IT'S A DAY of rest, and you may be in the mood for a quiet corner and a comfy chair.
We've hand-picked some of the week's best reads for you to savour.
1. How a 17-year-old solved a 40-year maths mystery

A maths paper published earlier this year left the maths world stunned after a relatively unknown author had solved a decades-old maths mystery about how functions behave, the Mizohata-Takeuchi conjecture.
(Quanta Magazine, approx 10 mins reading time)
The problem was a simplified version of the Mizohata-Takeuchi conjecture. Zhang had included it in one of his homework assignments as a warm-up, hoping to encourage students to practice advanced techniques in a deep area of math. The assignment also included an optional extension, inviting them to consider whether the proof they'd found for the simplified case could be extended to more complicated formulations of the problem. Cairo completed the problem set and took Zhang up on the invitation to keep thinking. To her, it seemed natural to follow the thread of an idea as far as it would go. 'Why would I stop?' she said.
2. Sliding into the PM's (spotlight)
Political pundits may often compare a current leader's performance to their predecessors, but sometimes through rose-tinted glasses. But why do some ex-political leaders just never… go away?
(Politico UK, approx 8 mins reading time)
While they receive £115,000 annually for life, a permanent security detail and are expected to attend Remembrance Sunday commemorations at the Cenotaph, there is no official responsibility or equivalent of a U.S.-style presidential library to promote an ex-prime minister's legacy. That can leave former leaders feeling stuck on the sidelines.
3. Treating trauma in Gaza

Palestinian journalist and author Mohammed R. Mhawish reports from Gaza, where he explores how mental health experts are treating trauma among those, young and old, who are still trapped in an active conflict.

Nour Jarada, a mental-health manager in Gaza, sees this rewiring on a daily basis. She works inside of medical tents that have no sound insulation, each one containing folding beds that separate trauma from trauma. The patients arrive on foot—some having walked for miles, many led in by family members who didn't know what else to do. 'Some don't speak,' she told me. 'They stare, sometimes scream. Most cry for hours, unblinkingly.' Children have asked Jarada if they could go back to school, as if normal were still hiding somewhere nearby.
4. Hello new world. Is anyone there?
The most-important part of starting a new website is getting people to find it on search engines. Most spend years perfecting their 'search-engine optimisation' skills. But are SEOs are a thing of the past, with new AI technology? And what now?

(New York Magazine, approx 15 mins reading time)
SEO shaped how virtually everything on the web looked and read. It's why headlines are the way they are (and why a lot of news stories get published at all). It's why online recipes read the way they read. It's why e-commerce listings are larded with text intended to catch Google's algorithmic eye. It's why so much of the web feels so uncanny, as if it's written for someone, or something, other than the people browsing it, and one of the reasons why Google itself feels so broken.
5.
Rise to the… top?
The sidekick role has been around for centuries.

The sidekick role has been around for centuries. Shylock and Launcelot, Batman and Robin, Trump and, apparently, US Speaker of the House Mike Johnson. Once a firebrand politician, Johnson is seen firmly on the White House's side.
(Time, approx 15 mins reading time)
Expectations for Johnson in Washington were low.But he has defied them. Since Trump's Inauguration, Johnson has shepherded a series of wins for the White House: thwarting a vote blocking Trump's sweeping tariffs, passing the Laken Riley Act expediting the deportation of arrested migrants, averting a government shutdown, and delivering pro-crypto legislation that blesses certain digital assets tied to the U.S. dollar.
6. Europe and its off-the-rail trains
We've heard plenty about the Metrolink, DART expansion, the introducing of new Luas lines and even a dreamed of rail connection to the UK. One thing is for sure, it's costly and timely. No more is that evident than at Europe's cross-border rail line.
(The Guardian, approx 8 mins reading time)
Leaving aside the nonexistent connectivity, the obstacles facing the long-distance European rail traveller will have become apparent long before they actually get on a train. Planning a trip and buying tickets (as well resolving problems if things go wrong) are daunting challenges in themselves. Seasoned travellers recommend Deutsche Bahn's website as the best and most comprehensive planning tool, but few novices would describe even that as user-friendly.
…AND A CLASSIC FROM THE ARCHIVES…

Even once he became an adult, he would refuse to believe girlfriends who reassured him that his weight was fine. 'I'm very self-critical and I use that to motivate myself.

