With cancer treatment, when a drug is given may matter almost as much as which drug is used. For years, melanoma researchers have faced a frustrating contradiction. Experiments suggested that periodically stopping certain targeted drugs might help keep resistant cancer cells in check. Yet when intermittent dosing was tested in patients, continuous treatment performed better. […]

Popular Fertility Drug May Raise Miscarriage Risk Without Improving Live Birth Odds
A widely used fertility drug may carry a hidden tradeoff: as treatment adds up, the risks may rise without improving the odds of a live birth. Researchers found that women exposed to higher cumulative doses of clomiphene citrate had progressively greater risks of miscarriage and multiple births, yet no corresponding improvement in the chance of […]
Scientists Survey Mount Ararat’s Mysterious Glacier for the First Time
A German and Turkish research team is studying a shrinking glacier as a record of past climate and environmental change. More than 5,000 meters above sea level, amid intense cold, strong winds, and oxygen levels roughly half those in the valley below, a German-Turkish research team conducted the first survey of Mount Ararat’s glacier in […]

Scientists Turn One of the World’s Hardest-To-Recycle Plastics Into Engine Oil
Polyvinyl chloride is one of the world’s most widely used plastics, but it is also difficult to recycle responsibly. Discarded PVC from pipes, window frames, and even credit cards could become a useful ingredient in synthetic lubricants instead of ending up in a landfill. Virginia Tech chemist and chemical engineer Guoliang “Greg” Liu and his […]
Scientists Have Uncovered a Troubling New Pattern Hidden in America’s Rivers
A river can now move nearly a year’s worth of sediment in just a few intense weeks. Across the United States, the sand, silt, and soil carried downstream by rivers are becoming increasingly concentrated into short, intense bursts, according to a new study that reconstructed nearly four decades of sediment transport across 175 waterways. The […]
