Multi-color marker Colorpik Pen

04.09.2023

An innovative product from the American startup Colorpik is a felt-tip pen that can create a palette of 16 million colors by extracting color information from the environment.

This device is equipped with a high-precision RGB sensor and four replaceable ink cartridges filled with ink of different base colors.

Using the Colorpik Pen is incredibly simple: you just need to bring the marker to the object of interest in the color and activate the button on the body. The built-in pump instantly mixes the ink, creating the desired shade. The felt-tip pen is able to scan absolutely everything - be it a flower petal, a car, a leather jacket and much more.

The Colorpik Pen comes with six different interchangeable nibs (ball, marker, brush, fluffy, round and stylus) and comes with a stylus cap perfect for use on touch devices.

In addition, the marker can interact with your smartphone through a special mobile application for iOS and Android. In this application, you can adjust and complement the color scheme as you wish. Information can also be transferred to a tablet or computer via Bluetooth and USB.

The manufacturer claims that the built-in 280 mAh lithium battery will last for 15 hours of active use, and one cartridge is enough to create a line 24 kilometers long.

The Colorpik Pen is already available on Kickstarter for $149. The kit includes the marker itself, four replacement nibs, a color palette, a charging cable and three sets of ink cartridges.

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, ... >>

Established the connection of odors with memories 06.08.2018

Neuroscientists at the University of Toronto have described how the brain works to form vivid memories that include smells and associated associations.

The process of forming complex memories is associated with the interaction of the hippocampus and the anterior olfactory nucleus (anterior olfactory nucleus, AON), located in the forebrain. The hippocampus is responsible for the consolidation of memories, that is, the process of their transition from short-term memory to long-term memory. The hippocampus also provides spatial memory - stores information that allows you to navigate the terrain. AON plays an important role in the perception of aromas, but remains poorly understood.

To investigate the role of the AON and the hippocampus in memory formation, the authors of the new work used the tendency of mice to carefully sniff unfamiliar odors and pay little attention to familiar odors. When mice forget a certain smell, it again begins to arouse interest in rodents.

During the experiments, the animals were placed in cages containing containers with various flavors: the smells of garlic, banana, coffee, and other products. At the first stage of the experiment, the mouse was placed in a cage with two containers with different odors, then the animal was placed in a medium with two identical samples. Rodents, in which scientists artificially "turned off" the neural pathways connecting the AON and the hippocampus, studied both duplicate odors for the same length of time - they did not remember the first sample. The control group of mice quickly identified the repetition and did not pay attention to the second container.

In the following experiments, mice were attracted not only by the novelty of the smell, but also by the changed position of one of the containers or the new sequence of containers in the room. At the same time, rodents with damaged connections between the AON and the hippocampus still did not notice the difference between the new and old environments.

Earlier studies have shown that loss of the ability to distinguish smells may be one of the early symptoms of Alzheimer's disease, and AON is rapidly degraded in the early stages of the disease. The new data can be used to create more effective diagnostic tests.
