Study reveals structures of six states of a rotary sodium ion pump
Six structures exhibited by the rotating sodium ion pump were reconstructed in 3D using cryo-electron microscopy. This analysis revealed that the rotor exhibits non-uniform rotation behavior due to partial structural interference with the stator comp.....»»
Tea science: Gene discovery to boost mechanical harvesting
Researchers have made significant strides in understanding the genetic factors influencing tea plant leaf droopiness, a key determinant of mechanical harvest success. By identifying the CsEXL3 gene and its regulation by CsBES1.2, the study paves the.....»»

New study unveils formation secrets of tiny rare earth elements
Researchers from Trinity College Dublin's School of Natural Sciences have revealed a novel route to the formation of bastnäsite, a crucial mineral for the extraction of rare earth elements (REEs). Their work offers promise in one day making the extr.....»»
Detecting intelligent life that"s light years away: Greenhouse gases could signal alien activity
If aliens modified a planet in their solar system to make it warmer, we'd be able to tell. A new UC Riverside study identifies the artificial greenhouse gases that would be giveaways of a terraformed planet......»»
Quantum state mixing in photobiology: New insight from ultrafast terahertz Stark spectroscopy
The membrane protein bacteriorhodopsin is a proton pump, in which proton transport is initiated by the light-induced isomerization of the chromophore retinal. The molecular quantum states involved in this ultrafast reaction have now been characterize.....»»
Global South health care practices contribute to spread of antimicrobial resistance across the world, study suggests
Many bacteria resistant to multiple antibiotics originate in Pakistan and other parts of the Indian subcontinent. Infections caused by these bacteria are challenging to treat; longer treatment with broad-spectrum antibiotics is required and despite t.....»»
Hidden mechanisms behind hermaphroditic plant self-incompatibility revealed
A new study presents an evolutionary-biophysical model that sheds new light on the evolution of the collaborative non-self recognition self-incompatibility, a genetic mechanism in plants that prevents self-fertilization and promotes cross-fertilizati.....»»
Beyond work: Study finds employment affects identity in late 20-somethings
For people in their late 20s, "Your job doesn't define you" is likely an unconvincing cliché......»»
Researchers identify potential hazards in biosolid fertilizers
Fertilizers manufactured from the sludgy leftovers of wastewater treatment processes can contain traces of potentially hazardous organic chemicals, according to a new study by Johns Hopkins University researchers......»»
Researchers use gold membrane to coax secrets out of surfaces
Using a special wafer-thin gold membrane, ETH researchers have made it significantly easier to study surfaces. The membrane makes it possible to measure properties of surfaces that are inaccessible to conventional methods......»»
Summer in the city: Climate science reveals the impacts of heat
The summer sun beats down. People without air conditioning must find refuge in schools and community centers. Outdoor workers struggle to keep cool. Hot nights interrupt people's sleep, not allowing them to get the rest needed to recover from the war.....»»
Squeezing more flavor: Genetic study optimizes citric acid in tomatoes
Citric acid (CA) is a flavor-enhancing compound in tomatoes that also serves as a metabolic pathway mediator. Despite its importance, the genetic and environmental interplay affecting its levels has been a puzzle, difficult to decipher and control......»»
Study finds strong path dependence in Plio-Pleistocene glaciations through climate model simulations
The climate modeling community has been particularly vexed by the glacial/interglacial cycles of the past three million years, when the Northern Hemisphere oscillated between times with and without large ice sheets......»»
Astronomers study evolution of a giant outburst in X-ray binary EXO 2030+375
An international team of astronomers has observed an X-ray binary system known as EXO 2030+375. Results of the observation campaign, presented in a research paper published June 18 on the pre-print server arXiv, provide more insights into the evoluti.....»»
Study: Teacher perceptions of chronically absent young students may add to the challenges of missing school
A new study finds that early elementary school teachers report feeling less close to chronically absent students and view them less positively, even when those students do not cause trouble in the classroom. This "cooling down" in the relationship be.....»»
Extreme wildfires doubled over past two decades: Study
The frequency and intensity of extreme wildfires has more than doubled worldwide over the past two decades as human activity has warmed the planet, said a new study published Monday......»»
What the 3.2 million-year-old Lucy fossil reveals about nudity and shame
Fifty years ago, scientists discovered a nearly complete fossilized skull and hundreds of pieces of bone of a 3.2-million-year-old female specimen of the genus Australopithecus afarensis, often described as "the mother of us all." During a celebratio.....»»
Rising health care prices are driving unemployment and job losses
Rising health care prices in the U.S. are leading employers outside the health care sector to reduce their payroll and decrease their number of employees, according to a new study co-authored by Yale economist Zack Cooper......»»
