A Japanese water plant is harnessing the natural process of osmosis to generate renewable energy that could one day become a common power source.The possibility of generating power from osmosis — when water molecules pass from a less salty solution to a more salty one — has long been known.But actually generating energy from that has proved more complicated, in part due the difficulty of designing the membrane through which the molecules pass.Engineers in the city of Fukuoka and their private partners think they might have cracked it, and have opened what is only the world’s second osmotic power plant.It generates power from the transfer of molecules between treated sewage water and concentrated seawater, a waste product from a desalination plant in the city.”If osmotic power generation technology advances to the point where it can be practically used with ordinary seawater… this, in turn, would represent a major contribution to efforts against global warming,” said Kenji Hirokawa, manager at Sea Water Desalination Plant.Osmosis is familiar to most people. It is the process that, for example, causes water to seep out of a cucumber or eggplant when sprinkled with salt.Water molecules move across membranes from an area of low solution concentration to an area of higher concentrated solution.At scale, that movement can be significant enough to turn a turbine and thereby generate electricity.Desalination solutionFukuoka is particularly well-placed to benefit from the technology because it has a readily available source of extremely salty water — the brine leftover from desalination.With no major rivers to sufficiently source its water, the city and wider Fukuoka region of 2.6mn people have relied on a major desalination plant to produce drinking water since 2005.That left the city with large quantities of concentrated saline waste water to deal with.Ordinarily it is diluted and released back to the sea. Previous attempts to find alternatives, including salt making, failed to gain traction.Then engineering firm Kyowakiden Industry approached the city about harnessing the salty wastewater for osmotic power.”When our company rolls this out as a business, we aim to build plants roughly five to 10 times the scale of this current facility,” said Tetsuro Ueyama, research and development manager at the Nagasaki-based company.In Fukuoka’s system, a generator is attached to a local desalination plant located near a sewage treatment facility.It draws in highly saline waste water from the desalination plant and receives treated sewage.The two separate streams of liquid go through a number of chambers separated by semi-permeable membranes through which water molecules travel from the treated sewage toward the salty water.That process increases the volume, pressure and speed of the saline water flow, spinning a turbine that generates electricity before the now-diluted mixture is discharged to sea.The 700mn-yen ($4.4mn) power generation system came online last August, and once running at full capacity, it should generate up to 880,000 kilowatts annually, equivalent to the electricity consumption of 300 households.However it will remain devoted to supplying the power-thirsty facility, although it covers just a tiny fraction of its energy needs.Not ‘a pipe dream’The engineers involved, however, are dreaming big.The system will go through a five-year test to monitor its performance, including costs and maintenance, particularly for the membrane and other parts exposed to salt.Financial details of the project have not been disclosed, but engineers admitted that for now the system’s power costs “a lot more” than either fossil fuel or renewable energy.Pumping the water into the system also uses energy itself, and scaling up osmotic power for grid-level energy production has not yet been done anywhere in the world.Still, officials and experts believe the power source has a future, noting that unlike solar and wind, it is not dependent on weather or light.And the current high costs are partly because the company had to build a one-of-a-kind power plant, Ueyama said.Osmotic power has often been seen as primarily useful for estuary areas, where freshwater river flows meet the salty ocean.But Ueyama said the technique being used in Japan could be useful for countries with large desalination facilities like Saudi Arabia and other Middle Eastern nations.Kyowakiden is also working on technology that could generate similar power levels from less salty regular seawater.”First we want to popularise this technology from Fukuoka to the rest of Japan. In order for us to do that, we want to further upgrade our technology to create osmotic power generation that can use ordinary ocean water to generate electricity,” he said.”We don’t think this is a pipe dream.” Related Story Source link
