Phys.org / We need to talk about our fossil fuel addiction: UNEP chief
"Off Target," "Broken Record," "Closing Window": the UN Environment Program's flagship reports have been warning for years that emissions must fall faster to avoid dangerous climate impacts—but is the world listening?
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 / ALMA resolves close companion orbiting giant red star
Close companions can influence stellar evolution in many ways. While some companions can be detected around young stellar objects, direct observational evidence of companions around asymptotic giant branch (AGB) stars or ...
Phys.org / Axial Seamount experiment to test real-time eruption forecasts
Currently, scientists struggle to forecast volcano eruption events, as no universally reliable, real-time eruption forecasting framework is available. Instead, researchers often rely on retrospective analysis to evaluate ...
Phys.org / How plants decide when to flower: Scientists discover a phosphorus-responsive switch
Phosphorus, a key ingredient in fertilizers, is running out. The world's food systems depend on phosphorus mined from limited reserves, yet much of what is applied to fields washes away, leaving soils increasingly depleted. ...
Phys.org / Controlling triple quantum dots in a zinc oxide semiconductor
Quantum computers have the potential to solve certain calculations exponentially faster than a classic computer could, but more research is desperately needed to make their practical use a reality. Quantum computers use a ...
Phys.org / Smarter magpies linked to social network connections
The social interactions Western Australian magpies experience in their first year of life affects their intelligence, according to a new study.
