This cancer-fighting molecule took 50 years to build

16:56
MIT scientists have achieved the first-ever lab synthesis of verticillin A, a complex fungal compound discovered in 1970. Its delicate structure stalled chemists for decades, despite differing from related molecules by only two atoms. With the synthesis finally complete, researchers created new variants that showed strong activity against a rare pediatric brain cancer. The breakthrough could unlo…

Why evolution rewarded ants that sacrificed protection

15:11
Some ants thrive by choosing numbers over strength. Instead of heavily protecting each worker, they invest fewer resources in individual armor and produce far more ants. Larger colonies then compensate with collective behaviors like group defense and coordinated foraging. The strategy has been linked to evolutionary success and greater species diversity.

A new drug could stop Alzheimer’s before memory loss begins

14:36
New research suggests Alzheimer’s may start far earlier than previously thought, driven by a hidden toxic protein in the brain. Scientists found that an experimental drug, NU-9, blocks this early damage in mice and reduces inflammation linked to disease progression. The treatment was given before symptoms appeared, targeting the disease at its earliest stage. Researchers say this approach could r…

Why one long walk may be better than many short ones

14:36
How you walk may matter just as much as how much you walk. A large UK study tracking more than 33,000 low-activity adults found that people who grouped their daily steps into longer, uninterrupted walks had dramatically lower risks of early death and heart disease than those who moved in short, scattered bursts.

This simulation reveals what really happens near black holes

11:42
Black holes are among the most extreme objects in the universe, and now scientists can model them more accurately than ever before. By combining Einstein’s gravity with realistic behavior of light and matter, researchers have built simulations that closely match real astronomical observations. These models reveal how matter forms chaotic, glowing disks and launches powerful outflows as it falls i…

Subaru Telescope reveals a hidden giant planet

10:31
Astronomers have uncovered a massive hidden planet and a rare “failed star” by combining ultra-precise space data with some of the sharpest ground-based images ever taken. Using the Subaru Telescope in Hawaiʻi, the OASIS survey tracked subtle stellar wobbles to pinpoint where unseen worlds were lurking—then captured them directly.

This AI finds simple rules where humans see only chaos

8:20
A new AI developed at Duke University can uncover simple, readable rules behind extremely complex systems. It studies how systems evolve over time and reduces thousands of variables into compact equations that still capture real behavior. The method works across physics, engineering, climate science, and biology. Researchers say it could help scientists understand systems where traditional equati…

Parkinson’s breakthrough changes what we know about dopamine

8:20
A new study shows dopamine isn’t the brain’s movement “gas pedal” after all. Instead of setting speed or strength, it quietly enables movement in the background, much like oil in an engine. When scientists manipulated dopamine during movement, nothing changed—but restoring baseline dopamine levels made a big difference. The finding could reshape how Parkinson’s disease is treated.

A traditional Brazilian plant shows unexpected strength against arthritis

7:14
A Brazilian study has confirmed that Joseph’s Coat, a plant used for generations in folk medicine, can significantly reduce inflammation and arthritis symptoms in lab tests. Researchers observed less swelling, healthier joints, and signs of tissue protection. Just as important, the extract showed a promising safety profile at tested doses. The discovery could pave the way for new plant-based anti…

Study links full-fat cheese to lower dementia risk

22.prosince
Eating full-fat cheese and cream may be associated with a lower risk of dementia, according to a large study that tracked people for more than 25 years. Those who consumed higher amounts of these foods developed dementia less often than those who ate little or none. Interestingly, low-fat dairy products did not show the same pattern. Researchers caution that the findings show an association, not …

Global warming could trigger the next ice age

22.prosince
Scientists have uncovered a missing feedback in Earth’s carbon cycle that could cause global warming to overshoot into an ice age. As the planet warms, nutrient-rich runoff fuels plankton blooms that bury huge amounts of carbon in the ocean. In low-oxygen conditions, this process can spiral out of control, cooling Earth far beyond its original state. While this won’t save us from modern climate c…

Hidden seismic signals hint at a tsunami threat in Alaska

21.prosince
Researchers studying a massive landslide in Alaska have detected strange seasonal seismic pulses caused by water freezing and thawing in rock cracks. These faint signals could become an important early clue to changes that might someday trigger a dangerous landslide-driven tsunami.

Ancient sewers expose a hidden health crisis in Roman Britain

21.prosince
Sediments from a Roman latrine at Vindolanda show soldiers were infected with multiple intestinal parasites, including roundworm, whipworm, and Giardia — the first time Giardia has been identified in Roman Britain. These parasites spread through contaminated food and water, causing diarrhea, weakness, and long-term illness. Even with sewers and communal toilets, infections passed easily between s…

Science says we’ve been nurturing “gifted” kids all wrong

21.prosince
A major international review has upended long-held ideas about how top performers are made. By analyzing nearly 35,000 elite achievers across science, music, chess, and sports, researchers found that early stars rarely become adult superstars. Most world-class performers developed slowly and explored multiple fields before specializing. The message is clear: talent grows through variety, not narr…

A new tool is revealing the invisible networks inside cancer

21.prosince
Spanish researchers have created a powerful new open-source tool that helps uncover the hidden genetic networks driving cancer. Called RNACOREX, the software can analyze thousands of molecular interactions at once, revealing how genes communicate inside tumors and how those signals relate to patient survival. Tested across 13 different cancer types using international data, the tool matches the p…
