SCHRODINGERS NASRALLAH


Reuters: Hezbollah leader Hassan Nasrallah alive after Israeli airstrikes

By Fidel Rahmati
- September 28, 2024


Following a heavy airstrike by Israeli warplanes on Hezbollah’s headquarters in the suburbs of Beirut, Reuters, citing a source close to Hezbollah, reported that Hassan Nasrallah, the group’s Secretary-General, is alive.

Israeli media reported that the target of the Israeli airstrike in southern Beirut was Hezbollah’s Secretary-General.

The Israeli army announced on Friday that it had attacked Hezbollah’s main headquarters in southern Lebanon.

Fox News, quoting Israeli sources, confirmed that the target of the Israeli airstrike on Hezbollah’s command center was Hassan Nasrallah.

Al-Arabiya reported that Israel bombed the Dahiyeh area in the southern suburbs of Beirut, with at least ten strikes carried out in the area within minutes.

A Hezbollah official stated that six buildings were completely destroyed in the Israeli airstrike.

Daniel Hagari, the Israeli army spokesperson, said in a televised statement that Hezbollah’s central command is located deep within civilian areas.

Security sources in Lebanon confirmed that the attack targeted an area usually occupied by senior Hezbollah officials.

Reuters reported that this was the heaviest attack in Beirut during the year-long conflict between Hezbollah and Israel.

Tasnim News Agency, affiliated with Iran’s Islamic Revolutionary Guard Corps, cited security sources reporting that “Hassan Nasrallah is in a safe location.”

This attack coincided with Israeli Prime Minister Benjamin Netanyahu’s speech at the United Nations General Assembly.

Netanyahu referred to Hezbollah as “the essence of global terrorist organizations” and added, “We will continue to weaken Hezbollah until we achieve our goal. We are committed to eliminating the curse of terrorism that affects the entire world.”

Dubai: The Israel Defense Forces (IDF) has reportedly confirmed they have killed Hezbollah leader Hassan Nasrallah in airstrikes that targeted Southern Suburbs of Beirut last night.

"Hassan Nasrallah is dead," military spokesman Lieutenant Colonel Nadav Shoshani announced on X. Military spokesman Captain David Avraham also confirmed to AFP that the Hezbollah chief had been "eliminated" following strikes Friday on the Lebanese capital.

Contact lost

A source close to Lebanon's Hezbollah group said Saturday contact had been lost since last evening with chief Hassan Nasrallah, after Israel said it had "eliminated" him in a strike on the group's southern Beirut bastion.

"Contact with Sayyed Hassan Nasrallah has been lost since Friday evening," said the source, requesting anonymity to discuss sensitive matters. He did not confirm whether Nasrallah had been killed.

Ali Karki also killed

The strikes, carried out late Friday night, also reportedly killed senior Hezbollah commander Ali Karki, alongside other key figures in the group.

The confirmation followed initial reports from Israeli media that Israel’s security services had conclusive proof of Nasrallah’s death during a major assassination operation.

How it happened

The airstrikes targeted Hezbollah’s central military headquarters, located in a heavily fortified underground facility beneath a residential building in the Dahieh district of Beirut, a stronghold of the militant group.

The IDF's statement noted that the attack was based on intelligence from Israel's Mossad and was launched while Hezbollah’s leadership was inside the headquarters coordinating operations.

Nasrallah, who led Hezbollah for 32 years, was the principal architect behind the group’s military and terrorist activities, which included attacks on Israeli civilians and soldiers, as well as operations abroad.

Nasrallah, a 64-year-old Shiite cleric, took control of Hezbollah in 1992 after his predecessor, Abbas Al Musawi, was assassinated by Israeli forces.

Under Nasrallah’s leadership, Hezbollah became not only a dominant political party in Lebanon but also an entity with a robust military presence, wielding significant influence across the region.

Nasrallah’s tenure included leading the fight against Israel’s occupation of southern Lebanon, ultimately forcing Israeli forces to withdraw in 2000 without a peace treaty.

The airstrikes and subsequent confirmation of Nasrallah’s death come amid heightened tensions between Israel and Hezbollah, as well as growing concerns about the potential for broader conflict in the region.

The IDF emphasized that Nasrallah, throughout his leadership, was directly responsible for orchestrating thousands of terrorist acts and the deaths of countless Israeli civilians and soldiers.


Strikes continue


The Israeli military said it struck dozens of Hezbollah targets on Saturday in eastern and southern Lebanon, as the Lebanese armed group fired rockets into northern Israel.

Saturday morning's wave of Israeli strikes followed intense overnight bombardment targeting Hezbollah's southern Beirut stronghold, the site of a massive Israeli attack on Friday that flattened several residential buildings.

