Brushing your teeth at least three times a day could lower the risk of heart failure by more than 10 percent, a study has found.

Researchers linked it to a lower risk of heart failure and atrial fibrillation, a condition that causes an irregular heart rate.

It is thought that frequent brushing reduces bacteria living between the teeth and gums, preventing it from entering the bloodstream.

Scientists in South Korea examined the connection between oral hygiene and heart problems in the study of 161,000 people aged between 40 and 79. They had a routine medical examination between 2003 and 2004.

By the time of a follow-up ten years later, around 5 percent had developed heart failure and three percent atrial fibrillation.

Brushing three or more times a day was associated with a 12 percent lower risk of heart failure and a 10 percent reduced risk of atrial fibrillation. The findings were independent of factors including age, sex, financial status, regular exercise, alcohol consumption and body mass index.

Other studies have shown that poor oral hygiene leads to bacteria in the blood, causing inflammation in the body. This increases the risk of an irregular beat and heart failure.

Thousands of Authors Publish ‘Empty’ Book to Protest AI Using their Work

Thousands of authors including Kazuo Ishiguro, Philippa Gregory and Richard Osman have published an “empty” book to protest against AI firms using their work without permission.

About 10,000 writers have contributed to Don’t Steal This Book, in which the only content is a list of their names.

Copies of the work were distributed to attenders at the London book fair on Tuesday, a week before the UK government is due to issue an assessment on the economic cost of proposed changes in copyright law.

By March 18, ministers must deliver an economic impact assessment as well as a progress update on a consultation about the legal overhaul, against a backdrop of anger among creative professionals about how their work is being used by AI firms.

The organizer of the book, Ed Newton-Rex, a composer and campaigner for protecting artists’ copyright, said the AI industry was “built on stolen work ... taken without permission or payment.”

He added: “This is not a victimless crime – generative AI competes with the people whose work it is trained on, robbing them of their livelihoods. The government must protect the UK’s creatives, and refuse to legalize the theft of creative work by AI companies.”

Other authors who have contributed their names to the book include the Slow Horses author, Mick Herron; the author Marian Keyes; the historian David Olusoga; and Malorie Blackman, the writer of Noughts and Crosses.

“It is not in any way unreasonable to expect AI companies to pay for the use of authors’ books,” said Blackman.

Images of ‌animals will feature on the next series of banknotes from the Bank of England, as the central bank shifts away from historical figures such as William Shakespeare, Winston Churchill and Jane Austen over the coming years.

"Nature is a great choice from a banknote authentication perspective and means we can showcase the UK's rich and varied wildlife on the next series of ‌banknotes," Victoria ‌Cleland, the BoE's chief cashier, said.

Bank ‌of ⁠England banknotes have ⁠featured monarchs since Queen Elizabeth first appeared on one in 1960, while Shakespeare was the first historic figure to appear in 1970.

King Charles' portrait will continue to appear on the next series of notes as well, the ⁠BoE said.

The BoE held a ‌consultation on a change ‌to the design of banknotes in July 2025, ‌inviting views from the public.

The theme of ‌nature was supported by 60% of the 44,000 responses, narrowly beating the category of "architecture and landmarks" on 56% and "notable historical figures" on 38%. Other categories included "arts, ‌culture and sport", "innovation" and "noteworthy milestones".

The new notes will feature wildlife native ⁠to ⁠the United Kingdom and will not include household pets, the BoE said. It plans to run a second consultation in the coming months asking for the public's views on specific animals to feature on the notes taken from a list created by British wildlife experts.

The BoE is not the only producer of banknotes in the United Kingdom. Notes are also produced by seven commercial banks in Scotland and Northern Ireland.

South ‌Korea's Unification Ministry said on Tuesday that passenger train services between Pyongyang and Beijing are set to resume this week, marking the end of a six-year suspension caused by the COVID-19 pandemic.

The resumption restores a critical transport link between North Korea and its primary economic ally, after ‌years of ‌strict border closures that began ‌in ⁠early 2020.

China's state ⁠railway told the Yonhap News Agency that the Pyongyang–Beijing train will begin the round-trip service on March 12, operating four times a week.

Only the last two carriages will ⁠initially carry passengers, mainly diplomats or ‌others on ‌official business, with ticket sales to the general ‌public possible if seats are ‌available, Yonhap quoted a railway official as saying.

North Korea remains closed to most foreign tourism, with limited exceptions largely for ‌Russian tour groups under restricted arrangements, according to travel agencies organizing trips ⁠to ⁠the country.

Before the pandemic, Chinese visitors made up the largest share of foreign tourists to North Korea, the agencies said.

Tour organizers said on Monday that North Korea had cancelled next month's Pyongyang Marathon for unspecified reasons. The race is one of the few events that has been open to international participants in the isolated state.
