Researchers from Stanford, Oxford and UC San Diego have demonstrated a proof‑of‑concept wearable ultrasound patch that can monitor a baby’s heart rate and blood flow continuously, aiming to reduce false alarms and missed complications in pregnancy.A Patch That Turns Ultrasound Into a Wearable SensorThe device, dubbed UPatch, adheres to the abdomen and remains operational for hours, capturing real‑time images of the foetus and umbilical cord. Unlike intermittent hospital scans, the patch records a continuous stream of data, allowing clinicians to establish a personal baseline for each pregnancy and spot deviations instantly.Trial Results Show Near‑Parity With Conventional ScansIn a study published in Nature Biotechnology, the team evaluated the patch in two cohorts:62 pregnant participants – single‑time‑point blood‑flow measurements from UPatch matched those from standard handheld ultrasound.52 women – continuous monitoring revealed dynamic fluctuations in fetal blood flow that brief scans would miss.A pre‑eclamptic case where UPatch detected severe intra‑uterine growth restriction, prompting a timely caesarean delivery and preventing stillbirth.Lead author Tom Park highlighted that the technology captures transient changes without over‑diagnosing, addressing a key limitation of current intermittent methods.Potential Shift in Prenatal Care and Global HealthSenior author Prof Sheng Xu emphasized that continuous monitoring could become a routine part of prenatal visits, especially in low‑resource settings where access to skilled sonographers is limited. Dr Antoniya Georgieva noted the broader impact: reducing stillbirth rates, providing richer data for research, and enabling earlier interventions for conditions like pre‑eclampsia.Roadmap Toward a Fully Wireless Home‑Use SystemThe current prototype is tethered to external electronics for placement, but the team is already engineering a wireless version that patients could wear during daily activities and at home. Their long‑term vision is a seamless, battery‑efficient system that integrates with tele‑health platforms, delivering real‑time alerts to clinicians wherever the mother is.

Ring 5 Redefines the Smart Ring Form FactorOura introduced the Ring 5, a 40% smaller iteration of its flagship device, measuring just 2.28 mm in thickness. The ring packs the health‑tracking capabilities of a smartwatch—sleep, stress, readiness and heart health—into a jewellery‑like profile while extending battery life. It will ship on 4 June with a retail price of £399 (€399/$399) and a mandatory $5.99 monthly subscription.40% reduction in size versus Ring 4Battery life increased (exact hours not disclosed)Subscription‑based model adds recurring revenueFinancial Outlook: $1 bn Revenue Target and $11 bn ValuationOura reports roughly 5 million paying subscribers and a four‑fold revenue growth over the past two years, projecting $1 bn in revenue for 2025. The company is currently valued at about $11 bn ahead of an IPO slated for later this year.Market Implications: Accelerating Smart‑Ring Adoption and Competitive LandscapeAnalyst firm FDM CCS Insight estimates 4 million smart rings shipped in 2025, a figure that has more than doubled each year for the past two. While still dwarfed by the 175 million smartwatches shipped in the same period, rings are gaining traction among both traditional smartwatch users and those who prefer a less conspicuous device. Oura’s focus on sleep‑first tracking and a “female‑first” design philosophy differentiates it from larger players such as Apple.What’s Next: IPO Timing and Expansion of Proactive Health ServicesWith a global footprint that now includes offices in Helsinki, London, Los Angeles, San Diego and dual headquarters in San Francisco and Oulu, Oura is positioning the Ring 5 as a gateway to broader health‑care services. Upcoming software features—such as a health radar for early detection of blood‑pressure spikes and GLP‑1 weight‑loss monitoring—signal a shift toward proactive health management. Investors will be watching the IPO filing later in 2026 for clues on how the company plans to monetize these new services and sustain its growth trajectory.