"The IAF (air force) conducted extensive strikes on dozens of terror targets belonging to the Hezbollah terrorist organisation in the area of Beqaa (east) and in different areas of southern Lebanon," the military said in a statement.

Air raid sirens sounded across northern Israel early on Saturday, warning of a barrage of rockets being fired from across the border.



Israel takes on Iran by neutralising Hassan Nasrallah

That the Israelis caught Nasrallah unawares in his Beirut bunker last night shows the level of precise actionable intelligence and deadly targeting


The targeted assassination of Hezbollah’s terrorist in-chief Hassan Nasrallah by Israeli Air Force after neutralising top Radwan force commanders, pager explosions and walkie-talkie explosions within the Iran-backed Shia groups shows deep penetration of Israeli agencies inside the Lebanon-based Islamist group.
Iranian leader Al Khamenei with killed Hezbollah's Hassan Nasrallah and assassinated IRGC head Qassem Suleimani

Sixty-four-year-old Nasrallah was the principal cat’s paw of Ayatollahs of Iran as he ran the brutal Islamic group for the past three decades, taking on the powerful Israelis head-on during the occupation of southern Lebanon and then 2006 land war which ended in a stalemate.
That the Israelis caught Nasrallah unawares in his Beirut bunker last night shows the level of precise actionable intelligence and deadly targeting through laser-guided concrete penetrating bombs by the Israeli Air Force.

Presently, the majority of the population in north and central Israel are hiding in bomb shelters fearing Hezbollah and Iran retaliation post-killing of Nasrallah.
Hassan Nasrullah was favourite of Ayatollah Khamenei

Although Iran has been using Shia Houthis, Sunni Hamas, and Shia Kaitab Hezbollah in Iraq, Nasrallah, and his Lebanon-based group is the closest to the Iranian clergy and its strong arm—the QUDS force.

The killing of Nasrallah along with the deaths of senior commanders since the pagers exploded must be a serious setback for Tehran as the son of a vegetable seller was a favourite of Ayatollah Khomeini.

It was Khomeini’s 1979 Iranian revolution that radicalized the Hezbollah cadre and made them into fighters after taking training from Islamic Revolutionary Guard Corps of Iran. Hezbollah supported Syrian dictator Bashar al-Assad and virtually captured the once-Christian Lebanon.

Nasrallah ran afoul with Israel after Hezbollah launched rocket attacks into the north of Jew nation in support of Hamas post-October 7 massacre. In a span of two months, Israel has severely degraded Hezbollah’s fighting capabilities after killing top commanders like Fuad Shukr and Ibrahim Aqil in targeted strikes.

The losses of top and middle-level Hezbollah commanders will make it very difficult for Iran to appoint the successor of Nasrallah as even his deputy has been taken out by Tel Aviv.

Just like Hamas, Hezbollah is an ideology that cannot die despite its top leader being exterminated. The Israeli borders with Lebanon and Gaza will remain hot and so will be the skies with missiles being fired by Houthis in Yemen. The death of Nasrallah may trigger a strong retaliation from Iran but the missile capabilities of Tehran are limited in range and effectiveness.

After taking out Hamas’ Ismail Haniyeh in Tehran, Nasrallah in Lebanon, Israel has taken the fight to Iran. The ball is now in Ali Khamenei’s court as his credibility is at stake.


Iran Supreme Leader next? Tehran moves Ayatollah Khamenei to secure spot after IDF says Hezbollah chief killed

Iran Supreme Leader Ayatollah Ali Khamenei has been moved to safer place within the country and security has been beefed up after Israeli military said Tehran-backed Hezbollah chief Hassan Nasrallah was killed in the Beirut strike, said a report.

The sources quoted by Reuters said Iran was in constant touch with Hezbollah to decide on its next move.

Iran's move comes after Israeli army chief said the IDF has not emptied its "toolbox" with Nasrallah's assassination. Chief of the General Staff Herzi Halevi said "the message is simple: Anyone who threatens the citizens of Israel – we will know how to reach them."

Hezbollah leadership was meeting at their undrground headquarters in south Beirut when the Israeli military launched its precision attack.

Hezbollah is yet confirm if Nasrallah has been killed. Earlier, a spokesperson of the group said the Hezbollah chief was fine and not in the targeted location.

Reports also said Nasrallah's daughter Zainab Nasrallah, Hezbollah missile unit commander Muhammad Ali Ismail and his deputy Hossein Ahmed Ismail were also killed in IDF strikes.

Israel had activated three batallions of reserve soldiers amid recent attacks in Lebanon.
 





