The universe is expected to corrupt in 10 years, much earlier than previously thought
The artistic impression of neutron stars slowly “evaporate” through Hawking-like radiation. Credit: Daniëlle Futselaar/Artsource.nl The universe is falling apart much faster than thought. This is illustrated by calculations by three Dutch scientists regarding the so-called Hawking radiation. They calculate that it will take about 1078 years for the last star to die. This is much shorter than the previously assumed…

Protoplanetary discs are much smaller than previously thought, according to new research
Images of 73 protranetary discs in the Lupus Star Forming area (two images contain binary stars). When compared to our own solar system, only a portion of the disk extends beyond Neptune’s orbit. Most of the observed disks are small and have no gaps or ring-like structures. Credit: Guerra-Alvarado et al. Many protranetary discs on which new planets are formed…

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…

Webb reveals that planet-forming disks can last longer than previously thought
This diagram shows the underlying stars surrounded by discs forming a planet of gas and dust. The planetary formation process displays gaps on disks not shown in this diagram. A stream near the center indicates that the problem from the disk is still falling to the star. Credit: NASA/CXC/m. Weiss If there was something like a cosmic photo album, it…

Unexpected discovery of collagen structures indicates greater diversity than previously believed
Characterization of A, B-CRT and C peptide assemblies: Credit: ACS Central Science (2025). doi:10.1021/accentsci.5c00018 Collagen, the body’s most abundant protein, has long been considered a predictable structural component of tissue. However, a new study led by Jeffrey Hartgarin and Tracy Yu of Rice University, in collaboration with Mark Kreuzberger and Edward Egelman of the University of Virginia (UVA) is likely…

The Arctic groundwater supplies more carbon to the sea than previously known.
An aerial image of the research site in Kakutobik Lagoon in North Alaska. Credit: Nathansongdaman A new study at Austin School at Texas University allows relatively small amount of groundwater to release a large amount of carbon through the Alaska tundra and contribute to climate change. Researchers consist of only a small part of the water that is excreted in…

New “all-optical” nanoscale force sensor accesses previously inaccessible environments
Illustration of atomic arrangement within a single lanthanide-doped nanocrystal. Each lanthanide ion can emit light. Credit: Andrew Mueller/Columbia Engineering Mechanical forces are an essential feature of many physical and biological processes. Telemetry of mechanical signals with high sensitivity and spatial resolution is required for a wide range of applications, from robotics to cell biophysics and medicine, and even space travel.…

The moon may be older than scientists previously thought. New research sheds light on its history
Credit: Pixabay/CC0 Public Domain Physicists, chemists, and mathematicians walked into the bar. It sounds like the beginning of a bad joke, but in my case it was the beginning of an idea that could change the way scientists think about the history of the moon. All three of us were interested in the moon, but from different perspectives. As a…

Oceans emit sulfur, cooling the climate more than previously thought
Scientists have successfully quantified methanethiol emissions in the oceans on a global scale for the first time. Credit: Rafel Simó (ICM-CSIC) Researchers have for the first time quantified global emissions of sulfur gas produced by marine life, revealing that sulfur gas is cooling the climate more than previously thought, especially in the Southern Ocean. The study, published in the journal…

How we discovered that the ocean surface absorbs far more carbon dioxide than previously thought
Credit: Pixabay/CC0 Public Domain The ocean plays a vital role in capturing carbon dioxide (CO₂) from the atmosphere and has so far acted as a brake on the full effects of climate change. Current estimates of CO₂ from the atmosphere lost to the ocean, commonly referred to as ocean CO₂ sinks, suggest that approximately 25% of all human CO₂ emissions…
