Potato chip breakthrough crunches cancer risk for healthier snack

In what many of us would consider a true public service to one of the world's best food groups, scientists have flicked the switch on a mechanism that causes cold-stored potatoes to produce the carcinogen acrylamide. Growing these genetically tinkered potatoes could eradicate known cancer risks associated with darkened chips, making them much healthier regardless of processing."This discovery represents a significant advancement in our understanding of potato development and its implications for food quality and health,”…

Stubborn liver cancer may have met its match in century-old TB vaccine

A single injection of the 102-year-old tuberculosis vaccine, BCG, has proven effective at triggering an immune response in mice and shrank their liver cancer tumors, according to research by UC Davis Health. The findings suggest that BCG might be an alternative way of treating this notoriously hard-to-treat cancer.As the most common type of liver cancer, hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths worldwide. Despite treatment options that include surgery, radio- and chemotherapy,…

Scientists Reveal How One Type of Lung Cancer Can Transform Into Another

Researchers catch lung cancer transformation in the act: Immunofluorescence image shows small cell lung cancer (purple-pink) spreading throughout the bronchioles (green) of a mouse lung containing residual lung adenocarcinoma tumor cells (blue). Credit: Dr. Eric Gardner, Varmus LabSometimes, lung tumors known as adenocarcinomas develop resistance to treatments that were initially successful, undergoing a transformation into a more aggressive form of cancer called small cell lung cancer (SCLC), which spreads quickly and…

Radioactive ‘fruit sugar’ lights up cancer and inflammation

A radioactive form of fructose, a natural sugar found in fruit, given to mice lit up areas of cancer and inflammation on a diagnostic medical scan. The researchers say the approach makes diseases easier to spot than current techniques and opens the door to new avenues of early detection.A positron emission tomography or PET scan often relies on injecting a small amount of radioactive glucose, called a tracer, into the bloodstream. The scanner creates a picture based on where the glucose is used in the body. Since many…

A New Type of Cancer Drug Shrinks Hard-to-Treat Tumors

In the long and often dispiriting quest to cure cancer, the 1998 approval of the drug Herceptin was a tremendously hopeful moment. This drug for breast cancer was the first to use a tumor-specific protein as a homing beacon to find and kill cancer cells. And it worked. Herceptin has benefited nearly three million people since that time, dramatically increasing the 10-year survival rate—and the cancer-free rate—for what was once one of the worst medical diagnoses. “Honestly, it was sort of earth-shattering,” says…

Scientists Unveil 145 Genes Vital for Genome Health

A groundbreaking study has unveiled key genes linked to DNA damage, offering new perspectives on cancer, neurodegenerative diseases, and potential therapies. This research underscores the significance of maintaining genome stability for health and disease management.Scientists unveil 145 genes vital for genome health, and possible strategies to curb progression of human genomic disorders.More than one hundred key genes linked to DNA damage have been uncovered through systematic screening of nearly 1,000 genetically…

A Solar Eclipse, Cancer Treatments and Robots with AI

Are you planning to watch the total solar eclipse on April 8? Its path travels from Mazatlán, Mexico, through Texas, the Midwest, New England and Newfoundland, and it will be the last total solar eclipse viewable across North America until 2044. Catch it if you can! (I'm going to a relative's house in Ohio and am hoping for clear skies ... but prepared for clouds.) Scientific American contributing editor Rebecca Boyle previews the spectacle and explains why scientists are thrilled with the opportunity it offers to study…

Scientists Tame Shapeless Monster Behind 75% of Cancers

Researchers at UC Riverside have made a groundbreaking discovery in cancer treatment by developing a peptide that can control MYC, a key protein involved in the majority of human cancers. This innovation offers new hope for targeting cancer at a molecular level, paving the way for more effective treatments.Discovery paves the way for more effective treatment.Meet MYC, the shapeless protein responsible for making the majority of human cancer cases worse. UC Riverside researchers have found a way to rein it in, offering…

Alaskapox death brings attention to small animal virus

For nine years, Alaska health officials have been aware of an unusual virus causing rare, relatively mild illnesses in the Fairbanks area.But a recent case in another part of the state — this one resulting in a man's death — has brought new attention to the  Alaskapox virus.Here's some background on the virus.What is Alaskapox?Alaskapox belongs to a family of brick-shaped viruses that can infect animals and humans. These bugs, known as orthopoxviruses, tend to cause lesions, or pox, on the skin. Each has its own…

New Ultrafast Laser Technology Could Improve Cancer Treatment

Research in ultrafast laser technology has unlocked new potential in cancer treatment by achieving electron acceleration to megaelectronvolt levels, promising advancements in FLASH radiotherapy for more effective care, but also necessitating safer laboratory practices due to heightened radiation exposure risks.Canadian research team at INRS makes discovery that could enhance the effectiveness of radiation therapy in oncology.Ultrafast laser technology consistently delivers unexpected advancements. At first look, studies…
