Signs of Multiple Sclerosis show up in Blood Years Before Symptoms, study finds

In a discovery that could hasten treatment for patients with multiple sclerosis (MS), UC San Francisco scientists have discovered a harbinger in the blood of some people who later went on to develop the disease.

In about 1 in 10 cases of MS, the body begins producing a distinctive set of antibodies against its own proteins years before symptoms emerge. These autoantibodies appear to bind to both human cells and common pathogens, possibly explaining the immune attacks on the brain and spinal cord that are the hallmark of MS.

The findings were published in Nature Medicine on April 19.

MS can lead to a devastating loss of motor control, although new treatments can slow the progress of the disease and, for example, preserve a patient’s ability to walk...

An international collaboration of researchers, led by Philip Walther at University of Vienna, have achieved a significant breakthrough in quantum technology, with the successful demonstration of quantum interference among several single photons using a novel resource-efficient platform. The work published in the journal Science Advances represents a notable advancement in optical quantum computing that paves the way for more scalable quantum technologies.

Interference among photons, a fundamental phenomenon in quantum optics, serves as a cornerstone of optical quantum computing.

It involves harnessing the properties of light, such as its wave-particle duality, to induce interference...

Last year alone, more than 600,000 people in the United States died from cancer, according to the American Cancer Society. The relentless pursuit of understanding this complex disease has shaped medical progress in developing treatment procedures that are less invasive while still highly effective.

Immunotherapy is on the rise as a possible solution...

Microsoft’s AI app VASA-1 makes Photographs Talk and Sing with believable Facial Expressions

Microsoft's AI app VASA-1 makes photographs talk and sing with believable facial expressions
Given a single portrait image, a speech audio clip, and optionally a set of other control signals, our approach produces a high-quality lifelike talking face video of 512× 512 resolution at up to 40 FPS. The method is generic and robust, and the generated talking faces can faithfully mimic human facial expressions and head movements, reaching a high level of realism and liveliness. (All the photorealistic portrait images in this paper are virtual, non-existing identities.). Credit: arXiv (2024). DOI: 10.48550/arxiv.2404.10667

A team of AI researchers at Microsoft Research Asia has developed an AI application that converts a still image of a person and an audio track into an animation that accurately portrays the individual speaking or singing the audio track with appropriate facial ...
