Fires in the Amazonian forests have accelerated the melting of glaciers in the Andes

03.12.2019

Observations of ice conditions in the Andes have shown that massive fires in the Amazon jungle over the past ten years have accelerated their melting by 5%. The strength of their action in the coming years will more than double due to the fact that the scale of fires is increasing, and the concentration of dust in the atmosphere is growing.

"The forecasts of the UN Intergovernmental Panel on Climate Change (IPCC) indicate that the Amazon will become much drier in the coming decades and centuries. Therefore, fires in the southwest of this region have already become not a local, but a continental problem that can deprive residents of water many parts of the Andes," scientists say.

Ecologists estimate that the Amazonian rainforest covers about 5,5 million square kilometers. km. They account for about 10% of the carbon stored in all living organisms on Earth and a similar amount of biomass produced each year. In addition, they produce approximately 6% of the total oxygen released by all photosynthetic organisms.

Such a serious role of this region in the life of the planet makes climatologists and ecologists closely monitor its fate for almost half a century. They do this with climate satellites, ground weather stations, and other observational techniques. Measurements of recent years make researchers seriously worry about the fate of the Amazonian forests.

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, ... >>

Sunswift 7 high-speed electric car 23.12.2022

A team of engineers from Australia are claiming a new world record for their Sunswift 7 electric vehicle. The solar-powered vehicle has been tested to cover 1000 km on a single charge in less than 12 hours.

The Sunswift 7 electric car weighs only 500 kg. That's about a quarter of the weight of a typical Tesla car. To invest in such a small weight limit, engineers had to abandon the air conditioning system, ABS brakes, airbags, wipers and other features familiar to production cars. Instead, engineers focused on aerodynamic efficiency and rolling resistance. If the Tesla Model S has a drag coefficient of 0,208, then the Sunswift 7 has a drag coefficient of only 0,095.

The team spent two years building the Sunswift 7 with the goal of setting a Guinness World Record and demonstrating the fastest solar-powered electric vehicle that can travel over 1000 km. A record attempt was made recently at the Highway Circuit test track at the Australian Automotive Research Centre, when the Sunswift 7 covered 240 laps on a single charge.

It took 1000 hours 11 minutes and 53 seconds to cover the 32 km distance, and the average speed was 85 km/h. Drivers changed every few hours. On the way to the finish line, the team had to solve several problems: battery management and a punctured tire.

So far, Sunswift 7 is unofficially considered the fastest electric car, covering more than 1000 km without recharging. The team is awaiting official confirmation of time and vehicle telemetry data in order to receive a Guinness World Record certificate.

"Within this record, energy consumption was only 3,8 kWh/100 km, while today even the most efficient electric vehicles on the road only achieve a rating of 15 kWh/100 km, with an average of around 20 kWh/100 km," said the CEO. Team Professor Richard Hopkins.
