There has been evidence that the omicron variant tends not to burrow deeply into the lungs as much as previous variants. How quickly do omicron symptoms appear? What is the duration of omicron symptoms? Although much about the omicron variant remains unknown, some experts say it could lead to long Covid, even with mild cases. The BA.5 omicron subvariant accounted for nearly 80% of new Covid cases as of Oct. 8, according to the CDC.

HONG KONG, Oct 11 (Reuters Breakingviews) - Washington's sweeping technology curbs on China today will have ripple effects across global supply chains tomorrow. But the ban may prompt Chinese chipmakers to hasten their progress in the commoditised parts of the market, embedding firms like Semiconductor Manufacturing International (0981.HK) in global supply chains. The measures mark a huge escalation in President Joe Biden's efforts to hobble Beijing's chip advances. Essentially, any company that uses American equipment will be restricted from selling relatively high-tech semiconductors or tools to Chinese firms. And because nearly every factory relies on crucial hardware and software from U.S. suppliers like Lam Research (LRCX.O) and Applied Materials (AMAT.O), the latest move potentially sets back Chinese chipmakers by years, if not decades.

HONG KONG, Oct 7 (Reuters Breakingviews) - Too much cash can be a problem sometimes, especially in South Korea. Samsung Electronics (005930.KS), meanwhile, may find that deploying its $77 billion war chest is getting trickier. The company estimates third-quarter operating profit at 10.8 trillion won ($7.7 billion), down 32% from a year earlier and below analysts’ expectations.

CNN —The experimental Alzheimer’s drug lecanemab made big news last week when the companies testing it released trial results that showed the drug met its goals, making it one of the first dementia drugs to return positive results. By some counts, lecanemab is the 16th drug that’s been developed to clear toxic amyloid plaques from the brain. Or did the companies that are testing it – Biogen and Eisai – run a smarter clinical trial that finally showcased the potential of these kinds of medications? Clinical trial results were mixed, with only one showing a small benefit to patients. He says he might change his mind if analysis of the clinical trial shows that one group of people got more of a benefit than others.

Some may be the work of Russians opposed to Putin; others show signs of military special operations. In a matter of a days this month, Ukrainian forces managed to liberate more territory than the Russian military captured and held over six months of war. For months now, sensitive sites and important facilities throughout Russia have been hit by mysterious fires and explosions, hinting at a sabotage campaign that is the hallmark of special-operations forces. Smoke and flames rise at a Russian military base in Crimea after explosions there on August 9. Stavros Atlamazoglou is a defense journalist specializing in special operations, a Hellenic Army veteran (national service with the 575th Marine Battalion and Army HQ), and a Johns Hopkins University graduate.

REUTERS/Steve Marcus - RC28BE9D5MZ7HONG KONG, Sept 20 (Reuters Breakingviews) - Seoul's foot-dragging on climate change is holding back Korea Inc. Last week the country's top conglomerate, Samsung Electronics (005930.KS), unveiled an underwhelming net-zero carbon emissions target. Most of that is probably from electricity for factories in South Korea, where renewable power is scarce. Yet President Yoon Suk-yeol's administration plans to lower its renewable-energy target for 2030, favouring nuclear power instead. The company has also joined RE100, a group of global corporations including Apple, Intel and TSMC that are committed to using 100% renewable energy across their own operations. Renewable energy will account for 21.5% of generation capacity by 2030, down from the previous target of 30.2%.

☆ Special-ops units from Down Under made their mark with US commandos in Vietnam. They may have to do it again against China.

During the Vietnam War, US troops were supported by forces from several allied countries. The role of the Australian Special Air Service Regiment (SASR) and the New Zealand Special Air Service (NZSAS) was especially notable. From 1966 to 1971, these two special-operations units deployed a small number of commandos to support conventional forces in Vietnam. Gradually, however, they shifted to a more aggressive stance and started going after high-value North Vietnamese and Viet Cong targets in ambushes and direct-action operations. Special operators from the two countries had fought with the British against Communist insurgents in Malaya and Borneo.