The Lead: Iran's World Cup Visa DilemmaIran's football federation has demanded multiple-entry US visas for its World Cup squad, which will play matches across the United States. The team has relocated its base camp from the US to Mexico due to ongoing visa complications and heightened geopolitical tensions between the two nations.The Event Details: Visa Requirements and Base Camp RelocationFFIRI president Mehdi Taj stated that the US should issue multiple-entry visas for all players and support staff, as they would need to leave and re-enter the US multiple times during the tournament. The Iranian squad has not yet been issued US visas, with several members attending visa appointments in Turkiye where they have been training.The team has also applied for Canadian visas as a contingency plan in case they proceed to the knockout stages, which are allocated to venues in Canada. This preparation comes amid the ongoing regional conflict between the US and Iran that began in February.FIFA confirmed on Monday that Iran's World Cup training base camp had been relocated from the US to Mexico upon the team's request. Iran had originally selected a sports complex in Tucson, Arizona, but later sought a change. The team is now allocated Centro Xoloitzcuintle in Tijuana, Mexico, which is directly across the US-Mexico border from San Diego.The Impact Analysis: Geopolitics Meets International SportsThe visa complications highlight the intersection of sports and international relations. The US and Iran have been engaged in a regional conflict since February, with recent attacks occurring just days before the World Cup is set to begin. Despite a ceasefire being in place, the US carried out strikes on Iranian military sites, prompting the Islamic Revolutionary Guard Corps to launch an attack on what they described as an "American airbase" in the region.The relocation of Iran's base camp to Mexico demonstrates how geopolitical tensions can impact international sporting events. The proximity of Tijuana to the US border is expected to help with visa issues when the team needs to enter the country for their matches.The Prediction: Navigating World Cup Amid Regional TensionsAs the World Cup approaches, Iran's ability to participate fully will depend on the resolution of these visa issues. The team's preparation has been complicated by the need to apply for multiple visas and relocate their base camp at short notice. The situation underscores the challenges of hosting international sporting events in regions with geopolitical tensions.The World Cup, co-hosted by the US, Canada, and Mexico, runs from June 11 through July 19. Iran will open their campaign on June 15 against New Zealand in Los Angeles, face Belgium six days later, and conclude their Group G games against Egypt in Seattle on June 21.

Pochettino’s Email to Rejected USMNT PlayersIn a move that blends modern communication with squad management, Mauricio Pochettino sent a single email to every player who was not selected for the United States men’s national team’s 2026 World Cup roster. The email, distributed via the Football Daily newsletter, confirmed the 26‑man squad and left the rest with a brief, unapologetic notice.Roster Snapshot: Who Made the Cut and Who Was OmittedGio Reyna – the Borussia Mönchengladbach midfielder secured a spot despite limited club minutes.Diego Luna (Real Salt Lake) – awaiting confirmation, his name surfaced in fan speculation.Tanner Tessmann (Lyon) – similarly on the edge of selection.Aidan Morris (Middlesbrough) – omitted, sparking hopes for a late call‑up.Other notable exclusions include several MLS and European‑based players whose names have been circulating through spam folders.Transparency vs Personal Touch: The Coaching Communication DebateThe email has drawn criticism for lacking a personal phone call, especially for players who have invested years in the national program. Critics argue that a direct conversation respects the players’ dedication, while Pochettino defends the method as a realistic way to handle a large pool of hopefuls without “wasting” anyone’s time.Implications for Future USMNT SelectionsThis episode may set a precedent for how national teams communicate roster decisions in the digital age. If embraced, email could become the standard, streamlining the process but potentially eroding the personal rapport between coaches and players.Looking Ahead: Digital Communication in International FootballAs the sport continues to integrate technology, federations will need to balance efficiency with the human element. Future coaches might combine mass notifications with individualized follow‑ups to mitigate backlash while maintaining transparency.

