U.S. and Australian officials said on Monday (July 8) that both countries are committed to improving financial connectivity in the Pacific and strengthening banking services in the region to resist China's growing covetousness. According to Reuters, at the two-day Pacific Banking Forum co-hosted by the United States and Australia, Australian Assistant Treasurer Stephen Jones said that Canberra hopes to be the partner of choice in the Pacific region, both in banking and defense. "If there are countries acting in this region whose main goal is to promote their own national interests rather than the interests of Pacific island countries, we will be very concerned," Jones said at the first day of the forum in Brisbane. He made this comment when asked about Chinese banks filling the vacuum in the Pacific region. The report said that as some Western banks have interrupted their long-standing business relationships with banks in small Pacific island countries, while others are preparing to close their businesses, these Pacific island countries face many challenges and their ability to obtain US dollar-dominated banking business is limited. The report said that experts said that Western banks are taking de-risking actions to meet financial regulations, which makes it more difficult to do business in Pacific island countries. This in turn weakens the financial resilience of these island nations. At the same time, Washington is also stepping up efforts to support Pacific island nations in limiting China's influence. Brian Nelson, U.S. Treasury Undersecretary for Counterterrorism and Financial Intelligence, said, "We recognize the economic and strategic importance of the Pacific region, and we are committed to deepening engagement and cooperation with our allies and partners to enhance financial connectivity, investment and integration." The report said that neither the United States nor Australia has yet announced detailed plans at the forum, but comments from officials from both countries reflect the growing unease among Western countries that have traditionally had influence in the Pacific region about China's growing influence in the region.

A provocative new study reveals the complex effects of the space environment on human health, providing insight into potential damage to blood, cell structure and the immune system. The study focused on SpaceX's Inspiration4 mission, which successfully sent two men and two women into space in 2021 to orbit the Earth for three days and shed some light on the effects of space travel on the human body. The research data, derived directly from the Inspiration4 mission, shows that even a brief trip to space can significantly damage the human immune system, trigger an inflammatory response, and profoundly affect cell structure. In particular, space travel triggered unprecedented changes in cytokines that play a key role in immune response and muscle regulation but are not usually directly associated with inflammation. In particular, the study found a significant increase in muscle factors, which are physiological responses specific to skeletal muscle cells in microgravity, rather than a simple immune response. Although non-muscular tissues did not show changes in proteins associated with inflammation, specific leg muscles such as soleus and tibialis anterior muscles showed significant signs of metabolic activity, especially increased interleukin in the latter, further enhancing the activation of immune cells.

Japan and the Philippines signed an important defense agreement, and the two sides became "quasi-allies". On July 8, local time, Japan and the Philippines signed the "Reciprocal Access Agreement" in Manila. The agreement will relax restrictions on the movement of personnel between the Japanese Self-Defense Forces and the Philippine military during joint exercises, mutual visits and other operations in each other's countries. In response, Chinese Foreign Ministry spokesman Lin Jian responded at a regular press conference on the 8th that exchanges and cooperation between countries should not undermine mutual understanding and trust between regional countries, should not undermine regional peace and stability, and should not target third parties or undermine the interests of third parties. The Asia-Pacific region does not need military groups, let alone "small circles" that provoke camp confrontation and instigate a "new Cold War". Any actions that undermine peace and stability in the region and undermine unity and cooperation in the region will arouse the vigilance and common opposition of the people in the region. Japan and the Philippines upgraded to a "quasi-alliance" relationship On the same day, a "2+2" meeting attended by the foreign ministers and defense ministers of Japan and the Philippines was held in Manila. Japanese Defense Minister Minoru Kihara and Foreign Minister Yoko Kamikawa attended the talks with Philippine Defense Minister Gilbert Teodoro and Foreign Minister Enrique Manalo. This is the