Open Access: The Future of Academia

Plans to measure the impact of historical research as if it were a science will undoubtedly mean fewer history books that delight the general reader.The kind of history books that delight most readers probably incorporate original research with elegant, easily accessible prose: possibly a book such as Christopher Clark’s The Sleepwalkers or Lyndal Roper’s...

The Morality of Modern Medicine

Credit: European Directorate for the Quality of Medicines & HealthcareThe rise of laboratory science in the late 19th century placed a sharp focus on the moral value of medical innovation.'Modern medical science has offered us a choice where there was once none.' So stated John Simon at the International Medical Congress in London...

Something Mysteriously Eliminated About 90 Percent of Sharks 19 Million Years Ago

During this event, the populations of the predators abruptly dropped by as much as 90 percent, researchers report in the journal Science on June 4....

Meet the Fathers of Philosophy: Socrates, Plato and Aristotle

The School of Athens (1509–1511) by RaphaelTo this day, most of the Western way of thinking stems from the philosophical explorations of three men of Ancient Greece. Socrates, Plato, and Aristotle. No question you have heard of these philosophers. According to Hannah Fieldings, Award-Winning Romance Novelist, she started to investigate for her latest novel, Aphrodite's Tears, placed...

Uncovering Concealed Local States in a Quantum Material

Scientists have collected evidence of local symmetry breaking in a quantum material upon heating. They believe these local states are associated with electronic orbitals that serve as orbital degeneracy lifting (ODL) "precursors" to the titanium (Ti) dimers (two molecules linked together) formed when the material is cooled to low temperature. (Electron orbitals are considered...

Exploring Quantum Systems That Don’t Find Equilibrium

Some physical systems, particularly in the quantum world, do not reach stable equilibrium, even after long. An ETH researcher has now discovered a sophisticated description of this phenomenon.If a bottle of beer is placed in a huge bathtub loaded with icy water, it will not be long before you can enjoy a chilly beer....

Light Does the Twist for Quantum Computing

The discoveries, by Nagoya College researchers and colleagues in Japan and released in the journal Advanced Materials, allude to the development of materials and device methods used in optical quantum computing data processing.Photons are light particles with fascinating properties that can be explored for the storage and transportation of data and reveal tremendous promise...

The New Quantum Algorithm Surpasses the QPE Standard

Researchers boost their recently developed quantum algorithm, bringing it to one-tenth the computational price of Quantum Phase Estimation, and also utilize it to directly compute the vertical ionization energies of light atoms as well as molecules such as CO, O2, CN, F2, H2O, NH3 within 0.1 electron volts of accuracy.OSAKA, Japan. Quantum computers have...