ANALYSIS

Strikes on Beirut’s southern suburbs, the fate of Nasrallah: how to explain Hezbollah’s silence

The party's media continues its coverage of the war as if nothing has happened.

The Israeli army announced on Saturday that it had succeeded in assassinating, in a lethal strike on the southern suburbs of Beirut the day before, the all-powerful secretary-general of Hezbollah, Hassan Nasrallah. An event whose shockwaves are likely to be felt across the region, as Nasrallah was a key figure in the pro-Iranian axis. He is sometimes even described as the number two in this camp, behind Supreme Leader Ali Khamenei.

During the night from Friday to Saturday, the southern suburb, a Hezbollah stronghold and densely populated area, was bombarded throughout the night. But on Hezbollah’s side, it’s radio silence. The party's media,such as its al-Manar channel or the al-Ahed website, do not mention Israeli allegations about this assassination or the uncertainty about Hassan Nasrallah's fate.

On the contrary, these two outlets continue their coverage of the war as if nothing had happened. Similarly, the party's official communication channels simply announce the various operations it is conducting against Israel. A resounding silence that raises many questions.

What we know


After the violent Israeli strike on Friday against the southern suburbs of Beirut, which, according to Tel Aviv, targeted the party's headquarters, sources close to Hezbollah told Reuters that the organization had lost contact with its leader. At the same time, other party insiders, such as journalist Faisal Abdel Sater, claimed that Hassan Nasrallah was still alive. The next day, the Israelis announced they had evidence of the "success" of their operation, which Hezbollah has not commented on.


The hypotheses

Hezbollah's silence regarding the fate of its secretary-general could simply be due to the fact that the party itself does not know if Hassan Nasrallah has survived the strike or not. This is reminiscent of the assassination by Israel of the chief of staff of the organization, Fouad Chukur, last August. It took a day for his body to be found and his death confirmed. In the meantime, contradictory information was constantly circulating.

Hezbollah has all the more reason to refrain from making statements on the subject since Nasrallah has developed, over his years at the head of the powerful Shiite organization, an almost divine image in the eyes of his most loyal supporters. Announcing uncertainty about his fate, or even his death, could cause panic and mobilization in the streets, especially in Shiite regions that have been continuously bombarded by the Israeli army since Friday evening.

Another hypothesis that circulates, particularly in circles close to the organization, is that Hassan Nasrallah is still alive, and his silence is therefore a tool of "psychological warfare" against Israel. These circles particularly recall the July 2006 war, during which Hassan Nasrallah broke a three-day silence with a speech. He announced, live, a missile strike on an Israeli warship deployed in Lebanese waters. "Watch it burn," he exclaimed, in a speech forever etched in history.

A third hypothesis can be put forward: that the party is completely overwhelmed by events. If the death of its leader is confirmed, the entire command would have been decapitated. Hezbollah is probably awaiting instructions from its Iranian patron before reacting. But on Tehran's side too, there is radio silence.





Nasrallah led Hezbollah through decades of conflict with Israel

Updated / Saturday, 28 Sep 2024 
Hassan Nasrallah's most recent speech broadcast on 19 September

Lebanon's Sayyed Hassan Nasrallah, who Israel said it has killed, led Hezbollah through decades of conflict with Israel, overseeing its transformation into a military force with regional sway and becoming one of the most prominent Arab figures in generations - with Iranian backing.

The Iran-backed Hezbollah has yet to issue any statement on the status of Nasrallah, who led the group for 32 years.

The Israeli military said it had killed Nasrallah in an airstrike on the group's central headquarters in the southern suburbs of Beirut a day earlier.

The Israeli military "eliminated ... Hassan Nasrallah, leader of the Hezbollah terrorist organisation," Israeli army spokesperson Avichay Adraee wrote in a statement on X.

Among supporters, Nasrallah was lauded for standing up to Israel and defying the United States.

To enemies, he was head of a terrorist organisation and a proxy for Iran's Shi'ite Islamist theocracy in its tussle for influence in the Middle East.

His regional influence was on display over nearly a year of conflict ignited by the Gaza war, as Hezbollah entered the fray by firing on Israel from southern Lebanon in support of its Palestinian ally Hamas, and Yemeni and Iraqi groups followed suit, operating under the umbrella of "The Axis of Resistance".

"We are facing a great battle," Nasrallah said in an 1 August speech at the funeral of Hezbollah's top military commander, Fuad Shukr, who was killed in an Israeli strike on the Hezbollah-controlled southern suburbs of Beirut.

Yet when thousands of Hezbollah members were injured and dozens killed, when their communications devices exploded in an apparent Israeli attack last week, that battle began to turn against his group.

