Phys.org / The herring fishery that took 400 years to rebound—and what it teaches us today
From the 13th to the 16th century, herring from the Sound—the strait in the Baltic Sea between Denmark and Sweden—was one of northern Europe's most important trade goods. Salted herring from the so-called Skanör-Falsterbo ...
Phys.org / New metal-free molecules glow deep red in water and boost MRI contrast in test images
Bioimaging technologies, such as fluorescence imaging (FI) and magnetic resonance imaging (MRI), are powerful tools in basic research and clinical medicine. But they have drawbacks. FI allows researchers to visualize cells ...
Phys.org / Meteor hit Oklahoma 100 million years later than previously thought
Researchers at The University of Texas at Austin have rewritten a small part of Oklahoma's geologic history with global implications for ancient life. Below the surface of the small town of Ames, Oklahoma, a meteor impact ...
Phys.org / Ancient spearheads reveal how Ice Age humans learned the land
At the end of the last ice age, early humans crisscrossed the Americas following seasons, rivers and game, often with a trusty spear in hand. Nearly 13,000 years later, archaeologists are using those spearheads to study how ...
Phys.org / Dopamine-based nanotubes combine heat, electrical stimulation and antioxidant release for first time
The research group at the Istituto Italiano di Tecnologia in Pontedera (Pisa), led by Gianni Ciofani, has developed new organic nanoparticles that combine multiple therapeutic functions in a single material for the first ...
Phys.org / Scientists find lunar 'magnetic fossil' in Chang'e-6 samples
The moon no longer has a global magnetic field, but lunar rocks and soils still contain records of ancient magnetism. Studying the magnetic minerals in these samples can help scientists understand how the moon's magnetic ...
Phys.org / Waves find order in the chaos of an oddly shaped cavity
When light or sound bounces around inside an oddly shaped room, its reflections can quickly become difficult to predict. But new research led by scientists at the Advanced Science Research Center at the CUNY Graduate Center ...
Phys.org / Laser temporarily reprograms ultrathin optical device without electrodes
A tiny device that can be reprogrammed using a laser could lead to adaptable devices for computing, imaging and telecommunications. Most devices are built to perform a particular job. If you want them to do something different, ...
Phys.org / Testing tiny telescope robots reveals design changes that could improve galaxy maps
Astronomers have cataloged billions of stars and hundreds of billions of galaxies. We have found thousands of planets orbiting stars. We can also map where galaxies sit and trace how the universe changes over time.
Phys.org / New formulation helps RNA vaccines withstand high temperatures
RNA vaccines, which have proved effective against COVID-19, are now being developed for many other diseases, including cancer. One drawback is that they require ultracold storage, but MIT researchers have found a promising ...
Phys.org / How to balance quantum batteries' high power with stable energy delivery
Quantum batteries are an emerging area of research, with progress coming from theoretical studies and proof-of-principle experiments in small quantum systems. Unlike conventional chemical batteries used in everyday life, ...
Phys.org / Worm experiments reveal how epigenetic effects persist across generations
Every cell in an organism contains the same DNA, which carries all the instructions needed for it to function. Yet cells do not all use the same genes: A nerve cell, for example, does not activate the same genes as a muscle ...
