A Newly Discovered Fossil Could Be The Answer to Darwin’s ‘Abominable’ Mystery

Scientists in China say they have found the oldest flower bud in a fossil record, finally reconcile fossil evidence with genetic data suggesting that flowering plants, or angiosperms, evolved tens of millions of years earlier than we initially thought. The team hopes their discovery will help “alleviate the pain” around a torturous, century-old mystery that … Read more

Fossil Analysis Reveals This Well-Armored Dinosaur Was Probably Sluggish And Deaf

Re-analyzing fossils can often lead to new discoveries, as was the case with the study of 80 million-year-old Late Cretaceous Struthiosaurus austriacus skull. A new analysis reveals that the dinosaur was probably sluggish in its movements, and was probably mostly deaf. The researchers used a high-resolution 3D scan of a partial portion of the meninges … Read more

Strong, Sporadic Magnetic Fields Could Explain One of The Moon’s Enduring Mysteries

It’s been half a century since the Apollo missions returned from the moon, and the lunar patterns they brought home continue to confuse us. Some of these rocks are more than 3 billion years old and appear to have formed in the presence of a strong geomagnetic field, such as that on Earth. But the … Read more

What Is The ‘Lunar Effect,’ And What Does It Have to Do With Shark Attacks?

When the full moon comes out, strange things can happen here on Earth. The oysters are getting closer. Corals are spawning. Dive the zooplankton deeper. Seabirds cling to the shore. And lions hunt less. Several of these behaviors are related to the moonlight; others, to the tide. But some have no clear explanation at all. … Read more

Perseverance Has Run Into a Problem on Mars: Pebbles

A small pile of pebbles interferes with the work of the Perseverance Mars rover. The rover, which is collecting rock samples for a possible return to Earth, began the ordeal on Dec. 29, after pulling a core out of a rock the mission team called “Issole.” According to a NASA blog, the problem occurred in … Read more

Pavlovian Experiments on Locusts Provide New Clues on How Smell Works in The Brain

From the smell of brewing coffee to the smell of rain soaking the soil, the distinction of smells is one of the reasons why the sense of smell is wonderful. But how our brain can understand smells like coffee, regardless of the season, place or time, is a complex question that needs to be answered. … Read more

This Ancient Peruvian Empire Put Hallucinogenics in Beer For Political Reasons

The ancient Wari empire in Peru may have used hallucinogenic beer to garner support in new territories. The remains of a large feast, found at the Wari outpost from the 9th century AD, strongly point to the seeds of a psychoactive plant called the fork (Anadenanthera colubrina) were once mixed with chicha, a beer made … Read more

Take a Look at The Largest And Most Detailed 3D Map of The Universe Ever Made

The Dark Energy Spectroscopic Instrument (DESI), currently aimed at the sky from its home at the Nicholas U. Mayall Telescope at the Kitt Peak National Observatory in Arizona, is tasked with plotting space expansion, exploring dark energy and creating the most detailed 3D space map ever compiled . It’s only been seven months of DESI’s … Read more

There’s a Hidden Mathematical ‘Law’ in The Sand Megaripples Found All Over Earth

Wherever there is sand and atmosphere, prevailing winds can whip the grains into wavy shapes, pleasing to the eye with their soothing repetition. Certain sand waves, with wavelengths between 30 centimeters (almost 12 inches) and a few meters (about 30 feet), are known as megaripples: they are the size between ordinary waves on the beach … Read more
