Researchers have genetically modified Salmonella bacteria to reduce virulence and increase safety while retaining tumor-targeting properties. The modified bacteria exhibit reduced ability to induce TNF-alpha and cause septic shock, making them safer for human use.
A comprehensive study reveals that new permanent press clothing, paints, floor finishes, wallpaper, and fingernail polishes can emit substantial amounts of formaldehyde. Low-level exposure can cause irritation, while long-term exposure may lead to respiratory difficulties and other health issues.
A commonly used sunscreen ingredient, PBSA, can damage DNA when exposed to sunlight, according to a recent study. The research suggests that this could lead to increased risk of developing skin cancer if similar damage occurs within skin cells.
Research by Japanese scientists found that beer inhibited the action of mutagens caused by suspected cancer-causing compounds, with stout beers showing the most potent effect. The study also showed that red and white wines, brandy, and Japanese sake had similar inhibitory effects.
Researchers developed a game to help close the gap between clinician and patient values in rehabilitation, finding that patients prioritize cognitive skills over physical skills early on but clinicians prefer full independence. The game identifies disparities in preferences across different stages of recovery.
Scientists at Johns Hopkins University have developed a new arsenal of medicines using monoclonal antibodies to prevent sexually transmitted diseases, gastrointestinal viruses, and the common cold. The antibodies can be produced in common field crops like corn and soy, making them potentially cheaper and more accessible.
A new sensor developed by Johns Hopkins researchers can detect minute traces of nerve agents sarin and soman in water, boasting sensitivity levels a million times greater than previous reported solutions. The sensor combines molecular imprinting with optical luminescence to achieve this remarkable detection capability.
Researchers at Cedars-Sinai Medical Center have developed a groundbreaking brain cell transplantation technique aimed at treating neurodegenerative diseases such as Parkinson's disease, stroke, and epilepsy. By selectively growing and implanting targeted brain cells, the team hopes to promote healing and repair damaged brain tissue.
