Phys.org / Chemists snap together complex 3D molecules from highly reactive 'radicals'—without losing their shape
Building the complex 3D molecules needed for new medicines has always been a bit like assembling a puzzle with pieces that keep trying to flip over. Now, chemists at Scripps Research have found a way to snap two such molecular ...
Phys.org / Why cells started sticking together could help explain how animals first evolved
A recent study by Ruibao Li and Jennah Dharamshi published in Nature may help us understand the beginnings of animal evolution billions of years ago. These findings are the result of a collaboration among researchers at Indiana ...
Phys.org / A new kind of entanglement helps quantum sensors tune out noise
In a quest to build the most accurate quantum sensors in the world, scientists are constantly improving their performance, making them more precise, more stable and more reliable. But eventually, physical constraints will ...
Phys.org / Why animal calls sound alike in time: Most species share a common communication tempo
From insects to great apes, by way of birds and fish, animals communicate through an extraordinary variety of sounds. While the pitch or timbre of their vocalizations matters, rhythm may play a more fundamental role. Scientists ...
Phys.org / Ocean glow meets 3D printing with living gels that sense mechanical force
The integration of biological organisms into synthetic structures offers a radical new pathway for developing intelligent, self-powered materials. Researchers have pioneered an innovative approach to biomanufacturing by using ...
Phys.org / AI fast-forwards molecular simulations by 10,000-fold
A new AI model has become so good at predicting how molecules evolve over time that, in the future, it could speed up the costly and time-consuming process of testing new drugs. In the long term, this technology could facilitate ...
Phys.org / Massive Kamchatka earthquake has extended rupture that overlaps 1952 event, researchers find
Researchers combining two methods to reconstruct the rupture evolution of the July 2025 magnitude 8.8 Kamchatka earthquake found the rupture from the megathrust event extended about 500 kilometers (311 miles) from its epicenter.
Phys.org / Light echoes reveal possible dark matter buildup around supermassive black holes
We may not know what dark matter is, but we keep getting whiffs of it. "We are reaching a point where the observational evidence for dark matter is simply undeniable," said Mayank Sharma, a Virginia Tech graduate student ...
Phys.org / Why shame is an evolution-based defense mechanism
It is unpleasant, strange and often comes as a surprise: shame. But why do we feel it? An international study has shed new light on the emotion of shame, which has long been considered harmful. The conclusion: Shame is not ...
Phys.org / Parents' heat warning songs may prime zebra finch chicks for heat before they hatch
Sealed within an eggshell, how can chicks prepare for the world into which they are about to hatch, with no obvious direct communication channel across the shell? Adult zebra finches produce distinctive high-pitched warning ...
Dialog / Binary asteroids' puzzling configurations may link to multi-satellite history
Binary asteroid systems are widespread throughout our inner solar system. For decades, the standard paradigm held that many of them form when a rapidly spinning primary asteroid casts off material, which then reaccumulates ...
Phys.org / Newly synthesized fullerene material remains metallic even under low temperatures
An international team whose research was coordinated by Osaka Metropolitan University (OMU) has reported the survival of metallic behavior in the strongly correlated molecular material ytterbium cesium fulleride (Yb₂CsC₆₀). ...
