New advanced imaging technology enables detailed disease mapping in tissue samples
Researchers from Aarhus University—in a major international collaboration—have developed a groundbreaking method that can provide more information from the tissue samples doctors take from patients every day.
The new technique, called Pathology-oriented multiPlexing or PathoPlex, can look under a microscope at over 100 different proteins in the same small piece of tissue—instead of just 1–2 at a time, as is done now.
The technology, which has just been published in the journal Nature, combines advanced image processing with machine learning to map complex disease processes in detail.
Stevia leaf extract has potential as anticancer treatment, researchers find
Stevia may provide more benefits than as a zero-calorie sugar substitute. When fermented with bacteria isolated from banana leaves, stevia extract kills off pancreatic cancer cells but doesn’t harm healthy kidney cells, according to a research team at Hiroshima University.
The researchers published their findings on April 28 in the International Journal of Molecular Sciences.
“Globally, the incidence and mortality rates of pancreatic cancer continue to rise, with a five-year survival rate of less than 10%,” said co-author Narandalai Danshiitsoodol, associate professor in Department of Probiotic Science for Preventive Medicine, Graduate School of Biomedical and Health Sciences.
Ancient Killer Is Rapidly Becoming Resistant to Antibiotics, Warns Study
In spite of having plagued humans for millennia, t yphoid fever is rarely considered in developed countries today. But this ancient threat is still very much a danger in our modern world.
According to research published in 2022, the bacterium that causes typhoid fever is evolving extensive drug resistance, and is rapidly replacing strains that aren’t resistant.
Currently, antibiotics are the only way to effectively treat typhoid, which is caused by the bacterium Salmonella enterica serovar Typhi (S Typhi). Yet over the past three decades, the bacterium’s resistance to oral antibiotics has been growing and spreading.
Tsinghua University holds Tsinghua AI Agent Hospital Inauguration and 2025 Tsinghua Medicine Townhall Meeting-Tsinghua University
On the morning of April 26, Tsinghua University held an inauguration ceremony for Tsinghua AI Agent Hospital and the 2025 Tsinghua Medicine Townhall Meeting at the Main Building Reception Hall. Tsinghua President Li Luming and Vice President Wang Hongwei attended the event.
President Li Luming reviewed the progress of Tsinghua University’s medical programs over the past year, emphasizing the University’s strong commitment to the development of medical disciplines. He highlighted Tsinghua’s strength in fundamental research in Artificial intelligence, which has already led to a series of high-level innovations at the intersection of AI and medicine. The establishment of the Tsinghua AI Agent Hospital represents a new initiative by Tsinghua to leverage its strengths in science and engineering to empower the advancement of medicine.
President Li encouraged Tsinghua Medicine to remain committed to fostering virtue and talent, cultivating a new generation of medical innovators with both a strong medical foundation and AI literacy. He also called for deeper integration across disciplines, particularly between engineering and medicine, as well as closer ties between clinical practice and technology. Finally, he urged Tsinghua Medicine to align its work with cutting-edge global trends and national strategic needs, driving medical advancement and contributing to the protection of public health.
A tiny implant just helped paralyzed rats walk again—is human recovery next?
A groundbreaking study from the University of Auckland and Chalmers University of Technology is offering new hope for spinal cord injury patients. Researchers have developed an ultra-thin implant that delivers gentle electric currents directly to the injured spinal cord. This device mimics natural developmental signals to stimulate nerve healing, and in animal trials, it restored movement and touch sensation in rats—without causing inflammation or damage.
