Scientists have long held that electricity is carried by individual electrons with discrete charges moving in a metal, even in the case of electrons clumped into quasiparticles. However, 鈥渟trange metals鈥� fail to obey this paradigm. Researchers have observed a radical quantum blurring of electrons in strange metal into a featureless liquid, potentially pointing toward a new theory of electrical transport.
From laundry detergent to dishwasher tablets, cleaning products are an indispensable part of life. Yet the chemicals that make these products so effective can be difficult to break down or could even trigger ecosystem-altering algal blooms.
As of early 2025, tuberculosis cases are increasing in the U.S. This disease, often shortened to TB, causes significant lung damage and, if not treated, is almost always lethal. World TB Day on March 24 raises awareness about the disease and commemorates Robert Koch鈥檚 discovery of the source bacterium Mycobacterium tuberculosis. More than a century later, scientists continue refining TB diagnosis methods and treatment strategies , some of which are in these four ACS journal articles.
If you鈥檝e ever noticed how memories from the same day seem connected while events from weeks apart feel separate, a new study reveals the reason: Our brains physically link memories that occur close in time not in the cell bodies of neurons, but rather in their spiny extensions called dendrites.
In a groundbreaking study on the synthesis of cellulose 鈥� a major constituent of all plant cell walls 鈥� a team of Rutgers University-New Brunswick researchers has captured images of the microscopic process of cell-wall building continuously over 24 hours with living plant cells, providing critical insights that may lead to the development of more robust plants for increased food and lower-cost biofuels production.
Energy-hungry Artificial Intelligence 鈥榟as an unsustainable impact in terms of CO2 emissions; training large deep learning models (such as GPT and BERT) has a significant environmental impact, in fact training a model such as GPT-3 (175 billion parameters) required 355 GPU-years (the GPU is the type of processor used for AI), costing an estimated $4.6 million in energy alone and consuming around 1300 megawatt-hours (MWh) for training alone, equivalent to the annual consumption of 130 homes in the US.
Researchers develop Symbolic Modeling鈥攁n AI-powered technique creating unified mathematical models for financial asset pricing. Compared to neural network, the generated mathematical expression by symbolic modeling is easier to comprehend and analyze. Testing across hundreds of company鈥檚 datasets shows lower prediction errors and reduced unexplainable return compared to classic asset pricing models like CAPM or Fama-French 3-Factor model.
AI, Data Science, and the Transformation of Scientific Research: A Primer
Tiny nematodes, commonly known as vinegar eelworms, can move objects with a force hundreds of times their own weight.
Researchers see hints that dark energy, widely thought to be a 鈥渃osmological constant,鈥� might be evolving over time in unexpected ways.
At WHOI, Motta leads the Theoretical Chemistry and Isotope Biogeochemistry Lab. Her research focuses on advancing our fundamental understanding of chemistry inspired by marine processes that challenge our current chemical knowledge.
Breakthrough in quantum sensing could revolutionise high-precision measurement technologies
鈥淎 professor at the Department of Geology, Faculty of Science, Chulalongkorn University, has discovered evidence of an earthen embankment indicating another large ancient community in the location overlapping the old city of Nakhon Ratchasima.鈥�
Caris Life Sciences庐 (Caris), a leading next-generation AI TechBio company and precision medicine pioneer, today announced the publication of "Real-world evidence provides clinical insights into tissue-agnostic therapeutic approvals" in Nature Communications.
A pioneering study has introduced an innovative framework to evaluate global inequalities in Particulate Matte (PM2.5) exposure and ecological possession, shedding light on the growing environmental disparities across nations.
Atomic nuclei with 鈥渕agic numbers鈥� of protons or neutrons in their nuclear shells are extremely stable. Nuclear physicists are especially interested in nuclei with doubly magic numbers鈥攖hose that have full shells for both protons and neutrons. One example is the tin isotope Sn-100, which has 50 protons and 50 neutrons. To prepare for future work on Sn-100, researchers studied the properties of isotopes of indium as they approached 50 neutrons. This helps to demonstrate how adding single particles changes the properties of a nucleus.
Cornell College Assistant Professor of Statistics Tyler George and one of his classes took part in a newly published study exploring how a unique computer game created a research experience that engaged students.
3D modeling shows how larger brains triggered changes in jaw muscles and joint mechanics that powered a flexible feeding system for modern birds.
A groundbreaking new study using the Dark Energy Survey (DES) final datasets suggests potential inconsistencies in the standard cosmological model, known as 螞CDM. If confirmed, these findings could fundamentally alter our understanding of the Universe. DES was conducted using the 570-megapixel Department of Energy-fabricated Dark Energy Camera (DECam), mounted on the U.S. National Science Foundation V铆ctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF NOIRLab.
The DESI collaboration has published a new analysis of dark energy using their first three years of collected data, which spans nearly 15 million galaxies and quasars. Combined with studies of the cosmic microwave background, supernovae, and weak lensing, the analysis hints that dark energy changes over time. Data Release 1, containing data from DESI鈥檚 survey validation and first year of observations, has now been made available for scientists and the public to explore.
