The desire to hug is in women's genes.

12.07.2020

The tendency to show sympathy can be genetically determined. At least this applies to the female half of the population, scientists at the University of Arizona found out.

The experiment involved 464 pairs of twins aged 19 to 84 years. About half were homozygous (from one egg), the other half were heterozygous (from different). Homozygous twins have 100% of common genes, heterozygous twins have 50%.

Each subject rated on a nine-point scale a number of statements related to the manifestation of sympathy. Thus, it was revealed which behavior is characteristic of certain participants, and which is not. The results were analyzed for the similarity of the responses of each pair of twins. And it turned out that homozytic pairs scored more points than heterozytic ones, and the differences in manifestations of sympathy affected only female pairs of twins. The results of men among homo- and heterozygous twins did not differ.

Scientists have come to the conclusion that the tendency to affectionate behavior in women is genetically determined by about 45%. However, the results of the study are more about population-level differences than differences between individuals. That is, this does not mean that the tendency to embrace absolutely every woman is 45% due to heredity, and 55% due to the environment. And predisposition to certain types of behavior does not mean that all people are guaranteed to behave in one way or another.

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, ... >>

Created an artificial pancreas 25.02.2020

Canadian scientists at McGill University in Montreal have created a new artificial pancreas system that will provide vital support for people living with type 1 diabetes.

Insulin pumps have been around for over 30 years. Using these portable devices, people living with diabetes manually select the dose of insulin they need, which is then pumped into the bloodstream. Despite the fact that most patients already use automatic glucose monitors to monitor their blood glucose levels, and do not prick their fingers every time, as they used to, few people manage to maintain glucose targets for a long time. Some people are in a state of hyperglycemia most of the time, accompanied by headaches and weakness, while others regularly experience hypoglycemia, which causes dizziness, confusion and impaired speech.

Scientists at McGill University have developed a "smart" insulin pump, an artificial pancreas with the ability to eliminate high and low glucose levels that reduce quality of life and can cause long-term health complications.

Study leader Dr. Ahmad Haidar began his work when the first commercially available automated glucose sensors were first available. Dr. Haidar has developed an algorithm that, based on the readings from the sensor, tells the insulin pump how much insulin to inject.

"It was a wonderful coincidence," the scientist said in a press release, "because the automatic sensor made it possible to create an artificial pancreas system."

Today, McGill University's Artificial Pancreas Laboratory has 12 full-time researchers and 45 external employees working on the creation of an artificial organ. This is the only scientific team in Canada involved in such developments.

Many of the results obtained in the laboratory are unique. In particular, scientists conducted an experiment on the delivery of the second hormone - pramlintide. The researchers expect that the combined action of pramlintide and insulin will be more effective than insulin alone.
