Alien life: Leaking radio waves and hidden megastructures could hint at extraterrestrials

Posted by in categories: alien life, electronics

Could we describe and search for proof of technology originating from outside of Earth?

If an alien were to look at Earth, many human technologies — from cell towers to fluorescent light bulbs — could be a beacon signifying the presence of life.

We are two astronomers who work on the search for extraterrestrial intelligence — or SETI. In our research, we try to characterize and detect signs of technology originating from beyond Earth. These are called technosignatures. While scanning the sky for a TV broadcast of some extraterrestrial Olympics may sound straightforward, searching for signs of distant, advanced civilizations is a much more nuanced and difficult task than it might seem. iStock.

New corrosion-detecting tech detects leaks in pipes before they occur

Posted by in category: electronics

Pipeline corrosion resulting in leaks is very common. There are only a few current methods to detect defects before they cause leaks. Often, the pipe is repaired and re-inspected after a leak occurs.

Now, Southwest Research Institute (SwRI) has created the next generation of transducers that use ultrasonic-guided wave technology to detect anomalies in pipes, enabling users to prevent leaks before they start.

Originally developed by SwRI in 2002, the technology is known as a Magnetostrictive Transducer (MsT) Collar. The updated version has a flat, thin design, which allows it to be used on pipes in tight spaces. The new MsT design also features eight sensors that give the transducer the ability to consistently monitor the pipe’s condition and accurately identify where the pipe corrosion is occurring, hopefully preventing leaks from happening in the first place.

2022 Will See 5.3 Billion Phones Discarded, Experts Warn

Posted by in categories: electronics, mobile phones

We have a serious e-waste problem, according to the international waste electrical and electronic equipment (WEEE) forum. This year alone, 5.3 billion mobile phones will go to landfills, the organization told the BBC on Friday.

Precious minerals left to waste

This means that a lot of the precious minerals that cannot be extracted from waste electronics, such as the copper in wire or the cobalt in rechargeable batteries, will have to be mined, a notoriously polluting activity.

Caltech’s New Ultrafast Camera Captures Signals Traveling Through Nerve Cells

Posted by in categories: electronics, neuroscience

Reach out right now and touch anything around you. Whether it was the wood of your desk, a key on your keyboard, or the fur of your dog, you felt it the instant your finger contacted it.

Or did you?

In actuality, takes a bit of time for your brain to register the sensation from your fingertip. However, it does still happen extremely fast, with the touch signal traveling through your nerves at over 100 miles per hour. In fact, some nerve signals are even faster, approaching speeds of 300 miles per hour.

A New, Disposable Paper Battery Has Been Developed

Posted by in categories: biotech/medical, electronics

A proof-of-concept study published in the journal Scientific Reports outlines a water-activated disposable paper battery. According to the scientists, it could be used to power a broad variety of low-power, single-use disposable electronics, such as smart labels for tracking items, environmental sensors, and medical diagnostic devices, thereby minimizing their environmental impact.

The battery was developed by Gustav Nyström and colleagues, and it consists of at least one cell that is one centimeter squared and is made up of three inks that have been printed on a rectangular piece of paper. The paper strip is covered with sodium chloride salt, and one of its shorter ends has been dipped in wax.

One of the flat sides of the paper is printed with ink containing graphite flakes, which serves as the positive end of the battery (cathode). The other side is printed with ink containing zinc powder, which serves as the negative end of the battery (anode).
