Genetics of a canine transmissible tumour show how the world’s oldest cancer “metastasised” through the global dog population – and captured, maintained and rearranged its mitochondrial DNA along the way.

Cambridge University Library is celebrating its 600th anniversary with an exhibition of priceless treasures communicating 4,000 years of human thought. To celebrate, we have made six films on the six distinct themes featured in Lines of Thought. The second film in the series looks at Gravity; by following the discussions of generations of great scientific minds, from Copernicus to Hawking via Newton and Einstein, we begin to understand our place among the stars. To see more of the exhibits in this theme, visit the Virtual Exhibition: https://exhibitions.lib.cam.ac.uk/linesofthought/case/gravity/

From 3000-year-old Chinese oracle bones to Penguin paperbacks of the 20th century, the collections at Cambridge University Library chart the technological revolutions that have changed the world around us.
The objects in the film all feature in the Library's spectacular new exhibition Lines of Thought: Discoveries that Changed the World

Research provides insight into feasibility of virus becoming airborne transmissible.
It might be possible for human-to-human airborne transmissible avian H5N1 influenza viruses to evolve in nature, new research has found.
Currently, avian H5N1 influenza, also known as bird flu, can be transmitted from birds to humans, but not (or only very rarely) from human to human. However, two recent papers by Herfst, Fouchier and colleagues in Science and Imai, Kawaoka and colleagues in Nature reveal that potentially with as few as five mutations (amino acid substitutions), or four mutations plus reassortment, avian H5N1 can become airborne transmissible between mammals, and thus potentially among humans. However, until now, it was not known whether these mutations might evolve in nature.
The Cambridge researchers first analysed all of the surveillance data available on avian H5N1 influenza viruses from the last 15 years, focusing on birds and humans. They discovered that two of the five mutations seen in the experimental viruses (from the Fouchier and Kawaoka labs) had occurred in numerous existing avian flu strains. Additionally, they found that a number of the viruses had both of the mutations.

Britain has had a long history of interaction with India from the 17th century until the present day. During that time, a large number of Britons who lived in the region documented their lives using diaries, letters and photos, many of which have found their way into the archive of the Centre of South Asian Studies in Cambridge.

Howler monkeys are about the size of a small dog, weighing around seven kilos, yet they are among the loudest terrestrial animals on the planet, and can roar at a similar acoustic frequency to tigers.
Evolution has given these otherwise lethargic creatures a complex and powerful vocal system. For males, a critical function of the roar is for mating: to attract females and scare off rival males.
But not all male howler monkeys have been equally endowed. The bigger a male howler’s vocal organ, and the deeper and more imposing roar they possess, the smaller their testes and the less sperm they can produce.
Dr Jacob Dunn from Cambridge's Division of Biological Anthropology describes this evolutionary 'trade-off' and how it relates to Darwin's work on sexual selection.

The Cambridge Animal Alphabet series celebrates Cambridge's connections with animals through literature, art, science and society. Here, J is for Jay – a surprisingly clever corvid with the ability to mimic human voices and much more.
Jays are corvids – members of the crow family. The jays we see in Britain are Eurasian jays. With their pinkish plumage, and characteristic flash of blue, they will be familiar to many people as woodland birds that are increasingly seen in gardens, even in cities.
Professor Nicky Clayton (Department of Psychology) has carried out pioneering research into the thinking power of corvids. Her observations have revealed these crows to be extremely clever. In Aesop’s Fables, the wise old crow drops pebbles into a pitcher of water to raise the level and allow her to drink. Clayton’s work has revealed that real-life crows can, if they need to, use pebbles in just this way.

This set of 29 papier mache models of horses' teeth (Wh. 6135) was made by Dr Louis Auzoux in France in the 1890s. The original wooden case opens out to reveal four rows of spaces for sets on each side. A hinged wooden flap holds the teeth in place. The models demonstrate the appearance of horses’ teeth at different ages, the effects of wind sucking and crib biting, and the fraudulent ways of making a horse seem older or younger by the appearance of its teeth.
As a medical student in Paris, Auzoux noticed that there was often a shortage of human remains available for dissection. To deal with the shortage of bodies, he began producing accurate anatomical models that could be taken apart piece by piece. With financial support from the French state, Auzoux founded a factory for producing anatomical models. The models became a commercial success and were used by schools, universities and hospitals, as well as by private individuals who could rent models at low costs. Responding to changing trends in scientific research and education, the company branched out and began producing models of human embryos, animals and plants.
The horses’ teeth are on display in the Main Gallery of the Whipple Museum of the History of Science.
The museum is open Monday to Friday 12:30-4:30pm. The Museum is not always open during University vacations and visitors are advised to check beforehand. Admission is free.
