Pediatric cardiologist Mohammed Numan, MD, recently appeared on KHOU-11 to talk about sudden cardiac arrest in adolescents when playing sports. He shares signs that parents and teachers should be aware of and what tools and training they should have.

Although it’s rare, doctors at UT Physicians want parents and teachers to know when a student-athlete has a sudden cardiac arrest.
Knowing how to dispose of a printer could mean the difference between protecting personal data and letting it fall into the wrong hands.
A threat actor who claimed responsibility for the compromise of the 23AndMe site earlier this month has released a new dataset, including the records of more than 4 million people’s genetic ancestry.
The cybercriminal, known by the handle Golem, alleges in a cybercrime Dark Web forum the stolen data includes information on, “the wealthiest people living in the US and Western Europe,” according to reports.
23andMe spokesperson Andy Kill said in a statement the organization is still trying to confirm whether the most recently leaked data is genuine.
Little is as important for the future of the world, and our own lives, as how this history continues.
A 25-year-old wager is settled as a new generation of scientists takes on competing theories of consciousness.
If you wanted to, you could access an “evil” version of OpenAI’s ChatGPT today—though it’s going to cost you. It also might not necessarily be legal depending on where you live.
However, getting access is a bit tricky. You’ll have to find the right web forums with the right users. One of those users might have a post marketing a private and powerful large language model (LLM). You’ll connect with them on an encrypted messaging service like Telegram where they’ll ask you for a few hundred dollars in cryptocurrency in exchange for the LLM.
Once you have access to it, though, you’ll be able to use it for all the things that ChatGPT or Google’s Bard prohibits you from doing: have conversations about any illicit or ethically dubious topic under the sun, learn how to cook meth or create pipe bombs, or even use it to fuel a cybercriminal enterprise by way of phishing schemes.
Geoscientists discovered a continent that had been hiding in plain sight for almost 375 years.
Historically, there’s been speculation about whether a continent known as Zealandia or Te Riu-a-Māui in the Māori language exists.
According to TN News, Zealandiais 1.89 million square miles in size. It was part of a supercontinent called Gondwana, which included most of Western Antarctica and Eastern Australia, over 500 million years ago.
When humans make decisions, such as picking what to eat from a menu, what jumper to buy at a store, what political candidate to vote for, and so on, they might be more or less confident with their choice. If we are less confident and thus experience greater uncertainty in relation to their choice, our choices also tend to be less consistent, meaning that we will be more likely to change our mind before reaching a final decision.
While neuroscientists have been exploring the neural underpinnings decision-making for decades, many questions are still unanswered. For instance, how neural network computations support decision-making under varying levels of certainty remain poorly understood.
Researchers at the National Institute of Mental Health in Bethesda, Maryland recently carried out a study on rhesus monkeys aimed at better understanding the neural network dynamics associated with decision confidence. Their paper, published in Nature Neuroscience, offers evidence that energy landscapes in the prefrontal cortex can predict the consistency of choices made by monkeys, which is in turn a sign of the animals’ confidence in their decisions.
An international team of interdisciplinary researchers has successfully created a method for better 3D modeling of complex cancers. The University of Waterloo-based team combined cutting-edge bioprinting techniques with synthetic structures or microfluidic chips. The method will help lab researchers more accurately understand heterogeneous tumors: tumors with more than one kind of cancer cell, often dispersed in unpredictable patterns.
The research, “Controlled tumor heterogeneity in a co-culture system by 3D bio-printed tumor-on-chip model,” appears in Scientific Reports.
Traditionally, medical practitioners would biopsy a patient’s tumor, extract cells, and then grow them in flat petri dishes in a lab. “For 50 years, this was how biologists understood tumors,” said Nafiseh Moghimi, an applied mathematics post-doctoral researcher and the lead author of the study. “But a decade ago, repeated treatment failures in human trials made scientists realize that a 2D model does not capture the real tumor structure inside the body.”
The simulated universe theory implies that our universe, with all its galaxies, planets and life forms, is a meticulously programmed computer simulation. In this scenario, the physical laws governing our reality are simply algorithms. The experiences we have are generated by the computational processes of an immensely advanced system.
While inherently speculative, the simulated universe theory has gained attention from scientists and philosophers due to its intriguing implications. The idea has made its mark in popular culture, across movies, TV shows and books—including the 1999 film “The Matrix.”
The earliest records of the concept that reality is an illusion are from ancient Greece. There, the question “What is the nature of our reality?” posed by Plato (427 BC) and others, gave birth to idealism. Idealist ancient thinkers such as Plato considered mind and spirit as the abiding reality. Matter, they argued, was just a manifestation or illusion.
