As everyday technologies get more and more advanced, cyber security must be at the forefront of every customer. Cyber security services have become common and are often used by private companies and the public sector in order to protect themselves from potential cyber attacks.

One of these services goes under the name Darktrace and has recently been acquired by Cybersprint, a Dutch provider of advanced cyber security services and a manufacturer of special tools that use machine learning algorithms to detect cyber vulnerabilities. Based on attack path modeling and graph theory, Darktrace’s platform represents organizational networks as directional, weighted graphs with nodes where multi-line segments meet and edges where they join. In order to estimate the probability that an attacker will be able to successfully move from node A to node B, a weighted graph can be used. Understanding the insights gained will make it easier for Darktrace to simulate future attacks.

PITTSBURGH (KDKA) — Move over, BA-4 and BA-5, there’s a new COVID-19 variant that’s spreading even as the push is on for the current round of boosters.

The word from the experts is to get the booster and don’t let your guard down. KDKA’s John Shumway spoke with CBS News medical expert Dr. David Agus — and some of what he had to say is a bit disconcerting.

Alpha, Beta, Gamma, Delta, Omicron, BA-4, BA-5, and now comes BF-7.

There needs to be a radical change to biological wetware in order to handle viruses. What is needed is either nanoparticles or an immunity to all diseases. Crispr is the main path for the biological singularity but it needs to be perfected first as the human body is still a black box due to restrictions. I do believe that mass spectrometry will essentially be key to see the inner world of human biology. Then crispr can make new parts essentially to evolve past our current limits. But either way the biological singularity is needed for survival of human beings for better health.

The coronavirus revealed flaws in the nation’s pandemic plans. The spread of monkeypox shows that the problems remain deeply entrenched.

New Curtin University-led research has found that the world’s next supercontinent, Amasia, will most likely form when the Pacific Ocean closes in 200 to 300 million years.

Published in National Science Review, the research team used a supercomputer to simulate how a forms and found that because the Earth has been cooling for billions of years, the thickness and strength of the plates under the oceans reduce with time, making it difficult for the next supercontinent to assemble by closing the “young” oceans, such as the Atlantic or Indian oceans.

Lead author Dr. Chuan Huang, from Curtin’s Earth Dynamics Research Group and the School of Earth and Planetary Sciences, said the new findings were significant and provided insights into what would happen to Earth in the next 200 million years.

Jennifer Garrison, Buck Institute.
Reframing Health and Aging through the Lens of Reproduct.

Jennifer Garrison is an assistant professor at the Buck Institute for Research on Aging and also holds appointments in the Department of Cellular and Molecular Pharmacology at University of California, San Francisco (UCSF) and the Davis School of Gerontology at the University of Southern California. During her doctoral studies at UCSF with Jack Taunton, she discovered the molecular target of a natural product and elucidated a novel mechanism by which small molecules can regulate protein biogenesis.

Brain-age (BA) estimates based on deep learning are increasingly used as neuroimaging biomarker for brain health; however, the underlying neural features have remained unclear. We combined ensembles of convolutional neural networks with Layer-wise Relevance Propagation (LRP) to detect which brain features contribute to BA. Trained on magnetic resonance imaging (MRI) data of a population-based study (n = 2,637, 18–82 years), our models estimated age accurately based on single and multiple modalities, regionally restricted and whole-brain images (mean absolute errors 3.37–3.86 years). We find that BA estimates capture ageing at both small and large-scale changes, revealing gross enlargements of ventricles and subarachnoid spaces, as well as white matter lesions, and atrophies that appear throughout the brain. Divergence from expected ageing reflected cardiovascular risk factors and accelerated ageing was more pronounced in the frontal lobe. Applying LRP, our study demonstrates how superior deep learning models detect brain-ageing in healthy and at-risk individuals throughout adulthood.