An Indian-flagged tanker carrying LPG has safely passed through the Strait of Hormuz, India’s government said yesterday.Iran has effectively halted maritime traffic in the waterway, a critical route for global crude oil and gas, since US and Israeli strikes began on February 28. However, New Delhi, the world’s second-largest buyer of liquefied petroleum gas, has managed to secure passage for several Indian-flagged vessels over the past three weeks.The shipping ministry confirmed on Saturday that LPG carrier Green Sanvi had passed through the chokepoint. “Green Sanvi has safely transited the Strait of Hormuz, carrying 46,650 MT of LPG cargo with 25 seafarers on board,” a statement said, without giving further details of its final destination.It said 17 Indian-flagged vessels, carrying 460 Indian crew, “remain in the western Persian Gulf region”. Data from ship tracking company Marine Traffic’s website confirmed that the Green Sanvi was an Indian-flagged tanker.Public broadcaster All India Radio said it was the “seventh India-bound LPG tanker” to cross the Strait of Hormuz since the Middle East war began. India’s petroleum and natural gas ministry also said yesterday that Indian refiners were buying crude oil from Iran and other nations to help deal with the global energy crisis.“Amid Middle East supply disruptions, Indian refiners have secured their crude oil requirements, including from Iran,” it said in a post on X, adding that there was “no payment hurdle for Iranian crude imports”. That comes about two weeks after the US Treasury said it was temporarily lifting sanctions on Iranian oil already loaded onto vessels. The ministry also confirmed that an LPG vessel carrying around “44 TMT Iranian LPG” was berthed and “currently discharging” at the southwestern Indian port of Mangalore. India imports about 60% of its LPG needs and has been grappling with a gas crunch over the past month. The Indian government has imposed tighter controls over natural and cooking gas following import disruptions, prioritising supply towards households and limiting the amount available for industrial use. New Delhi maintains strong relations with Tehran but has steadily expanded cooperation with Israel in defence, agriculture, technology and cybersecurity. Source link
US President Donald Trump has signed an executive order aimed at regulating US collegiate sports in the wake of rule changes that allow student athletes to be compensated financially. The order, which is the second that Trump has issued on college sports, directs the National Collegiate Athletic Association (NCAA) to create rules that allow college athletes to play for “no more than a five-year period”. He also asked that rules be put in place that would allow them to transfer schools just once before they graduate without having to sit out a season.The changes are scheduled to go into effect on August 1, and institutions who allow athletes who don’t meet the criteria risk losing federal funding. Trump said that the loosening of “consistent rules or limits concerning eligibility, transfers, and pay-for-play schemes has created an out-of-control financial arms race… that is driving universities into debt”.Friday’s order came as the hugely popular NCAA basketball tournament reached its closing stages. The women’s semi-finals took place on Friday and the men’s Final Four semi-finals were scheduled for the weekend. In addition to demanding eligibility and transfer limits, it calls on governing bodies to ban “improper” financial arrangements and urges Congress to pass legislation to address the issues. It follows an order issued by Trump in July that sought to block some recruiting payments by third parties to college athletes in big-money sports like football and men’s basketball in order to preserve funds available for women’s and non-revenue sports. The president said last month that the rising value of name, image and likeness (NIL) contracts for players in high-visibility sports like football has created a burden for colleges that forces some to abandon other sports. Some of those sports – such as athletics, swimming and gymnastics – have long been pipelines for US Olympic teams. The NCAA long prohibited student athletes from accepting any compensation for use of their name, image and likeness, but after a 2021 Supreme Court ruling, the rules were changed so that some collegiate athletes could receive financial compensation.

