Tanks of the Triassic: New crocodile ancestor identified
Dinosaurs get all the glory. But aetosaurs, a heavily armored cousin of modern crocodiles, ruled the world before dinosaurs did. These tanks of the Triassic came in a variety of shapes and sizes before going extinct around 200 million years ago. Today, their fossils are found on every continent except Antarctica and Australia.  03/18/2024 04:45 PM

Backyard insect inspires invisibility devices, next gen tech
Leafhoppers, a common backyard insect, secrete and coat themselves in tiny mysterious particles that could provide both the inspiration and the instructions for next-generation technology, according to a new study. In a first, the team precisely replicated the complex geometry of these particles, called brochosomes, and elucidated a better understanding of how they absorb both visible and ultraviolet light.  03/18/2024 04:45 PM

Two artificial intelligences talk to each other
Performing a new task based solely on verbal or written instructions, and then describing it to others so that they can reproduce it, is a cornerstone of human communication that still resists artificial intelligence (AI). A team has succeeded in modelling an artificial neural network capable of this cognitive prowess. After learning and performing a series of basic tasks, this AI was able to provide a linguistic description of them to a 'sister' AI, which in turn performed them.  03/18/2024 02:24 PM

Holographic message encoded in simple plastic
Important data can be stored and concealed quite easily in ordinary plastic using 3D printers and terahertz radiation, scientists show. Holography can be done quite easily: A 3D printer can be used to produce a panel from normal plastic in which a QR code can be stored, for example. The message is read using terahertz rays -- electromagnetic radiation that is invisible to the human eye.  03/18/2024 02:23 PM

Breathe, don't vent: Turning down the heat is key to managing anger
Venting about a source of anger might feel good in the moment, but it's not effective at reducing the rage, new research suggests. Instead, techniques often used to address stress -- deep breathing, mindfulness, meditation, yoga or even counting to 10 -- have been shown to be more effective at decreasing anger and aggression.  03/18/2024 02:23 PM

Feeling apathetic? There may be hope
A new method that aims to help people develop grit looks promising.  03/18/2024 02:23 PM

Self-heating concrete is one step closer to putting snow shovels and salt out of business
Researchers recently reported on the science behind its special concrete, that can warm itself up when it snows, or as temperatures approach freezing.  03/18/2024 02:22 PM

Speaking without vocal cords, thanks to a new AI-assisted wearable device
Bioengineers have invented a thin, flexible device that adheres to the neck and translates the muscle movements of the larynx into audible speech. The device is trained through machine learning to recognize which muscle movements correspond to which words. The self-powered technology could serve as a non-invasive tool for people who have lost the ability to speak due to vocal cord problems.  03/15/2024 04:10 PM

Fatty food before surgery may impair memory in old, young adults
Eating fatty food in the days leading up to surgery may prompt a heightened inflammatory response in the brain that interferes for weeks with memory-related cognitive function in older adults -- and, new research in animals suggests, even in young adults.  03/15/2024 04:10 PM

Oregon State researchers take deep dive into how much water is stored in snow
There's a new metric that provides a more holistic look at how much water is stored in snowpack, and for how long.  03/15/2024 04:10 PM

'Noisy' roundworm brains give rise to individuality
Research has demonstrated individual differences in and successfully extracted commonalities from the whole-brain activity of roundworms. The researchers also found that computer simulations based on the whole-brain activity of roundworms more accurately reflect real-brain activity when they include so-called 'noise,' or probabilistic elements.  03/15/2024 04:10 PM

Gut bacteria make neurotransmitters to shape the newborn immune system
Investigators discovered that unique bacteria colonize the gut shortly after birth and make the neurotransmitter serotonin to educate gut immune cells. This prevents allergic reactions to food and the bacteria themselves during early development.  03/15/2024 04:10 PM

Why killer T cells lose energy inside of solid tumors
Researchers have discovered the reason why immune cells lose energy when they enter the solid tumor microenvironment -- and how to restore their energy levels. A metabolic enzyme, called Acetyl-CoA carboxylase, has been identified as the culprit, for it causes T cells to store fat, rather than burning fat for energy.  03/15/2024 04:10 PM

Even inactive smokers are densely colonized by microbial communities
Everything is everywhere -- under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team is presently working to accurately quantify how much inorganic carbon can be bound in these environments.  03/15/2024 04:09 PM

Meteorology: Weak polar vortex makes weather more predictable
Events in the stratosphere are making long-range weather in Northern Europe easier to forecast, researchers have discovered.  03/15/2024 04:09 PM

Breakthrough in ultraviolet spectroscopy
Physicists achieve major leap in precision and accuracy at extremely low light levels.  03/15/2024 04:09 PM

Arctic nightlife: Seabird colony bursts with sound at night
Acoustic recordings of a colony of little auks reveal their nocturnal activities and offer valuable monitoring means for avian biology in the Arctic.  03/15/2024 04:09 PM

Revolutionary method developed for mass-producing polymer solid electrolytes
Scientists have unveiled a groundbreaking technique for mass-producing polymer solid electrolytes, crucial components in batteries.  03/15/2024 04:09 PM

New research suggests that our universe has no dark matter
A new study challenges the current model of the universe by showing that, in fact, it has no room for dark matter.  03/15/2024 04:09 PM

Protein fragments ID two new 'extremophile' microbes--and may help find alien life
Perfectly adapted microorganisms live in extreme environments from deep-sea trenches to mountaintops. Learning more about how these extremophiles survive in hostile conditions could inform scientists about life on Earth and potential life on other planets.  03/15/2024 04:09 PM
