Phys.org / Molecular nanostructures can be activated using ultrasound
Researchers from Heinrich Heine University Düsseldorf (HHU) have taken an important step toward developing intelligent molecular materials. The team headed by Dr. Bernd M. Schmidt (Institute of Organic Chemistry and Macromolecular ...
Phys.org / Euclid discovers the most ancient quasars in the universe
The European Space Agency's Euclid space telescope has discovered 31 of the most ancient quasars ever found. Two of these giant and dazzling galaxy cores, powered by gargantuan black holes, are the earliest quasars yet observed ...
Phys.org / China's space probe reaches asteroid after 1-billion-kilometer chase for first sample return
China's Tianwen-2 space probe, which is set to bring back samples from an asteroid for research, has reached its target after traveling 1 billion kilometers (620 million miles) over more than a year, the Chinese space agency ...
Phys.org / Alpine butterflies track warming uphill, but habitat loss may pose bigger risk
A new study published in the journal Alpine Entomology has found that alpine butterflies in the Swiss National Park are closely matching the pace of local warming in their range shift to higher elevations.
Phys.org / Scientists discover smart way to supercharge soft robotics and better support rehabilitation patients
Researchers have found an ingenious way to make soft robots and wearable technology more than three times more powerful by harnessing the surface tension of a tiny liquid metal droplet smaller than a raindrop.
Phys.org / The evolutionary pressure behind sexual asymmetry revealed in yeast cell study
A major transition in evolution is the shift from asexual to sexual reproduction in early organisms. But why would a yeast cell, which usually reproduces asexually, choose to mate with a very different partner in times of ...
Phys.org / New workflow tool gives scientists a clearer view of how DNA is regulated
Researchers from the Cancer Science Institute of Singapore (CSI Singapore) at NUS have developed a new method that allows scientists to better understand how DNA is organized and regulated inside cells. The study, published ...
Phys.org / Researchers use AI to evaluate a systematic framework to describe molecular order in liquid water
Water is the most abundant liquid on Earth's surface, and it is highly anomalous compared with other liquids because it expands upon freezing. The anomalies in water have been linked to how its microscopic structure changes ...
Phys.org / Neutral lipids enable precision control over supramolecular polymerization
The formation of supramolecular polymers within living cells is an emerging strategy for regulating cellular functions, and lipid droplets (LDs) are promising environments for such processes. LDs are cellular organelles composed ...
Phys.org / Scattered bronze bells in Chinese lord's 2,600-year-old tomb point to ritual deactivation
When archaeologists opened the 2,600-year-old tomb of an ancient Chinese lord, they discovered his magnificent bronze bells had been scattered, their wooden hangings broken. But the most mysterious part of all: This was apparently ...
Phys.org / Rare 309-million-year-old fossils suggest early tetrapods developed without tadpole phase
Scientists have long posited that the earliest water animals to transition to land had amphibious tadpole features, going through a metamorphosis akin to that of today's frogs.
Phys.org / Rats show empathy, according to model
A rat first frees a cagemate rat and then shares food with it. Is this animal just as empathetic as humans? In an American study from 2011, researchers observed that rats first freed their fellow rats from a cage and then ...