US satellite imagery company Planet Labs said yesterday it will stop publishing high-resolution aerial pictures of the area involved in the Middle East war, following a request from President Donald Trump’s government. The US and Israel have conducted joint strikes against Iran since late February, prompting the Islamic Republic to retaliate with daily missile barrages targeting Israel and several neighbouring countries across the region. Planet said the US government had asked satellite imagery providers to implement an “indefinite withhold of imagery”. “Effective retroactively from March 9, 2026, Planet is moving to a managed access model, extending the publication delay for all new imagery within the designated AOI (area of interest), and releasing imagery on a case-by-case basis and for urgent, mission-critical requirements or in the public interest,” the company said in a message to clients received by AFP. This area was defined in a previous announcement as all of Iran and allied bases in the area, as well as in regional states and existing conflict zones. Planet, founded in 2010 by former Nasa scientists and whose images are widely used by media and researchers, said it expected the new policy to last until the end of the conflict. On March 10 the company said it would impose a two-week delay on access to its images of the Middle East because of the war, extending an initial 96-hour delay.Vantor, formerly Maxar, the other major provider of satellite imagery, had also announced major restrictions. Under normal circumstances, Planet’s images are available to its clients — including AFP — within hours of their satellites passing overhead, providing a valuable resource for businesses, researchers, and journalists, but also potentially for militaries seeking to target enemy military bases or radar sites. US law provides that any company headquartered in the US that commercially operates high-resolution satellite imagery may be subjected to restrictions for reasons of national security or foreign policy. In practice, satellite data providers, which operate under licence, put in place restriction protocols in order to avoid sanctions. Source link
NASA published the first images of Earth taken by astronauts aboard Artemis II as the crew travels toward the Moon.The mission carries Christina Koch, Victor Glover, Reid Wiseman, and Jeremy Hansen, marking the first crewed journey toward lunar orbit since the Apollo program.The spacecraft Orion reached the halfway point, about 219,000 km from Earth, and continues toward a planned lunar orbit in the coming days.Launched from Florida earlier this week, the mission follows a free-return trajectory, looping around the Moon before heading back to Earth.Artemis II is a key step toward returning humans to the lunar surface and preparing for future missions to Mars.

The Trump administration has fired army chief of staff General Randy George and two other senior figures, officials said Friday, in a surprise shake-up just as US forces are locked in a major war against Iran.Secretary of Defense Pete Hegseth’s ouster of George, the top US Army general, meant the latest in a series of high-profile departures from the military since President Donald Trump returned to power a year ago.There was little in the way of a public explanation for sacking George, a highly decorated veteran who oversaw the army at a time when the United States is more than a month into a punishing bombing campaign against Iran that Trump says will continue several weeks more.Pentagon spokesman Sean Parnell posted a statement on X late Thursday that George “will be retiring from his position… effective immediately.”During a nearly four-decade military career, George deployed to Iraq and Afghanistan multiple times and also served in positions including vice chief of staff of the army and senior military assistant to then-defense secretary Lloyd Austin during Joe Biden’s term as president.The army’s vice chief of staff General Christopher LaNeve will take over as acting chief of staff, CBS reported.Hegseth previously said LaNeve is “a battle-tested leader with decades of operational experience.”- Military purge -An official also confirmed that General David Hodne and Major General William Green Jr. were removed alongside George.Hodne led the Army’s Transformation and Training Command while Green was in charge of the Army’s Chaplain Corps.Trump has overseen a purge of top military officers, including the chairman of the Joint Chiefs of Staff, general Charles “CQ” Brown, whom he fired without explanation in February 2025, shortly after taking office.Other senior officers dismissed include the heads of the Navy and Coast Guard, the general who headed the National Security Agency, the vice chief of staff of the Air Force, a Navy admiral assigned to NATO, and three top military lawyers.The chief of staff of the Air Force also announced his retirement without explanation just two years into a four-year term, while the head of US Southern Command retired a year into his tenure.Hegseth has insisted the president is simply choosing the leaders he wants, but Democratic lawmakers have raised concerns about the potential politicization of the traditionally neutral US military.Last year, the Pentagon chief additionally ordered at least a 20 percent cut in the number of active-duty four-star generals and admirals in the US military, as well as a 10 percent cut in the overall number of general and flag officers.wd/mjf/hol/sms* Defense Secretary Pete Hegseth rapidly reshaping Pentagon leadership, firing top officials* No official reason given for George’s removal amid US military buildup in