image: Large-scale patterns in lake dissolved organic matter driven by nutrients and climate view more Lakes, often called the 'lungs of the land,' play a fundamental role in the global carbon cycle, acting as significant reservoirs of dissolved organic matter (DOM) and sources of greenhouse gases.

video: Video showing the feeding behavior of juvenile shrimp under a simulated microgravity environment generated by a newly developed high-speed clinostat. The modified clinostat rotates rapidly enough to prevent aquatic animals from regaining their normal posture, enabling long-duration observation of feeding behavior under simulated microgravity conditions.

image: Fig. (a) clusters arranged according to size; (b) keywords for the top 10 clusters arranged horizontally on the timeline view more China faces serious earthquake risks because of its location between major active seismic belts. As a result, seismic risk management has long been a major concern for government agencies, researchers, engineers, and communities.

image: U. of I. engineers Paul Rozzi, professor Kyle Smith and Jeong Le have developed a new battery-type device that captures CO2 from the air. view more CHAMPAIGN, Ill. — Engineers have developed a new way to pull carbon dioxide directly from the atmosphere using a process similar to charging and discharging a battery — an advance that could help address the planet’s excess CO2 problem.

image: These brain maps show infant (left) and adult (right) brain activity for differentiating speech sound location from noise. Red indicates  noise more activity, and blue indicates less activity. view more In noisy environments, organisms differentiate sounds they want to detect from interfering noise to improve their perception of target sounds. This process is widely conserved across species, including birds, crocodiles, ferrets, and human adults.

image: Holgate Glacier calves near Seward, Alaska. view more Melting and breaking icebergs in the far-off, northeastern region of the Pacific Ocean can weaken a massive current system in the Atlantic Ocean, according to a University of California, Davis study published in Nature Communications. The Atlantic Meridional Overturning Circulation, or AMOC, regulates the global climate by acting as a massive conveyor belt, moving warm, salty water from the tropics to the North Atlantic.

image: Number of drought-related news articles, counts of negative and positive news articles, and water-saving rates in the metropolitan and rural areas. view more As climate change increases the risk of severe droughts, water resources management is an urgent challenge. Drought develops slowly, which makes the public aware of the ongoing drought. Governments rely on the media to communicate drought risks and encourage water conservation.

The NF‑κB family is a master regulator of innate and adaptive immunity. Its aberrant activation—via canonical or non‑canonical pathways—drives chronic inflammation, autoimmunity, allergies, and primary immunodeficiencies/autoinflammatory syndromes. This review synthesizes the molecular architecture, ubiquitin‑based relay systems, and dynamic regulation of NF‑κB, highlighting its dual pathways, roles in immune responses, cell survival, and development.
