正文(英文) | ![]() ![]() Here’s a batch of fresh news and announcements from across Imperial. From a new plea to stop irreversible climate change, to new citizen-science resources focusing on protecting pollinators, here is some quick-read news from across the College. 50% carbon cut critical by 2030
The international 50:30 group includes scientists from the Grantham Institute – Climate Change & the Environment and a few governments on track for the essential reductions. Although most countries pledged carbon neutrality by 2050, and declared a “planetary emergency”, a report from the United Nations Framework Convention on Climate Change showed virtually none are taking meaningful steps to achieve this. Impacts of higher temperature and CO2 levels will trigger global cryosphere changes irreversible on human timescales, including: sea-level rise; severe polar ocean acidification lasting 50,000 years; loss of glaciers for many centuries; and carbon emissions from melting permafrost lasting up to two centuries. Electromagnetic amplification
Superconductors are materials that conduct electricity with no resistance that can repel magnets by expelling magnetic LOF, compressing them and hence increasing their energy density. Researchers at Imperial wondered if this mechanism could be applied at higher frequencies, for electromagnetic wave amplification. They propose a time-dependent system, where a local modulation of the refractive index moves through a material at close to the speed of light, trapping the LOFs of any radiation present and compressing them, ultimately ejecting them as a train of sharp, intense pulses.

The ten finalists in this year’s competition include a bio-tampon for cancer detection, a device for reading multiple lines of braille and a remote foot-care device to prevent diabetic foot ulcers. In June, the ten finalists will be whittled down to five, who will then battle it out at the competition’s grand final on Friday 25 June for their chance to win a share of the £30,000 prize fund. Find out more about this year’s projects in the WE Innovate virtual pitchbook. Protecting pollinatorsStudents, teachers, and scientists across the UK and Italy have joined forces to launch a new series of citizen-science resources focusing on pollinators, such as bees and butterflies. The X-Polli:Nation project, which includes researchers from the Centre for Environmental Policy at Imperial, includes a new survey, online courses, AI tools, and downloadable activity sheets, with plans for more surveys and competitions in the future. The project is funded by the EPSRC and National Geographic, and aims to raise awareness of environmental issues facing pollinating insects, collect data on their feeding preferences for science, plant habitats to support them, and find new ways to communicate their importance to a wider community. X-Polli:Nation will encourage participants to create, maintain and monitor pollinator-friendly habitats and act as pollinator stewards in society.
