His model of gravity showed that Newtonian gravity, which has dominated astronomy and physics…

Lattice QCD method suggests simpler spectra of exotic XYZ hadrons
This diagram shows the contours of a complex energy surface. Each color corresponds to a different pair of D mesons. Although their shapes are very different, they revolve around a common vertex. This means that there is a single resonance coupled to all three channels. Credit: Jefferson Lab Illustration/David Wilson The elusive particles that first formed in the hot, dense…

Asset owners may encourage investment in climate change mitigation, research suggests
Credit: Pixabay/CC0 Public Domain Asset owners, who control substantial capital in the financial system through pension funds, endowments, foundations, and private holdings, can help drive investments in climate change mitigation, according to a new study from the Yale School of the Environment. It may play an important role. The study, led by researcher Emil Moldovan, asked owners of large asset…

Earth experienced a period of massive and rapid melting after the last ice age, new research suggests
Credit: CC0 Public Domain At the end of the last global ice age, the frigid Earth reached a pre-built limit of climate change and melted into a slimy planet. The results of the Virginia Tech-led study show direct evidence of a slushy planet (also known as the “Plume World Ocean” era), when sky-high carbon dioxide concentrations sent the frozen Earth…

Ion engines could take us to the Sun’s gravitational lens within 13 years, paper suggests
ion thruster. Credit: NASA Sending objects to other stars is still science fiction. But with some specific missions, you might be able to get at least halfway there. These “interstellar precursor missions” involve trips to the Sun’s gravitational lensing point, which is 550 astronomical units from the Sun. This is further away than any previous man-made object, including Voyager. Getting…

Abiotic organic synthesis research suggests new mechanism of organic condensation
Manned Vehicle (HOV) Shen Hai Yongshi. Credit: NIGPAS A Chinese research team reported the discovery of abiotic organic compounds in the oceanic crust of the Southwest India Ridge and proposed a molecular mechanism for organic condensation. This groundbreaking discovery follows the discovery in 2021 of nanoscale abiotic organic matter in mantle rocks in the Yap Trench. This represents an important…

Easter Island’s volcanic history suggests that Earth’s mantle behaves very differently than previously assumed
The structure of the mantle plume beneath Easter Island. Credit: Douwe van Hinsbergen Geography textbooks describe the Earth’s mantle, which lies beneath the plates, as a well-mixed, viscous rock that moves with the plates like a conveyor belt. But this idea was first broached about 100 years ago, and it’s surprisingly difficult to prove. A mysterious discovery on Easter Island,…

Assessment of damaged archaeological sites suggests that separate conservation concepts are needed
The rebuilt walls of the small fort of Nettersheim on the Steinrütsch River could not withstand the water. In addition, one of the rebuilt gate areas had been poorly cleaned and was partially sagging, leading to settlement cracks. Credit: University of Cologne An analysis of damage to archaeological sites documented after heavy rains in parts of Germany in July 2021…

Arctic plant research suggests rate of climate change threatens to outstrip species’ ability to adapt
Arctic Siberian Primrose. Credit: Annina Mattila A research group at the Finnish Museum of Natural History is investigating the adaptive capacity of plant species in a warming climate. Their recent research examines the Siberian primrose, a plant species that lives on the coasts of the Gulf of Bothnia and the Arctic Ocean. Climate change threatens the survival of species. The…

North Sea oil pollution is ‘significantly underestimated’, new report suggests
Credit: Unsplash/CC0 Public Domain Growing up in Aberdeen, Scotland, the shadow of the Piper Alpha disaster loomed large over our community. A tragic explosion on an oil drilling platform in 1988 claimed the lives of 167 people. At that time, I was fortunate not to know about the impact that disaster would have on the ecosystem. However, the 670 tonne…
