Researchers define protocol for high-resolution imaging of living cells using atomic force microscopy
Images of nanoscale structures inside living cells are in increasing demand for the insights into cellular structure and function that they can reveal. So far, the tools for capturing such images have been limited, but researchers led by Takeshi Fuku.....»»
Next major X-ray mission set to launch
The X-Ray Imaging and Spectroscopy Mission (XRISM) is ready to launch on 7 September 2023 to observe the most energetic objects and events in the cosmos. In doing so, it will unveil the evolution of the universe and the structure of spacetime......»»

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 incoming adenoviruses change their chromatin structure for efficient gene expression
Adenoviruses, known for their low pathogenicity and technological approachability, have become instrumental in many therapeutic applications, including as a vaccination vector platform during the recent SARS-CoV-2 pandemic. Central to their efficacy.....»»
Exploring light neutron-rich nuclei: First observation of oxygen-28
The study of physical systems under extreme conditions offers valuable insights into their organization and structure. In nuclear physics, neutron-rich isotopes, especially the light ones with neutron-to-proton ratio significantly different from that.....»»
Study finds how some ion channels form structures permitting drug delivery
A member of an important class of ion channel proteins can transiently rearrange itself into a larger structure with dramatically altered properties, according to a study led by researchers at Weill Cornell Medicine. The discovery is a significant ad.....»»
Double barrier design proposed to enhance tunneling electroresistance
Based on density functional theory analysis, a research team led by Prof. Zheng Xiaohong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences proposed that the double barrier structure can greatly enhance the tunneling ele.....»»
Optimizing molecular photoswitches for solar energy harvesting
Molecular photoswitches that can both convert and store energy could be used to make solar energy harvesting more efficient. A team of researchers has used a quantum computing method to find a particularly efficient molecular structure for this purpo.....»»
India"s moon rover confirms sulfur and detects several other elements near the lunar south pole
India's moon rover confirmed the presence of sulfur and detected several other elements near the lunar south pole as it searches for signs of frozen water nearly a week after its historic moon landing, India's space agency said Tuesday......»»
Northern map turtles found to survive cold winter conditions by staying active under ice
Imagine it's winter, and you're standing on a frozen lake or pond, when suddenly below your feet you notice hundreds of turtles. What are they doing down there below the ice?.....»»
Surprise! Ötzi the Iceman was bald and had darker skin than presumed
Ötzi’s ancestors were early Anatolian farmers, not Steppe Herders as previously believed. Enlarge / Study reveals that compared to other contemporary Europeans, Ötzi’s genome had an unusually high proportion of genes in com.....»»
The "weird" male Y chromosome has finally been fully sequenced. Can we now understand how it works, how it evolved?
The Y chromosome is a never-ending source of fascination (particularly to men) because it bears genes that determine maleness and make sperm. It's also small and seriously weird; it carries few genes and is full of junk DNA that makes it horrendous t.....»»
Sweet corn yield at the mercy of the environment, except for one key factor
A new analysis from the University of Illinois Urbana-Champaign and the USDA-Agricultural Research Service (ARS) has identified the top factors accounting for yield variability in processing sweet corn (used for canned and frozen products), including.....»»
CNN+ is back from the dead as CNN Max debuts Sept. 27
CNN Max isn't quite what CNN+ was supposed to be before it was killed off in 2022, but it's built on much of the same structure......»»
Scientists reveal how color-changing fish know when they are the perfect shade
When fish suddenly change color, there are little photoreceptors embedded deep within their skin keeping watch to ensure the color is just right, according to new research......»»
Study finds evidence of the formation and structural evolution of prehistoric agricultural economy in Central China
A research team led by Prof. Yang Yuzhang from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) investigated the human subsistence strategy evolution of agricultural structure during the Yangshao cultu.....»»
Antarctica has never needed our help more, says researcher who has spent 40 years studying the frozen continent
After decades immersed in Antarctic science, I've learned that physical and biological changes rarely occur smoothly. More often than not, they unfold in sharp steps. Right now, Antarctica's climate and ecosystems are experiencing disturbing changes......»»
Bronze Age family systems deciphered: Paleogeneticists analyze 3,800-year-old extended family
