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.
Led by Dr. Rui Gomes Coelho, assistant professor of historical archaeology, the research reveals ordinary people's attitudes toward hospitality and solidarity in 20th-century Europe.
Modern agriculture's selective breeding of crops for particular requirements may now be a roadblock to further gains, prompting a trio of senior University of Queensland plant scientists to call for a new way forward.
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.
Quantum systems can occupy superpositions, quantum states that combine different possibilities. For instance, a microwave field can be prepared in a superposition of an empty state and a state that contains microwave light.
A large-scale survey has found cats fed vegan diets had lower rates of obesity and related health problems than those fed conventional meat-based diets.
