UK Government ‘must grow demand for green hydrogen’, says industry body
by
-
Aberdeen: The report recommends coordinated action to grow demand for green hydrogen in difficult-to-decarbonise sectors such as maritime operations. Scotland has the potential to be a major global producer of green hydrogen but the UK Government must rapidly step up its support for the sector, says a report published today (4 December) by industry body […]

A smarter way for large language models to think about hard problems
by
To make large language models (LLMs) more accurate when answering harder questions, researchers can let the model spend more time thinking about potential solutions. But common approaches that give LLMs this capability set a fixed computational budget for every problem, regardless of how complex it is. This means the LLM might waste computational resources on simpler […]

MIT engineers design an aerial microrobot that can fly as fast as a bumblebee
by
In the future, tiny flying robots could be deployed to aid in the search for survivors trapped beneath the rubble after a devastating earthquake. Like real insects, these robots could flit through tight spaces larger robots can’t reach, while simultaneously dodging stationary obstacles and pieces of falling rubble. So far, aerial microrobots have only been […]

Helping power-system planners prepare for an unknown future
by
A new computer modeling tool developed by an MIT Energy Initiative (MITEI) research team will help infrastructure planners working in the electricity and other energy-intensive sectors better predict and prepare for future needs and conditions as they develop plans for power generation capacity, transmission lines, and other necessary infrastructure. The tool could reduce the amount […]

CIEH responds to UK Government’s revised Environmental Improvement Plan
by
Over 90 % of the “very high air-pollution neighbourhoods” in England fall within London, according to a 2025 Friends of the Earth analysis. The UK Government’s publication of a revised 25-year Environmental Improvement Plan (EIP) has been broadly welcomed by the Chartered Institute of Environmental Health (CIEH), although the group appeared to take issue with […]

Your Summary of Negotiations: Dec. 3
The 2025 UN Climate talks, COP30, finished on Saturday, November 22nd, following talks (unsurprisingly) being pushed into overtime. COP30, billed as the COP of truth and implementation, the forest COP, and the Amazon COP, failed to include any language in its final decision committing to a fossil fuel phase-out. At the heart of COP30’s discord […]

Analysis: Why COP30’s ‘tripling adaptation finance’ target is less ambitious than it seems
One of the headline outcomes to emerge from COP30 was a new target to “at least triple” finance for climate adaptation in developing countries by 2035. Vulnerable nations stress that they urgently need to strengthen their infrastructure as climate hazards intensify, but they struggle to attract funding for these efforts. The new goal, which builds […]

Reflecting on COP30
As it is my first COP, I walked in with quite the optimism, the hope that I would see some new things. And though I did, simultaneously the same framework I had long recognized replicated itself in front of me. The false carpet floors sat three inches above concrete, Indigenous Peoples and Afrodescendant panels were […]

New control system teaches soft robots the art of staying safe
by
Imagine having a continuum soft robotic arm bend around a bunch of grapes or broccoli, adjusting its grip in real time as it lifts the object. Unlike traditional rigid robots that generally aim to avoid contact with the environment as much as possible and stay far away from humans for safety reasons, this arm senses […]

Asia-Pacific faces ‘$500bn-a-year’ hit from rising seas if current policies continue
Coastal flooding could bring $500bn of annual damages to the Asia-Pacific by the year 2100, if countries do not adapt to rising sea levels. This is according to new research, published in the journal Scientific Reports, which assesses how coastal flooding is impacting the Asia-Pacific region – and models how the damages could worsen as […]
