A new study of a 2,200-year-old Roman shipwreck reveals that ancient sailors used sophisticated organic coatings to waterproof their vessels. Since the earliest seafaring journeys, people have needed ships that could resist saltwater, stay watertight, and endure damage from marine organisms such as worms. Despite this long history, research into non-wood materials used in ship […]

Enormous Prehistoric Insects Puzzle Scientists
The true reason ancient insects grew so huge just got a lot more mysterious. Three hundred million years ago, Earth looked nothing like it does today. The continents were joined into a single landmass called Pangaea. Around the equator, vast coal-swamp forests dominated the landscape. Oxygen levels in the atmosphere were much higher than they […]
The Most Effective Knee Arthritis Treatments Aren’t What You Expect
A sweeping analysis of nearly 10,000 patients challenges assumptions about how best to treat knee osteoarthritis. For many people with knee osteoarthritis, relief may not require medication. A large new analysis suggests that simple physical treatments can ease pain and improve movement, often more effectively than some high-tech options. Knee osteoarthritis is one of the […]

Scientists Develop Bioengineered Chewing Gum That Could Help Fight Oral Cancer
Bioengineered gum lowers HPV and harmful oral bacteria, offering a promising new approach for cancer prevention and treatment. Researchers led by Henry Daniell of the School of Dental Medicine at the University of Pennsylvania report that extracts from a bioengineered chewing gum can significantly lower levels of three microbes associated with head and neck squamous […]
After 37 Years, the World’s Longest-Running Soil Warming Experiment Uncovers a Startling Climate Secret
A decades-long experiment in a Massachusetts forest is uncovering unexpected behavior in soil carbon. After nearly 40 years, the longest-running soil warming experiment in the world is producing an unexpected finding. What was once considered long-term, “stable” carbon in forest soils is proving far less permanent. As temperatures rise, even these stubborn carbon reserves can […]
