  • ERC – European stars aim to ace the Rome asphalt

    ERC – European stars aim to ace the Rome asphalt

    It’s Tarmac time in the FIA European Rally Championship once again after three action-packed gravel counters.

    As well as a change of surface, Rally di Roma Capitale marks the start of the second half of the season, which has celebrated four different winners from the opening four rounds.

    Ever-present on the ERC schedule since 2017, when Bryan Bouffier beat Kajetan Kajetanowicz by 0.3sec in the closest finish of the modern European championship era, Rally di Roma begins on Friday (4 July) with a spectacular driving parade through the Eternal City.

    That’s followed by a 1.3-kilometre super special stage in front of the Colosseum, one of the Seven Wonders of the World, as the sun begins to set, prior to two days of fast-paced asphalt competition around host town Fiuggi, south of Rome.

    “The roads are completely different from day one and day two,” said Andrea Mabellini, Italy’s top ERC driver, who competes in a Škoda Fabia RS Rally2 on Pirelli tyres. “Day one is a little more bumpy, the second day is more clean so we must find a compromise with the set-up or two different set-ups that work between two days. It’s going to be one of the toughest races in terms of being at the right speed and we must consider the drivers from the Italian championship.”

    Mabellini continued: “There are two long stages and for sure the organiser makes the challenge even higher than in the previous years and the temperatures will be very hot, even if it is earlier in July than last year.”

    Massive entry for a monumental challenge
    An unprecedented 85 crews have registered for FIA European Rally Championship points on Rally di Roma Capitale to underline the huge interest in the ERC and the Italian event. A season-high 38 drivers will compete in the headlining ERC1 category for Rally2 cars. In addition, 11 drivers have entered the Rally3-based ERC3, while 36 drivers are eligible for ERC4, which caters for Rally4 and Rally5 machinery. Of those 36, 16 will be in contention for honours in the Hankook-equipped FIA Junior ERC Championship with 18 competing in the new-for-2025 Lancia Ypsilon Rally4 HF. Eight drivers will chase the various incentives on offer in the ERC Fiesta Rally3 Trophy.

    Marczyk tops the ERC title order
    Michelin-equipped Miko Marczyk heads to Italy for Rally di Roma Capitale with a 16-point advantage over fellow Michelin runner Mads Østberg in the race to become ERC champion for 2025. Pirelli-supplied Tymek Abramowski tops the ERC3 and ERC Fiesta Rally3 Trophy standings, while Dariusz Biedrzyński, another Pirelli contender, leads the Master ERC ranking. Hankook-shod Calle Carlberg heads the order in ERC4 and Junior ERC followed by Victor Hansen and Ioan Lloyd respectively. Team MRF Tyres is first in the FIA European Rally Championship for Teams with Michelin ahead in the FIA European Rally Championship for Tyre Suppliers.

    Rally di Roma Capitale route in short
    Event organiser Motorsport Italia has prepared an itinerary featuring three all-new special stages and a “complete route revision” following the return of legendary stages from previous editions of the asphalt-only event. It has stated with confidence that “the revamped layout raises the bar for competition and spectacle alike”.

    Following Friday evening’s Colosseum super special, leg one on Saturday consists of three stages run either side of service in Fiuggi. At 34.57 kilometres, the double use Torre di Cicerone is the rally’s longest stage. Sunday’s leg follow an identical format with a midday service stop in Fiuggi taking place following a trio of stages that are repeated in the afternoon. Canterano – Subiaco is the longest of the day at 30.59 kilometres, while the Jenne – Monastero Power Stage is scheduled to get under way at 17:05 local time.

    Collepardo Pozzo d’Antullo, Torre di Cicerone and Jenne – Monastero are new stages for 2025.

  • Oasis kick off reunion tour in Cardiff with triumphant, nostalgic gig – The Irish Times

    Oasis kick off reunion tour in Cardiff with triumphant, nostalgic gig – The Irish Times

    Swaggering, cocksure and incredibly loud, Oasis burst back on to the live music scene on Friday night with an accomplished – if ever so slightly distanced – debut gig on their reunion world tour.

    Playing Cardiff’s Principality Stadium, the six-piece impressed at the start of what is arguably the most anticipated tour of the century, focusing overwhelmingly on songs from their 1990s heyday – only one song, Little By Little, was taken from their final four albums.

