Ultrafast electron imaging captures never-before-seen nuclear motions in hydrocarbon molecules excited by light
The interactions between light and nitroaromatic hydrocarbon molecules have important implications for chemical processes in our atmosphere that can lead to smog and pollution. However, changes in molecular geometry due to interactions with light can.....»»
Gurman: Apple-designed 5G modem coming to 2025 iPhones will be worse than Qualcomm’s
Apple’s long-in-the-works project to build its own cellular modem is about to see the light of day. As multiple reports have indicated in the past, select 2025 iPhone models will carry the Apple 5G modem—but thanks to a new report, now we know it.....»»
Developing a cyclic molecule that captures phosphate in harmony with water molecules
Researchers at University of Tsukuba, Osaka University, and Kitasato University developed a novel amide cyclodextrin (cyclic oligosaccharide) that can selectively capture phosphate ions in water. In addition, the researchers revealed the mechanism by.....»»
Experiments provide evidence that interaction of light with a hydrocarbon molecule produces strained molecular rings
When molecules interact with ultraviolet (UV) light, they can change shape quickly, producing strain—stress in a molecule's chemical structure due to an increase in the molecule's internal energy. These processes typically take just tens of picosec.....»»
Stochastic model captures microbiome interactions more precisely
Traditional models for analyzing microbial communities often rely on average microbial abundance over time. While these models can predict temporal changes effectively, they often fail to capture the actual interactions between microbes......»»
Discovery of key protein complex shows evolution and adaptability of photosynthetic organisms
A team of researchers has revealed the structure of a modified and evolved version of Photosystem I (PS I), a key protein complex used by plants and cyanobacteria to convert sunlight into chemical energy. This discovery sheds light on the evolution a.....»»
Researchers reveal the mechanism of runaway electron generation in tokamak fusion reactors
A research team has clarified the mechanism behind the generation of runaway electrons during the startup phase of a tokamak fusion reactor. The paper, "Binary Nature of Collisions Facilitates Runaway Electron Generation in Weakly Ionized Plasmas," w.....»»
Spectroscopy and AI method provide unique window into protein structure and mechanism of action
The lab of Hassane Mchaourab, director of the Center for Applied Artificial Intelligence in Protein Dynamics and professor of molecular physiology and biophysics, has developed a methodological blueprint that couples experimental double electron–el.....»»
Proposed wastewater release into Cape Cod Bay likely to remain for at least one month, study finds
Scientists at the Woods Hole Oceanographic Institution (WHOI) investigating the pathways of the proposed wastewater discharge from the Pilgrim Nuclear Power Station (PNPS) find it has a high probability of remaining in Cape Cod Bay for at least one m.....»»
Polarization photodetector that mimics desert ant offers pathway for more sensitive, miniaturized imaging systems
Polarization photodetectors (pol-PDs) have widespread applications in geological remote sensing, machine vision, and biological medicine. However, commercial pol-PDs usually require bulky and complicated optical components and are difficult to miniat.....»»
The Amazon rainforest as a cloud machine: How thunderstorms and plant transpiration produce condensation nuclei
The rainforest in the Amazon basin transpires vast amounts of gaseous isoprene. Until now, it was assumed that this molecule is not transported far up into the atmosphere, as it rapidly declines when exposed to light conditions. The CAFE-Brazil measu.....»»
Isotope analysis reveals mammoth as key food source for ancient Americans
Scientists have uncovered the first direct evidence that ancient Americans relied primarily on mammoth and other large animals for food. Their research sheds new light on both the rapid expansion of humans throughout the Americas and the extinction o.....»»
Scientists streamline creation of nucleoside analogs, a group of life-saving molecules
A team of researchers has found a quicker and more efficient way to create nucleoside analogs, a type of small molecule that can be used in treatments for everything from cancer to viral diseases......»»
Liquid water molecules are inherently asymmetric: New insight into the bonds between water molecules
Icebergs float on water because the underlying liquid water has a higher density than the iceberg. Liquid water itself has its highest density at 4°C—one of the so-called anomalies of water, i.e. properties of liquids that are rarely observed for.....»»
Webb finds new galaxies in Spiderweb protocluster field
Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers have found new galaxies in the Spiderweb protocluster. Their characteristics shed light on the growth of galaxies in these large cosmic cities, with the finding t.....»»
Discovery of molecular switch explains how bacteria control their protein biosynthesis through cell metabolism
Protein biosynthesis—the process whereby cells produce protein molecules, which are essential for life and growth—is a highly complex and strictly regulated affair. An interdisciplinary team led by LMU biologist PD Dr. Jürgen Lassak has now disc.....»»
Where to watch the 2024 Christmas Tree Lighting at Rockefeller Center
The country's most iconic Christmas tree will light up the New York City sky. Find out how to watch the 2024 Christmas Tree Lighting at Rockefeller Center......»»
New study sheds light on when to stand out or fit in
When it comes to job interviews, conventional wisdom often suggests that standing out is key to securing a position—seemingly at odds with the general human tendency to conform. A new study by SFI Complexity Postdoctoral Fellow Katrin Schmelz and h.....»»
