Cornell researchers use game theory to show that weak AI regulations may backfire, potentially causing greater risks than no regulation at all. A new Cornell University analysis uses game theory to warn that ill‑crafted AI rules might undermine safety...

theoretical frameworks. By juxtaposing experimental findings with predictions derived from quantum chromodynamics (QCD)—the theory governing the strong nuclear force—researchers refine their understanding of quark and gluon behavior under extreme...

co‑author. “Other galaxies weren’t breaking the laws of physics—we were measuring them with the wrong yardstick.” (Left) Theory predicts (blue, solid) that an increase in the sound speed shown with a 37% increase will increase the break masses compared...

in Nature, forces a reclassification of zhelestids. Rather than being early ancestors of modern placental mammals—a theory built almost entirely on tooth morphology—these creatures have been reassigned to the Zalambdalestoidea, an extinct lineage of...

into silence after being struck, the newly formed black hole emits gravitational waves as it stabilizes. While Einstein’s theory of general relativity posits that these black holes are simple objects defined primarily by their mass and rotation,...

fewer of these remains, yet there is no evidence of an abrupt abandonment. Gradual Crop Adaptation Replaced Sudden Collapse Theory These results undermine models that attribute the Harappan decline to a catastrophic monsoon failure around 4,100 years...

initial interactions set the tone for future relationships and can help alleviate early resistance. 2. Social Identity Theory Leaders can foster team cohesion by emphasizing shared goals, values, and a collective identity. When employees feel a sense of...

paper, merging the gravitational‑wave signal with the host‑galaxy information enabled a direct application of Einstein’s theory of gravity to compute the expansion rate. The initial result fell midway between the competing estimates, leaving the tension...

bell. Within this decaying signal, investigators identified a weak, rapidly diminishing component called a direct wave. Theory had long predicted its presence, but previous detectors lacked the sensitivity to separate it from background noise. Neil Lu...

moons. The current inner moons and ring material are, in this view, the recycled remains of those vanished worlds. This theory effectively explains why Neptune’s system appears so distinct from those of its gas giant counterparts. Before the arrival of...

blamed for the memory loss observed in neurodegenerative conditions like Alzheimer’s disease. To test the limits of this theory, the research team induced artificial hibernation in mice, a process that significantly lowers body temperature and...

Olefins. Credit: Science Strain Versus Impossibility To confirm their findings, the researchers employed density functional theory to calculate the energy state of the [2.2.1] anti-Bredt olefin. The analysis revealed a significant olefin strain energy...

almost intact within mere hours of a massive collision between Earth and the protoplanet Theia. For decades, the dominant theory of lunar formation has painted a picture of a gradual, messy process: a Mars-sized world named Theia slams into the...

©arXiv:2606.19171 To explain these observations, the researchers turned to quantum electrodynamical density functional theory. Their calculations indicate that photon coupling effectively redistributes spectral weight within the Eliashberg function—a...

S301 holds the potential to solve a long-standing mystery: the rotation rate of Sagittarius A*. Under Einstein’s general theory of relativity, a spinning mass like a supermassive black hole generates an effect known as frame dragging, or the...
