Scientists successfully connect âartificial neuronâ to biological cells in major step
đš A major breakthrough.
Scientists have successfully implanted an artificial neuron into a Venus Flytrap, in what could be a major breakthrough in the merging of living things and computers.
The neuron was able to control the plant, making its lobes close, the scientists report.
That in turn could be a major step towards the development of brain-machine interfaces as well as intelligent robots, they suggest. Such technology will require computers and living things to combine â but that has so far proven difficult.
A step closer to biodegradable household batteries
Fully organic rechargeable household batteries are an ideal alternative to traditional metal-based batteries, in particular for reducing pollution to landfill and the environment.
Now researchers at Flinders University, with Australian and Chinese collaborators, are developing an all-organic polymer battery that can deliver a cell voltage of 2.8Vâa big leap in improving the energy storage capability of organic batteries.
âWhile starting with small household batteries, we already know organic redox-active materials are typical electroactive alternatives due to their inherently safe, lightweight and structure-tunable features and, most importantly, their sustainable and environmentally friendly,â says senior lecturer in chemistry Dr. Zhongfan Jia, a research leader at Flinders Universityâs Institute for Nanoscale Science and Technology.

Strikes on Ukrainian positions have been reported following Russian President Vladimir Putinâs order of a military operation.
After sighting of âcube,â lunar rover discovers mysterious glass spheres on Moon
Chinese rover Yutu-2 has discovered mysterious glass spheres on the far side of the moon. The paper detailing the discovery has been published in Science Bulletin.
âCollectively, the peculiar morphology, geometry, and local context of the glass globules are consistent with being anorthositic impact glasses,â the researchers write in their paper.

Elon Muskâs Lawyer Accuses Government of âLeakingâ Information About Him
Elon Muskâs back at it again, folks â and this time, his attorney is accusing the federal government of leaking.
Following up on his claim that the Securities and Exchange Commission was trying to harass him into silence, Muskâs attorney accused the commission of âleaking certain informationâ in an ongoing retaliation campaign against the Tesla and SpaceX CEO.
This alleged campaign supposedly began back in 2018, when the SEC investigated Musk for tweeting about selling Tesla stock at $420 a share and taking the company private, eventually charging him with misleading investors. Though that case was settled in 2018 after Musk and Tesla paid $20 million each in fines, new reporting about the commission subpoenaing the CEO in recent months has reignited the debacle.
Tiny Space Probes Using âLaser Sailsâ Could Speed to Outer Planets and Beyond
Imagine a field of wheat that extends to the horizon, being grown for flour that will be made into bread to feed citiesâ worth of people. Imagine that all authority for tilling, planting, fertilizing, monitoring and harvesting this field has been delegated to artificial intelligence: algorithms that control drip-irrigation systems, self-driving tractors and combine harvesters, clever enough to respond to the weather and the exact needs of the crop. Then imagine a hacker messes things up.
Risks of using AI to grow our food are substantial and must not be ignored, warn researchers

A new risk analysis, published today in the journal Nature Machine Intelligence, warns that the future use of artificial intelligence in agriculture comes with substantial potential risks for farms, farmers and food security that are poorly understood and under-appreciated.
âThe idea of intelligent machines running farms is not science fiction. Large companies are already pioneering the next generation of autonomous ag-bots and decision support systems that will replace humans in the field,â said Dr. Asaf Tzachor in the University of Cambridgeâs Center for the Study of Existential Risk (CSER), first author of the paper.
Mind-bending new quantum experiments are blurring past, present and future
A professor of physics explains how mind-bending quantum experiments are blurring the line between past, present and future. Further, he argues, these experiments, which factor in âthe relevance of the future to the presentâ, may demand a radical rethinking of quantum experimentation itself.