Responding to the attacks on Hezbollah's communications network in a 19 September speech, Nasrallah vowed to punish Israel.

"This is a reckoning that will come, its nature, its size, how and where? This is certainly what we will keep to ourselves and in the narrowest circle even within ourselves," he said.

He had not given a broadcast address since then.

Israel has meanwhile dramatically escalated its attacks, killing several senior Hezbollah commanders in targeted strikes and unleashing a massive bombardment in Hezbollah-controlled areas of Lebanon, which has killed hundreds of people.

Recognised even by his enemies as a skilled orator, Nasrallah's speeches were followed by friend and foe alike.

Wearing the black turban of a sayyed, or a descendent of the Prophet Mohammad, Nasrallah used his addresses to rally Hezbollah's base but also to deliver carefully calibrated threats, often wagging his finger as he does so.

He became secretary general of Hezbollah in 1992 aged just 35, the public face of a once shadowy group founded by Iran's Revolutionary Guards in 1982 to fight Israeli occupation forces.

Israel killed his predecessor, Sayyed Abbas al-Musawi, in a helicopter attack. Nasrallah led Hezbollah when its guerrillas finally drove Israeli forces from southern Lebanon in 2000, ending an 18-year occupation.

'Divine victory'

Conflict with Israel largely defined his leadership. He declared "Divine Victory" in 2006 after Hezbollah waged 34 days of war with Israel, winning the respect of many ordinary Arabs who had grown up watching Israel defeat their armies.

But he became an increasingly divisive figure in Lebanon and the wider Arab world as Hezbollah's area of operations widened to Syria and beyond, reflecting an intensifying conflict between Shi'ite Iran and US-allied Sunni Arab monarchies in the Gulf.

While Nasrallah painted Hezbollah's engagement in Syria - where it fought in support of President Bashar al-Assad during the civil war - as a campaign against jihadists, critics accused the group of becoming part of a regional sectarian conflict.

At home, Nasrallah's critics said Hezbollah's regional adventurism imposed an unbearable price on Lebanon, leading once friendly Gulf Arabs to shun the country - a factor that contributed to its 2019 financial collapse.

In the years following the 2006 war, Nasrallah walked a tightrope over a new conflict with Israel, hoarding Iranian rockets in a carefully measured contest of threat and counter threat.

The Gaza war, ignited by the 7 October Hamas attack on Israel, prompted Hezbollah's worst conflict with Israel since 2006, costing the group hundreds of its fighters including top commanders.

After years of entanglements elsewhere, the conflict put renewed focus on Hezbollah's historic struggle with Israel.

"We are here paying the price for our front of support for Gaza, and for the Palestinian people, and our adoption of the Palestinian cause," Nasrallah said in the 1 August speech.

Nasrallah grew up in Beirut's impoverished Karantina district. His family hail from Bazouriyeh, a village in the Lebanon's predominantly Shi'ite south which today forms Hezbollah's political heartland.

He was part of a generation of young Lebanese Shi'ites whose political outlook was shaped by Iran's 1979 Islamic Revolution.

Before leading the group, he used to spend nights with frontline guerrillas fighting Israel's occupying army. His teenage son, Hadi, died in battle in 1997, a loss that gave him legitimacy among his core Shi'ite constituency in Lebanon.

Hassan Nasrallah's son Hadi was killed in battle in 1997

Powerful enemies

He had a track record of threatening powerful enemies.

As regional tensions escalated after the eruption of the Gaza war, Nasrallah issued a thinly veiled warning to US warships in the Mediterranean, telling them: "We have prepared for the fleets with which you threaten us."

In 2020, Nasrallah vowed that US soldiers would leave the region in coffins after Iranian general Qassem Soleimani was killed in a US drone strike in Iraq.

He expressed fierce opposition to Saudi Arabia over its armed intervention in Yemen, where, with US and other allied support, Riyadh sought to roll back the Iran-aligned Houthis.

As regional tensions rose in 2019 following an attack on Saudi oil facilities, he said Saudi Arabia and the United Arab Emirates should halt the Yemen war to protect themselves.

"Don't bet on a war against Iran because they will destroy you," he said in a message directed at Riyadh.
On Nasrallah's watch, Hezbollah has also clashed with adversaries at home in Lebanon.

In 2008, he accused the Lebanese government - backed at the time by the West and Saudi Arabia - of declaring war by moving to ban his group's internal communication network. Nasrallah vowed to "cut off the hand" that tried to dismantle it.

It prompted four days of civil war pitting Hezbollah against Sunni and Druze fighters, and the Shi'ite group to take over half the capital Beirut.