second Japan-Philippines "2+2" meeting. The last one was held in Tokyo in April 2022. Witnessed by Philippine President Marcos, the two sides signed the "Reciprocal Access Agreement". Marcos expressed the hope that the bilateral relations between the Philippines and Japan and the trilateral cooperation between the Philippines, Japan and the United States will be further deepened. The "Reciprocal Access Agreement" is also known as the "Military Visits Agreement". Military and defense cooperation between sovereign states, especially sending troops into each other's territory, usually faces complicated procedures and other problems. In order to simplify the procedures, the two countries will reach relevant agreements to simplify the approval procedures for the entry of troops from both sides into each other's countries, and facilitate mutual visits and joint military activities between the two countries' troops. The "Reciprocal Access Agreement" was born. Take the "Reciprocal Access Agreement" signed by Japan and Australia (full name "Agreement between Japan and Australia on Promoting Mutual Access and Cooperation Facilitation between the Japanese Self-Defense Forces and the Australian Defense Force") as an example. The agreement has 29 articles, covering many areas such as entry and exit procedures for troops, jurisdiction, taxation, cost burden and compensation. The key is to simplify the entry and exit procedures for visiting troops and their members, ships, aircraft, etc., relax restrictions on the transportation of weapons, ammunition and materials carried by visiting troops, and provide a legal basis for the two countries' troops and weapons and equipment to enter each other's territory. Japan and the Philippines signed the "Reciprocal Access Agreement", making the Philippines the third country to conclude this agreement with Japan after Australia and the United Kingdom. Cai Liang, Secretary-General and Researcher of the China-Japan Relations Research Center of the Shanghai Institute for International Studies, analyzed to The Paper (www.thepaper.cn) that Japan and the Philippines have their own strategic considerations for signing the "Reciprocal Access Agreement". As for the Philippines, due to its limited strength, it does not exclude any foreign power willing to strengthen military cooperation with the Philippines from intervening in the South China Sea situation. Therefore, it can be seen that in the past two years, the Philippines has actively promoted Australia, France, India and other countries to intervene in the South China Sea and strengthen military cooperation with them, involving intelligence, weapons and equipment, and training and exercises. "Japan's purpose is very simple. Strengthening military cooperation with the Philippines is to strategically balance China. The United States and the Philippines are allies, and the US-Japan alliance has been upgraded to a 'quasi-alliance'. The military cooperation between the United States, Japan and the Philippines has been upgraded to a new level." Cai Liang said, "The signing of an important defense agreement between Japan and the Philippines will make it easier for Japan to intervene in the South China Sea situation and seek the 'three seas linkage' of the East China Sea, the South China Sea, and the Taiwan Strait, in order to better respond to China's strategy and enhance its international influence." As for whether the signing of the "Reciprocal Access Agreement" means that Japan will deploy the Self-Defense Forces in the Philippines, Cai Liang pointed out that this agreement only simplifies the procedures for the troops of both sides to enter each other's territory, and is more suitable for short-term training, military exercises, etc., and is not a long-term deployment of the Self-Defense Forces in the Philippines. The two countries deepen military cooperation The Philippine presidential office also said in a statement that Japan is one of the four major strategic partners of the Philippines, and the two countries have established a strategic partnership for more than ten years. It seems no coincidence that Japan and the Philippines signed the "Reciprocal Access Agreement" at this time. Recently, China-Philippines relations have become tense around the situation in the South China Sea. The Global Times quoted Japan's Kyodo News Agency as saying that the two sides are seeking to strengthen cooperation against China. Minoru Kihara said last week: "The Philippines is located in a strategically important region, occupies a key position on Japan's sea lanes, and is also an ally of the United States. Joint training and strengthening cooperation with the Philippines are of great significance to the realization of a 'free and open Indo-Pacific region'." Cai Liang said that Japan's intervention in the South China Sea situation is mainly to reduce strategic pressure in the East China Sea and southwest of Japan, but it is not conducive to peace and stability in the South China Sea. It is