Depiction of the structural changes during 4-step unidirectional isomerization of 1st generation aldehyde motor with key features above the reaction arrows. Starting from top left, UV light induces photoisomerization to reach the top-right state with more than 95 percent efficiency. This top-right state transforms by a unidirectional thermal ‘helix inversion’ step (THI) to the version … Read more
A Long March-2F carrier rocket, carrying the Shenzhou-18 spacecraft and a crew of three astronauts, lifts off from the Jiuquan Satellite Launch Center. A spaceship carrying three astronauts from China’s Shenzhou-18 mission safely docked at Tiangong space station Friday, state-run media reported, the latest step in Beijing’s space program that aims to send astronauts to … Read more

The two test pilots will launch aboard Boeing’s Starliner capsule atop an Atlas rocket to the International Space Station, scheduled for liftoff on May 6, 2024. Credit: … Read more
The researchers investigated crystal structure and properties of perovskite-RbNbO3 prepared at 4 GPa. Single-crystal XRD analysis revealed RbNbO3 exhibits the same non-centrosymmetric space group as ferroelectrics BaTiO3 and KNbO3.

HXK, SnRK1 and TOR signaling networks in plant growth and development. Credit: The authors Sugar signaling is one of the most important regulatory signals for plant growth and development, and its metabolic network contains many regulatory factors. Sugar signaling molecules regulate cellular activities and organismal development by interacting with other intrinsic regulators and environmental cues. … Read more

Credit: Unsplash/CC0 Public Domain The deterioration of the UK’s natural environment could lead to an estimated 12% loss to GDP, according to new analysis. In comparison, the financial crisis of 2008 took around 5% off the value of the UK GDP, while the COVID-19 pandemic cost the UK up to 11% of its GDP in … Read more
The figure shows displacement effects for workers who make different types of occupation switches. Pre-displacement trajectories are reasonably similar between displaced and non-displaced workers. However, post-displacement career paths differ markedly. In particular, they depend on the type of occupation switch that displaced workers undertake.

Credit: Unsplash/CC0 Public Domain PFAS, or forever chemicals, are widespread and more likely to be found in public water systems serving low-income communities and communities of color in New Jersey, according to new research from Northeastern University. “This really comes out of a long tradition of environmental justice research that talks about the overburdened nature … Read more
Graphic abstract. Credit: Journal of Proteome Research (2024). DOI: 10.1021/acs.jproteome.3c00804 “Bookworm” is a cute thing to call a voracious reader, but actual bookworms—as well as microorganisms and time—break down the flour pastes commonly used to keep old publications in one piece. Now, researchers have analyzed the proteins in wheat-based glues applied in historic bookbinding to … Read more
