- Major funding to support next generation of biology and environmental researchers 14 November 2024 The University of Bristol will be among the beneficiaries of £36m in funding announced today [13 November] to support the next generation of researchers across the South West and Wales aiming to solve some of the most pressing challenges around environmental change and biology.
- Gardens prevent pollinators from starving when farmland nectar is scarce, new study finds 23 October 2024 Gardens offer a steady and reliable source of nectar all year round, helping to keep pollinators fed when farmland sources are limited, researchers have discovered.
- Butterfly brains reveal the tweaks required for cognitive innovation 18 October 2024 A species of tropical butterfly with unusually expanded brain structures display a fascinating mosaic pattern of neural expansion linked to a cognitive innovation.
- Replacement crop treatment not safe for important pollinator, experts say 6 September 2024 A novel pesticide thought to be a potential successor to banned neonicotinoids caused 100% mortality in mason bees in a recent test.
- Increased threat of war enhances pup survival 16 November 2023 Animal offspring may survive better when their groups are in greater conflict with rival factions, research from the University of Bristol has shown for the first time.
- Tom Pitman Retirement 9 November 2023 Tom Pitman, our GroDome manager, has eventually decided to hang up his green labcoat and secateurs and head for his own potting shed, joining the community of the retired.
- Universal epigenetic clocks provide insights into why mammals are ‘born to die’ 7 November 2023 Benjamin Franklin famously stated ‘in this world nothing can be said to be certain, except death and taxes’. But why are we ‘born to die’ and what mechanisms underpin the gradual decline in biological functions (senescence) in living organisms, and ultimately their death? We are at an exciting point in ageing research: a Universal Mammalian Clock Chip has been developed using data on DNA methylation (DNAm) from a wide range of mammals and tissue types to predict the chronological age of any mammal species accurately from a single equation, also showing how DNAm changes in predictable ways over an animal’s life. Two new papers1,2 provide remarkable insights into ageing. The findings reveal great potential for estimating a mammal’s chronological age when it is not known, for understanding why some individuals age faster than expected for their chronological age, and for understanding factors affecting the large variation in the lifespans of different mammal species.
- Static electricity attracts ticks to hosts, scientists find 1 November 2023 Ticks can be attracted across air gaps several times larger than themselves by the static electricity that their hosts naturally accumulate, researchers at the University of Bristol have discovered.
- Warmer and murkier waters favour predators of guppies, study finds 27 July 2023 Changes in water conditions interact to affect how Trinidadian guppies protect themselves from predators, scientists at the University of Bristol have discovered.
