NASA Unveils Sinister Eyes in Space, and They Seem to Be Staring Right at You

Astronomy, Planetary Science / Marcílio Santos

Abyss Gazing Back: Nietzsche’s Prophetic Words in Space “The abyss also looks back into you,” said German philosopher Friedrich Nietzsche in 1886. His words feel almost prophetic as we gaze, nearly 140 years later, at an image from 80 million light-years away that resembles a pair of piercing eyes, staring back at us. In reality, […]

Link Between Gut Inflammation and Alzheimer’s Disease Reconfirmed

Healthcare, Medicine / Ana Kiesse Zeleme

Researchers are piecing together the complex relationship between gut health and Alzheimer’s disease, revealing yet another connection between our digestive system and brain function. Animal studies have shown that gut microbes can transmit Alzheimer’s to young mice, reinforcing this link. Furthermore, a 2023 study supports the idea that inflammation may be the mechanism behind this

Health Authorities Uncover Banned Chemicals in Multiple Cosmetic Products

Healthcare, Medicine / Mauro Lucas

The European Chemicals Agency (ECHA) reported on Wednesday that it had identified hazardous, banned chemicals in hundreds of cosmetic products sold throughout Europe. Moreover, the Helsinki-based agency inspected nearly 4,500 cosmetic products across 13 European countries, discovering that six percent—or 285 products—contained substances prohibited for their harmful health effects. Hazardous Chemicals Found Across a Range

Nobel Prize in Physics: How Hopfield and Hinton’s AI Transformed Our World

Physics / Marcílio Santos

If you’ve enjoyed an AI-generated video, fraud protection, or voice-to-text, you can thank scientists like physicist John Hopfield and computer scientist Geoffrey Hinton. On Oct. 8, 2024, they received the Nobel Prize in Physics for their pioneering work on artificial neural networks, which, though inspired by biology, relied heavily on statistical physics. How neurons compute

A Million Were Struck by This Mysterious Disease Before It Vanished

Healthcare, Medicine / Valeriano Ndeyi

In the film Awakenings, Robert De Niro’s character laments, “People have forgotten what life is all about” after he revives from a 30-year shutdown state. This film, based on Dr. Oliver Sacks’ true story, explores the lives of individuals impacted by encephalitis lethargica, or “sleepy sickness.” Far from rare, this disease affected over a million

Microbes Found Alive Sealed in Rock For 2 Billion Years

Microbiology, Science / Mauro Lucas

Deep underground, a community of microbes has thrived in isolation for billions of years. These organisms, found in 2 billion-year-old rock, have been cut off far longer than any known subterranean microbes, surpassing the previous record of 100 million years. Geomicrobiologist Yohey Suzuki from the University of Tokyo finds this discovery very exciting. He notes

Scientists Observe Sperm Defying a Fundamental Law of Physics

Biology, Cell Biology / cumbonguala

According to a recent study, human sperm use their slender tails to navigate through thick fluids, appearing to defy Newton’s third law of motion. This research also examines the movement patterns of these sex cells alongside single-celled algae. Exploring Non-Reciprocal Interactions in Microscopic Swimmers Kenta Ishimoto, a mathematical scientist at Kyoto University, and his team

Feeling Sleepy? Research Identifies the Best Dosage and Timing for Melatonin

Healthcare, Medicine / Jorge Paka

Melatonin is a well-known supplement for individuals who have difficulty achieving restful sleep. However, determining the right dosage and the ideal time to take it has often involved trial and error. A recent study addresses this uncertainty. The Role of Melatonin in Sleep Regulation and the Impact of Digital Devices When melatonin levels increase in

Large Study Reveals Unexpected Origins of Gout

Healthcare, Medicine / Eduardo Paulo

Gout is often linked to poor diet and drinking habits, but new research reveals genetics as a stronger factor in developing the condition than previously believed. In a major study, researchers analyzed genetic data from 2.6 million individuals, including 120,295 with this disease, identifying 377 DNA regions associated with the condition—149 of which were new.

Scientists Finally Uncover What Really Happens When an Atom Splits

Experimental Physics, Physics / Marcílio Santos

The term “atom,” derived from Latin for “indivisible,” can be misleading. A recent simulation by U.S. theoretical physicists has provided a detailed microscopic view of how an atom splits in two, shedding light on an energetic event that has significantly impacted science and technology. In 1938, physicists Otto Hahn, Lise Meitner, and Fritz Strassmann demonstrated
