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 / 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 / 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 / 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 light-years ...
Phys.org / 'Space archaeology' reveals first dynamic history of a giant spiral galaxy
A team of astronomers led by the Center for Astrophysics | Harvard and Smithsonian have for the first time used galactic archaeology, the study of detailed chemical fingerprints in deep space, to trace the history of a galaxy ...
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 / 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 / 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 / Electric current stabilizes spins at unstable points for new types of computing
A research team has discovered a new way to control tiny magnetic properties inside materials using electric current, which could possibly pave the way for new types of computing technologies. The work is based on spintronics, ...
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 / An end to the battle between touchscreens and long fingernails is on the horizon
Anybody who has tried to use a smartphone or tablet with long nails knows that there's a learning curve. Rather than effortlessly tapping with a fingertip, you must awkwardly lay the pads of your fingers onto the screen. ...
