What do horses, armadillos, sloths, and tapirs all have in common? They’re all animals, sure. They’re all mammals, too. But there’s something more striking, more special, about them: Around 500,000 years ago, they all fell into the same sinkhole along Florida’s Steinhatchee River. Sediments filled their sinkhole thereafter, trapping them there until they were found, fossilized, in 2022. Today, these animals provide insights into Florida’s Middle Irvingtonian Period, a forgotten age fro ...read more

The Inner Ear Reveals Neanderthals May Have Went Through Great Genetic Loss

Posted on Categories Discover MagazineLeave a comment on The Inner Ear Reveals Neanderthals May Have Went Through Great Genetic Loss

Ears are incredible things. They help us process sound and play a significant role in our balance. They may have also just helped researchers gain a better understanding of Neanderthal evolution. Neanderthals emerged around 250,000 years ago from pre-Neanderthals populations (500,000 years to 250,000 years ago). These populations roamed Eurasia. For years, researchers believed that as pre-Neanderthals evolved into early Neanderthals and then into classic Neanderthals, there was little evolution ...read more

Lack of Sleep Weakens Our Memory Control, Allowing Intrusive Thoughts to Invade

Posted on Categories Discover MagazineLeave a comment on Lack of Sleep Weakens Our Memory Control, Allowing Intrusive Thoughts to Invade

From time to time, our conscious mind is invaded by unpleasant memories, often triggered by small occurrences in our surroundings. Typically, we can push these memories aside quickly, reducing the likelihood of future intrusions. However, individuals suffering from depression, anxiety, or post-traumatic stress disorder (PTSD) often spend more time trapped in cycles of intrusive thinking, reinforcing negative rumination. Given that people with mental health issues frequently experience sleep dist ...read more

Posted on Categories Discover MagazineLeave a comment on Can AI Coding Systems Earn $1 Million As Freelancers?

Freelance software engineering is a lucrative and dynamic field where skilled developers tackle diverse challenges, from bug fixes to full-stack feature development. In recent years, these workers have been among the first to incorporate AI systems into their workflow to help write code. That raises an interesting question: could an AI system do the same job by itself? In other words, have software engineers effectively developed themselves out of their own jobs?Now we get an answer of sorts tha ...read more

A Compass Works Differently in Space, Varying Widely From Planet to Planet

Posted on Categories Discover MagazineLeave a comment on A Compass Works Differently in Space, Varying Widely From Planet to Planet

Explorers have long trusted compasses to navigate Earth’s land and oceans, using our planet’s global magnetic field as their guide. But what happens when you take a compass beyond Earth — into orbit, to the Moon, to other planets, or even beyond our solar system? Would it still point north, or would it aimlessly spin in the absence of a dominant magnetic field? The answer depends on where you are in the cosmos and what other magnetic fields are at play.On Earth, a compass needle aligns wit ...read more

New Microsoft Quantum Computing Chip Could Revolutionize the Industry

An experimental Microsoft computer chip under development will deliver a one-two tech punch, according to the company.The first blow is a statement that Microsoft scientists have developed the first-ever quantum-computing chip in its class. This form of computing could theoretically make, ahem, quantum leaps in both speed and number of calculations a computer could perform simultaneously.The physics that theoretically would power such a chip is hard to understand — even for some physicists.“ ...read more

Feelings of exclusion aren’t all that fun. And they aren’t all that unusual, either, at least not for narcissists. According to a new study in the Journal of Personality and Social Psychology, narcissists are more likely to feel left out than non-narcissists, partially due to their actual exclusion and partially due to their perceived exclusion.“Feeling ostracized is a subjective experience based on the perception of social cues by the individual,” said Christiane Büttner, a study autho ...read more

In a hopeful step for medicine, a 2-and-a-half-year-old child born with spinal muscular atrophy (SMA) has shown no symptoms of the genetic condition, all thanks to a gene-targeting drug that the mother took during late pregnancy.A new study details this breakthrough case of prenatal therapy that holds promise for future treatment of the neurodegenerative disorder, which leads to the wasting of muscles over time and is usually diagnosed in infancy or early childhood. Prenatal Treatment for Spina ...read more
