Animal pollinators support the production of three-quarters of the world’s food crops, and many flowers produce nectar to reward the pollinators. A new study using bumblebees has found that the sweetest nectar is not necessarily the best: too much sugar slows down the bees. The results will inform breeding efforts to make crops more attractive to pollinators, boosting yields to feed our growing global population.
Around 90% of the resources we process to create goods are not reaching the person for whom they are made. How can we make manufacturing more sustainable?
River flow is reduced in areas where forests have been planted and does not recover over time, a new study has shown.?Rivers in some regions can completely disappear within a decade. This highlights the need to consider the impact on regional water availability, as well as the wider climate benefit, of tree-planting plans.
Material falling into a black hole casts X-rays out into space – and now astronomers have used the echoes of this radiation to map the dynamic behaviour and surroundings of a black hole itself.
Leaving school and getting a job both lead to a drop in the amount of physical activity, while becoming a mother is linked to increased weight gain, conclude two reviews published today and led by researchers at the University of Cambridge.
Students and teachers across India now have free access to a new curriculum on water security and sustainability, co-developed by researchers at the University of Cambridge, which incorporates engagement with climate change and climate activism into their lessons.
A major experiment introducing proactive policing to Underground platforms finds that short bursts of patrolling create a 'phantom effect': 97% of the resulting crime reduction was during periods when police weren’t actually present.?
Agnieszka S?owik is a PhD candidate in the Department of Computer Science and Technology, where she is a member of the artificial intelligence research group. Here, she tells us about neural networks and how they communicate with each other, the importance of supportive supervisors, and how to be a supportive team member.
