The history of human settlement in North America is altered by footprints.
At White Sands, New Mexico, researchers found human footprints preserved in prehistoric mud. These footprints seem to be from the Last Glacial Maximum (LGM), which occurred around 23,000 years ago during the last Ice Age, when glaciers were at their greatest.

Ancient life may have existed in Mars' clay layers.
One of the most fascinating geological mysteries of the Red Planet is the existence of thick, planet-wide clay sheets. Scientists have long considered these deposits to be possible time capsules for ancient life because clay only forms when there is an abundance of liquid water present.

'Ice 0' is a novel and uncommon kind of ice that scientists have discovered.
Water rarely behaves as casual observers would expect. Cooling the pond at night, he becomes hard from top to bottom, but when expanded enough, the story becomes much more complicated. Scientists have catalogued more than 20 different ice ports, each formed under a specific temperature and pressure combination. The familiar hexagonal variety that turns into snowflakes is just one chapter in a much thicker book.

Researchers find a secret that has existed for 1.3 billion years in Earth's greatest iron ore deposits.
Although steel is the foundation of contemporary life, the iron that supports it has a much longer history than the first nail. For many years, geologists believed that the largest and richest iron ore resources in the world were produced around 2.2 billion years ago, just after breathable oxygen began to permeate the Earth's atmosphere.

Worldwide, a deadly fungus that can "eat you from the inside out" is rapidly expanding.
Imagine a daily exposure to hundreds of invisible spores. The majority drift in and out of our airways undetected. However, some of those spores are associated with moulds that are intolerant of borders.

The world's most dangerous animals can be effectively killed by cannabis extract.
More than a million lives are lost to mosquito-borne illnesses worldwide each year, surpassing all other animal threats to humankind. Public health teams are frantically searching for new weapons in response to the growing death toll, particularly as conventional chemical sprays become less effective.

To maintain your memories in sequence, the human brain employs a storage technique.
For decades, researchers have been baffled by the brain's memory storage mechanism. How our minds can store new knowledge without erasing what we already know has long been a mystery. Following a thorough examination, scientists have discovered that place cells contain crucial hints about this process.

Radio transmissions from SpaceX's Starlink satellites are leaking, endangering astronomy.
At the frequencies that radio telescopes value most, space is typically quiet. However, over the past two years, researchers searching for hints from the young universe have been hearing radio signals from SpaceX's Starlink fleet, a noisy new neighbor

Scientists believe they now understand why bats do not develop cancer.
German shepherds shouldn't be outlived by tiny creatures weighing less than one ounce, but many bats do. In the wild, some even live for almost 35 years, which is equivalent to 180 human years and is accompanied by an incredible lack of tumours.

Unknown radio waves that "defy physics" are emanating from deep beneath the Antarctic ice.
Antarctica has some of the world's clearest skies, which makes it the ideal location for eavesdropping on the universe. The Antarctic Impulsive Transient Antenna, or ANITA, is carried by a NASA balloon that hovers far above the continent. When ultra-energetic cosmic rays strike the atmosphere, radio murmurs are captured by the ANITA experiment.