    For years it looked as if Liam and Noel Gallagher would never patch up their fractious fraternal relationship. A backstage bust-up in 2009 brought Oasis to an end, after a 16-year career in which they became the pre-eminent British rock’n’roll band, and the Gallaghers continued to snipe at each other in the press and social media in the following years – most memorably with Liam dubbing Noel a “potato”. Even when Oasis announced a reunion in August 2024 – “The guns have fallen silent. The stars have aligned. The great wait is over” – some fans wondered if another ruction between the brothers would scupper the plans.

    But following support slots from Britpop peers Cast and Richard Ashcroft, Oasis did indeed appear. They kicked straight into gear without a word to the crowd, playing Hello, the song that begins (What’s the Story) Morning Glory?, their 18-times platinum album which is outsold in the UK only by Queen and Abba’s greatest hits.

    “Because we need each other, we believe in one another”, Noel Gallagher sang on the second track, Acquiesce: a statement of unity that inspired delirious mosh pits and crowd-surfing. But the actual relations between the Gallaghers were relatively frosty, with little acknowledgment of each other, and with original guitarist Paul “Bonehead” Arthurs stationed between them.

    The Gallaghers were backed by Arthurs, the rhythm guitarist on their era-defining first two albums Definitely Maybe (1994) and (What’s the Story) Morning Glory (1995), plus 1997 follow-up Be Here Now, which was less critically acclaimed but still enormous in terms of sound and commercial success. More recently, Arthurs had played with Liam Gallagher’s solo band.

    Arthurs, who was successfully treated for tonsil cancer in 2022, was replaced in Oasis in 1999 by Gem Archer, who also features in the new line-up having played with both Liam and Noel during their solo careers. Andy Bell, the co-founder of Ride – Oasis’s label mates on Creation Records – and another 1999 Oasis appointee, played bass. The American musician Joey Waronker, known for his work with Beck, REM and Radiohead’s Thom Yorke, was on drums, having recently collaborated with Liam Gallagher on his 2024 album with Stone Roses guitarist John Squire.

    Noel took the lead on a three-song run of Talk Tonight, Half the World Away and Little By Little – the only post-millennium song, from 2002’s Heathen Chemisty – in the middle of the set, with Liam bringing his trademark sneer and brio back for D’You Know What I Mean, which led into another Be Here Now song, Stand By Me.

    Thereafter it was a return to the middle of the mid-1990s, with one-off singles and B-sides such as Whatever and The Masterplan, and a run of the band’s very biggest hits including Live Forever, Rock ’n’ Roll Star, Don’t Look Back in Anger, Wonderwall and Champagne Supernova.

    The latter-day Oasis albums aren’t as well loved as the first three, but they certainly contain songs fans might have expected to hear including Stop Crying Your Heart Out, Lyla, Songbird and Go Let it Out. There were no curveballs or deep cuts. Instead, Oasis delivered exactly what most fans were hoping for.

    There were tributes to the late Portuguese footballer Diego Jota, who died yesterday in a car crash at the age of 28: he was well known to British fans, having won the Premier League and FA Cup during a spell with Liverpool. Cast dedicated their own football anthem, Walkaway to him, and an image of Jota was displayed during Oasis’s performance of Live Forever.

    For a famously gobby band, there was relatively little stage banter, though Liam beseeched the crowd at one point: “I want you to turn around and put your arms around each other … and jump up and fucking down.”

    He also made a brazen reference to the pricing scandal that made headlines when tickets went on sale: a “dynamic pricing” mechanism meant that the popularity of the tickets drove up the cost, prompting anger from fans and promises from culture secretary Lisa Nandy to look into the practice. “What’s happening? Everyone having a good time yeah? Is it worth the £4,000 you paid for a ticket?”, Liam told the crowd.

    Noel meanwhile thanked the band’s younger fans as he began the encore with a rendition of The Masterplan: “This one is for all the people in their 20s who have never seen us before who have kept us shit hot for the last 20 years.” – Guardian service

  • Hamas submits ‘positive response’ to ceasefire proposal in major step toward a deal

    Hamas submits ‘positive response’ to ceasefire proposal in major step toward a deal



    CNN
     — 

    Hamas announced on Friday that it had “submitted a positive response” to a proposal for a 60-day ceasefire with Israel in Gaza, opening the path toward a deal to halt the conflict after months of failed efforts.