Middle East* General Christopher LaNeve to serve as acting Army chief (Updates April 2 story with comment from joint staff in paragraphs 9-10)By Idrees Ali and Phil StewartWASHINGTON, April 2 (Reuters) – U.S. Army Chief of Staff Randy George was fired on Thursday by Defense Secretary Pete Hegseth, three U.S. defense officials told Reuters, a major staffing change that comes as the U.S. military fights a major war in the Middle East.Even as Hegseth, a former Fox News host, has moved quickly to reshape the department, firing the head of a military branch during wartime is extremely rare.The Pentagon confirmed that George, who had more than a year left in his term, “will be retiring from his position as the 41st Chief of Staff of the Army effective immediately.”Two of the officials, speaking on the condition of anonymity, said Hegseth has also fired General David Hodne, who leads the Army’s Transformation and Training Command, and Major General William Green, head of the Army’s Chaplain Corps.George’s removal adds to recent upheaval at all levels of leadership at the Pentagon, including the firing last year of the previous chairman of the Joint Chiefs of Staff, Air Force General C.Q. Brown, as well as the chief of naval operations and Air Force vice chief of staff.The department did not give a reason for George’s departure, which comes as the U.S. military builds up its forces in the Middle East while carrying out operations against Iran.The U.S. strikes in the region are largely being carried out by the Navy and Air Force, although U.S. Army soldiers have been dispatched to the Middle East for air defense systems. The Army is the largest branch of the U.S. military, with about 450,000 active-duty soldiers.Thousands of soldiers from the U.S. Army’s elite 82nd Airborne Division have also started arriving in the Middle East, potentially for ground operations in Iran.In a statement, the Pentagon’s Joint Staff thanked George for his service.”Since 1988, General George and his family have consistently answered the nation’s call with honor and dedication,” the Joint Staff said.LATEST UPHEAVAL AT PENTAGONThere had been no public signs of friction between Hegseth and George, even as Hegseth pursued controversial moves such as firing the Army’s top lawyer and arranging a massive military parade to celebrate the Army’s 250th birthday, which coincided with Trump’s birthday.Earlier this week, Hegseth also reversed an Army decision to investigate Army pilots who were flying attack helicopters near singer Kid Rock’s house, in an apparent show of support for the vocal Trump backer.CBS News, which first reported the dismissal, said it was not related to the Kid Rock incident.One of the officials said Hegseth’s former military aide and Army vice chief of staff, General Christopher LaNeve, will take over George’s role in an acting capacity.Another of the officials added that senior Army leadership learned about George’s firing at the same time as it was made public.George, an infantry officer who served in Iraq and Afghanistan, was confirmed to the top Army post in 2023. Terms in that role usually run for four years.Prior to holding the top job, George was the vice chief of the Army and, before that, the senior military adviser to then-Defense Secretary Lloyd Austin.He was considered close to Army Secretary Dan Driscoll. The two worked together to take on large defense companies, in the Army’s drive to speed up weapons development and drive down costs.The office for George did not immediately respond to a request for comment.

WHO urges urgent support for strained health systems in countries affected by Mideast conflict
The World Health Organization (WHO) has called on donors to urgently support health systems in countries affected by the ongoing escalation in the Middle East, warning that services are under severe strain after weeks of intensified hostilities.WHO Director-General Tedros Adhanom Ghebreyesus said in a post on the X platform that health systems in Lebanon, Iran, Iraq, Syria and Jordan are facing mounting pressure amid rising casualties and displacement.The WHO has launched a $30.3 million flash appeal to sustain its health response across the five countries, covering the period from March to August 2026. The agency said the funding is critical to maintaining life-saving health services as hospitals grapple with surging trauma cases while struggling to continue routine care.According to WHO, the conflict has displaced more than 4.3 million people, with thousands killed and tens of thousands injured, placing unprecedented strain on already fragile health systems.The appeal will prioritize trauma and emergency care, ensure continuity of essential health services, and strengthen disease surveillance and early warning systems to prevent outbreaks. It will also support mass casualty management and enhance preparedness for chemical, biological, radiological and nuclear (CBRN) risks. Source link
The French government announced the launch of an emergency loan program to support small and medium-sized enterprises affected by rising fuel prices due to the escalation in the Middle East.In a statement, the Ministry of Economy revealed that companies operating in the transport, agriculture, and fisheries sectors will be eligible for fast-track fuel loans of up to 50,000 Euros.The ministry also said that the interest rate on the loans will be 3.8%, with repayment periods of up to three years. It noted that the program fulfills a commitment made last week by French Prime Minister Sebastien Lecornu, whose government is seeking to contain the economic repercussions of rising oil prices caused by the war.