Christian Pulisic, Tyler Adams and Weston McKennie have been named by head coach Mauricio Pochettino as the core of the United States 26‑man squad for the 2026 FIFA World Cup, set to launch on June 12 at SoFi Stadium.The 26‑Man Roster: Pulisic, Adams and McKennie Anchor the US Line‑upThe squad balances experience and fresh talent, featuring 13 World Cup debutants alongside 13 players who featured in Qatar 2022. The three goal‑scorers from Qatar – Pulisic, Tim Weah and Haji Wright – are retained.Goalkeepers: Chris Brady, Matt Freese, Matt TurnerDefenders: Max Arfsten, Sergino Dest, Alex Freeman, Mark McKenzie, Tim Ream, Chris Richards, Antonee Robinson, Miles Robinson, Joe Scally, Auston TrustyMidfielders: Tyler Adams, Sebastian Berhalter, Weston McKennie, Cristian RoldanAttacking mids/wingers: Brenden Aaronson, Christian Pulisic, Gio Reyna, Malik Tillman, Tim Weah, Alejandro ZendejasForwards: Folarin Balogun, Ricardo Pepi, Haji WrightNumbers Behind the Call‑up: 13 Debutants, 13 Veterans, and Key Goal‑ScorersThe even split underscores Pochettino’s intent to blend proven performers with new energy. Notable inclusions are Gio Reyna (limited minutes at Borussia Mönchengladbach) and Alejandro Zendejas (strong finish with Club América). Omissions include Diego Luna (injury) and Tanner Tessmann (Lyon).Strategic Implications for US Soccer on Home SoilCo‑hosting the tournament with Mexico and Canada gives the US a rare chance to spark a domestic soccer renaissance. The roster’s mix aims to deliver a “deep run” and inspire a new generation, as McKennie emphasized.Looking Ahead: Expectations for Group D and BeyondThe United States open Group D against Paraguay on June 12. Analysts expect a tactical 3‑4‑2‑1 formation, with Folarin Balogun competing for the lead striker role. Success could cement the US as a rising power and boost viewership ahead of the 2026 finals.

Live Announcement from Manhattan Sets the StageOn Tuesday afternoon, Mauricio Pochettino revealed the United States’ 26‑man squad for the 2026 World Cup during a live broadcast from Pier 17 in Manhattan. The roster mirrors the Guardian’s exclusive leak from the previous Saturday, confirming the final selections ahead of the tournament.Roster Composition: Experience, Age, and Club Distribution13 players with prior World Cup experience13 debutants making their first tournament appearancePlayers drawn from 16 different leagues across 12 countriesThe squad includes the core from the 2022 Qatar campaign: Christian Pulisic, Weston McKennie, Tyler Adams, Chris Richards and Tim WeahSurprise Omissions and Their Tactical ImplicationsThe most striking exclusion is Diego Luna (Real Salt Lake), who logged the second‑most attacking minutes under Pochettino. Central midfielders Tanner Tessmann and Aidan Morris were also left out, raising questions about depth in the midfield engine room. In contrast, Alejandro Zendejas (Club América) earned a spot despite only 139 minutes of playing time during the coach’s tenure, suggesting a strategic gamble on his upside.What the Squad Means for US Prospects at the 2026 World CupPochettino expressed confidence, stating the group is “the best” to achieve success. The team will train at the new National Training Center in Fayetteville, Georgia, before warm‑up friendlies against Senegal (31 May, Charlotte) and Germany (6 June, Chicago). The United States open the tournament on 12 June against Paraguay in Inglewood, followed by matches versus Australia (19 June, Seattle) and Turkey (25 June, Inglewood). The blend of seasoned internationals and fresh talent will be tested against a competitive Group C, and the early schedule offers both challenges and opportunities for the newcomers to make an impact.

Muslim Americans are channeling sorrow from the San Diego mosque shooting into a coordinated push for civil rights, security, and political advocacy, as highlighted at the annual Islamic Circle of North America (ICNA) conference in Baltimore.San Diego Mosque Shooting Sparks Nationwide MourningOn May 22, two gunmen opened fire at the Islamic Center of San Diego, killing Amin Abdullah, a security officer, and two civilians, Mansour Kaziha and Nadir Awad. The tragedy prompted a massive turnout of nearly 25,000 attendees at the ICNA conference, where speakers linked the attack to a broader wave of Islamophobia.Numbers Highlight Community ResponseThree victims killed in the San Diego attack.Approximately 25,000 people attended the ICNA conference.More than $3.5 million raised for victims’ families and security upgrades.Speakers emphasized voting, organizing, and donating to Muslim‑aligned candidates and institutions.Rising Islamophobia and Political MobilizationConference participants, including Lena Masri of CAIR, warned that anti‑Muslim rhetoric is intensifying, citing right‑wing figures such as Laura Loomer and Rep. Randy Fine. They highlighted legislative attacks, like Florida’s “terrorist” label on CAIR, and stressed the need for self‑security measures, as outlined by ICNA president Saad Kazmi.Advocates also connected domestic hate to U.S. support for Israel’s actions in Gaza, urging solidarity with Palestinians and calling for an end to policies that silence criticism of Israel.Future of Muslim Advocacy in the USLeaders predict a more assertive Muslim American presence in politics, emphasizing that rights must be actively “occupied.” Speakers such as Imam Tom Facchine and activist Leqaa Kordia urged continued engagement despite personal risks, signaling a shift from passive mourning to proactive defense of civil liberties.

