Scientists described the collapse of the giant radio telescope in Puerto Rico this week as a "huge loss" after more than half a century of scientific discoveries in which it played a key role.
The US National Science Foundation had already said it would close the radio telescope after an auxiliary cable snapped in August, causing a 30-metre gash on the 305m-wide dish and damaging the receiver platform that hung above it, followed by a a main cable breaking in early November.
On Tuesday, the telescope's 900-tonne receiver platform and the Gregorian dome — a structure as tall as a four-story building that houses secondary reflectors — fell onto the northern portion of the vast reflector dish more than 100 metres below.
“It sounded like a rumble. I knew exactly what it was,” said Jonathan Friedman, who worked for 26 years as a senior research associate at the observatory and still lives near it.
“I was screaming. Personally, I was out of control," Mr Friedman told the Associated Press. "I don't have words to express it. It's a very deep, terrible feeling.”
Mr Friedman ran up a small hill near his home and confirmed his suspicions: a cloud of dust hung in the air where the structure once stood, demolishing hopes held by some scientists that the telescope could somehow be repaired.
The collapse was not a surprise because many of the wires in the thick cables holding the structure snapped over the weekend, Angel Vazquez, the telescope’s director of operations, said.
“It was a snowball effect,” he said. “There was no way to stop it. It was too much for the old girl to take.”
He said that it was extremely difficult to say whether anything could have been done to prevent the damage that occurred after the first cable snapped in August.
“The maintenance was kept up as best as we could,” he said. The National Science Foundation "did the best that they could with what they have”.
However, observatory director Francisco Cordova, said that while the NSF decided it was too risky to repair the damaged cables before Tuesday's collapse, he believes there had been options, such as relieving tension in certain cables or using helicopters to help redistribute weight.
Meanwhile, installing a new telescope would cost up to $350 million, money the NSF does not have, Mr Vazquez said, adding it would have to come from U.S. Congress.
“It's a huge loss,” said Carmen Pantoja, an astronomer and professor at the University of Puerto Rico who used the telescope for her doctorate. “It was a chapter of my life.”
Scientists worldwide had been petitioning US officials and others to reverse the NSF's decision to close the observatory. The NSF said at the time that it intended to eventually reopen the visitor centre and restore operations at the observatory’s remaining assets, including its two Lidar facilities used for upper atmospheric and ionospheric research, including analysing cloud cover and precipitation data. The Lidar facilities are still operational, along with a 12-metre telescope and a photometer used to study photons in the atmosphere, Mr Vazquez said.
“We are saddened by this situation but thankful that no one was hurt,” NSF Director Sethuraman Panchanathan said in a statement. “When engineers advised NSF that the structure was unstable and presented a danger to work teams and Arecibo staff, we took their warnings seriously.”
The telescope was built in the 1960s with money from the Defence Department amid a push to develop anti-ballistic missile defences. It had endured hurricanes, tropical humidity and a recent string of earthquakes in its 57 years of operation.
The telescope has been used to track asteroids on a path to Earth, conduct research that led to a Nobel Prize and determine if a planet is potentially habitable. It also served as a training ground for graduate students and drew about 90,000 visitors a year.
“I am one of those students who visited it when young and got inspired,” said Abel Mendez, a physics and astrobiology professor at the University of Puerto Rico at Arecibo who has used the telescope for research. “The world without the observatory loses, but Puerto Rico loses even more.”
He last used the telescope on August 6, just days before a socket holding the auxiliary cable that snapped failed in what experts believe could be a manufacturing error. The NSF, which owns the observatory that is managed by the University of Central Florida, said crews who evaluated the structure after the first incident determined that the remaining cables could handle the additional weight.
But on November 6, another cable broke.
Scientists had used the telescope to study pulsars to detect gravitational waves as well as search for neutral hydrogen, which can reveal how certain cosmic structures are formed. About 250 scientists worldwide had been using the observatory when it closed in August, including Mr Mendez, who was studying stars to detect habitable planets.
“I'm trying to recover,” he said. “I am still very much affected.”