He strongly denied any Hezbollah involvement in the 2005 assassination of former Prime Minister Rafik al-Hariri, after a UN-backed tribunal indicted four members of the group.

Nasrallah rejected the tribunal - which in 2020 eventually convicted three of them in absentia over the assassination - as a tool in the hands of Hezbollah's enemies.

 

Light at the end of the tunnel for night shift workers



Flinders University





The use of circadian-informed lighting, where artificial lighting is synchronised to the natural biological rhythms or a person’s ‘body-clock’, significantly improves quality of sleep and work performance for night shift workers, a major new trial has found.

The Flinders University trial is amongst the first tightly controlled in-laboratory studies to have simultaneously evaluated circadian-lighting effects on markers of body-clock timing, work-shift cognitive performance, and sleep following an abrupt transition to night shift work.

The results of the trial have produced two papers published in the prestigious Oxford University Press SLEEP journal, finding that strategic exposure to light accelerated body-clock adjustment and improved alertness and performance, as well as sleep after a night shift.

“Circadian rhythms reflect our body’s internal clocks that control the activity and timing of bodily functions, including our sleep-wake cycle,” says Flinders University sleep researcher Dr Hannah Scott, author of Circadian-informed lighting improves vigilance, sleep, and subjective sleepiness during simulated night shift work.

“Shift work causes circadian disruption, for which well-timed light exposure, designed to promote alertness and facilitate circadian adjustment, is one of the most potent methods to help retime the body clock.”

In Australia, around 15-16 per cent of Australian workers report being shift workers. For both men and women, rotating shifts with varying schedules each week are the most prevalent type of shift work.

Supported by the Defence Science and Technology Group through the Research Network for Undersea Decision Superiority, the findings will be of particular interest for shift workers in enclosed environments such as submarines where lighting is typically dim.

“Given the complete lack of normal day-night lighting, shift work on submarines maybe be particularly challenging for the body clock to adjust to,” says Dr Scott.

“We wanted to explore the unique challenges posed by night shifts, particularly the disruption to sleep-wake schedules, which can lead to impaired mental and physical performance, poorer sleep and health issues.

“We found that the use of circadian-informed lighting promoted better improved job performance and sleep for those working irregular hours,” says Dr Scott.

19 adults participated in the study, which took place in FHMRI Sleep Health’s laboratory under tightly controlled conditions that simulated night work environments.

Participants were exposed to two different lighting scenarios for a period of eight days to compare how their body clock adjusted and how they performed in a series of tasks.

The circadian-informed lighting, consisted of blue-enriched and dim, blue-depleted conditions designed to help the body clock adjust to night work, whilst the traditional dim, blue-depleted lighting simulated the standard lighting conditions onboard submarines.

The research team then assessed key circadian measures including melatonin levels and core body temperature, along with other outcomes including cognitive performance and sleep.

Importantly, over four consecutive simulated night shifts, the circadian informed lighting shifted participants’ body-clocks around one hour faster per day compared to the standard lighting.

Alisha Guyett, lead author of A circadian-informed lighting intervention accelerates circadian adjustment to a night work schedule in a submarine lighting environment says that the findings are very promising for night shift employers and employees.

“The overarching benefits of circadian-informed lighting on sleep and alertness are very clear from this study. Our findings suggest that strategic lighting interventions can likely be used to enhance the performance, sleep, safety and well-being of night shift workers exposed to inadequate light during their work shift,” says Ms Guyett.

“The circadian-informed lighting interventions significantly accelerated participants' adjustment to night work, which could have important implications for improving the health and performance of those who regularly work night shifts.”

Notably, after circadian-informed lighting, participants achieved almost one hour more of sleep compared to the standard lighting condition as well as reporting lower levels of sleepiness during their shifts.

To test alertness, participants in both lighting conditions were subjected to the Psychomotor Vigilance Task (PVT) test, a behavioural attention measure. Those in circadian-informed lighting conditions made half as many (7.4 lapses) mistakes as those in standard lighting (15.6 lapses).

Senior Flinders Health and Medical Research Institute: Sleep Health researcher Professor Peter Catcheside says: “This study highlights the importance of the circadian system and circadian friendly lighting to help alleviate some of the significant challenges of shift work.

“It adds to what we already know about the use of these interventions to help optimise workspaces for enhanced performance, safety, and well-being in the modern workforce.

“These findings have important implications for submariner lighting conditions, but also mining and other workplace environments where lighting conditions may make it more difficult for shift workers to successfully adjust their body-clocks to the work schedule,” he adds.

