Neil Robertson calls for ban on Ronnie O’Sullivan’s chalk: ‘All the players hate it’

Neil Robertson calls for ban on Ronnie O’Sullivan’s chalk: ‘All the players hate it’

Published by Sam Flores

Neil Robertson has called for a ban on the chalk used by Ronnie O’Sullivan during the World Snooker Championship, claiming that “all the players hate it” and suggesting it causes problems on the baize. O’Sullivan’s hopes of a record eighth world title at the Crucible were ended by old rival John Higgins in a 13-12 thriller on Tuesday, with Robertson beating Chris Wakelin in the evening session to set up a meeting with the Scot. Higgins suffered a notable kick in the deciding frame while potting a red, and subsequently ran out of on the next black, though held on to knock out O’Sullivan. Chalk marks were also evident during the match on the table. O’Sullivan is one of only a handful of players on the World Snooker Tour (WST) to still use the traditional Triangle Chalk. While almost all players use Taom Chalk, which reduces kicks and leaves no marks on the table, there are no restrictions in events on the type used. Robertson, though, admitted he was glad to avoid a meeting with …

On the shoulders of giants: roaming among England’s famous chalk figures | Walking holidays

In the churchyard next to Wilmington Priory in East Sussex, I found a yew so ancient and stooped that its trunk had eaten half a gravestone. Its boughs were supported by long poles, a creepy sight that made me shudder. I had come here to see something just as strange, but more benign than this folk-horror vision – the figure of the Long Man of Wilmington on the hillside opposite, on the steep scarp of the South Downs. He treks over the hill, a stave clasped in each hand. Climbing Windover Hill, just beneath the South Downs Way, I saw that while he was once a chalk giant, his lines are now marked with concrete blocks. The Guardian’s journalism is independent.

The Long Man may be Anglo-Saxon in origin – the shape is similar to the design on a buckle discovered in Kent in 1964 by the archaeologist Sonia Chadwick Hawkes, which probably represents the god Odin (or Woden); but he …

Traces of Leonardo da Vinci’s DNA May Have Been Discovered on a Red Chalk Drawing Called ‘Holy Child’

Traces of Leonardo da Vinci’s DNA May Have Been Discovered on a Red Chalk Drawing Called ‘Holy Child’

Published by skeptic

Researchers from the Leonardo da Vinci DNA Project (LDVP) that by analyzing the drawing of Holy Child and other Renaissance artifacts, such as letters written by a da Vinci relative, they have recovered some Y chromosome DNA sequences that appear to belong to a genetic group of people with common ancestors in Tuscany, where the genius and Renaissance master was born in 1452. The findings, first reported in Science, could be the first time scientists have identified DNA from da Vinci himself. The DNA Historical artifacts can accumulate DNA from the environment and potentially offer useful information about the people who created and handled them. Gathering that material on such precious objects without damaging or contaminating them, though, is a complex challenge. Today, decisions about the authorship of a work depend on expert opinion—for example, on how a brushstroke was created. The LDVP researchers therefore used an extremely gentle swabbing method to attempt to collect biological material. They then extracted small amounts of DNA, which provided useful information. “We recovered heterogeneous mixtures of non-human DNA,“ …
