Children learn a huge number of words in the early preschool years. A two-year-old might be able to say just a handful of words, while a five-year-old is quite likely to know many thousands. How do children achieve this marvelous feat? The question has occupied psychologists for over a century: In countless carefully designed experiments, researchers titrate the information … [Read more...] about How children integrate information

Additive manufacturing has the potential to allow one to create parts or products on demand in manufacturing, automotive engineering, and even in outer space. However, it's a challenge to know in advance how a 3D printed object will perform, now and in the future. Physical experiments -- especially for metal additive manufacturing (AM) -- are slow and costly. Even modeling … [Read more...] about Using AI to predict 3D printing processes: Engineers use Frontera supercomputer to develop physics-informed neural networks for additive manufacturing

What if a microscope allowed us to explore the 3D microcosm of blood vessels, nerves, and cancer cells instantaneously in virtual reality? What if it could provide views from multiple directions in real time without physically moving the specimen and worked up to 100 times faster than current technology? UT Southwestern scientists collaborated with colleagues in England and … [Read more...] about Novel microscopy method provides look into future of cell biology

Researchers from Brown University and MIT have developed a new data science framework that allows users to process data with the programming language Python -- without paying the "performance tax" normally associated with a user-friendly language. The new framework, called Tuplex, is able to process data queries written in Python up to 90 times faster than industry-standard … [Read more...] about New data science platform speeds up Python queries

Researchers from Tel Aviv University have engineered the world's tiniest technology, with a thickness of only two atoms. According to the researchers, the new technology proposes a way for storing electric information in the thinnest unit known to science, in one of the most stable and inert materials in nature. The allowed quantum-mechanical electron tunneling through the … [Read more...] about Technology only two atoms thick could enable storage of information in thinnest unit

When it comes to understanding and predicting trends in energy use, the internet is a tough nut to crack. So say energy researchers Eric Masanet, of UC Santa Barbara, and Jonathan Koomey, of Koomey Analytics. The two just published a peer-reviewed commentary in the journal Joule discussing the pitfalls that plague estimates of the internet's energy and carbon impacts. The paper … [Read more...] about Common errors in internet energy analysis: Errors can lead well-intentioned studies to predict massive energy growth in IT, which often doesn’t materialize

Electron motion in atoms and molecules is of fundamental importance to many physical, biological, and chemical processes. Exploring electron dynamics within atoms and molecules is essential for understanding and manipulating these phenomena. Pump-probe spectroscopy is the conventional technique. The 1999 Nobel Prize in Chemistry provides a well-known example wherein femtosecond … [Read more...] about Decoding electron dynamics

When it comes to defense, the body relies on attack thanks to the lymphatic and immune systems. The immune system is like the body's own personal police force as it hunts down and eliminates pathogenic villains. "The body's immune system is very good at identifying cells that are acting strangely. These include cells that could develop into tumors or cancer in the future," says … [Read more...] about Machine learning helps in predicting when immunotherapy will be effective

QUT researchers have developed a new machine learning mathematical system that helps to identify and detect changes in biodiversity, including land clearing, when satellite imagery is obstructed by clouds. Using statistical methods to quantify uncertainty, the research, published in Remote Sensing in Ecology and Conservation, analysed available satellite images of an 180km … [Read more...] about New research lifts the clouds on land clearing and biodiversity loss
