Supernova Surprise Creates Elemental Mystery – Most Important Reaction in the Universe Can Get a Huge and Unexpected Boost
Posted by Genevieve Klien in categories: computing, cosmology
Michigan State University researchers have discovered that one of the most important reactions in the universe can get a huge and unexpected boost inside exploding stars known as supernovae.
This finding also challenges ideas behind how some of the Earth’s heavy elements are made. In particular, it upends a theory explaining the planet’s unusually high amounts of some forms, or isotopes, of the elements ruthenium and molybdenum.
“It’s surprising,” said Luke Roberts, an assistant professor at the Facility for Rare Isotope Beams and the Department of Physics and Astronomy, at MSU. Roberts implemented the computer code that the team used to model the environment inside a supernova. “We certainly spent a lot of time making sure the results were correct.”

The exact gene that caused stem cell aging has been identified.
Above – When mesenchymal stem/stromal cells (MSCs) age, the transcription factor GATA6 is increasingly produced in the cell to induce aging response. By transcription factor-based cellular reprogramming, aged MSCs are rejuvenated with a reduction in GATA6 effects on cellular aging. CREDIT AlphaMed Press

Emerging wearable technology uses tiny fibers that can track your blood pressure, heart rate, and more
Posted by Jeff Myers in categories: biotech/medical, wearables
A shirt that monitors your blood pressure or a pair of socks that can keep track of your cholesterol levels might be just a few years away from becoming reality.
In an article published in Applied Physics Reviews, researchers examine the use of microfibers, and even smaller nanofibers, as wearable monitors that could keep track of a patient’s vital signs.
The microfiber- and nanofiber-based technology addresses growing concerns in the medical community about monitoring chronic illnesses like diabetes, asthma, obesity, and high blood pressure as the population ages.

The Real Spider Man — Alex Greenhalgh, CEO, Spintex — Novel And Powerful Bio-Materials and Fabrics
Posted by Ira S. Pastor in categories: biotech/medical, materials
Spider silk is a protein fiber spun by spiders, which they use to make webs or other structures, which function as sticky nets to catch other animals, or as nests or cocoons to protect their offspring, or to wrap up prey. They can also use their silk to suspend themselves, to float through the air, or to glide away from predators.
Each spider and each type of silk has a set of mechanical properties optimized for their biological function, but in particular, their dragline silks, have exceptional mechanical properties. They exhibit a unique combination of high tensile strength and extensibility which enables a silk fiber to absorb a large amount of energy before breaking with this estimated tensile strength several times that of steel.

Bees Witnessed Using Tools in Nature For The First Time… And It’s Really Gross
Posted by Raphael Ramos in category: futurism
The Asian honeybee (Apis cerana) isn’t just on the look-out for flowers. In some areas, it’s also on the prowl for poo.
When threatened by a species of giant hornet (Vespa soror) — closely related to the murder hornet — workers will fly off to collect fresh animal faeces to smear carefully around the entrance of their nest, according to a study on bee hives in Vietnam.
It’s still not clear how this dung actually protects the colony, but in the field, it appears to stop scouting hornets from chewing through the nest and causing mass slaughter.
