Popular sugar substitutes linked to faster brain aging
Several popular sugar substitutes may not be as harmless as they seem. Adults who consumed the most artificial sweeteners showed substantially faster declines in memory and thinking, especially if they were under 60 or had diabetes. The highest intake was linked to cognitive aging roughly 1.6 years faster than the lowest intake. Researchers stressed that more studies are needed before concluding that sweeteners are the cause.

A shattered asteroid may have bombarded Earth 800 million years ago
A catastrophic asteroid breakup may have triggered a huge wave of impacts across the inner solar system about 800 million years ago. The debris was launched from near a gravitational gateway controlled by Jupiter, sending fragments toward Earth, the Moon, and Mars. The bombardment may explain ancient lunar craters and could have contributed to major climate and biological changes on Earth.

Earth’s biggest volcanic event transformed an entire oceanic plate
Seismic waves have revealed that the oceanic plate beneath the Ontong Java Plateau was dramatically transformed by the colossal volcanic activity that created it more than 100 million years ago. Researchers found a complex structure of horizontal layers cut through by vast swarms of vertical magma channels, along with unusually slow seismic waves suggesting that deep-rising magma chemically altered the plate itself.

Intermittent fasting helped people keep weight off for a year
A 12-week intermittent fasting program produced weight-loss benefits that were still visible a year later. Participants who ate within an eight-hour window maintained more weight loss than those who followed their usual longer eating schedule. Both early and late eating windows worked, while early fasting appeared especially helpful for preserving fat loss.

Mediterranean diet may activate tiny proteins that protect the heart and brain
The Mediterranean diet may influence aging through tiny proteins produced inside the cell’s mitochondria. Older adults who followed the diet most closely had higher levels of humanin and SHMOOSE, which have been linked to heart and brain protection. Olive oil, fish, legumes, and fewer refined carbohydrates appeared especially important. The findings could eventually help scientists develop more personalized nutrition plans for healthy aging.
