Science journalist Maria Smilios was editing a book on orphan lung diseases when one line caught her attention. In a chapter about a rare lung disease, the author commented that perhaps a cure could be discovered as quickly as the cure for tuberculosis was found at Sea View Hospital on Staten Island in the 1950s. Smilios began researching and learned how the first clinical trial for a lifesaving antibiotic happened at Sea View under the watchful supervision of experienced nurses — all of them ...read more

NASA intends to take an unprecedented 3D observation of the sun this month. In doing so, the agency hopes to understand why its outer atmosphere — the corona — is hotter than its surface, how does the solar wind work, and how the corona transforms into solar wind. As a bonus, the mission will take 3D pictures of a solar eclipse, from space.Learning More About the Sun's SurfaceThe system that will make these things possible is made up of four small satellites that will work together to create ...read more

Some baleen whales, or whales that have plates in their mouths to help sieve out plankton, sing low-frequency songs to not only attract potential mates but also keep them safe from killer whale attacks. According to new research published in Marine Mammal Science by the University of Washington (UW), these low-frequency songs are part of a baleen whale’s fight-or-flight response. Whales in Fight or FlightBaleen whales are often more solitary, as compared to orcas, and include species like hum ...read more

Air traffic controllers now have something new to worry about: space junk. A report warns the risk of parts left over from a launch rocket or other debris plummeting into global flight paths is now 26 percent a year, according to a report in the journal Nature.While the chance of debris hitting an aircraft is low, its presence in flight paths could still pose a big enough risk that routes will need to be altered — inconveniencing passengers. Such disruptions are not unheard of. In 2022, a 20-t ...read more

Once again, the microbiome proves to be a key player in human health. The diverse microbial community we inherit at birth serves multiple functions, from aiding digestion and nutrient production to training our immune system and even influencing brain chemistry. A recent study, published in EMBO Molecular Medicine, builds on the exploration of the gut-brain connection by linking anxiety regulation to microbial metabolites.Researchers from Duke-NUS Medical School and the National Neuroscience Ins ...read more

Every winter, public health departments report a rise in illnesses. Most of these infections are expected during the colder months, and the data features the usual lineup of suspects — acute bronchitis, influenza, pneumonia, and respiratory syncytial virus (RSV).This year has also seen a surge in norovirus, a highly contagious stomach bug. Starting November 2024, the percentage of positive tests for norovirus began to increase, which is to be expected in the colder months when people begin to ...read more

The story of Homo sapiens is written largely in artifacts. Countless tools, potsherds, and other relics line museum shelves, illuminating the world of our ancestors. But most of the time, this historical picture, though richly strewn with inanimate objects, lacks what would most bring it to life — the people themselves.To fill that void, Swedish archaeologist Oscar Nilsson has spent 30 years reconstructing the faces of the dead. With an artist's touch and 150 years of anatomical data at his di ...read more

A 2,000-year-old Roman scroll, scorched beyond repair, has miraculously been unfurled with the help of X-ray scanning and artificial intelligence. The scroll, named PHerc. 172, is one piece to a larger puzzle — for years, researchers have pursued restoration of the Herculaneum papyri, a series of over 1,800 scrolls burned and carbonized during the eruption of Mount Vesuvius in 79 A.D. PHerc. 172 is the latest remnant of the extensive papyri collection to be digitally opened, reviving lost his ...read more
