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.

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).

The device costs $60 to make and can be applied in the lab in minutes.

Atomically thin materials such as graphene have drawn attention for how electrons can race in them at exceptionally quick speeds, leading to visions of advanced new electronics. Now scientists find that similar behavior can exist within two-dimensional sheets, known as domain walls, that are embedded within unusual crystalline materials. Moreover, unlike other atomically thin sheets, domain walls can easily be created, moved, and destroyed, which may lead the way for novel circuits that can instantly transform or be repaired on command.

In the new study, researchers investigated crystalline lithium niobate ferroelectric film just 500 nanometers thick. Electric charges within materials separate into positive and negative poles, and ferroelectrics are materials in which these electric dipoles are generally oriented in the same direction. The electric dipoles in ferroelectrics are clustered in regions known as domains. These are separated by two-dimensional layers known as domain walls.

The amazing electronic properties of two-dimensional materials such as graphene and molybdenum disulfide have led researchers to hope they may allow Moore’s Law to continue once it becomes impossible to make further progress using silicon. Researchers have also investigated similarly attractive behavior in exceptionally thin electrically conducting heterointerfaces between two different insulating materials, such as lanthanum aluminate and strontium titanate.

Singer is the founder and director of Outreach Judaism, a Jewish counter-missionary organization. It describes itself as “an international organization that responds directly to the issues raised by missionaries and cults, by exploring Judaism in contradistinction to fundamentalist Christianity.” Singer cautions regarding congregations that “are designed to appear Jewish, but are actually fundamentalist Christian churches, which use traditional Jewish symbols to lure the most vulnerable of our Jewish people into their ranks.” Outreach Judaism was described by J. Gordon Melton in 2002 as an example of “the current state of Jewish counter-cult activity.”

Rabbi Tovia Singer wanted to understand why Jews have been persecuted throughout history so he read the New Testament and found out why they have been targeted. It appears Rabbi Tovia Singer has devoted his life to showing how the authors of the New Testament corrupted the Hebrew scriptures in the Septuagint. He shows how Paul manipulated the text just as bad as modern tv preachers to suite his gentile audience.
