Remote controlled female contraceptive

08.07.2014

Massachusetts-based MicroCHIPS has developed an electronic contraceptive for women that can be turned on and off wirelessly, reports Technology Review.

Implanted under the skin on the buttock, upper arm or abdomen, the 20x20x7mm device contains a microchip and a tiny reservoir filled with a hormone called levonorgestrel, widely used in modern female contraception.

The tank is equipped with a titanium-platinum membrane, which softens under the influence of electric current and passes the active substance. The device injects 30 micrograms of levonorgestrel into the woman's body every day. "Creating such an airtight membrane has been one of the biggest challenges for us," said MicroCHIPS President Robert Farra.

The device is equipped with its own battery and is able to work and provide pregnancy control continuously for 16 years, that is, for half of a woman's reproductive cycle. None of the modern contraceptives has a service life of more than 5 years, the creators emphasize.

But service life is only one of the advantages of the invention. You can turn the device on and off remotely. The doctor can remotely, without visiting the hospital, change the dose of the administered hormone, taking into account the characteristics of the patient's body.

An electronic contraceptive is currently undergoing clinical trials. It is implanted under the skin using a local anesthetic. The procedure takes about half an hour. The device has proven itself in terms of reliability and lack of reaction to rejection.

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 ... >>

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, ... >>
