Cancer cells survive by hiding from the immune system’s surveillance. A KAIST research team has developed a new anticancer platform that makes cancer cells send out their own danger signals—prompting immune cells to attack—while simultaneously delivering gene therapy. The approach is expected to offer a new treatment strategy that combines cancer immunotherapy and gene therapy in a single nanoparticle.
Immunogenic cell death (ICD) is a process in which dying cancer cells send danger signals to nearby immune cells, prompting them to attack. A polypeptide is a polymer made of a long chain of amino acids.
A team led by Professor Yeu-Chun Kim from the KAIST Department of Chemical and Biomolecular Engineering developed a “helical polypeptide nanoparticle” platform that induces severe stress inside cancer cells to trigger immunogenic cell death while also delivering a range of gene therapeutics into the cells. The findings are published in the journal Biomaterials.
Researchers imaged mouse brains during natural sleep, tracking blood flow and energy metabolites. REM sleep increased blood volume and pyruvate but reduced neuronal ATP, revealing a distinct metabolic state that may support memory-related processing.
Glioblastoma is a malignant brain tumor and is among the most aggressive cancers in humans. Despite multimodal therapy with surgery, radiation and chemotherapy, there is still no cure. A major reason is the tumor’s invasive behavior: Glioblastoma cells migrate far beyond the visible tumor into healthy brain tissue. These infiltrating cells cannot be completely removed and seed tumor recurrence—often within just a few months.
“To understand why glioblastoma keeps coming back, we need to look closely at the tumor cells that remain hidden in the brain after surgery,” says Dr. Matthias Schneider, deputy director of the Department of Neurosurgery at the UKB and head of the Brain Tumor Translational Research Group at the UKB and the University of Bonn. “Core2Edge allows us to study these infiltrative tumor cells in a model based entirely on human tissue, closely mirroring what we see in patients.”
The study is published in the journal Nature Protocols.
On Sunday, July 19, 2026, at 1 p.m. U.S. Pacific Time, watch the third compilation stream, consisting of three additional presentations from the May 3, 2026, sessions at the University of California, Berkeley Conference on Aging and Longevity (BerkeleyCAL), hosted by Professor Steven A. Garan, Director of Bioinformatics at the Center for Research and Education on Aging.
These presentations delve into cutting-edge science, including actual human trials on rejuvenation, efforts to improve human longevity through genetic screening, and models of senescence at the cellular level. They are delivered by renowned longevity researchers Gregory Fahy, Wei-Wu He, and Andreas Stahl. The presentations include question-and-answer sessions, including questions posed by U.S. Transhumanist Party Chairman Gennady Stolyarov II to Andreas Stahl.
Dr. Greg Fahy of Intervene Immune presents evidence that thymic involution—the age-related decline of the thymus gland—is a primary driver of immune failure and various age-related diseases, including cancer and cardiovascular issues. To address this, he details the multiple TRIIM clinical trials in small cohorts of human patients, which successfully demonstrate that a combination of growth hormone, DHEA, and metformin can safely regenerate functional thymic tissue and rejuvenate the immune system.
Dr. Wei-Wu He of Human Longevity, Inc., emphasizes the critical importance of whole-genome sequencing for personalized longevity and healthcare, noting that genetics account for approximately 50–55% of an individual’s healthspan and lifespan. Reflecting on the legacy of Human Longevity, Inc. founder Dr. J. Craig Venter (1946−2026), Dr. He’s presentation advocates for utilizing genomic data alongside AI and advanced clinical diagnostics to shift from reactive sick care to proactive, data-driven prevention. Dr. He highlights new, accessible initiatives to bring comprehensive genomic analysis and proteomic testing to the public to help individuals identify and manage their unique health risks.
Dr. Andreas Stahl of UC Berkeley presents a microphysiological \.
Ancient DNA can be a powerful tool for helping us reconstruct the long-dead past. Most surviving genetic material comes from the bones and teeth of animals that lived in cold environments, where freezing temperatures help prevent decay. While hotter climates are seen as hostile to preservation, researchers have recently extracted DNA from a tooth found in South Africa that may date to around 50,000 years ago—the oldest yet retrieved from sub-Saharan Africa.
Despite many fossil-rich sites across the continent, such as South Africa’s coastal caves, few ancient DNA projects have been carried out because of the expectation of poor preservation. But that didn’t stop an international team of researchers who wanted to see whether it was possible to extract viable DNA from ancient skeletons across different time periods and sites in South Africa.
The results of their work are published in the journal Quaternary Science Reviews.
Differentiating radiation necrosis (RN) from tumor recurrence (TR) in previously irradiated brain metastases (BM) remains a challenge. Imaging techniques lack sufficient diagnostic reliability, while therapeutic implications differ between both entities. This study aims to evaluate the diagnostic, therapeutic, and prognostic value of surgery in patients with progressive irradiated BM.
We studied patients who underwent surgical resection for progressive BM after prior irradiation. Histopathological diagnosis was classified as pure RN or TR. Clinical, radiological, surgical, and survival outcomes were analyzed.
In 73 lesions, histopathology demonstrated TR in 68.5% of lesions. Among TR, 84.0% showed mixed pathological features combining viable tumor cells and radionecrotic patterns. Patients initially treated by irradiation alone were significantly more likely to present TR, whereas surgery followed by postoperative irradiation was significantly associated with RN. Median interval between radiation and surgery was significantly longer in the RN group and breast cancer seemed related to RN. Postoperative clinical improvement occurred in 80.4% of symptomatic patients and corticosteroid discontinuation within one month occurred in 72.3% of patients, without significant difference between RN and TR. Median overall survival was longer in patients with RN (39 vs. 19 months, p = 0.025).

Scientists at Virginia Tech’s Fralin Biomedical Research Institute at VTC have discovered how an experimental therapy can help brain cells overcome the effects of a disease-causing genetic deletion. Instead of repairing the deletion and its immediate consequences, the therapy redirects brain development by helping at-risk neurons grow and connect more normally.
The findings, published in Disease Models & Mechanisms, suggest that some genetic brain disorders may be treated by targeting the cellular mechanisms disrupted by a genetic change rather than repairing the genetic change itself.
Wearable health monitors have grown increasingly capable, but most are still limited by the fact that tracking different types of body signals requires separate sensors, each with its own circuitry and patch of skin. That leads to bulkier devices, higher power consumption and greater discomfort for anyone who needs round-the-clock monitoring.
A research team led by Assistant Professor Liu Yuxin from the Department of Biomedical Engineering at the College of Design and Engineering, National University of Singapore (NUS CDE), has developed a cross-modal skin sensor that overcomes this constraint.
Named X-Sig, the device fuses the body’s electrical impulses, such as heart rhythms and muscle signals, with its mechanical signals, such as pulse pressure waves and the forces generated by muscle contractions, into a single composite waveform transmitted through one channel.
