AI humanoid robot Sophia delivers a historic commencement speech at D’Youville University, marking a new era in education and technology.
In good news for future animation figureheads, there might be a new way to revive frozen brains without damaging them. Scientists in China have developed a new chemical concoction that lets brain tissue function again after being frozen.
Freezing is effective at keeping organic material from decomposing, but it still causes damage. As the water inside turns to ice, the crystals tear apart the cells. That’s why frozen meat or fruit goes a bit mushy after it’s defrosted – but a bigger problem is that it also happens with organs or tissues chilled for transplant or research.
For the new study, scientists at Fudan University in China experimented with various chemical compounds to see which ones might work to preserve living brain tissue during freezing. They started by testing out promising chemicals on brain organoids – small, lab-grown lumps of brain tissue that develop into different types of related cells.
A battery made from zinc and lignin that can be used over 8,000 times has been developed by researchers at Linköping University, Sweden, with a vision to provide a cheap and sustainable battery solution for countries where access to electricity is limited. The study has been published in the journal Energy & Environmental Materials.
Two-terminal devices are electronic components connected to electrical circuits via two electrical terminals. Although these components are the key building blocks of most existing devices, they can limit a system’s performance and functions.
A team of AI researchers at AWS AI Labs, Amazon, has found that most, if not all, publicly available Large Language Models (LLMs) can be easily tricked into revealing dangerous or unethical information.
In 1998, a paper linking childhood vaccines with autism was published in the journal, The Lancet, only to be retracted in 2010 when the science was debunked.
Most people agree that the spread of online misinformation is a serious problem. But there is much less consensus on what to do about it.
Strong field quantum optics is a rapidly emerging research topic, which merges elements of non-linear photoemission rooted in strong field physics with the well-established realm of quantum optics. While the distribution of light particles (i.e., photons) has been widely documented both in classical and non-classical light sources, the impact of such distributions on photoemission processes remains poorly understood.
We’re closer than ever to being able to upload our minds and become “digitally immortal.” But should we?
Experiments generate quantum entanglement over optical fibres across three real cities, marking progress towards networks that could have revolutionary applications.
