The formation of switchable and metastable discrete structures through chiral self-sorting
A paper titled "Thermo-/Mechano-Chromic Chiral Coordination Dimer: Formation of Switchable and Metastable Discrete Structure through Chiral Self-Sorting" describes chiral coordination dimers that emerge based on effectively exclusive chiral self-sort.....»»
Treasures beneath the ocean floor? Seawater plays role in gold formation
Understanding how gold forms is crucial for knowing where to find it and how to extract it sustainably. McGill researchers have answered a long-standing question in geology that could lead to new ore discoveries......»»
Physicists explore how fluctuations shape transport networks
Understanding how transport networks, such as river systems, form and evolve is crucial to optimizing their stability and resilience. It turns out that networks are not all alike. Tree-like structures are adequate for transport, while networks contai.....»»
A review of progress and outlook for photodetectors based on graphene–semiconductor hybrid structures
A recent review summarizes the progress made in graphene-semiconductor hybrid photodetectors over the past decade. It begins by introducing key photodetector performance indicators, providing the basis for an accurate performance evaluation. The revi.....»»
New vestiges of the first life on Earth discovered in Saudi Arabia
Stromatolites are the earliest geological record of life on Earth. These curious biotic structures are made of algae carpets growing toward the light and precipitating carbonates. After their first appearance 3.48 Ga ago, stromatolites dominated the.....»»
Simulations demonstrate potential mechanisms of intermediate-mass black hole formation in globular clusters
Joint research led by Michiko Fujii of the University of Tokyo demonstrates a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed st.....»»
AIM algorithm enhances super-resolution microscope images in real time
When trying to measure molecular structures with nanometer precision, every bit of noise shows up in the data: someone walking past the microscope, tiny vibrations in the building and even the traffic outside. A new processing technique removes noise.....»»
OpenAI training its next major AI model, forms new safety committee
GPT-5 might be farther off than we thought, but OpenAI wants to make sure it is safe. Enlarge (credit: Getty Images) On Monday, OpenAI announced the formation of a new "Safety and Security Committee" to oversee risk mana.....»»
Dyson spheres: Astronomers report potential candidates for alien structures, and evidence against their existence
There are three ways to look for evidence of alien technological civilizations. One is to look out for deliberate attempts by them to communicate their existence, for example, through radio broadcasts. Another is to look for evidence of them visiting.....»»
Daily Telescope: The initial results from Europe’s Euclid telescope are dazzling

Scientists develop technique to analyze RNA structures in ultra-high definition
Scientists at the University of Nottingham have developed a technique to analyze the atomic-level structure of RNA molecules with exceptional precision and speed, and are the first in the world to use the method to examine structural changes in RNA w.....»»
Birth of universe"s earliest galaxies observed for first time
Using the James Webb Space Telescope, University of Copenhagen researchers have become the first to see the formation of three of the earliest galaxies in the universe, more than 13 billion years ago. The sensational discovery contributes important k.....»»
Study sheds light on how antibiotic "Velcro" kills bacteria
A small antibiotic called plectasin uses an innovative mechanism to kill bacteria. By assembling into large structures, plectasin latches onto its target on the bacterial cell surface, similar to how both sides of Velcro form a bond......»»
Previously unknown dormouse habitat identified
Bayreuth researchers have shown for the first time that the dormouse, which is strictly protected in Germany, not only uses woody structures as a habitat, but also reed beds. The study is published in the Journal of Vertebrate Biology......»»
Research team uncovers mechanism for spikelet development in barley
The inflorescence architecture of crop plants like barley is predominantly regulated by meristem activity and fate, which play a critical role in determining the number of floral structures for grain production......»»
Green infrastructure plans need to consider historical racial inequalities, say researchers
Urban planners increasingly are interested in green infrastructure projects for the health and climate benefits they bring to cities. But without attention to historical development patterns and existing power structures, such projects may not benefi.....»»
Researchers introduce programmable materials to help heal broken bones
Natural materials like bone, bird feathers and wood have an intelligent approach to physical stress distribution, despite their irregular architectures. However, the relationship between stress modulation and their structures has remained elusive......»»
What happened to OpenAI’s long-term AI risk team?
Former team members have either resigned or been absorbed into other research groups. Enlarge (credit: Benj Edwards) In July last year, OpenAI announced the formation of a new research team that would prepare for the adv.....»»
Into the abyss: Understanding black hole formation through natal kicks and neutrino emission
A new study in Physical Review Letters explores the conditions of black hole formation from dying stars, particularly the role of neutrino-induced natal kicks in the formation process......»»
Quantum geometry offers new insights into "smart" materials with switchable electric polarity
