Novel silica nonwoven fabric scaffold enhances understanding of cell-to-cell interactions
Communication and coordination among different cells are fundamental aspects that regulate many functions in our body. This process, known as paracrine signaling, involves the release of signaling molecules by a cell into its extracellular matrix (EC.....»»
First visualization of valence electrons reveals fundamental nature of chemical bonding
The distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan. As the interactions between atoms are governed by the valence.....»»
Researchers shed light on how to make photopolymerization much more efficient
Polymers are materials made out of long, repeating chains of molecules, and it is the interaction between these chains that dictates most of a polymer's physicochemical properties. In accordance with this intuitive understanding of polymers, which da.....»»
Peering into the mind of artificial intelligence to make better antibiotics
Artificial intelligence (AI) has exploded in popularity. It powers models that help us drive vehicles, proofread emails and even design new molecules for medications. But just like a human, it's hard to read AI's mind......»»
New cobalt complex triggers ferroptosis in cancer cells
In programmed cell death, certain signaling molecules initiate a kind of suicide program to cause cells to die in a controlled manner. This is an essential step to eliminate damaged cells or to control the number of cells in certain tissues, for exam.....»»
Research team finds evidence of hydration on the asteroid Psyche
Using data from NASA's James Webb Space Telescope, a Southwest Research Institute-led team has confirmed hydroxyl molecules on the surface of the metallic asteroid Psyche. The presence of hydrated minerals suggests a complex history for Psyche, impor.....»»
A hopper could explore more than 150 km of Triton"s surface in two years
Neptune's largest moon, Triton, is one of the most biologically interesting places in the solar system. Despite being hard to reach, it appears to have active volcanoes, a thin atmosphere, and even some organic molecules called tholins on its surface.....»»
Wobbly molecules closer look with a new theoretical framework
While new technologies, including those powered by artificial intelligence, provide innovative solutions to a steadily growing range of problems, these tools are only as good as the data they're trained on......»»
New surfactant from cashew nut shell liquid boosts industrial reactions
Industries and chemical labs synthesize a wide variety of organic molecules every day. Most of these chemical reactions happen in the liquid phase to allow the substrates to interact easily. However, many substrates and catalysts are sensitive to wat.....»»
The biggest-ever sample of core material from Earth"s mantle could have valuable clues into the origins of life
If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then, enclosed within the mantle is the innermost metallic c.....»»
The Apple Watch SE may soon much-needed makeover