    Hamas has “submitted a positive response to the mediators, and the movement is fully prepared to immediately enter into a round of negotiations regarding the mechanism for implementing this framework,” the group said in a statement.

    Israel had previously accepted the US-sponsored framework, which means the two sides are now expected to enter final, detailed negotiations before a ceasefire agreement is officially reached.

    Bishara Bahbah, a Palestinian-American interlocutor who has been in direct discussions with Hamas, praised the group’s response on Facebook, saying, “We are now much closer to ending this cursed war.”

    He said Hamas had introduced “amendments it deemed necessary.”

    “In my view, these amendments will not prevent reaching a ceasefire agreement within the coming week, God willing,” he said.

    An Israeli source familiar with the matter said earlier Friday that Israel had expected a positive response from Hamas, with the rewording of a few points in the proposal language. The source said these changes were not expected to derail the ceasefire efforts.

    Of the 50 Israeli hostages remaining in Gaza, the proposal calls for the release of 10 living hostages and 18 deceased during the ceasefire. On the first day of the ceasefire, Hamas would release eight living hostages in exchange for an unspecified number of Palestinian prisoners and detainees. Following the release, Israel would withdraw from parts of northern Gaza, and the two sides would begin negotiations toward a permanent ceasefire.

    The release of the hostages is to take place without any Hamas ceremonies or fanfare. The remaining hostages would be released on four more dates specific in the proposal.

    Efforts to secure a ceasefire intensified following the 12-day conflict between Israel and Iran last month. Qatar, a key negotiator, immediately launched a new round of indirect talks between Israel and Hamas to find a “middle ground” based on previous proposals.

    The new proposal includes stronger assurances about the US’s commitment to keeping Israel at the negotiating table to reach a permanent ceasefire deal, during or potentially after the 60-day truce, according to an Israeli official and source familiar with the negotiations.

    It also commits Israel to allowing a surge of aid into Gaza through traditional humanitarian channels, rather than through the controversial Israeli-backed Gaza Humanitarian Foundation.

    US President Donald Trump has pushed hard for a ceasefire, saying on Tuesday that Israel had “agreed to the necessary conditions” to finalize a deal for a 60-day cessation of hostilities. In a post on Truth Social, Trump warned Hamas to accept the proposal as well.

    “I hope, for the good of the Middle East, that Hamas takes this Deal, because it will not get better — IT WILL ONLY GET WORSE,” he said, thanking Qatar and Egypt for their role in advancing the proposal.

    Israel accepted the new proposal on Tuesday while Ron Dermer, a confidant of Prime Minister Benjamin Netanyahu, was in Washington, DC, meeting with top Trump administration officials, including US special envoy Steve Witkoff. The next day, Hamas said it was discussing the proposal as part of “national consultations” and that it aimed to reach an agreement that would guarantee “an end to the aggression, the withdrawal (of Israeli forces), and urgent relief for our people in the Gaza Strip.”

    According to a source familiar with the negotiations, Israel and Hamas are now expected to enter quickly into proximity talks, during which officials from both sides are in the same building, with negotiators passing messages between them expeditiously to reach a deal. Such talks can take days, or they can be concluded faster. One of the key issues to resolve will be the timeline for the withdrawal of Israeli forces in Gaza during the ceasefire, the source said.

    Qatar submitted the new proposal for a 60-day ceasefire, backed by the Trump administration, to both Hamas and Israel this week, following months of behind-the-scenes efforts led by Witkoff.

    After a two-month ceasefire collapsed in March – and Israel renewed its bombardment of Gaza – the Trump administration put forward a ceasefire proposal that was rejected by Hamas because it failed to include guarantees about a permanent end to the war. The new version attempted to account for that key Hamas demand, offering stronger US assurances that the ceasefire would continue beyond 60 days even if a comprehensive agreement had not yet been reached.

    Injured Palestinians are brought to al-Ahli Baptist Hospital to receive medical treatment after an Israeli airstrike in the Gaza Strip on July 4, 2025.

    Israel has killed more than 57,000 Palestinians in Gaza since the war began, according to the Palestinian Ministry of Health. As negotiators worked to advance the latest ceasefire proposal, Israel intensified its bombardment of Gaza, killing scores across the besieged enclave.

