Tanks of the Triassic: New crocodile ancestor identified
- ScienceDaily
- 24/3/18 21:45
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.
Backyard insect inspires invisibility devices, next gen tech
- ScienceDaily
- 24/3/18 21:45
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...
Two artificial intelligences talk to each other
- ScienceDaily
- 24/3/18 19:24
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...
Holographic message encoded in simple plastic
- ScienceDaily
- 24/3/18 19:23
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.
Breathe, don't vent: Turning down the heat is key to managing anger
- ScienceDaily
- 24/3/18 19:23
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.

Why killer T cells lose energy inside of solid tumors
- ScienceDaily
- 24/3/15 21:10
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.
Even inactive smokers are densely colonized by microbial communities

Study of long-term student engagement challenges 'one great teacher' narrative of education
- ScienceDaily
- 24/3/15 01:07
A positive relationship with a teacher at an early age may help children to feel more engaged with school, but not necessarily in the long term, new research shows. A new study of more than 3,600 young people in Australia shows that their 'school engagement' -- their interest in school and willingness to learn -- fluctuates between ages eight and 15, especially during the transition between...
