New type of DNA damage found in our cells’ powerhouses

A new type of DNA damage, glutathionylated DNA adducts, accumulates at high levels in mitochondrial DNA, affecting energy production and stress response. The discovery sheds light on how cells sense and respond to stress, with potential implications for diseases like cancer and diabetes.

The ins and outs of quinone carbon capture

Quinone-based carbon capture systems have been found to trap and release CO2 from the atmosphere through two distinct mechanisms. The study provides critical insights into the interplay of electrochemistry in these safer systems.

Studying how skin cancer starts

Scientists at Case Western Reserve University have discovered how quickly certain pre-cancerous lesions can form on the DNA of our skin when exposed to sunlight, a finding that could lead to more effective prevention methods. The research reveals that these mutations can form in as little as three picoseconds after exposure to UV light.

Fluke 87V Industrial Digital Multimeter

Fluke 87V Industrial Digital Multimeter is a trusted meter for precise measurements during instrument integration, repairs, and field diagnostics.

Cracking colibactin's code

Researchers studied how colibactin damages DNA and created a novel technique to identify DNA adducts. They isolated and characterized the products of the reaction with DNA, revealing a cyclopropane ring structure that forms the colibactin warhead.

Damaged DNA amplified

Researchers at ETH Zurich have developed a method to amplify gene samples containing damaged DNA adducts, which are common in cancer. This breakthrough could enable the analysis of molecular mechanisms involved in cancer initiation and risk factors.

Creality K1 Max 3D Printer

Creality K1 Max 3D Printer rapidly prototypes brackets, adapters, and fixtures for instruments and classroom demonstrations at large build volume.

A step toward a saliva test for cancer

A new saliva test can measure the levels of five key DNA adducts, which form when potentially cancer-causing substances bind to DNA. The test is convenient and non-invasive, making it a potential tool for health promotion and disease prevention.

Arylamine exposure related to bladder cancer risk

A case-control study of 300 bladder cancer patients and 300 control subjects found higher levels of arylamine-hemoglobin adducts in cancer patients than in control subjects. The findings suggest exposure to arylamines is a causal factor for most cases of bladder cancer in humans, with potential non-smoking-related sources identified.

Chopping And Cooking Affect Garlic's Anti-Cancer Activity

A study by Penn State researchers found that microwaving or roasting garlic can destroy its anti-cancer activity, unless the herb is chopped or crushed first. However, a 10-minute standing period allows an enzyme to react with chemicals, producing allyl sulfur compounds that retain anti-cancer properties.
