It shows that fitter people actually use fewer total heartbeats each day thanks to their lower resting heart rates, even when accounting for workouts. Athletes’ hearts beat around 10% less daily, saving over 11,000 beats per day compared to sedentary people. This efficiency not only signals cardiovascular fitness but also translates to longer life expectancy and lower disease risk.

Its integrated diffraction and data preparation modules enable unprecedented speed and efficiency for AI tasks. Demonstrations in imaging and trading showed improved accuracy, lower latency, and reduced power demand. This innovation pushes optical computing toward real-world, high-performance AI.

Scientists from the University of Sydney and Universidad Europea found that even people who walk less than 8,000 steps daily can see major heart health benefits simply by changing how they walk. Those who took their steps in one or two continuous sessions had lower rates of heart attacks, strokes, and death.

This tectonic shift reduced volcanic carbon emissions, expanded shallow seas, and boosted oxygen availability. Far from a stagnant era, Earth’s “Boring Billion” was a time of crucial transformation that made the planet more habitable. The study links deep-Earth movements directly to the rise of eukaryotic life.

In some blood cancers, damaged genes trigger chaos in these DNA segments, leaving cancer cells vulnerable. When scientists used existing drugs to block the cells’ repair systems, the cells collapsed. This finding could open the door to new treatments for hard-to-treat cancers.

At UCSF, neuroscientist Jennifer Mitchell is testing a pharmaceutical form of LSD called MM120, which has shown striking results in reducing symptoms by promoting neuroplasticity and easing rigid thought patterns. In clinical trials, a single dose significantly outperformed standard treatments, offering hope to those who have found little relief elsewhere.

Early communities harnessed predictable tides for irrigation, but when deltas cut off the Gulf’s tides, they faced crisis and reinvented their society. This interplay of environment and culture shaped Sumer’s myths, politics, and innovations, marking the dawn of civilization.

The new 3D seismic data reveals astonishing details about the violent minutes following impact—towering tsunamis, liquefied rock, and shifting seabeds. Researchers call it a once-in-a-lifetime look at how oceanic impacts unfold.

Despite models predicting a decline, researchers found that freshening surface waters are currently keeping deep CO2 trapped below. This stratification effect may be only temporary, as intensifying winds bring deep, carbon-rich water closer to the surface. If mixing increases, the Southern Ocean could begin releasing more CO2 than it absorbs.

The study followed thousands of adults for two decades, linking poor oral health with major cardiovascular events. Regular dental checkups dramatically reduced these risks, hinting that simple oral care could play a vital role in stroke prevention.

The study challenges the idea that gluten itself is the culprit behind symptoms in non-coeliac gluten sensitivity. Experts call for better diagnostic tools, more personalized treatment, and an end to unnecessary gluten avoidance.

Researchers found that species losses peaked about a century ago and have decreased since, with different drivers shaping past and present threats. Whereas invasive species once caused most island extinctions, habitat destruction now looms largest on continents.
