Blinding diseases caused by the degeneration of photoreceptors, such as age-related macular degeneration (AMD) and retinitis pigmentosa (RP), affect 200 million people worldwide and represent the leading causes of visual impairment and blindness. Beyond the personal impact on qua

In autoimmune disorders, immune cells targeting "self" proteins are mistakenly activated, resulting in abnormal expansion and responsiveness. These disorders are known to reduce patients' quality of life over a prolonged period. This can be attributed to CD4+ T cells, which play

US health authorities on Friday activated the highest level of response to the Ebola outbreak in the Democratic Republic of Congo, while announcing the shipment of experimental treatments to the region.

We have identified the gene that, when activated, initiates the developmental programme that results in cells forming a human body

In an international experiment, researchers observed Jahn–Teller polarons—quasiparticles that could play an important role in future ultrafast spintronic devices. These polarons emerged within the crystal lattice of cobalt oxide that had been activated by carefully tailored laser

A tiny, aquatic, single-celled organism can contract to one-quarter of its body length in less than 5 milliseconds—hundreds of times faster than a human can blink. Researchers have discovered that the organism, Spirostomum ambiguum, uses a calcium-activated protein network in a f

Antibiotic resistance is becoming an accelerating crisis because of the overuse and misuse of antibiotics over many years. The problem is exacerbated when antibiotics wipe out susceptible bacteria but leave resistant bacteria behind to multiply, further spreading resistance. Ther

Carbon materials, such as carbon fibers and activated carbons, are essential across a wide variety of fields, encompassing everything from aerospace engineering to fuel cells and thermal insulation. For decades, Raman, infrared and X-ray photoelectron spectroscopy (XPS) have been