    Until now, Israel has refused to agree to a ceasefire deal that includes a comprehensive end to the war, as Netanyahu said the country’s goals included destroying Hamas’ military capability and ability to govern. But after the conflict with Iran, he has signaled a new willingness to compromise.

    On Sunday, Netanyahu said that “many opportunities have opened up” following Israel’s military operations in Iran, including the possibility of bringing home the remaining hostages held in Gaza. It marked the first time in months that the long-time Israeli leader has clearly prioritized the return of the hostages over the defeat of Hamas.

    Netanyahu is scheduled to travel to Washington this weekend and meet Trump at the White House on Monday. Before he leaves for the trip, he will convene his full cabinet on Saturday night to discuss the proposal. Even though far-right members of Israel’s government have said they will try to torpedo the deal, other political parties have made clear they will throw their support behind a ceasefire.

    This is a developing story and will be updated.

  • Astronomers Track Interstellar Comet 3I/ATLAS

    Astronomers Track Interstellar Comet 3I/ATLAS

    3I/ATLAS is only the third object of its kind ever observed, following the interstellar asteroid 1I/ʻOumuamua in 2017 and the interstellar comet 2I/Borisov in 2019.

    The discovery image of 3I/ATLAS from the ATLAS telescope. Image credit: University of Hawai’i.

    3I/ATLAS is currently around 670 million km (420 million miles) from the Sun and will make its closest approach in October 2025, passing just inside the orbit of Mars.

    It is thought to be up to 20 km (12 miles) in diameter and is traveling roughly 60 km per second (37 miles per second) relative to the Sun.

    It poses no danger to Earth, coming no closer than 240 million km (150 million miles) — over 1.5 times the distance between Earth and the Sun.

    3I/ATLAS is an active comet; if it heats up sufficiently as it nears the Sun, it could begin to sublimate — a process in which frozen gases transform directly into vapor, carrying dust and ice particles into space to form a glowing coma and tail.

    However, by the time the comet reaches its closest point to Earth, it will be hidden behind the Sun. It is expected to reappear by early December 2025, offering astronomers another window for study.

    “Spotting a possible interstellar object is incredibly rare, and it’s exciting that our Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope caught it,” said Professor John Tonry, an astronomer at the University of Hawai’i.

    “These interstellar visitors provide an extremely interesting glimpse of things from solar systems other than our own.”

    “Quite a few come through our inner Solar System each year, although 3I/ATLAS is by far the biggest to date.”

    “The chances of one actually hitting the Earth are infinitesimal, less than 1 in 10 million each year, but ATLAS is continually searching the sky for any object that might pose a problem.”

    Astronomers are using telescopes in Hawai’i, Chile, and other countries to monitor the comet’s progress.

    They are interested in learning more about this interstellar visitor’s composition and behavior.

    “What makes interstellar objects like 3I/ATLAS so extraordinary is their absolutely foreign nature,” ESA astronomers said in a statement.

    “While every planet, moon, asteroid, comet and lifeform that formed in our Solar System shares a common origin, a common heritage, interstellar visitors are true outsiders.”

    “They are remnants of other planetary systems, carrying with them clues about the formation of worlds far beyond our own.”

    “It may be thousands of years until humans visit a planet in another solar system and interstellar comets offer the tantalizing opportunity for us to touch something truly otherworldly.”

    “These icy wanderers offer a rare, tangible connection to the broader galaxy — to materials formed in environments entirely unlike our own.”

    “To visit one would be to connect humankind with the Universe on a far greater scale.”

  • Ex-Arsenal footballer Thomas Partey charged with rape

    Ex-Arsenal footballer Thomas Partey charged with rape

    Former Arsenal footballer Thomas Partey has been charged with five counts of rape and one count of sexual assault.

    The offences are reported to have taken place between 2021-2022, the Metropolitan Police said.

    The charges involve three women, with two counts of rape relating to one woman, three counts of rape in connection to a second woman and one count of sexual assault linked to a third woman.

    The Ghanaian international denies the charges and “welcomes the opportunity to finally clear his name”, his lawyer said.

    The charges follow an investigation by detectives, which started in February 2022 after police first received a report of rape.

    The 32-year-old’s contract with Arsenal ended on Monday after playing with the team since 2020.

