A 'spy' in the belly      (via sciencedaily.com)     Original source 

To ensure that wounds remain tightly sealed in the abdomen after surgery, researchers have developed a patch with a sensor function. The polymer patch warns before the occurrence of dangerous leaks on sutures in the gastrointestinal tract take hold, while closes the areas on its own. A new material now enables a fast, easy and non-invasive leak diagnosis.

A 'pinch' of mineral salts helps the noncaloric sweeteners go down      (via sciencedaily.com)     Original source 

Perfect noncaloric replacements for sugar and high fructose corn syrup just don't exist yet. For example, some alternatives have a lingering sweet aftertaste and lack a sugar-like mouthfeel, leaving some consumers unsatisfied. Now, researchers propose adding blends of nutritionally important mineral salts to make noncaloric sweeteners seem more like the real thing. Taste-testers indicated that these blends gave zero- and low-calorie drinks a better flavor.

Video games spark exciting new frontier in neuroscience      (via sciencedaily.com)     Original source 

Researchers have used an algorithm from a video game to gain insights into the behavior of molecules within live brain cells. Researchers used coding tools to build an algorithm that is now used by several labs to gather rich data about brain cell activity. The algorithm was applied to observe molecules clustering together -- which ones, when, where, for how long and how often.

New technique in error-prone quantum computing makes classical computers sweat      (via sciencedaily.com)     Original source 

Today's quantum computers often calculate the wrong answer because of noisy environments that interfere with the quantum entanglement of qubits. IBM Quantum has pioneered a technique that accounts for the noise to achieve reliable results. They tested this error mitigation strategy against supercomputer simulations run by physicists, and for the hardest calculations, the quantum computer bested the supercomputer. This is evidence for the utility of today's noisy quantum computers for performing real-world calculations.

Preserving forests to protect deep soil from warming      (via sciencedaily.com)     Original source 

An innovative, decade-long experiment in the foothills of California's Sierra Nevada mountains shows carbon stocks buried deep underground are vulnerable to climate change. The findings have implications for mitigating global warming through the natural carbon sinks provided by soil and forests which capture 25% of all carbon emissions.

Hotter sand from microplastics could affect sea turtle development      (via sciencedaily.com)     Original source 

New research has found that extreme concentrations of microplastics could increase the temperature of beach sand enough to threaten the development of incubating sea turtles.

Geologists challenge conventional view of Earth's continental history, stability with new study      (via sciencedaily.com)     Original source 

The seemingly stable regions of the Earth's continental plates -- the so-called stable cratons -- have suffered repetitive deformation below their crust since their formation in the remote past, according to new research from the University of Illinois Urbana-Champaign. This hypothesis defies decades of conventional plate tectonics theory and begs to answer why most cratons have remained structurally stable while their underbellies have experienced significant change.

Researchers describe the melting of gold nanoparticles in gold-bearing fluids in the Earth's crust      (via sciencedaily.com)     Original source 

Gold is a precious metal that has always fascinated humans. From Priam's Treasure to the legend of El Dorado, gold --regarded as the noblest of metals-- has been a symbol of splendour and wealth in many civilizations. Historically, gold deposits were known to form when metal was transported dissolved by hot aqueous solution flows --hydrothermal fluids-- until it accumulated in some areas in the Earth's upper crust. The recent discovery of gold nanoparticles in such mineral deposits has brought some doubts on the validity of the classical model.

New model offers a way to speed up drug discovery      (via sciencedaily.com)     Original source 

A model known as ConPLex can predict whether potential drug molecules will interact with specific protein targets, without having to perform the computationally intensive calculation of the molecules' structures. By applying a language model to protein-drug interactions, researchers can quickly screen large libraries of potential drug compounds.

Eddies: Circular currents and their influence on the world's hottest ocean      (via sciencedaily.com)     Original source 

Water from the Pacific Ocean flows into the Indian Ocean via the Indonesia Archipelago thanks to a vast network of currents that act as a conveyor belt, transporting warmth and nutrients. Currents can sometimes form circular motions and these are known as eddies. An international group of researchers has modeled the impacts of eddies on the currents that carry water from the Pacific Ocean to the Indian Ocean.

When water temperatures change, the molecular motors of cephalopods do too      (via sciencedaily.com)     Original source 

Working with live squid hatchlings, scientists find the animals can tune their proteome on the fly in response to changes in ocean temperature via the unique process of RNA recoding. The findings inspire new questions about basic protein function.

A new way to develop drugs without side effects      (via sciencedaily.com)     Original source 

Have you ever wondered how drugs reach their targets and achieve their function within our bodies? If a drug molecule or a ligand is a message, an inbox is typically a receptor in the cell membrane. One such receptor involved in relaying molecular signals is a G protein-coupled receptor (GPCR). About one-third of existing drugs work by controlling the activation of this protein. Researchers now reveal a new way of activating GPCR by triggering shape changes in the intracellular region of the receptor. This new process can help researchers design drugs with fewer or no side effects.

Schrödinger's cat makes better qubits      (via sciencedaily.com)     Original source 

Drawing from Schrodinger's cat thought experiment, scientists have built a 'critical cat code' qubit that uses bosons to store and process information in a way that is more reliable and resistant to errors than previous qubit designs.

Physicists discover an exotic material made of bosons      (via sciencedaily.com)     Original source 

Take a lattice -- a flat section of a grid of uniform cells, like a window screen or a honeycomb -- and lay another, similar lattice above it. But instead of trying to line up the edges or the cells of both lattices, give the top grid a twist so that you can see portions of the lower one through it. This new, third pattern is a moiré, and it's between this type of overlapping arrangement of lattices of tungsten diselenide and tungsten disulfide where physicists found some interesting material behaviors.

Calculation shows why heavy quarks get caught up in the flow      (via sciencedaily.com)     Original source 

Theorists have calculated how quickly a melted soup of quarks and gluons -- the building blocks of protons and neutrons -- transfers its momentum to heavy quarks. The calculation will help explain experimental results showing heavy quarks getting caught up in the flow of matter generated in heavy ion collisions.
