Scientists find new markers to identify species from fossilized bone fragments
Credit: Pixabay/CC0 Public Domain What happened to all the Megafaunas? Many large animals, from more to mammoths, went extinct 50 to 10,000 years ago. Provide important evidence about prehistoric ecosystems and learn why it can help you understand future potential extinctions. However, surviving fossils are often too fragmented to determine the original species, and DNA is not always resilient, especially…

SWOT satellites find large river waves for the first time
The SWOT satellite is helping scientists size flood waves in waterways like the Yellowstone River painted in Montana in October 2024. SWOT measures surface water heights, including the oceans, and hundreds of thousands of rivers, lakes and reservoirs in the United States alone. Credit: NP First, researchers at NASA and Virginia Tech used satellite data to measure the height and…

Lower the starlight and find a new exoplanet
To capture images of starless exoplanets, the new coronagraph design uses a mode sorter to separate and remove light from the stars and to reconstruct the optical field after rejecting starlight. Credit: University of Arizona Nico Deschler Researchers have developed a new coronagraph, an optical device that blocks light from bright sources. The new device can reveal exoplanets beyond the…

Scientists find evidence that they challenge the theory of the origin of water on Earth
The metstone used in this study was when it was used when it was discovered in Antarctica. Credits: Ansmet (Meteorite Antarctic Search) Program, Case Western Reserve University, University of Utah. A team of researchers at Oxford University reveals important evidence regarding the origin of water on Earth. Using a rare type of metite stone known as enstatite chondrites, which have…

Monkeys are the best yoderers in the world, find “voice break” analysis
Black and gold Haurasal (Alouatta Caraya). Credit: Dr. Jacob Dunn, Anglia Ruskin University New research has found that the world’s most incredible yodelers are not from Austria or Switzerland, but from the tropical rainforests of Latin America. Published in the Journal Philosophical Transactions of the Royal Society B and led by experts from Anglia Ruskin University (ARU) and the University…

Antarctic Scientists: Why They Are There, and What They Find
Credit: Unsplash/CC0 Public Domain A media storm exploded in mid-March 2025 when researchers at an isolated Sanae IV base in South Africa accused one of nine team members of being violent. Conversation Africa asked David William Heading, a geomorphologist who has previously done research from the frozen continent, about the work that researchers do in Antarctica, what situations and what…

Astronomers find gas exoplanets that have formed earlier than previously thought
Credit: Unsplash/CC0 Public Domain New research shows that a new look at past data reveals that a tumor with a Jupiter-like mass formed much earlier than previously thought. The results of the Ohio State University survey provide new information on the timing of accumulation. This is the process of accumulating large amounts of gases and solid particles rich in carbon…

Physicists find unexpected electron crystals in new ultra-thin materials
This graphic visualizes how electrons behave as solids (left, glacier-like structure) or liquids (river-like structures) depending on the voltage applied to new material cooled to ultra-low temperatures similar to space. Credits: Michael Hurley and Sampson Wilcox/Research Laboratory of Electronics MIT physicists report the unexpected discovery of electrons forming crystal structures in a material that is a billionth of thickness. This…

Sulfur may be a new tool to find alien life
A cartoon depiction of the sulfur cycles in various planetary regimes. In the case of Earth (a), the atmosphere so2 is scrubed from the atmosphere due to wet deposition. For example, in cases like Venus with UV irradiation (B), SO2 is abundant in deep atmosphere, such as by the sun. However, in the upper atmosphere, SO2 is efficiently catalyzed by…

Efforts to find an alien life can be boosted by simple tests that drive microorganisms
Credit: Pixabay/CC0 Public Domain Finding life in space is one of the great efforts of humanity. One approach is to find motile microorganisms that can move independently. This is an ability that is a strong hint in life. When movement is induced by a chemical and the organism moves accordingly, it is known as chemotactic. Currently, German researchers are developing…
