SINGAPORE (The Straits Times/ANN): The Eta Aquarids meteor shower, born from the dusty trail of a comet, is set to make its annual appearance in Singapore's skies next week, with peak activity expected during the early hours of May 6 and 7.
Skygazers might catch a fleeting glimpse of this cosmic event if the weather holds and light pollution does not stand in the way.
On May 2, the Observatory at Science Centre Singapore said a meteor shower takes place when the Earth passes through a stream of debris left behind by sources such as comets, asteroids or other planets.
These tiny fragments, often no larger than grains of sand, burn up as they collide with Earth's atmosphere, creating the fast-moving streaks of light called meteors or 'shooting stars'.
The Eta Aquarids is an annual meteor shower linked to Comet 1P/Halley, also known as Halley's Comet.
According to US space agency Nasa, Halley's Comet is known as the most famous comet due to its historic significance.
Until the 18th century, comets were thought to make only a single journey through Earth's solar system. That changed in 1705, when English astronomer Edmond Halley used Sir Isaac Newton's laws of gravity and motion to study comet paths.
He noticed similarities in the orbits of bright comets seen in 1531, 1607 and 1682, and proposed that they were, in fact, the same comet returning over time.
He predicted it would come back again in 1758 and it did. It became the first known 'periodic' comet and was later named in his honour.
Meteors in the Eta Aquarids meteor shower are fast, zipping into the Earth's atmosphere at around 65 kilometres per second. Some leave glowing 'trains' that can linger for minutes.
When the phenomenon peaks, observers may see up to 50 meteors per hour radiating from the direction of the constellation Aquarius, near the star Eta Aquarii.
The shower is active from April 20 to May 21, but visibility will be highest after 3am on May 6 and 7, when the radiant point is higher in the sky and the bright gibbous Moon has set.
For the best chance of spotting a meteor or two, the Observatory suggests heading to open, darker locations such as beaches, parks or reservoirs.
Those looking to spot meteors in those areas should first allow their eyes 20 to 30 minutes to adjust to the dark. No telescope or binoculars are needed – just patience, clear skies and a little luck.
This cosmic event follows the recent Lyrid meteor shower in April, which many in Singapore missed due to cloudy skies. If the heavens cooperate this time, the Eta Aquarids could offer a brief but beautiful reminder of the wonders beyond the city lights. - The Straits Times/ANN

Implants could help treat eye condition that causes vision loss, according to new innovation
SINGAPORE (The Straits Times/ANN): Instead of receiving uncomfortable eye injections around once a month for a disease that can lead to blindness, patients may soon have an easier alternative. A new innovation will allow them to be treated for neovascular age-related macular degeneration (nAMD) twice a year via an implant the size of a rice grain. Swiss healthcare firm Roche, which developed the treatment, is now conducting a study of the implant involving more than 400 participants in 16 countries, including Singapore – the only country in South-east Asia in the study and one of only three Asian countries. The study, which ends in December 2026, looks at the efficacy and safety of refilling the implant every nine months, compared with every six months. The implant has already received approval from the US Food and Drug Administration. Treating nAMD currently requires injections into the eye as often as once a month. Studies have noted that patients' discomfort with the treatment can lead to undertreatment of the disease. It affects the part of the eye that provides the sharp vision needed for activities such as reading and driving, and can result in rapid and severe vision loss if left untreated. The vision loss occurs when new and abnormal blood vessels grow uncontrolled under the macula – the part of the retina responsible for sharp central vision – causing swelling, bleeding and fibrosis. The condition, also known as 'wet' AMD because these new blood vessels leak fluid into the retina, is one of the leading causes of blindness in Singapore, affecting more than 125,000 people aged 40 or older. This number is expected to increase to almost 200,000 by 2040, according to a study published in Annals, the official journal of the Academy of Medicine, Singapore, in 2018. Roche's innovation to treat nAMD is a refillable eye implant that continuously delivers a customised formulation of ranibizumab – a drug used to treat a number of eye conditions – over a period of several months. Also known as a port delivery system, the implant is inserted into the eye via a simple procedure and requires just two refills a year. Roche said in a statement that the implant could result in more reliable improvements in vision for people living with nAMD, reducing the risk of disease recurrence. Decreasing the need for frequent eye injections and doctor visits can also reduce the treatment burden for patients, the firm said. Singapore currently has four sites involved in the trial – the National University Hospital (NUH), Singapore General Hospital, Tan Tock Seng Hospital and Eye & Retina Surgeons @ Camden Medical, a private clinic. Professor Caroline Chee and Dr Yuen Yew Sen from the department of ophthalmology at National University Hospital who took part in the trial. -- ST PHOTO: DESMOND FOO Dr Yuen Yew Sen, a consultant with NUH's ophthalmology department, is among those involved in the Roche study here. He told The Straits Times only those who have recently been diagnosed with nAMD qualify for the trial, and four patients have received the implant at NUH. Once the treatment becomes available commercially – which he said could happen by 2026 – most patients should qualify for the treatment, except for those who have other eye conditions such as glaucoma. Beyond some initial minor discomfort following the surgery, patients who receive the implant are unlikely to notice it is even there, Dr Yuen said. 'Once the stitches dissolve, they don't actually feel anything,' said Dr Yuen, noting that similar implants are also used to treat conditions such as glaucoma. Such implants can also be used to treat other diseases related to the eyes, with trials looking at their use in addressing diabetic retinopathy on the cards, he said. Professor Gemmy Cheung, head of the retina research group at the Singapore Eye Research Institute, notes that nAMD presents differently in Asian populations due to the higher prevalence of a subtype known as polypoidal choroidal vasculopathy (PCV). 'PCV primarily impacts the blood vessels in the layer beneath the retina, causing serious vision impairment or even vision loss if left untreated,' she said. This is of concern because PCV has historically been considered more difficult to treat, with less predictable outcomes than typical nAMD, she said. While conventional treatments are effective in most PCV cases, frequent retreatment is required, said Prof Cheung, who also heads the medical retina department of the Singapore National Eye Centre. Lapses in treatment can result in reactivation of lesions and new instances of bleeding, she added. New therapies such as the port delivery system offer a 'promising approach to providing sustained disease control' in PCV, she said, adding they can potentially reduce the burden of frequent injections and improve long-term outcomes for patients. - The Straits Times/ANN

