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 / 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 / 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 / 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 / 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 ...
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 / 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 / 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 / First quantum oscillations observed in gallium nitride holes
Gallium nitride, a semiconductor that can operate at high voltages, temperatures, and frequencies, has enabled technologies from LED lighting to high-power electronics. Now Cornell researchers have observed a quantum property ...
Phys.org / Unlocking longevity insights from ancient bristlecone pine
What can the world's longest living individual teach us about longevity? A team of scientists coordinated by the University of California, Davis, sequenced the Great Basin bristlecone pine genome, which could help unlock ...
Phys.org / A sudden surge in luminosity: Stacked dyes hint at brighter organic semiconductors
In nature, a certain size is often a prerequisite for biomolecules to perform their specific functions. For example, for proteins or DNA to fulfill their vital tasks, they must be folded in a precise manner—and this requires ...
Phys.org / Wildflower folk remedy shows modern potential for tackling antibiotic resistance
Scientists have proven that a wildflower steeped in folklore for its medicinal powers has genuine healing qualities—and the potential to help combat antibiotic resistance. Tormentil, a yellow wildflower found in heath and ...
