A newly discovered galactic structure is so large that it means one of our basic assumptions about the nature of the universe could be wrong.
Just outside of Jerusalem, archaeologists have discovered a cache of vessels and figurines inside a 2,750-year-old temple that could provide a rare window into religious rituals of the period, the Israeli Antiquities Authority announced. The finds were uncovered at Tel Motza, an archaeological site being excavated ahead of the expansion of Highway 1, the main…
Researchers from the Laboratoire Leprince-Ringuet have carried out the first measurement of the intensity of the diffuse extragalactic background light in the nearby Universe, a fog of photons that has filled the Universe ever since its formation. Using some of the brightest gamma-ray sources in the southern hemisphere, the study was carried out using measurements…
Summer storms may create new holes in our protective ozone layer as Earth heats up—bringing increased solar ultraviolet radiation to densely populated areas, a new study says. What’s more, if more sunlight reaches Earth, skin cancer could become the new marquee risk of global warming. As the planet warms, some studies have suggested summer storms…
Scientists have built a quantum computer in a diamond, the first of its kind to include protection against “decoherence” — noise that prevents the computer from functioning properly. The demonstration shows the viability of solid-state quantum computers, which – unlike earlier gas- and liquid-state systems – may represent the future of quantum computing because they…
The idea for an eternal clock that would continue to keep time even after the universe ceased to exist has intrigued physicists. However, no one has figured out how one might be built, until now. Researchers have now proposed an experimental design for a “space-time crystal” that would be able to keep time forever. This…
The following is from a guest post to the Chronicle’s WorldWise blog, written by John D. Holm, the former director of the Office of International Education and Partnerships at the University of Botswana and director of international programs at Cleveland State University: International-development experts have expressed much concern about the brain drain of African scholars…
