There’s No Such Thing As Too Many Hobbies—A Psychologist Explains

Posted by in category: futurism

Some people come to therapy feeling overwhelmed and uncertain about their tendency to pick up and put down hobbies on a whim. They ask questions like:“Why do I feel so scattered, hopping from one interest to another?”

“Is it normal to want to learn so many things, or am I just avoiding commitment?”“Why do I feel like I’m not truly excelling in any one area despite my many pursuits?”

The pervasive cultural narrative has often celebrated specialization, making those with multifaceted interests feel out of place. Society has long valued depth over breadth, equating mastery in a single field with success and purpose. This has led to a collective anxiety: the fear of missing out on becoming an… More.

Bigger Isn’t Always Better When It Comes To Generative AI

Posted by in category: robotics/AI

The explosive recent growth of AI tools to generate text, images, or audio relies on gargantuan amounts of information.

That information doesn’t come for free. It can exact high – and unequal – costs in terms of energy, water, and labor, though these costs are largely invisible to users.

In terms of energy, generative AI models typically depend on extremely large-scale cloud providers, which use chips with more transistors that require at least 10 times as much energy as traditional versions. Unsurprisingly, models that use more training data and contain more parameters tend to guzzle more energy.

A Day Without Space: GPS Is Ground Zero For The New Space Race

Posted by in categories: economics, education, government, robotics/AI, satellites, security

The 2 SOPS or 2nd Space Operations Squadron commander, Lt Col Robert Wray… More.

Of all the missions the Space Force performs daily for a grateful nation, there is none more ubiquitous and essential than GPS. Today’s soldiers and sailors depend on reliable, accurate, and secure GPS as much as they do any weapon they employ. Meanwhile, the rest of the world is just as dependent on GPS to enable basic mobility and underpins every other sector of the modern global economy. The criticality of secure global navigation and timing to both warfighting and the national economy makes it unique – we simply could not go a day without space. In so few words, GPS’ future is ground zero for the new space race.

The 2 SOPS or 2nd Space Operations Squadron commander, Lt Col Robert Wray reminds me that “14 of the 16 critical infrastructures designated by the Department of Homeland Security rely on 24/7 GPS to operate for the country.” But the newest GPS satellites in use today are the same school bus sized ones Gen. Hyten has lamented are, “juicy targets” for our adversaries – marvels of modern engineering, yes, but no longer sufficient to meet modern needs.

New nitrogen isotope stretches our understanding of nuclear physics

Posted by in category: physics

Indirect observations of a strange isotope of nitrogen, nitrogen-9, could open new avenues of understanding of nuclear theory.

A group of researchers has discovered direct evidence of a new atomic nucleus that stretches what we understand of nuclear physics. Called nitrogen-9, this isotope contains seven protons and two neutrons and only exists for one billionth of a nanosecond. That is such a minute amount of time that it is difficult for scientists to agree if this really is an atomic isotope or not.

A new wearable sensor can monitor sweat in real time

Posted by in categories: biotech/medical, food, health, wearables

The patch can calibrate the glucose measurements based on the pH and temperature changes in sweat due to factors such as exercise and eating.

A team of researchers at Penn State has developed a new wearable patch that can monitor your health by analyzing your sweat. The patch, which is made of a special material that can detect glucose, pH, and temperature in sweat, can provide valuable information about your body’s condition and help diagnose and manage diseases such as diabetes.

Llama 2 Long outperforms other AI models in long queries

Posted by in categories: innovation, robotics/AI

Llama 2 Long is an extension of Llama 2, an open-source AI model that Meta released in the summer.

While Meta Platforms unveiled several new AI-powered features for its popular apps like Facebook, Instagram, and WhatsApp at its annual Meta Connect event in California this week, the most impressive innovation from the social media giant may have gone unnoticed by many.

A team of Meta researchers quietly published a paper introducing Llama 2 Long, a new AI model that can generate coherent and relevant responses to long user queries, surpassing some of the best competitors in the field.

Codec avatars: The next frontier of Meta’s VR technology

Posted by in categories: finance, virtual reality

Meta CEO Mark Zuckerberg reveals the technology behind codec avatars, which create ultra-realistic VR faces.

Meta, formerly known as Facebook, has been struggling to convince the world that its vision of the metaverse is worth pursuing. The social media giant rebranded itself in October 2022, hoping to create a more immersive and interactive online experience for its users. However, the initial response was far from positive. Many people mocked the cartoonish and unrealistic avatars that Meta showcased in its demonstration video, which lasted for over an hour. Others questioned the need and feasibility of creating a virtual world that mimics real life.

Meta’s ambitious project also faced… More.

Migraine headaches: What are they and how do you treat them?

Posted by in categories: education, food

The first time it happened, I was in a high school physics class. Suddenly, I couldn’t read half of the board. A crack zig-zagged through my vision, obscuring my teacher’s notes. “Huh,” I thought. “This can’t be good.”

My classmate walked me to the school nurse, who called my mom. Pain rippled from the back of my neck to my forehead. I’d had headaches before, but not like this. “Ah, your first migraine,” Mom said. “Welcome to the club.”

For nearly a billion people worldwide, migraine attacks disrupt work, vacation and school. They can be triggered by stress, weather changes, hormone shifts, missed meals or sleep changes — in other words, just about anything. These reoccurring headaches often spur pain on one side of the head. They can last a few hours or a few days, and they can cause nausea along with sensitivity to noises and light.
