Nanoscale tech tracks proteins inside living neurons to guide Alzheimer's and Parkinson's drug discovery‎

A technology developed at The University of Queensland allowing scientists to observe how disease-related proteins behave inside living neurons will be used to advance early drug discovery for neurodegenerative diseases. The NASTIC (Nanoscale Spatiotemporal Indexing Clustering) platform, spun out into Brisbane-based startup Accretion Bio, enables researchers to study real-time biological processes in living cells across space and time at the single-molecule level for the first time.

New 4D biofabrication technology holds promise for tissue engineering, wound healing‎

If you've ever created a snowflake by folding, cutting and unfolding a piece of paper, you've practiced the art of kirigami. Like origami, kirigami has inspired innovations far beyond the elementary school classroom, with applications ranging from deployable structures for spacecraft to semiconductors.

Molecular switch controls how cells load cargo for recycling‎

Cells constantly recycle proteins and other cellular components. But how do they ensure that the right cargo ends up in the right recycling vesicle—one of the cell's transport carriers? A team at the University of Basel has identified a molecular switch that controls this process. The small protein ARF-1 ensures that recyclable cargo is efficiently loaded into transport vesicles and returned to the cell's surface.

13% of Earth's land identified as biodiversity conservation hotspots‎

As governments prepare to gather in Yerevan, Armenia, this week for the U.N. Biodiversity Conference (COP17), new research identifies 13% of Earth's land area as hotspots for biodiversity conservation, highlighting where conservation efforts are most urgently needed.

How much of a basin's drainage network should flood models capture?‎

As climate change is expected to increase the risks associated with extreme rainfall and flooding, managing floods requires approaches beyond conventional infrastructure such as dams and reservoirs.

Forgotten particle could answer mystery of why we exist, say physicists‎

Scientists have unveiled a new theory on the birth of the cosmos, suggesting the early universe was shaped by an ancient particle that has been overlooked for decades.

Criminal justice researchers use statistical modeling to examine wrongful-conviction risk‎

A University of Mississippi study is adding nuance to a debate over how often police interrogation tactics can produce false confessions leading to wrongful convictions. In a recent simulation study published in the Journal of Criminal Justice, Ole Miss criminal justice and legal studies professors Mary Catlin and Thomas Bryan Smith found that the predicted likelihood of a false confession grows with the length of a police interrogation.

Planetary 'twins' Uranus and Neptune may have different origin stories‎

By indirectly probing the depths of Uranus and Neptune's atmospheres, an international team of scientists has revealed a significant contrast in their chemical composition. Neptune appears to be more enriched in oxygen than Uranus. These results suggest that the two ice giants may have formed in different regions of the primitive solar system before reaching their current orbits, calling into question the idea of a common origin for these two planets, often considered twins.

Researchers unlock new way to map molecular structure on surfaces‎

Scientists at NPL, with the University of Surrey, University of Oxford, the Francis Crick Institute and IONTOF GmbH, have developed a technique to distinguish and map molecules that share the same chemical formula and mass but have different structures and functions. The research is published today (Oct. 19) in Nature Communications.