WASHINGTON, D.C. — Sept.  26, 2024 — Most Americans agree their community is in need of more affordable housing, healthcare and social supports and services to help residents remain living independently as they age, according to a new survey from West Health and Gallup. Sixty-five percent of Americans perceive a need for more affordable housing and 60% say there is a need for more affordable healthcare and social supports and services.

The new West Health-Gallup research comes as the federal government, community leaders and advocates, nonprofits and other stakeholders work to develop a National Plan on Aging, a set of age-friendly practice and policy recommendations for addressing the growing needs of America’s aging population over the next decade, which according to previous research, most Americans (66%) do not believe the country is ready to handle. By 2030, older adults will make up nearly 21% of the population and, for the first time in U.S. history, outnumber people under 18.

“America is facing a profound demographic shift that requires new thinking and smart planning that cuts across multiple sectors from housing and healthcare to transportation and social services,” said Timothy A. Lash, President, West Health, a nonprofit focused on healthcare and aging. “This survey shows Americans sense the need, and now policy makers need to sense the urgency and develop plans that better reflect an older America.” 

In addition to medical care and housing, the survey found one in five adults perceive a “major need” for more mental health services (22%), which just 16% say they find “very easy” to access in their communities. While men and women report roughly the same sense of ease of access, women are nearly twice as likely as men to say their community has a major need for mental health services (28% vs. 16%, respectively). Conversely, nearly a third of respondents (32%) say it is very easy to access physical healthcare, and only 16% say more is a major need in their communities.

“These findings demonstrate the American public is well aware of the need to be better prepared as the population ages,” said Dan Witters, senior researcher at Gallup. “Now it’s a question of what policymakers and other stakeholders will do to address the need and the urgency.”

Methodology

The West Health-Gallup Survey was conducted by web June 3 to June 18, 2024, with a 2,180 representative sample of U.S. adults aged 18 and older, living in all 50 U.S. states and the District of Columbia as a part of the Gallup Panela probability based panel of about 100,000 adults nationwide.

Fluoride-free batteries: Safeguarding the environment and enhancing performance

A research team led by Professor Soojin Park and Seoha Nam from the Department of Chemistry at POSTECH, in partnership with Hansol Chemical’s Battery materials R&D center, has developed a new fluorine-free binder and electrolyte designed to advance eco-friendly, high-performance battery technology. Their findings were recently published in “Chemical Engineering Journal”, an international journal in the field of chemistry.

 

As environmental concerns intensify, the importance of sustainable materials in battery technology is growing. Traditional lithium batteries rely on fluorinated compounds such as polyvinylidene fluoride (PVDF) binders and lithium hexafluorophosphate (LiPF6, LP) salts. However, this "PVDF-LP" system releases highly toxic hydrogen fluoride (HF), which reduces battery performance and lifespan. Furthermore, PVDF is non-biodegradable, and with the European Union (EU) tightening regulations on PFAS, a ban on these substances is expected by 2026.

 

Researchers from POSTECH and Hansol Chemical have designed a non-fluorinated battery system to comply with upcoming environmental regulations and enhance battery performance. They created a lithium perchlorate (LiClO4, LC)-based electrolyte to replace fluorinated LP electrolytes along with a non-fluorinated aromatic polyamide (APA) binder using Hansol Chemical’s proprietary technology. This innovative “APA-LC” system is entirely free of fluorinated compounds.

 

The “APA binder” reinforces the bonding between the cathode's active material and the aluminum current collector, preventing electrode corrosion in the electrolyte and significantly extending battery life. Additionally, the “LC system,” enriched with lithium chloride (LiCl) and lithium oxide (Li2O), lowers the energy barrier at the interface to promote ion migration, leading to faster lithium diffusion and superior output performance compared to the existing LP system. Overall, the APA-LC system exhibited greater oxidation stability than the conventional PVDF-LP system and maintained 20% higher capacity retention after 200 cycles at a rapid charge/discharge rate of 1 C, within the 2.8–4.3 V range in a coin cell test.

 

The research team applied the APA-LC system to produce a high-capacity 1.5 Ah (ampere-hour) pouch cell. The cell maintained excellent discharge capacity and demonstrated strong performance during fast-charging trials. This marks the world's first successful demonstration of a battery system that is entirely scalable and practical, made entirely from non-fluorinated materials, without any fluorinated compounds.

 

Professor Soojin Park of POSTECH expressed the significance of the research by saying, "We haven’t just replaced fluorinated systems; we’ve proven high-capacity retention and outstanding stability." He continued, "Our solution will advance the sustainability of the battery industry, facilitating the shift to non-fluorinated battery systems while ensuring environmental compliance." 

