Scurvy's skeletal fingerprint found in California's Late Holocene archaeological sites

Identifying and analyzing climate risks is a necessary function of governments, but researchers at Adelaide University's Environment Institute argue such processes will not lead to effective action without taking additional steps to understand which risks are considered unacceptable by the community and prioritizing responses accordingly.

In early phases of drug development, new active substances are tested in animals—alongside numerous other experimental methods. Researchers face a dilemma: on the one hand, for ethical reasons, they aim to keep the number of animals used in an experiment as low as possible. On the other hand, animal experiments must include enough animals to produce reliable and representative results, for example, to determine whether a new drug candidate produces a specific effect.

Written by Michelle Minitti, MAHLI Deputy Principal Investigator Earth planning date: Friday, May 8, 2026 While we know the monikers Ingenuity and Perseverance are attached to our sister helicopter and rover on the Mars 2020 mission, those characteristics were in full force with Curiosity over the past week. The science we achieved this week was […]

Researchers led by Dr. Changmin Ahn and Prof. Jungwon Kim at KAIST, in collaboration with Prof. Hansuek Lee, have demonstrated a chip-scale photonic approach for generating ultralow-noise and highly stable microwave and millimeter-wave signals based on optical frequency combs (microcombs), offering a potential pathway toward compact, high-performance frequency sources for next-generation technologies.
