Every year in the United States, more than 60,000 people get a leukemia diagnosis and about 23,000 people die annually from it (Leukemia and Lymphoma Society). Leukemia is the sixth-leading cause of cancer deaths among men. The current and traditional treatments that medicine is currently using are often unsatisfactory and offer limited hope. The outcomes of these cures clearly highlight the need for new advanced therapies for leukemia like anticancer peptides. Anticancer peptides are wonders in the world of cancer research. These types of peptides are special proteins that have the power to target and fight against cancer cells; they come from three different types of peptides: naturally occurring or derived from a known protein, cell penetrating peptides and tumor targeting peptides. In this article we will discuss how anticancer peptides work and how they impact leukemia treatments. These types of treatments are very promising, many new therapies are currently being used to treat cancer. Among these new methods, chemotherapy based on peptides has been of great interest due to the unique advantages of peptides, such as a low molecular weight, the ability to specifically target tumor cells, and low toxicity in normal tissues.

Among evolutionary problems, eukaryogenesis is one of the most interesting, with many published theories proposing different evolutionary transition states in an effort to explain how it may have occurred in a way that aligns with current empirical evidence 1. Among the most detailed and well known theories is the Hydrogen Hypothesis, first published in 1998, updated in 2015 and in the meantime popularised in the public conscience in no small part by Nick Lane’s 2005 book Power, Sex, Suicide: Mitochondria and the meaning of life. While the Hydrogen Hypothesis played a significant part in popularising symbiogenetic theories for eukaryogenesis, it is not the only such theory out there. Another equally detailed theory is the Syntrophy Hypothesis, also published in 1998. And while the 1998 Syntrophy Hypothesis arguably less convincing than the 2015 H2 Hypothesis 1, its 2020 revision does warrant a reevaluation of its strength vis a vis the H2 Hypothesis

The relationship between happiness and economic indicators has long been a topic of debate and discussion among economists. Many researchers have been interested in the topic, specifically the effects that inflation and unemployment have on happiness. In this article, I study the influence that inflation and unemployment have on happiness by using the largest most up-to-date possible dataset. The data used for analysis are inflation rate, unemployment rate and happiness index from over 100 countries. I calculate correlation coefficients, run trendline regressions and draw scatter plot diagrams to mathematically analyze the data. The trendline regressions show that as inflation and unemployment increases, the overall happiness in a country tends to decrease. In fact, the calculation of the correlation coefficients shows that unemployment has a greater impact on happiness than inflation does (-0.19 vs -0.17). According to this study, inflation and unemployment inversely affect happiness. This study solidifies the belief that a better economy leads to higher social well-being, or happiness

The extracellular matrix is a vital component of a cellular system. It is responsible for several metabolic processes within cells and its properties can have major effects on cellular activity. Recent research has begun to understand the role of physical interactions between the matrix and the cell on cellular growth and repair. In this work, we review the role of the stiffness of the extracellular matrix in determining cellular activity. We first review the effect on stem cell differentiation through the influence of cytoskeletal feedback loops and induced traction stresses. We then discuss the effects of metabolic reprogramming in tumor progression via molecular upregulation of YAP/TAZ and genetic expression. Finally, we highlight the effects of the stiffness gradient dictated by durotaxis and induced hypoxia on the rate of tumor progression. We hope this review sheds light on the major impact that the extracellular matrix has on various biological activities.

Air pollution and its adverse effects on human health are critical environmental concerns globally. This study investigates the complex relationships between air pollution, CO2 emissions, and crude death rates in Kazakhstan, a country facing significant environmental challenges due to industrialization and economic growth.

National-level data spanning 1990 to 2020 were obtained from the World Bank database and analyzed to explore temporal trends in death rates, CO2 emissions, and air pollution metrics. The results reveal a sustained rise in crude death rates during the early 1990s, followed by a notable decline until 2014, indicating potential advancements in healthcare and living conditions.

However, subsequent years experienced a slower decline, with an exceptional spike in 2020, possibly associated with the COVID-19 pandemic. CO2 emissions exhibited a downward trend with fluctuations, reflecting economic activities' dynamics. A multiple linear regression analysis found that PM2.5 air pollution exposure and mean annual exposure emerged as significant predictors of crude deaths while CO2 emissions had no significant predicting effect.

As Kazakhstan continues to invest in environmental and health quality, attention to PM2.5 exposure should be monitored.

Climate change manifests through increasing global temperatures and disrupted weather patterns that threaten the natural equilibrium of Earth's ecosystems, posing significant risks to both human and non-human life forms. The primary driver of this phenomenon is the accumulation of greenhouse gases, particularly carbon dioxide (CO2), released through anthropogenic activities such as fossil fuel combustion and deforestation. These greenhouse gases create a selective barrier in Earth's atmosphere that allows incoming solar radiation to pass through while preventing infrared radiation from escaping, resulting in a warming effect on the planet's surface. This mechanism, known as the greenhouse effect, continues to intensify as human activities increase atmospheric greenhouse gas concentrations, leading to accelerated global climate change.