 

Managing Director Young-Ho Yoon of Hansol Chemical's Secondary Battery Materials Business remarked, “By addressing PFAS regulatory concerns, we’ve secured a foothold in the global cathode binder market, projected to reach KRW 1.7 trillion by 2026.” He added, “Continued research will solidify our position as a leading supplier of eco-friendly secondary battery materials.”

This collage highlights a small selection of regions of the Milky Way imaged as part of the most detailed infrared map ever of our galaxy. Here we see, from left to right and top to bottom: NGC 3576, NGC 6357, Messier 17, NGC 6188, Messier 22 and NGC 3603. All of them are clouds of gas and dust where stars are forming, except Messier 22, which is a very dense group of old stars.

The images were captured with ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA) and its infrared camera VIRCAM. The gigantic map to which these images belong contains 1.5 billion objects. The data were gathered over the course of 13 years as part of the VISTA Variables in the Vía Láctea (VVV) survey and its companion project, the VVV eXtended survey (VVVX).

Astronomers have published a gigantic infrared map of the Milky Way containing more than 1.5 billion objects ― the most detailed one ever made. Using the European Southern Observatory’s VISTA telescope, the team monitored the central regions of our Galaxy over more than 13 years. At 500 terabytes of data, this is the largest observational project ever carried out with an ESO telescope.

We made so many discoveries, we have changed the view of our Galaxy forever,” says Dante Minniti, an astrophysicist at Universidad Andrés Bello in Chile who led the overall project.

This record-breaking map comprises 200 000 images taken by ESO’s VISTA ― the Visible and Infrared Survey Telescope for Astronomy. Located at ESO’s Paranal Observatory in Chile, the telescope’s main purpose is to map large areas of the sky. The team used VISTA’s infrared camera VIRCAM, which can peer through the dust and gas that permeates our galaxy. It is therefore able to see the radiation from the Milky Way’s most hidden places, opening a unique window onto our galactic surroundings.

This gigantic dataset [1] covers an area of the sky equivalent to 8600 full moons, and contains about 10 times more objects than a previous map released by the same team back in 2012. It includes newborn stars, which are often embedded in dusty cocoons, and globular clusters –– dense groups of millions of the oldest stars in the Milky Way. Observing infrared light means VISTA can also spot very cold objects, which glow at these wavelengths, like brown dwarfs (‘failed’ stars that do not have sustained nuclear fusion) or free-floating planets that don’t orbit a star.

The observations began in 2010 and ended in the first half of 2023, spanning a total of 420 nights. By observing each patch of the sky many times, the team was able to not only determine the locations of these objects, but also track how they move and whether their brightness changes. They charted stars whose luminosity changes periodically that can be used as cosmic rulers for measuring distances [2]. This has given us an accurate 3D view of the inner regions of the Milky Way, which were previously hidden by dust. The researchers also tracked hypervelocity stars — fast-moving stars catapulted from the central region of the Milky Way after a close encounter with the supermassive black hole lurking there.

The new map contains data gathered as part of the VISTA Variables in the Vía Láctea (VVV) survey [3] and its companion project, the VVV eXtended (VVVX) survey. “The project was a monumental effort, made possible because we were surrounded by a great team,” says Roberto Saito, an astrophysicist at the Universidade Federal de Santa Catarina in Brazil and lead author of the paper published today in Astronomy & Astrophysics on the completion of the project.

The VVV and VVVX surveys have already led to more than 300 scientific articles. With the surveys now complete, the scientific exploration of the gathered data will continue for decades to come. Meanwhile, ESO’s Paranal Observatory is being prepared for the future: VISTA will be updated with its new instrument 4MOST and ESO's Very Large Telescope (VLT) will receive its MOONS instrument. Together, they will provide spectra of millions of the objects surveyed here, with countless discoveries to be expected.

Notes

[1] The dataset is too large to release as a single image, but the processed data and objects catalogue can be accessed in the ESO Science Portal.

[2] One way to measure the distance to a star is by comparing how bright it appears as seen from Earth to how intrinsically bright it is; but the latter is often unknown. Certain types of stars change their brightness periodically, and there is a very strong connection between how quickly they do this and how intrinsically luminous they are. Measuring these fluctuations allows astronomers to work out how luminous these stars are, and therefore how far away they lie. 

[3] Vía Láctea is the Latin name for the Milky Way.

