Phys.org / AI bosses are creating a new problem for gig workers
For millions of gig workers driving for companies such as Uber Eats, DoorDash and Deliveroo, there is no human manager to call, no supervisor to appeal to and no office to walk into. Decisions about pay, performance, penalties ...
Phys.org / Strength-in-numbers X-ray technique can map previously unattainable atomic structures
For many decades, the method to obtain atomic-level descriptions of chemical compounds and materials—be it a drug, a catalyst, or a commodity chemical—has been X-ray crystallography. This method has a known weakness: ...
Phys.org / Direct imaging captures the crystalline vibrations of a supersolid made of atoms and light
The 20th century was marked by the discovery of exotic states of matter. First, liquid helium was observed to flow without friction at extremely low temperatures, a phase now known as superfluid. Soon after, it was also discovered ...
Phys.org / New ABF crystal delivers high-performance vacuum ultraviolet nonlinear optical conversion
Vacuum ultraviolet (VUV, 100–200 nm) light sources are indispensable for advanced spectroscopy, quantum research, and semiconductor lithography. Although second harmonic generation (SHG) using nonlinear optical (NLO) crystals ...
Medical Xpress / Interferon signal reprograms macrophage mitochondria to promote inflammation resolution, finds study
When our body fights an infection, the immune system must quickly activate defenses and trigger a beneficial inflammatory response. But it is just as important to resolve that inflammation and return to homeostasis. Macrophages ...
Phys.org / Extracellular vesicles manage to slip gene edits into Pneumocystis fungi
Pneumocystis is an unwieldy genus of fungal pathogens that cause severe pneumonia, particularly in immunocompromised people like those with HIV/AIDs or who have received organ transplants. However, the mechanisms by which ...
Phys.org / Massive star WOH G64 is still a red supergiant—for now
An international team of astronomers led by a researcher at Keele University has solved a long-standing cosmic mystery surrounding one of the most extreme stars ever observed. The star, known as WOH G64, is located in the ...
Phys.org / Study offers practical guide for AI application in marine conservation and fisheries
Every day, thousands of images and signals are collected at sea. Sonar, buoys, satellites, and cameras installed on ships generate enormous amounts of data. Artificial intelligence (AI) is already being used to interpret ...
Phys.org / Toothbrush-activated powder whitens, repairs and protects teeth
Even with regular brushing, teeth can become stained from genetic factors or consuming foods and drinks like tomatoes and coffee. Chemical whiteners can help, but they can also damage teeth in the process. So, researchers ...
Tech Xplore / Human-led AI opens tech jobs for refugees
AI can help displaced people avoid exploitation, but humans must call the shots, warn experts. For Susan Achiech, life began in Kenya's Kakuma refugee camp, where her South Sudanese parents fled to for safety in the early ...
Phys.org / Land use acts as a 'silent amplifier' of extreme heat, AI-driven study reveals
A new study using Explainable Artificial Intelligence (XAI) has revealed land-use change—particularly deforestation and unplanned agricultural expansion—is dramatically intensifying heat waves across Africa, with findings ...
Phys.org / Cell surface glycoRNA clusters found to fine-tune growth factor signaling
The recent discovery of glycoRNAs on the cell surface upended the world of cell biology. These glycoRNAs were found to form highly organized clusters with cell surface RNA binding proteins (csRBPs), but their purpose remained ...
