'Super-puff' planets lighter than candy floss discovered by international team

An international collaboration has discovered two of the lowest-density giant planets ever detected: rare "super-puff" planets with densities lower than candy floss. The study—led by the University of Oxford, in collaboration with Université Côte d'Azur/Observatoire de la Côte d'

Laser experiments push helium to record shock pressures

Deep inside gas giants like Jupiter and Saturn, hydrogen and helium coexist under pressures millions of times greater than Earth's atmosphere. Under those conditions, helium may separate from hydrogen and influence a planet's internal heat flow, structure and magnetic field. Unde

A NASA satellite caught a giant tsunami doing something no one expected

A Pacific-wide tsunami triggered by a magnitude 8.8 Kamchatka earthquake gave scientists their first detailed satellite view of a major tsunami in motion. The observations revealed unexpected wave behavior and helped uncover a larger earthquake rupture than earlier models predict

Why climate change could make staple crops less nutritious—and how CRISPR may help

At present, more than 700 million people live with caloric hunger, and more than 2 billion suffer from micronutrient deficiencies, known as "hidden hunger." By prioritizing high yield over nutritional quality, global calorie production has increased while exacerbating vitamin and

Sponges may cut methylmercury contamination in marine food webs by more than 50%

Marine sponges may play an important, previously underestimated role in reducing methylmercury contamination in marine food webs. In a new modeling study, researchers at Helmholtz-Zentrum Hereon showed that sponges can significantly influence the spread of this environmental toxi

Ultra-precise technology can count damaged DNA fragments

The Korea Research Institute of Standards and Science has developed an ultrasensitive immunoassay-based analytical platform that can detect and quantify trace amounts of "Small Excised Damaged DNA (sedDNA)" fragments generated during cellular DNA repair. This technology enables h

Plankton-linked vapors could speed cloud seed formation over cold oceans

For nearly 50 years, scientists have suspected that microscopic marine plankton play a role in cloud formation over the oceans. Now, an experiment led by the University of Helsinki suggests that it may be more important than previously thought. The findings are published in the j
