Comet 3I/ATLAS displays greenish hue in new Gemini North telescope images‎

Gemini North captured new images of Comet 3I/ATLAS after it reemerged from behind the sun on its path out of the solar system. The data were collected during a Shadow the Scientists session—a unique outreach initiative that invites students around the world to join researchers as they observe the universe on the world's most advanced telescopes.

German adults outperform international peers in complex problem-solving tasks, study finds‎

Adults in Germany are better than the international average at coping with problems in new and complex situations. However, this adaptive problem-solving skill depends more heavily on sociodemographic characteristics than in other countries. This is shown by a new evaluation of the latest PIAAC study, in which adults in around 30 countries were tested.

Unique bond identified as key to viral infection speed‎

Viruses are typically described as tiny, perfectly geometric shells that pack genetic material with mathematical precision, but new research led by scientists at Penn State reveals a deliberate imbalance in their shape that helps them infect their hosts.

DNA origami lattices on silicon open new possibilities for large-scale nanofabrication‎

A dissertation study at the University of Jyväskylä (Finland) developed two-dimensional fishnet-like structures from DNA origami for silicon surfaces and investigated how different conditions affect their formation. The results provide new possibilities for DNA-assisted lithography and thus for the fabrication of new types of materials, for example, for optics.

A new medium for canine stem cells that doesn't contain any human components‎

Canine induced pluripotent stem (iPS) cells possess the ability to differentiate into any type of cell, making them a useful tool for investigating common canine diseases and disease states, including those of humans.

Researchers track down elusive rain-triggering 'shear lines' in the Philippines‎

Much of the heavy rains that hit the Philippines during the Amihan northeast monsoon season between November and March are triggered by "shear lines": kilometers-long bands of converging warm and cold air that are constantly shifting and difficult to spot even via satellite.

Smarter tools for peering into the microscopic world developed‎

The microscopic organisms that fill our bodies, soils, oceans and atmosphere play essential roles in human health and the planet's ecosystems. Yet even with modern DNA sequencing, figuring out what these microbes are and how they are related to one another remains extremely difficult.

Feedback loops from oil fields accelerate Arctic warming and other atmospheric changes, study shows‎

The climate is changing and nowhere is it changing faster than at Earth's poles. Researchers at Penn State have painted a comprehensive picture of the chemical processes taking place in the Arctic and found that there are multiple, separate interactions impacting the atmosphere.

Rare-earth europium substitution allows for more control over CO₂-to-fuel conversion‎

The electrochemical CO2 (carbon dioxide) reduction reaction takes harmful pollutants and transforms them into valuable products like fuel. However, selectively tailoring various processes in this reaction to successfully and efficiently arrive at a particular desired outcome remains a challenge.

Earthquake rupture along Main Marmara Fault shows eastward progression towards Istanbul‎

In April 2025, the Main Marmara Fault below the Sea of Marmara in northwestern Türkiye experienced its largest earthquake in over 60 years. In a study published in Science, a team of researchers led by Prof. Dr. Patricia Martínez-Garzón from the GFZ Helmholtz Center for Geosciences in Potsdam, Germany, analyzes nearly two decades of seismic data framing the 2025 April magnitude M 6.2 earthquake.
