  • Dormant pigment cells found in vitiligo patches may offer treatment target
    on July 23, 2026 at 7:00 pm

    Vitiligo is an autoimmune disease in which the body’s immune system attacks and destroys melanocytes, the cells that produce the skin pigment melanin. Once the melanocytes are gone, the skin turns white, leading to the characteristic skin patches of the disease. However, the standard model of vitiligo doesn’t explain some of its unusual features. Some vitiligo lesions repigment, and treatments sometimes restore pigmentation even in areas that lack melanocytes, suggesting that the melanocytes may not be fully destroyed.

    You may have heard that colorectal cancer is increasingly affecting young adults. However, it is not the only gastrointestinal (GI) cancer that doctors are diagnosing in patients below the age of 50, explains Christina Wu, M.D., an oncologist at Mayo Clinic Comprehensive Cancer Center in Arizona.

    A research team led by Professor Jae Youn Hwang of DGIST’s Department of Electrical Engineering and Computer Science, in collaboration with a team led by Professors Euiheon Chung and Hyuk Sang Kwon of GIST’s Department of Biomedical Science and Engineering, has developed an “AI-based thickness-optimized acoustic hologram (TOAH)” technology that directly optimizes the thickness of a 3D-printed lens to simultaneously and precisely stimulate multiple regions of the brain.

  • Chemotherapy leaves detectable DNA fingerprints in childhood tumors within 18 months
    on July 23, 2026 at 6:40 pm

    Nearly half of childhood tumors treated with common types of chemotherapy showed detectable DNA changes linked to treatment within 18 months, according to a new international study led by The Hospital for Sick Children (SickKids). Researchers say these changes could eventually help clinicians spot treatment resistance earlier, before cancer returns or spreads, opening the door to more precise use of chemotherapy.

  • Two new therapies and rapid tests could reshape drug-resistant gonorrhea care
    on July 23, 2026 at 6:20 pm

    Drug-resistant Neisseria gonorrhoeae (the bacterium that causes gonorrhea) has become one of the most urgent antimicrobial-resistant threats to public health worldwide. Clinicians expect to be confronted by rising rates of treatment failure in the years to come.
