Scientists to create ‘health and safety’ cow
Gene-editing techniques are being used to create cows that
are born without any horns at all.
By suppressing horn growth, scientists hope to create 'safe'
cows that pose less of a risk to farmers and the general public. Normally,
removing the horns from a regular cow is a difficult and painful process for
the animal. Several workers have been killed and others injured in accidents
involving cows over the last few years. "It would be very positive to create
hornless cows. It would save a lot of time for us and pain for the calf.
Everybody wins," said Mansel Raymond, chairman of the National Farmers'
Union Dairy Board for England and Wales.
The technique involves a new form of genetic engineering
that enables scientists to make precise changes to DNA. "This would be a
major advance in animal welfare," said Professor Geoff Simm.
Researchers are using gene-editing techniques to insert a
DNA patch into the genome of Holsteins, Britain's foremost dairy breed, to suppress
horn growth.

that he accomplished this by his arts, traversed the route, saw the islands,
their people and riches, and, returning, gave certain information of all to
Tupac Inca.
The Inca, having this certainty, determined to go there. He
caused an immense number of balsas to be constructed, in which he embarked more
than 20,000 chosen men; taking with him as captains Huaman Achachi, Cunti
Yupanqui, Quihual Tupac (all Hanan-cuzcos), Yancan Mayta, Quisu Mayta,
Cachimapaca Macus Yupanqui, Llimpita Usca Mayta (Hurin-cuzcos); his brother
Tilca Yupanqui being general of the whole fleet. Apu Yupanqui was left in
command of the army which remained on land.
Tupac Inca navigated and sailed on until he discovered the
islands of Avachumbi and Ninachumbi, and returned, bringing back with him black
people, gold, a chair of brass, and a skin and jaw bone of a horse. These
trophies were preserved in the fortress of Cuzco until the Spaniards came. An
Inca now living had charge of this skin and jaw bone of a horse. He gave this
account, and the rest who were present corroborated it. His name is Urco
Huaranca. I am particular about this because to those who know anything of the
Indies it will appear a strange thing and difficult to believe. The duration of
this expedition undertaken by Tupac Inca was nine months, others say a year,
and, as he was so long absent, every one believed he was dead. But to deceive
them and make them think that news of Tupac Inca had come, Apu Yupanqui, his
general of the land army, made rejoicings. This was afterwards commented upon
to his disadvantage, and it was said that he rejoiced because he was pleased
that Tupac Inca Yupanqui did not appear. It cost him his life.
These are the islands which I discovered in the South Sea on
the 30th of November, 1567, 200 and more leagues to the westward, being the
great discovery of which I gave notice to the Licentiate Governor Castro. But
Alvaro de Mendaña, General of the Fleet, did not wish to occupy them[104].
[Note 104: This story of the navigation of Tupac Inca to the
islands of Ninachumbi and Avachumbi or Hahua chumpi is told by Balboa as well
as by Sarmiento. They were no doubt two of the Galapagos Islands. Nina chumpi
means fire island, and Hahua chumpi outer island. See my introduction to the
Voyages of Sarmiento, p. xiii; and Las Islas de Galapagos by Marco Jimenes de
la Espada.]
