Progress is speeding up even as the world barrels toward one of innumerable disasters. What lies ahead, and what should we do when we get there? In the best-case scenario, we may still have control over our direction.

Summary: A newly designed dry sensor that can measure brain activity may someday enable mind control of robotic systems.

It sounds like something from science fiction: Don a specialized, electronic headband and control a robot using your mind. But now, recent research published in ACS Applied Nano Materials has taken a step toward making this a reality.
Ectogenesis—gestation using an artificial womb—is fast approaching reality. Yet without legislation, this innovation also has the potential to cause harm.
One day in the future, we may interact with our electronic devices not with physical input or even voice commands, but simply by thinking about what we want to do. Such brain–computer interfaces (BCIs), combined with machine learning, could allow us to turn our ideas into reality faster and with less effort than ever before — imagine being able to produce a PCB design simply by thinking about how the completed circuit would work. Of course as an assistive technology, BCIs would be nothing less than life-changing for many.
Today BCIs are in their infancy, but that doesn’t mean there isn’t room for hackers and makers to experiment with the concept. [Ildar Rakhmatulin] has been working on low-cost open source BCIs for years, and with the recent release of his PiEEG on Crowd Supply, thinks he’s finally found an affordable solution that will let individuals experiment with this cutting edge technology.
Implemented as a shield that can be connected to a Raspberry Pi 3 or 4, the PiEEG features 8 channels for connecting wet or dry electrodes that can measure biosignals such as those used in electroencephalography (EEG), electromyography (EMG), and electrocardiography (ECG). With the electrodes connected, reading these biosignals is as easy as running a Python script. While primarily designed for neuroscience experimentation, [Ildar] says the device is also useful for learning more about signal processing, filters, and machine learning.
Scientists have achieved a “temporal analogue” to the famous double-slit experiment that could lead to new optical technologies. ABSTRACT breaks down mind-bending scientific research, future tech, new discoveries, and major breakthroughs. Scientists have discovered “unexpected physics” by opening up “slits” in time, a new study reports, achieving a longstanding dream that can help to probe the behavior of light and pioneer advanced optical technologies.
The first SPAD camera.
TOKYO, April 3, 2023—Canon Inc. announced today that the company is developing the MS-500, the world’s first1 ultra-high-sensitivity interchangeable-lens camera (ILC) equipped with a 1.0 inch Single Photon Avalanche Diode (SPAD) sensor2 featuring the world’s highest pixel count of 3.2 megapixels3. The camera leverages the special characteristics of SPAD sensors to achieve superb low-light performance while also utilizing broadcast lenses that feature high performance at telephoto-range focal lengths. Thanks to such advantages, the MS-500 is expected to be ideal for such applications as high-precision monitoring.
Fat molecules serve as energy storage for fat cells. They consist of three fatty acids attached to a backbone of glycerol. They are therefore also called triglycerides. It has long been suspected that molecules do not remain unchanged during their storage period. Instead, they are regularly broken down and reassembled—a process called “triglyceride cycling.”
But is this assumption even true, and if so: What would that be good for? “Until now, there has been no real answer to these questions,” explains Prof. Dr. Christoph Thiele of the LIMES Institute at the University of Bonn. “It’s true that there has been indirect evidence of this permanent reconstruction for the past 50 years. However, direct evidence of this has so far been lacking.”
The problem: To prove that triglycerides are broken down, and fatty acids modified and reincorporated into new molecules, one would need to track their transformation as they travel through the body. Yet there are thousands of different forms of triglycerides in each cell. Keeping track of individual fatty acids is therefore extremely difficult.
