Among the hundreds of thousands of chemical compounds produced by plants, some may hold the key to treating human ailments and diseases. But recreating these complex, naturally occurring molecules in the lab often requires a time-consuming and tedious trial-and-error process. Now, chemists have shown how new computational tools can help them create complex natural compounds in a faster and more streamlined way. Read more ›

Over the last 20 years, large floods were associated with up to 24.9 percent higher death rates from major mortality causes in the U.S. compared to normal conditions. A new study demonstrates the sweeping and hidden effects of floods --including floods unrelated to hurricanes, such as those due to heavy rain, snowmelt, or ice jams. Read more ›

Scientists have developed an advanced swarm navigation algorithm for cyborg insects that prevents them from becoming stuck while navigating challenging terrain. The new algorithm represents a significant advance in swarm robotics. It could pave the way for applications in disaster relief, search-and-rescue missions, and infrastructure inspection. Cyborg insects are real insects equipped with tiny electronic devices on their backs -- consisting of various sensors like optical and infrared cameras, a... Read more ›

Protein aggregation is typical of various neurodegenerative diseases such as Alzheimer's, Parkinson's and prion diseases such as Creutzfeld-Jakob disease. A research team has now used new in vitro and cell culture models to show that a lipid anchor on the outer membrane of nerve cells inhibits the aggregation of the prion protein. Read more ›

Researchers have developed a non-invasive method to improve the effectiveness of chemotherapy while reducing its harmful side effects. By applying brief, localized pulses of magnetic fields, the team demonstrated a significant increase in the uptake of doxorubicin (DOX), a widely used chemotherapy drug, into breast cancer cells, with minimal impact on healthy tissues.

Collaborative work by amateur and professional astronomers has helped to resolve a long-standing misunderstanding about the composition of Jupiter's clouds. Instead of being formed of ammonia ice -- the conventional view -- it now appears they are likely to be composed of ammonium hydrosulphide mixed with smog. Read more ›

In the Arctic, the old, multiyear ice is increasingly melting, dramatically reducing the frequency and size of pressure ridges. These ridges are created when ice floes press against each other and become stacked, and are a characteristic feature of Arctic sea ice, an obstacle for shipping, but also an essential component of the ecosystem. In a recently released study scientists report on this trend and analyze observational data from three... Read more ›

A new study used acoustic sensors that detect the sound of gunfire to show how often children in one Chicago neighborhood are exposed to gunshots while walking to and from school. Results showed that nearly two-thirds of schools in the Englewood neighborhood of Chicago had at least one gun incident within 400 meters (about one-quarter mile) of where children were walking home during the 2021-22 school year.

Some of the most productive apple regions in America are facing big challenges from a changing climate, according to a new study. Researchers analyzed over 40 years of climate conditions that impact the growth cycle of apple trees from bud break and flowering through fruit development, maturation and color development. While many growing areas are facing increased climate risks, the top three largest apple producing counties in the U.S. were... Read more ›

Engineers have utilized quantum sensors to realize a groundbreaking variation of nuclear quadrupolar resonance (NQR) spectroscopy, a technique traditionally used to detect drugs and explosives or analyze pharmaceuticals. The new method is so precise that it can detect the NQR signals from individual atoms -- a feat once thought unattainable. This unprecedented sensitivity opens the door to breakthroughs in fields like drug development, where understanding molecular interactions at the atomic... Read more ›
