LEVITATING BANANA - Electromagnetic Levitation

“I shall be demonstrating how to levitate a banana. Your first thought would be, “Why?”. How often do you see objects floating in thin air, and how often do you see a banana floating in thin air? Being able to …

Machine-learning models, guided by physics, will improve subsurface imaging

“Potential applications include energy exploration and earthquake early warning, among others A team of scientists at Los Alamos National Laboratory is applying machine-learning algorithms to subsurface imaging that will impact a variety of applications, including energy exploration, carbon capture and …

Microscopy Images Could Lead to New Ways to Control Excitons for Quantum Computing

“For the first time, scientists observe exciton quasiparticles confined in atomically thin materials, opening new paths to controlling excitons for quantum and optolectronic applications Excitons are drawing attention as possible quantum bits (qubits) in tomorrow’s quantum computers and are …

NASA’s Curiosity Finds Surprise Clues to Mars’ Watery Past

“Among other discoveries made by the rover, rippled rock textures suggest lakes existed in a region of ancient Mars that scientists expected to be drier. When NASA’s Curiosity rover arrived at the “sulfate-bearing unit” last fall, scientists thought they …

NASA’s NuSTAR Telescope Reveals Hidden Light Shows on the Sun

“Some of the hottest spots in the Sun’s atmosphere appear in the telescope’s X-ray view. Even on a sunny day, human eyes can’t see all the light our nearest star gives off. A new image displays some …

New polymers could enable better wearable devices

“MIT engineers developed organic polymers that can efficiently convert signals from biological tissue into the electronic signals used in transistors. Certain electronics that integrate with the human body — a smartwatch that samples your sweat, for instance — work by converting the …

New Sodium, Aluminum Battery Aims to Integrate Renewables for Grid Resiliency

“A new battery design could help ease integration of renewable energy into the nation’s electrical grid at lower cost, using Earth-abundant metals, according to a study just published in Energy Storage Materials. A research team, led by the Department …

NodeMCU, ESP8266 and ESP32 Spy Microphone Arduino code

“Here is another update for the “ESP Spy Microphone” project which is ESP8266/NodeMCU and ESP32 WiFi microphone arduino source code, revision 1.5. In this update I have increased the audio stream recorder sample rate to 240KHz for both …

Paper Sundial Kits

“A sundial can track the Sun’s movement throughout the day and year, turning it into a clock, compass, and calendar. There are many types of sundials from relatively simple ones to ones that are quite complex. My intent is …

Princeton scientists measure quantum correlations between molecules for the first time

“Physicists are increasingly using ultracold molecules to study quantum states of matter. Many researchers contend that molecules have advantages over other alternatives, such as trapped ions, atoms or photons. These advantages suggest that molecular systems will play important roles in …
