High levels of lead detected in authenticated locks of Ludwig van Beethoven’s hair suggest that the composer had lead poisoning, according to new research.

In addition to hearing loss, the famed classical composer had recurring gastrointestinal complaints throughout his life, experienced two attacks of jaundice and faced severe liver disease, CNN reported.

It is believed that Beethoven died from liver and kidney disease at age 56.

The composer expressed his wish that his ailments be studied and shared so “as far as possible at least the world will be reconciled to me after my death.”

An international team of researchers set out nearly a decade ago to partially fulfill Beethoven’s wish by studying locks of his hair, CNN said. Using DNA analysis, the team determined which ones truly belonged to the composer and which were fraudulent, and sequenced Beethoven’s genome by analyzing his authenticated locks.

The findings, published in a March 2023 report, revealed that Beethoven had significant genetic risk factors for liver disease and a hepatitis B infection before his death. But the results didn’t provide any insights into the underlying causes of his deafness, which began in his 20s, or his gastrointestinal issues.

Beethoven’s genome was made publicly available, inviting researchers around the world to investigate lingering questions about Beethoven’s health.

Meanwhile, scientists continue to figuratively go over the authenticated locks of Beethoven’s hair with a fine-tooth comb, teasing out surprising insights.

In addition to high concentrations of lead, the latest findings showed arsenic and mercury that remain trapped in the composer’s strands nearly 200 years after his death, according to a new letter published Monday in the journal Clinical Chemistry. And the insights could provide new windows not only into understanding Beethoven’s chronic health ailments, but the complicated nuances of his life as a composer, CNN said.



Dutch 'Fish Doorbell' Turns Into Unlikely Online Hit Combining Slow TV, Ecology

The central Dutch city of Utrecht has installed a “fish doorbell” on a river lock that lets viewers of an online livestream alert authorities to fish being held up as they make their springtime migration to shallow spawning grounds.
The idea is simple: An underwater camera at Utrecht's Weerdsluis lock sends live footage to a website. When somebody watching the site sees a fish, they can click a button that sends a screenshot to organizers. When they see enough fish, they alert a water worker who opens the lock to let the fish swim through, The Associated Press reported.
Now in its fifth year, the site has attracted millions of viewers from around the world with its quirky mix of slow TV and ecological activism.
Much of the time, the screen is just a murky green with occasional bubbles, but sometimes a fish swims past. As the water warms up, more fish show up.
Without the help, native freshwater fish like bream, pike and bass can become backed up behind the lock and form easy prey for predators in the spring, when the lock is rarely opened for passing boats.
The bell is the brainchild of ecologist and concept developer Mark van Heukelum. He's been happily surprised at the response, with millions of people from around the world tuning in over the years.
“I guess the combination of a good cause, a beautiful story and just a simple idea generates all this attention," he said.
Anna Nijs, an ecologist with Utrecht municipality, was also amazed at the popularity of the concept around the world.
“We get a lot of fan mail from people who think it’s slow TV and they find it relaxing," said Nijs. Besides, “they appreciate that they can actually do something to help.”