    An Arsenal spokesman said: “The player’s contract ended on June 30. Due to ongoing legal proceedings the club is unable to comment on the case.”

    The Football Association and the Premier League declined to comment.

    Det Supt Andy Furphy, who is leading the investigation, said: “Our priority remains providing support to the women who have come forward.

    “We would ask anyone who has been impacted by this case, or anyone who has information, to speak with our team. You can contact detectives about this investigation by emailing CIT@met.police.uk”

    Mr Partey, of Hertfordshire, is expected to appear at Westminster Magistrates’ Court on Tuesday 5 August.

    In a statement, his lawyer Jenny Wiltshire said: “Thomas Partey denies all the charges against him.

    “He has fully cooperated with the police and CPS throughout their three-year investigation.

    “He now welcomes the opportunity to finally clear his name.

    “Given that there are now ongoing legal proceedings, my client is unable to comment further.”

    Mr Partey joined Arsenal for £45.3m from Atletico Madrid in October 2020, made 35 top-flight appearances last season and scored four goals as the London club finished second in the Premier League.

    He also played 12 times in the Champions League as the Gunners reached the semi-finals before being knocked out by eventual winners Paris St-Germain.

    Overall, he made 130 Premier League appearances for Mikel Arteta’s side, scoring nine goals.

    Mr Partey has also made more than 50 appearances for Ghana’s national team, and most recently played at World Cup qualification matches in March.

  • Why is Iran doubling down on its nuclear program? – DW – 07/04/2025

    Why is Iran doubling down on its nuclear program? – DW – 07/04/2025

    Tehran is officially halting its collaboration with the International Atomic Energy Agency (IAEA) in the wake of the recent US and Israeli air strikes.

    “As long as the security of Iranian nuclear facilities is not ensured, Iran will suspend its cooperation with the IAEA,”  parliamentary speaker Mohammad Bagher Ghalibaf said on state television last week, with President Masoud Pezeshkian signing off on the move this Wednesday.

    The specifics of the measure, however, remain unclear.

    For example, it is not yet known how it would affect the IAEA inspectors that remained in Iran throughout the 12-day conflict. 

    The Vienna-based UN agency hopes to gain more information on the state of the three of Iran’s top nuclear facilities — in Fordo, Isfahan and Natanz — which were targeted by the US-Israeli bombing.

    It also unclear if Iran is willing to remain in the Non-Proliferation Treaty (NPT), the cornerstone of global arms control, after its facilities were hit.

    “The fact that these facilities were attacked while under (IAEA) safeguards, while there is no evidence that they were being used for weaponization, is stirring the debate in Iran about whether the NPT still provides security value,” Kelsey Davenport, the Director for Nonproliferation Policy at the Arms Control Association think tank, told DW.

    Ahead of the Israeli strikes on Iran, the IAEA warned that Iran was the only nation without nuclear arms that is enriching uranium at nearly weapons-grade levels and that it had enough material for several nuclear bombs. At the same time, however, the IAEA stressed it did not have “any proof of a systematic effort to move into a nuclear weapon.”

    Iran halts cooperation with UN nuclear watchdog

    US helped Iran launch nuclear program 

    Tehran’s nuclear program has a long and complicated history going back to the 1950s and Shah Mohammad Reza Pahlavi.

    The US-backed monarch decided to join an initiative launched by US President Dwight D. Eisenhower known as “Atoms for Peace,” which aimed to give other nations — especially developing ones — access to civilian nuclear technology. Iran took advantage of the offer to build the foundations of its own nuclear program.

    Tehran also joined the IAEA in 1958, just a year after the UN agency was founded in Vienna.

    The nuclear program was seen as a prestige project in Iran. The country wanted to boost its production of electricity and eventually produce its own nuclear fuel independently of foreign suppliers while also reducing the consumption of oil and gas.

    In 1970, Iran signed the Non-Proliferation Treaty, which allows for civilian use of nuclear energy under the IAEA supervision.

    After the revolution

    The Islamist Revolution of 1979 left Iran in chaos.

    The US stopped its deliveries of nuclear fuel to the research reactor in Tehran. In 1980, Iraq attacked Iran to take control of its oil fields, sparking an eight-year war. Western companies, including German ones, abandoned their cooperation with the Iran nuclear program.

    In the early 1980s, rumors began circulating that Iraq was building a nuclear weapon.

