Mount Kilimanjaro in Tanzania is sold to the world as frozen romance and pure nature. But the real story today is at its feet, not its peak.
Phys.org / The UN climate talks have become too big for their own good
If you're still heading to this year's UN climate conference in Belém, Brazil, I hope you booked early. Hotels long sold out, and latecomers face extortionate rates—or the prospect of lodging in a dubious "love hotel."
Phys.org / In Kyrgyzstan, world's largest natural walnut forest thins away
Rustling through fallen golden leaves, locals in a forest outside Arslanbob in the Kyrgyz mountains were scurrying for walnuts—an ancient pastime and economic lifeline for the region.
Phys.org / New deployable structures could help astronauts maintain muscle mass in space
From muscle atrophy to bone loss, astronauts face a number of health risks while in space.
Phys.org / Bold new investment fund to channel billions into tropical forest protection—one key change can make it better
The world is losing vast swaths of forests to agriculture, logging, mining and fires every year—more than 20 million acres in 2024 alone, roughly the size of South Carolina.
Phys.org / How five countries are adapting to the climate crisis
Countries around the world are facing worsening heat waves, hurricanes, droughts and floods. If current trends continue, governments need to prepare for a much hotter world with a predicted increase in global temperatures ...
Phys.org / Land is Africa's best hope for climate adaptation: It must be the focus at COP30
Agriculture, forestry and other land uses together account for about 62% of Africa's greenhouse gas emissions. At the same time, land degradation, deforestation and biodiversity loss are eroding Africa's resilience.
Phys.org / Exploring the origin of a distant Type Ibn supernova found far from its host galaxy
An international team of astronomers has performed photometric and spectroscopic observations of a distant Type Ibn supernova known as SN 2024acyl. Results of the observational campaign, published November 6 on the arXiv ...
Phys.org / Unified model may explain vibrational anomalies in solids
Phonons are sound particles or quantized vibrations of atoms in solid materials. The Debye model, a theory introduced by physicist Peter Debye in 1912, describes the contribution of phonons to the specific heat of materials ...
Tech Xplore / Novel smart fabrics give robots a delicate grip
Robots aren't always the most delicate of machines when handling fragile objects. They don't have the lightness of touch of humans. But that could be about to change thanks to a new development in smart materials.
Phys.org / Qu-based brewing in Bronze Age China: Pottery residue offers insights into Mogou mortuary rituals
In a study by Dr. Yinzhi Cui and his colleagues published in the Journal of Archaeological Science: Reports, the contents of 42 pottery vessels from the Bronze Age site of Mogou were analyzed.
Phys.org / 100 years of menus show how food can be used as a diplomatic tool to make and break political alliances
Food brings people together. It serves as a tool to communicate political stances, to cultivate cross-cultural comprehension or, if necessary, create tensions. Menus can reflect these intentions by using food to create specific ...
