An artificial nervous system for communication between wearable and implantable therapeutics Authors
Bioelectronics have transformed our capacity to monitor and treat diseases; however, a lack of micrometer-scale, energy efficient communication options limit these devices from forming integrated networks that enable full-body, sensor driven, physiological control. Inspired by our nervous system’s ability to transmit information via ionic conduction, we engineered a Smart Wireless Artificial Nervous System (SWANS) that utilizes the body’s own tissue to transmit signals between wearables and implantables. When SWANS emits signals, it generates voltage gradients throughout the body that selectively turn on implanted transistor switches when exceeding their gate threshold voltages. SWANS’ implantable communication components maintain syringe-injectable footprints and 15x greater power efficiencies than Bluetooth and Near Field Communication. In vivo studies in rats demonstrate SWANS’ ability to wirelessly regulate dual hind leg motor control by connecting electronic-skin sensors to implantable neural interfaces via ionic signaling as well as coordinate bioelectronics throughout the epidermal, subcutaneous, intraperitoneal, and gastrointestinal spaces.

Grok answers my questions about what Elon meant when he said Tesla FSD v14 will seem sentient
Questions to inspire discussion.
Advanced Navigation and Obstacle Recognition.
🛣️ Q: How will FSD v14 handle unique driveway features? A: The improved neural net and higher resolution video processing will help FSD v14 better recognize and navigate features like speed bumps and humps, adjusting speed and steering smoothly based on their shape and height.
🚧 Q: What improvements are expected in distinguishing real obstacles? A: Enhanced object detection driven by improved algorithms and higher resolution video inputs will make FSD v14 better at distinguishing real obstacles from false positives like tire marks, avoiding abrupt breaking and overreacting.
Edge case handling and smooth operation.
🧩 Q: How will FSD v14 handle complex edge cases? A: The massive jump in parameter count and better video compression will help the AI better understand edge cases, allowing it to reason that non-threatening objects like a stationary hatch in the road aren’t obstacles, maintaining smooth cruising.
How the brain constructs emotional experiences
Using a powerful combination of AI-driven modelling, advanced brain imaging, and close-to-real-life experimental paradigms, the team was able to uncover a brain signature that precisely measures emotional intensity (arousal) across diverse situations ranging from seeing a loved one to a horror movie. Notably, the team was able to disentangle the conscious emotional experience from the automatic physiological responses such as sweating to heart racing.
Beyond the theoretical implications, this discovery opens new avenues for:
New Trends in Bio hacking What Works and What Doesn’t
Biohacking shouldn’t feel like a full-time job—or a scam. If you’re tired of chasing every shiny new trend without results to show for it, this session is your reset button. We’ll break down what’s worth your effort, what’s just a fad, and how to build a strategy that actually works for you.
Your household gadgets could soon be battery-free — scientists create tiny solar cells that can be powered by indoor light
“Currently, solar cells capturing energy from indoor light are expensive and inefficient. Our specially engineered perovskite indoor solar cells can harvest much more energy than commercial cells and is more durable than other prototypes. It paves the way for electronics powered by the ambient light already present in our lives.”
Perovskite is already becoming a popular material for use in solar panels, with marked benefits compared with silicon-based materials.
X Particles Detected Inside LHC for the First Time Ever!
Physicists at the LHC have recently identified a collection of approximately one hundred “X particles” originating from the early moments of the Big Bang. These findings, which may lead to a deeper understanding of the universe, have been published in the Physical Review Letters journal.
Particle accelerators bring particles into high-speed collisions. The largest of these is the Large Hadron Collider (LHC), located near Geneva. The purpose of these experiments is to simulate aspects of the Big Bang and to examine how matter behaves under those conditions.
In recent years, these high-energy collisions have led to the discovery of several theorized particles. More recently, physicists have detected about a hundred short-lived “X particles,” so named due to their mysterious structures, amid billions of elementary particles.
CT Scans Projected to Result in 100,000 New Cancers Across The US
More Americans are receiving computed tomography (CT) scans than ever before, and while this technology can save lives, some scientists are concerned that low doses of ionizing radiation could increase cancer risk.
Importantly, at an individual level, the theoretical risk of developing cancer from a CT scan is thought to be very low, if it exists at all. Patients should not hesitate to undergo these tests if they are considered medically necessary.
However, the number of CT examinations performed annually in the US has increased by more than 30 percent since 2007, and researchers suggest that unwarranted tests are exposing the population to unnecessary radiation.
Synthesis of a molecule found in guava plants offers hope in fighting liver-related cancers
You may not be aware that most of the medicines that have been approved for treatment are rooted in nature. For example, the bark of willow trees has been called nature’s aspirin because it contains a chemical called salicin. The human body converts salicin into salicylic acid, which relieves pain and fights fevers.
New research by William Chain, associate professor in the University of Delaware’s Department of Chemistry and Biochemistry, and his lab, uses a molecule found in a tropical fruit to offer hope in the fight against liver-related cancers, one of the world’s top causes of cancer deaths.
Using a process called natural product total synthesis, Chain and his lab group have invented a pathway that uses widely available chemicals to create molecules found in a guava plant that are known to fight these deadly cancers. The work is published in Angewandte Chemie.
