What marsupials are almost unaffected by any snake venom?

Venomous snakes form an essential part of the diet of many opossum species, which have little to no effect on the venom. The scientists isolated the protein responsible for this in the blood of opossums, calling it the lethal toxin neutralizing factor, or LTNF. Experiments were conducted with mice that were injected with this protein, and then with lethal doses of various poisons. LTNF has successfully neutralized snake venoms, even from Asian and Australian snakes, which North American opossums never encounter. LTNF also successfully resisted scorpion venom, ricin and botulinum toxin - all this gives hope for the creation of a universal antidote for humans based on this substance of opossums.

How soon did American President Woodrow Wilson break his main campaign promise?

In November 1916, at the height of the First World War, Woodrow Wilson was elected by a wide margin to a second term.

His supporters campaigned under the slogan "With Wilson we are out of the war", which allowed them to secure votes, especially women. However, in April 1917, the United States declared war on Germany.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. 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, ... >>

Depression reduces the effectiveness of chemotherapy 23.12.2016

The patient's depressive state significantly reduces the effectiveness of chemotherapy treatment - the mechanism of this phenomenon was described by researchers from the Chinese University of Zhengzhou.

Patients with depression had lower blood levels of a protein called brain-derived neurotrophic factor (BDNF), which worsened their response to the drug and contributed to more frequent side effects from treatment.

The researchers worked with 186 patients who had recently been diagnosed with cancer and were receiving chemotherapy. The day before the start of treatment, scientists determined their emotional state and severity of depression. Other patient information was also collected to look for possible patterns.

Predictably, the highest levels of depression are diagnosed in people whose cancer has spread to multiple organs. Such patients responded worse to chemotherapy and more often showed various side effects from the treatment. The content of the BDNF protein in the blood of patients directly correlated with the number of cells that died from chemotherapy.

The authors of the work note that doctors should pay more attention to the emotional state of the patient. However, more research is needed to show exactly how antidepressants affect the increase in the level of the BDNF protein in the blood, and hence the effectiveness of treatment. Based on these data, it will be possible to develop new treatment protocols for cancer patients, taking into account their mental state.
