Ukraine's military has launched a significant drone strike on Russian energy infrastructure in the Black Sea, targeting the port of Novorossiysk. According to Ukrainian drone forces commander Robert Brovdi, the overnight attack hit the Admiral Makarov missile carrier in the port, which serves as Russia's largest oil exporting outlet on the Black Sea.The attack is part of Ukraine's broader strategy to disrupt Russian energy exports and reduce Moscow's revenues. Ukraine has increased its attacks on Russian energy infrastructure in recent weeks, aiming to halt Russian oil exports and impact the Russian economy.Russian authorities reported that at least eight people, including two children, were injured in Novorossiysk. Videos posted on Telegram showed a fire at one of the oil port's docks. Novorossiysk Mayor Andrei Kravchenko stated that debris from drones had fallen on two locations in the city, including a residential area.Russia's military claimed that air defense units had downed 148 Ukrainian drones over a three-hour period. The Caspian Pipeline Consortium (CPC) terminal, located in the Novorossiysk port area, exports oil from Kazakhstan and has major US oil companies, such as Chevron and ExxonMobil, as shareholders.The attack on Novorossiysk comes amid a series of Ukrainian drone strikes on Russian oil infrastructure. On the previous day, Ukrainian drones struck Russia's Baltic Sea port of Primorsk and the NORSI oil refinery in Nizhny Novgorod. These attacks are part of Ukraine's efforts to reduce Moscow's revenues from oil sales, which are crucial for the Russian economy.In response to the attacks, Russia's Ministry of Defence accused Ukraine of deliberately targeting the CPC terminal to inflict economic damage on its largest shareholders, including US and Kazakh energy companies.

The deployment of reflective mirrors on satellites and the launch of thousands more satellites into low Earth orbit could have significant consequences for human health and ecosystems. Leading sleep and circadian rhythm researchers have raised concerns about the potential disruption to natural night-time light environments.The US Federal Communications Commission (FCC) is considering plans by Reflect Orbital to illuminate parts of the Earth at night using reflective satellites, as well as applications from SpaceX that could dramatically expand satellite numbers in low Earth orbit.2,500 researchers from over 30 countries have expressed concerns that altering the light-dark cycle could disrupt biological clocks that regulate sleep and hormone secretion in humans and animals, migration in nocturnal species, seasonal cycles in plants, and the rhythms of marine phytoplankton.Prof Charalambos Kyriacou, president of the European Biological Rhythms Society (EBRS), emphasized that "plants need the night" and that eliminating it could have global implications for food security.Reflect Orbital aims to use satellites equipped with large reflective mirrors to redirect sunlight onto areas roughly 5km to 6km wide "on demand", with brightness adjustable "from full moon to full noon".Meanwhile, SpaceX has proposed launching up to 1m satellites to create a giant solar-powered computing network in orbit designed to run artificial-intelligence workloads.Ruskin Hartley, chief executive of DarkSky International, noted that scientific studies have already shown that the existing number of satellites in orbit has increased diffuse night sky brightness by roughly 10%.Experts warn that if current trends in satellite launches and debris generation continue, night sky brightness could increase substantially over the coming decade, approaching the threshold astronomers have set for preserving naturally dark skies.

The UK medicines regulator has opened an inquiry into a growing number of clinics that sell injectable peptides while promoting them as cures for everything from ageing to injury recovery. The investigation, disclosed by the Guardian, focuses on whether these businesses are breaching the Human Medicines Regulations 2012 by making unauthorised medicinal claims. Interest in peptide‑based treatments has surged in recent years, driven by social‑media influencers, some healthcare professionals, and direct‑to‑consumer marketers. Yet the scientific foundation for most of these claims is weak, with the bulk of research confined to animal models or cell‑culture studies. According to an MHRA spokesperson, any clinic that advertises a peptide as having therapeutic benefits must treat the product as a medicine, which triggers a comprehensive regulatory framework. "If clinics offering peptide injections make medicinal claims for those treatments, the products will be considered medicines and subject to regulation," the agency warned, adding that it will act against any identified breaches. Guardian reporters identified several high‑ranking Google search results that list peptides such as Cortexin (promoted for neuroprotection), BPC‑157 (claimed to aid tissue repair), and Thymosin Alpha (advertised to boost immunity). After being contacted, one clinic removed the statements from its website. Another clinic, while acknowledging the limited human evidence, continued to market seven specific peptides, providing price lists (£350 per month for a single peptide, £450 for two) and offering delivery via vials, syringes, or pre‑filled pens for an additional fee. During a free consultation, a clinician highlighted the experimental nature of the products, noting the absence of large‑scale, randomised clinical trials and recommending a break of four to eight weeks between treatment cycles to mitigate unknown risks. The clinician suggested BPC‑157 for post‑exercise recovery, describing it as a facilitator of cellular repair and blood flow, but warned against its use in smokers or individuals with a family history of cancer due to potential angiogenic effects. The second peptide discussed was MOTS‑C, portrayed as a mitochondrial enhancer that could improve stress resilience, lower insulin resistance, and reduce visceral fat by boosting cellular energy production (ATP). The MHRA confirmed it is reviewing whether the clinician’s statements constitute medicinal claims. The clinic defended its approach, emphasizing that it clearly informs clients that the peptides are not licensed medicines and that the evidence base is largely pre‑clinical. In a broader statement, Lynda Scammell, head of borderline products at the MHRA, explained that peptide products may be marketed as cosmetics, supplements, or medicines, and each case is assessed on its intended use, pharmacological effect, and supporting evidence. She added, "We disregard claims that products are for ‘research purposes’ if it is clear that such claims are being used as an attempt to avoid medicines regulations." Peptides are short chains of amino acids, some of which occur naturally (e.g., insulin). While synthetic peptide analogues like semaglutide and tirzepatide have secured approval for weight‑loss treatments, many of the compounds promoted by these clinics remain experimental and lack the rigorous safety and efficacy testing required for medicinal products.