    Israel, who regarded the Saddam Hussein regime as more of a threat than the Iranian mullahs, actually used information provided by the Iranian secret services to bomb Iraq’s nuclear reactor Osirak in 1981.

    After the Iran-Iraq war ended in 1988, Iran started importing technology from Pakistan, China and Russia to enrich uranium and develop its own nuclear fuel.

    The regime hoped to prove that Iran was capable of pursuing high-tech projects, and its nuclear program became a symbol of the nation’s strength.

    Iranian officials never denied the fact that Tehran also had the capacity to build a nuclear weapon in case of an emergency.

    Akbar Etemad, the man known as the father of Iran’s nuclear program, believed that no country has the right to dictate how other nations pursue its nuclear policy, and he maintained that position even after the Islamist Revolution in 1979.

    Fereydoun Abbasi, who led Iran’s atomic agency until he was killed in recent Israeli air strikes, also publicly stated that Iran needed to be able to quickly reach weapons-grade levels of enrichment if the government demands it.

    Trump’s vain hope of a ‘better deal’

    In 2003, IAEA inspectors and satellite surveillance indicated the possibility of Iran pursuing a secret military nuclear program.

    Germany’s foreign minister at the time, Joschka Fischer, convinced his counterparts in the UK and France to start negotiations with Iran, aiming to impose stricter controls of the Iranian nuclear program with the help of the IAEA.

    After 12 long years of talks, the US, China, Russia and the three European powers came to a comprehensive nuclear agreement with Iran knowns the JCPOA.

    In 2018, however, US President Donald Trump took his country out of the agreement to get a “better deal.” Iran responded by gradually forgoing its commitments and began high-level uranium enrichment in 2019.

    Today, Iran has about 400 kilograms (more than 880 pounds) of highly enriched uranium and many advanced centrifuges used to process the radioactive element.

    Libya as a lesson to Iran

    Despite the US claiming that Iran’s nuclear program has now been “obliterated,” many experts warn that Iran could rebuild its nuclear facilities.

    The Iranians “retain a significant capability to restart their nuclear program and make a nuclear weapon if that’s what they want to do,” said Jeffrey Lewis, a non-proliferation expert at the Middlebury Institute of International Studies in Monterey, California.

    Lewis told DW that “there are many facilities that were not struck” in the bombing.

    And Iran is very unlikely to compromise in the near future, said Iranian-born reporter Mehrdad Farahmand.

    “Iran sees backing down in a wartime situation as weakness” and this perception is possibly the biggest obstacle to a revival of diplomacy, he said.

    Looking ahead, Iran’s perspective is likely to be shaped by the examples of Libya and North Korea, according to Kelsey Davenport.

    “It wouldn’t be surprising if the advisors around the supreme leader are arguing that Iran needs nuclear weapons to defend itself from further attack,” the non-proliferation expert told DW.

    “Iran looks at the example of Libya, where Moammar Gadhafi gave up the country’s nuclear weapons program, returned to good standing in NPT, and then later was overthrown by Western-backed forces,” Davenport said.

    In turn, North Korean abandoned the Non-Proliferation Treaty in 2003, developed its nuclear weapons, and the regime — now lead by Kim Jong Un — remains firmly in power.

  • New research confirms that neurons form in the adult brain

    New research confirms that neurons form in the adult brain

    A study in the journal Science presents compelling new evidence that neurons in the brain’s memory centre, the hippocampus, continue to form well into late adulthood. The research from Karolinska Institutet in Sweden provides answers to a fundamental and long-debated question about the human brain’s adaptability.

    The hippocampus is a brain region that is essential for learning and memory and involved in emotion regulation. Back in 2013, Jonas Frisén’s research group at Karolinska Institutet showed in a high-profile study that new neurons can form in the hippocampus of adult humans. The researchers then measured carbon-14 levels in DNA from brain tissue, which made it possible to determine when the cells were formed.

    Identifying cells of origin

    However, the extent and significance of this formation of new neurons (neurogenesis) are still debated. There has been no clear evidence that the cells that precede new neurons, known as neural progenitor cells, actually exist and divide in adult humans.

    “We have now been able to identify these cells of origin, which confirms that there is an ongoing formation of neurons in the hippocampus of the adult brain,” says Jonas Frisén, Professor of Stem Cell Research at the Department of Cell and Molecular Biology, Karolinska Institutet, who led the research.

