Hunter-gatherers at Poverty Point may have built its massive earthworks not under the command of chiefs, but as part of a vast, temporary gathering of egalitarian communities seeking spiritual harmony in a volatile world. New radiocarbon data and reexamined artifacts suggest far-flung travelers met to trade, worship, and participate in rituals designed to appease the forces of nature. Read more ›

Participants lost more weight on a low-fat vegan diet than on the Mediterranean diet, largely due to eliminating animal foods and reducing oils and nuts. Increased intake of plant foods, even “unhealthy” ones, was strongly associated with greater weight loss. Read more ›

Scientists are uncovering what makes some carcinomas so resistant: their ability to change identity. Two new studies reveal crucial proteins and structures that could become targets for future therapies. These discoveries deepen understanding of how tumors reprogram themselves and point toward highly specific treatments. The work raises hopes for safer, more selective cancer drugs. Read more ›

Hypertension begins harming the brain surprisingly early, even before measurable blood pressure increases. Key cells related to blood vessels, signaling, and myelin maintenance begin aging prematurely and malfunctioning. These disruptions resemble early patterns seen in cognitive decline and Alzheimer’s. Encouragingly, losartan reversed some of this early damage in mice. Read more ›

A research team has found that specific immune cells can connect with muscle fibers in a lightning-fast, neuron-like way to promote healing. These cells deliver quick pulses of calcium, triggering repair within seconds. The mechanism works in both injury and disease models. The discovery could inspire new treatments for muscle recovery and degeneration. Read more ›

Sargassum seaweed is creating major new obstacles for sea turtle hatchlings, drastically slowing their crawl to the ocean and increasing their risk from predators and heat. Despite the physical challenge, their energy stores stay stable, suggesting the real danger lies in the delay itself. Read more ›

UC Davis researchers engineered wheat that encourages soil bacteria to convert atmospheric nitrogen into plant-usable fertilizer. By boosting a natural compound in the plant, the wheat triggers bacteria to form biofilms that enable nitrogen fixation. This breakthrough could cut fertilizer use, reduce pollution, and increase yields. It also offers huge potential savings for farmers worldwide. Read more ›

A massive long-term study shows that Mediterranean and plant-based diets can help prevent chronic constipation in aging adults. Surprisingly, the benefits weren’t explained by fiber alone. Western and inflammatory diets raised constipation risk, while low-carb diets showed minimal impact. The research underscores how diet quality influences gut health well beyond traditional advice.

Ultra-processed foods are rapidly becoming a global dietary staple, and new research links them to worsening health outcomes around the world. Scientists say only bold, coordinated policy action can counter corporate influence and shift food systems toward healthier options. Read more ›

Researchers have uncovered a surprising new role for the HSL protein: beyond breaking down fat, it also works inside the nucleus of fat cells to keep them functioning properly. When HSL is missing, fat tissue doesn’t expand as expected— instead, it shrinks, leading to lipodystrophy. This unexpected discovery helps explain why both obesity and fat-loss disorders share similar health risks, and it opens up fresh paths for understanding metabolic diseases... Read more ›

A Swedish plano-convex ingot once thought to be from the Bronze Age was revealed through chemical and isotopic testing to belong to the Iron Age. Its composition closely matches Iron Age finds from Poland, leading researchers to uncover new evidence of long-distance connections across the Baltic. The study highlights how collaboration and scientific analysis can transform isolated artifacts into clues about ancient trade and networking. Read more ›

Monk parakeets ease into new friendships, slowly approaching strangers to avoid aggressive encounters. Researchers watched how birds shared space, groomed each other, and escalated to deeper social bonds over time. The results show a clear pattern of cautious exploration echoing similar studies in other animals. Even for birds, making a friend can be a delicate dance. Read more ›

About 4.5 billion years ago, a colossal impact between the young Earth and a mysterious planetary body called Theia changed everything—reshaping Earth, forming the Moon, and scattering clues across space rocks. By examining subtle isotopic fingerprints in Earth and Moon samples, scientists have reconstructed Theia’s possible composition and birthplace. Read more ›

Scientists have uncovered how leukemia cells manage to escape one of the most commonly used treatments. Over time, these cancer cells subtly change the shape of their mitochondria to avoid dying when the drug tries to kill them. By identifying the protein that controls this shape-shifting, researchers were able to block it in mice, making the treatment powerful again and dramatically extending survival. Read more ›

Researchers have uncovered a surprising way the brain switches pain on, revealing that neurons can release an enzyme outside the cell that activates pain signals without disrupting normal movement or sensation. This enzyme, called VLK, modifies nearby proteins in a way that intensifies pain and strengthens connections tied to learning and memory. Removing VLK in mice dramatically reduced post-surgery pain while leaving normal function untouched, offering a promising path toward... Read more ›

Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at different points, researchers can now watch damage flare up, track repair proteins rushing to the site, and see the moment the DNA is restored. Built from a natural protein that binds gently and briefly to damaged DNA, the sensor offers... Read more ›

Researchers discovered that raising the protein Sox9 can help the brain’s astrocytes clear out toxic plaque buildup linked to Alzheimer’s. In mouse models that already showed memory problems, activating these cells improved cognitive performance. The treatment also reduced plaque levels over time. The work points toward a natural, cell-based way to slow Alzheimer’s decline. Read more ›

Ideas about Vikings and Norse mythology come mostly from much later medieval sources, leaving plenty of room for reinterpretation. Over centuries, writers, politicians, and artists reshaped these stories to reflect their own worldviews, from romantic heroism to dangerous nationalist myths. Pop culture and neo-paganism continue to amplify selective versions of this past. Scholars today are unraveling how these shifting visions emerged and how they influence identity and culture.

Scientists flew the XL-Calibur telescope on a high-altitude balloon to measure polarized X-rays from Cygnus X-1. These measurements reveal details about the chaotic, superheated material swirling around black holes. The team also captured data from the Crab pulsar and achieved multiple technical breakthroughs during the 2024 mission. Another flight from Antarctica is expected to expand this cosmic investigation.
