For first time, Webb telescope discovers an alien planet
In addition to providing a trove of information about the early universe, the James Webb Space Telescope since its 2021 launch has obtained valuable data on various already-known planets beyond our solar system, called exoplanets. Now, for the first time, Webb has discovered an exoplanet not previously known.
Webb has directly imaged a young gas giant planet roughly the size of Saturn, our solar system's second-largest planet, orbiting a star smaller than the sun located about 110 light-years from Earth in the constellation Antlia, researchers said. A light-year is the distance light travels in a year, 9.5-trillion km.
Most of the roughly 5,900 exoplanets discovered since the 1990s have been detected using indirect methods, such as through observation of the slight dimming of a star's light when a planet passes in front of it, called the transit method. Less than 2% of them have been directly imaged, as Webb did with the newly identified planet.
While this planet is large when considered in the context of our solar system, it is actually the least massive one ever discovered through direct imaging — 10 times less massive than the previous record holder. This speaks to the sensitivity of Webb's instruments.
This discovery was achieved using a French-produced coronagraph, a device that blocks out the bright light from a star, installed on Webb's Mid-Infrared Instrument, or MIRI.

The future of the bee lab: a critical moment for native bee research
Sam Droege, 66, holds a native dead bee specimen under a microscope at the USGS Native Bee Inventory and Monitoring Lab in Laurel, Maryland, on May 27 Image: Salwan Georges/The Washington Post In a lush field of tall grass and poison ivy, Sam Droege, a dedicated wildlife biologist, embarks on his daily commute to the government lab he has managed for over 23 years. However, the future of this vital institution hangs in the balance as the Trump administration's 2026 budget proposal threatens to defund the lab, jeopardising crucial research on native bees and their role in maintaining biodiversity. As Droege reflects on his decades of work, he faces an uncertain future, one that could have dire consequences for the environment and food production. Droege, a slender 66-year-old with long white hair styled in neat French braids, is one of the world's leading experts on native bees. These pollinators, which thrive in the wild, differ significantly from honeybees, which are farmed for profit. While both bee types face similar threats, including pesticides and habitat loss, Droege's work focuses on understanding the behaviour and ecology of native bees, which are essential for pollinating an estimated 80 percent of flowering plants worldwide. The lab, which houses one of the largest bee collections in the country, has amassed over one million specimens, many of which are stored within its modest walls. However, with active fieldwork on hold and no new research projects underway, the potential closure of the lab comes at a critical juncture for bees, which have already experienced significant population declines in recent years.

Hollis Woodard, an associate professor at the University of California at Riverside, describes the lab as "essentially irreplaceable." She relies on its data for her research nearly every day and emphasises that losing this facility would severely hinder efforts to track and conserve native bee populations. The lab's budget is modest, consisting primarily of Droege's salary and that of his sole employee, a lab manager hired four years ago. The funding they receive from the government ranges from a mere $3,000 to $12,000 annually. This financial instability is compounded by the Trump administration's proposal to eliminate grants and research programs that "duplicate other Federal research programs," which could lead to the lab's closure as soon as October 1. Droege expresses his frustration, stating, "I'm sad that people have let it happen." Despite being warned not to speak publicly about the proposed closure, he feels compelled to raise awareness about the implications of losing a publicly funded lab on bee research and science. "Nothing radical," he insists, but the stakes are undeniably high. As he prepares for the worst, Droege has opened up a garden once filled with native plants to attract specific bee species to the public. "If we have to leave, who will take care of this?" he asks, highlighting the urgency of the situation. A native bee specimen, speared by a thin needle and pinned into foam, under the microscope. Image: Salwan Georges/The Washington Post The bee lab is not easy to find. Located just 20 miles from Washington, it has no official address and can only be accessed by entering precise longitude and latitude coordinates into a GPS. Once through the hidden metal gate and down a dirt road, visitors encounter two unassuming buildings. The first, an old garage, was once the main lab but is now cluttered with dusty books, mosaic-decorated file cabinets, and a long wooden table that was once a bowling alley. Droege's work is not only about identifying bee species but also about understanding their ecological roles. He notes that native bees are crucial for maintaining the unique biodiversity of forests, prairies, grasslands, deserts, and wetlands. The more researchers track these bees, the better they can comprehend the role different species play in pollinating crops such as pumpkins, apples, tomatoes, and blueberries. The urgency of this research is underscored by alarming statistics. Honeybee keepers reported losing over 60 percent of their colonies in the past year, a trend linked to viruses carried by Varroa mites, common parasites of honeybees. The decline of honeybees serves as a warning for all pollinators, including native bees, which are disappearing at an alarming rate due to habitat loss and climate change. Droege's dedication to his work is evident as he examines bee specimens under a microscope, revealing the intricate details that distinguish each species. "Identifying a bee is no small feat," he explains, noting that most species are smaller than a grain of rice. Yet, the wonders of their diversity are crucial for understanding the health of ecosystems.

French scientists find new blood type in Guadeloupe woman
The new blood type is dubbed "Gwada negative". Image: / Pexels A French woman from the Caribbean island of Guadeloupe has been identified as the only known carrier of a new blood type, dubbed "Gwada negative," France's blood supply agency has announced. The announcement was made 15 years after researchers received a blood sample from a patient who was undergoing routine tests ahead of surgery, the French Blood Establishment (EFS) said on Friday. "The EFS has just discovered the 48th blood group system in the world!" the agency said in a statement on social network LinkedIn. "This discovery was officially recognised in early June in Milan by the International Society of Blood Transfusion (ISBT)." The scientific association had until now recognised 47 blood group systems. Thierry Peyrard, a medical biologist at the EFS involved in the discovery, told AFP that a "very unusual" antibody was first found in the patient in 2011. However, resources at the time did not allow for further research, he added. Scientists were finally able to unravel the mystery in 2019 thanks to "high-throughput DNA sequencing", which highlighted a genetic mutation, Peyrard said. The patient, who was 54 at the time and lived in Paris, was undergoing routine tests before surgery when the unknown antibody was detected, Peyrard said. This woman "is undoubtedly the only known case in the world," said the expert. "She is the only person in the world who is compatible with herself," he said. Video Player is loading.

The name "Gwada negative", which refers to the patient's origins and "sounds good in all languages", has been popular with the experts, said Peyrard. The ABO blood group system was first discovered in the early 1900s. Thanks to DNA sequencing the discovery of new blood groups has accelerated in recent years. Peyrard and colleagues are now hoping to find other people with the same blood group. "Discovering new blood groups means offering patients with rare blood types a better level of care," the EFS said. AFP
