Ancient Maya civilization purified water using filtration system made of crystal minerals
Researchers from the University of Cincinnati discovered that the Ancient Maya likely had a sophisticated water purification system made of quartz and zeolite, a non-toxic crystalline compound composed of silicon and aluminum. The researchers uncovered the minerals in the Corriental reservoir, a major source of drinking water for the Mayans who lived in what is now northern Guatemala. In an article published […]

Meteorite in Michigan may hold clues to origin of life on Earth
According to a new study a meteorite that fell in Michigan in 2018 may contain clues to the origin of life on Earth. Published in the journal Meteoritics & Planetary Science, the study said that the meteorite contained a good amount of organic matter. Researchers from the U.S., Canada, Germany and China were able to pick up and examine […]

Tough tardigrades: Microscopic water bears can withstand harmful radiation, thanks to a certain protein
A protein found only in tardigrades may protect cells from DNA damage caused by radiation exposure, according to a recent study published in eLife. Researchers from the University of California, San Diego examined the protective properties of a damage-suppressing protein called Dsup and found that it has a cloud-like structure that shields cell components from free radicals. According to coauthor James Kadonaga, […]

North Atlantic right whales “whisper” to protect young calves from predators
A recent study published in Biology Letters found that North Atlantic right whales produce “whisper-like sounds” when communicating with their calves to avoid attracting predators. Researchers from Syracuse University, Duke University and the National Oceanic and Atmospheric Administration observed that the mothers dramatically toned down an “up call,” which right whales use to communicate with each other, when communicating to their young. […]

NASA confirms water on sunlit areas of the moon
A study published Monday in the journal Nature Astronomy has confirmed the existence of water on the sunlit surface of the moon. This discovery indicates that water may be distributed throughout the lunar surface and not limited to the deep, shadowed craters in the lunar south pole. Using the National Aeronautics and Space Administration (NASA) telescope aboard the […]

Paleolithic prepping: Prehistoric humans stocked up on food by serving marrow-filled bones as “canned” soup
Spanish and Israeli researchers have found evidence suggesting that ancient humans stored marrow-filled bones for later consumption. 400,000 years ago, these ancient humans enjoyed these much like one would enjoy a can of soup, using the bone and dried skin to preserve the fat and nutrient-rich bone marrow. These findings, published in the journal Science Advances, provide the earliest clues to food […]

The language of Nature: Plants communicate with each other to send alerts about incoming pests
When they’re under attack, plants send warning signals, says a recent study published in Current Biology. These signals come in the form of airborne natural chemicals, called volatile organic compounds (VOCs), which alert neighboring plants to a threat. But this is not merely an altruistic act, suggested researchers. It’s mutually beneficial as the receiving plants also emit these […]

Icy water detected in fresh moon craters may have several sources, suggest scientists
Researchers from Brown University and the National Aeronautics and Space Administration (NASA) found that the icy water in the moon may have sources besides volcanism and meteorites. In a study published in the journal Icarus, the researchers revealed that the ice deposits in some of the moon’s south pole craters formed relatively recently, suggesting other processes must be involved. Icy […]

The longest trail of fossilized footprints hints at an ancient woman and child’s dangerous trek in the wild
Researchers from the U.S. and the U.K. have uncovered the longest fossilized trackway made by man. Discovered in 2018, the trail of footprints stretches nearly a mile in what’s now the White Sands National Park in New Mexico. The team suggests that the trail was left by a woman carrying a toddler as they rushed across a muddy lakebed some […]

Shorebird breaks record for non-stop flight after flying from Alaska to New Zealand
A bar-tailed godwit breaks the world record for the longest shorebird flight after flying 75,000 miles nonstop. The male bird, which was named “4BBRW” for the blue, red and white rings on its legs, set off from Alaska on Sept. 16. It traveled eleven consecutive days before arriving in New Zealand. Scientists with the Global Flyway Network, a group of researchers who monitor migratory […]
