New models shed light on life's origin

The first signs of life emerged on Earth in the form of microbes about four billion years ago. While scientists are still determining exactly when and how these microbes appeared, it's clear that the emergence of life is ...

Scientists develop AI-based method to predict RNA modifications

A team of researchers from the Agency for Science, Technology and Research (A*STAR) and the National University of Singapore (NUS) has developed a software method that accurately predicts chemical modifications of RNA molecules ...

Blood stem cells found to not be in charge in an emergency

As long as we are healthy, our body keeps the number of blood and immune cells largely constant. However, any infection or other disorder that increases cell consumption results in cell loss, which must be replaced as quickly ...

Dynamical fractal discovered in clean magnetic crystal

The nature and properties of materials depend strongly on dimension. Imagine how different life in a one-dimensional or two-dimensional world would be from the three dimensions we're commonly accustomed to. With this in mind, ...

Enhancing earthquake detection from orbit

When a major earthquake strikes, nearby seismometers can inform rapid alerts to residents and emergency services that potentially hazardous shaking or tsunamis may be headed their way. However, local seismometer measurements ...

Photonics chip allows light amplification

The ability to achieve quantum-limited amplification of optical signals contained in optical fibers is arguably among the most important technological advances that are underlying our modern information society. In optical ...

Local floodplain home buyouts can inform federal plans

As climate change threatens residential areas, a longtime federal home buyout program—designed to eliminate risk to people and property—has become bureaucratically inaccessible and inequitable.
