Medieval Greenlanders may have chased dwindling walrus herds ever farther north in an effort to maintain their economy, when the value of walrus ivory tanked after the introduction of elephant tusks into European markets in the 1200s.
Angela Harper is a PhD candidate at the Cavendish Laboratory, a member of Churchill College, and a Gates Cambridge Scholar. Here, she tells us about her work in renewable energy, setting up a Girls in STEM programme while she was an undergraduate in North Carolina, and the importance of role models when pursuing a career in STEM.
Flora Donald is a PhD candidate who splits her time between the Department of Plant Sciences and the Centre for Ecology and Hydrology. Here, she tells us about growing up in a family of gardeners, her research on conserving the native UK juniper, and her love of the Scottish Highlands.
People who live in areas of higher than average deprivation are more likely to be admitted to hospital and to spend longer in hospital, according to new research from the University of Cambridge. The difference was particularly pronounced among manual workers and those with lower education level.
Continually logging and re-growing tropical forests to supply timber is reducing the levels of vital nutrients in the soil, which may limit future forest growth and recovery, a new study suggests. This raises concerns about the long-term sustainability of logging in the tropics.
The aquatic larvae of the net-winged midge have the unique ability to move around at ease on rocks in torrential rivers using super-strong suction organs. Powerful modern imaging techniques have now revealed the structure of these organs in intricate detail, providing an insight into how they work so reliably.
Artificial intelligence is being developed that will allow advisory 'quarantining' of hate speech in a manner akin to malware filters – offering users a way to control exposure to 'hateful content' without resorting to censorship.
Mothers’ and babies’ brains can work together as a ‘mega-network’ by synchronising brain waves when they interact. The level of connectivity of the brain waves varies according to the mum’s emotional state: when mothers express more positive emotions their brain becomes much more strongly connected with their baby’s brain. This may help the baby to learn and its brain to develop.