The European Southern Observatory (ESO) enables scientists worldwide to discover the secrets of the Universe for the benefit of all. We design, build and operate world-class observatories on the ground — which astronomers use to tackle exciting questions and spread the fascination of astronomy — and promote international collaboration for astronomy. Established as an intergovernmental organisation in 1962, today ESO is supported by 16 Member States (Austria, Belgium, Czechia, Denmark, France, Finland, Germany, Ireland, Italy, the Netherlands, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom), along with the host state of Chile and with Australia as a Strategic Partner. ESO’s headquarters and its visitor centre and planetarium, the ESO Supernova, are located close to Munich in Germany, while the Chilean Atacama Desert, a marvellous place with unique conditions to observe the sky, hosts our telescopes. ESO operates three observing sites: La Silla, Paranal and Chajnantor. At Paranal, ESO operates the Very Large Telescope and its Very Large Telescope Interferometer, as well as survey telescopes such as VISTA. Also at Paranal ESO will host and operate the Cherenkov Telescope Array South, the world’s largest and most sensitive gamma-ray observatory. Together with international partners, ESO operates ALMA on Chajnantor, a facility that observes the skies in the millimetre and submillimetre range. At Cerro Armazones, near Paranal, we are building “the world’s biggest eye on the sky” — ESO’s Extremely Large Telescope. From our offices in Santiago, Chile we support our operations in the country and engage with Chilean partners and society.

A Chinese team of scientists has undertaken a study of lunar samples retrieved by the Chang'E-6 mission. These are the first samples studied from the farside of the Moon. They mark a significant milestone in lunar exploration science and technical exploration capability. The study was published in the journal National Science Review on September 17, 2024.

"As the first lunar sample obtained from the far side of the Moon, the Chang'E-6 sample will provide an unparalleled opportunity for lunar research," said Prof. Chunlai Li, National Astronomical Observatories of the Chinese Academy of Sciences. This unique sample helps to advance the understanding of several key aspects of lunar science, including the Moon's early evolution; the variability of volcanic activities between the nearside and farside; the impact history of the inner solar system; the record of galactic activity preserved in the lunar weathering layer; the lunar magnetic field and its anomalies and duration; and the composition and structure of the lunar crust and mantle. "These insights are expected to lead to new concepts and theories regarding the origin and evolution of the Moon, and refine its use as an interpretive paradigm for the evolution of the terrestrial planets," said Li.

Adding together the lunar samples gathered from the six Apollo missions, three Luna missions, and the Chang'E-5 mission, scientists have collected a total of 382.9812 kg of lunar samples. These lunar samples have provided scientists with critical information on the formation and evolutionary history of the Moon. "Returned lunar samples are essential to planetary science research, as they provide key laboratory data to link orbital remote sensing observations to actual surface ground truth," said Li. The samples have contributed to the development of hypotheses, such as the Moon's giant impact into early Earth origin, the Lunar Magma Ocean, and the Late Heavy Bombardment. These earlier studies of lunar samples, all of them collected from the lunar nearside, have significantly advanced the discipline of planetary science. From a sampling perspective, the farside has remained unexplored until now.

"Nearside samples alone, without adequate sampling from the entire lunar surface, especially from the farside, cannot fully capture the geologic diversity of the entire Moon. This limitation hampers our understanding of the Moon's origin and evolution," said Li. Scientists gained the much-needed farside lunar samples when the Chang'E-6 mission collected 1935.3 grams of lunar samples from the South Pole-Aitken basin on June 25, 2024.

The samples were gathered from the lunar surface using drilling and scooping techniques. The team analyzed the samples' physical, mineralogical, petrographic, and geochemical properties. Their analysis showed that the collected samples reflect a mixture of "local" basaltic material and "foreign" non-mare material. The rock fragments in the Chang'E-6 samples are mainly basalt, breccia, and agglutinates. The primary constituent minerals of the soils are plagioclase, pyroxene, and ilmenite, with very low olivine abundance. The lunar soil in the Chang'E-6 samples is mostly a mixture of local basalts and non-basaltic ejecta materials.

The lunar surface is divided into three very distinct geochemical provinces based on variations in geochemical characterization and petrologic evolutionary history. These are the Procellarum KREEP Terrane (PKT), the Feldspathic Highland Terrane (FHT), and the South Pole-Aitken Terrane (SPAT).

"These local mare basalts document the volcanic history of lunar farside, while the non-basaltic fragments may offer critical insights into the lunar highland crust, South Pole-Aitken impact melts, and potentially the deep lunar mantle, making these samples highly significant for scientific research," said Li.

The lunar samples collected from the nearside by the Apollo, Luna, and Chang'E-5 missions included samples from the PKT and the FHT. Until now, no samples had been collected from the unique SPAT on the lunar farside. Scientists believe the South Pole-Aitken basin was formed 4.2 to 4.3 billion years ago in the Pre-Nectarian period. It is the largest confirmed impact basin in the Solar System.

The research is funded by the Key Research Program of the Chinese Academy of Sciences.