The project, led by private firm CMC Technology & Solution, located on an 11,000 sq.m site in Hanoi, will feature 23 floors above ground and three basements, with a total floor space exceeding 90,000 sq.m. Following the success of CMC's first creative space in Ho Chi Minh City - CCS Tan Thuan, this second facility will serve as an open artificial intelligence centre, dubbed It aims to house a comprehensive tech ecosystem, including a state-of-the-art data centre, research and development labs, training facilities, and a startup incubation zone, employing over 5,000 engineers. At the heart of the complex is the CMC Data Centre, designed to deploy cutting-edge technologies in artificial intelligence, cloud computing, cybersecurity, big data, and next-generation networks. The ecosystem will also integrate 25 core technologies developed by CMC. In his address, PM Chinh praised the project as a testament to the private sector's role in advancing Vietnam's technological ambitions, aligning with the Party's policy of making breakthroughs in sci-tech, innovation, and digital transformation. With Vietnam targeting at least 8% economic growth in 2025 and double-digit expansion thereafter, he called for national unity to drive prosperity, safeguard its independence, sovereignty, and territorial integrity. He urged CMC to lead in sci-tech, innovation and digital transformation, inspiring other businesses, educational establishments, and research centres, particularly young people, to contribute to Vietnam's rapid and sustainable development. He expressed his hope that CMC would grow into a major multinational corporation integrated into global value chains while prioritising social welfare and equitable access to technology, especially for remote and vulnerable communities. The Government will always accompany companies, including CMC, and request ministries, agencies, and Hanoi authorities to further support them by promptly removing any obstacles to their growth, he concluded. - Vietnam News/ANN

Trump to withdraw Musk's ally as nominee to head NASA
WASHINGTON: US President Donald Trump said Saturday he was withdrawing his nomination of tech billionaire Jared Isaacman, a close ally of Elon Musk, to lead space agency NASA. Trump said last December, before returning to office, that he wanted the online payments entrepreneur and the first private astronaut to conduct a spacewalk to serve as the next head of NASA. But on Saturday, he said on his Truth Social platform that "after a thorough review of prior associations, I am hereby withdrawing the nomination of Jared Isaacman to head NASA." "I will soon announce a new Nominee who will be Mission aligned, and put America First in Space." Featured Videos Earlier, the New York Times had reported the move was coming, quoting unnamed sources as saying the decision had come after the president learned Isaacman had donated money to prominent Democrats. Asked about that report, the White House had told AFP in an email that it was "essential that the next leader of NASA is in complete alignment with President Trump's America First agenda." "The Administrator of NASA will help lead humanity into space and execute President Trump's bold mission of planting the American flag on the planet Mars," it said. The nomination shakeup appears to be a snub of billionaire Musk, who on Friday stepped back from his role leading Trump's so-called Department of Government Efficiency (DOGE). Musk reportedly lobbied directly with the president for Isaacman, who has had significant business dealings with Musk's SpaceX, to get the top NASA job, raising questions of possible conflicts of interest. As the news surfaced, Musk stressed on X that "it is rare to find someone so competent and good-arted". The 42-year-old founder and CEO of Shift4 Payments has emerged as a leading figure in commercial spaceflight through his high-profile collaborations with SpaceX. He made history last September by stepping out of a Crew Dragon to gaze at Earth from the void of space while gripping the spacecraft's exterior, during the first-ever spacewalk carried out by non-professional astronauts. - AFP
