Whether you’re an advanced player able to describe the exact sound you’re after or a beginner who can only name the song whose tone they crave, REACTOR is fit to serve and near destined to impress. The post Positive Grid REACTOR Intelligent Guitar Amplifier review: Perfect for practice, set for the stage appeared first on Popular Science.

Glasses are non-crystalline but solid states of matter in which molecules and atoms are not arranged into a regular crystal lattice, but rather in a disordered pattern. Glassy materials are widely used in various settings, for instance, in the synthesis of pharmaceuticals and the development of electronics or optical devices.

Astronomers have finally cracked the mystery behind a strange class of repeating cosmic signals that has baffled scientists for years. Using Australia’s ASKAP radio telescope, researchers traced the bursts to a rare stellar duo in which a dense white dwarf is relentlessly siphoning material from a nearby red dwarf companion. As the stolen matter spirals inward, the system unleashes powerful radio waves and X-rays every 1.4 hours.

A team of astronomers has found the strongest evidence yet that some planets outside our solar system may be magnetic. Using the European Southern Observatory's Very Large Telescope (ESO's VLT) and the Gemini North telescope, the researchers measured wind speeds on seven very hot, Jupiter-like exoplanets.

A breakthrough hydrogen-production method could make clean fuel far cheaper and easier to generate. Researchers at the University of Birmingham developed a perovskite-based catalyst that splits water into hydrogen at much lower temperatures than existing technologies, potentially allowing factories, steel plants, cement works, and renewable energy sites to turn waste heat into valuable hydrogen.

Scientists have created a tiny chip that can generate, steer, and read light-based information all in one device, marking a major leap toward ultra-fast, energy-efficient computing. The breakthrough uses atomically thin materials and nanoscale structures to control a unique quantum property of light called the “valley” degree of freedom, allowing information to be encoded in new ways.

Plastics, medicines, cosmetics—there are very few everyday products that do not rely on using fossil resources. A European research team led by Charité—Universitätsmedizin Berlin is now aiming to revolutionize this cornerstone of the chemical industry: as part of the CarboNcare project, scientists are developing bacteria that can produce important chemical base materials from sustainable methanol—thereby replacing fossil resources.

Climate change and sea level rise are altering the chemistry of Biscayne Bay in ways that could threaten South Florida's coastal ecosystems, water resources, fisheries, and recreation, according to a study led by scientists from the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science and Miami-Dade County's Department of Environmental Resources Management. Researchers found that over the past 20 years, Biscayne Bay has become warmer, saltier, and more acidic.

Researchers have developed a urine-based screening tool that may help identify individuals who are most likely to be diagnosed with autism later in life, opening the door to assessment and support networks.Continue ReadingCategory: ADHD & Autism, Brain Health, Body and MindTags: Arizona State University, Diagnostic devices, Autism spectrum disorder, Developmental conditions, Brain, Neuroscience
