Lettuce grown under artificial lights isn’t just affected by temperature and water—how much light it gets also shifts how it processes nitrogen, the stuff that makes greens healthy. Scientists grew two types of lettuce, one crispy like a sandwich topping and one loose-leaf for salads, under two ligh
Illinois is seeing more dust storms these days, and they’re not just an annoyance—they’re a serious danger. Strong winds can lift dry soil from farm fields, creating sudden walls of dust that reduce visibility to almost zero. These storms can appear quickly, turning highways into risky zones for dri
ICU nurses deal with unique challenges every day. A study in Iran asked fourteen experienced ICU nurses to share the biggest barriers they face at work. The nurses pointed to eighteen main issues, which were grouped into five areas: the physical space, the tools they use, the tasks they perform, the
Farmers in New Jersey and Pennsylvania are bracing for a tough season ahead. After a sudden heatwave in mid-April followed by unexpected freezes just days later, many fruit crops are struggling to recover. Peaches, apples, and even some berries were hit hard, with some farms losing most of their pro
This grass isn’t just sitting around waiting to die—it’s actively planning its next move. Egyptian crowfoot grass, a tough C4 weed, doesn’t play fair with crops like rice or sugarcane. Scientists tested how this plant handles tough conditions like temperature swings, salty soil, and dry spells. Unde
Nebraska has been warmer and drier than usual since the start of the year. This dry spell has helped some areas grow, but it also means farmers and ranchers in the western part of the state are worried. Those places saw large grass fires last summer, and new fires have popped up again in the past we
Florida is rolling out a new history course this fall, one that skips the traditional AP U. S. history route. Instead of using the College Board’s well-known program, the state created its own version called FACT U. S. History. The goal? To give students another way to earn college credit while avoi
Back in 2003, a simple checklist was made to help doctors spot neck pain that shoots down the arm. The checklist looks for four clues: pain that moves when you lift your arm, a specific spot of numbness in one finger, a weak muscle in your arm, and a certain test that makes the pain travel when your
Barley doesn’t always wait to be harvested. Sometimes, rain before cutting triggers premature sprouting in the field, turning starch into sugar and ruining quality. Scientists have now found small genetic differences that help some barley plants resist this problem, called preharvest sprouting. Inst
When someone in the ICU has a breathing tube, their voice box often gets damaged. This can cause big problems like food or liquid going down the wrong way or weak coughs. Normally, doctors check these issues with stethoscopes or guesswork, which isn’t always reliable. But new tools like tiny scopes
