Researchers revise timing of Easter island’s societal collapse
The prehistoric collapse of Easter Island's monument-building society did not occur as long thought, according to a fresh look at evidence by researchers at...
Researchers demonstrate optical backflow of light
Researchers at Tel Aviv University have for the first time demonstrated the backflow of optical light propagating forward. The phenomenon, theorized more than 50...
Secondary forests provide deforestation buffer for old-growth primary forests
Currently, re-growing forests comprise roughly 21% of previously deforested areas in the Brazilian Amazon. However, these forests, referred to as secondary vegetation, have been...
Scientists grow date palm plants from 2,000-year-old seeds
Methuselah, Adam, Jonah, Uriel, Boaz, Judith and Hannah—all sat dormant in Judea since biblical times. Now scientists have resurrected them in the hopes of...
Closely spaced hydrogen atoms could facilitate superconductivity in ambient conditions
An international team of researchers has discovered the hydrogen atoms in a metal hydride material are much more tightly spaced than had been predicted...
Arctic permafrost thaw plays greater role in climate change than previously...
Abrupt thawing of permafrost will double previous estimates of potential carbon emissions from permafrost thaw in the Arctic, and is already rapidly changing the...
Making high-temperature superconductivity disappear to understand its origin
When there are several processes going on at once, establishing cause-and-effect relationships is difficult. This scenario holds true for a class of high-temperature superconductors...
New quantum switch turns metals into insulators
Most modern electronic devices rely on tiny, finely-tuned electrical currents to process and store information. These currents dictate how fast our computers run, how...
Team identifies low-energy solar particles from beyond Earth near the Sun
Using data from NASA's Parker Solar Probe (PSP), a team led by Southwest Research Institute identified low-energy particles lurking near the Sun that likely...
Quantum computers flip the script on spin chemistry
To build cheaper and more efficient sustainable energy options, we need to know a lot more than we currently do about the chemical reactions...
Astronomers search for gravitational-wave memory
Astronomers regularly observe gravitational waves (GW)—ripples in space and time—that are caused by pairs of black holes merging into one. Einstein's theory of gravity...