Israeli bombardment of Gaza kills at least 89, as five more die of starvation

The latest round of indirect talks in Qatar ended in deadlock late last month, with Israel and Hamas trading blame over the lack of progress on a US proposal for a 60-day truce and hostage release deal. Israel has since said it will launch a new offensive and seize control of Gaza City, which it captured shortly after the war's outbreak in October 2023 before pulling out. Israeli prime minister Benjamin Netanyahu's plan to expand military control over Gaza, expected to be launched in October, has increased a global outcry over the widespread devastation, displacement and hunger afflicting Gaza's 2.2 million people. It has also stirred criticism in Israel, with the military chief of staff warning it could endanger surviving hostages and prove a death trap for Israeli soldiers. It has also raised fears of further displacement and hardship among the estimated one million Palestinians in the Gaza City region. Famine is unfolding before our eyes. Urgent action is needed now to halt and reverse starvation Foreign ministers of 24 countries, including Ireland, said yesterday the humanitarian crisis in Gaza had reached 'unimaginable levels' and urged Israel to allow unrestricted aid into the enclave. 'Famine is unfolding before our eyes. Urgent action is needed now to halt and reverse starvation,' the foreign ministers said in a joint statement. 'We call on the government of Israel to provide authorisation for all international NGO (non-governmental organisations) aid shipments and to unblock essential humanitarian actors from operating. 'All crossings and routes must be used to allow a flood of aid into Gaza, including food, nutrition supplies, shelter, fuel, clean water, medicine and medical equipment.' The statement was signed by the foreign ministers of Australia, Belgium, Canada, Cyprus, Denmark, Estonia, Finland, France, Greece, Iceland, Ireland, Japan, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and the UK. Israel denies responsibility for hunger in Gaza, accusing Hamas of stealing aid. It says it has taken steps to increase deliveries, including pausing fighting in some areas and announcing protected routes for aid convoys. A Palestinian official with knowledge of the mediated ceasefire talks said Hamas was prepared to return to the negotiating table, and the leaders who were visiting Cairo yesterday would reaffirm that stance. ADVERTISEMENT 'Hamas believes negotiation is the only way to end the war and is open to discuss any ideas that would secure an end to the war,' the official, who asked not to be named due to the sensitivity of the matter, told Reuters. Egypt's state-affiliated Al Qahera News television said the Hamas delegates have arrived in Egypt 'for consultations on ceasefire talks'. However, the gaps between the sides appear to remain wide on key issues, including the extent of any Israeli military withdrawal and demands for Hamas to disarm. A Hamas official told Reuters yesterday the Islamist movement was ready to relinquish Gaza governance on behalf of a non-partisan committee, but it would not relinquish its arms before a Palestinian state is established. Mr Netanyahu, whose far-right ultranationalist coalition allies want an outright Israeli takeover of all of Gaza, has vowed the war will not end until Hamas is eradicated. Yeterday, Gaza's health ministry said that 89 Palestinians had been killed by Israeli fire in the past 24 hours. Witnesses and medics said Israeli bombardments overnight killed seven people in two houses in Gaza City's Zeitoun suburb and another four in an apartment building in the city centre. In the south of Gaza, five people, including a couple and their child, were killed by an Israeli airstrike on a house in the city of Khan Younis and four others by a strike on a tent encampment in nearby coastal Mawasi, medics said. The Israeli military said it was looking into the reports of the latest bombardments and that its forces take precautions to mitigate civilian harm. Separately, it said its forces had killed dozens of militants in north Gaza over the past month and destroyed more tunnels used by militants in the area. Five more people, including two children, have died of starvation and malnutrition in Gaza in the past 24 hours, the territory's health ministry said.