The increasing congestion of Earth's orbit with satellites is raising concerns about the environmental impact of space activities. A recent UN report highlighted the urgent need for sustainable practices to manage potential orbital congestion and environmental impacts.One of the most pressing issues is the risk of space debris, also known as 'space junk', which includes discarded rocket stages and defunct satellites. The surge in orbital activity has created a significant collision risk, and there have already been a handful of crashes. In 2007, a Chinese anti-satellite weapon test intentionally blew up a weather satellite, creating a dangerous cloud of space debris.Researchers fear that the impact of space activities on the ozone layer, which shields the planet from radiation, could be significant. A study found that roughly 10% of particles in the stratosphere contain metals that originated from space activities such as rocket launches.The Guardian has launched an interactive project to visualize the tens of thousands of human-made objects spinning around the globe. The project reveals a significant problem which, if left unchecked, could disrupt some of humanity's most important services such as the internet and weather prediction.As a global society, we rely on satellites constantly, not only to help us navigate around using Google Maps, but also to provide internet access and, critically, predict the weather. Space-based monitoring of the Earth also allows researchers to track deforestation, desertification, glacier and ice-cap melt, and the spread of oil spills.

India has officially started its historic census, initiating the nationwide process of counting every resident. This marks a significant step in gathering comprehensive demographic data for the country.

Central Israel was struck by one of Iran’s most extensive missile barrages in recent weeks, underscoring a rapid escalation in regional tensions.

NASA's Artemis II space mission has successfully launched from Florida, embarking on a historic journey around the moon with four astronauts on board. This mission marks a significant milestone in the United States space agency's plan to return humans to the moon and eventually send astronauts to Mars.The 32-storey rocket rose from NASA's Kennedy Space Center in Cape Canaveral, where tens of thousands gathered to witness the liftoff. The Artemis II crew, consisting of NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen, are set for a nearly 10-day journey around the moon and back.“On this historic mission, you take with you the heart of this Artemis team, the daring spirit of the American people and our partners across the globe, and the hopes and dreams of a new generation,” said Charlie Blackwell-Thompson, the launch director. “Good luck, Godspeed Artemis II. Let’s go.”During the mission, the astronauts will spend the first one to two days in high Earth orbit carrying out extensive systems checks. They will then perform a critical engine burn known as translunar injection, which will send the spacecraft out of Earth's orbit and onto a trajectory towards the moon.The journey will take several days, during which the crew will continue monitoring spacecraft systems as they travel farther from Earth. Orion will then fly behind the moon on a free-return trajectory, a path that naturally swings the spacecraft back towards Earth using the gravity of both the moon and Earth, with minimal fuel required.After the lunar flyby, the crew will spend several days traveling back to Earth while carrying out additional deep-space tests on power systems, thermal controls, and crew operations. As Orion approaches Earth, the capsule will re-enter the atmosphere at speeds of about 40,233km per hour (25,000 miles per hour), before splashing down in the Pacific Ocean, where recovery teams will retrieve the crew.

A team of FBI agents has arrived in Cuba to launch an independent investigation into a deadly shootout between local border patrol officers and a Florida-tagged speedboat. The incident occurred on February 25, when 10 Cuban nationals attempted to enter Cuba by speedboat, armed with nearly 13,000 rounds of ammunition, 13 rifles, and 11 pistols.The shootout resulted in the deaths of five people, with the others being wounded and taken into custody. The Cuban government has stated that the assailants were Cuban exiles who came from the US with the intent to sow chaos and attack military units.The US embassy in Havana announced the FBI agents' arrival, stating that the trip was part of a "thorough and independent investigation" into the incident. An embassy official said the US would verify Havana's version of events, adding that the US would make decisions based solely on US interest, US law, and the protection of US citizens.Tensions have been high between the two nations since January, when US President Donald Trump imposed a virtual oil blockade on the island. The incident has sparked concerns about the escalating tensions between the US and Cuba, with the FBI's investigation expected to shed more light on the circumstances surrounding the deadly shootout.

NASA's Artemis II mission has successfully launched, marking a significant milestone in space exploration. The mission, which launched on Wednesday, is the first crewed mission to the moon's vicinity since the Apollo program ended in 1972.The 322-foot Space Launch System (SLS) rocket lifted off at 6:35pm ET (22:35 GMT) from Cape Canaveral, Florida, sending the Orion crew capsule on a 10-day journey around the moon and back to Earth.The crew, consisting of NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian astronaut Jeremy Hansen, will follow a 'free-return' trajectory that swings around the moon to prove the spacecraft can sustain a crew on future missions.The mission plan includes high Earth orbit checks, a translunar injection to propel the spacecraft towards the moon, and a lunar flyby on April 6. The spacecraft will reach its closest approach to the moon, approximately 4,000-6,000 miles (6,450-9,650km) above the lunar surface.After the flyby, the crew will conduct deep-space science and medical monitoring before re-entering Earth's atmosphere and splashing down in the Pacific Ocean on April 10.NASA's next mission, Artemis III, is currently planned for 2027 and will involve the Orion spacecraft docking with a lunar lander in Earth orbit.
