First cancer vaccine appears in England

The first cancer vaccine has emerged in England. Currently, it is undergoing the third stage of trials on patients. It should be noted that the vaccine does not eliminate tumors. For now, scientists are adapting each injection to suit the patient - the vaccine activates their immune system to destroy cancer cells. As a result, the recurrence rate is significantly lowered. If the trials are successful, a new era of fighting cancer will begin.

Physical Activity and Mental Health: Lowering the Risk of Depression

Scientists have conducted an analysis of several studies, which showed that moderate physical activity, such as gardening and landscaping, golf, and walking, is associated with a lower risk of depression. They examined data from over four million people and the correlation between physical activity and episodes of depression, as well as other mental disorders. It was found that low and moderate-intensity physical exercises on average reduce the risk of depression by 23%, anxiety by 26%, and psychosis or schizophrenia by 27%.

Vaccination: the path to health

Vaccination has saved 154 million lives over 50 years, according to WHO experts. The most significant impact has been from measles vaccines, which account for 94 million lives saved (around 60% of the total number). However, in 2022, 33 million children did not receive full vaccination against this disease. As a result of polio immunization, 20 million people on Earth, who would otherwise be paralyzed, can walk. Full eradication of the disease is now considered an achievable goal. Additional prospects for vaccination success include vaccines against papillomavirus infection, malaria, COVID-19, as well as vaccines against cholera and Ebola viruses, used to contain outbreaks.

Weekend Sleep Helps Reduce Anxiety and Depression Risk, Scientists Say

Scientists have found that people who catch up on sleep over the weekend experience reduced anxiety and depression risk. The study suggests that compensating for the lack of sleep during weekdays can help alleviate depressive symptoms. To decrease or completely eliminate depressive symptoms, it is necessary to sleep for at least a few extra hours on Saturday and Sunday: one additional hour of sleep reduces symptoms by 38%, while two additional hours decrease symptoms by 46%. Furthermore, individuals who typically sleep for 5-6 hours notice the most significant changes in their well-being.

Chinese Scientists Develop AI-Based Test to Detect Cancer from Dried Blood

In China, researchers have created an AI-based test that can detect cancer from dried blood. Preliminary trials have shown that the tool is capable of detecting pancreatic, gastric, and colorectal cancer, providing results in just a few minutes. Scientists believe that implementing screening in low- and middle-income countries can reduce the proportion of undiagnosed cancer cases among the aging population. The main components of this test are much cheaper than traditional methods.

Improved Patient Outcomes with Female Doctors

Forecast for patients is better with female doctors. Scientists analyzed data from over 458,000 women and over 318,000 men hospitalized over several years to understand the impact of a doctor's gender on treatment. They examined the number of patients who died within 30 days of hospital admission and the number of readmissions. It turned out that female doctors achieved better results. The difference was even more noticeable when the patient was also a woman, especially when it came to serious illnesses.

Artificial intelligence reduces drug consumption

Artificial intelligence has helped reduce drug consumption. Researchers have found that AI-based chatbots can be used to control and limit medication intake. In experiments, ChatGPT analyzed the composition of drugs and discontinued ineffective ones. The AI tool was cautious in decision-making, often preserving the existing treatment regimen and frequently canceling opioid prescriptions compared to other types of medications.

Bacteria on the ISS have mutated and become drug-resistant

Microbiologists have studied the DNA of the bacterial species Enterobacter bugandensis, which was found on board the International Space Station in 2018. This type of microbe is not directly harmful to humans, but it could pose a potential threat. It turns out that the microorganisms have accumulated various mutations, making them functionally distinct from their earthly counterparts and resistant to known antibiotics.

Chemicals Linked to Cancer Found in Band-Aids

Chemicals that can cause cancer have been found in band-aids. Researchers have tested popular brands of band-aids in the laboratory and found that 65% of them contain organic fluorine, an indicator of harmful chemicals. These chemicals are sometimes used in adhesives and in the production of stickers, as well as providing waterproofing. In band-aids, these substances have been found in the adhesive part. Previous laboratory studies have shown that the exposure of these chemicals to the skin poses the same health risk as if they were ingested through food or water.