The Switch in Base Camps The president of the Iranian football federation, Mehdi Taj, announced on Saturday that the team's World Cup training base has been moved to Mexico from the United States after getting approval from FIFA. This decision comes amid uncertainty surrounding the war in the Middle East and security concerns. Reasons Behind the Move Iran had initially been scheduled to train in Tucson, Arizona. However, due to potential visa issues and security concerns, the team will now be based in Tijuana, Mexico, just south of San Diego. The move is expected to resolve these issues, allowing the team to enter the US through Mexico. Additionally, the team 'may even be able to travel to and from Mexico using Iran Air flights,' according to Taj. World Cup Schedule and Implications Iran will play Group G games in Los Angeles against New Zealand on 15 June and Belgium on 21 June, then faces Egypt on 26 June in Seattle. This will be Iran's fourth straight World Cup appearance and seventh overall, though they have never advanced past the first round. FIFA's Stance and Previous Developments Earlier in March, it was reported that FIFA was unwilling to switch Iran's World Cup matches to Mexico following joint airstrikes on Iran by the US and Israel. At that time, Donald Trump mentioned that the 'life and safety' of Iran's players could be at risk if they traveled to the US. However, FIFA president Gianni Infantino later stated at the FIFA congress in Vancouver that Iran would play their World Cup games in the US as scheduled. The Future Outlook The change in base camps highlights the complexities and challenges that teams face when participating in international tournaments, especially in the context of geopolitical tensions. As the World Cup approaches, teams must navigate these issues while preparing for the competition.

Roster Announcement: Zendejas In, Tessmann OutClub América winger Alejandro Zendejas is on the United States' 26-man roster for this summer's World Cup, while Lyon defensive midfielder Tanner Tessmann is not included. The selections are the most notable new information gleaned from head coach Mauricio Pochettino's full World Cup roster, which was obtained by the Guardian and is authentic according to multiple sources with knowledge of Pochettino's selections.The roster confirms Zendejas's selection and Tessmann's omission, along with the inclusion of Borussia Mönchengladbach's Gio Reyna and the omission of Real Salt Lake's Diego Luna, both attacking midfielders, choices that were first reported by the Athletic. US Soccer declined to comment on the roster, which will be officially announced Tuesday at a nationally televised event in New York City.Reyna's Redemption: Past Controversies OvercomeReyna has been included despite playing only 520 minutes for Mönchengladbach this season, though he featured in the club's final five league matches. Pochettino has repeatedly praised the 23-year-old and singled him out as a player he's willing to include regardless of club form.During the 2022 World Cup, Reyna found himself at the center of one of the most dramatic and bizarre moments in men's national team history, having nearly been sent home from the tournament for behavioral issues. Not long afterwards, Reyna's parents became ensnared in a prolonged public falling out with US coach Gregg Berhalter. The situation has cast a shadow over Reyna in the years that followed.Sebastian Berhalter, the son of the former USMNT coach, is also on the roster. The 25-year-old never represented the US at the youth international levels, but forced his way into Pochettino's plans on the back of his considerable development since joining the Vancouver Whitecaps in 2022. Berhalter made the MLS Best XI last year as the Whitecaps' chief orchestrator en route to the club's first MLS Cup berth and first run to the Concacaf Champions Cup final. Berhalter also gives this team a dead-ball specialist, able to consistently place corner kicks in dangerous areas.Notable Exclusions: Luna and Tessmann Left BehindDespite being a key contributor