Phys.org / How do clouds form in Antarctica? The first flight-based aerosol measurements in 20 years
Antarctica plays a crucial role in Earth's climate system by reflecting solar radiation back into space. The large white ice surfaces and clouds play a decisive role in this process. However, how clouds actually form in Antarctica, ...
Medical Xpress / Blood tests can reveal risk of ulcerative colitis—long before becoming ill
Researchers at Örebro University have identified blood markers that can indicate who is at risk of developing ulcerative colitis—a chronic inflammatory bowel disease—later in life. These markers can be present for many ...
Medical Xpress / Remote-controlled CAR-T cells use venetoclax to disengage from tumors
Among the most promising tools of cancer therapy, engineered immune cells known as chimeric antigen-receptor (CAR) T cells have already transformed the treatment of blood cancers. Yet, despite their promise, CAR-T cells do ...
Phys.org / Stronger scents and healthier crops: Unlocking plants' hidden potential through precision gene editing
Scientists have long sought to understand why some plants are fragrant powerhouses while others remain subtle. Now, a research team from the Hebrew University of Jerusalem has cracked a genetic "bottleneck," using precision ...
Phys.org / Q&A: How the 'science of reading' is reshaping literacy education
Stanford Professor Rebecca Silverman discusses a transformative movement backed by research that is changing literacy instruction in schools nationwide. After decades of debate over the most effective way to teach literacy, ...
Phys.org / Endangered marine life is being caught in fishing nets, but it doesn't need to be
Hundreds of thousands of marine animals are killed every year after becoming accidentally caught in commercial fishing nets. Sharks, skates and rays are at particular risk, alongside turtles, seals, whales and dolphins, many ...
Tech Xplore / Atom-thin ferroelectric transistor can store 3,024 polarization states
Over the past few decades, electronics engineers have been trying to develop new neuromorphic hardware, systems that mirror the organization of neurons in the human brain. These systems could run artificial intelligence (AI) ...
Phys.org / Transistor-like MXene membranes enhance ion separation
By applying voltage to electrically control a new "transistor" membrane, researchers at Lawrence Livermore National Laboratory (LLNL) achieved real-time tuning of ion separations—a capability previously thought impossible. ...
Phys.org / A new method to decode how DNA 'switches' control gene activity
DNA is the blueprint of life. Genes encode proteins and serve as the body's basic components. However, building a functioning organism also requires precise instructions about when, where, and how much those components should ...
Medical Xpress / The skinny on fat: 'How to eat to avoid chronic diseases'
This is the first celebration of Heart Month (it comes every February) since the release of the updated dietary guidelines for Americans. The new recommendations are meant to represent the most current scientific evidence ...
Phys.org / Expands the genetic alphabet: Artificial DNA base pair uses halogen bonds to form stable structures
For the first time, researchers have succeeded in developing an artificial DNA base pair that is based on a different chemical force than natural genetic material. While the common natural DNA building blocks are held together ...
Tech Xplore / LLMs violate boundaries during mental health dialogues, study finds
Artificial intelligence (AI) agents, particularly those based on large language models (LLMs) like the conversational platform ChatGPT, are now widely used daily by numerous people worldwide. LLMs can generate texts that ...
