US midterms: Polls show Democrats ahead in battle for Congress

Democrats lead Republicans in national polling ahead of Tuesday's United States midterm elections, with new surveys showing the party gaining ground in several closely contested Senate races as voters express dissatisfaction with President Donald Trump's handling of the economy. With all 435 House of Representatives seats and 35 Senate seats on the ballot, the elections will determine whether Republicans retain control of Congress for the remaining two years of Trump's second term. A RealClearPolling average of surveys conducted through October 30 shows Democrats leading Republicans 52% to 43.1% on the generic congressional ballot, an 8.9-percentage-point advantage. An NBC News survey conducted October 28-30 found Democrats ahead 52% to 45%, while an Emerson College poll conducted October 24-26 put the gap at 10 points. The generic ballot measures nationwide preferences for congressional candidates rather than support in individual districts, meaning a nati...

World's largest iceberg breaks free, heads toward Southern Ocean

The world's largest iceberg is on the move for the first time in more than three decades, scientists said on Friday. At almost 4,000 square km (1,500 square miles), the Antarctic iceberg called A23a is roughly three times the size of New York City. Since calving off West Antarctica's Filchner-Ronne Ice Shelf in 1986, the iceberg — which once hosted a Soviet research station — has largely been stranded after its base became stuck on the floor of the Weddell Sea. Not anymore. Recent satellite images reveal that the berg, weighing nearly a trillion metric tonnes, is now drifting quickly past the northern tip of the Antarctic Peninsula, aided by strong winds and currents. It's rare to see an iceberg of this size on the move, said British Antarctic Survey glaciologist Oliver Marsh, so scientists will be watching its trajectory closely. As it gains steam, the colossal berg will likely be launched into the Antarctic Circumpolar Current. This will funnel it toward the Southern Ocean on a path known as "iceberg alley" where others of its kind can be found bobbing in dark waters.

"Over time it's probably just thinned slightly and got that little bit of extra buoyancy that's allowed it to lift off the ocean floor and get pushed by ocean currents," said Marsh. A23a is also among the world's oldest icebergs. It’s possible A23a could again become grounded at South Georgia island. That would pose a problem for Antarctica's wildlife. Millions of seals, penguins, and seabirds breed on the island and forage in the surrounding waters. Behemoth A23a could cut off such access. In 2020, another giant iceberg, A68, stirred fears that it would collide with South Georgia, crushing marine life on the sea floor and cutting off food access. Such a catastrophe was ultimately averted when the iceberg broke up into smaller chunks — a possible end game for A23a as well. But "an iceberg of this scale has the potential to survive for quite a long time in the Southern Ocean, even though it's much warmer, and it could make its way farther north up toward South Africa where it can disrupt shipping," said Marsh.

At least 32 miners dead after bridge fails at cobalt site in southeast DR Congo

A bridge collapsed at a cobalt mine in southeast Democratic Republic of Congo killing at least 32 wildcat miners, a regional government official said Sunday. The bridge came down Saturday onto a flooded zone at the mine in Lualaba province, Roy Kaumba Mayonde, the provincial interior minister, told reporters. He said 32 bodies had been recovered and more were being searched for. The DRC produces more than 70 percent of the world supply of cobalt, which is essential for batteries used in electric cars, many laptop computers and mobile phones. More than 200,000 people are estimated to be working in giant illegal cobalt mines in the giant central African country. Local authorities said the bridge collapsed at the Kalando mine, about 42 kilometres (26 miles) southeast of the Lualaba provincial capital, Kolwezi. "Despite a formal ban on access to the site because of the heavy rain and the risk of a landslide, wildcat miners forced their way into the quarry," said Mayonde. He said ...

Arab countries, Pakistan likely to observe Eid on same day

The International Astronomy Centre confirmed on Wednesday that the crescent moon of Shawwal will be impossible to sight on Saturday, March 29, across all regions of the Arab and Islamic world. This is due to the moon setting before the sun, with the conjunction occurring after sunset. As a result, observing the crescent moon, whether by the naked eye, telescopes, or other means, will be unfeasible on March 29. For countries requiring an actual sighting to mark the start of Shawwal, Ramadan will likely extend to 30 days, with Eid Al Fitr falling on Monday, March 31. However, in some regions where the conjunction occurs before sunset, allowing the moon to set after sunset, some countries may choose to declare Eid on Sunday, March 30, following traditional moon-sighting practices. Notably, a partial solar eclipse will be visible at noon on Saturday in parts of the western Arab world, including Mauritania, Morocco, Algeria, and Tunisia. This event serves as definitive proof that the cresce...

Hajj scam alert: How to verify licensed service providers

As millions of Muslims prepare for their Hajj pilgrimage, the Saudi Ministry of Hajj and Umrah (MOHU) has issued a critical warning against fraudulent Hajj campaigns, urging pilgrims to use only licensed service providers for a smooth and safe experience. To help ensure authenticity, the ministry recommends pilgrims use their official website, www.haj.gov.sa, to verify licensed Hajj operators. This applies to domestic pilgrims, including Saudi citizens and residents, who can access a simple online tool to check accredited companies. For UAE nationals, the General Authority of Islamic Affairs and Endowments (Awqaf) maintains a list of approved operators on awqaf.gov.ae. International pilgrims have two main options to ensure their chosen provider is licensed. Those from eligible countries can use the Nusuk platform at hajj.nusuk.sa, an online service that facilitates Hajj bookings with accredited providers. A full list of eligible countries is available on the platform’s website. For tho...
