Review examines why children often receive medicines outside official labels

This review examines off-label prescribing in children, meaning medicines used outside the terms of their official approval. It argues that such prescribing is not automatically inappropriate, but that its acceptability depends on the available evidence, the clinical setting, and safety monitoring. The article also describes continuing delays, incomplete studies, and a lack of suitable child-specific formulations.

Herring supplied more than half the energy some B.C. humpbacks needed

Herring supplied more than half of the estimated annual energy needs of non-reproductive and pregnant female humpback whales, as well as juvenile and adult males, in an eastern British Columbia feeding ground. Juvenile and lactating females obtained between 25% and 50% of their estimated needs from herring.

A child’s hydrocephalus shunt migrated into the chest, causing recurring lung collapse

A five-year-old child developed repeated right-sided tension pneumothorax after receiving a ventriculoperitoneal shunt for hydrocephalus. A contrast study showed an abnormal connection between the shunt and the bronchial tree; chest drainage and repositioning the shunt were followed by rapid improvement.

After a tsunami, stickleback hybrids quickly lost much of their foreign DNA

A tsunami in Japan created new habitats where freshwater and marine sticklebacks hybridized. Genomic monitoring over nine years found that marine DNA was rapidly removed from most of the hybrid population, including regions linked to reproductive isolation.

Alaska gas-hydrate test exposes failures in pumps and sand control

A 10-month gas-hydrate production test on Alaska’s North Slope produced gas at a stable rate for 60 days. But pump failures and problems with the system meant to keep sand out of the well limited depressurization and productivity, providing design lessons for future tests.

An AI system matched gold-medal-level performance on 2025 math olympiad problems

Aristotle, an AI system for automated theorem proving, achieved gold-medal-equivalent performance on the 2025 International Mathematical Olympiad problems. It paired informal reasoning with formal proof checking, including a dedicated tool for geometry problems.

Farm lime absorbed more carbon than it released in the Mississippi basin

Agricultural lime is generally counted as a source of carbon dioxide, but a study of the Mississippi River Basin finds that it acted as a net carbon sink over the past century. River records indicate that about 90% of the lime’s ideal carbon-removal potential was realized, equivalent to approximately 0.44 gigatonnes of carbon dioxide.

Sheep wool carried benzophenones that may reach people through wool products

A study of raw wool from 50 sheep near Bishkek, Kyrgyzstan, found benzophenone contaminants in every sample. The results suggest that wool can retain these chemicals over a sheep’s lifetime and may provide an indirect route of human exposure through wool products.

How Greek engineers shaped Apollonia into Cyrene’s harbor

A study of Apollonia, Cyrene’s harbor on Libya’s coast, reconstructs how early Greek engineers adapted natural rock ridges and small islands into a working port. It also finds that tectonic movements changed the shoreline and submerged much of the harbor, making its remains harder to interpret.

In Saudi Arabia, AI-guided building controls cut electricity use in desert heat

An adaptive AI control system cut electricity use by 37.8% compared with conventional thermostats in eight occupied buildings in Hail, Saudi Arabia. It kept indoor conditions within the study’s comfort range for most occupied hours and increased savings during dust storms.

After a heatwave, Baja California reefs support fish and people unequally

A study of temperate kelp forests along 600 kilometers of Baja California found that reef states after the 2014–2016 marine heatwave supported very different contributions to ecosystems and people. Reefs with persistent canopy-forming kelp generally supported more fish biomass, ecological functions and nutritional supply than simplified reefs.

In Ghanaian schools, hairstyle rules shape identity and belonging

Research in Ghana’s Greater Accra Region finds that school hairstyle rules regulate more than appearance: they also shape how students experience discipline, recognition and belonging. Students responded through compliance, adaptation, negotiation and resistance, including resistance to expectations around straightened hair.

Fruit-based packaging changed color as refrigerated beef freshness declined

Researchers developed a food-packaging aerogel containing Rosa canina fruit extract and magnesium oxide-doped carbon dots. It changed color from light khaki to dark violet while monitoring refrigerated raw beef for five days, suggesting a visible way to track freshness.

In Zimbabwe, young people with disabilities help shape climate adaptation

More than 30 young people with disabilities in Harare took part as co-researchers in a study of climate adaptation and disability. Through storytelling, mapping and group discussions, they challenged exclusionary views and developed ideas including community-led data systems, accessible communication and youth-led advocacy.

Waste-based cement materials can store energy, but carbon additives weaken them

Researchers made cement-based structural electrodes partly from industrial solid waste and added either graphene nanoplatelets or carbon nanotubes. Both additives greatly increased energy-storage capacity, but they also reduced compressive strength, creating a tradeoff between storing energy and supporting loads.
