Why AI has trouble predicting the fury of hurricane intensity‎

Artificial intelligence has revolutionized weather forecasting in just a few years, with global AI weather models now able to produce forecasts that rival some of the world's best physics-based prediction systems.

NEET with a disability: What's holding back visually impaired young people who want to work‎

I have been fortunate in my research to follow 80 young people with vision impairment over 11 years. I tracked their journeys from school into adulthood, speaking with them at regular intervals to learn what had happened since we last spoke, what had gone well and what could have been improved.

Looking for #womenshealth information on Instagram? 4 out of 10 posts are ads‎

A woman in her 40s scrolls through Instagram. Between photos of friends, recipes and vacation photos, she comes across a video about perimenopause. The woman on screen explains that perimenopause is to blame for feeling tired, having trouble remembering things, struggling to sleep or gaining weight.

Black hole jets reach far beyond galaxies' visible edges, potentially deciding their fate‎

Galaxies are enormous and hold hundreds of billions of stars. These stars form from cold, dense gas. Every large galaxy, including the Milky Way, is wrapped in a huge envelope of gas called the circumgalactic medium, or CGM. This reservoir of raw material stretches 10–20 times the size of the visible portion of the galaxy.

Why earwigs infected by parasitic worms head towards water‎

Earwigs, small, elongated insects with distinctive pincers at the rear of their abdomens, have little reason to enter open water. While many earwig species are attracted to damp environments, they typically avoid open water. Yet past studies have found that European earwigs infected with a parasitic roundworm called Mermis nigrescens tend to head toward open water. The molecular and biological reasons for this unusual behavior have not been fully uncovered.

Pumpkin-derived enzyme weakens peanut proteins' binding to allergy antibodies in lab tests‎

Peanut allergy is one of the most serious food allergies and can lead to sudden, life-threatening reactions. Researchers from Wroclaw University of Environmental and Life Sciences, in collaboration with Wroclaw Medical University, investigated whether a natural enzyme obtained from figleaf gourd (Cucurbita ficifolia) could reduce recognition of peanut proteins by antibodies involved in allergic reactions.

Engineers teach spacecraft to 'dream' their way to the space station‎

Docking with the ISS may seem simple. However, actually doing so shows how difficult orbital mechanics can be. It's like traveling down a highway at 28,000 km/hr (17,000 mph) and parallel parking in an open garage on a multibillion-dollar laboratory traveling at the same speed. If you try to accelerate forward, you actually drift up, and there's no air friction to naturally slow you down. Oh, and if you hit the lab, everyone aboard both your craft and the station dies, and the resulting debris field could wipe out dozens of satellites and even harm people on the ground. No pressure, obviously.