reported that Japan and the Philippines began negotiations on the agreement in November last year. The signing of the "Reciprocal Access Agreement" by the two sides lays the foundation for the two countries to strengthen bilateral and even multilateral military cooperation in the future. The Japanese government intends to allow the Self-Defense Forces to formally participate in the annual US-Philippines "Shoulder to Shoulder" joint exercises around the Philippines after the agreement comes into effect. The Self-Defense Forces previously participated in the "Shoulder to Shoulder" exercises as observers, and will be able to formally participate after signing the agreement. In April this year, the United States and the Philippines held the largest "Shoulder to Shoulder" exercise to date, involving 5,000 Philippine personnel and 11,000 US personnel. The military exercise also included about 150 Australian military personnel and 100 French naval personnel. According to the plan, 14 countries including Japan and India sent personnel as observers. The "Typhon" medium-range missile launch system deployed by the US military on Luzon Island in the Philippines for the first time participated in the exercise, which aroused great attention from all walks of life. In terms of weapons and equipment exports, Japan and the Philippines have gradually strengthened military cooperation in recent years. The Philippines recently agreed to purchase five Coast Guard patrol ships from Japan to enhance its patrol capabilities in the South China Sea. Defense News reported in November last year that the Philippines had received an early warning radar system from Japan in 2023, the first major equipment transfer since the Japanese government lifted the postwar defense export ban in 2014. The Japanese Ministry of Foreign Affairs stated that Kamikawa mentioned topics such as defense equipment transfer, "government security capability enhancement support" (OSA), and economic and trade cooperation. The OSA project was created by the Kishida government and plans to allocate billions of yen in budget to assist the military construction of the Philippines and other countries, including providing the Philippines with 5 sets of coastal surveillance radars. Regarding Japan's relaxation of restrictions on defense equipment exports, the Chinese Ministry of Defense previously responded that Japan has continuously broken through the constraints of the "peace constitution" and the principle of "exclusive defense", and has been making small moves in the field of military security, which has aroused high vigilance and strong concern from the international community. China requires Japan to deeply reflect on its history of aggression, attach importance to the security concerns of its Asian neighbors, adhere to the path of peaceful development, and win the trust of its Asian neighbors and the international community with practical actions.

The Sun is extremely active right now, blasting the Earth with the biggest solar storms in 20 years. This is what it is doing to the rest of the Solar System. If you happened to look skywards on a few nights in May 2024, there was a good chance of seeing something spectacular. For those at relatively low latitudes, there was a rare chance to see the flickering red, pink, green glow of our planet's aurorae. A powerful solar storm had sent bursts of charged particles barrelling towards Earth and, as they bounced around in our planet's atmosphere, they unleashed spectacular displays of the Northern and Southern Lights. The dazzling displays of aurora borealis were visible far further south than they might normally be – and far further north in the case of aurora australis thanks to the power of the geomagnetic storm, the strongest in two decades. Although some people experienced only a faint, eerie glow, others were treated to a myriad of colour as far south as London in the UK and Ohio in the US. Reports even came in from just to the north of San Francisco, California. But while this spike in activity from the Sun left many on Earth transfixed by the light display it produced, it has also had a profound effect elsewhere in the Solar System. As most of us wondered at the colours dancing across the night's sky, astronomers have been peering far beyond to see the strange ways such intense bursts of particles affect other planets and the space between them. "The Sun can fire material outwards in any direction like a garden sprinkler," says Jim Wild, a professor of space physics at Lancaster University in the UK. "The effects are felt throughout the Solar System." Our Sun is currently heading towards, or has already reached, its solar maximum – the point in an 11-year cycle where it is most active. This means the Sun produces more bursts of radiation and particles from solar flares and events known as coronal mass ejections (CMEs). If these are sprayed in our direction, they can supercharge the Earth's magnetic field, causing magnificent aurorae but also posing