The speech of sperm whales is similar to that of humans

18.05.2024

In the world of the ocean, where the mysterious and unknown coexists with the studied, sperm whales, with their huge brains, are of particular interest to science. Researchers, working with a huge array of audio recordings collected during the Dominica Sperm Whale Project (DSWP) - more than 8000 recordings, seek to unravel the secrets of their communication and understand the structure and complexity of the language of these mysterious creatures.

By studying in detail the recordings of 60 sperm whales in the eastern Caribbean, scientists have revealed surprising features of their communication, revealing the complexity of their language.

"Our observations indicate that these whales have a highly developed combinatorial communication system, including rubato and ornaments, which indicates their ability to quickly adapt and vary during communication. Despite significant differences in evolution, sperm whales have elements in their communication that are characteristic of human communication," says Shane Gero, a biologist at Carleton University and director of the CETI project.

Research has shown that sperm whales use codes that depend on the context of the conversation, making their vocalizations more expressive and structured than previously thought.

Scientists have already begun to develop a phonetic alphabet that, although it does not reveal the meaning of their conversations, allows them to be distinguished and rely on context for understanding.

“The use of machine learning methods plays a key role in identifying the characteristics of their communications and predicting the possible development of the dialogue. Our further research is aimed at uncovering the meaning of these communications and finding connections between the content of their conversations and social behavior,” emphasizes Daniela Rus from the Massachusetts Institute of Technology.

Work in the field of studying the speech of sperm whales not only helps us understand these amazing creatures, but also opens up new horizons for understanding the linguistic abilities of animals and the depths of the marine world.

Improving the efficiency of PbS quantum dot solar cells 14.06.2024

The latest solar technology research represents a significant breakthrough in improving the efficiency of PbS quantum dot solar cells. This method, based on the use of pulsed light, offers promise for simplifying the production and expanding the applications of these cells. A research team from the Daegu Gyeongbuk Institute of Science and Technology has developed an innovative method that uses pulsed light to improve the electrical conductivity of PbS solar cells. This method can significantly reduce the processing time required to achieve similar results. PbS quantum dot solar cells have significant potential in solar technology due to their photovoltaic properties. However, the formation of defects on their surface can reduce their performance. The new method helps suppress defect formation and improve electrical conductivity. Using strong light to complete the process ... >>

The power bank is also compatible with Huawei phones that support wireless charging. ... >>

Changes in a father's brain after the birth of a child 13.06.2024

A recent study conducted by scientists from the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences found interesting changes in the brains of men after becoming fathers. These changes were associated with involvement in child care, sleep problems, and mental health symptoms. Scientists found that men who became fathers experienced a loss of brain volume after giving birth. This volume loss was associated with greater involvement in parenting, sleep problems, and mental health symptoms. Researchers have found significant changes in men's brains between the prenatal and postnatal periods. In particular, there was a loss of gray matter volume, especially in parts of the brain responsible for higher functions such as language, memory, problem solving and decision making. Men who paid more attention to their children and spent more time with them lost more gray matter in their brains. This also affected their mental health ... >>

Smartwatch that analyzes the composition of sweat 13.06.2024

Scientists from the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences presented an innovative smartwatch that can analyze the composition of sweat. This device can be a valuable tool for athletes, allowing them to monitor changes in the body during training and competition. The device is equipped with various sensors that can process sweat from the human body and analyze the chemicals in its composition. Using sensors, you can accurately determine the levels of potassium, sodium and calcium ions. Sweat composition indicators can be monitored both in real time and over a period of six months. This allows athletes to receive continuous feedback on the state of their body during training and recovery. Smartwatch sensors are based on electrochemical methods and use a microfluidic chip that can process very small volumes of liquid. This makes it possible to study the composition of even 0,01 ml of sweat. Stability of sensors is a key aspect ... >>

Wine is safer than beer 12.06.2024

A University of Adelaide study has found that drinking alcohol in moderation may be less harmful to heart health than previously thought. Researchers have studied the effects of different types of alcohol on the risk of developing atrial fibrillation (AF), one of the most common forms of arrhythmia that can lead to serious heart complications. Atrial fibrillation is an irregular and rapid heartbeat that increases the risk of stroke, heart failure and other serious heart problems. Symptoms may include rapid heartbeat, shortness of breath, and weakness. Excessive alcohol consumption is known to increase the risk of developing AF, but the effect of small doses of alcohol remains unclear. The study was based on data from the UK Biobank, a large-scale database containing health information on half a million British volunteers. The study's lead author, Samuel Tu from the University of Adelaide's Center for Heart Rhythm Disorders, reports ... >>
