COP30 ended in Belém on 22 November with a large finance package to mobilise US$1.3 trillion a year by 2035, but delegates did not secure clear commitments to cut fossil fuel use. Talks saw a pavilion fire and ongoing debates on implementation.
A lab study found that smoking hemp plus eating a processed, seed‑oil–rich diet may weaken the immune system and increase inflammation and heart damage. Researchers saw cannabis compounds build up in several organs.
New lithium finds in Nigeria have drawn Chinese investment. Since September 2023 Chinese firms have poured money into processing, while Nigeria pushes local processing and activists warn about unsafe artisanal mining.
Study of Ngogo chimpanzees in Uganda finds that killing neighbouring groups and expanding territory led to more births and much better infant survival in the three years after expansion.
Young people across Asia and Africa use digital tools to organise fast, decentralised protests. Examples include Nepal in 2025 and unrest in Madagascar; regional reports note pressure on civil society in several countries.
New research shows gas bubbles can form in magma because of shear inside volcanic conduits. Bubbles may join to make channels that let gas escape early, producing calm flows in some volcanoes.
Two recent studies compared grouping English learners together in school classes. A high school study of 31,303 students linked higher EL concentrations to lower graduation and college entry; an elementary trial found no overall difference but different benefits by skill level.
Researchers at the University of Pittsburgh made a wearable biosensor that detects antibodies in interstitial fluid in 10 minutes without a blood draw. The tiny carbon nanotube sensors are highly sensitive and the work appears in Analytical Chemistry.
During COP30 in Belém (10–21 November 2025) RADD held a forest immersion on 17 November 2025 in Cameroon. The event connected women, local forest knowledge and global climate debates and included training, planting and exchanges.
A study in Nature Communications compared alternative splicing across 26 mammal species (lifespans 2.2–37 years) and found splicing patterns better predict maximum lifespan than gene activity; the brain shows many lifespan-linked events controlled by RNA-binding proteins.
New evidence suggests the Band of Holes at Monte Sierpe in southern Peru was part of a pre‑European Indigenous system for accounting and exchange. Researchers used sediment analysis and drone images to reach this conclusion.
Researchers report a biodegradable microneedle patch that delivers interleukin-4 to injured heart tissue. The local treatment encourages healing immune cells, reduces scarring, and may improve heart recovery while avoiding systemic side effects.
