Since its introduction more than 150 years ago, the thought-provoking idea of Maxwell's demon has profoundly shaped our understanding of the relationship between information and energy. Maxwell's demon is an imagined microscopic ...
An international study has overturned a longstanding textbook view of how much energy animals use to travel, revealing that flying can sometimes be cheaper than swimming.
A University of Missouri astronomer is leading a team of 130 researchers from 62 institutions—including NASA, the California Institute of Technology, Princeton University and Harvard University—on an ambitious mission to ...
Einstein's theory of general relativity describes gravity as the bending of spacetime, a mathematical model that combines three-dimensional space and time into a single, four-dimensional continuum. The theory also predicts ...
Environmental DNA (eDNA) is increasingly being investigated by forensic scientists as a tool to help solve criminal cases that lack biological traces—and attention is also turning to collecting trace airborne eDNA left behind ...
The likely manipulation of citation numbers by research paper mills in high-impact cancer journals has been uncovered by an international team of academic researchers. Their findings point to an organized campaign to inflate ...
A few short years ago, asking AI to add two four-digit numbers together for a third-grade math assignment would have been a bad idea. Over half the time, the answer would be wrong, studies have shown. Long division or a "leaky ...
A new study led by researchers at ETH Zurich (Switzerland) and the Vrije Universiteit Brussel (Belgium) reveals that glaciers worldwide could lose ice faster than previously projected. Published in Nature Communications, ...
Identifying individual animals in the wild has long meant tagging, branding or clipping. For amphibians, the standard approach has often been toe-clipping, a procedure that can affect survival, physiology and behavior. A ...
Qubits, the quantum equivalent of digital bits, are fragile and prone to errors. That makes building reliable quantum computers extremely difficult. One fix has been to use traditional magic state distillation, which filters ...
