Reverse-engineering the division microcode in the Intel 8086 processor

“While programmers today take division for granted, most microprocessors in the 1970s could only add and subtract — division required a slow and tedious loop implemented in assembly code. One of the nice features of the Intel 8086 processor (1978) was …

RP2040 with PIO and DMA to address WS2812B LEDs

“I love the WS2812B (aka SK6812) addressable LEDs: they are inexpensive and available in different packages. I have used them in different projects, including the MetaClockClock one. I used the NXP Kinetis for these projects, but because they are not …

Second stage for quantum simulation project PASQuanS

“The EU flagship project PASQuanS2 with 25 partners coordinated by Immanuel Bloch, Director at MPQ and Chair at LMU, is funded by the European Union. Quantum technologies are on the rise. One promising area is the simulation of quantum many-body …

Stripes within crystals hint at behavior of electrons in quantum systems

“A hidden pattern of electrons could provide clues to exotic quantum behavior Hidden stripes in a crystal could help scientists understand the mysterious behavior of electrons in certain quantum systems, including high-temperature superconductors, an unexpected discovery by RIKEN physicists suggests1 …

The Juice Mission: Japan Joins Esa To Head To The Icy Moons

“This month, the JUpiter ICy moon Explorer (JUICE) is set to embark on an eight year journey to the icy moons of our Solar System’s largest planet. While the moons have been previously observed by Jupiter explorers such as …

Tiny biobattery with 100-year shelf life runs on bacteria

“Watson College Professor Seokheun “Sean” Choi aims to make fuel cells for portable, storable and on-demand power generation. Last fall, Professor Seokheun “Sean” Choi and his Bioelectronics and Microsystems Laboratory published their research into an ingestible biobattery activated by the …

Wonder material graphene claims yet another superlative

“In a paper published in Nature this week (13 Apr 2023), researchers from The University of Manchester report record-high magnetoresistance that appears in graphene under ambient conditions. Materials that strongly change their resistivity under magnetic fields are highly sought for …

A four-legged robotic system for playing soccer on various terrains

““DribbleBot” can maneuver a soccer ball on landscapes such as sand, gravel, mud, and snow, using reinforcement learning to adapt to varying ball dynamics. If you’ve ever played soccer with a robot, it’s a familiar feeling. Sun glistens …

A new type of photonic time crystal gives light a boost

“The researchers created photonic time crystals that operate at microwave frequencies, and they showed that the crystals can amplify electromagnetic waves. Researchers have developed a way to create photonic time crystals and shown that these bizarre, artificial materials amplify the …
