The Kronshtadskiy subglacial lake near East Antarctica's Amery Ice Shelf was hidden beneath Antarctica's ice, but its drainage left a mark visible from space as a broad depression that deepened by more than 6 meters (20 feet) at its center.
Public health researchers have long examined how societal forces can shape health outcomes. Decades after redlining was outlawed, for example, researchers continue to document its lasting effects on life expectancy, chronic disease and access to health care resources in many communities.
El Niño is part of a natural climate pattern that occurs roughly every two to seven years, bringing warmer-than-normal water to parts of the equatorial Pacific. The most recent very strong El Niño events, in 1997–98 and 2015–16, upended weather patterns. Impacts spanned the planet, from fires in Indonesia and the Amazon to crop failures due to drought in southern Africa to heavy rain and coastal flooding in Southern California. The current El Niño rivals these past heavyweights.
Human cells hold about two meters (6.6 feet) of DNA, folded and compacted to fit inside a nucleus. That packing is essential for life, but it creates a problem for scientists. Some of the genes that control a cell's identity are buried so deep in tightly packed DNA that gene-targeting tools such as CRISPR activation, or CRISPRa, struggle to reach them.
Young people are facing a future that feels increasingly uncertain. Although every generation experiences turbulence while navigating adolescence, the pressures experienced by Gen Z—those born between 1997 and 2012—are different and seem more pervasive.
A joint research team from KAIST and the APEC Climate Center has found that the East Asian summer front has migrated north over the past half century, with the shift exceeding 200 km (124 miles) in late summer. This raises the risk that the Korean Peninsula will experience heavy rain and heat stress at the same time. The findings suggest that summer disaster planning should address flood prevention and heat-illness management together, through late September.
Deep beneath Japan’s Kikai caldera, a massive magma reservoir is refilling 7,300 years after one of the most powerful volcanic eruptions in Earth's recent geological history. Scientists used underwater seismic surveys to reveal a vast store of magma that appears to have accumulated since the ancient catastrophe. The discovery could help explain how supervolcanoes like Yellowstone and Toba rebuild their magma supplies.
Researchers have uncovered a surprising reason dental implant infections often resist antibiotics: the implants themselves can contribute to the problem. Bacteria corrode titanium implants, releasing microscopic particles that hijack immune cells, trigger destructive inflammation, and accelerate jawbone loss.
A newly FDA-cleared PTSD treatment uses personalized brain mapping and magnetic stimulation to target abnormal brain activity, with a clinical trial reporting a 52% reduction in symptoms and 68% remission. Researchers believe the technology could transform PTSD care and pave the way for more precise treatments for other mental health conditions.
MIT engineers have built a paper-thin swimming robot powered by living muscle cells that respond to flashes of light, allowing it to swim and steer through water. The breakthrough could pave the way for tiny, self-healing biological robots capable of exploring fragile environments that ordinary machines cannot safely navigate.
