Chinese researchers make a major breakthrough in 6G communication

Use terahertz frequency communication and achieve ultra-fast communication.

Researchers at the China Aerospace Science and Industry Corporation Second Institute have achieved a breakthrough in next-generation 6G communication by conducting the first real-time wireless transmission, the South China Morning Post.

6G, short for the sixth generation cellular network, is the next frontier of telecommunications which promises more reliable and faster communication than any of the existing technologies.

Fluorescent blue coumarins in a folk-medicine plant could help us see inside cells

Plants that glow under ultraviolet (UV) light aren’t just inventions of science fiction TV and movies. Roots of a traditional medicine plant called the orange climber, or Toddalia asiatica, can fluoresce an ethereal blue hue. And now, researchers have identified two coumarin molecules that could be responsible. These natural coumarins have unique fluorescent properties, and one of the compounds could someday be used for medical imaging. Their study is published in ACS Central Science.

Fluorescent substances take in UV light that is directed on them and release vibrantly colored visible light. And some glow even more brightly when they are close together, a phenomenon seen in compounds called aggregation-induced emission luminogens (AIEgens). They are key components in some optical devices, cellular imaging techniques and environmental sensors. However, these molecules are usually made in a lab, and many are toxic. Some plants already have this ability, so, Ben Zhong Tang, Zheng Zhao, Xiao-Dong Luo and colleagues turned to nature to find naturally occurring and safer AIEgens.

The researchers dried orange climber roots, crushed them into a powder, and then isolated and identified coumarin compounds with aggregation-induced emission properties: 5-methoxyseselin (5-MOS) and 6-methoxyseselin (6-MOS). When dissolved in an , 5-MOS exhibited a blue-green glow and 6-MOS had a slightly dimmer blue glow. In addition, both AIEgens had low cytotoxicity and good biocompatibility.

AI breakthrough lets humans ‘talk’ with bats and bees ‘changing what we know’

Scientists have begun using artificial intelligence to help them communicate with animals — and they’re starting small with bats and bees.

AI allows humans to use breakthrough techniques to decode and observe how animals communicate so we can try to speak back to them.

Scientific American spoke with Professor Karen Bakker who is the author of the new book The Sounds of Life: How Digital Technology Is Bringing Us Closer to the Worlds of Animals and Plant.

Startup raises $28.5 million to construct gas stations in space that can refuel satellites

One of the most difficult issues in space exploration is extending the lifespan of satellites. Even if the satellite’s system is operational, it can run out of fuel and become defunct.

Enter Orbit Fab. This startup is working on an innovative solution to make satellites reusable by developing gas stations in space to refuel them. We had written about them in 2021.

Google CEO Sundar Pichai Says A.I.’s Potential Downsides Keep Him Up At Night

Google CEO Sundar Pichai believes artificial intelligence is the most profound technology in the history of human civilization—potentially more important than the discovery of fire and electricity—and yet even he doesn’t fully understand how it works, Pichai said in an interview with CBS’s 60 Minutes that aired yesterday (April 16).

“We need to adapt as a society for it…This is going to impact every product across every company,” Pichai said of recent breakthroughs in A.I. in a conversation with CBS journalist Scott Pelley. It’s the Google CEO’s second long-form interview in a two weeks as he apparently embarks on a charm offensive with the press to establish himself and Google as a thought leader in A.I. after the company’s latest A.I. product received mixed reviews.

Google in February introduced Bard, an A.I. chatbot to compete with OpenAI’s ChatGPT and Microsoft’s new Bing, and recently made it available to the public. In an internal letter to Google employees in March, Pichai said the success of Bard will depend on public testing and cautioned things could go wrong as the chatbot improves itself through interacting with users. He told Pelley Google intends to deploy A.I. in a beneficial way, but suggested how A.I. develops might be beyond its creator’s control.

James Webb telescope keeps finding galaxies that shouldn’t exist, scientist warns

The James Webb Space Telescope keeps finding galaxies that shouldn’t exist, a scientist has warned.

Six of the earliest and most massive galaxies that NASA’s breakthrough telescope has seen so far appear to be bigger and more mature than they should be given where they are in the universe, researchers have warned.

The new findings build on previous research where scientists reported that despite coming from the very beginnings of the universe, the galaxies were as mature as our own Milky Way.

Visual GPT 4: Unveiling 3 Next Gen AI Abilities + NEW OpenAI Model

OpenAI’s breakthrough consistency model will lead into image understanding to make GPT4 multimodal, providing next generation improvements with human-computer interaction, human-robot interaction, and even helping the disabled.

The Meminductor: A New Circuit Element

Researchers at Texas A&M University have discovered a novel circuit element referred to as a meminductor that led to a significant breakthrough in circuit elements.

In an electrical circuit, circuit elements play a crucial role in managing the flow of electricity. The resistor, capacitor, and inductor are the traditional circuit elements, while the memristor and memcapacitor are the more recent additions discovered in the past 15 years. These newer components, known as “mem-” versions of the classical elements, have different voltage and current characteristics that are influenced by previous voltage or current values over time, giving them memory-like properties.

Dr. H. Rusty Harris, an Associate Professor at the Department of Electrical and Computer Engineering at Texas A&M University, has made a significant breakthrough in circuit elements with the discovery of a new component called the meminductor.

New Method To Measure Brain Fluid Pressure Developed

West Australian researchers have developed a breakthrough method to measure the brain fluid pressure in humans, which may reduce vision damage experienced by astronauts on long-haul space flights.

A cross-disciplinary team from the Lions Eye Institute and the International Space Centre at The University of Western Australia has developed a clever technique to measure the pressure in the brain fluid, the study was published in Nature in npj Microgravity.
