New AI-based tool shows promise in accurately identifying lung cancer

The AI model employs radiomics, a technique for extracting critical information from medical images that are not always visible to the naked eye.

An artificial intelligence (AI) model that accurately identifies cancer has been developed by a team of scientists, doctors, and researchers from Imperial College London, the Institute of Cancer Research in London, and the Royal Marsden NHS Foundation Trust.

Reportedly, this new AI model uses radiomics, a technique that extracts critical information from medical images that may not be visible to the naked eye. This, in turn, aids in determining whether the abnormal growths detected on CT scans are cancerous.

A new COVID variant called Arcturus is linked to pink eye. Here’s what you need to know

About 1 in 10 cases of COVID-19 nationwide is caused by an emerging coronavirus strain, XBB.1.16.

The World Health Organization has elevated this strain of omicron to one of two “circulating variants of interest.” The variant, which has been called Arcturus, is responsible for a growing share of coronavirus cases in the United States.

As of April 22, it caused 9.6% of COVID-19 infections nationwide, according to the Centers for Disease Control and Prevention.

The Passwordless Revolution Has Arrived

At last, we’re on the cusp of a passwordless era. Replacing passwords with passkeys promises to reduce frustration while making us safer.

However, through my experience working with businesses and end users, I’ve found widespread misunderstandings around passwordless technologies. Many don’t understand what passwordless technology is or how it works, and some mistakenly think that more onerous login processes mean it’s more secure. Here’s an update on where we stand and what we need to take passwordless technology mainstream.

Passwords may be the default, but they’re not our best option.

Wearable devices may be able to capture well-being through effortless data collection using AI

Applying machine learning models, a type of artificial intelligence (AI), to data collected passively from wearable devices can identify a patient’s degree of resilience and well-being, according to investigators at the Icahn School of Medicine at Mount Sinai in New York.

The findings, reported in the May 2 issue of JAMIA Open, support , such as the Apple Watch, as a way to monitor and assess psychological states remotely without requiring the completion of mental health questionnaires.

The paper, titled “A machine learning approach to determine utilizing wearable device data: analysis of an observational cohort,” points out that resilience, or an individual’s ability to overcome difficulty, is an important stress mitigator, reduces morbidity, and improves chronic disease management.

A Clean Energy Future Starts With An Efficient Grid

That’s when major clean energy projects are also due to come online, including the country’s largest offshore wind farm, which comes at a price of $9.8 billion. Once built off the Virginia coast, this project could save the state’s customers as much as $6 billion during its first 10 years in operation.

Focusing on efficiency now will help avoid overbuilding renewable generation and allow such large-scale projects to make great strides toward a greener grid when they finally are welcomed online.

While making energy efficiency improvements isn’t a new idea, AI is enabling real-time data analysis and energy intelligence that can maximize efforts in a variety of ways that are chipping away at carbon emissions now.

The Israelis bringing us big science in little soundbites

Forget about evolution, climate change or vaccines – what makes people really lose their mind, apparently, is cats.

“We’ve had posts that have affected people’s lives in a very substantial way, including posts that went beyond the virtual world. People really got threats or disrespectful comments,” says Yomiran Nissan.

“For example, when we wrote about the very, very viral topic of street cats and the ecological problems that they pose. It led to a lot of anger, both virtual and in the real world.”

Bio-nano approach flips artificial photosynthesis for hydrogen on its head

An artificial photosynthesis system that combines semiconducting nanoparticles with a non-photosynthetic bacterium could offer a promising new route for producing sustainable solar-driven hydrogen fuel.

Other artificial photosynthesis systems that integrate nanomaterials into living microbes have been developed before, which reduce carbon dioxide or produce hydrogen, for example. However, usually it is the microorganism itself that makes the product via a metabolic pathway, which is aided by a light-activated nanomaterial that supplies necessary electrons.

Now, the labs of Kara Bren and Todd Krauss at the University of Rochester, US, have turned this concept on its head. They have designed a new hybrid bio-nano system that combines a finely-tuned photocatalytic semiconducting nanoparticles to make hydrogen with a bacterium which, while it does not photosynthesise or make hydrogen itself, it provides the necessary electrons to the nanomaterial to synthesise hydrogen.
