Several Psychiatric Disorders Share The Same Root Cause, Study Suggests
Researchers have discovered that eight different psychiatric conditions share a common genetic basis.
A study published in early 2025 pinpointed specific variants among those shared genes, showing how they behave during brain development.
The US team found many of these variants remain active for extended periods, potentially influencing multiple developmental stages – and offering new targets for treatments that could address several disorders at once.
Immune checkpoint inhibitor therapies for cancer can induce unintended immune related adverse events (irAEs)
Here, Deepak A. Rao & team use mass cytometry immune profiling to identify T cell features in pre-treatment blood samples from patients that are associated with irAEs after ICI therapy.

Powering AI from space, at scale, with a passive tether design
Penn Engineers have developed a novel design for solar-powered data centers that will orbit Earth and could realistically scale to meet the growing demand for AI computing while reducing the environmental impact of data centers.
Reminiscent of a leafy plant, with multiple, hardware-containing stems connected to branching, leaf-like solar panels, the design leverages decades of research on “tethers,” rope-like cables that naturally orient themselves under the competing forces of gravity and centrifugal motion. This architecture could scale to the thousands of computing nodes needed to replicate the power of terrestrial data centers, at least for AI inference, the process of querying tools like ChatGPT after their training concludes.
Unlike prior designs, which typically require constant adjustments to keep solar panels pointed toward the sun, the new system is largely passive, its orientation maintained by natural forces acting on objects in orbit. By relying on these stabilizing effects, the design reduces weight, power consumption, and overall complexity, making large-scale deployment more feasible.
Real-time imaging reveals new mechanisms for pancreatic ductal establishment and remodeling
Abigail Laura Jackson, Silja Heilmann, Pia Nyeng (Roskilde Universitet – RUC) and colleagues use a new apical polarity reporter mouse & high-resolution live imaging to demonstrate that pancreatic tubulogenesis is driven by dynamic transformations of existing lumens, which establish and remodel the pancreatic duct.

Highly stable Cu₄₅ superatom could transform carbon recycling
After years of trying, scientists have finally created a stable superatom of copper, a long-sought-after chemical breakthrough that could revolutionize how we deal with carbon emissions.
Copper is a cheap and common metal, and because of its ability to bind carbon atoms together (C-C coupling), scientists have wanted to use it to turn carbon dioxide into products like ethylene for plastics and fuels. However, it corrodes or falls apart almost immediately when exposed to air or harsh industrial conditions.
A superatom is a cluster of atoms that behaves like a single atom, but with greater stability. In this new study published in the Journal of the American Chemical Society, scientists from Tsinghua University in Beijing built a nanocluster made from 45 copper atoms (Cu45).
