A First-of-Its-Kind Signal Was Detected in The Human Brain : ScienceAlert

Scientists have identified a unique form of cell messaging occurring in the human brain, revealing just how much we still have to learn about its mysterious inner workings.Excitingly, the discovery hints that our brains might be even more powerful units of computation than we realized.Back in 2020, researchers from institutes in Germany and Greece reported a mechanism in the brain's outer cortical cells that produces a novel 'graded' signal all on its own, one that could provide individual neurons with another way to…

Shocking Study Finds Microplastics in Every Human Placenta

By Michael Haederle, University of New Mexico Health Sciences Center February 27, 2024Researchers at the University of New Mexico have discovered microplastics in all tested human placenta samples, revealing a concerning presence of these particles in the human body.Microplastics detected in all examined human placentas point to significant environmental contamination and health risks, with future research needed to understand the full implications.A flurry of recent studies has found that microplastics are present in…

The Odysseus lunar mission ends following human error on Earth

The IM-1 Moon landing mission will come to a premature end on Tuesday morning. Intuitive Machines has announced that the Odysseus lander will no longer be able to charge its batteries by February 27 as sunlight stops falling on its solar panels.Today's announcement is a bittersweet end for a mission that survived tipping over on landing and the failure of a vital navigation system due to human error. When 'Odie' touched down on the Moon on February 22, it did so with the aid of a NASA experimental navigation system that…

How to make your AI-generated content sound more human

Generative AI tools like ChatGPT can create content, but it doesn’t always sound natural. The content can come across as dull or robotic without the right guidance. Fortunately, there are techniques you can use to make AI-written text more human-like, engaging and fun to read. This article will explore ways to get more life-like, conversational content from AI. Specifically, we’ll look at how to customize the prompts you give ChatGPT so it better understands the tone, emotion and audience you want to target.

Wikimedia’s CTO: In the age of AI, human contributors still matter

What Deckelmann means by “sustainability” is a pressing concern in the open-source space more broadly. When complex services or entire platforms like Wikipedia depend on the time and labor of volunteers, contributors may not get the support they need to keep going—and keep those projects afloat. Building sustainable pathways for the people who make the internet has been Deckelmann’s personal passion for years. In addition to working as an engineering and product leader at places like Intel and Mozilla and contributing to…

Tiny Doses of LSD Boost Unique Signals in The Human Brain : ScienceAlert

Even small doses of LSD could have therapeutic benefits for mental health and task performance, a new study shows.Researchers from the US and Germany gave 21 adults either a placebo or 13 or 26 micrograms of LSD – small doses that rarely lead to hallucinatory effects.It was found that 26 micrograms of the psychoactive compound increased brain complexity by about 12 percent compared to a placebo, without altering consciousness. Neural complexity is a measure of unique brain signals, usually correlating with consciousness…

Microplastics Found in Every Human Placenta Tested, Study Finds : ScienceAlert

It's been over three years since scientists first found microplastics swimming in four different human placentas, and as it turns out, that was just the tip of the iceberg.A few years later, at the start of 2023, researchers announced they had found microscopic particles of plastic waste in no fewer than 17 different placentas. By the end of 2023, a local study in Hawai'i analyzed 30 placentas that were donated between 2006 and 2021 only to find plastic contamination had increased significantly over time.Using a new…

Google strikes $60 million deal with Reddit, allowing search giant to train AI models on human posts

Google has struck a deal with Reddit that allows the search giant to use posts from the online discussion site for training its artificial intelligence models and to improve services such as Google Search. The arrangement, announced Thursday and valued at roughly $60 million, will also give Reddit access to Google AI models for improving its internal site search and other features. Reddit declined to comment or answer questions beyond its written statement about the deal.Separately, the San Francisco-based company…

The Human Toll of Greg Abbott’s War at the Border

EAGLE PASS, Texas — The video is 13 seconds long. In the foreground is an orderly green lawn, lit and safe. In the background, there are the lights of Mexico, Coahuila state. In the middle is the river. It’s a void, darker than the night sky.  Amid crickets, a woman’s voice echoes from the void, or maybe a child’s. Then a man’s. They’re crying out for help. The lawn belongs to former state Rep. Poncho Nevárez (D), who represented Eagle Pass in the Texas Legislature for eight years. Some time back, the state…