Artificial intelligence identifies the brain region where psychosis occurs

Artificial intelligence has determined which area of the brain psychosis arises from. The neural network detected differences in brain activity between patients with and without psychosis. In control groups, the model accurately identified the presence of psychosis through brain scans with an accuracy ranging from 84% to 90%. Scientists plan to target these key brain regions using existing treatment methods, such as brain stimulation, to observe if they can prevent or delay psychosis.

Fast Food: A Detriment to Memory

Fast food permanently impairs memory. American researchers conducted experiments on rats and found that a large amount of fatty and sugary food in the diet permanently impairs the ability to remember information. The rats were offered to explore new objects in different places. After a few days, the animals were placed in the same environment as before, but with the addition of a new item. The test subjects who consumed unhealthy food could not recall what and where they had already seen, while the animals from the control group recognized familiar objects. Specialists believe that such dietary behavior during adolescence in humans can lead to similar consequences, which will persist even in adulthood, even when switching to a healthy diet.

The Impact of Sleep Deprivation on Health

Lack of sleep can cause as much damage to the body as alcoholism. Regular sleep problems can lead to fatty liver disease, which can eventually result in cirrhosis or even liver cancer. All of these are symptoms of severe alcoholism. The only solution is to get at least 7-8 hours of sleep per day. Doctors even refer to this as a new 'silent epidemic'. Many suffer from sleep deprivation, but no one is dying en masse.

The Negative Effects of Noise-Canceling Headphones on the Brain

A study has shown that noise-canceling headphones are very bad for the brain. Sounds are processed worse, and at some point, audio information may stop being perceived altogether. Noise-canceling technology blocks out external sounds, causing the brain to adapt to such an environment and potentially start ignoring any external noises. Ultimately, there is a possibility of complete hearing loss.

The Effects of Insomnia on Skin Health

Simba Company has modeled people suffering from insomnia. If you sleep less than 7 hours, you will develop more wrinkles, dryness, and dark circles under your eyes, similar to a panda. According to the company, this happens because cells do not have enough time to recover.

Scientists Use Smart Rings to Measure Stress Levels During Sleep

Scientists have developed a method to determine stress levels during sleep using smart rings. During this time, the human body can provide a significant number of specific signals. Smart rings that collect pulse data have helped prove that 8-9 hours of sleep are necessary for well-being. Each additional hour reduces the likelihood of stress by 38%.

Are Asian Soups Addictive? Expert Opinions

Asian soups are said to be addictive, according to dietitians. Doctors believe that the combination of spicy, sour, and sweet flavors is the reason behind this. However, dietitians have no objections to Asian soups. Doctors consider these dishes to be low in calories and sufficiently beneficial for the body.

World Ranking of Largest Buttocks

Researchers have published a ranking of the largest buttocks from around the world: 1. South Africa (106 cm) 2. Argentina (104 cm) 3. Sweden (103.9 cm) 4. Greece (103.5 cm) 5. Germany (103.1 cm) 6. Italy (102.9 cm) 7. Australia (102.87 cm) 8. Netherlands (102.5 cm) 9. Canada (102.4 cm) 10. France (102.2 cm) The smallest hip circumference is in India - only 91.7 centimeters.

Some US Companies Want to Pay Employees with Mushrooms, MDMA, and Ketamine

In the United States, many companies want to compensate their employees with mushrooms, MDMA, and ketamine. Some may receive permission in the coming months. American doctors believe that these drugs can effectively treat depression and PTSD. Moreover, they will not have as strong an impact on employees' lives as antidepressants.

Research by Japanese scientists

Japanese scientists at Tokyo University have successfully combined lab-grown models of the human brain using long neuronal projections for the first time, leading to synchronization of neural activity. As the human brain functions as a unified entity due to functional neural connections between different regions, which are formed through axons - the long projections of neurons from one area to another, the ability to grow them will enhance research aimed at understanding various neurological and psychiatric conditions.

Evening workouts proven to be more effective

Medics have proven that evening workouts are more effective than any other time of day. The study focused on individuals diagnosed with obesity, aiming to determine whether exercises at a specific time can neutralize certain negative effects. The observation was conducted over eight years, during which doctors recorded cases of death from any cause, as well as new diagnoses of cardiovascular and other diseases. The results showed that individuals who performed various types of workouts in the evening had greater health benefits compared to sedentary individuals.
