack.

Australian scientists have tested the Hi1a protein as a drug candidate to prevent the death of heart cells. A heart attack causes oxygen deficiency, which leads to the oxidation of the environment of the cell. In fact, this becomes a signal for cells to die. However, a protein from the Hi1a spider venom can stop this signal from being sent.

Funnel-web spiders are poisonous, but thanks to modern first aid methods and antidotes, no one has died from them lately. However, spider venom is a very effective compound that scientists want to use to save lives. So far, there are no drugs that could stop the transmission of the aforementioned signal. This means that Hi1a could save hundreds of thousands of heart attacks and transplant patients.

Cell engraftment is important in heart transplantation. Hi1a can reduce cell death and make heart transport and transplantation more successful. The scientists tested the Hi1a protein on beating human heart cells and found an improvement in their survival.

Professor Peter McDonald, one of the authors of the study, says: "Normally, if a donor heart stops beating for more than 30 minutes before extraction, it is no longer usable. And if we can get an extra 10 minutes, it will make a huge difference. For people who are literally standing on the verge of death, it can bring back life."

In a heart attack, Hi1a can be given as an injection as first aid. Such a drug will significantly improve the outcome of a heart attack and increase survival. This will be of particular importance for residents of rural areas, where the road to the nearest hospitals is usually very long.

Poisons have long been successfully used in medicine. Various snake venoms are used in the treatment of heart diseases and in the form of painkillers. These are very powerful compounds that scientists are learning to use for peaceful purposes, and not as laid down by nature.
