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.

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.

Summary: A pioneering new prototype allows those with hearing loss to “listen” to music through the sense of touch.

People with hearing loss will be able to listen to music through the sense of touch thanks to a pioneering prototype that has been devised by researchers of the Department of Electronics of the University of Malaga, members of the R&D group “Electronics for instrumentation and systems”.

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.

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.

The ultimate goal of neuroscience is to learn how the human brain gives rise to human intelligence and what it means to be intelligent. Understanding how the brain works is considered one of humanity’s greatest challenges.

Jeff Hawkins thinks that the reality we perceive is a kind of simulation, a hallucination, a confabulation. He thinks that our brains are a model reality based on thousands of information streams originating from the sensors in our body. Critically — Hawkins doesn’t think there is just one model but rather; thousands.

Jeff has just released his new book, A thousand brains: a new theory of intelligence. It’s an inspiring and well-written book and I hope after watching this show; you will be inspired to read it too.

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).
