Advances in theoretical modeling of atomic nuclei
The atomic nucleus is a tough nut to crack. The strong interaction between the protons and neutrons that make it up depends on many quantities, and these particles, collectively known as nucleons, are subject to not only two-body forces but also thre.....»»
It"s hearty, it"s meaty, it"s mold: Hacking the genome of fungi for smart foods of the future
With animal-free dairy products and convincing vegetarian meat substitutes already on the market, it's easy to see how biotechnology can change the food industry. Advances in genetic engineering are allowing us to harness microorganisms to produce cr.....»»
High-resolution imagery advances the ability to monitor decadal changes in emperor penguin populations
Emperor penguin populations have been exceedingly difficult to monitor because of their remote locations and because individuals form breeding colonies on seasonal sea ice fastened to land (known as fast ice) during the dark and cold Antarctic winter.....»»
AI for astrophysics: Algorithms help chart the origins of heavy elements
The origin of heavy elements in our universe is theorized to be the result of neutron star collisions, which produce conditions hot and dense enough for free neutrons to merge with atomic nuclei and form new elements in a split-second window of time......»»
Paper offers a mathematical approach to modeling a random walker moving across a random landscape
Tiny particles like pollen grains move constantly, pushed and pulled by environmental forces. To study this motion, physicists use a "random walk" model—a system in which every step is determined by a random process. Random walks are useful for stu.....»»
A coral superhighway in the Indian Ocean
New research has revealed that, despite being scattered across more than a million square kilometers, remote coral reefs across the Seychelles are closely related. Using genetic analyses and oceanographic modeling, researchers at Oxford University ha.....»»
How advances in AI are impacting business cybersecurity
While ChatGPT and Bard have proven to be valuable tools for developers, marketers, and consumers, they also carry the risk of unintentionally exposing sensitive and confidential data. From a security point of view, it always pays to think one step ah.....»»
Enhancing identifiability in plant growth models: A comprehensive framework for precision and reliability
In the evolving landscape of plant growth modeling, there is a distinguished presence of mechanistic models aimed at capturing the intricate dynamics of plant development through parameter estimation from experimental data. However, these models face.....»»
Root phenotyping research: Automated total root length estimation from in situ images without segmentation
Climate change stresses severely limit crop yields, with root traits playing a vital role in stress tolerance, thus highlighting the importance of root phenotyping for crop improvement. Recent advances in image-based root phenotyping, particularly th.....»»
Statisticians and physicists team up to bring a machine learning approach to mining of nuclear data
Physicists use theoretical models to study physical quantities, such as the mass of nuclei, where they do not have experimental data. However, using a single imperfect theoretical model can lead to misleading results. To improve the quality of extrap.....»»
Harnessing the mechanisms of fungal bioluminescence to confer autonomous luminescence in plant and animal cells
In a striking new study published in Science Advances, a team of synthetic biologists led by Karen Sarkisyan at the MRC Laboratory of Medical Sciences, have reported the discovery of multiple plant enzymes—hispidin synthases—that can perform the.....»»
Sharks, turtles and other sea creatures face greater risk from industrial fishing than previously thought
My colleagues and I mapped activity in the northeast Pacific of "dark" fishing vessels—boats that turn off their location devices or lose signal for technical reasons. In our new study published in Science Advances, we found that highly mobile mari.....»»
Scientists develop new machine learning method for modeling chemical reactions
Researchers from Carnegie Mellon University and Los Alamos National Laboratory have used machine learning to create a model that can simulate reactive processes in a diverse set of organic materials and conditions......»»

Genetic mutation in a quarter of all Labradors hard-wires them for obesity
New research finds around a quarter of Labrador retriever dogs face a double-whammy of feeling hungry all the time and burning fewer calories due to a genetic mutation. The results are published in the journal Science Advances......»»
Team successfully synthesizes atomically precise metal nanoclusters
A research team has successfully synthesized a metal nanocluster and determined its crystal structure. Their study provides experimental evidence for understanding and designing nanoclusters with specific properties at the atomic level. Metal nanoclu.....»»
We know the Arctic is warming—what will changing river flows do to its environment?
Scientists at the University of Massachusetts Amherst recently combined satellite data, field observations, and sophisticated numerical modeling to paint a picture of how 22.45 million square kilometers of the Arctic will change over the next 80 year.....»»
Modeling the origins of life: New evidence for an "RNA World"
Charles Darwin described evolution as "descent with modification." Genetic information in the form of DNA sequences is copied and passed down from one generation to the next. But this process must also be somewhat flexible, allowing slight variations.....»»
Resonant tunneling: A possible way to probe the minimum length using atomic systems
A research team led by Prof. Dr. Yang Yong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has revealed a remarkable quantum tunneling phenomenon across double potential barriers. They found that quantum tunneling is.....»»
Scientists reveal how light behaves in formless solids
For a long time, it was thought that amorphous solids do not selectively absorb light because of their disordered atomic structure. However, a new uOttawa study disproves this theory and shows that amorphous solids actually exhibit dichroism, meaning.....»»
AI technique "decodes" microscope images, overcoming fundamental limit
Atomic force microscopy, or AFM, is a widely used technique that can quantitatively map material surfaces in three dimensions, but its accuracy is limited by the size of the microscope's probe. A new AI technique overcomes this limitation and allows.....»»
