Very early classes have a negative impact on student achievement

06.03.2023

Scientists have done extensive research to show how getting up early affects student learning. It turned out that morning classes in colleges or universities reduce the performance of students.

The researchers were able to estimate class attendance by examining university Wi-Fi login data from more than 20 students. They separately collected data from over 180 students over a 6 week period.

The experts learned that class attendance at 8 am is 10 percent less than class attendance at the end of the day. Students did not wake up on time in almost a third of classes that started at 8 am.

The team then investigated the impact of morning classes on student sleep by studying the online intensity of nearly 40 students.

The scientists say the students went to bed around the same time but woke up earlier to attend morning classes. So, the duration of the night's sleep was shorter only than those nights that preceded the morning classes.

Considering disruption to sleep and attendance, the study found an association between early classes and lower grades.

An analysis of the grades of more than 30 students proved that the number of days per week during which they attended morning classes was negatively correlated with the average score, the researchers said.

The scientists note that universities should consider waiving mandatory early classes. After all, students skip classes more often, sleep less and get a lower GPA.

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, ... >>

Glue - do not tear off 06.10.2006

Microbiologists from the University of Bloomington (USA) have found a bacterium that lives in fast streams and must attach to stones so that it is not carried away by the current.

At the end of the bacterial cell there is a stalk, which, thanks to the heavy-duty glue released at its end, firmly adheres to the stone. By measuring the force required to tear bacteria off glass with a micromanipulator, the scientists found that a one square millimeter adhesive would support a weight of 7 kilograms.

The best adhesives currently in use withstand a gap of 1-8 kilograms. And it is very important that the bacterial adhesive works on wet surfaces. The composition of the glue has not yet been fully deciphered, but it is based on polysaccharides.

It is assumed that it will be possible to establish the production of miracle glue by genetic engineering and use it, for example, in surgery, since polysaccharides in the body are gradually absorbed.
