Phys.org / Male bats sing in the rotor-swept zone of wind turbines, potentially raising collision risk
A research team led by the Museum für Naturkunde presents the first evidence that several bat species produce courtship songs in the immediate rotor-swept zone of wind turbines while circling around the nacelle. Data from ...
Phys.org / Hydrogen shell detected around Nova Persei 1901 may be a planetary nebula
Using NASA's SPHEREx space telescope, astronomers have observed remnants of the eruption of Nova Persei 1901. As a result, they detected a bipolar molecular hydrogen shell around this nova, which may be a large planetary ...
Phys.org / Python scales host microstructures that block bacterial biofilms—revealing potential for antimicrobial materials
Materials inspired by nature, or biomimetic materials, are nothing new. Scientists have designed water-resistant materials inspired by lotus leaves and rose petals, unsinkable metals based on the air-trapping, buoyant abilities ...
Phys.org / Did you hear the one about scientists telling jokes? Not many did, according to a study of humor at conferences
To engage audiences and help keep their attention, many public speakers sprinkle their speeches with a little humor. It's a useful tool, but something that scientists rarely use, according to a report into humor at science ...
Phys.org / Ancient 'syphilis-like' disease in Vietnam challenges long-held assumptions on congenital infection
The findings of a new study by a Charles Sturt University researcher and colleagues challenge a long-standing assumption used by scientists studying ancient disease. The study is published in the International Journal of ...
Phys.org / Why cultivating drought-resistant plants disappoints: Soil physics may be the real bottleneck
Plants need water, light, and air to thrive. But when they transport water from the soil up to their leaves, they defy gravity. Scientists describe this astonishing phenomenon as "negative water potential," a form of negative ...
Phys.org / New findings on the first steps in protein synthesis
In the earliest phase of creating human proteins, the protein complex NAC performs an essential task by starting the first steps toward folding proteins into their correct three-dimensional structures. An international research ...
Phys.org / The evolutionary secret of the California poppy's alkaloids
Characteristic features of plants, such as their active ingredients or flower color, may have developed through very different evolutionary histories. This is shown by an international study on the orange-flowering California ...
Phys.org / Astronomers discover 87 stellar stream candidates in the Milky Way
Stellar streams are trails of stars that astronomers can study to solve mysteries about the history of our Milky Way galaxy and, potentially, the dark matter that helps shape the cosmos despite eluding direct observation. ...
Phys.org / Hubble revisits Crab Nebula to track 25 years of expansion
Nearly a millennium ago, astronomers witnessed a brilliant new star blazing in the sky—a supernova so bright it was visible in daylight for weeks. Today, its expanding remnant, the Crab Nebula, continues to evolve 6,500 ...
Phys.org / The 'silent takeover': Invasive bees are reshaping Chile's unique pollination networks
Biological invasions are a major driver of biodiversity loss and invasive pollinators can reshape native plant-pollinator networks. A new study published in the journal NeoBiota reveals that invasive pollinators are fundamentally ...
Phys.org / Gran Dolina site at Atapuerca reveals almost exclusive use of local chert 400,000 years ago
A paper published in the journal Quaternary International reveals a distinctive technological behavior at level TD10.2-BB of Gran Dolina (Atapuerca, Burgos), characterized by the almost exclusive use of local chert and linked ...
