Decades ago, one of the world’s largest subpopulations of nesting eider ducks spent its summers on tiny Mitivik Island, near the mouth of Hudson Bay.

A new study suggests that most of Earth’s carbon originated in the outer solar system and didn’t arrive here until the late stages of planetary development.

Data centres at the heart of the artificial intelligence (AI) revolution could be cooled more effectively and economically with a hybrid system under development at the University of Waterloo that targets hotspots on computer chips with a single drop of boiling coolant.

In agriculture, innovation has to do more than look promising on paper. It has to work in the field.

The UK has seen great progress toward decarbonisation with 63% of electricity now low-carbon, especially thanks to wind and nuclear, supported by hydro, solar and biomass.

Norway has the technology and expertise needed to develop high-speed catamarans capable of operating even the longest routes. But something is missing.

Ocean currents move water around the globe in a vast circulation system.

Among the technical inquiries spanning topics like cyclodextrin polymers and mass spectrometry that were stacked in Damian Helbling’s inbox was a question about four golden retrievers.

A collaboration between researchers at Cornell and City University of Hong Kong has produced a new computational tool that could help overcome one surprisingly persistent obstacle to the efficient production of so-called green hydrogen: bubbles.

Green hydrogen, produced by splitting water using electricity from renewable sources, offers a promising alternative to fossil fuels, particularly for industries such as steelmaking and chemical manufacturing.

The researchers developed a computer model that reveals how bubbles forming during water electrolysis interfere with the process and increase the energy required to produce hydrogen. Their findings, published Nov. 9 in the journal EES Catalysis, identify a critical bubble size beyond which energy losses increase dramatically, providing a potential roadmap for designing more efficient hydrogen-producing equipment.

Antarctic blue whales appear to be creeping back from the brink of extinction after 50 years of protection. A new study estimates the total population at 4,018, up from 418 after the last reported whale catch in 1973.