throughout the USMNT's buildup to the World Cup, Diego Luna did not make the roster. He was the subject of frequent praise from Pochettino for his aggressiveness on both sides of the ball and scored four goals in 17 appearances in 2025, emerging as a breakout star. Despite missing March camp as he returned from an injury, Luna has returned in great form with four goals and two assists in seven MLS appearances (six starts) since 1 April.The 22-year-old also featured widely in promotional pushes ahead of the tournament, including a glitzy ad by tournament rights holder Fox. A spokesperson for the federation said earlier this week that Pochettino had nothing to do with the players selected to appear in those advertisements, some of which were produced months ago.The 28-year-old Zendejas is among Liga MX's most dangerous forwards, with 12 goals and seven assists in 2,443 minutes to lead Club América's attack. Despite his form, Pochettino has given Zendejas just 139 minutes across six appearances, with his most recent shift coming on 9 September against Japan.Tessmann, 24, suffered a muscle strain at Lyon two weeks ago but was still expected to be included in the roster. It's not immediately clear whether Tessman's exclusion is injury-related. The FC Dallas academy product appeared in 29 league matches for Lyon this season, starting 22 of them.Squad Composition: Strategic Balance for Tournament SuccessAs it stands, there are only four central or defensive midfielders on Pochettino's squad, with Weston McKennie joining Berhalter, Cristian Roldan and Tyler Adams. McKennie had seemed likely to play further upfield after his attacking midfield deployment in the March window.The defensive corps has gained the extra number, with 10 defenders picked to split time among four or five starting slots. Center-back Chris Richards is on the roster after Crystal Palace's manager announced he would miss the team's league finale this weekend with torn ligaments in his ankle. Missing among the central defenders is Noahkai Banks, the dual-national who left his international status in limbo and declined a US call-up in March as he weighed interest from Germany.Chicago Fire goalkeeper Chris Brady joins Matt Freese and Matt Turner on the roster. Brady, 22, is among the most in-form keepers in MLS and has been called into national team camp several times but never capped. Brady is the presumed No 3 behind Freese and Turner.In total, 13 members of Pochettino's squad have made their second World Cup roster, with the other half is comprised of first-time selections.Final Steps: Pre-Tournament Schedule and Roster ConfirmationThe USMNT will play their final two matches prior to the World Cup against Senegal on 31 May and Germany on 6 June. Managers must submit their rosters to Fifa by 1 June and are only able to change their squads after officially naming the 26-man roster in "exceptional cases", a loosely defined circumstance which must be approved by Fifa's medical committee.Complete USMNT 2026 World Cup RosterGoalkeepers (3): Chris Brady* (Chicago Fire, 0 caps/0 goals), Matt Freese* (New York City, 14/0), Matt Turner (New England Revolution, 53/0)Defenders (10): Max Arfsten* (Columbus Crew, 18/1), Sergiño Dest (PSV, 37/2), Alex Freeman* (Villarreal, 15/2), Mark McKenzie* (Toulouse, 27/0), Tim Ream (Charlotte FC, 80/1), Chris Richards* (Crystal Palace, 36/3), Antonee Robinson (Fulham, 52/4), Miles Robinson* (FC Cincinnati, 38/3), Joe Scally (Borussia Mönchengladbach, 24/0), Auston Trusty* (Celtic, 6/0)Midfielders (4): Tyler Adams (AFC Bournemouth, 52/2), Sebastian Berhalter* (Vancouver Whitecaps, 11/1), Weston McKennie (Juventus, 64/12), Cristian Roldan (Seattle Sounders, 45/0)Attacking midfielders/wingers (6): Brenden Aaronson (Leeds United, 57/9), Christian Pulisic (Milan, 84/32), Gio Reyna (Borussia Mönchengladbach, 36/9), Malik Tillman* (Bayer Leverkusen, 28/3), Tim Weah (Marseille, 49/7), Alejandro Zendejas* (Club América, 13/2)Strikers (3): Folarin Balogun* (AS Monaco, 25/8), Ricardo Pepi* (PSV, 35/13), Haji Wright (Coventry City, 20/7)
