Most asteroids are pretty predictable.
They just do what they’re told, pushed and tugged by external forces such as gravity or radiation pressure from the Sun.
Not 1998 KY26.
KY26 is hooning about like a ne’er-do-well – that is, accelerating in a way that defies expectations for how a well-brought-up asteroid ought to behave.
Working with the traces of thought instead of the process of thinking means AI systems are limited – and they limit their users, too.
Scientists have developed an electrically powered motor using a single molecule, drawing inspiration from the ancient Archimedes screw. The molecular machine can rotate when an electric voltage is applied, and researchers can reverse its direction by changing the voltage polarity.
Diamond Foundry grows a 200 mm single-crystal diamond that could bring the material closer to advanced semiconductor manufacturing.
An alternative model in which the universe is 26.7 billion years old and needs neither dark matter nor dark energy has held up against several major cosmology tests, according to a new University of Ottawa study. The research, titled “A Big Bang Nucleosynthesis Consistency Test of the CCC+TL Cosmology,” is published in the journal Universe.
During 2025 and 2026, Rajendra Gupta, adjunct professor in uOttawa’s Department of Physics, and postdoctoral researcher Dr. Nikolaos Samaras tested the CCC+TL model against a range of important astronomical observations.
CCC+TL stands for “covarying coupling constants plus tired light.” The model suggests that what is usually attributed to dark matter and dark energy could instead come from evolving fundamental constants that govern how forces and particles interact.
NASA has selected three companies for the next phase of an effort to provide a commercial replacement for its aging data-relay constellation.
Imagine a house where footsteps supposedly echo through the hallways at night and doors close in empty rooms.
If you had to spend a night there, would explanations involving old floorboards and drafts be enough to settle your doubts?
As it happens, trusting a scientific explanation doesn’t necessarily close the door on ghosts.
Physical Superintelligence claims its research system proved an 18-year-old quantum computing conjecture in three days.
As a liquid that is easily stored and transported, ammonia (NH3) is an attractive carrier for hydrogen, which is used in fuel cells, semiconductor manufacturing, chemical processing, and other applications. However, breaking ammonia into hydrogen and nitrogen typically requires high temperatures, and the resulting gas mixture must undergo additional purification before the hydrogen can be used in many applications.
MIT researchers have now developed an electrochemical approach to promote hydrogen release from ammonia while simultaneously separating and concentrating the hydrogen into a high-purity stream. Their strategy, which uses electricity to speed up the extraction, reduces the temperature and energy required to recover hydrogen from ammonia and other hydrogen carriers.
In a new study, the researchers showed that their approach can generate highly concentrated, pure streams of hydrogen.
Could inhibiting factor XIa prevent secondary stroke without increasing bleeding risk?
