Detecting them allows astronomers to probe the early universe and understand how the first heavy elements formed and how the earliest stellar populations lived and died. Missions like HiZ-GUNDAM, a satellite planned for launch in the 2030s by the Japan Aerospace Exploration Agency (JAXA), aim to detect these distant explosions in real time.<\/p><\/div><\/li>

Aprila 2026. at 19:00 <\/small>Ovarian cancer remains the deadliest gynecologic cancer, largely because it is rarely found early. Symptoms are often vague, and existing screening approaches\u2014such as blood tests and transvaginal ultrasound\u2014can miss the disease at stages when treatment is most effective. In recent years, research has reshaped understanding of how many aggressive ovarian cancers begin, pointing not to the ovary itself, but to the fallopian tubes.

One comes from polarization, which describes how the electric field rotates. The other comes from the shape of the wavefront itself, which can twist like a corkscrew as it travels. This second form, known as orbital angular momentum, has attracted wide interest because it allows light to encode information, interact with matter in new ways, and probe physical and biological systems. Despite this promise, producing well-defined twisted light in free space remains technically challenging, especially when the light originates from small or localized sources.<\/p><\/div><\/li>

<\/a><\/div>Optical analysis of human milk advances breastfeeding research<\/a><\/span>on 12. Marta 2026. at 20:50 <\/small>The World Health Organization (WHO) recommends that babies be exclusively breastfed for the first six months of life, since breastfeeding plays an important role in public health. Nevertheless, many mothers struggle with initiating and maintaining breastfeeding. Although this can be ascribed to a variety of limiting factors, many mothers (40% to 60%) stop breastfeeding due to a perception of low milk supply. Evidence is increasing that low milk supply is certainly not a perception only, with an estimated incidence of actual lactation insufficiency of 10% to 15%. The underlying causes of actual lactation insufficiency are currently poorly understood.<\/p><\/div><\/li>

These devices use radiation pressure\u2014the force exerted when light reflects from a surface\u2014to generate thrust.

Februara 2026. at 19:00 <\/small>Cochlear implant surgery helps people with severe hearing loss by placing an electronic device inside the inner ear. To reach the inner ear, surgeons must first remove part of a bone behind the ear, in a procedure called mastoidectomy. The shape of this surgically created cavity varies from patient to patient and has no clear outer boundary, making it difficult to anticipate using traditional image-analysis tools. Better prediction of this shape before surgery could support navigation systems, robotic tools, and improved visualization for surgeons, along with better outcomes for patients.<\/p><\/div><\/li>
