Perseverance has traveled almost 26 miles on Mars—nearly a marathon

After more than five years on Mars, Perseverance has covered almost 26 miles (42 kilometers), just shy of the official marathon distance of 26.2 miles, while collecting 27 rock cores and abrading 62 rocks.

People Judge Faces Within Milliseconds

Research suggests that humans begin forming impressions of trustworthiness, competence, and attractiveness within a fraction of a second after seeing a face. These judgments often occur automatically and can influence decisions even when people believe they are being objective.

The Brain Often Makes Decisions Before You're Aware of Them

Experiments measuring brain activity have found signals indicating a person's choice several seconds before they consciously report making that decision. While scientists still debate what this means for free will, the findings suggest that some decision-making processes begin unconsciously before entering conscious awareness.

Antarctica holds 70% of Earth's freshwater and 90% of its ice in a single massive ice sheet.

The Antarctic ice sheet spans over 30 million cubic kilometres, making it by far the largest on the planet. Its thickness and movement are tracked by satellites, as changes there have global impacts on sea levels and ocean currents.

Many Ice Creams Contain Ingredients Derived from Seaweed

A surprising number of commercial ice creams contain carrageenan, a natural thickening agent extracted from red seaweed. Manufacturers use it to improve texture, prevent ice crystal formation, and create a smoother mouthfeel. While most consumers never notice it on ingredient labels, seaweed-derived additives have been used in food production for decades and can be found in everything from dairy products to plant-based alternatives.

6. Apples Turn Brown Because of Their Own Defense Mechanism

When an apple is sliced or bruised, its cells rupture and expose enzymes to oxygen in the air. These enzymes trigger a chemical reaction that produces brown pigments on the fruit's surface. While many people assume browning is a sign of spoilage, it is actually part of the apple's natural defense system. The reaction helps protect damaged tissue from microbes and insects by creating compounds that are less appealing to potential threats. Some research suggests the quinone compounds produced during browning may help deter insects and inhibit certain microbes, though scientists continue to study the extent of this defensive role.”

A day on Earth is getting longe

The Moon's gravity gradually slows Earth's rotation. Hundreds of millions of years ago, a day lasted only about 22 hours.

Earth's magnetic poles have reversed hundreds of times

The north and south magnetic poles have switched places many times throughout Earth's history. The last major reversal occurred about 780,000 years ago.
