Phys.org / Team develops modulator for compact photonic integrated circuits
Researchers at Skoltech have developed an ultra-compact electro-optic modulator based on silicon photonics and plasmonics that enables high-efficiency optical signal control within a small device footprint. The development ...
Science X / Crows look plain black to us, but their feathers contain a secret visual code that changes with age
To understand birds—their social relationships, their choices, even their feathers—you need to understand the way they see the world. That can be a challenging task, because birds and humans literally see their environments ...
Phys.org / Understanding how oxygen is delivered to tissues at the microscopic level
Researchers at Kyushu University and Institute of Science Tokyo have developed a new computational model that can simulate the transport of oxygen by red blood cells (RBCs) through tiny blood vessels—or capillaries—and their ...
Phys.org / Light-based scans reveal how cells can be stable yet adaptable
Our cells adjust to ever-changing conditions while preserving internal states necessary for survival, but exactly how they achieve both adaptability and stability remains unclear. For the first time, researchers have used ...
Phys.org / Botany's answer to Darwin's finches shows evolution in real time
A new study reveals how a remarkable group of plants on the Galápagos Islands developed their diverse leaf shapes—offering unique insight into evolution at the genetic level. A large international team of researchers has ...
Medical Xpress / Mechanical forces from the beating heart may help prevent cancer cell growth
Scientists may have discovered another way the human body tries to protect itself from cancer. New research on mice suggests that the heart's constant beating may prevent tumor growth in cardiac tissue. Most organs are vulnerable ...
Phys.org / More activity means less response in active materials
For some time, researchers have assumed that solid materials could gain more useful properties by making their microscopic components more active. Now, a team led by Jack Binysh at the University of Amsterdam has found that ...
Phys.org / New approach to detect ultra-rare part-per-sextillion isotopes could also sharpen dark matter searches
The detection and study of isotopes, atoms of the same element that have different numbers of neutrons, could expand the scope of physics research and enable new scientific discoveries. So far, rare isotopes have been primarily ...
Phys.org / 'Aquila Booster' challenges theoretical limits of particle acceleration in pulsar wind nebulae
The Large High Altitude Air Shower Observatory (LHAASO) has detected PeV (1015 eV) gamma-ray emission from a pulsar wind nebula powered by PSR J1849-0001 in the constellation Aquila, marking the discovery of a new PeVatron ...
Phys.org / How deceptive content reached millions of voters during the 2020 US elections
Over the past decades, the diffusion of fake news and other deceptive content on social media platforms has become a heated topic of debate. Some past studies have explored the broad impact of online misinformation, while ...
Phys.org / Why groups slowly stop working well together, even when conditions are good
Humans are generally a cooperative bunch and most of us probably like to think of ourselves as reliable team players. Cooperation is useful for all sorts of reasons, from running a business and managing community resources ...
Phys.org / DNA molecular computer combines memory and computing at scales below 2 nm
Until now, molecular-level DNA circuits have mainly been used for simple tasks, such as detecting the presence of cancer-related substances. However, these systems have faced a key limitation: once a reaction occurs, the ...