Letters: The camera and the pen bear witness to genocidal regimes

During this summer of 2025, I read a piece shared on Facebook in which the French foreign minister urged Israel to allow foreign press into the Gaza Strip. The words 'Bear witness' stare out at me from my screen. We have all seen images and docu­mentary evidence of Gaza and the horrors that are being inflicted on the Palestinian people. I have had fear and concern about sharing images and reports, not because of the shock and dismay this brings into our comfortable homes (I believe we should be awake and informed), but because I worried that sharing these images and reports might mean that reporters are targeted – which, by all accounts and most recent attacks, suggest they are. If the answer to Medb Ruane's question was 'no', then reporters and photographers from outside would have the freedom to do their job in safety. I believe the answer to her question is most definitely 'yes', because exposure through the power of the lens and pen is something that a genocidal regime would have obvious fears about. Margaret O'Brien, Nenagh, Co Tipperary US needs to take control of its own future and stop playing the short game Looking at what is happening in the US isn't politics as we used to know it. It's more like a card game in which the players are spending money they don't have, knowing they'll be gone before the bill arrives. Leaders grab what they can today and leave the mess for someone else tomorrow. Take the latest in Washington DC. Donald Trump declares crime is out of control, sending federal agents and National Guard troops to 'stop violent crime' and pushing to charge teen­agers as young as 14 as adults ('Donald Trump claims crime in Washington DC is out of control. Here's what the data shows', Irish Independent, August 12). Yet official data show juvenile arrests in DC are down nearly 20pc this year, violent crime is falling and homicide rates are at multi-decade lows nationally. ADVERTISEMENT The 'out of control' narrative is largely a political performance that obscures the reality, but that doesn't mean serious problems don't exist. Bit by bit, the US government is being hollowed out, markets are left to run wild and ordinary people are left with fewer tools to deal with big problems like climate change and disappearing jobs. People end up tired, distracted and too busy to look ahead. If nothing changes, America will split in two. One side will be wealthy and mobile, taking advantage of new technology and global markets, while the other will be stuck with climate disasters, fewer jobs and crumbling services. The gap will grow until each side might as well be living in a different country. Ireland has learnt the hard way that if you don't take control of your own future, someone else will – and they won't do it for your benefit. America has to decide soon whether to keep playing the short game or start building something that lasts. Enda Cullen, Tullysaran Road, Armagh Fair play, Charlie Weston, for highlighting forever rising cost of electricity Charlie Weston is doing us all some service with his persistence in highlighting the excessive cost of electricity and the dreadful misery being inflicted on many households as a consequence ('Fears of arrears crisis as record number of families are three months or more behind on energy bills', August 12) But it seems that no one in the Government is listening, and certainly no one seems to want to discuss the elephant in the room – the negative impact on charges that the decision to transform this natural monopoly into an artificial, competitive market has had. As pointed out before, when electricity was generated and supplied by a single semi-state entity, the ESB, Ireland enjoyed the lowest electricity charges in Europe. The reason is very simple: in the privatised scenario, householders are not only having to pay the cost of generation and supply as they did under the semi-state ESB, but on top of that they now must fund the profit margin, the multiple CEOs and duplicated management structures and, by far the most outrageous, the cost of all the advertising we see every night on our TVs as the various entities now sitting between the customer and access to electricity compete for our attention at our expense. Surely with such a vital social good, such a waste is indefensible. The failure to properly debate the decision to outsource this vital service at the time meant that citizens were essentially in the dark. Jim O'Sullivan, Rathedmond False promises of more gardaí on beat when there aren't enough in the force My motorbike was stolen last evening outside my work premises in Artane. Many of us have experienced that dreaded feeling of walking out and discovering that your car or motorbike has been taken and, most likely, burnt out or otherwise destroyed. The gardaí were brilliant and did everything in their power to get it back, but, unfortunately, when dealing with stolen bikes their hands are tied. The political lip service is to get more gardaí on the streets while knowing there aren't enough officers to patrol the country as a whole. I can understand why young people don't want to join the force when every action is scrutinised and videoed. On a recent trip to Cardiff on my motorbike, I noted that it is a very safe city to walk around as they have employed city wardens, akin to the security people on the Dart, who wear hi-vis jackets and patrol the city centre in small groups during the day and on Friday and Saturday evenings, helping tourists and dealing with anti-social behaviour. Basically, they are a step down from the gardaí, but bring a feeling of security. Aidan Hampson, Artane, Dublin Why am I always 12th in the telephone queue when calling our state services? It is amusing that when you ring any of our state services, the first thing you hear is that 'we are experiencing an unusually high volume of calls'. I phoned a public body at 1.30pm on Monday and was told I was 12th in the queue, so I rang off. I rang again at 4pm to again be told I was still in 12th place. That 11th caller must be some yapper.

