Phys.org / Molecular system can distinguish and neutralize cancer cells, paving the way for 'smart' drugs
How can cancer cells be targeted without damaging healthy tissue? This is one of the major challenges facing oncology today. Using synthetic DNA strands, a team from the University of Geneva (UNIGE) has created a "smart" ...
Phys.org / Cosmic collision of galaxies mapped by Maunakea telescope
An astronomer at the University of Hawaiʻi at Hilo is using data from the Canada–France–Hawaiʻi Telescope (CFHT) on Maunakea to help reconstruct a slow-motion cosmic collision, one that has been unfolding for hundreds of ...
Medical Xpress / Premature and small births are linked to lifelong learning problems
Being born early or at a lower weight is linked to lower IQ scores and poorer educational outcomes in school and beyond, according to a new study published in the journal JAMA Pediatrics. Researchers from the UK and the Netherlands ...
Phys.org / New model shows how behavioral flexibility affects animal evolution
When the environment changes dramatically, animals from mollusks to crows can make big changes in their behavior that enable them to survive. For example, marmots and ground squirrels in California are spending more time ...
Phys.org / Hidden features in X-rays could radically change how we measure and understand them
Hidden features uncovered in X-ray signals are set to overturn a key scientific theory and fundamentally change how X-rays are interpreted across fields of physics, chemistry, biology and materials science, new research reveals. ...
Phys.org / Wisconsin-sized chunk of Alaskan permafrost is thawing: Geoscientists say climate may never be the same
In a first-of-its-kind study, a team of researchers led by geoscientist Michael Rawlins at the University of Massachusetts Amherst has shown in fine-grained detail what happens when Arctic permafrost thaws. Focusing on a ...
Phys.org / Helical liquid crystals can flip light's chirality under ultralow electric fields
The direction in which the electromagnetic field of circularly polarized light rotates can be easily reversed by applying a voltage, RIKEN researchers have demonstrated. This could enable a new generation of optical devices ...
Phys.org / AI's fluency in other languages hides a Western worldview that can mislead users
A friend in Indonesia recently told me about a conversation he had with ChatGPT. He had typed a question in Indonesian—Bahasa Indonesia—about how to handle a difficult family dispute. The chatbot responded fluently, in perfect ...
Phys.org / Useful quantum computers could be built with as few as 10,000 qubits, team finds
Quantum computers of the future may be closer to reality thanks to new research from Caltech and Oratomic, a Caltech-linked start-up company. Theorists and experimentalists teamed up to develop a new approach for reducing ...
Phys.org / Building desktop particle accelerators to unlock new realms of research
Using high-intensity lasers, researchers have taken an important step toward miniaturization of particle accelerators by demonstrating free-electron laser amplification at extreme ultraviolet wavelengths (27–50 nm), with ...
Tech Xplore / Molecular additive boosts silicon-perovskite tandem solar cell efficiency to 32.76%
Solar cells, devices that can convert sunlight into electricity, are among the most promising solutions to source energy without contributing to air pollution. While most commercially available solar cells are based on silicon, ...
Phys.org / Silicon quantum computer performs logical operations for the first time
Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, silicon's compatibility with existing chip technology and its long coherence times in silicon-based ...
