Have you ever wished for a camera that could photograph a huge slice of the night sky in a single shot? NASA is about to launch exactly that kind of camera into space. The Nancy Grace Roman Space Telescope is scheduled to lift off no earlier than 7:26 a.m. Eastern Time on August 30, 2026. It will ride a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA's Kennedy Space Center in Florida. The telescope is named after Nancy Grace Roman, NASA's first chief astronomer, who helped make the Hubble Space Telescope possible decades ago. Roman's main mirror is about the same size as Hubble's mirror. However, its camera has a field of view at least 100 times larger, so it can capture much bigger patches of space in one clear picture. After launch, Roman will travel to a location called the second Sun-Earth Lagrange point, far beyond the Moon. From there, scientists hope it will help them study dark energy and dark matter, discover new exoplanets, and map billions of galaxies. The mission is planned to run for at least 5 years, with a goal of lasting 10.

Why would an owl make noise at one of the most vulnerable moments of its life? Researchers at Hokkaido University may have found an answer. A team led by Professor Masaoki Takagi studied the Ryukyu scops owl, a small owl that lives on Minami-daito Island in Japan. Many mammals and birds make sounds while mating, but scientists were not sure why. To find out, the researchers played recorded owl calls, including copulation calls, to wild owls and measured how strongly each bird called back. Both male and female owls responded strongly when they heard a copulation call, and they could clearly tell it apart from other owl sounds. The team also found that owls called more often when an outside owl seemed to be nearby, suggesting the calls might work like a warning sign that says, 'this territory, and this partner, already belong to someone.' This is the first study to test whether male and female birds respond differently to copulation calls. The findings were published online on August 22, 2026, in the journal Animal Behaviour. The results add a new piece to the puzzle of how animals use sound to communicate complex social messages.

What if a medicine you simply breathe in could help your cells finish building a protein they had given up on? Researchers at the University of Toronto, led by Associate Professor Bowen Li, are testing exactly this idea. Their target is a group of genetic errors called nonsense mutations. Li compares a nonsense mutation to a stop sign appearing in the middle of a road: the cell's protein-building machinery hits the sign, slams on the brakes, and the protein is never finished. Nonsense mutations cause about 11 percent of inherited genetic disorders, including some cases of cystic fibrosis and certain muscular and neurological diseases. The team engineered a modified transfer RNA, or tRNA, that helps cells read straight through the false stop sign and complete the protein. In tests on mice with cystic fibrosis caused by a nonsense mutation, an inhaled version of the therapy reached the lungs, stayed active there for more than 40 days, and safely restored working copies of the missing protein. The therapy also worked well together with Trikafta, a cystic fibrosis drug already used in clinics. The study was published on August 27, 2026, in the journal Science. The team hopes to begin moving the treatment toward human trials within the next few years.

Could a single ancient street reveal how an entire city changed its identity over hundreds of years? In the ancient city of Side, on Turkey's Mediterranean coast, archaeologists say yes. Turkey's Minister of Culture and Tourism, Mehmet Nuri Ersoy, announced that excavation teams have fully uncovered Street B, a monumental road about 390 meters long. The project is part of Turkey's 'Heritage for the Future' program. Along the street, researchers identified 3 grand gateways: the West Gate, the Heracles Gate, and the North Bath Gate. The Heracles Gate stands out because of stone panels carved with the Twelve Labors of Heracles, the legendary hero from Greek mythology, along with images of the gods Athena, Zeus, Artemis, Hygeia, and Tykhe. These carved panels date from the early 3rd century AD, but researchers found they were reused as building material when the gate was rebuilt in Late Antiquity, probably in the 5th century AD. By the 5th century, the same street had become a grand entrance leading to the city's Episcopal Palace, showing how Side changed from a Roman city into an early Christian one. Minister Ersoy said the finished excavation reveals 'important traces' of Side's long transformation from the Roman period to Late Antiquity.
