Cosmic rays turned ancient sand into a geological time machine

Curtin University scientists have developed a new technique to explore the deep history of Australia’s landscapes. The approach could help researchers understand how the environment responds to geological activity and climate shifts, while also offering clues about where valuable mineral deposits may be located. The international research team was led…

400 million-year-old fish fossils reveal how life began moving onto land

Scientists are uncovering new details about some of the earliest fish to inhabit Earth more than 400 million years ago. Fresh analyses from two separate studies are helping researchers better understand ancient lungfish, a group that represents the closest living relatives of land vertebrates. The discoveries come from work led…

Astronomers think they just witnessed two planets colliding

Anastasios (Andy) Tzanidakis was reviewing archived telescope observations from 2020 when he noticed something unusual. A seemingly ordinary star called Gaia20ehk was behaving in a way astronomers rarely see. Located about 11,000 light years from Earth near the constellation Pupis, Gaia20ehk is a stable “main sequence” star similar to our…

Strange chirping supernova confirms long-debated magnetar theory

For many years, astronomers have relied on distant supernovae as cosmic beacons to study the universe and test the laws of physics. But while analyzing one particular stellar explosion, Joseph Farah, a fifth year graduate student at UC Santa Barbara, noticed something entirely unexpected. The supernova appeared to produce a…

A “ghost” great white shark just reignited a Mediterranean mystery

On April 20, 2023, local fishermen accidentally caught a juvenile great white shark (Carcharodon carcharias) off the coast of the eastern peninsula. The young shark measured about 210 cm in length and weighed roughly 80-90 kg. Encounters like this are extremely uncommon in the region, prompting scientists to take a…

Scientists discover seven strange frog-like insects hidden in uganda’s rainforest

A scientist from Anglia Ruskin University (ARU) in Cambridge, England has identified seven previously unknown species of a distinctive frog-like insect. The insects belong to the genus Batracomorphus, a group of leafhoppers. Dr. Alvin Helden discovered the new species while conducting fieldwork in the tropical rainforest of Uganda. The name…

Teens sleep longer and perform better when school starts later

Many high school students find it hard to fall asleep early, which makes waking up for early morning classes a challenge. The reason lies in biology. During adolescence, the body’s internal clock naturally shifts later, meaning teenagers tend to feel alert later at night than adults do. Because of this…

Scientists solve the mystery of a vitamin B5 molecule that powers your cells

The human body produces a molecule from vitamin B5 that plays a central role in metabolism, the network of chemical reactions that keeps cells alive and functioning. If the body cannot produce this molecule properly, the consequences can be widespread. Problems with its production can disrupt many organ systems and…

Scientists turn brain cells into Alzheimer’s plaque cleaners

The newest class of Alzheimer’s disease medications is the first to show that it can slow the disease itself. These treatments typically allow patients to remain independent for about 10 additional months. Known as monoclonal antibodies, the drugs work by lowering levels of amyloid, a harmful protein that accumulates in…