Israel intensifies bombing of Gaza, killing 89 Palestinians in 24 hours

Israel has stepped up bombing Gaza, killing at least 89 Palestinians in 24 hours, including at least 15 people queueing for food, despite global outcry over the deaths of six journalists% in the territory the previous day. Gaza's civil defence agency said Israeli airstrikes on Gaza City had intensified in the three days after Benjamin Netanyahu's security cabinet approved plans to expand the war in the territory. Five more people, including two children, were reported to have died of starvation, as the foreign ministers of 24 countries including Britain, Australia, France, Spain and Japan warned that 'humanitarian suffering in Gaza has reached unimaginable levels'. The ministers and the EU foreign policy chief, Kaja Kallas, called on the government of Israel to let in aid shipments immediately and allow essential humanitarian actors to operate in Gaza. 'Urgent action is needed now to halt and reverse starvation,' they said. More than 15 people were killed while waiting for food distribution at the Zikim crossing in northern Gaza, said Fares Awad, head of the ambulance services in northern Gaza. In the south of the territory, five people, including a couple and their child, were killed by an Israeli airstrike on a house in the city of Khan Younis and four by a strike on a tent encampment in nearby Mawasi, medics said. The civil defence agency spokesperson Mahmud Bassal said the residential neighbourhoods of Zeitoun and Sabra had been hit 'with very heavy airstrikes targeting civilian homes, possibly including high-rise buildings'. The bombardment was described by residents as the heaviest in weeks. 'It sounded like the war was restarting,' Amr Salah, 25, told Reuters. 'Tanks fired shells at houses, and several houses were hit, and the planes carried out what we call fire rings, whereby several missiles landed on some roads in eastern Gaza.' ''There are martyrs under the rubble that no one can reach because the shelling hasn't stopped,' said Majed al-Hosary, a resident in Zeitoun. Eleven bodies were recovered from the rubble of previous Israeli attacks, the ministry said on Telegram, including several casualties caused by strikes on Gaza City. The Israeli military said it was looking into the reports and that its forces took precautions to mitigate civilian harm. Separately, it said that its forces had killed dozens of militants in north Gaza over the past month and destroyed more tunnels used by militants in the area.

Picture: Jehad Alshrafi/AP There was no sign on the ground of forces moving deeper into Gaza City as part of the newly approved Israeli offensive, which was expected to begin in the coming weeks. The most recent famine-related deaths brought the total number of hunger-related deaths recorded since October 7 2023 to 227, including 103 children, according to Gaza's health ministry. Nasser Medical Complex confirmed a six-year-old boy had died of hunger-related illness in the southern city of Khan Younis, while doctors said a 30-year-old man had died of malnutrition. Israel has faced mounting criticism over the 22-month-long war with Hamas, with UN-backed experts warning of widespread famine unfolding in besieged Gaza. Israel has imposed a blockade and restrictions on aid entering the territory, but in his press conference on Sunday Netanyahu said it was 'completely false' that his government was pursuing a 'starvation policy'. He acknowledged hunger, and problems with the food distribution system run by the US and Israeli-backed Gaza Humanitarian Foundation, but accused the media of 'lies' about the scale of the problem. Twenty-two months into the conflict, Israel's war on Gaza has killed a total of 61,599 Palestinians and injured 154,088 since 7 October 2023, according to Gaza's health ministry. An outpouring of condemnation has followed the death of the prominent Al Jazeera journalist Anas al-Sharif, killed along with four colleagues in an Israeli airstrike on Sunday. The Hind Rajab Foundation (HRF) and the Palestinian Center for Human Rights said they would file a joint complaint to the international criminal court over their killings. The Israel Defense Forces admitted carrying out the attack, claiming Sharif was the leader of a Hamas cell responsible for rocket attacks against Israel – an allegation that Al Jazeera and Sharif had previously dismissed as baseless. HRF's investigation traces the chain of command from Netanyahu to senior Israeli army figures, including air force and intelligence commanders. The UN secretary general, António Guterres, condemned their deaths and his spokesperson called for an independent investigation. The head of the UN agency for Palestinian refugees, Philippe Lazzarini, said in a post on X: 'The Israeli Army continues to silence voices reporting atrocities from Gaza.' 'I am horrified by the killing of another 5 journalists in Gaza City. Since the war began, more than 200 Palestinian journalists have been reported killed in total impunity.' — The Guardian
