Voice genetics: the key to hereditary timbre

17.06.2023

Researchers have discovered a gene responsible for the timbre of your voice - hoarse and low, or vice versa.

During the study, scientists analyzed speech recordings of almost 13 people and their genetic data. A piece of DNA called ABCC9 has been identified that is associated with higher voices in both men and women. The ABCC9 gene sequence is also linked to heart health.

Experts from the Icelandic company Decode Genetics emphasize that their data indicate a greater risk of heart problems in people with a higher timbre of voice.

Previous research has shown that men with a deep voice have higher testosterone levels, a more developed upper body, and are considered more attractive and dominant. Data analysis also showed that such men run large enterprises.

The researchers believe that the depth of male voices was most likely a factor in sexual selection in the past. In other words, men with deep voices had more sexual success.

Another gene, ABBC9, may also affect the pitch of the voice. It is associated with the work of the adrenal glands, which, in turn, produce steroids that turn into testosterone and other sex hormones. The latter directly affect the pitch of the voice.

According to the authors of the study, the gene responsible for the pitch of the voice may also be associated with high blood pressure and insufficient heart condition.

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, ... >>

Bus over the road 03.11.2010

The Beijing city government is set to implement an unusual project that should reduce traffic congestion by 30%: a bus on high "legs" that allow other vehicles to pass under it. Rails are laid along the sides of the road, and along them runs a long articulated structure with a ground clearance of more than two meters and a width of up to six meters, accommodating 1200-1400 passengers.

Cars will be able to pass under this "superbus". Of course, special stopping pavilions will have to be built on the road, corresponding to the height of the floor of a giant bus. And the road itself should be as straight as possible, without slopes and not have bridges below five meters.

In the near future, they promise to lay an experimental section of such a road six kilometers long in the west of the Chinese capital.

If the tests are successful, in two years the total length of roads suitable for the "superbus" will be 186 kilometers. This will include the route to Beijing International Airport. It would cost ten times less to build this network than to build subway lines of the same length.
