How a molecular machine is assembled to convert light to food for plants
The conversion of light into chemical energy by plants and photosynthetic microorganisms is one of the most important processes in nature, removing climate-damaging CO2 from the atmosphere. Protein complexes, so-called photosystems, play the key role.....»»
New data science tool greatly speeds up molecular analysis of our environment
A research team led by scientists at the University of California, Riverside, has developed a computational workflow for analyzing large data sets in the field of metabolomics, the study of small molecules found within cells, biofluids, tissues, and.....»»
Light momentum turns pure silicon from an indirect to a direct bandgap semiconductor
UC Irvine-led research reveals that the optical properties of materials can be dramatically enhanced—not by changing the materials themselves, but by giving the light new properties......»»
How a bacterial pathogen that causes dysentery manipulates molecular activity to assure its survival
Virginia Tech researchers have learned how bacteria manipulate molecules to infect the host organism. Daniel Capelluto and his research team have discovered the mechanism by which the bacterial pathogen Shigella flexneri, the causative agent of dysen.....»»
New database covers distribution and evolutionary history of megadiverse flowering plant family on isolated islands
Asteraceae, a family of flowering plants, are the most diverse group of flowering plants in the world. This plant family comprises about 34,000 species. An international research team with the participation of the University of Göttingen has now com.....»»
Double-edged STING: A new pathway involved in aging
A protein called STING, previously shown to control a pathway that contributes to antiviral signaling, also plays an important role in cellular stress clearance and cell survival, according to a new paper published in Molecular Cell......»»
Plants could still grow well under alien skies
Photosynthesis changed Earth in powerful ways. When photosynthetic organisms appeared, it led to the Great Oxygenation Event. That allowed multicellular life to evolve and resulted in the ozone layer. Life could venture onto land, protected from the.....»»
Hubble lights the way with new multiwavelength view of galaxy NGC 1559
The magnificent galaxy featured in this NASA/ESA Hubble Space Telescope image is NGC 1559. It is a barred spiral galaxy located in the constellation Reticulum, approximately 35 million light-years from Earth. The brilliant light captured in the curre.....»»
Research highlights the unseen challenges, adaptations of adult daughters during COVID upheaval for families
A Baylor University study has shed light on the often-overlooked experiences of women doing "daughtering" in families, particularly during the COVID-19 pandemic, which created immense challenges in their relationships with parents and other family me.....»»
Forever chemicals persist through waste incineration, researcher finds
PFAS, often called "forever chemicals," present in municipal solid waste can survive the high temperatures of waste incineration and continue to spread into the environment via residues from waste-to-energy plants......»»
Researchers achieve aluminum molecular ring-based rotaxane and polyrotaxane
Rotaxanes have garnered interest for their unique structures consisting of mechanically interlocked axles and macrocycles. Numerous organic macrocycles have been employed to construct rotaxanes, including crown ether, cyclobis(paraquat-p-phenylene),.....»»
Exploring the interplay between phosphate signaling and jasmonate pathways in tea plants
Catechins, the key active components in tea, are known for their protective effects against conditions like diabetes, cancer, and cardiovascular diseases. However, their biosynthesis is highly sensitive to environmental factors, particularly phosphat.....»»
Astronomers just detected the biggest black hole jets ever seen—and named them Porphyrion
The largest known black hole jets, 23 million light years across, have been discovered in the distant universe. This pair of particle beams launched by a supermassive black hole is over a hundred times larger than our galaxy, the Milky Way......»»
Observers detect intraday variability of blazar 1ES 1426+42.8
Astronomers report the detection of optical intraday variability of a blazar known as 1ES 1426+42.8. The new findings, presented in a paper published in the September issue of Monthly Notices of the Royal Astronomical Society, could shed more light o.....»»

Homeopathic company refuses to recall life-threatening nasal spray, FDA says
Consumers should stop using SnoreStop, FDA says. Enlarge (credit: Getty | Florian Gaertner) The maker of a homeopathic nasal spray with a history of contamination is refusing to recall its product after the Food and Drug.....»»
Supply issue halting production at Chevy Silverado plant
GM didn't provide details about the supply issue, which will shut Fort Wayne Assembly and three components plants in Michigan and Indiana for the week of Sept. 23......»»
Research predicts rise in tropical hydraulic failure
Hydraulic failure in tropical environments is expected to increase, according to new research published in New Phytologist. As weather patterns change and temperatures rise, plants will need to adapt in order to survive. Hydraulic failure occurs when.....»»
Convergent evolution study sheds light on how new genes arise
Where do new genes come from? That's the question a team of biological sciences researchers from the U of A set out to answer in a new study......»»
How plants keep viruses from passing to their progeny
Scientists have learned how plants keep viruses from being passed to their offspring, a finding that could ensure healthier crops. The discovery could also help reduce the transmission of diseases from mothers to human children......»»
Visible-light-antenna ligand enhances samarium-catalyzed reactions
Samarium (Sm), a rare earth metal, is important to organic chemists because of the ability of its divalent compounds to efficiently perform single-electron transfer reductions......»»