Three ways to limit your social media use
Clinical psychologist, Dr Saliha Afridi at The Lighthouse Arabia suggests three easy things you can do every day to cut back on the time you spend online.
1. Put the social media app in a folder on the second or third screen of your phone so it has to remain a conscious decision to open, rather than something your fingers gravitate towards without consideration.
2. Schedule a time to use social media instead of consistently throughout the day. I recommend setting aside certain times of the day or week when you upload pictures or share information.
3. Take a mental snapshot rather than a photo on your phone. Instead of sharing it with your social world, try to absorb the moment, connect with your feeling, experience the moment with all five of your senses. You will have a memory of that moment more vividly and for far longer than if you take a picture of it.

Subj: Accelerating in the Middle East
Five years ago, Uber launched in the Middle East. It was the start of an incredible journey, with millions of riders and drivers finding new ways to move and work in a dynamic region that’s become so important to Uber. Now Pakistan is one of our fastest-growing markets in the world, women are driving with Uber across Saudi Arabia, and we chose Cairo to launch our first Uber Bus product late last year.
Today we are taking the next step in this journey—well, it’s more like a leap, and a big one: in a few minutes, we’ll announce that we’ve agreed to acquire Careem. Importantly, we intend to operate Careem independently, under the leadership of co-founder and current CEO Mudassir Sheikha. I’ve gotten to know both co-founders, Mudassir and Magnus Olsson, and what they have built is truly extraordinary. They are first-class entrepreneurs who share our platform vision and, like us, have launched a wide range of products—from digital payments to food delivery—to serve consumers.
I expect many of you will ask how we arrived at this structure, meaning allowing Careem to maintain an independent brand and operate separately. After careful consideration, we decided that this framework has the advantage of letting us build new products and try new ideas across not one, but two, strong brands, with strong operators within each. Over time, by integrating parts of our networks, we can operate more efficiently, achieve even lower wait times, expand new products like high-capacity vehicles and payments, and quicken the already remarkable pace of innovation in the region.
This acquisition is subject to regulatory approval in various countries, which we don’t expect before Q1 2020. Until then, nothing changes. And since both companies will continue to largely operate separately after the acquisition, very little will change in either teams’ day-to-day operations post-close. Today’s news is a testament to the incredible business our team has worked so hard to build.
It’s a great day for the Middle East, for the region’s thriving tech sector, for Careem, and for Uber.
Uber on,
Dara

Conflict, drought, famine
Estimates of the number of deaths caused by the famine range from 400,000 to 1 million, according to a document prepared for the UK House of Lords in 2024.
It has been claimed that the policies of the Ethiopian government, which took control after deposing Emperor Haile Selassie in a military-led revolution in 1974, contributed to the scale of the famine.
Dr Miriam Bradley, senior lecturer in humanitarian studies at the University of Manchester, has argued that, by the early 1980s, “several government policies combined to cause, rather than prevent, a famine which lasted from 1983 to 1985. Mengistu’s government imposed Stalinist-model agricultural policies involving forced collectivisation and villagisation [relocation of communities into planned villages].
The West became aware of the catastrophe through a series of BBC News reports by journalist Michael Buerk in October 1984 describing a “biblical famine” and containing graphic images of thousands of people, including children, facing starvation.
Band Aid
Bob Geldof, singer with the Irish rock group The Boomtown Rats, formed Band Aid in response to the horrific images shown in the news broadcasts.
With Midge Ure of the band Ultravox, he wrote the hit charity single Do They Know it’s Christmas in December 1984, featuring a string of high-profile musicians.
Following the single’s success, the idea to stage a rock concert evolved.
Live Aid was a series of simultaneous concerts that took place at Wembley Stadium in London, John F Kennedy Stadium in Philadelphia, the US, and at various other venues across the world.
The combined event was broadcast to an estimated worldwide audience of 1.5 billion.
