A microwave shield yields ultracold dipolar molecules
Almost a century ago, physicists Satyendra Nath Bose and Albert Einstein predicted a theoretical state of matter in which individual particles would, at extremely cold temperatures and low densities, condense into an indistinguishable whole. These so.....»»
iPhone 15 Pro gets direct record to external storage, but iPhone 15 has Lightning speeds
The iPhone 15 Pro got the unexpected bonus of allowing direct recording to an external drive — but at the same time, the regular iPhone 15 isn't getting any speed benefit from the switch to USB-C.Filmmakers can record to external storage, but only.....»»
Novel membrane could reduce energy expenditure in separating molecules for desalination, drug development
Separating molecules is critical to producing many essential products. For example, in petroleum refining, the hydrocarbons—chemical compounds composed of hydrogens and carbons—in crude oil are separated into gasoline, diesel and lubricants by so.....»»
Extending the playing field for organosulfur: A new way to synthesize sulfonate esters
Organosulfur compounds are organic molecules that contain one or more sulfur atoms bonded to carbon atoms. They not only play fundamental roles in biological processes but also have wide applications in many industries, such as pharmaceuticals, agroc.....»»
Agriculture study on cover crops mixtures delivers unexpected results
Farmers usually plant cover crops after harvesting their main crop. This prevents erosion of the soil and nutrient leaching. The roots of these crops also stabilize the structure of the soil. It had been assumed that a mixture of different cover crop.....»»
Novel device combines nanopores with electronic signals for disease detection
In living organisms, cells have a very high capacity to process and communicate information by moving molecules or ions through tiny channels that span the cell membrane. UC Santa Cruz Professor of Electrical and Computer Engineering Marco Rolandi's.....»»
Ever wonder how your body turns food into fuel? Researchers tracked atoms to find out
Inside our bodies at every moment, our cells are orchestrating a complex dance of atoms and molecules that uses energy to create, distribute and deploy the substances on which our lives depend......»»
Scientists synthesize new organometallic "sandwich" compound capable of holding more electrons
Organometallic compounds, molecules made up of metal atoms and organic molecules, are often used to accelerate chemical reactions and have played a significant role in advancing the field of chemistry......»»
If Earth were an exoplanet, JWST would know there"s an intelligent civilization here
If we're going to look for life on other worlds, why not start with the one planet we know has life? Earth's atmosphere is rich with oxygen and molecules such as methane, which strongly suggest the presence of life. It also has traces of molecules su.....»»
Prepare for unexpected power outages with these essential safety tips from Bluetti
It is officially hurricane season, and with winter looming around the corner, it's the perfect time to talk about navigating a natural disaster. Portable power station maker Bluetti brings you a comprehensive safety guide to keep you safe when the un.....»»
AI "nose" predicts smells from molecular structures
In a major breakthrough, scientists have built a tool to predict the odor profile of a molecule, just based on its structure. It can identify molecules that look different but smell the same, as well as molecules that look very similar but smell tota.....»»
How hydrophobicity shapes protein assemblies
Through a nuanced balance of electrical and hydrophobic forces, biological molecules self-assemble into the large functional structures that maintain life's vital functions. Understanding how proteins self-assemble requires knowledge of both forces......»»
Inhalable molecules neutralize SARS-CoV-2 in mice
Nanofitins, which are derived from a protein found in Sulfolobus acidocaldarius—an archaeal microorganism found in hot springs—successfully neutralized SARS-CoV-2 in mice and were well-tolerated. When inhaled by the rodents, the engineered nanofi.....»»
Surpassing the human eye: Machine learning image analysis rapidly determines chemical mixture composition
Have you ever accidentally ruined a recipe in the kitchen by adding salt instead of sugar? Due to their similar appearance, it's an easy mistake to make. Similarly, checking with the naked eye is also used in chemistry labs to provide quick, initial.....»»
PC sales could be set for an unexpected recovery soon
While figures are still declining this year, 2024 looks to be the start of the PC’s return as budgets increase......»»
Scientists confirm decades-old theory of non-uniform distribution of electron density in aromatic molecules
Scientists from the Institute of Organic Chemistry and Biochemistry Prague, the Institute of Physics of the Czech Academy of Sciences, and Palacký University Olomouc, have once again successfully uncovered the mysteries of the world of molecules and.....»»
For a new approach to fighting malaria, study focuses on special RNA molecules in human malaria parasite
The mosquito-borne infectious disease malaria resulted in about 241 million clinical episodes and 627,000 deaths in 2020. In young children and pregnant women living in areas where the disease is endemic, a major cause of death is Plasmodium falcipar.....»»
Researchers take aim at weather forecasters" biggest blind spot
Anyone who's been caught in an unexpected downpour knows that weather forecasting is an imperfect science. Now, researchers at Stevens Institute of Technology are taking aim at one of meteorologists' biggest blind spots: extremely short-term forecast.....»»
Researchers produce polymers from ballbot-type carbenes for the first time
N-heterocyclic carbenes (NHCs) are small, reactive ring molecules that bond well with metallic surfaces, and which over the past few years have attracted a great deal of interest in the field of the stable chemical modification of metallic surfaces......»»
Quantum computer unveils atomic dynamics of light-sensitive molecules
Researchers at Duke University have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecule.....»»