problems for satellites and power grids. "Things really seem to be picking up right now," says Mathew Owens, a space physicist at the University of Reading in the UK. "I think we're about at solar maximum now, so we may see more of these kinds of storms in the next couple of years." Around the Sun, multiple spacecraft are observing this increase in activity up close. One of those, the European Space Agency's (Esa) Solar Orbiter, has been studying the Sun since 2020 on an orbit that takes it within the path of Mercury. Currently the spacecraft is "on the far side of the Sun as seen from Earth", says Daniel Müller, project scientist for the Solar Orbiter mission at Esa in the Netherlands. "So we see everything that Earth doesn't see." The storm that hit Earth in May originated from an active region of solar flares and sunspots, bursts of plasma and twisting magnetic fields on the Sun's surface, known as its photosphere. Solar Orbiter was able to see "several of the flares from this monster active region that rotated out of Earth's view", says Müller, bright flashes of light and darkened regions called sunspots on the Sun's surface. One of the goals of Solar Orbiter is "to connect what's happening on the Sun to what's happening in the heliosphere," says Müller. The heliosphere is a vast bubble of plasma that envelops the Sun and the planets of the Solar System as it travels through interstellar space. What Müller and his colleagues hope to learn more about is where the solar wind – the constant stream of particles spilling out from the Sun across the Solar System – "blows into the interstellar medium", he says. "So we are particularly interested in anything energetic on the Sun that we can find back in the turbulence of the solar wind." This particular cycle, cycle 25, appears to be "significantly more active than what people predicted", says Müller, with the relative sunspot number – an index used to measure the activity across the visible surface of the Sun – eclipsing what was seen as the peak of the previous solar cycle. The National Oceanic and Atmospheric Administration (Noaa) in the US had predicted a maximum monthly average of 124 sunspots a day in May, but the actual number was 170 on average, with one day exceeding 240, according to Müller. But the exact cause of the Sun's 11-year-long cycle and its variabilities remains a bit of a mystery. • Alien aurora: The strange displays that light up other worlds • Why Einstein was wrong about black holes • The Moon is slipping away from the Earth – and our days are getting longer The effects of these changes in solar activity, however, extend far across the Solar System. Earth is not the only planet to be hit by solar storms as they billow across interplanetary space. Mercury, the closest planet to the Sun, has a much weaker magnetic field than Earth – about 100 times less – and lacks a substantial atmosphere. But solar activity can cause the surface of the planet to glow with X-rays as solar wind rains down. Venus also lacks a substantial magnetic field, but the planet does still create auroras as the solar wind interacts with the planet's ionosphere. At Mars, the effect of solar activity is more obvious. Here, a Nasa spacecraft called Maven (Mars Atmosphere and Volatile Evolution) has been studying the planet's atmosphere from orbit since 2014. "We were on the declining side of solar cycle 24 [then]," says Shannon Curry, a planetary scientist at the University of Colorado, Boulder in the US and the lead on the mission. "We are now coming up on the peak of cycle 25, and this latest series of active regions has produced the strongest activity Maven has ever seen." Between 14 and 20 May the spacecraft detected exceptionally powerful solar activity reaching Mars, including an X8.7 – solar flares are ranked B, C, M, and X in order from weakest to strongest. Results from the event have yet to be studied, but Curry noted that a previous X8.2 flare had resulted in "a dozen papers" published in scientific journals. Another flare on 20 May, later estimated to be an even bigger X12, hurled X-rays and gamma rays towards Mars before a subsequent coronal mass ejection launched a barrage of charged particles in the same direction. Images beamed back from Nasa's Curiosity Rover on Mars revealed just now much energy struck the Martian surface. Streaks and dots caused by charged particles hitting the camera's sensors caused the images to "dance with snow", according to a press release from Nasa. Maven, meanwhile, captured glowing aurora as the particles hit the Mars' atmosphere, engulfing the entire planet in an ultraviolet glow. The flares can cause the temperature of the Martian atmosphere to "dramatically increase," says Curry. "It can even double in the upper atmosphere. The atmosphere itself inflates. The entire atmosphere expands dozens of kilometres – exciting for scientists but detrimental for spacecraft, because when the atmosphere expands there's more drag on the spacecraft." The expanding