Friday Lock smart door lock

07.05.2017

Friday Labs announced the availability of the Friday Lock smart door lock, which was announced and funded through Indiegogo back in 2015.

The fact that the developers missed the deadlines is, of course, not very good, but at least they did not refuse to fulfill their obligations. Those who supported the developers have already received their locks. Others can pre-order for $249 and ship in 3-4 weeks.

The device supports smartphones running iOS and Android operating systems. It is equipped with Wi-Fi and Bluetooth modules, and also supports the Apple HomeKit platform. The corresponding application will automatically close the door behind you and open it when you are close. You can also send messages to friends with a guest pass that will allow them to open the door once.

The Friday Lock will last about three months before you need to recharge the built-in battery.

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 ... >>

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, ... >>

Fats are burned in the evenings 22.11.2018

Our body obeys daily rhythms in everything, and metabolism is, of course, no exception here: organ systems work differently at different times of the day, and therefore energy consumption will also be different. Harvard researchers found that at different times of the day, our bodies burn different amounts of calories using different resources.

Scientists set up the following experiment with seven volunteers: they had to sit in a room without windows for three weeks, not knowing what time of day it was; every day they went to bed four hours later than the day before - as if they were traveling through time zones around the world. And they all measured how many calories the body burns at rest at different times of the day and night.

Thanks to the simulation of traveling around the world, it was possible to clearly see the schedule of energy expenditure. In all, the metabolism was clearly subject to the biological clock, although with individual characteristics. Overall, 129 more calories were burned in the afternoon and evening than in the morning, with an average peak occurring at about 5 p.m. - although for some, this metabolic peak occurred at 2 p.m. or even at 8 p.m. The body spent the least amount of energy early in the morning, around 5 o'clock, although again there were volunteers with a minimum at 2 am and 8 am.

There is nothing surprising in such a spread, after all, we all know very well that different people have different chronotypes, someone is more active in the morning, someone in the afternoon, someone in the evening. And, as it was said, at different times of the day the body takes calories from different substances: if carbohydrates are spent most of all in the morning, then in the evening mainly fats are sent to the metabolic furnace.
