Hidden for Centuries Near Machu Picchu, an Ancient System of Unknown Inca Roadways Has Resurfaced

According to a report by The Debrief, a Polish-Peruvian research team using drone-mounted LiDAR technology discovered over 1.6 miles of previously unknown Inca roadways near Peru’s Machu Picchu National Archaeological Park. Led by Bartłomiej Ćmielewski, Jeff Rocky Contreras Soto, and Prof. Mariusz Ziółkowski, the survey revealed roads, platforms, and terraces across the Urubamba Valley near the Mandor Wall. Researchers state these findings provide new evidence of Inca activity on the opposite bank of the valley. The team plans further remote-sensing and partial excavations through 2027 to veri

This Unusual “Rogue DNA” Allows Some Cancers to Thrive—and Scientists Just Found Its Achilles’ Heel

According to a study published in Nature by Memorial Sloan Kettering Cancer Center researchers, extrachromosomal DNA (ecDNA)—which drives growth in roughly one in six human cancers—possesses a built-in fragility at repetitive TA structures. The team observed that cancer cells rely on proteins FANCM and Polθ to repair these fragile points. Inhibiting Polθ with experimental drugs destabilized ecDNA across prostate, gastric, and colorectal cancer cell lines while sparing normal cells. Although Polθ inhibitors are in clinical development, researchers stress that further studies are necessary befor

South Korean Soldiers Were Searching for Landmines—They Found a Centuries-Old Weapon Instead

South Korean soldiers conducting landmine clearance operations near Mount Geumseong discovered the earliest known Korean firearm, identified as a Hwangja Hwatong (Yellow-Character Hand Cannon). According to the National Naju Research Institute of Cultural Heritage, preliminary research indicates the 10-inch bronze artifact likely dates to either 1377 or 1437, periods marked by Goryeo Dynasty gunpowder development or King Sejong's artillery standardization. Inscriptions detail its production official and maker.

When Magenta Solar Panels Were Placed Above Growing Broccoli Something Unexpected Happened

Researchers at Mälardalen University in Sweden tested semi-transparent magenta solar panels placed over broccoli crops to balance electricity generation with agricultural growth. According to lead author Silvia Ma Lu, the broccoli grown beneath the prototype panels demonstrated a 4.5-fold increase in light-use efficiency and produced crop yields similar in size to open-sunlight control plots. However, the covered plants required an additional 25 days to reach maturity. The team emphasized that these early findings reflect specific experimental conditions and require broader validation across d

“A Final Pathway for Reducing Anxiety”: If Smoking Cannabis ‘Stresses’ You Out, This Might Be Why

Northwestern University researchers led by Dr. Sachin Patel identified specific brain neurons that escalate stress and anxiety following cannabis consumption, particularly during stressful events. In experiments with laboratory mice exposed to synthetic cannabinoids and a predator scent, researchers observed increased fear behaviors. Brain imaging revealed that cannabinoids weakened the natural brake on somatostatin neurons in the central amygdala, amplifying fear responses. The study provides a scientific mechanism for why cannabis can exacerbate anxiety in stressful conditions and suggests t

Your gut may be making a molecule that raises Alzheimer’s risk

According to a report published by ScienceDaily, scientists have linked a gut bacterial compound known as ImP to an elevated risk of Alzheimer’s disease. The compound is associated with harmful protein buildup in the brain and faster cognitive decline. This finding highlights the potential that reducing blood levels of ImP could eventually help prevent or slow dementia progression. However, this relies on a brief excerpt, so further details regarding methodology, trial phases, and mechanisms remain unspecified.

A Mysterious Life-Sized Carving in Sudan Has Long Baffled Researchers—Now Its Secret History Could Finally Be Revealed

According to a report by The Debrief on a study published in Antiquity, researchers led by Dr. Joanna A. Ciesielska of the University of Warsaw have uncovered new context regarding a life-sized granite petroglyph in Miseeda, Sudan. The ancient figure, incorporated into a seventh-century Christian church site, may depict an ancient Kushite king or Nubian ruler marking a historic borderland, drawing comparisons to a carving at Gebel Qeili. However, researchers emphasize that the exact age and identity of the figure remain unknown, requiring additional investigation to confirm their hypotheses.

James Webb Telescope Uncovers New Evidence of Cosmic Collisions—and One of Them May Have Created Our Moon

According to a report by The Debrief, astronomers led by Kate Su used NASA's James Webb Space Telescope and Spitzer Space Telescope to analyze over 20 extreme debris disks around distant stars. The team identified two mineral categories in the dusty environments: silica-rich disks, indicating massive energetic collisions between Mars-sized bodies, and silica-poor disks, suggesting less energetic impacts. Su and coauthor Agnes Kospal noted that the silica-rich disks, found around stars younger than 300 million years, offer potential insights into early planetary evolution and hypotheses like th

Ancient Sea Level Analysis Reveals Earth’s Land Masses ‘Moved Rapidly’ Over 320 Million Years

Researchers from the University of Oslo’s Centre for Planetary Habitability report that Earth experienced rapid episodes of "true polar wander" (TPW) over the past 320 million years, particularly during the Jurassic and Cretaceous periods. By analyzing global continental flooding patterns and sea-level shifts, the team identified distinct TPW signals that challenge the traditional view of TPW as consistently slow or negligible. The study corroborates earlier paleomagnetic suggestions of episodic shifts while finding little evidence for competing hypotheses regarding Cenozoic TPW or Pangea's ra
