Phys.org / Untangling the meta-biomaterial puzzle one property at a time

From repairing damaged tissues to developing better implants, many medical developments depend on materials that can mimic the complex properties of human tissue. Meta-biomaterials are among the most promising candidates. ...

Phys.org / Tiny molecular rings open new ways for designing better medicines

Cyclopropanes are organic chemistry's smallest rings. Three carbon atoms are joined in a triangle, creating a compact and unusually strained structure. Despite—or partly because of—this unusual geometry, cyclopropanes are ...

Phys.org / Hubble and Webb find that far-out solar system objects 'remember' the past

For the first time, scientists used the combined power of NASA's Hubble and James Webb Space Telescopes to study some of the most far-flung bodies in our solar system, trans-Neptunian objects (TNOs). Some are the smallest ...

Phys.org / Sparse-data method estimates sea surface temperatures 40% more accurately than conventional approach

Researchers have developed a method for extrapolating sea surface temperatures from sparse data that is significantly more accurate than other commonly used computational methods and slightly more accurate than the best-performing ...

Phys.org / Cosmic radiation at flight altitudes rises when the sun is less active

Radiation from space is constantly entering Earth's atmosphere, but how much of it reaches the altitudes used by commercial aircraft depends not only on height and location, but also on the activity of the sun. A new study ...

Phys.org / New screening system flags food-packaging chemicals linked to serious health risks

Packaged food usually sits in plastic-lined bags designed to keep air, moisture and contaminants out. That same protection can also increase the chances of chemicals from the packaging seeping into the food. When a chemical ...

Phys.org / Waterlogged seeds reveal melons' ancient journey

Melons produce many seeds, making the melon shape a traditional symbol of fertility and prosperity in Chinese culture. But the historical debate about how melons made their way to modern tables is as long and twisted as ...

Phys.org / A crystalline sponge reveals structures of large 'beyond rule of 5' molecules

Drug discovery has traditionally followed the "rule of 5," which identifies chemical properties generally associated with good absorption of orally administered drugs, including a molecular weight below 500 daltons (Da). ...
