Tumor electrophysiological abnormalities, characterized by membrane potential dysregulation, ion channel network remodeling, and microenvironmental signaling interactions, are critical drivers of malignancy. A central feature is the depolarization of the transmembrane resting potential (Vm), a hallmark of tumor cells that promotes proliferation, maintains cancer stem cell (CSCs) undifferentiated states, and facilitates metastatic remodeling. These abnormalities extend beyond the plasma membrane: CSCs exhibit mitochondrial membrane potential hyperpolarization with a pronounced pH gradient between the matrix ...

A new study warns that contamination from laboratory reagents could be misleading scientists worldwide in their hunt for emerging infectious diseases. Researchers found that silica membranes—commonly used in nucleic acid extraction kits—can harbor parvoviruses and other viral contaminants, creating false virus–host associations in metagenomic sequencing (mNGS) data. These misleading links can affect clinical diagnostics, zoonotic surveillance, and public health responses. In mNGS analyses of patient samples from multiple regions in China, the team detected dozens ...

Medical databases are undergoing rapid expansion, with the number of observed values and variable types continuously increasing, resulting in increasingly rich data content. This growth leads to a significant expansion in the size of individual data files, encompassing both an increase in the number of rows (length) and the number of columns (width). For instance, the chartevents file in the MIMIC 3.0 database boasts hundreds of millions of records, and the numeric file in the Amsterdam Critical Care Database version 1.0.2 is similarly large. In contrast, ...

A new study maps the planetary boundary of “functional biosphere integrity” in spatial detail and over centuries. It finds that 60 percent of global land areas are now already outside the locally defined safe zone, and 38 percent are even in the high-risk zone. The study was led by the Potsdam Institute for Climate Impact Research (PIK) together with BOKU University in Vienna and published in the renowned journal One Earth.

Kyoto, Japan -- As space programs evolve and we continue to mistreat our own planet, human dreams of space tourism and planetary colonization seem increasingly common. However, features of spaceflight such as gravitational changes and circadian rhythm disruption -- not to mention radiation -- take a toll on the body, including muscle wasting and decreased bone density. These may even affect our ability to produce healthy offspring. Studying the impact of spaceflight on germ cells -- egg and sperm precursor cells -- is particularly important because they ...

It has long been understood that experiencing two senses simultaneously, like seeing and hearing, can lead to improved responses relative to those seen when only one sensory input is experienced by itself. For example, a potential prey that gets visual and auditory clues that it is about to be attacked by a snake in the grass has a better chance of survival. Precisely how multiple senses are integrated or work together in the brain has been an area of fascination for neuroscientists for decades. New research ...

A Medical University of South Carolina team reports in Frontiers in Immunology that it has engineered a new type of genetically modified immune cell that can precisely target and neutralize antibody-producing cells complicit in organ rejection. Similar strategies have been used to stimulate the immune system against certain cancers, but Ferreira’s team is the first to show its utility in tamping down immune responses that can lead to organ rejection. More than 50,000 organ transplants take place each year in the U.S. While often lifesaving, these procedures depend on a precise match between donor and recipient genes to avoid rejection. When the immune system detects foreign ...

As the world’s largest wheat producer, China’s annual wheat output reaches 136 million tons, and the stability of its production is directly related to global food security. However, in recent years, China’s wheat imports have continued to rise, reaching 9.96 million tons in 2022. Meanwhile, environmental problems caused by excessive fertilizer application have become increasingly prominent. How to ensure output while reducing resource consumption and environmental costs has become a core issue for sustainable agricultural development. Recently, ...

As a staple food for more than half of the global population, the high and stable yield of rice is directly related to food security. As the world’s largest rice producer, China has increased rice yield per unit through intensive fertilization and flood irrigation, but this model has also brought problems such as soil degradation, water pollution, and greenhouse gas emissions. How to ensure food supply while breaking through resource and environmental constraints? Xusheng Meng and colleagues from Nanjing Agricultural University proposed a green, high-yield, and high-efficiency rice technology system in a review study, providing a solution to this problem. The ...

The North China Plain is an important “granary” in China, with its winter wheat and summer maize planting areas accounting for 73.6% and 30.6% of the national total for wheat and maize respectively. However, its agricultural production has long been trapped in the dilemma of “high input, low efficiency”—fertilizer usage has increased more than 4 times compared with 40 years ago, while grain output has only risen by 1.2 times. Problems such as over-exploitation of water resources and soil degradation have also become increasingly prominent. How to balance ...