    From 0 to 78 years of age

    In the new study, the researchers combined several advanced methods to examine brain tissue from people aged 0 to 78 years from several international biobanks. They used a method called single-nucleus RNA sequencing, which analyses gene activity in individual cell nuclei, and flow cytometry to study cell properties. By combining this with machine learning, they were able to identify different stages of neuronal development, from stem cells to immature neurons, many of which were in the division phase.

    To localize these cells, the researchers used two techniques that show where in the tissue different genes are active: RNAscope and Xenium. These methods confirmed that the newly formed cells were located in a specific area of the hippocampus called the dentate gyrus. This area is important for memory formation, learning and cognitive flexibility.

    Hope for new treatments

    The results show that the progenitors of adult neurons are similar to those of mice, pigs and monkeys, but that there are some differences in which genes are active. There were also large variations between individuals – some adult humans had many neural progenitor cells, others hardly any at all.

    “This gives us an important piece of the puzzle in understanding how the human brain works and changes during life,” explains Jonas Frisén. “Our research may also have implications for the development of regenerative treatments that stimulate neurogenesis in neurodegenerative and psychiatric disorders.”

    The study was conducted in close collaboration with Ionut Dumitru, Marta Paterlini and other researchers at Karolinska Institutet, as well as researchers at Chalmers University of Technology in Sweden.

    The research was funded by the Swedish Research Council, the European Research Council (ERC), the Swedish Cancer Society, the Knut and Alice Wallenberg Foundation, the Swedish Foundation for Strategic Research, the StratRegen programme, the EMBO Long-Term Fellowship, Marie Sklodowska-Curie Actions and SciLifeLab. Jonas Frisén is a consultant for the company 10x Genomics. See the scientific article for a complete list of potential conflicts of interest.

    As humanity looks to the stars, the dwarf planet Sedna presents an intriguing challenge for scientists and adventurers alike. Located billions of miles from the Sun, Sedna offers a rare opportunity to explore the outer reaches of our solar system. With its next closest approach to the Sun set for 2076, researchers are keen to capitalize on this chance to gather invaluable data about the early solar system. Recently, a team of scientists has proposed utilizing nuclear propulsion and solar sails to reach Sedna in a mere seven years, a feat that could revolutionize space exploration.

    Flying to Sedna with Two Experimental Spacecraft Concepts

    Back in 2003, astronomers made a groundbreaking discovery when they identified Sedna, a distant object orbiting the Sun far beyond Pluto. Named after the Inuit goddess of the ocean, Sedna provided a tantalizing glimpse into the mysteries of the outer solar system. With a staggering orbital period of 10,000 years, it travels billions of miles from the Sun. However, its upcoming perihelion in 2076 offers a window of opportunity for exploration.

    In a recent paper published on arXiv, a team of researchers from Italy outlined two pioneering propulsion concepts that could significantly cut travel time to Sedna. The first involves a nuclear fusion rocket engine, while the second explores the potential of a solar sail. These innovative technologies promise to reduce the journey to Sedna by more than 50%, making it feasible to reach the dwarf planet in just seven to ten years. At its closest approach, Sedna will be within 7 billion miles of the Sun, a distance that might be surmountable with these advanced spacecraft.

    Nuclear Propulsion and Solar Sailing

    The first of the proposed technologies is the Direct Fusion Drive (DFD) rocket engine, currently under development at Princeton University’s Plasma Physics Laboratory. This engine aims to generate both thrust and electrical power through controlled nuclear fusion reactions. The DFD presents a promising alternative to conventional propulsion methods, offering a high thrust-to-weight ratio and continuous acceleration. However, several engineering challenges remain, such as plasma stability and heat dissipation, which need to be addressed before it can be deployed in deep-space missions.

    On the other hand, the concept of solar sailing utilizes the Sun’s energy to propel a lightweight spacecraft at high speeds. This method gained traction with the successful mission of LightSail 2 by The Planetary Society in 2019. In this approach, a large sail captures photons from the Sun, providing thrust without the need for heavy fuel. The Italian researchers propose enhancing this concept by coating the sails with a material that releases molecules when heated, further increasing propulsion through thermal desorption. This could enable a solar sail mission to reach Sedna in just seven years, although it would be limited to a flyby.
