An NIH study found that women with high levels of two common “forever chemicals” had up to 93% higher rates of an aggressive form of breast cancer. The discovery raises concerns about the potential health effects of persistent chemicals found in everyday products.

Earth's water may have been born in the planet's fiery atmosphere rather than delivered by icy comets or asteroids. Scientists discovered that rocky pebbles reacting with hydrogen under extreme heat can produce water in minutes, potentially generating hundreds of oceans' worth during Earth's formation. The findings suggest that water may be a natural part of how rocky planets form, rather than so…

Scientists have uncovered a surprising way that fructose, a sugar commonly found in sweetened foods and drinks, may help aggressive ovarian cancer spread. Researchers discovered that cancer cells surviving chemotherapy release fructose that weakens the bonds holding neighboring tumor cells together, making it easier for cancer to spread. High dietary fructose levels and cholesterol-lowering stati…

A surprising new study suggests that walking, jogging, and even traditional weight training may be less effective at stimulating bone formation than high-intensity sports involving explosive movements and sudden changes in direction. Researchers found that activities such as football and handball increased markers of bone formation by up to 46%, potentially revealing a better way to protect bones…

A groundbreaking new supercomputer simulation is revealing how the universe escaped its cosmic dark age and transformed into a cosmos filled with stars and galaxies. Called Lumina, it recreates 2 billion years of early cosmic history across a region 1.6 billion light-years wide, capturing extraordinary details that previous simulations could not.

Researchers have created a quantum computer that stores information in microscopic vibrations, potentially making quantum machines smaller, more powerful, and better at preserving information. The breakthrough successfully demonstrated advanced quantum calculations and could help overcome major barriers to practical quantum computing.

NASA’s Parker Solar Probe has revealed a surprising secret hidden within the chaos of space: turbulent magnetic fields reverse their direction of rotation when examined at extremely small scales. The discovery exposes an unexpected pattern in solar wind turbulence that could help scientists better understand solar activity and predict geomagnetic storms.

Scientists have discovered that the first animals to venture onto land nearly 380 million years ago had surprisingly stiff necks, overturning a long-standing theory about evolution. Rather than evolving to help animals turn their heads, necks may have emerged as part of the anatomical changes that allowed them to move using their front limbs.

A remarkable discovery in a South African cave suggests that an extinct human relative may have created an all-female burial site more than 240,000 years ago. Scientists analyzed ancient proteins preserved in Homo naledi teeth and found no male-specific markers among at least 20 individuals, potentially solving a mystery that has puzzled researchers for over a decade.

The Antarctic ozone hole expanded to its seventh-largest size on record in 2026, driven by unusual weather conditions that pushed it close to its historic maximum. Scientists say international restrictions on ozone-destroying chemicals prevented even greater damage, and Earth's protective ozone layer is still recovering.

A new study found that energy drinks and stimulant supplements were linked to disproportionately frequent reports of serious heart problems, including 11 times more reports of cardiac arrest and 4.5 times more reports of heart attacks. Young adults accounted for nearly half of the cardiovascular reports involving these products, raising concerns about their potential risks despite the study being…

New research involving more than 440,000 Americans links cannabis use to increased cardiovascular risk, with occasional users showing 40% higher odds of reporting a history of stroke. The findings suggest that even infrequent marijuana use may warrant concern, although researchers have not established that cannabis directly causes strokes or heart disease.

Scientists have discovered that the intricate patterns of hair follicles on mammals may arise from a remarkably simple process involving cells following chemical signals. The findings challenge a long-standing theory and reveal how nature can create complex biological patterns without a detailed blueprint.

A surprising study of more than 4,500 older adults found that people who were overweight or obese when diagnosed with dementia had a 16% to 27% lower risk of death than those at a normal weight. Researchers suspect that extra energy and muscle reserves may help patients survive the disease's toll on the body, although the reason for the survival advantage remains unclear.

A bizarrely deformed 1834 British silver coin found at a car boot sale may preserve evidence of a rare minting accident nearly 200 years ago. Advanced 3D scans and microscopic analysis revealed unusual metal distortions suggesting the coin was crushed under extreme pressure, potentially during its original production.
