New LMU research shows how proteins can function reliably even without a stable 3D structure, showing that not only short sequence motifs but also chemical properties are critical. Many proteins are not only composed of stably folded building blocks. They also contain flexible parts known as intrinsically disordered regions (IDRs) that do not form stable three-dimensional structures but play important roles within cells. Such disordered protein domains constitute approximately one-third of all protein structures. Recently, they have attracted significant attention, especially as it has been revealed that they are involved in diverse interactions, can form biomolecular condensates, and are involved…

When vitamin B2 is deficient, tumor cells are susceptible to specific cell death. This was discovered by researchers at the Rudolf Virchow Center at the University of Wurzburg. The human body cannot produce vitamin B2 itself, also known as riboflavin. You need to absorb important substances through your diet. This vitamin is found in dairy products, eggs, meat, and green vegetables. Metabolism converts it into molecules that protect cells from damage such as oxidation. Researchers at the Rudolf Virchow Center (RVZ) at Julius-Maximilians-Universität Würzburg (JMU) have discovered that this function of the vitamin also has a downside. It also protects…

When researchers recommended a customized, scientifically validated exercise program to patients undergoing chemotherapy for cancer, the patients who followed the exercise regimen on a two-week chemotherapy schedule were better able to maintain their step goal, use a resistance band, and stay mentally sharp than those who did not exercise. This national study on exercise and cancer, led by Karen Mustian, PhD, MPH, and Po-Ju Lin, PhD, MPH, RD, of the Wilmot Cancer Institute at the University of Rochester, is important for the following reasons: Up to 75% of cancer patients report cancer-related cognitive impairment, or “chemobrain.” What is chemobrain? Patients…

Astronomers have discovered signs that our sun may have participated in a large-scale movement of similar stars that left the inner regions of the Milky Way galaxy about 4 billion to 6 billion years ago. To investigate this possibility, the researchers used observations from the European Space Agency’s Gaia satellite to compile and analyze a highly accurate catalog of stars. Their results provide new insight into how the Milky Way evolved, particularly the formation of the rotating bar-like structure at the galaxy’s center. On Earth, archeology reconstructs the past by studying ancient artifacts and ruins. In space, scientists use a…

Ten years ago, the Pennsylvania Department of Environmental Protection released a study on radioactivity in the oil and gas industry, motivated by concerns that increasing amounts of toxic fracking waste could pose a risk to the environment and public health. The study concluded, in part, that further research is needed, particularly regarding the impact on the landfills where this waste is disposed of. The agency released a follow-up study Friday specifically looking at landfill leachate, a liquid byproduct that forms when rainwater passes through waste and picks up pollutants along the way. “The important point here is that there is…

Researchers at Nigeria’s Federal University of Technology, Owerri, have identified a promising strategy to reduce pollution from diesel engines without compromising their performance. By analyzing research from around the world, the team looked at a technology known as water-in-diesel emulsion (WiDE). Their findings suggest that adding small amounts of water to diesel fuel has the potential to significantly reduce harmful emissions while maintaining or even improving engine operating efficiency. Diesel engines are reliable and can provide powerful power, which is why they play an important role in transportation, agriculture, and industrial equipment. At the same time, they are also a…

Adolescent rats exposed to chronic stress had reduced signs of depression after taking the herbal supplement ashwagandha, according to a new study published in . psychopharmacology. The study found that the herb not only alleviated behavioral symptoms, but also reduced inflammation and cell damage in the brain, an effect that in some cases exceeded that of the antidepressant sertraline. Although adolescent depression is becoming increasingly common, treatment options remain limited and are often associated with side effects. Scientists have known for years that chronic stress can disrupt brain function by increasing inflammation, damaging nerve cells, and reducing levels of proteins…

Many medical devices must be sterilized for safe use. However, sterilizing pacemakers, catheters, and other devices with steam or heat can compromise their structural integrity. So medical device manufacturers turn to ethylene oxide, a compound that is highly effective at killing microorganisms at low concentrations and allows companies to meet the Food and Drug Administration’s strict sterility standards. As a result, approximately half of the medical devices in Japan are sterilized with ethylene oxide (EtO), which has become the cornerstone of the medical device industry. There’s just one problem. EtO is a toxic gas that has been linked to breast…

Exposure to diets high in fat and sugar during early development causes the brain to overreact to unhealthy foods in adulthood. This combination creates high levels of inflammation and reduces adaptive capacity within the brain’s main memory centers. These molecular changes suggest that the early nutritional environment has long-term effects on cognitive health, according to a recent study published in . nutritional neuroscience. The physical structure of the brain is not determined at birth. It constantly changes and adapts according to life experiences. This feature of the nervous system is known as neuroplasticity. Neuroplasticity allows humans and animals to form…

Genetic mutations that help animals such as yaks and Tibetan antelopes survive at high altitudes may hold the key to repairing neurological damage in conditions such as cerebral palsy and multiple sclerosis (MS). The findings were published March 13 in the journal Cell Press neuronreveals a naturally occurring pathway that promotes regeneration after nerve injury, potentially opening new doors for treating diseases like MS by harnessing molecules already present in the human body. “Evolution is a great gift from nature, providing a variety of genes that help organisms adapt to different environments,” says corresponding author Liang Zhang of Songjiang Hospital,…
