New hybrid films could cut costs for direct X-ray detectors‎

In medicine, security, nuclear safety and scientific research, X-rays are essential tools for seeing what remains hidden. The materials used to create X-ray detectors can be rigid, expensive and laborious to produce. But new research led by FSU Department of Chemistry and Biochemistry Professor Biwu Ma is creating lower-cost, adaptable materials that could revolutionize X-ray detection technologies.

Saving seagrass and French oysters: Fresh solutions breathe new life into Europe's coastal areas‎

European coastal areas are under increasing pressure. Researchers are investigating ways to reverse this trend and help communities adapt to climate change. From Arctic fjords to Mediterranean seagrass meadows, centuries of human activity have damaged habitats that were once full of life.

Climate 'fingerprints' mark human activity from the top of the atmosphere to the bottom of the ocean‎

The world is warming. This fact is most often discussed for Earth's surface, where we live. But the climate is also changing from the top of the atmosphere to the bottom of the ocean. And there is a clear fingerprint of humanity's role in causing these changes through greenhouse gas emissions, primarily from burning fossil fuels.

Why does this river slice straight through a mountain range? After 150 years, scientists finally know‎

The western U.S. is a geologists' dream, home to the Rocky Mountains, the Grand Canyon, active volcanoes and striking sandstone arches. But one landform simply doesn't make sense.

New type of magnetism discovered in 2D materials‎

In collaboration with international partners, researchers at the University of Stuttgart have experimentally demonstrated a previously unknown form of magnetism in atomically thin material layers. The discovery is highly relevant for future magnetic data storage technologies and advances the fundamental understanding of magnetic interactions in two-dimensional systems. The results have now been published in Nature Nanotechnology.

Saturday Citations: Imaginative bonobos; cannabis brain benefits; sneaky beetles‎

This week in science news: Nitrous oxide, a potent greenhouse gas, may break down more rapidly in the atmosphere than previously thought due to climate change. A new, experimental pill dramatically reduces bad cholesterol. And physicists believe they detected an exploding black hole, representing scary new behavior from what we once thought was a more limited arsenal of gravity-based terror and awe.

Mathematical model sheds light on African American family ties‎

Calling a friend "cousin" might not be just a term of affection among some African Americans. Now, a mathematical model shows that there is a good chance there is some type of family connection between 185 and 410 years ago for many pairs of African Americans of the same age.

Fresh and healthy food can be difficult for some Montrealers to access, study shows‎

Fresh, affordable and nutritious food is an essential human need. But for many city-dwellers, accessing it can be difficult and time-consuming, especially for those who are elderly or have mobility challenges. This is true even in Montreal, a city that prides itself on its active transportation network and compact population distribution.

Wildfire prevention models miss key factor: How forests will change over decades‎

Eucalyptus trees, laden with flammable oils, could spread into Portugal's south-central region by 2060 if changing climate conditions make the area more hospitable to their growth, creating wildfire hotspots that would evade detection by conventional prevention approaches.
