A recent study has found that sperm deteriorates over time as it remains in the body, leading researchers to suggest that men who ejaculate more frequently may have better sperm quality.The study, which combined 115 human studies involving nearly 55,000 men and 56 studies on non-human species, found that the longer men went without sex, the more their sperm showed signs of DNA damage and oxidative stress, and the more tests rated the sperm as less viable and poorer swimmers.The World Health Organization (WHO) recommends men abstain from ejaculating for two to seven days before giving sperm for fertility tests or IVF, but the guidelines were designed to obtain the highest sperm count rather than prioritizing the best quality sperm.Dr. Krish Sanghvi, lead author of the study, said: "In men, the negative effects we found on sperm DNA damage and oxidative damage were large-ish, so we are confident that this is a biologically meaningful and important effect."The study's findings suggest that clinicians and couples should reconsider whether long abstinence is always good, as abstinence leads to deterioration in sperm quality.For couples trying to conceive naturally, a balance between quantity and quality needs to be struck, with abstaining for too long or too little potentially affecting sperm quality and quantity.Experts say that for assisted reproductive technology (ART) treatments, it's having the freshest, most healthy sperm that is probably more important, and that the two to seven days abstinence rule may not be as crucial when IVF treatment is taking place.

According to a report by IQAir, a Swiss air quality monitoring firm, Pakistan was the world's smoggiest country in 2025 with concentrations of hazardous fine particles known as PM2.5 up to 13 times higher than the World Health Organization's (WHO's) recommended level.The report, which sourced data from 9,446 cities in 143 countries, regions and territories, found that only 13 countries and territories managed to keep their average fine particulate levels below the WHO guideline, an increase from seven in 2024.Pakistan's PM2.5 level was 67.3 microgrammes per cubic metre, significantly exceeding the WHO standard of 5 microgrammes per cubic metre. In comparison, Pakistan's average PM2.5 concentration in 2024 was 73.7 microgrammes.Prolonged exposure to PM2.5 has been linked to higher likelihoods of neurodegenerative conditions, including dementia, Parkinson's disease and Alzheimer's disease.Bangladesh and Tajikistan ranked second and third on IQAir's list of the most polluted countries while Chad, statistically the smoggiest country in 2024, was in fourth place in 2025.The report also noted that Loni, a city in northern India, was identified as the world's most polluted city in 2025 with average PM2.5 levels of 112.5 microgrammes per cubic metre.Globally, only 14 percent of cities met the WHO air quality standard in 2025, down from 17 percent a year earlier. The report highlighted that wildfires, driven by climate change, were a key factor behind worsening global air quality in 2025 as record levels of biomass burning in Europe and Canada released about 1,380 megatonnes of carbon.

Israeli Finance Minister Bezalel Smotrich has called for the annexation of southern Lebanon, stating that the region's bombardment "needs to end with a different reality entirely", including a "change of Israel's borders".In a radio interview, Smotrich suggested that the new Israeli border should be the Litani River, a critical waterway in southern Lebanon. This comes as Israel continues its military operations in the area, targeting residential buildings and civilian infrastructure.The United Nations has warned that Israeli attacks may amount to war crimes, with over 1,039 people killed, including 118 children, and 2,876 wounded in Lebanon since early March. The conflict has also led to the displacement of over 1.2 million people, with many fleeing under threat of attack.The Israeli military has issued forced displacement orders for southern Lebanon and the southern suburbs of Beirut, prompting hundreds of thousands to flee. The World Health Organization has recorded at least 64 attacks on healthcare facilities, resulting in 51 deaths and 91 injuries.

Pakistan and Afghanistan have agreed to a temporary ceasefire during the Muslim holiday of Eid al-Fitr, which begins on Thursday and lasts until Tuesday. The decision was made amid weeks of deadly violence between the neighboring countries.Pakistani Information Minister Attaullah Tarar announced that the ceasefire was requested by Saudi Arabia, Qatar, and Turkey. He stated that Pakistan is offering this gesture in good faith and in keeping with Islamic norms.However, Tarar also warned that if there are any cross-border attacks, drone attacks, or terrorist incidents inside Pakistan, military operations will immediately resume with renewed intensity.The Taliban government in Afghanistan also confirmed that it would temporarily suspend military operations against Pakistan.The ceasefire comes after Afghanistan accused Pakistan of killing hundreds of people in an air strike on a drug rehabilitation center in Kabul. Pakistan has strongly rejected these claims, stating that it only targets terrorist infrastructure and military locations.The United Nations reported 143 deaths in the incident at the Omar Addiction Treatment Hospital, a 2,000-bed facility. The conflict has led to repeated cross-border clashes and air strikes inside Afghanistan, despite international calls for a ceasefire and concerns about a widening displacement crisis.The World Health Organization (WHO) chief, Tedros Adhanom Ghebreyesus, urged all parties to de-escalate and prioritize peace and health, noting that at least six health facilities in Afghanistan have been affected by the violence since late February.The Qatari Ministry of Foreign Affairs welcomed the temporary truce as a positive gesture that contributes to de-escalation and promotes calm between the two sides. They hope the pause in fighting will pave the way for a return to a sustainable ceasefire agreement that spares civilian lives and achieves security and stability.
