An attosecond (10⁻¹⁸ seconds) corresponds to the natural timescale of electron motion in matter. In 2023, the Nobel Prize in Physics recognized experimental methods for generating and measuring attosecond light pulses, highlighting their ability to effectively “film” electrons in real time. The next frontier of attosecond science is extending these capabilities into the X-ray regime. X-rays provide element specificity and atomic-scale sensitivity, making them powerful probes of ultrafast dynamics in complex materials and chemical systems. However, generating high-power attosecond X-ray pulses at high repetition rates remains a major challenge.

A research team has uncovered a hidden layer of early growth control in mung bean by identifying a large set of previously unknown microRNAs and showing how they help shape seedling development. 

A new study reveals that not all biochar works the same way in agriculture. The size of biochar particles can significantly influence how well crops grow, especially in salt-affected soils that challenge global food production.

A new study reveals that combining biodegradable microplastics with biochar may offer an unexpected solution to one of agriculture’s most persistent problems: toxic metal contamination in food crops.

A new study reveals that turning crop residues into biochar can significantly enhance soil carbon storage compared to simply returning straw to the field. The findings provide fresh insights into how different farming practices influence the stability of soil organic carbon, a critical factor for climate mitigation and sustainable agriculture.

A new long-term field study reveals that biochar and crop residues help soils store carbon in fundamentally different ways, offering new insights for climate-smart agriculture and carbon sequestration strategies.

Emerging contaminants are rapidly becoming a global environmental challenge, posing risks to soil health, water quality, and human well-being. A new comprehensive review reveals that biochar, a carbon-rich material derived from biomass, may offer a sustainable and highly effective solution for removing these pollutants from the environment.

Korea University College of Medicine (Dean: Sung Bom Pyun) successfully held the 8th KU International Medical Student Research Conference from December 19 to December 20, 2025 at the First Medical Building of Korea University College of Medicine.

Peach buds may be far less dormant than scientists once believed. 

Embryo transfer (ET) is the final step in in vitro fertilization (IVF) treatment. Beyond embryo quality and endometrial receptivity, ET also considerably affects embryo implantation success. However, the fundamental ET procedure has remained largely unchanged since it was first described by Edwards et al. Due to variations in practice patterns across countries and the lack of a standardized ET protocol, achieving a consensus on the determinants of successful ET remains challenging. Therefore, investigating the association between specific ET characteristics and clinical outcomes is imperative.