atmosphere can also cause degradation of the solar panels on spacecraft orbiting Mars from the increase in radiation. "The last two flares caused more degradation than what a third of a year would typically do," says Curry. Mars, while it has lost most of its magnetic field, still has "crustal remnant magnetic fields, little bubbles all over the southern hemisphere", says Curry. During a solar event, charged particles can light those up and excite particles. "The entire day side lights up in what we call a diffuse aurora," says Curry. "The entire sky glows. This would most likely be visible to astronauts on the surface." By the time solar storms reach further out into the solar system, they tend to have dissipated but can still have an impact on the planets they encounter. Jupiter, Saturn, Uranus, and Neptune all have aurorae that are in part driven by charged particles from the Sun interacting with their magnetic fields. But one of the key effects of solar activity on interplanetary space that astronomers are eager to study is something called "slow solar wind", a more sluggish, but denser stream of charged particles and plasma from the Sun. Steph Yardley, a solar astronomer at Northumbria University in the UK, says solar wind is "generally classed about 500km/s (310 miles/s)", but slow wind falls below this. It also has a lower temperature and tends to be more volatile. Recent work by Yardley and her colleagues, using data from Solar Orbiter, suggests that the Sun's atmosphere, its corona, plays a role in the speed of the solar wind. Regions where the magnetic field lines, the direction of the field and charged particles are "open" – stretching out into space without looping back – provide a highway for solar wind to reach high speeds. Closed loops over some active regions – where the magnetic field lines have no beginning and end – can occasionally snap, producing slow solar wind. The variability in the slow solar wind seems to be driven by the unpredictable flow of plasma inside the Sun, which makes the magnetic field particularly chaotic. The X-class flares and coronal mass ejections seen in May transformed the interplanetary medium as they flung out material across the solar system. Solar Orbiter detected a huge spike in ions moving at thousands of kilometres per second immediately after the 20 May flare. Computers on board other spacecraft – the BepiColombo probe, which is currently on a seven-year journey to Mercury, and Mars Express, in orbit around the Red Planet – both saw a dramatic increase in the number of memory errors caused by the high energy solar particles hitting the memory cells. The day after the coronal mass ejection, magnetometers on board the Solar Orbiter also saw large swings in the magnetic field around the spacecraft as a huge bubble of plasma made up of charged particles thrown out from by the event washed past it at 1,400km/s (870 miles/s). Increased solar activity is a boon for scientists. "If you track the number of papers produced by solar physicists, you can almost see an 11-year cycle in there," says Owens. "We are all more scientifically productive when there's a lot of activity to study." As the Sun continues into solar maximum, the Solar System will see more and more activity streaming from its surface. Yet while all the planets witness at least some of the activity, our planet bears the brunt more than most. "Earth is slightly unique in that space weather can have interesting effects on human technologies," says Wild. "There's an extra dimension here on Earth." Perhaps one day those anthropogenic effects might be felt elsewhere, too. "If you're going to fly to Mars and you have a six-month flight through the interplanetary environment, you're going to potentially suck up a lot of space weather events," says Wild. "How you protect your astronauts is an interplanetary issue that we need to get our heads around."

LONDON, July 5 (Reuters) - Insurers are nervous that militant attacks or AI-generated fake images could derail the Paris Olympics, risking event cancellations and millions of dollars in claims. Insurers faced losses after the 2020 Tokyo Olympics were postponed for a year due to the COVID-19 pandemic. Since then, wars in Ukraine and Gaza and a spate of elections this year, including in France, have driven up fears of politically-motivated violence at high-profile global events. The Olympics take place in Paris from July 26-Aug 11 and the Paralympics from Aug 28-Sept 8. German insurer Allianz (ALVG.DE), opens new tab is insurance partner for the Games. Other insurers, such as the Lloyd's of London (SOLYD.UL) market, are also providing cover. "We are all aware of the geopolitical situation the world is in," said Eike Buergel, head of Allianz's Olympic and Paralympic programme. "We are convinced that the IOC (International Olympic Committee), Paris 2024 and the national organising committees, together with the French authorities, are taking the right measures when it comes to challenges on the ground."
