Designer proteins unlock near-infrared and SWIR glow for deeper tissue imaging
Researchers at the National Center for Tumor Diseases (NCT/UCC) in Dresden, including Oliver Bruns and Dr. Bernardo Arús, are participating in an international study that has, for the first time, developed novel proteins for near-infrared (NIR) and short-wave infrared imaging (SW
Researchers develop a new prodrug and localized drug delivery platform for selective treat
Researchers develop a new prodrug and localized drug delivery platform for selective treat
A new collaborative study reports the discovery and application of a novel therapeutic strategy to selectively target EGFR and other kinases with controlled release in tumor microenvironments to improve therapeutic efficacy, with promising results. The research is published in Bi
FDA-approved drug may finally help immunotherapy defeat rare liver cancer
Researchers found that a rare liver cancer evades immunotherapy by luring immune T cells away from the tumor and trapping them in nearby fibrous tissue. An FDA-approved drug called AMD3100 freed those T cells to attack the cancer, significantly improving the effectiveness of immu

Engineers discover 'unexpected motion' in drug-delivery robots
One day, tiny swimming robots may travel through the human body to deliver drugs. The medication would target only areas of need—chemotherapy drugs for a tumor, for example—avoiding healthy tissue and minimizing side effects. A research team led by Ebru Demir, an assistant profes
Turning up the heat on cancer: Manganese ferrite nanoparticles outperform rivals
Scientists have long known that heat can be used to help fight cancer. But heating tumors and cancer cells is trickier than it sounds. Apply too much heat and patients could get hurt; apply too little or target the wrong location and the therapy will not be effective.
Tiny silica particles wiped out aggressive prostate cancer in mice
Tiny silica particles wiped out aggressive prostate cancer in mice
Tiny silica nanoparticles engineered to seek out prostate cancer caused tumor cells to self-destruct and supercharged the immune system in preclinical mouse studies. Combined with immunotherapy, the treatment produced complete remissions in multiple mice, raising hopes for a powe
A hidden immune backup system could supercharge mRNA cancer vaccines
A hidden immune backup system could supercharge mRNA cancer vaccines
Researchers found that mRNA cancer vaccines can recruit an unexpected immune cell to launch powerful tumor-fighting responses, overturning a long-held assumption about how the vaccines work. The discovery could lead to more effective cancer vaccines and help scientists tailor tre
This frog bacterium wiped out cancer tumors in mice with a single dose
This frog bacterium wiped out cancer tumors in mice with a single dose
A naturally occurring bacterium from amphibian intestines completely eliminated colorectal tumors in mice with a single treatment by both attacking cancer cells and activating the immune system. The findings point to a promising new type of cancer therapy that could one day work

This week, researchers reported finding nanoplastics in Antarctic soils for the first time, suggesting they were delivered via long-range atmospheric transport. A study associates the use of hormonal birth control with the risk of brain tumors. And researchers developed a new dru
Common blood pressure drug could make cancer therapy far more powerful
Common blood pressure drug could make cancer therapy far more powerful
Researchers found that the common blood pressure drug telmisartan can significantly improve the performance of the cancer drug olaparib, potentially expanding its benefits beyond patients with BRCA-related tumors. The combination is already being tested in human clinical trials a

Sam Neill venceu o linfoma com terapia CAR-T — mas não foi o câncer que o levou
O ator de 'Jurassic Park' havia entrado em remissão após tratamento inovador com células modificadas. Sua morte por causas não relacionadas ao câncer reacende o debate sobre saúde integral.
Ozempic contra o câncer? O que a ciência diz (e o que as manchetes exageram)
Ozempic contra o câncer? O que a ciência diz (e o que as manchetes exageram)
Os medicamentos GLP-1 estão no centro de um debate acalorado após estudos apresentados no maior congresso de oncologia do mundo. Entenda o que realmente sabemos — e o que ainda é especulação.
